After feeling the meaning of Lu Lie, the first vision automatically shattered and scattered into crystal debris.

Immediately afterwards, the second vision flew in front of Lu Lie.

In a deep cave, Li Yuanheng was lying on the ground, gasping for a while, as if he was seriously injured all over his body. Opposite him, a fire frame was supported, and the flames were squeaking among the dry wood.

At the other end of the cave, an old man picked up a firewood and threw it into the flames. The old man turned his head and revealed a wrinkled face. Time left a dense mark on his face, but it also engraved the light of wisdom into his eyes.

The old man heard Li Yuan's moan and turned around to look at him. But soon, the old man turned his head and focused his attention on the pile of broken paper in front of him.

An old man living at the bottom of the valley below the Mishen City?

The paper heads were like the old man, obviously after a long period of time, all turned yellow and a little black. No matter how gentle the old man's fingers were when touching them, some paper heads were accidentally lit into pieces.

The paper was densely filled with formulas that Lu Lie couldn't understand. Lu Lie adjusted the vision of the Eye of Thousand Realms and looked over in another direction. The paper in front of the old man was also painted with various overlapping figures, including centers, ovals, squares, triangles, and lines of different virtual and real.

On the right side of each piece of paper, there are two words written squarely. And these two words Lu Lie just met, "Que Yin".

The old man used a long branch as a pen and the earth as paper, and directly carved various strange symbols and words on the ground with branches.

"Hey, old man!"

Outside the vision, Li Yuan was weak and irritable.

Lu Lie quickly adjusted his vision and turned his sight to Li Yuan's direction.

Li Yuan supported the earth with his hands and tried hard to get up from the ground. But when he found out that he had failed, he had to lean on the cave helplessly and shouted to the old man: "Since you said that you wanted to leave here, you could leave a long time ago. Why did you have to stay here for hundreds of years?

"There are no family and friends under your tree. Are you waiting for you to go back?"

The old man was busy picking off the wrong formula on the ground with his hands, and using the branches to make up for it again, and he didn't even have the strength to look back at Li Yuan.

He worked hard for a long time before he said without looking back: "For science."

“For…science?”

Li Yuan looked confused.

"What a stupid little guy. No wonder I can fall off even if I cross a bridge." The old man's tone was full of deep disdain and contempt. "When I was on land, I had to socialize endless banquets and interpersonal interactions, deal with the upper class of the Giant Tree God Cult who only knew power and believers who were seeking immortality, and were worried about whether the monthly salary was enough to maintain the life of a big family... And here, I was the only one, and I could calculate and study day and night, without eating or sleeping. No one would disturb me, and no one would chatter like a naughty child during my working hours."

Of course, the old man's last sentence obviously mocked Li Yuan.

Lu Lie smiled: It was interesting. Unexpectedly, after Li Yuan fell into the suspension bridge, he accidentally hit him and was rescued by an "old scientist" living at the bottom of the valley.

Li Yuan thought about it. Obviously, after being ridiculed by the old man, he did not have even a little repentance. Soon, he became shamelessly whispered: "Your words made sense in the first day of the first day, but I can't coax my unparalleled master Li Yuan! You said you can study your academics here quietly. But have you ever thought that even if you solve the world's number one problem here, so what? No one knows what you do here. You will stay here alone with your achievements forever, and always do your useless work."

The old scientist stopped what he had done, turned around, and looked at Li Yuan coldly with a cold look that could kill people.

Li Yuan thought that his words angered the other party. He shrank back in fear and forced himself to say, "Why... can't you tell me, are you going to hit someone? Don't forget, you are a scientist! Scientists must have demeanor."

But the old scientist just glanced at him coldly, then turned around and drew his own formula.

"Who said my research here is useless?"

The old scientist marked a new circle he drew, "Everything I did here is to stop Yao and his ambitions that remained five hundred years ago."

Yao!

I can’t count the number of times I heard this person’s name. Lu Lie’s pupils still shrank into two points.

This old guy has obviously disappeared for more than five hundred years. However, what he did and what he left on the giant tree still far-reachingly influenced Lu Lie's generation. No one can even confirm whether he is dead or whether he is still hiding in a place in the giant tree world, and coveting all tree climbers in a slight way.

Here, the old man heard the word "Yao" again in his mouth. How could Lu Lie not be excited? He was already waiting to hear some new clues about Yao from the old man's mouth.

"Yao?" Back in the vision, Li Yuan tilted his head and seemed very curious, "I have heard of this man's name. He is a great secret master, and he seems to be... the top leaders of the Giant Tree God Cult, right? He also organized a second expedition, and finally, along with his last hundred believers, left a huge city inside the Giant Tree. He completely disappeared."

The old man smiled and said, "Little brat. Although I don't know where you got so much information. But you know so much, it means that you didn't do much homework before climbing the tree.

“But one thing, you are still wrong.

"Yao did not disappear at all. On the contrary, he was still alive, and lived well, better than each of us."

Li Yuan was dissatisfied: "Grandpa, bragging is not a good habit. You have been staying in this cave for so long and haven't been out. It's understandable that you are bored and make up some stories by yourself. However, what you told me was that Yao disappeared was a member of the expeditionary army back then. What he said was much more reliable than what you thought about here by yourself."

After all, one is three people who experienced it back then, and the other is an old man who built a car behind closed doors in this cave. Li Yuan did not hesitate to believe who he should believe.

"Oh? It turns out that some people survived the expeditionary army back then?" The old man smiled, "I thought I was the only one hiding here back then and escaped the disaster."
