Doomsday: with unlimited warehouse system

The green liquid slowly dripped from the zombie's arm wound and fell to the ground. David stared at the green liquid for a long time, unable to react immediately.

In the previous world, there were zombies with green liquid, but that was about a month after the disaster. How could the zombies mutate so quickly just on the second day after the disaster?

A roar snapped David back to reality, and he quickly looked up. The zombie's gaping mouth was dangerously close, and he swiftly raised his hand, launching several spatial blades in an instant. Unfortunately, all the spatial blades missed their target.

The speed of this zombie was incredibly fast! David's body moved, his eyes desperately trying to keep up with the agile movements of the zombie. He tightly clenched his fingers, searching for an opportunity to release the spatial blades. The other zombies outside had not yet mutated, and the consequences would be unimaginable if this mutated zombie was released here.

The System's Spatial Critical had only a little over a day left, and collecting the Mutated Crystals from mutated zombies was undoubtedly a great opportunity. David's eyes lit up as he called out to Little Black and Cola. "Little Black, Cola! Attack!" Little Black let out a howl and unleashed flames towards the zombie's figure. The zombie moved quickly, and despite Little Black's intense efforts, its attacks could only chase after the zombie's shadow.

Meanwhile, Cola made a move and instantly appeared in front of the zombie. Without using its special ability, it lunged at the zombie's face, catching it off guard. The zombie never expected Cola to be so fast. In the split second of its astonishment, Little Black's flames were already dangerously close from behind.

Now's the time! Seeing the zombie about to dodge, David didn't hesitate for a moment and flung his spatial blade directly at it. One spatial blade accurately sliced through the zombie's neck, while the rest pierced through its abdomen.

The next second, Little Black's flames covered the zombie perfectly. In just a blink of an eye, a strong smell of burning flesh filled the air, causing David to furrow his brow. Cola managed to reach David's feet a split second before Little Black, leaning against it and emitting a low growl. Little Black, who missed the opportunity by a hair's breadth, looked at the scene with resentment, but didn't dare to approach and could only complain in a resentful tone from a distance.

David lifted Cola and crouched down beside Little Black, rubbing its head. "You both did a great job." Little Black satisfiedly nuzzled David's palm with its head, and its voice became more pleasant. When David put Cola down, it glanced quietly at Little Black.

He walked towards the charred remains of the zombie. On the ground, there was only one green-glowing mutated crystal lying quietly. Not even a trace of the zombie's body or ashes remained.

This zombie was different from the mutated zombies David had encountered before. Although this zombie had mutated, its intelligence was much lower compared to the mutated zombies from the previous world.

One could say it had none at all. David picked up the mutated crystal, and with a thought, the green crystal disappeared from his hand.

[You have obtained one Intermediate Mutated Crystal, Critical Hit Multiplier: 100,000x! ]

[Congratulations! You have obtained 100,000 Mutated Crystals! ]

David heard the notification and felt delighted. This mutated crystal was much larger than the previous ones he had collected. The effect of this intermediate mutated crystal was equivalent to a thousand low-level crystals. Moreover, these colored intermediate crystals, when absorbed by superhumans, had the potential to trigger new abilities. With little time left for the ten thousand-fold critical hit, if he could encounter mutated zombies during this remaining time, it would undoubtedly be a great benefit.

With little time remaining, David approached the shipping container and gently lifted the lid. Upon opening it, he saw a whole box of canned meat, rice, bread, and more in front of him.

With a thought, the entire box of non-perishable food disappeared in the next second. At the same time, the system issued a prompt.

[You obtained 50 cans of fresh meat, ten thousand-fold critical hit in effect! ]

[Congratulations, you obtained 5 million cans of fresh meat! ]

[You obtained 50 pieces of bread, ten thousand-fold critical hit in effect! ]

[Congratulations, you obtained 5 million pieces of bread!]...

The non-perishable storage area was not particularly large, and it didn't take long for David to finish exploring it with Small Black and Cola. He planned to go to the frozen storage area next, where he expected to find more food to fill their stomachs. If lucky, there might be another wave of ten thousand-fold critical hits.

As David and his companions passed by the shipping container where the mutated zombie had stayed before, he glanced inside and unexpectedly saw the corpses of several mutated rats!

"This guy eats mutated rats?" David recoiled in disgust and averted his gaze. In the refrigerated storage area, David easily found two containers of inventory. Looking at the frozen food inside the containers, he wasted no time in collecting them.

Finally, he arrived at the frozen storage area. The doorknob was covered with a thin layer of frost, indicating that the temperature inside was much colder than the refrigerated area. David exerted some force before managing to open the door.

As soon as he opened the door, a cold wind blew in, causing him to shudder involuntarily. Small Black and Cola, following behind him, also sensed the temperature and huddled shivering behind David.

With each step, David felt as if he was walking on ice. Due to the catastrophe, all the personnel in Warehouse No. 1 had perished, and naturally, no one controlled the temperature here. The further he walked, the colder the air in the entire area became. However, the colder it was, the rarer the presence of the mutated rats. These rats, despite being mutated, couldn't withstand the cold temperature.

Small Black couldn't bear it any longer and let out a low growl. David turned to look and couldn't help but smile at the sight of Small Black and Cola trembling. "You two wait for me outside."

Upon hearing this, Small Black and Cola hesitated for a moment. Although they wanted to accompany David, they couldn't endure the temperature inside. In the end, they reluctantly returned the way they came. Even if he left Small Black and Cola outside, David had nothing to worry about. The strength of these two companions was extraordinary.

David continued walking towards the end. The cold in this place was nothing for his physical fitness. When he reached the end, he pushed open a door in front of him. Inside the room, he immediately saw boxes of fruits, vegetables, and a considerable amount of dairy products.

As he was about to leave after clearing the room of food, he caught sight of an inconspicuous medical box in the corner.
