"Don't worry, young lady. I will definitely try my best to help you find your relatives during this period. Just treat me as an elder. Is that ok with you?"

After hearing Zhou Fuhai's explanation, Murong Chunrui breathed a sigh of relief and nodded to show that she believed them, but she still held the branch in her hand.

"Okay, thank you for your help then."

After settling Murong Chunrui down, Lin Tian returned to human form.

"What exactly is a crystal core? The creatures over there give me a weird feeling..."

As he spoke, Lin Tian took out a crystal core from his storage ring. Under the moonlight, the crystal core emitted a strange light, as if it was collecting moonlight.

He subconsciously touched the crystal core that Lin Tian had given him before in his arms. It was still there, which meant that Lin Tian had gotten more than one.

Thinking of this, Zhou Fuhai stopped his unnatural movements and expressions and looked apologetic.

It’s not that he didn’t trust Lin Tian, ​​but the crystal core was too important to them.

In Lin Tian's eyes, this was natural human nature. He glanced at Zhou Fuhai and continued speaking.

"I won't secretly take back things I give away, so don't worry. If you need more, I can get them, but you have to tell me what they are for."

Lin Tian threw the crystal core in his hand to Zhou Fuhai as a reward for him telling him the relevant information, then leaned against the wall and closed his eyes.

Zhou Fuhai didn't hesitate, he put it in his arms, organized his words a little, and opened his mouth.

"You just mentioned it, biological, right?"

With his eyebrows slightly wrinkled, Lin Tian opened his eyes and looked at Zhou Fuhai. He found things becoming more and more interesting.

Although he once sat on the position of the Demon Emperor, his vision was still too narrow, limited to the small area of ​​the imperial capital.

If it weren't for this opportunity of reincarnation, he might never have the chance to come into contact with these things.

This world is indeed more exciting than before. Only through constant experience can we become stronger and able to deal with different crises.

Thinking of this, Lin Tian's gaze fell on a mountain next to him. The back of this mountain was where crystal cores were abundant.

"Those things didn't exist originally. It was as if they fell from the sky, causing us heavy casualties."

Those creatures are not aggressive when they first appear, but at night they will expose their crystal cores to the air.

It is particularly dazzling under the moonlight, and it is obviously a priceless treasure like a night pearl.

Therefore, it attracted the attention of many villagers.

It was okay when there were fewer people, and almost everyone could benefit from it, but later the output became less and less, and the villagers would fight over it.

"Until one day, the fight got out of hand and one person was accidentally pushed down by the other, and he hit his head on the stone wall and died."

Naturally, after this incident, the villagers calmed down and the man's body was hastily buried.

“The weird things started from this day.”

From then on, those things became restless as if they had tasted human blood.

Occasionally, there are people who go to collect crystal cores, and they become their food.

"So how did you discover the use of the crystal core?"

"This is what I want to tell you. You may not believe it, but when we look up at the sky through our eyes, strange words appear on the crystal cores."

"Strange text?"

As he spoke, Lin Tian took out another crystal core and looked at it towards the moonlight. This action made Zhou Fuhai swallow his saliva.

How much does this guy have?

It’s really good to have strength. They had to work so hard to get one, but others used at least three easily.

Through the moonlight, Lin Tian saw nothing.

Then he injected spiritual energy into it, just like controlling a weapon, and sure enough, strange words appeared on it.

After looking at it carefully, Lin Tian thought that this was an ancient martial art, but it has been lost until now.

Recording the above content in his mind, Lin Tian didn't think about practicing or trying it.

Taking out a dagger from the storage ring, Lin Tian tried to embed the crystal core on the dagger.

Then a magical thing happened. The dagger began to emit a wonderful light. Lin Tian could feel that the quality of the dagger had improved by at least one level.

"This material is indeed top-quality for refining equipment."

As he spoke, Lin Tian waved his hand and a sword wave shot out, instantly shattering the rock.

"You come and try, attack me."

Zhou Fuhai was stunned, but still took the dagger handed over by Lin Tian. A hunter would naturally know how to use this thing.

He looked at Lin Tian again, and seeing the other party's expression indicating that he should attack, he adjusted his movements and swung directly towards Lin Tian.

When using the dagger, Zhou Fuhai felt his body was extremely light, and even a kind of true energy was flowing in his body, as if he was a dozen years younger.

The move was launched at an extremely fast speed. Zhou Fuhai knew very well that this must be the result brought about by this crystal core.

Excited, Zhou Fuhai thrust out a sword as fast as lightning. The tip of the sword cut through the void and went straight for Lin Tian's throat.

"What a fast sword!"

Lin Tian's expression remained unchanged, instead he was observing Zhou Fuhai's actions.

He easily blocked all of Zhou Fuhai's attacks, then Lin Tian suddenly stretched out his right hand and grabbed Zhou Fuhai's wrist.

Twisting hard, Zhou Fuhai suddenly felt a huge force coming at him. He couldn't help but take two steps back, but finally he stood firm.

Looking at Lin Tian, ​​Zhou Fuhai gave him an expression of admiration. He knew that he could not beat Lin Tian at all, and what Lin Tian had just done was so easy, just like a piece of cake.

"Please enlighten me!"

Zhou Fuhai bowed towards Lin Tian, ​​put away the dagger and handed it back to Lin Tian.

Although the method of using the crystal core is similar to that of himself and others, the effect it brings is completely different.

"May I ask how you did that?"

"Do you want to know?"

Looking at Zhou Fuhai's eyes full of expectation, Lin Tian shook his head and then said something extremely hurtful.

"Only monks can do this. For ordinary people like you, it's already great to be able to use it."

"Are you a monk, sir?"

Nodding, Lin Tian did not deny it, but he saw a hint of doubt in Zhou Fuhai's eyes.

After hesitating for a long time, Zhou Fuhai finally asked.

"Just now I saw you turned into a butterfly. If I'm not mistaken, you should be a butterfly spirit, right?"

Lin Tian was also stunned when he heard this. How should he explain to him what happened to him? It was totally inaccurate to say that he was a butterfly spirit. To some extent, he should still have a human body, but he could only transform into the appearance of a butterfly.
