Most of the regulars hadn&#8217;t shown up, either out of respect for the crisis unfolding or because they simply didn&#8217;t know what to say. The few who had arrived moved in hushed whispers, casting furtive glances toward Elara&#8217;s workstation.<\/p>\n\n\n\n<p>Elara hadn&#8217;t moved from her chair in eighteen hours.<\/p>\n\n\n\n<p>Her eyes were red-rimmed and swollen, her hair a tangled mess, her clothes rumpled from the sleepless night. She&#8217;d stopped crying hours ago\u2014there were no tears left\u2014but the hollow ache in her chest hadn&#8217;t faded. If anything, it had grown worse.<\/p>\n\n\n\n<p>The Vault&#8217;s dashboard glowed on her main screen, a constant reminder of her failure:<\/p>\n\n\n\n<p><strong>Total Value Locked: $7,500,000 (\u2193 84.1%)<\/strong><br><strong>Active Users: 51,247 (Unchanged)<\/strong><br><strong>Withdrawals (24h): 47<\/strong><\/p>\n\n\n\n<p>Forty-seven withdrawals. Forty-seven recursive calls. Forty-seven moments when she could have stopped it, if only she&#8217;d been paying attention.<\/p>\n\n\n\n<p>She&#8217;d been at lunch. Laughing with friends. Making jokes about other people&#8217;s bad code.<\/p>\n\n\n\n<p><em>I was laughing while my users were being robbed.<\/em><\/p>\n\n\n\n<p>The thought was a knife twisting in her gut. She&#8217;d replayed the attack hundreds of times in her head, searching for something she could have done differently. If she&#8217;d checked her phone sooner. If she&#8217;d taken Ronen&#8217;s warning seriously. If she&#8217;d just fixed the vulnerability when she&#8217;d had the chance.<\/p>\n\n\n\n<p>But she hadn&#8217;t. And now fifty-one thousand people were paying the price.<\/p>\n\n\n\n<p>Elara pulled up the audit log, scrolling through the reports she&#8217;d once been so proud of. AuditOne, ChainSafe, BlockProof\u2014three independent security firms, all giving The Vault their highest rating.<\/p>\n\n\n\n<p><em>&#8220;&#8230;no critical vulnerabilities identified&#8230;&#8221;<\/em><br><em>&#8220;&#8230;re-entrancy guard implementation follows industry best practices&#8230;&#8221;<\/em><br><em>&#8220;&#8230;withdrawal function is secure against recursive attacks&#8230;&#8221;<\/em><\/p>\n\n\n\n<p>The words blurred on the screen. They&#8217;d been so confident. So certain. Just like she&#8217;d been.<\/p>\n\n\n\n<p>But the auditors had made the same mistake she had. They&#8217;d tested each function individually, verifying the re-entrancy guard on the withdrawal function and moving on. They&#8217;d never considered cross-function interactions. They&#8217;d never tested&nbsp;<code>updateUserInterest()<\/code>&nbsp;in combination with&nbsp;<code>withdraw()<\/code>.<\/p>\n\n\n\n<p>And now millions were gone.<\/p>\n\n\n\n<p>Elara opened the auditor&#8217;s methodology document, scanning the testing procedures they&#8217;d used. It was thorough\u2014detailed, even\u2014but there was a glaring hole in their approach. They&#8217;d assumed that because the withdrawal function was protected, the entire contract was protected. They&#8217;d never considered that an attacker might simply take a different path.<\/p>\n\n\n\n<p><em>Cross-function re-entrancy,<\/em>&nbsp;she thought bitterly.&nbsp;<em>The one thing none of us thought to test for.<\/em><\/p>\n\n\n\n<p>She pulled up Ronen&#8217;s original email, reading it again with fresh eyes:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><em>&#8220;I&#8217;ve been analyzing The Vault&#8217;s codebase and have identified what I believe is a serious re-entrancy vulnerability.

An attacker could use this function to bypass the guard and execute a cross-function re-entrancy attack, draining funds recursively.&#8221;<\/em><\/p>\n<\/blockquote>\n\n\n\n<p>He&#8217;d been so clear. So thorough. He&#8217;d even attached a proof-of-concept, demonstrating exactly how the attack would work.<\/p>\n\n\n\n<p>And she&#8217;d ignored him.<\/p>\n\n\n\n<p><em>Why?<\/em>&nbsp;she asked herself, not for the first time.&nbsp;<em>Why didn&#8217;t I listen?<\/em><\/p>\n\n\n\n<p>The answer was as painful as it was obvious: because she&#8217;d thought she was better than him. Because she&#8217;d built The Vault, and he was just some kid with a debugger. Because she&#8217;d had three audits, and he was nobody.<\/p>\n\n\n\n<p>She&#8217;d been so arrogant. So certain that she was right.<\/p>\n\n\n\n<p>And now she was paying the price.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>At 7:23 AM, Elara&#8217;s phone started buzzing.<\/p>\n\n\n\n<p>She&#8217;d been dreading this moment. The first wave of messages from users had come in overnight\u2014confused, concerned, pleading for information. She&#8217;d ignored them, unable to face the words. But now the flood was beginning in earnest.<\/p>\n\n\n\n<p><strong>Forum Post: &#8220;THE VAULT IS EMPTY &#8211; What happened to our funds?&#8221;<\/strong><\/p>\n\n\n\n<p>The post had already received hundreds of replies.

The Code Nexus had a dedicated news feed that tracked blockchain-related stories, and it was now dominated by a single topic:<\/p>\n\n\n\n<p><strong>&#8220;The Vault Exploit: Teen Developer&#8217;s Code Flaw Costs Users Millions&#8221;<\/strong><\/p>\n\n\n\n<p>Elara opened the article, her stomach churning.

He&#8217;d seen her potential, nurtured her talent, pushed her to be better. He was the one who&#8217;d encouraged her to build The Vault, who&#8217;d reviewed her early code, who&#8217;d connected her with the auditors.<\/p>\n\n\n\n<p>His holographic image flickered to life on her screen, and Elara felt her throat tighten. She knew what was coming.<\/p>\n\n\n\n<p>&#8220;Elara,&#8221; he said, his voice heavy with disappointment. &#8220;I&#8217;ve been trying to reach you for hours.&#8221;<\/p>\n\n\n\n<p>&#8220;I&#8217;m sorry,&#8221; she whispered. &#8220;I couldn&#8217;t\u2014I didn&#8217;t know what to say.&#8221;<\/p>\n\n\n\n<p>Alistair sighed, rubbing his temples. He looked older than she remembered, the lines on his face deeper, the shadows under his eyes more pronounced.<\/p>\n\n\n\n<p>&#8220;I read the audit reports,&#8221; he said. &#8220;The vulnerability was there. Clear as day. The auditors missed it, you missed it, I missed it. We all did.&#8221;<\/p>\n\n\n\n<p>&#8220;I should have caught it,&#8221; Elara said, her voice breaking. &#8220;Ronen showed me the proof-of-concept. He warned me. And I\u2014&#8221;<\/p>\n\n\n\n<p>&#8220;You dismissed him.&#8221; Alistair&#8217;s voice was gentle but firm. &#8220;I know. I&#8217;ve seen the emails.&#8221;<\/p>\n\n\n\n<p>Elara closed her eyes, unable to face his gaze. &#8220;I was so sure I was right. I thought\u2014&#8221;<\/p>\n\n\n\n<p>&#8220;Pride,&#8221; Alistair said quietly. &#8220;It&#8217;s the most dangerous thing a developer can have. You thought you knew better. And now\u2014&#8221; He gestured helplessly at the screens around them. &#8220;Now we&#8217;re all paying for it.&#8221;<\/p>\n\n\n\n<p>&#8220;I&#8217;m sorry,&#8221; Elara said again, the words inadequate, useless. &#8220;I&#8217;m so sorry. I&#8217;ve ruined everything. My reputation, the project, the users&#8217; trust. Everything.&#8221;<\/p>\n\n\n\n<p>Alistair was silent for a long moment. When he spoke, his voice was softer, almost sad.<\/p>\n\n\n\n<p>&#8220;Your reputation can be rebuilt. The project can be fixed. But the trust\u2014that&#8217;s going to take time. A lot of time. And you&#8217;re going to have to work for it.&#8221;<\/p>\n\n\n\n<p>&#8220;I don&#8217;t know if I can,&#8221; Elara admitted. &#8220;I don&#8217;t know if I deserve to.&#8221;<\/p>\n\n\n\n<p>&#8220;Maybe you don&#8217;t.&#8221; Alistair&#8217;s words were blunt, but not cruel. &#8220;But that&#8217;s not the question. The question is whether you&#8217;re going to try anyway.&#8221;<\/p>\n\n\n\n<p>Elara stared at him, tears streaming down her face. &#8220;I don&#8217;t know how. I don&#8217;t know where to start.&#8221;<\/p>\n\n\n\n<p>&#8220;You start by taking responsibility,&#8221; Alistair said. &#8220;You face your users. You tell them the truth. And then you start fixing what you broke.&#8221;<\/p>\n\n\n\n<p>&#8220;What if they don&#8217;t forgive me?&#8221;<\/p>\n\n\n\n<p>&#8220;Then you keep trying anyway.&#8221; Alistair leaned forward, his holographic image flickering with intensity. &#8220;That&#8217;s what it means to be a leader, Elara. Not being perfect. Being willing to fix your mistakes.&#8221;<\/p>\n\n\n\n<p>He paused, letting the words sink in.<\/p>\n\n\n\n<p>&#8220;You built something incredible. You&#8217;re going to make mistakes. We all do. What matters is what you do next.&#8221;<\/p>\n\n\n\n<p>Elara nodded slowly, wiping the tears from her face. &#8220;I&#8217;ll try,&#8221; she said. &#8220;I&#8217;ll do whatever it takes to make this right.&#8221;<\/p>\n\n\n\n<p>Alistair nodded, a flicker of the old warmth in his eyes. &#8220;That&#8217;s all I can ask for. Now go. You&#8217;ve got work to do.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>At 9:34 AM, Ronen arrived.<\/p>\n\n\n\n<p>He walked into the Code Nexus with the quiet determination of someone who&#8217;d already made up his mind. His workspace was behind him, his screens dark, his proof-of-concept packed away.<\/p>\n\n\n\n<p>He wasn&#8217;t there to work. He was there to help.<\/p>\n\n\n\n<p>&#8220;Elara,&#8221; he said, stopping at her workstation. &#8220;I&#8217;ve been tracking the attacker&#8217;s contract. There&#8217;s something you need to see.&#8221;<\/p>\n\n\n\n<p>She looked up, her eyes red-rimmed, her voice hoarse. &#8220;I don&#8217;t think I can handle any more bad news.&#8221;<\/p>\n\n\n\n<p>&#8220;It&#8217;s not bad news.&#8221; He pulled up a chair beside her, activating a secondary screen. &#8220;It&#8217;s an opportunity.&#8221;<\/p>\n\n\n\n<p>Elara stared at him, confused. &#8220;An opportunity? How can any of this be an opportunity?&#8221;<\/p>\n\n\n\n<p>Ronen pulled up the attacker&#8217;s contract, highlighting a section of code. &#8220;They made a mistake,&#8221; he said. &#8220;They were so focused on stealing the funds that they forgot to protect the loot.&#8221;<\/p>\n\n\n\n<p>He pointed to a line in the contract. &#8220;This variable here\u2014the access key for their withdrawal function. It&#8217;s stored as a public variable. Anyone can read it. Anyone can use it.&#8221;<\/p>\n\n\n\n<p>Elara squinted at the code, her brain slowly processing what he was saying. &#8220;So we can\u2014&#8221;<\/p>\n\n\n\n<p>&#8220;We can execute the same re-entrancy attack against them,&#8221; Ronen said. &#8220;We can drain their contract and recover the stolen funds.&#8221;<\/p>\n\n\n\n<p>Elara&#8217;s breath caught in her throat. It was audacious. Dangerous. Possibly illegal.<\/p>\n\n\n\n<p>But it was also exactly what she&#8217;d been hoping for.<\/p>\n\n\n\n<p>&#8220;Will it work?&#8221; she asked, her voice barely above a whisper.<\/p>\n\n\n\n<p>&#8220;It will work,&#8221; Ronen said. &#8220;But we have to be fast. The attacker is going to move the funds soon. If we wait too long, they&#8217;ll be gone forever.&#8221;<\/p>\n\n\n\n<p>&#8220;How long do we have?&#8221;<\/p>\n\n\n\n<p>Ronen checked his monitoring dashboard. &#8220;Twenty-four hours. Maybe less. The attacker is smart\u2014they won&#8217;t leave the funds sitting there for long.&#8221;<\/p>\n\n\n\n<p>Elara stared at the contract on the screen, her mind racing with possibilities. A white hat rescue. It was risky, dangerous, and morally complicated.<\/p>\n\n\n\n<p>But it was also the only chance they had.<\/p>\n\n\n\n<p>&#8220;What do we need?&#8221; she asked.<\/p>\n\n\n\n<p>Ronen smiled\u2014a small, determined expression. &#8220;A team. A plan. And a lot of luck.&#8221;<\/p>\n\n\n\n<p>&#8220;We have two of those,&#8221; Elara said. &#8220;Let&#8217;s make the third happen.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>The team came together over the next few hours.<\/p>\n\n\n\n<p>Ronen reached out to his contacts in the white hat community, and two volunteers responded almost immediately. Zara was a nineteen-year-old security researcher who&#8217;d done white hat rescues before. Marcus was eighteen, a coding prodigy who&#8217;d built his own security tools for analyzing smart contracts.<\/p>\n\n\n\n<p>They arrived at the Code Nexus by noon, their faces serious, their minds focused.<\/p>\n\n\n\n<p>&#8220;The attacker&#8217;s contract is called &#8216;The Vault Keeper,'&#8221; Ronen explained, pulling up a diagram on the main screen. &#8220;It holds the stolen funds in a simple withdrawal function. The key is stored as a public variable.&#8221;<\/p>\n\n\n\n<p>He highlighted the vulnerability. &#8220;Here&#8217;s where it gets interesting. The withdrawal function doesn&#8217;t check who&#8217;s calling it. It just checks that the key is correct. And since the key is public, anyone can call it.&#8221;<\/p>\n\n\n\n<p>&#8220;Anyone?&#8221; Zara asked, her eyes narrowing.<\/p>\n\n\n\n<p>&#8220;Anyone,&#8221; Ronen confirmed. &#8220;Including us.&#8221;<\/p>\n\n\n\n<p>Marcus let out a low whistle. &#8220;That&#8217;s sloppy. They went to all that trouble to steal the funds and forgot to lock them down.&#8221;<\/p>\n\n\n\n<p>&#8220;Greed,&#8221; Elara said quietly. &#8220;They were so focused on the attack that they didn&#8217;t think about the aftermath.&#8221;<\/p>\n\n\n\n<p>&#8220;Maybe,&#8221; Ronen said. &#8220;Or maybe they just got cocky. Either way, it gives us an opening.&#8221;<\/p>\n\n\n\n<p>He pulled up their rescue plan. &#8220;We&#8217;ll deploy a contract called &#8216;The Recovery.&#8217; It will call the withdrawal function on The Vault Keeper, using the public key. Then it will execute the same re-entrancy attack, draining the contract before The Vault Keeper can update its balance.&#8221;<\/p>\n\n\n\n<p>&#8220;The same attack?&#8221; Zara asked, her voice skeptical. &#8220;The one that drained The Vault?&#8221;<\/p>\n\n\n\n<p>&#8220;Exactly,&#8221; Ronen said. &#8220;We&#8217;ll use their own technique against them. Poetic justice.&#8221;<\/p>\n\n\n\n<p>&#8220;And the risks?&#8221; Marcus asked.<\/p>\n\n\n\n<p>Ronen&#8217;s expression grew serious. &#8220;The attack has to execute in a single block. If we&#8217;re too slow, the transaction fails. If the attacker notices and front-runs us, we lose everything. We have one chance to get this right.&#8221;<\/p>\n\n\n\n<p>Elara felt the weight of his words. One chance. Everything riding on it.<\/p>\n\n\n\n<p>But there was no other option. The stolen funds were slipping away by the hour. If they didn&#8217;t act now, they&#8217;d never get another opportunity.<\/p>\n\n\n\n<p>&#8220;We&#8217;ll do it,&#8221; she said. &#8220;Whatever it takes.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>The night was spent in preparation.<\/p>\n\n\n\n<p>Zara set up monitoring on The Vault Keeper, tracking any movement on the contract. Marcus built a simulation environment to test the rescue contract. Ronen wrote the core code, checking and rechecking every line.<\/p>\n\n\n\n<p>And Elara\u2014Elara worked on the new Vault contract.<\/p>\n\n\n\n<p>It was the part of the plan that no one had mentioned yet. Once they recovered the funds, they&#8217;d need somewhere to put them. The old Vault was compromised, its security broken. They&#8217;d need a new contract, one with every protection they could think of.<\/p>\n\n\n\n<p>&#8220;Re-entrancy guards on every state-changing function,&#8221; she muttered, typing furiously. &#8220;Checks-effects-interactions pattern on all withdrawable functions. Formal verification of the entire codebase. Multiple layers of security.&#8221;<\/p>\n\n\n\n<p>She was designing a fortress. A Vault that couldn&#8217;t be breached.<\/p>\n\n\n\n<p>But she knew it wasn&#8217;t about the code anymore. It was about trust. And trust couldn&#8217;t be coded.<\/p>\n\n\n\n<p>&#8220;You okay?&#8221; Ronen asked, appearing beside her with a cup of coffee.<\/p>\n\n\n\n<p>She took it gratefully, sipping the bitter liquid. &#8220;I&#8217;m trying to be. I don&#8217;t know if I&#8217;m succeeding.&#8221;<\/p>\n\n\n\n<p>&#8220;One step at a time,&#8221; he said. &#8220;That&#8217;s how we get through this.&#8221;<\/p>\n\n\n\n<p>Elara nodded, staring at the code on her screen. &#8220;When this is over,&#8221; she said quietly, &#8220;I&#8217;m going to make things right. For every user. For everyone I let down.&#8221;<\/p>\n\n\n\n<p>&#8220;I know you will.&#8221;<\/p>\n\n\n\n<p>&#8220;You believe in me,&#8221; she said, surprised. &#8220;Even after everything I did?&#8221;<\/p>\n\n\n\n<p>Ronen met her eyes, his expression serious. &#8220;You made a mistake. A big one. But you&#8217;re trying to fix it. That&#8217;s what matters.&#8221;<\/p>\n\n\n\n<p>&#8220;What if it&#8217;s not enough?&#8221;<\/p>\n\n\n\n<p>Ronen smiled\u2014a small, gentle expression. &#8220;Then we&#8217;ll try again. And again. Until it is.&#8221;<\/p>\n\n\n\n<p>Elara felt tears prick at her eyes again, but this time they weren&#8217;t tears of despair. They were tears of gratitude, of hope.<\/p>\n\n\n\n<p>&#8220;Thank you,&#8221; she whispered. &#8220;For not giving up on me.&#8221;<\/p>\n\n\n\n<p>Ronen squeezed her shoulder. &#8220;We&#8217;re not done yet. Come on\u2014let&#8217;s finish this.&#8221;<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>At 2:37 AM, the plan was ready.<\/p>\n\n\n\n<p>The Recovery contract was deployed on a test blockchain, and the team ran the simulation one final time. It worked perfectly\u2014the recursive calls drained the test contract in seconds, transferring the funds to a new Vault.<\/p>\n\n\n\n<p>&#8220;Now we do it for real,&#8221; Zara said.<\/p>\n\n\n\n<p>Elara&#8217;s hands were shaking. &#8220;What if it fails?&#8221;<\/p>\n\n\n\n<p>&#8220;It won&#8217;t,&#8221; Marcus said. &#8220;We&#8217;ve tested it forty times. It works.&#8221;<\/p>\n\n\n\n<p>&#8220;The attacker\u2014&#8221;<\/p>\n\n\n\n<p>&#8220;Won&#8217;t know what hit them,&#8221; Ronen interrupted. &#8220;We&#8217;ve been watching their contract for hours. No activity. They&#8217;re probably sleeping.&#8221;<\/p>\n\n\n\n<p>Or celebrating, Elara thought. They were probably toasting their success while she was here, trying to undo the damage.<\/p>\n\n\n\n<p>The thought made her angry. Not just at herself\u2014but at The Attacker. They&#8217;d stolen from people who couldn&#8217;t afford to lose. They&#8217;d destroyed lives for profit.<\/p>\n\n\n\n<p>She was going to make them pay.<\/p>\n\n\n\n<p>&#8220;Let&#8217;s do this,&#8221; she said, her voice firm.<\/p>\n\n\n\n<p>Ronen nodded, activating the rescue contract on his screen. &#8220;On three. Zara, monitor the mempool. Marcus, be ready to block any front-running attempts. Elara, you&#8217;re on the new Vault\u2014make sure the recovered funds go there.&#8221;<\/p>\n\n\n\n<p>&#8220;Ready,&#8221; Zara said.<\/p>\n\n\n\n<p>&#8220;Ready,&#8221; Marcus confirmed.<\/p>\n\n\n\n<p>Elara took a deep breath, her fingers hovering over the keyboard. &#8220;Ready.&#8221;<\/p>\n\n\n\n<p>Ronen&#8217;s eyes met hers, and she saw something in them\u2014determination, trust, and a shared commitment to making things right.<\/p>\n\n\n\n<p>&#8220;Let&#8217;s go,&#8221; he said. &#8220;One.&#8221;<\/p>\n\n\n\n<p>The team tensed.<\/p>\n\n\n\n<p>&#8220;Two.&#8221;<\/p>\n\n\n\n<p>Elara&#8217;s heart pounded in her chest.<\/p>\n\n\n\n<p>&#8220;Three.&#8221;<\/p>\n\n\n\n<p>She pressed the enter key.<\/p>\n\n\n\n<p>The transaction was sent.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong><em>Table of contents:<\/em><\/strong><br><a href=\"https:\/\/nightfame.com\/style\/the-re-entrancy-heist-science-fiction-story\/\">Introduction<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-1-the-vault-contract-the-re-entrancy-heist\/\">Chapter 1: The Vault Contract<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-2-a-withdrawal-request-the-re-entrancy-heist\/\">Chapter 2: A Withdrawal Request<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-3-the-recursive-call-the-re-entrancy-heist\/\">Chapter 3: The Recursive Call<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-4-draining-the-treasury-the-re-entrancy-heist\/\">Chapter 4: Draining the Treasury<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-5-the-frozen-audit-log-the-re-entrancy-heist\/\">Chapter 5: The Frozen Audit Log<\/a> <strong>&lt;&lt;&lt;&lt;&lt;&lt; NEXT<\/strong><br><a href=\"https:\/\/nightfame.com\/style\/chapter-6-the-emergency-pause-the-re-entrancy-heist\/\">Chapter 6: The Emergency Pause<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-7-a-time-locked-patch-the-re-entrancy-heist\/\">Chapter 7: A Time-Locked Patch<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-8-the-white-hat-rescue-the-re-entrancy-heist\/\">Chapter 8: The White Hat Rescue<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-9-the-forked-recovery-the-re-entrancy-heist\/\">Chapter 9: The Forked Recovery<\/a><br><a href=\"https:\/\/nightfame.com\/style\/chapter-10-code-is-not-trust-the-re-entrancy-heist\/\">Chapter 10: Code Is Not Trust<\/a><\/p>\n<div class=\"pvc_clear\"><\/div><p id=\"pvc_stats_61026\" class=\"pvc_stats all  \" data-element-id=\"61026\" style=\"\"><i class=\"pvc-stats-icon medium\" aria-hidden=\"true\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"far\" data-icon=\"chart-bar\" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 512 512\" class=\"svg-inline--fa fa-chart-bar fa-w-16 fa-2x\"><path fill=\"currentColor\" d=\"M396.8 352h22.4c6.4 0 12.8-6.4 12.8-12.8V108.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v230.4c0 6.4 6.4 12.8 12.8 12.8zm-192 0h22.4c6.4 0 12.8-6.4 12.8-12.8V140.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v198.4c0 6.4 6.4 12.8 12.8 12.8zm96 0h22.4c6.4 0 12.8-6.4 12.8-12.8V204.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v134.4c0 6.4 6.4 12.8 12.8 12.8zM496 400H48V80c0-8.84-7.16-16-16-16H16C7.16 64 0 71.16 0 80v336c0 17.67 14.33 32 32 32h464c8.84 0 16-7.16 16-16v-16c0-8.84-7.16-16-16-16zm-387.2-48h22.4c6.4 0 12.8-6.4 12.8-12.8v-70.4c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v70.4c0 6.4 6.4 12.8 12.8 12.8z\" class=\"\"><\/path><\/svg><\/i> <img loading=\"lazy\" decoding=\"async\" width=\"16\" height=\"16\" alt=\"Loading\" src=\"https:\/\/nightfame.com\/style\/wp-content\/plugins\/page-views-count\/ajax-loader-2x.gif\" border=0 \/><\/p><div class=\"pvc_clear\"><\/div>","protected":false},"excerpt":{"rendered":"<p>The Code Nexus had never been this quiet.
