"Well, what's wrong?" Shen Ran frowned slightly.

Zhang Yue didn't answer him, but at this time, she had an extra dagger in her hand, walked past him and walked towards the zombie that fell to the ground, walked to the place where it was headed, squatted down, and then pierced the dagger to the place where Shen Ran smashed it and stirred it again, and after a while, something like a bead rolled out of it.

It was still raining, and the beads rolled out and were quickly washed clean to reveal their true colors.

Zhang Yue didn't reply to his words, he didn't get angry, but followed curiously, and after seeing the bead, he asked, "What is this?" ”

"This thing is a crystal nucleus, which contains an energy that can make zombies stronger, and it can also allow the ability to recover energy, or use it to increase their ability level." Zhang Yue replied

"Can you level up your abilities?" Shen Ran looked at her in surprise.

Zhang Yue nodded and explained: "But this thing is grown from the zombie's head, and even if there is some energy in it, it contains a little virus ingredient, and it is not pure." If you use it to increase your level, your strength will be reduced by 20%, which is not as strong as naturally rising. “

"At the beginning, I couldn't see anything, but after a long time, after everyone's level was raised, the strength of those who were promoted with crystal nuclei may not even be able to beat those who are three levels lower than him. So, it's good that this thing is used to restore energy, and it's better not to think about leveling up. ”

"I see."

When he heard her say that it could be used to improve the level just now, he was still thinking about whether to try it, and after hearing her say this, this idea was immediately cut off.

"Does this thing have all the zombie heads?"

Zhang Yue shook his head, "At the beginning of the end of the world, there were no ordinary zombies, only mutated zombies. After a long time, there will be individual and mutated zombies after the ordinary zombie level is raised to the first order. ”

"Oh, how did you know that?"

At this time, the rain had become smaller, and Shen Ran stared at her with his deep eyes, not suspicious of anything, just curiosity and doubt.

These are things she has experienced and seen in her previous life, but Zhang Yue can't say it, but she is not worried about the question he asked.

She pursed her lips and smiled, and replied, "You soldiers don't read online novels, they are all written in these novels." I didn't believe in these before, but now that I have the end of the world, I wanted to try it, but I didn't expect one to be dug up by me. In this case, the role of the crystal nucleus written in the novel is not unreasonable, after all, there are advantages and disadvantages. “

"If the supernatural who only uses the crystal nucleus to ascend is also very strong, then the person who knows this first desperately raises his level, and when no one is invincible, if he is an upright person, if he is an ambitious and brutal person, won't this world become an even more cruel eighteen purgatory than now?"

This is very reasonable, Shen Ran nodded after listening to this explanation, and did not continue to ask this question again. He just said: "Then you can put it away, it's been raining for so long, hurry back and take a shower, don't really catch a cold for a while." ”

As she spoke, she held out her hand to him.

This time Zhang Yue didn't postpone it any longer, picked up the crystal nucleus and retracted the space, since she looked at Shen Ran's space, she found that her small space was not enough for him to see at all, so now she didn't bother to hide it in front of him.

After putting away the crystal nucleus, he put his hand on his hand and let his large, warm hands lead him back.
