Doomsday: with unlimited warehouse system

David had a thought and decided to park the car. "Beauty, we can't go out right now. You should stay here for a while!" Duke said to Monica.

However, Monica's gaze remained fixed on the red light in the sky. This matter had to be reported to the organization, along with the conversation she overheard in the car.

Slowly, Monica shifted her gaze to David who was standing beside her. This person seemed to know a lot. In the next second, David turned his head and coincidentally met Monica's gaze. Just for a second, David voluntarily averted his eyes and took the first step up the stairs.

"Beauty?" Duke extended his hand and waved it in front of Monica. Monica looked at him calmly and nodded. Just as David had said, if they were to go out at this moment, they would turn into zombies. So, she could only stay here for now.

As David went upstairs, before reaching the top, a man slowly descended the stairs. The man had dark circles around his eyes, bloodshot eyes, an unshaven face, and looked exhausted. Surprisingly, David lived on the same floor as this person, yet he had no recollection of him. They exchanged a glance and then both averted their eyes.

The man passed by Duke and the others. Duke glanced at the man and asked David, "How come I didn't know that there are other people besides us in this building?"

David nodded but didn't pay further attention to Duke's words. However, Duke's next statement reminded him again. "But wait, didn't you say that after the red light shines on us, we all turn into zombies? That guy doesn't seem to be affected at all!"

"Not affected?" David turned his head in surprise.

Duke nodded and pointed in the direction the man had left. "I saw him walk into it." David quickly ran to the corridor and looked outside, just as Duke had described. The man from earlier was walking under the red light without undergoing any changes. It was as if the red light had no effect on him at all. This was a situation David had never encountered before.

Who exactly was that man? David rubbed his temples, feeling a headache coming on. Due to Duke's proactive nature, he wanted to take Monica back to his room to protect her. In the end, David entrusted Monica to Sophie, instructing Arnold and Sophie to take good care of their distinguished guest. Before Duke left, he gave David an annoyed glare, as if David had interrupted his romantic endeavors.

David chuckled helplessly and instructed everyone not to leave the house until the red light subsided.

Returning home, as soon as David stepped inside, he didn't see Sally's figure. It was only when he entered the room that he saw her. Seeing Sally lying on the bed, he realized something at that moment. His heart tightened suddenly, and he quickly turned around.

"What?" David flipped Sally over, and her forehead was covered in dense cold sweat, even soaking her clothes. Beside Sally, a few crystals lay quietly on the bed. Combining the crystals with Sally's appearance, David figured out most of what was happening.

Everyone had a limit to how much they could absorb, and Sally was breaking through that limit! David took a tissue and carefully wiped the cold sweat off her forehead. Gently laying Sally back down, he held her hand and stood guard by her bedside.

After an uncertain amount of time, despite the strange sky outside, the room remained shrouded in darkness behind the curtains, with the view unchanged.

Sally slowly opened her eyes and, upon waking up, looked at the ceiling, unable to distinguish whether it was day or night. She was about to move when she noticed someone by her bedside.

David tightly held her hand and, sensing her movement, opened his eyes. "Awake?" he asked.

Sally looked at him, a bit confused. "You're back?"

David nodded and approached her, embracing her tightly. "Breaking through the limit is very dangerous. You were too reckless." Hearing David's words, Sally smiled and hugged him back. "I think it's worth it. I just wanted to try."

As the words fell, David released her and had a displeased expression on his face. "It's too dangerous. Don't do something like this again."

If she had failed in breaking through, what David would be holding might have been a lifeless body. Sally's heart warmed at David's gaze.

"You were worried about me?" Sally leaned closer, playfully asking.

David playfully tapped her nose and said, "I was scolding you."

As Sally smiled, she quickly planted a kiss on David's lips. "Consider it a reward for your concern."

David looked at her, momentarily stunned. He licked his lips that had just been kissed and then hugged Sally tightly again. The two of them fell onto the bed together.

After three hours of intimate connection, David, shirtless, looked at Sally, who had fallen asleep. He gently kissed her forehead and considerately covered her with a blanket before leaving the room.

David sat on the couch, and with a thought, he took out forty primary crystals from space. He looked at the forty crystals shimmering before him.

Without hesitation, David consumed all of them in one breath. He covered his chest and fell to the ground in pain. After about half an hour, David slowly stood up from the floor. Having absorbed all forty crystals, he instantly felt refreshed and clear-headed. However, there seemed to be no sense of fatigue.

Could it be... David's eyes lit up, and he took out ten more crystals. Looking at the crystals, he swallowed his saliva. Each additional crystal he consumed carried an element of risk. If he made a mistake, when Sally woke up, she would see a lifeless body.

With these thoughts in mind, David picked up the first crystal and began absorbing it. After finishing one, he felt no discomfort at all. David felt delighted and continued to absorb the remaining crystals. "The tenth one."

Looking at the last crystal in his hand, David gritted his teeth and absorbed it. Suddenly, his eyes widened, and his body made a loud noise.

Thump! His heart suddenly trembled! David clutched his chest and fell to his knees. "Hoo... hoo." He gasped for breath, mouth wide open, taking in large gulps of air. Drip! Sweat dripped from his forehead onto the floor.

In the room, the sound of David's heavy breathing could be heard clearly. At this moment, his heart rate began to accelerate. Thump, thump—the sound of his heart echoed in David's ears, unusually clear and alert.

Suddenly, David's heart tightened, as if a needle had pricked it. He bit his lip, suppressing any sound, and naturally fell to the ground.
