Chapter 3693

Ye Liuyun had already gone deep into the cave at this time, completely unaware of what happened outside.

He also thought that the royal family would not let it go, but that was after he came out. As long as he stays in this cave, he is safe now, other martial artists don't have the courage to enter the cave like him.

Ye Liuyun's golden pupils also saw far away. Although there is also a devilish aura here, he can still see it far away. He didn't see any devils in this cave.

It's just that this cave is at least tens of thousands of miles deep, and it looks more like an underground passage. Whether there is any hidden danger in it, he does not know for the time being.

Now he can only probe downward cautiously. However, wherever his divine sense and Jin Tong could see, he didn't find any danger. There was no sign of a sudden eruption of evil spirit in the cave.

Half a day later, Ye Liuyun had already sneaked into the passage nearly ten thousand miles away, and vaguely saw a light at the end of the passage. And occasionally the figures of Warcraft and Demon Men flashed by.

So he also accelerated to approach those monsters again, put on the invisibility cloak, restrained his aura, and wrapped his whole body with demonic aura.

And just when he was about to reach the end of the passage, he discovered that there was a formation in front of him that sealed the passage.

This formation can't block Jintong's line of sight, he has already seen the scene in it. The inside is like an underground space, and there are some giant pillars like mountains supporting this underground space.

The evil spirit in this underground space is very strong. Some demons are directing the monsters to help dig spars everywhere, and there are many demon villages inhabited by simple stone houses.

Most of the demons and monsters who are working are in the realm of the cave, and only in the villages and areas where the monsters live, there are some monsters with lower realms.

"It turns out that the lairs of these monsters are underground." Ye Liuyun also suddenly realized.

But then he became curious again: "Since these monsters don't have the ability to refine weapons, how did this formation come about?"

But at present, he can't find the answer, so he can only break in and get in first.

He didn't dare to charge directly or use white light to break the formation, for fear of attracting the attention of the devil. You can only use the golden pupil to carefully observe the formation, and then use the clone puppet to describe it in the space world, and hand it over to Qiongqi and other formation masters to study the method of breaking the formation.

However, the formation that he copied perfectly has no defensive effect in his spatial world. Qiongqi and other formation mages were also very puzzled.

"This formation seems to be able to block it, but why can't it be activated here?"

Ye Liuyun completely left the formation to them to study. If these people can't crack it, then he certainly can't help.

He stayed outside the formation, monitoring every move of those demons, and saw some monsters dug out spars of various colors from the ground and handed them to the demons. The devil brought these crystals back to the tribe and handed them over to the patriarch for distribution.

He also saw a monster altar made of metal with two square pools on it. One of them is thick black gas, and the other is blood red gas.

Ye Liuyun guessed that in these two pools, one is pure demon energy and the other is evil energy. He also saw some demons entering it to practice. It's just that he can't see any rules, and he doesn't understand why these demons practice separately.

A few days later, Qiongqi and other formation mages did not find a way to break the formation. Five demons had already gathered under this formation, and it seemed that they were going to go out on patrol. ..

"It's time for them to patrol!"

Ye Liuyun also paid attention immediately, wanting to see how these demons left the formation. If the formation can be opened at this time, he will take the opportunity to sneak in.

But what he didn't expect was that these five demons directly penetrated the formation and rushed upwards.

"This... the devil is not affected!" Ye Liuyun was also speechless.

"Wait a little longer and see if they will activate the formation when they go back!" Ye Liuyun was also comforting herself.

In less than two hours, those demons returned quickly. Moreover, the speed did not decrease, and they directly passed through the formation and returned to their underground world.

Ye Liuyun immediately followed suit. He approached the formation without using any force, but he clearly felt that the formation had repelled him.

He didn't dare to try again, so he could only tell Qiongqi about the situation, hoping to help them break the formation.

Five days later, Ye Liuyun waited for the demons to patrol again, but they were still the same as last time, moving through the formation at will.

At this time, Ye Liuyun also discovered that the evil spirit in the underground space began to become more and more intense. Especially near the formation, the evil energy gathered more and more, and it had already begun to affect his sight. He looked at it now with golden pupils, and it was filled with black air.

He also guessed that the more evil energy gathered here, the more it would be erupted through this formation in a few days for the monsters outside to cultivate.

But until now, Qiongqi and the others still have no clue about the formation. Even letting Ye Liuyun bleed a devil's blood and try to wrap his finger with the devil's blood, he would still be repelled by the formation.

On Ye Liuyun's side, he was also prepared mentally. On the one hand, he prepared to protect his body with Buddha's light, and on the other hand, he prepared to forcibly use white light to break through the formation. He even planned his escape route after entering.

But at this moment, Ye Liuyun made a big discovery in his spatial world. It turned out that when Qiongqi and others were bleeding the demons, those demons were right next to the formation. At that time, no one paid attention to their expressions.

But suddenly, a demon actually learned that formation. These demons dug a hole in the ground, buried themselves in it, sealed the hole with the formation, and then began to dig holes into the ground.

This made Qiongqi and other formation mages very excited, and they tried to break the formation in various ways. But after tossing for two days, they were also depressed.

Because the formation is not difficult to crack, but no matter what method they use to break the formation, the demon will immediately repair the damaged formation.

After Ye Liuyun got this result, he also asked Qiongqi and the others: "That is to say, this formation is probably cast by a strong demon, and only the blood of the demon can pass through it at will.

And no matter what method I use to break the formation, will I be noticed by the demon who cast the formation? "

"That's right, the conclusion we have reached so far is this!" Qiongqi also confirmed.

"Then let Lei Ming try to use white light to break the formation, I'll see the effect!"

Ye Liuyun saw that since it was unavoidable, he had to force it, and breaking the formation with white light was the fastest way. Even if he was discovered by the demon after breaking the formation, he would still have some time to escape.

Lei Ming also immediately emitted white light to break the formation. As a result, the defensive ability of the formation was not very strong, and a big hole was instantly melted by the white light, allowing one person to pass through easily.
