At the company's annual gala, the CEO announced that this year's top sales performer would receive a two-million-dollar year-end bonus. I was the top performer. However, my manager called me into his office the very next day and explained that the company was cutting costs and improving efficiency. As a result, my bonus had to be reduced. I initially assumed everyone's bonus was being cut. Then, I found out I was the only one getting shortchanged. Even worse, they handed my position to a useless coworker who could barely do the job. I understood everything immediately. 'So this is how it is. You're tossing me aside after you got what you wanted from me.' Fine. I stopped putting in any effort from that day forward. I clocked in, did the bare minimum, and watched the company slowly fall apart. Sales began to drop month after month. Even the major clients I had already secured began withdrawing their investments. That was when the CEO finally panicked. He showed up at my front door, begging me to fix things. I kicked the door open and looked down at him. "You think a garbage company like yours deserves my help?"

Emily Carter once believed love could overcome anything. For two years, she devoted herself completely to Jason Walker, sacrificing her dreams, savings, and happiness to build a future with him. When the zombie virus suddenly plunged the world into chaos, Emily never hesitated to protect him. She scavenged dangerous streets for food and medicine, fought countless zombies to keep him alive, and repeatedly placed herself in mortal danger so he could survive another day. Three months into the apocalypse, everything she believed shattered. Cornered by an overwhelming zombie horde, Jason abandoned Emily without hesitation, choosing to save his secret lover, Vanessa Kane, instead. As Emily lay dying, surrounded by the undead, she realized that every sacrifice she had made had been for someone who never truly loved her. Instead of dying, Emily awakens exactly one month before the outbreak begins. She remembers every horrifying detail of her previous life—the collapse of society, the rise of mutant zombies, the betrayal of trusted allies, and the locations of future safe zones and supply caches. At the same moment, a mysterious voice echoes inside her mind. “SSS-Level Survival System Activated.” The system grants Emily missions, rewards, powerful skills, and access to a limitless storage space, allowing her to prepare for the coming apocalypse far better than anyone else. Unlike her first life, she refuses to waste her second chance chasing love or relying on others for survival. Her only priorities are staying alive, protecting those who deserve her trust, uncovering the truth behind the virus, and building a secure settlement capable of surviving the end of the world.

The project I had poured my heart and soul into earned the company over a hundred million in profit, yet the credit was handed to the vice president's nephew. I stood in a corner, the stack of source code documents trembling in my hands, nearly crushed by my grip. That nephew—who couldn't even get Hello World to compile—was now on stage, smiling brightly as he accepted the award. The vice president came over and draped an arm around my shoulder like we were old friends. "You're just an outsourced worker," he said casually. "These honors wouldn't mean anything to you anyway. Jason is new. He's got limitless potential. From now on, you'll be responsible for mentoring him properly." Only then did I realize that decades of struggle had been nothing more than laying out a red carpet for someone else's glory. That very night, while reviewing the project's code repository, I discovered a massive flaw—one serious enough to bring the entire system crashing down within three days.

After a grueling year of training abroad on the company's dime, I came home holding an OEM certification for our high-end production line. Only three people in the country had it. I couldn't wait to cash in my stock options and finally give my girlfriend, Nora, a home of our own. But when I got back to the office, there was no celebration waiting. Just three notices. [Finance: $50,000 travel reimbursement rejected. $20,000 in salary frozen as a performance hold, to be released after your review is passed.] [HR: Your sponsored training carries a mentoring obligation. You must train three qualified technicians within one month of returning, as your assessment. Fail, and your travel costs will not be reimbursed and your frozen salary will be forfeited.] [Direct Manager, Kevin: Turn over all core technical documentation. Effective tomorrow, you're reassigned to the factory floor for mentoring.] I gripped the three notices and headed for the manager's office to demand an explanation. I pushed the door open and froze. Nora, my girlfriend of three years, was sitting on Kevin's lap, her clothes half undone. Our eyes met. All she gave me was one cold line. "Ethan, since you've already seen it, let's just break up." I backed out of the office without a word. I walked past all the eager faces waiting for a show, went back to my desk, and finally answered the email that had been sitting in my inbox for a week. [I've decided to accept your offer. I can start in a month.] One month. Everything this company owed me, I was going to take back myself.
