Doomsday: with unlimited warehouse system

A primary crystal dropped to the ground , The doctor looked at the milky white crystal on the floor, feeling confused. "What... What is this?" he trembled and asked.

David responded calmly, "If you want to come along, eat this."

"Eat... Eat this?!" The doctor was surprised, but he dared not speak too loudly, restraining his voice.

David silently looked at him. The doctor had no choice. He had no companions here, and outside were all zombies. If he didn't eat the crystal, he would be eaten by the zombies outside.

Looking at the crystal on the ground, the doctor swallowed his saliva and reluctantly picked it up. "If I eat this, can I go with you?" he asked tentatively. He was not stupid; he could tell that these two intruders had the ability to protect him. As long as he clung to their legs, he wouldn't have to worry about surviving in this environment. And they must have food!

The doctor gritted his teeth and quickly consumed the primary crystal in his hand. Gulp. The crystal went into his stomach, and he expected something to happen. However, after a minute passed, he didn't feel anything unusual.

The doctor's eyes lit up, and he immediately started laughing. Excitedly, he said to David, "Hahaha, I... I'm fine. Can I go with you now?"

David looked at the doctor and sighed silently. "What a waste of my crystal." As he spoke, a spatial blade appeared in David's hand.

"What are you doing? You can't go back on your word!" The doctor looked at the item in David's hand, showing a fearful expression. Just as he was about to run away, he suddenly realized that his vision became extremely strange.David's figure in front of him became extremely blurry, and then his hands, feet, and his entire body started losing control.

The next moment, he let out a roar that didn't belong to him. David looked at the zombie in front of him, swiftly decapitating it, rendering it motionless. He squatted in front of the zombie and lightly cut open its forehead, taking out a primary crystal. "Not everyone is lucky."

[You obtained a primary crystal, critical hit of 100,000 in effect!]

[Congratulations, you obtained 100,000 primary crystals!]

After completing everything, David walked out. After a few steps, he encountered Arnold who was coming back. Arnold had made a good harvest, with his backpack filled to the brim. Once they returned and stored everything in the space, they would have a substantial amount of supplies. Arnold looked at David, noticing there was no one else behind him, and understood everything without saying a word.

"Let's go," David said, leading the way. He looked at the zombies on the ground, which suddenly stopped moving.

David slapped his head and turned to Arnold. "Open their foreheads and take out the crystals."

As he spoke, David squatted down and skillfully took out one crystal after another. Arnold was slightly stunned, looking at the numerous zombies on the ground, and followed David's lead. In no time, the two of them collected nearly a hundred crystals. David looked at the crystals on the ground, and with a thought, all the crystals entered the space.

"David, are we pick up leaks?" Arnold looked at David's actions, slightly surprised.

[You obtained 98 primary crystals, critical hit of 100,000 in effect!]

[Congratulations, you obtained 11,800,000 primary crystals!]

Listening to the system prompts one after another, David felt very satisfied. This trip was definitely worth it! At this rate, whether it was for himself, Sally, or Little Black Cola, leveling up rapidly was just a matter of a few clicks.

With these thoughts in mind, David took out a crystal from his hand and threw it to Little Black beside him. Little Black lightly jumped and bit down on the crystal that David threw, swallowing it.

David watched as Little Black consumed it and felt satisfied. Currently, as long as Little Black and Cola didn't eat too many crystals, they could absorb them without needing to sleep. Bringing them along while leveling up was a perfect solution.

Outside the hospital, David could see many zombies heading towards a small shop. But strangely, once these zombies entered the shop, they never came out again. Moreover, there was a strong stench of decay permeating the air. These zombies seemed to be different from them; they walked straight ahead without any hesitation.

Taking advantage of this opportunity, David led Arnold and Little Black into a nearby general store. It was evident that the store had already been looted, with empty shelves and a few of them even collapsed on the ground. The whole store looked extremely messy.

"David, what is this..." Arnold started to speak, but David had already walked in. Since these people had looted things in the chaos, they couldn't return empty-handed now. The two of them, along with the dog, continuously moved around the store, not even leaving out the tiniest corners. Finally, they found a few abandoned candles in a small corner behind the counter.

"David, just a few candles," Arnold held up the candles in his hand, feeling helpless.

Although it was just a few, in David's hands, with a critical hit of 100,000, these candles were no longer just a few.

Without saying a word, David directly took the candles from Arnold's hand. With a thought, he stored the candles in the space.

[You obtained 5 candles, critical hit of 100,000 in effect!]

[Congratulations, you obtained 500,000 candles!]

Listening to the system prompts, David nodded satisfactorily. Candles were still very useful under certain circumstances.

Looking at the empty store, David led Arnold and Little Black out. But just as they stepped out of the store's entrance, David suddenly stopped.

"David, should we go back inside the store?" Arnold whispered, slowly stepping backward.

In front of them, the zombies that should have been heading towards that store all turned to look in David and the others' direction.

David calmly summoned his armor and looked at the approaching zombies. There weren't many of them, so dealing with them was no problem. David clenched his fist and flexed his muscles.

"Don't panic, let's go!" Fortunately, the number was not large. Once the numbers increased, it would be really difficult to deal with them. As soon as he finished speaking, David charged forward with the spatial blade in his hand!

"David is so fierce!" Arnold looked at David charging forward and was momentarily stunned. The next moment, Arnold shouted, "David, I'm coming too!"

Little Black barked and followed Arnold, charging forward as well. The flames it spewed instantly incinerated a large number of zombies. Fortunately, they were all low-level zombies, so this number wasn't enough to pose a threat. In no time, David, Arnold, and Little Black had taken care of all the zombies.
