Doomsday: with unlimited warehouse system

"New abilities haven't been discovered, but I'm getting better and better at controlling this lightning," Sally said while playing with the lightning at her fingertips.

"Not bad." David supported his chin with his hand, looking satisfied with Sally. It only took about thirty low-level crystals to control the lightning so smoothly. If she used an intermediate crystal, the consequences would be unimaginable. However, it was a pity that each supernatural ability corresponded to a specific color, and Sally's lightning attribute was represented by the color purple.

The crystals they found today were all green, which was not suitable for Sally to absorb. Even if she absorbed them, it would be like absorbing air, having no effect at all.

Green crystals... If David remembered correctly, those belonged to the healing category. Just like in the previous life, healing abilities and individuals with healing powers were extremely rare. If a team had a healer with supernatural abilities, that team would be almost invincible. The healer would be treated as a treasure, even as a tool.

In the previous life, David had witnessed a healer with supernatural abilities being treated like a slave by an organization, trading crystals for their healing powers. In the end, the healer didn't last long and died.

David had considered adding a healer with supernatural abilities to his team. However, he had never found such a person. If he ever encountered someone like that, he would want to keep them hidden, let alone exposing them to the public eye.

"What are you thinking about?" Sally looked at David, who seemed lost in thought, and walked over to hold his arm.

David shook his head. "Nothing."

With that said, he took out fifty low-grade crystals and handed them to Sally. "Continue absorbing these."

Sally paused for a moment, looking at the fifty crystals in her hand. Just by going out for a while, David could collect so many crystals. How strong was David exactly?

"Okay." Sally immediately agreed and turned back to her room, holding the crystals. She needed to become stronger quickly so that she wouldn't hold David back in battle.

After Sally went back to her room, David squatted down in front of Little Black. He caressed its furry coat and put a few crystals in its dog bowl.

Cola approached stealthily,When Little Black saw the crystals in the dog bowl, before it could feel happy, it noticed Cola's posture and quickly protected its own bowl, staring at Cola with doggy vigilance. Cola glanced at it nonchalantly and then rubbed against David's ankle, making a purring sound.

Looking at the cat and dog's behavior, David smiled helplessly. Having this cat and dog as companions in the world of the apocalypse was not boring. He took out a dozen crystals and handed them to Cola one by one.

Cola happily meowed and started eating. It received more crystals than Little Black, as David wanted to see if Cola was truly the shadow cat demon. Little Black, on the other hand, looked at the amount in its bowl, then glanced at Cola's portion, and reluctantly started eating, feeling unhappy as it lay on the ground.

Several crystals, Cola quickly finished eating them. But David looked at Cola and wondered why it didn't look satisfied after eating.Despite consuming several crystals, Cola showed no reaction whatsoever.

"The demand is really high." David silently commented to himself as he watched Cola rolling on the ground.

He took out twenty crystals again. When Cola saw the crystals, it pounced on them directly. Startled, David exclaimed, and the crystals in his hand scattered on the floor.

"What's wrong?" Sally, inside the room, heard the noise and opened the door with concern. At that moment when the crystals scattered on the ground, Cola moved, and all the crystals had already been eaten by it!

"Such speed." David was dumbfounded watching Cola. He knew Shadow Cat Y??kai was fast, but this speed was so swift that he could barely even see its shadow. The last time he saw Cola's speed, it wasn't this fast. It seems that absorbing those several crystals was indeed very effective.

"Cola!" Sally exclaimed and hurriedly ran up to it, but David stopped her.

On the ground, Cola finished eating the twenty crystals at once, curled up on the ground, emitting a faint white light. It was worrisome because Cola seemed to be in great pain, its whole body trembling slightly.

Cola had been with Sally for quite some time, and seeing this scene, Sally couldn't help but feel worried. David glanced at Cola and comforted Sally, saying, "It's okay, Cola is absorbing the crystals."

After hearing David's words, Sally nodded, and her furrowed brows relaxed. After eating the crystals, Little Black quickly fell asleep. David stayed by Cola's side for a long time, but it still hadn't finished absorbing them. In the latter half of the night, David gave up observing and went back to the room to rest with Sally.

The next day, a loud noise woke David and Sally, who were still resting. Startled, David immediately got up from the bed, swiftly stood by the window, and cautiously peered out with one eye.

A nearby house had been blasted open? This commotion attracted countless zombies in the vicinity. With a single glance, David saw that zombies from a wide range were swaying and heading towards the explosion site.

"This is..." Sally murmured as she looked at the explosion site.

"It's hard to say, maybe it's the work of superhumans," David speculated.

"Help! Is anyone there? Is anyone inside the house?" accompanied by a woman's screams, there was a series of knocking sounds on the door. Sally and David exchanged glances and walked to the door. Through the peephole, David saw a young woman followed by a zombie staggering along.

The woman was pounding on David's door like a lunatic, and the zombie behind her was getting closer and closer. "I know you're inside, please, please open the door and let me in!"

David just silently watched the scene, without making any response. He wasn't a saint, and there was no need to save everyone.Moreover, she was an insignificant person.

Sally remained silent as well, following David. She was learning more and more, especially about human nature. Several minutes passed, and the woman continued to pound on the door frantically. However, the zombie behind her remained motionless, just standing a short distance away, watching the woman's actions.

In the next second, the woman's neck made a cracking sound, and the corners of her mouth curved upwards at an alarming angle, lifting all the way to the position of her cheekbones. Even the skin on her body began to rapidly decay, but not a single piece of flesh fell off. There were even a few pieces of flesh hanging loosely on her body without detaching.

Indeed, she wasn't human. David calmly watched. Just as the woman was about to leave, she turned around and went to knock on Arnold's door again.
