Doomsday: with unlimited warehouse system

With Cola's extraordinary form revealed, David gained greater confidence in surviving in this world. Moreover, with little black awakening as a Lord-level familiar, he believed that it wouldn't be long before it could grow into a super familiar on par with Cola.

Upon returning to the new base, it was already completely dark. After parking the off-road vehicle, David carried little black and Cola to the entrance. "Knock, knock!"

"Slogan!"

"Newborn."

The security door instantly opened, and Arnold stuck his head out, looking at David with some concern. "David, where were you? Why did you come back so late? Everyone was getting worried." As the core of the team, David was the backbone of everyone. So when they saw the sky turning dark and David hadn't returned yet, everyone was anxious, fearing that he had encountered some danger outside. Even Arnold was about to go out and look for David, but Sally stopped her, saying that they should trust David's strength. Arnold could only pace anxiously inside the house, waiting for David, and everyone in the living room breathed a sigh of relief when they saw David return unharmed.

"Did you encounter any danger?" Sally asked quickly, noticing David's slightly disheveled appearance. She spoke with concern while examining him, her eyes filled with worry.

David smiled slightly and shook his head. "No, I just took little black and Cola out for a walk. I also wanted to test the power of little black as a Lord-level Hellhound."

David didn't mention the encounter with the intelligent zombie today. He didn't want to worry everyone excessively, which could affect his own level advancement. After all, this was a crucial moment for them to level up, especially Sophie and Arnold. Sophie had just become an esper, and Arnold had just mastered the ability to transform into a werewolf. If they were distracted, it could undermine their progress. Hearing David's explanation, Sally nodded in agreement.

"By the way, how is Duke?" David suddenly remembered Duke, who had fainted due to excessive crystal consumption.

"He's much better now. With Sophie's Stellar Healing, he's no longer in any serious condition. He's probably sleeping now."

David nodded. Although Duke was too eager for quick progress and pursued power excessively, his team currently needed more manpower, and David didn't want to go out and search for new members at this time.

After discussing some other matters with everyone, David returned to his bedroom. He initially wanted to reinforce the defense system of the new base tonight. However, considering that with the appearance of the second red light, there would likely be more formidable opponents like the intelligent zombies, they might become busier. Resting became the most important thing at this time. If he didn't rest well, his combat effectiveness would naturally decrease. He didn't want to die miserably at the hands of zombies due to exhaustion. So without overthinking, he quickly freshened up and fell into a deep sleep as he collapsed onto the bed.

At this moment, Cola squatted at the bedside, slowly opening its eyes. As soon as its eyes opened, without a second thought, it extended its claws and fiercely scratched little black 's head. Startled, little black instantly woke up with a start, looking around cautiously and even assuming a fighting stance.

But when it saw the disdainful expression on Cola's face, its ears drooped, and its eyes filled with a sense of grievance. Its momentary show of power disappeared. Cola licked its paw lightly, then let out a soft meow towards little black before standing up and walking towards it.

Then, taking advantage of the situation, it lay down on the belly of little Black. Resting its head on the soft belly of little Black, Cola yawned contentedly and closed its eyes.

But this frightened little Black! It was fine when Cola beat it up in front of so many people in the afternoon, but now it was using it as a pillow? This was simply bullying!

Helplessly, little Black had to stay still, even reducing its breathing sounds, afraid of waking up Cola. If it did, it would be subjected to a series of bullying from the evil cat.

On the other side, in a dilapidated building, a voice filled with age and a hint of unwillingness came from a laboratory. "Why! Why is it that I have studied every part of the zombie's body and still cannot grasp the secret of its energy!"

Abraham stood in front of the operating table, holding a surgical knife, looking somewhat helpless at the countless dissected zombie bodies before him. Despite his extensive research, he still couldn't uncover the mystery of their energy. This instantly left him feeling disheartened and depressed.

"Ah! Perhaps it's because I'm getting old and my abilities are not enough. Maybe only someone destined can obtain this secret."

Sighing, Abraham put down the surgical knife in his hand and shook his head. Due to the nature of the zombie bodies, he needed utmost concentration and mental strength during his research.

Furthermore, he needed to possess powerful crystal energy within himself to resonate with the hidden energy within the zombies, in order to unearth this secret. However, now in his eighties, his crystal energy had gradually weakened with age.

Standing in front of the zombies, he couldn't sense any resonance of energy. Shaking his head once again, Abraham took off his lab coat. He glanced at the sky, now filled with stars. Unbeknownst to him, he had been in the laboratory for the entire day.

Thinking about Monica and Danny still being at the base, he realized that further delay might cause them to worry. So, Abraham turned around and left the laboratory. Before leaving, he glanced once more at the zombie bodies in the lab and gently closed the door.

Under the moonlight, Abraham returned to the base. Monica, Danny, and the others had been anxiously waiting for his return. When they saw Abraham walking in, they hurriedly approached him.

"Abraham, where did you go? Are you okay?" Monica was the first to support him and ask.

Abraham smiled gently and said, "I'm fine. I just wanted to get some fresh air but ended up getting lost. It took me quite a while to find my way back based on the terrain."

Upon hearing Abraham's explanation, Danny spoke up, "As long as you're okay. In the future, please let us know before you go out. Otherwise, if something dangerous happens to you, we won't be aware." Abraham naturally understood that they were concerned for his well-being and nodded with a smile.

"Oh, Abraham, there's something we want to discuss with you," Monica paused and then spoke up.

"What's up?" Abraham sat down on the sofa, rubbing his legs which were sore from standing for too long.

"We've talked it over with Danny, and we think we need to acquire some firearms."

"Firearms?" Abraham was puzzled upon hearing Monica's words.
