Chapter 1864: Disappeared

Bai Yuzhe watched quietly from above, and the mountain suddenly collapsed, which also surprised him. At the beginning, he could also guess that if the two areas of forbidden air and gravity were lifted, there should be some anomalies, but he could not guess that even the entire mountain would disintegrate.
This vision is a bit exaggerated. The most important thing is that this mountain originally gave all of them the feeling that it will never collapse because the mountain is too difficult to destroy.
After two minutes passed, the mountain was still in collapse, more than a thousand meters at any rate, and it collapsed completely not too soon. At this time, a figure flew quickly from a distance in the air, stopped when it got closer, then landed, and joined Yan Fei and the others.
Bai Yuzhe's eyes condensed, and this person was Yan Junhe, the nine-layered heavenly powerhouse of the Holy Vault he had seen in the Palace of Silver Wolf Kingdom. Bai Yuzhe guessed that the first group of people who came to the Black Demon Palace were probably these two Holy Vault Nine Heavens, right?
Of course, this is just a guess, and there are a few specifics, which are still unclear.
"What happened?" Yan Junhe suddenly saw the scene when he arrived here, and couldn't help but ask.
"Elder, the group of people have been trapped on the mountain, but I don't know why. The mountain suddenly disintegrated and collapsed a few minutes ago, and we still don't know what happened." Yan Fei explained.
"Stuck on the mountain? When I flew over, I didn't see anyone on the mountain." Yan Junhe frowned and said.
"What? How is it possible? We have been guarding, even if it is on the other side of the mountain, there are always people watching, how could it suddenly disappear?" Yan Fei's eyes widened and said incredulously.
"No, has the opponent lifted the restricted air domain and flew away?" Venerable Lin was suddenly startled at this time, thinking of this possibility.
He had always guessed that Bai Yuzhe could not unlock the forbidden air field in such a short time, but that was just a guess after all. He didn't even know how high Bai Yuzhe's formation skills were.
"However, if they fly away, from any direction, we should be able to see it!" Someone asked puzzledly at this time.
"They are very likely to have a way to become invisible. But if so many people and beasts can become invisible, it would be incredible." Yan Junhe said.
For Bai Yuzhe and others to be invisible, in fact, they have not been very sure. Because at the beginning, the people in the Black Demon Temple chased and killed some of the Eighteen Blood Guards, and they discovered something vaguely.
But after all, I didn't see those people disappearing directly in front of me, nor did I see those people suddenly appearing in front of me.
Only a few times, when the Eighteen Blood Guards were hiding and escaping, they accidentally sent out formation fluctuations and were felt, so they found a place and showed themselves, making the other party unsure.
It was the same with Yan Junhe. The first time he felt it was when Bai Yuzhe used his mental power to scan the place where he was when he was visiting the palace at night.
At that time, Yan Junhe had heard that the other person could be invisible, so he tried, but still to no avail. So now, neither of them can be sure whether the other party can be invisible. If so, how is it done?
