Doomsday: with unlimited warehouse system

David drove towards the location of the cold storage. A cat and a dog sat in the back seat, with Cola dozing off and Little Black constantly looking out through the window.

Little Black was curious about everything outside the window. Whenever it saw zombies chasing vehicles, it would let out an alerting bark and desperately scratch at the window. It seemed like it wanted to go down and fight those zombies.

With a cat and a dog in the car, David felt a sense of balance. Having both a cat and a dog was the goal of many people's aspirations. David looked at Cola through the rearview mirror and asked, "By the way, Cola, what ability do you have?"

"Meow?" Due to the language barrier, David's attempt to have a conversation with the cat failed. But he was genuinely curious about what abilities Cola possessed. Although he knew that Little Black was undoubtedly a powerful mutant beast, Cola had only demonstrated extraordinary speed so far.

"Could it be physical enhancement?" Judging from Cola's speed, it seemed to lean towards physical mutation. With its agility alone, it could already defeat most Level 1 esper. That was why David brought it along. Many mutant beasts were not inferior in strength to espers.

In the apocalypse, humans were not the favored side. About an hour later, David arrived at the industrial park again, this time without using navigation and found the location of the cold storage with ease.

David parked the car next to Warehouse No. 1. As soon as he opened the car door, Little Black burst out like an untamed wild horse and frolicked in the open space. However, it quickly stopped and alertly sniffed in the direction of Warehouse No. 1, clearly sensing something unusual.

Little Black suddenly barked a few times towards Warehouse No. 1 and then looked at David, as if giving a warning.

Cola also jumped out of the car and looked towards the location of Warehouse No. 1, its gaze vigilant. David noticed all the reactions of Little Black and Cola. "Mutant beasts are indeed sensitive. They've detected abnormalities so quickly."

He waved at Little Black and Cola. "Follow me." Cola obediently followed behind David, and Little Black stopped its playful antics and walked beside David, its eyes fixed on the direction of the room temperature warehouse.

David led the cat and the dog to the entrance of the room temperature warehouse. Little Black barked even louder this time, looking excited and agitated, staring at the rolling shutter door inside.

David lifted the rolling shutter door, and the warehouse was filled with mutant rats once again. As the sunlight streamed into the warehouse, the mutant rats instantly became frenzied. Especially when they saw Cola and Little Black, they regarded them as formidable enemies. The mutant rats squealed loudly and launched a direct attack, rushing towards David like a black tide.

"Go, Little Black, Cola, show me your strength." After hearing David's command, Little Black became extremely excited and took the lead to charge out.

"Silly dog, don't get surrounded. Use your fire breath, why are you charging in?" David felt helpless. No wonder they say that dogs meddle in the affairs of mice. Little Black's enthusiasm for catching rats was even higher than that of a cat.

Little Black had originally planned to charge into the group of rats, but after hearing David's words, it calmed down. It stopped not far from the front of the rat group and spewed a green flame towards the mutated rats, instantly engulfing the leading troops of the rats in flames. When the fire dissipated, it turned out that hundreds of rats had been burned to white bones, demonstrating the terrifying power of this green flame.

David was also amazed at this scene. No wonder Adolf became the top-ranked esper in the SJ City Rankings with just a dog in the previous life. The power of this green flame was indeed a bit exaggerated, instantly incinerating the flesh and blood of the rats.

In the previous life, David had heard that the flames from Little Black had a special burning effect on flesh and blood. Once it touched a bit, it would spread throughout the body. Unless the flesh and blood were completely incinerated, the flames would not extinguish.

Because of the characteristics of Little Black's flames, many powerful espers died miserably under its flames. It was said that only one esper survived after being hit by small black's flames. In order to prevent the flames from spreading throughout his body, he severed his left hand, thus saving his life.

After small black spewed out a flame and killed the rats, its wild nature seemed to awaken. It ran excitedly, keeping a distance from the rat swarm while continuously spewing flames. With each flame, dozens or even hundreds of rats were burned to ashes.

On the other hand, Cola, seeing small black's performance, didn't want to be outdone. It also charged out, moving as fast as lightning. Just as David thought it was going to engage in close combat, he discovered a fluctuation of energy emanating from Cola. As an esper, David was extremely familiar with energy fluctuations, and this was a precursor to releasing esper abilities.

Cola summoned several dark shadows, which fell onto the rats, enveloping them like a black mist. Although these shadows had no attacking power, they completely blocked their vision. The rats were suddenly plunged into darkness and couldn't see anything. They became a group of headless flies, panicking and running amok in the warehouse, occasionally bumping into obstacles around them.

Coca-Cola charged into the group of blinded rats, like a tiger among sheep, starting a one-sided slaughter. Its claws were extremely sharp, comparable to swords. With each swipe of its claws, a rat would meet its end. Some rats tried to attack Cola by relying on their sense of smell. However, Cola was too fast, and all their attacks missed, posing no threat to it. David looked on with a surprised expression.

"Shadow-type esper?" Shadow-type espers were almost as rare as spatial-type espers. Unexpectedly, Cola possessed this kind of ability. He had heard that shadow-type espers were always elusive and had extremely mysterious attack methods, making them a difficult type of esper to deal with.

Watching Cola kill in the midst of the rat swarm, David suddenly remembered something from the previous life. He had heard about a famous "Shadow Cat Demon" in a large base in City D. The entire base provided it with delicious food and drink, fearing to upset it. This "Shadow Cat Demon" was the most powerful presence in the entire base. Moreover, this City D was located right next to SJ City.

"Could that Shadow Cat Demon be Cola?" Just as David was surprised, the cat and dog had already gone berserk in the rat swarm. Within just two or three minutes, several hundred rats had already died at their hands. David watched with a sense of satisfaction. They were much more efficient than he was.

"Indeed, you two are professionals when it comes to catching rats."
