The soldiers behind Li Yun also came, a group of people beating here looking for suspicious traces, but they found nothing.

Xiao Jiayu gave up searching, straightened up and looked at the corridor ahead, sighing: "There is a dead end ahead. Gu Jiyu should have disappeared here. How could he disappear? Li Yun, where did you say he is now? "

Where she couldn't think of, she threw it to her boyfriend.

Everyone looked at each other, and they also had the same problems as Xiao Jiayu.

Li Yun asked Xiao Ai: "Are there any electromagnetic waves detected nearby?"

"No." Xiao Ai shook his head distressedly, "Nothing like that was returned from the machine, maybe Gu Jiyu used other methods to verify it."

In other words, Gu Jiyu did not use electromagnetic induction to open the secret room.

Li Yun put his chin in his hand and began to meditate, "Jiayu, when we chased, Gu Jiyu disappeared in front of us through the corner, right?"

"Um~~~" Xiao Jiayu followed Li Yun's movements, touching her clean chin with a small hand, and said: "It's about three seconds, not bad."

The people around were envious of the little gestures of the two of them, but there was no way. Both of them were important figures. Who is Xiao Jiayu, who is also a powerful innate master? It is reasonable for her to appear here.

Li Yun said: "Weird places have come. Generally speaking, even the fastest verification method, that is, the door that can be opened by swiping an electromagnetic card, takes at least 3 seconds from opening to closing, let alone It is true that the ancient monsoon rain should pass through a gate that is at least half a meter thick. In theory, the time in between is not enough."

"That's right." Xiao Jiayu immediately agreed with him. "That thick door requires a lot of strength. If you open it quickly, it will make a loud noise, but we didn't hear anything."

"Unless, he fell into the ground."

Li Yun looked at the ground, and everyone immediately checked again, but the sound coming back through the tap was still dull and there was no empty place.

Without even letting go of the ceiling, the soldiers checked the upper part by holding one by one.

"Weird, so weird~! Li Yun, how did you tell him to run?"

After Xiao Jiayu had passed the initial suspense, she became excited now, feeling extremely curious about this weird situation. Seeing her smiling face, Li Yun almost caught up with the curious baby Ishanshan.

"Even with the chameleon potion, if we leave quickly, we will hear footsteps, followed by the soldiers following us."

Xiao Jiayu raised a question. Li Yun glanced at the dusty and stained ground, and said: "Chameleon potion is not very effective here. The ground is too dirty, and it is not easy to see if it is not as clean as the Qingya Institute."

"It hasn't become transparent, and there are no secret passages. There are no walls up, down, left, and right." Xiao Jiayu was surprised: "Gu Jiyu disappeared like this? Is it because the whole person is broken down into cells and slipped away from the wall? Or is it a ghost? of……"

She didn't even believe this, and she laughed at the end.

"I still believe in science." Li Yun glanced at her and said, "Maybe we have all entered a misunderstanding of thinking."

"What's wrong?"

"We should go back to the beginning and think about how the ancient monsoon rain disappeared in the corridor within 3 seconds, without using black technology."

Li Yun looked at the wall, and he vaguely had a guess.
