Doomsday: with unlimited warehouse system

After being patted on the Little Black head by David, Little Black ran over to Sally and rubbed against her leg. David had heard that ordinary animals would experience a significant increase in intelligence after awakening as mutant beasts. Little Black indeed seemed much smarter now. It appeared to recognize the close relationship between Sally and David, which was why it tried to please Sally.

Sally felt delighted and crouched down to pat Little Black. "You're such a clever little fellow. It looks like I didn't feed you in vain today." After showing off in front of both of them, Little Black called out to the black cat on the sofa a couple of times, its eyes filled with pride and showiness. However, the black cat paid it no attention.

Seeing that the black cat ignored it, Little Black jumped onto the sofa. It lifted its head and spewed a flame toward the ceiling, seemingly showing off to the black cat. Just as it was flaunting its power, David grabbed its nape and lifted it up. "No more breathing fire inside the house, got it? If you burn down the house, I'll definitely give you a beating."

Little Black seemed to understand David's words and let out a pitiful sound. Sally said to David, "This little one has a huge appetite. I fed it five kilograms of meat today before it got full. I can't believe such a small belly can hold five kilograms of meat."

David replied, "Well, it's normal for mutant beasts to have a big appetite. I'll put more food in the fridge for it in the future and try to keep it well-fed." He wasn't worried about Little Black's large appetite. Even if it ate ten kilograms of meat a day, David could afford to feed it. However, it was somewhat nostalgic to think that Little Black's living conditions as a dog might be better than those of most people. He took out around fifty mutant crystals from his backpack and put them all in Little Black's food bowl.

In the post-apocalyptic world, mutant beasts were not united. Different types of mutant beasts often fought each other. Some mutant beasts would also hunt and kill mutant zombies, with the sole purpose of obtaining the mutant crystals in their brains. These crystals could rapidly enhance their strength.

Upon seeing the crystals in the food bowl, Little Black's eyes sparkled. It vigorously rubbed against David's leg a few times and then rushed to the food bowl without delay, swallowing several mutant crystals whole. David noticed that it stopped after swallowing about thirty crystals. It seemed that like human mutants, there was a limit to the number of crystals they could absorb each day.

After swallowing thirty crystals, Little Black guarded the remaining ones in the food bowl, resembling a miser protecting its treasure. Unexpectedly, the black cat suddenly jumped off the sofa and approached Little Black.

"Coke, what are you up to?" Sally felt worried seeing the black cat seemingly wanting to pick a fight. After all, the current Little Black was a mutant beast. If it sprayed Coke with fire, it would be disastrous. Before she could intervene, Coke suddenly turned into a black shadow, as fast as an arrow, and swiftly passed by Little Black.

David and Sally were instantly amazed. "Such incredible speed!" David considered himself not slow, but the black cat's speed was much faster than his. In the next moment, the black cat had already retreated from Little Black's side and returned to the sofa. Only then did the oblivious Little Black notice that its food bowl was gone. It looked up and saw the bowl under the black cat.

"Woof woof woof!" Little Black became anxious immediately and barked repeatedly at David, sounding completely aggrieved. However, David's attention was focused on the black cat. Only mutated beasts would be interested in mutated crystals; ordinary animals would not react to them. Considering the speed of the black cat earlier, could Cola also be a mutated beast?

David sat down on the sofa and asked the black cat, "Are you also interested in these crystals?" It was unclear if the black cat understood David's words, but instead of eating the mutated crystals in the dog bowl, it walked over to David and rubbed against him with a slightly resentful look in its eyes.

David instantly understood its meaning and took out several dozen mutated crystals from the storage space and placed them next to the black cat. The black cat happily meowed and started purring. It crouched down and picked up the mutated crystals one by one, swallowing them gracefully, with much more elegance than Little Black.

A glimmer of surprise flashed in David's eyes. "So, this black cat is indeed a mutated beast."

Sally was stunned. "Ah? Is Cola also a mutated beast?"

No wonder they didn't realize it before. Cola didn't resemble Little Black at all. Its appearance showed no visible changes, just slightly more robust than before.

David returned the dog bowl to Little Black, and Little Black hurriedly grabbed its own bowl and ran to the corner of the living room, hiding it in the wall corner and protecting it with its body. Then, Little Black yawned and fell asleep right away.

David had heard that after consuming mutated crystals, mutated beasts would absorb energy while sleeping. Looking at Little Black in this state, the energy of the mutated crystals seemed to be taking effect. Even in its sleep, Little Black tightly guarded its bowl. Seeing this, David shook his head.

"This silly dog, can't you see that others despise your bowl?" Although Cola snatched Little Black's bowl, it didn't eat any of the crystals. David speculated that Cola was just jealous and didn't really want to eat the crystals in Little Black's bowl.

However, David was still very happy. Most mutated beasts that had lived with humans for a long time became loyal to their masters after evolving. Unless their owners had treated them poorly or abused them in the past, with their intelligence, they would become even closer to their owners, actively staying by their side and protecting their safety.

Adolf from the previous life was such a lucky example. Now, both of these mutated beasts had a good relationship with David, and they absolutely adored David because he had their favorite mutated crystals. This was truly great news for David...

In Sally's room, in the late night, a sweaty Sally snuggled in David's arms, and David hugged her from behind. After the long ordeal they had just been through, both of them were slightly exhausted, and David felt a wave of drowsiness come over him.

Half-asleep and half-awake, Sally suddenly called out softly, "David."

"Hmm? What's wrong?"

Sally snuggled closer to David, pressing her entire body against his chest. "I feel so lucky to have met you."

David guessed that Sally must have witnessed Zoe's ordeal, which made her appreciate her current situation. If it weren't for David, How will she end up any better than Zoe?

David shook his head and said seriously, "No, it should be said that meeting you is my luck." David wasn't just being polite; he genuinely felt that way. It was only because he had randomly decided to bring Sally along that his team now had an electrokinetic ability user and a mutated beast. Wasn't that lucky enough?

Sally was deeply moved upon hearing David's words. She buried her head in David's embrace, her face filled with a blissful expression of happiness.
