Doomsday: with unlimited warehouse system

David absorbed the crystals one by one, and his whole body was drenched in sweat as if he had been through a great ordeal. His face was flushed, and his arms had turned red. His legs were completely immobile, and he couldn't even move them slightly.

David continued to endure the pain until he absorbed the remaining twenty crystals. After the last crystal was absorbed, David suddenly felt a huge relief, and his whole body relaxed.

[Ding! ]

[Your spatial ability has been upgraded to Level 4. Activating System Discovery Function 3.]

[Function 3: Know Yourself and Others.]

[Can detect one's own condition and the physical qualities, ability types, and levels of others, etc.]

[Usage limit per day: 3 times]

David was momentarily stunned by Function 3, but quickly shifted his attention to himself. His hands were trembling slightly, and the muscles on his arms were very pronounced. He had greatly improved in terms of physical fitness.

David's mouth curled up slightly. The feeling of being Level 4 was different. But what about his skills? With a thought, David held a spatial blade in his hand. He walked up to the window, leaned against it, and carefully lifted a corner of the curtain. There were already many zombies on the street, and soon David's gaze fell on a large-sized zombie.

"System, scan." David summoned the system.

With a beep, a panel-like object appeared in front of David.

[Level 4 Zombie]

[Attribute: Lightning]

[Skills: Unknown]

It was indeed a mutated zombie! David's heart stirred, and he gently moved the spatial blade in his hand, aiming through the open corner, and shot it at the Level 4 zombie! In less than three seconds, the spatial blade pierced through the zombie's forehead. A glowing crystal dropped from its forehead. The spatial blade instantly took the life of the Level 4 zombie!

Impressive! David was amazed. Just as he was about to pick up the lightning crystal, a confused zombie walked towards it. It picked up the crystal from the ground and held it in its hand!

What's this? David's gaze followed the zombie. The zombie kept walking forward and disappeared into an alley, out of David's sight.

In the room, Sally felt a chill all over her body. She sat up from the bed, gasping for breath as she looked around. She had been having a suffocating dream, and since the apocalypse, she only felt at ease when she slept with David. She lay back down, but as soon as she closed her eyes, all she could see were zombie faces.

Unable to sleep, Sally reluctantly sat up. She looked around the dark room and felt a sense of emptiness. A pair of slippers was placed by the bed, but she didn't put them on. Instead, she stepped on the floor directly. She touched the wall and walked out slowly. David had pulled open a corner of the curtains, allowing a beam of light to enter.

"David?" Sally spoke softly.

David heard the voice and turned his head. He closed the curtains and walked towards Sally. "Why are you awake?"

As he spoke, David embraced Sally, and Sally gently held onto his back, resting her chin on his shoulder, taking a deep breath. Suddenly, Sally felt something and exclaimed, "You've leveled up?"

David smiled faintly and released Sally from his embrace. He nodded. "Just now, I reached level four." Sally's face showed a hint of regret. In the short time she slept, David had surpassed her by one level. After hesitating for a moment, Sally reached out her hand to David. "David, I think I can do it too."

David paused for a moment, then took out ten crystals from the space and placed them in her hand. "Take it step by step," David advised.

Sally tightly gripped the ten crystals and walked back into the room. She had to become stronger so as not to burden David.

Meanwhile, in CJ City, inside a rented house, a woman stood in high heels. Her face was heavily made up, and she wore professional attire with the top buttons undone, revealing a glimpse of the undergarment. She stood by the window, holding a cigarette between two fingers, exhaling smoke rings. "These zombies are changing faster and faster" she said casually, her gaze fixed on the zombies outside the window.

Behind her, a man sat on the sofa, holding the TV remote control and impatiently pressing the buttons as it made a crackling sound. The woman turned around, looked at the man coldly, and said, "This damn TV is broken like this, can't you be quiet?" With disdain in her eyes, she glanced at him and crushed the cigarette butt on the nearby table. She crossed her legs and sat on the edge of the bed.

In the room, a figure slowly emerged from the shadows. He reached out his hand, took the remote control from the man, and placed it aside. "Danny, stop fidgeting. Your sister is already looking down on you."

Danny, as the man was called, was stunned, looking at his empty hand, he sighed. He casually replied, "It's been a week, not watching TV, not knowing what's happening outside. What else can we do? All we do all day is kill these zombies, and our supplies are running low."

Snap! The woman, with her legs crossed, lightly kicked the pile of crystals beside her. Although the room was filled with a small mountain of crystals, they were all low-level ones. Danny glanced in the direction of the sound, meeting the woman's gaze. He helplessly pulled the corners of his mouth, shrugged his shoulders, leaned back on the sofa, and muttered.

"It's just the way it is." The man standing next to Danny patted his shoulder, seeing the awkward atmosphere and quickly spoke, "Don't argue. At this time, we should go out and gather supplies."

The man stretched lazily, yawned, and picked up a small knife from the side. He took the lead and walked out of the room. The woman picked up seven pieces from the bed, lifted her skirt that covered the shoes, and inserted the seven pieces into the slots next to the shoes.

Danny looked at the two of them and sighed helplessly. He packed his belongings while picking up a few crystals from the floor and stuffing them into the backpack he carried on his back. Muttering something under his breath, he walked out of the room. After they left the room, an elderly person sat in a rocking chair and slowly opened their eyes.
