Ye Linfeng and Lai Wu walked a long distance to reach the seventh layer of the tomb, the seventh layer was indeed below the sixth layer, but there was a long distance to reach the main tomb.

"Fourth Senior Brother, where have we been?" Ye Linfeng felt that he had walked a long distance, and the location he was in now was no longer under the altar.

"Grandma's, where do I know, after robbing the tomb for more than ten years, it is the first time I have seen such an evil tomb, I guess we are outside the city. Lai Wu said scoldingly.

Ye Linfeng walked into the seventh-floor tomb and saw a cave with a huge space, and when the two saw this scene, they thought that they were indeed outside the city, maybe in the cave of which mountain.

The two guessed correctly, at this time they had indeed arrived outside the demon city, and they were in the cave of Benlei Mountain, the most famous demon clan.

Go to the depths of the cave again, see a small round lake, there is a pumice stone in the center of the lake, the pumice stone is cyan, crystal clear, simple and without losing the aura, like a kind of jade, there is a thing on the pumice stone.

The thing that was placed on the pumice stone in the center of the lake was the Heavenly Demon Bow that Ye Linfeng had dreamed of, and that pumice stone was the ancient spirit jade that Lai Wuyi was looking for.

"Heavenly Demon Bow!" Ye Linfeng and Lai Wu exclaimed at the same time, but they didn't dare to take a step forward, because no matter how you look at this circular hole, the small lake is very wrong, the water in the lake flashes with a metallic luster from time to time, there are no swimming fish in the lake, not even a single aquatic plant can be seen.

"That pumice stone seems to be the ancient spirit jade I am looking for, but I didn't expect that the legendary box of ancient spirit jade turned out to be a piece of jade floating in the center of the lake, today is really an eye-opener. Lai Wu was very excited to see the ancient spirit jade that he was bent on finding.

"Senior brother, there is something wrong with this lake, could it be that there is any formation?" Ye Linfeng asked.

"I think so, why don't we try it. Without saying a word, he picked up a piece of gravel from the hole and threw it into the lake.

Just heard the sound of "pop", and the piece of rubble turned into flying ash in an instant, and disappeared instantly.

Ye Linfeng and Lai Wu glanced at each other, quickly understood something, and looked at the treasure they dreamed of on the opposite side and were a little at a loss.

"Thunder Pool Array, it's over, I think we have no chance with these two treasures. Lai Wu said with a sad face, his face as ugly as eating a dead child.

"One of the most ferocious formations in ancient times, once you step in, it immediately turns into ashes. Ye Linfeng said in a low voice, a little disappointed.

But he quickly adjusted his state, and he was thinking that since it was a formation, there must be a way to crack it for so long.

He has read through all the scriptures and Taoist collections in the Mixed Yuan Immortal Sect Washing Pavilion since he was a child, although the realm has not broken through, but there must be no harm in reading too many good books, unless he can't use them, plus the basic unique book collection that he secretly read in the Tianzhao Pavilion of the Tianzhao Academy, he has a lot of understanding of the formation.

"Senior brother, what do you think, I think let's go home, I really will have weak legs when I see this thunder pool." Lai Wuzhan looked at the water in the lake tremblingly, thinking that once he stepped on it, it would be as dusty as the previous stone, how could he not panic.

Ye Linfeng picked up a small pebble and sketched it on the ground by the lake, and he sketched it while looking at the thunder pool.

There is a small circle drawn on the ground, and the small circle is the small lake called Lei Chi, and there is a mark in the center of the small circle, and this mark is the ancient spirit jade pumice stone in the center of the lake.

Looking at the surroundings of the lake, there are several rocks of different sizes scattered around, and those who are familiar with the formation will find that these scattered rocks are actually several formation eyes of this formation, and the ancient spirit jade in the center of the lake is the largest formation eye of the Lei Chi Formation, and the layman really can't see it, even Lai Wu, an insider who digs people's ancestral graves all day long, does not see the clues.

In fact, this is very normal, there are no ancient records of several murderous formations in ancient times, and many people have never talked about one in their lives, unless they have seen it when they are dying.

"Senior brother, I've found a way. Ye Linfeng squinted slightly at a pair of envious Danfeng eyes, looked at the small lake, and said with a smile.

"Grandma's bullshit! Playing this kind of joke with me, I, an insider, don't even see when I still joke with me. Lai Wu said scoldingly.

"Senior brother, I'm really not joking with you, to be honest, I'm definitely not as good as you in digging people's ancestral graves, but I do know a lot about formations, because I have read a lot of books. Ye Linfeng responded.

Indeed, Ye Linfeng has really read a lot of books, and he doesn't just swallow jujubes when he reads, on the contrary, he chews repeatedly like an old cow chewing hay, really understands the deep meaning, and will further extend them, it is not an exaggeration to say that he is a scholar.

"Okay, then what do you say you can do?" Lai Wu didn't believe it at all, and looked at the junior brother in front of him like a fool.

"Well, with Senior Brother Lao, you have to exert a little more strength. Ye Linfeng said with a smile, I don't know what kind of medicine is sold in the gourd.

"As long as we can get what we want, I'll be happy to strip naked and dance on the street. Lai Wu said, that Lai's face is rare in the world.

"Senior brother, you go and knock on those stones, I want to observe the reaction of the ancient spirit jade in the center of the lake, you keep knocking, you stop when I shout stop, I say change the stone and knock you will change. Ye Linfeng said while thinking.

"I'm going to let go today, I'll be a monkey trick for you, who made you my little junior brother. Lai Wu said.

Lai Wu followed Ye Linfeng's instructions, walked to a big rock, and picked up a small stone.

"Let's go!"

Lai Wu knocked on the rock in front of him.

"Stop!"

Lai did not stop.

"Knock again. ”

"Okay, stop. ”

"Knock. ”

"Wait a minute, brother, change the rocks and go over there. ”

"Okay, knock. ”

"Stop. ”

"Change places again. ”

"Knock. ”

"Stop. ”

In this way, Lai Wuzhen became a monkey, and under Ye Linfeng's instructions, he knocked for a while, stopped for a while, and changed places for a while.

Ye Linfeng didn't have time to look at his fourth senior brother's wolf appearance at this time, he was carefully observing the changes in the brightness of the jade in the center of the lake, and wanted to come up with a rule, maybe this law is the solution, even if there is only a little breakthrough, otherwise this thunder pool will not be able to go over.

(Wait until the fireworks cool down)
