Ye Liuyun had already gone deep into the cave at this time and was completely unaware of what was happening outside.
He also thought that the royal family would not give up, but that was what happened after he came out. Now he would be safe as long as he stayed in the cave. Other martial arts cultivators did not have the courage to enter the cave like him.
Ye Liuyun's golden eyes could also see very far. Although there was a demonic aura here, he could still see very far. He did not see any demons 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. He doesn't know if there are any hidden dangers in it.
Now he could only cautiously explore downwards. However, wherever his spiritual sense and golden eyes could see, he did not find any danger. There was no sign of a sudden outbreak of evil spirit in the cave.
Half a day later, Ye Liuyun had sneaked into the passage nearly ten thousand miles away, and vaguely saw a bright light at the end of the passage. Occasionally, figures of monsters and demons flashed past.
So he speeded up and approached those monsters again, put on an invisibility cloak, restrained his aura, and wrapped himself in demonic energy.
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 couldn't block Jin Tong's sight. He had already seen the scene inside. It was like an underground space, with some huge mountain-like pillars supporting the underground space.
The evil spirit in this underground space is very strong. Some demons are commanding the demon beasts to help dig crystal stones everywhere. There are also many demon villages where people live together, all of which are simple stone houses.
Among them, most of the working demons and monsters are in the cave-heaven realm. Only in villages and areas where monsters live, there are some lower-level monsters.
"It turns out that the lair of these monsters is underground." Ye Liuyun also suddenly realized.
But then he became curious: "Since these monsters don't have the ability to refine weapons, how did this formation come about?"
However, he can't find the answer at the moment, so he can only break the formation and sneak in first.
He didn't dare to rush directly or use white light to break the formation, for fear of attracting the attention of the devil. He could only carefully observe the formation with golden eyes, and then use the clone puppet to depict it in the space world and hand it over to Qiongqi and other formations.
The mage went to study how to break the formation.
However, the formation that he copied perfectly has no defensive effect in his space world. Qiongqi and other formation masters are also very puzzled.
"This formation does seem to be able to block it, but why can't it be activated here?"
Ye Liuyun left the formation completely to them to study. If these people couldn't crack it, then he definitely couldn't help.
He stayed outside the formation, monitoring every move of the demons, and saw with his own eyes some demon beasts digging out crystals of various colors from the ground and giving them to the demons. The demons then brought these crystals back to the tribe,
Leave it to the clan leader for distribution.
He also saw a monster altar made of metal, with two square pools on it. One of them was filled with rich black gas, and the other was filled with blood-red gas.
Ye Liuyun guessed that one of the two pools contained pure demonic energy and the other contained evil energy. He also saw some demonic beings entering them to practice. However, he could not see any patterns and did not understand why these demonic beings separated.
Practice.
A few days later, Qiongqi and other formation mages also did not develop a method to break the formation. Five demons had gathered under the formation, and it seemed that they were obviously preparing to go out on patrol.
"It's time for them to patrol!"
Ye Liuyun also immediately paid attention, wanting to see how these demons left the formation. If the formation could be opened at this time, he would take the opportunity to sneak in.
But what he didn't expect was that these five demons directly penetrated the formation and rushed upward.
"This... the devil is not affected!" Ye Liuyun was also speechless.
"Wait a little longer and see if they will open the formation when they go back!" Ye Liuyun was also comforting himself.
Less than two hours later, those demons returned quickly. And their speed did not slow down. They passed through the formation and returned to their underground world.
Ye Liuyun immediately followed suit and tried it. He approached the formation without using any force, but he clearly felt that the formation had a repulsive force on him.
He didn't dare to try again, so he could only tell Qiongqi about the situation, hoping it would 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, randomly moving through the formation.
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 spirit gathered more and more, and it began to affect his sight. He now used gold
As he looked down, he saw a black air.
He also guessed that the more demonic energy gathered here, the more it would be erupted through this formation in a few days for the demons outside to practice.
But until now, Qiongqi and others still have no clue about that formation. Even if they tried to bleed a demon and let Ye Liuyun wrap the demon's blood on his fingers, they would still be rejected by the formation.
Ye Liuyun was also mentally prepared. On the one hand, he was preparing to use Buddha's light to protect his body, and on the other hand, he was preparing to use white light to forcefully break the formation. He even planned his escape route after entering.
But at this moment, Ye Liuyun made a big discovery in his space world. It turned out that when Qiongqi and others were bleeding the demons, the demons were beside the formation. No one paid attention to their expressions at that time.
But suddenly, a demon actually learned that formation. These demons dug a hole in the ground, buried themselves in it, and then used that formation to seal the entrance of the pit, and then began to dig holes underground.
This made Qiongqi and other formation masters very excited, and they tried various methods to break the formation. But after two days of struggling, they also became depressed.
Because the formation is not difficult to break, 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: "In other words, this formation was probably performed 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, I will be noticed by the demon who uses the formation?"
"Yes, this is the conclusion we have reached so far!" Qiongqi also confirmed.
"Then let Lei Ming try to use white light to break the formation, and let me see the effect!"
Ye Liuyun saw that since it was unavoidable, he had no choice but to do it forcefully, and using white light to break the formation was the fastest way. Even if he was discovered by the demon after breaking the formation, he would have some time to escape.
Lei Ming also immediately fired white light to break the formation. As a result, the defensive ability of the formation was not very strong, and the white light melted into a large hole in an instant, which could easily allow one person to pass through.
