The following day, Theresa propped her elbows on the mat, legs straight, feet balanced on their tips, her core taut and trembling. Sweat cascaded from her forehead, each drop falling audibly to the floor beneath her. She had held the plank position for nearly an hour. Her whole body was soaked with sweat. The intense training regimen of the past ten days had transformed her. Though her weight hadn't shifted much, her physique had undergone a complete metamorphosis. Her body, once soft and unrefined, was now a masterpiece of lean muscle and defined lines. Her abs rippled, her arms and legs were taut with strength, and every inch of her radiated raw power. Her mind, too, had sharpened. The grueling exercise gave her focus, an edge that set her apart from the desperate masses outside. Her sharp, predatory gaze alone could suppress an entire room. This was the difference between a prey and a predator. Gritting her teeth, Theresa made the final push. Her body felt immensely heavy. Pain flooded her senses as the sweat on her forehead dripped like rain. Sh*t! Her muscles trembled violently. But no! I can't give up! Just a little more! Every second of persistence was a breakthrough in her physical fitness. Most importantly, the reward time was about to end. Then, at the peak of her agony, the voice she'd come to rely on echoed in her mind. 'Ding! Time's up. Physical enhancement completed!' With an audible thud, Theresa collapsed onto the mat, gasping for air. It's over, for now. I can finally rest. At this moment, she could no longer move a finger. The pain was brutal, but the rewards were worth it. 'Progress evaluation. Host's stamina enhancement—Completed! 'Speed enhancement—Completed! 'Endurance enhancement—Completed! 'Strength enhancement—Completed! 'Congratulations! You've achieved an S-grade rating! 'Congratulations on achieving doubled stamina enhancement! Doubled speed! Doubled endurance! Doubled healing speed! A bonus of Advanced Combat Techniques! A lifespan of a hundred years!' Theresa was shocked. As she processed the announcement, she felt her body undergoing a dramatic transformation.The exhaustion that had pinned her to the floor dissipated in an instant, replaced by an electrifying surge of vitality. Strength coursed through her veins as Theresa sprang to her feet effortlessly. Her movements were precise and faster than ever. She walked outside the camp, her eyes locking onto her prized possession—an armored vehicle. She felt an urge to lift it. The wild idea took hold of her. Moving toward it, she gripped one corner of the vehicle's frame as she dug her feet into the ground. With a mighty heave, the vehicle's corner lifted off the ground by a full centimeter. The 8x8 armored vehicle weighed over 20 tons. She tested her speed next, breaking into a full sprint. Her pace rivaled that of an Olympic sprinter. Physical fitness was a huge barrier that could only be improved with persistence.Yet, the reward system gave her a double of that. Her physical capabilities were now leagues beyond the average human. The rewards weren't limited to her body. During her current state, she could rival those ordinary speed and strength ability users. This is amazing! Back in her domain, a pristine manual on martial arts awaited her. Theresa immediately flipped through the pages. After scheming through a few moves, her eyes lit up. The techniques detailed within were precise, ruthless, and devastatingly effective. Every move targeted critical points, designed for maximum lethality against humans and zombies alike. No wonder it is said to be far superior to the current martial arts. Each move is a summary of decades of martial artists.Theresa felt like she had found a treasure. For the next five days, she threw herself into training. Her mornings began with a run around the mountain. After her warm-up, she began practicing her martial arts. Between training, she would cook and have meals with Summer. She would manage her growing farm as well. Her chickens, ducks, and sheep were thriving, and her vegetable garden was lush with life. Eggs piled up faster than she could eat them. In ten days. her greens would be ready to harvest. Theresa only took a few daily necessities for herself every day, leaving the rest in the coop for the old hens to hatch eggs. Her camp was thriving and developing well. Meanwhile, the outside world was unraveling fast.Yesterday evening, she stood on the watchtower when she saw the lights of Ansford flickering and dying. Around 8 p.m., the city plunged into darkness, the power grid collapsing like a row of dominoes. The power was cut off in advance. In her previous life, the electricity lasted for a long time. But it only lasted for half a month in this lifetime. After all, the virus broke out early, and the uncontrollable factors are shifting. The power plant must be doomed. This lifetime is much more difficult than the previous one. Electricity was the basic energy source. In her previous life, Theresa relied on electricity for cooking and drinking when natural gases were cut off. At night, she could observe the situation through the sound-controlled lights and surveillance. Without electricity, survival had become exponentially harder. Theresa stood on the watchtower. Desperate screams and car horns were coming from the city ahead.Boom! Through her infrared camera, she saw vehicles speeding out of the city in frantic waves. Behind them, hordes of zombies followed. Beyond the darkness, chaos was palpable. Desperate drivers collided with one another, the sounds of crashes echoing through the air. Half a month was all it had taken for people to finally come to terms with the cold, unrelenting truth that no rescue was coming. The lights going out wasn't just the end of electricity; it was the end of hope. Now, the one thing left for them to do was run. Theresa knew a new wave of exodus was coming. The next morning, she stood on the tower again. Wrecked cars were strewn across the road on the narrow road leading out of the city. The wandering zombies on the main road began to increase. Some were hunched over the smashed vehicles, while others shuffled aimlessly among the wreckage. There were even some who wandered into her territory. Her hand instinctively reached for her crossbow and aimed for a reckless zombie. Yet, she halted her moves.
