The end of the world: With unlimited supplies, I can fly

In the past few days, Li Xin'er not only did nothing in the base, eating melons everywhere, but also occasionally went out to 'hunt' and found 20 level 1 crystal nuclei.

Including the 4 level 1 crystal nuclei she had left that had been purified, there were 24 in total.

But halfway through, he used two more for experiments and dealt with the remaining two people in the space.

Li Xin'er now has 22 level 1 crystal cores in his hand, 19 of which have not been purified.

Li Xin'er took out one that had not been purified, placed it on the table, and handed it back to Lu Chen.

"Ever seen this?"

The moment Lu Chen saw the crystal core, his pupils suddenly shrank, and then he pretended not to know anything about it, and reached out to pick it up in confusion.

"What is this? Crystal?"

The upper management established a secret laboratory for research as early as the day the apocalypse broke out. From the zombie virus at the beginning to the superpowers later, they gradually explored this unknown mystery.

As for the three Lu brothers, there are no secrets about this laboratory.

Lu Chen has seen this kind of stone and knows its origin, but the laboratory has made no progress in its detailed information.

Since Li Xin'er took out this stone at this time, he must know something.

Lu Chen reacted very quickly and controlled his expression perfectly, but what made Li Xiner not a normal person at all?

Even the smallest changes, if she pays special attention in advance, don't try to avoid her eyes.

"This is the crystal core, the thing inside the head of a level 1 zombie."

Her tone was light, as if she was talking about something unimportant.

Now that she decided to do this business, she had no intention of hiding the existence of the crystal core.

Of course, it just exists. As for the rest?

She won't remind them, nor will she stop them from discovering.

Lu Chen looked surprised. He wasn't pretending this time. He was really surprised. He didn't expect that this thing had a name, crystal core?

Li Xin'er didn't give him a chance to ask more questions and continued:

"This crystal core is quite rare now, because it only exists in the heads of level 1 zombies, but in the future, zombies will be fully upgraded, and the crystal core will no longer be scarce."

She tapped her fingers lightly on the glass of the table, and the sound was crisp. Along with her words, the sounds violently impacted Lu Chen's heart.

"And what I want are these crystal nuclei. I have supplies, and you have people. Exchange them for crystal nuclei. Again, anything, no limit to the quantity."

Lu Chen was deeply shocked at this moment. The amount of information revealed by Li Xin'er was too large to be consumed at the moment. He asked:

"You need these nuclei..."

What to do? In other words, what is the use of this crystal core?

Li Xin'er shook his head, "You don't need to know this, but I can tell you very clearly that it will not harm you or anyone else in the world."

At this time, there was no need for Lu Chen to continue asking. Li Xiner took the initiative to explain some related questions.

"You can still continue to study the crystal core. I will not interfere with it. There is only a transactional relationship between us."

Lu Chen knew that Li Xin'er now had the initiative, and their position was very passive. Not only could they not act rashly, but they also had to be cautious in their words and actions.

He followed Li Xin'er's words and without asking any more questions about the crystal core, he said:

"Then can you reveal more about the zombie upgrades you mentioned?"

Regarding these, Li Xin'er had no intention of hiding anything when she thought of cooperating with the country.

Before, she had thought about dragging down the world's laws of heaven and letting the world be destroyed.

But... since she confirmed her inner feelings, she no longer struggled with who she was, she was still the same Xin'er.

Just have fun in this world and experience a different life. By the way, you can unlock the third floor of the root tower and leave.

Since this is a place for her to play, there is no need to destroy it. As long as everyone is kind and she helps, everyone will benefit from each other.

Li Xin'er opened her mouth to answer his question,

"The zombies will not only reach level 1, but will also evolve to higher levels later. Zombies of different levels have different characteristics. In short, they will gradually become stronger."

When Lu Chen heard this, he frowned and looked ugly.

This is already quite serious for human beings. Do you want to upgrade? So is there still a way for humans to survive?

Li Xin'er saw his worries and immediately added a reminder,

"Don't worry too much. When zombies upgrade, the same superpowers will also upgrade. I believe you have studied a lot of superpowers. You don't need me to say more, right? For example, various superpowers?"

Lu Chen avoided the question they were researching and asked sharply:

"How to upgrade?"

It didn’t explain whether the zombies were superpowers, so the answer depended on Li Xin’er’s mood.

Li Xiner leaned back, crossed her arms with her chest and stared at Lu Chen, saying angrily:

"Are you Lu family members so thoughtful?"

Lu Chen knew that she was referring to Lu Jin'an's test outside the door just now, and smiled awkwardly.

"I'm used to it in business, sorry."

Li Xin'er just complained casually, not wanting to get entangled in this matter, and said instead:

“Zombies rely on devouring and time. Simply put, the more they eat, the faster they evolve.

People with superpowers rely on fighting, which is why they level up in the game by defeating monsters. "

Lu Chen nodded and remembered every word in his heart.

Although he doesn't know whether these things are true or false, he currently subconsciously believes in Li Xin'er, and time will answer everything.

He asked tentatively: "How do you know this?"

Lu Chen was not sure whether Li Xin'er would answer, but he had to try this question.

Li Xin'er raised her eyebrows slightly, put her right elbow on the table, supported her chin with her hand, and answered the question.

"Instead of talking here, it's better to take action. You can report it to the superiors and let's try to conduct a transaction first."

"You give me a list of supplies, and I'll determine the number of crystal cores. If I'm satisfied, I'll close the deal. However, for this first transaction, I need to add a condition."

Li Xin'er's words were just as Lu Chen meant. They couldn't just listen to Li Xin'er's empty words, they had to see something real.

Hearing that there was an additional condition, Lu Chen also became cautious, "What condition?"

"I'm still focused on my sister's identity. Since I'm officially cooperating with you, how about solving the identity problem?"

Lu Chen was surprised, "You?!"

So it's a split personality? Mental illness? Or is it true and there is another secret behind it?

Before, Lu Chen always thought that she just liked that title, so he specially cooperated and called her Miss Xin.

Now at this moment, Lu Chen was panicking again.

His reputation will not be ruined by a mentally ill person, right?

Li Xin'er stared at Lu Chen and raised her eyebrows slightly, half-smiling but not smiling:

"I told you that she and I are two people, don't get confused."

In Lu Chen's opinion, this expression was a bit eye-catching...

"Then... what about Li Xin'er?"

Li Xin'er shrugged his shoulders and said indifferently:

"Just think of her as dead."

Anyway, she can't come back. In this world, in these people's world, there is no difference from death.
