"What's wrong?" Seeing Ye Xiu's expression even though he looked, Long Zimu, who had been following Ye Xiu, said curiously.

"One person is missing!" Ye Xiu's eyes swept across everyone, and he counted silently, and one person was missing.

"What?" Everyone was suddenly shocked, and felt a chill all over their bodies. They looked at each other one by one, and then they heard Li Shiyan's voice sound: "It's Brother Zhang Qiang, Brother Zhang Qiang is gone!"

Everyone felt the hairs on their bodies standing up. Zhang Qiang, this is Professor Li's assistant and Professor Li's student. The three professors were supported by Feng Zhennan, Chu Tianhe, and Ye Yuting, and kept walking in the middle. Zhang Qiang, Li Shiyan, Wang Zhong and others walked together, but now they are gone.

How can this not be terrifying?

Ye Xiu glanced at Long Zimu, and Long Zimu shook his head very simply.

"Instructor, I didn't find anyone behind!"

After turning around, he and Ye Xiu walked at the end, one on the left and one on the right. If someone really fell behind, they would not have noticed it.

But now, a living person has disappeared out of thin air.

How can this not be shocking?

Ye Xiu didn't speak, he was just trying to recall all the details of the journey.

When he returned, he had also counted the number of people silently. He was still sixteen years old at that time. Zhang Qiang disappeared, and he must have been on the way back. However, how did he disappear?

The others also held their breath, even Professor Li remained silent at this moment.

It's really weird here.

"When did you last meet Zhang Qiang?" Ye Xiu looked at Li Shiyan and others.

They all walked in the center and kept walking with Zhang Qiang.

Everyone frowned and tried hard to recall the moment when they finally saw Zhang Qiang, but the passage was too strange. They were always shrouded in fear and just wanted to go out as soon as possible. For a moment, no one could recall when he finally saw Zhang Qiang.

Seeing everyone's expressions, Ye Xiu understood that he could not find any clues to rely on them.

According to the current situation, the most appropriate plan is to send these people out first, and then look back to find Zhang Qiang's whereabouts, but they have been away for so long and have not found the door when they came. If they continue walking, they are afraid they will not be able to go out at all.

And Zhang Qiang, a living person, would never be able to disappear for no reason.

"Zhang Qiang left there just now!" Ye Xiu pondered for a moment and asked again.

Since you can't go out immediately, let's investigate the reason for Zhang Qiang's disappearance first, and maybe you can find a way out.

"Here!" Li Shiyan pointed to the right side of the passage and said.

They had been walking here just now, and Zhang Qiang saw that she was a girl, so he asked her to walk closer to the middle, while he was walking outside, but he disappeared because of this.

Ye Xiu did not speak, and strode to the wall on the right, carefully observing the wall with a searchlight.

The walls are very smooth and have no traces.

Then he turned around and shot at the opposite wall. It was clearly a few meters away, but it was still pitch black when it was touched.

"Zimu, lean on the opposite side!" Ye Xiu said to Long Zimu.

"Yes!" Long Zimu nodded, quickly retreated back and retreated to the wall. Even though Ye Xiu and he were holding flashlights, they could not see each other at all. In this case, someone suddenly disappeared, and it was really difficult to be discovered.

"Professor, do you think we are going around the circle all the time?" Ye Xiu looked at Professor Hu.

"How is it possible? This corridor is obviously straight!" As a result, Wang Zhong jumped out again.

"It's very likely!" As a result, Professor Hu ignored his students' words at all and nodded slightly.

They have been walking for so long, let alone an ancient tomb, even an underground palace has already walked through it. The only possibility is that they have been in circles.

Wang Zhong opened his mouth but did not dare to say anything more. He could question Ye Xiu, but he absolutely did not dare to question his teacher.

After receiving the affirmation of Professor Hu, Ye Xiu took out a military dagger and carved a trace on the wall. If this was really a circle, as long as he walked around, he would always return to the starting point.

But what Ye Xiu didn't expect was that the traces were easily carved, but the traces were actually repaired at a speed visible to the naked eye. In just a moment, they disappeared without a trace, as if they had never existed.

Professor Hu also noticed this and frowned slightly!

The material of this wall is too weird and it actually has the function of automatic repair. How effective will this material be if it is taken outside?

"Zi Mu, take a backup searchlight and turn it on and put it in the corner of the wall!" Ye Xiu placed the searchlight flashlight in his hand in the corner of the wall while facing Longzi Mu on the opposite side.

Long Zimu nodded, took out a brand new searchlight from his backpack and placed it in the corner.

In this way, if they are really in circles, they will always go back. As long as they see these two flashlights, they can prove whether they are going around in circles!

"Now should I continue moving forward? Or backward?" Professor Hu nodded, and was very impressed by Ye Xiu's care.

It is rare for such young people to be so young and do things so calmly.

"From the way, before returning, Zhang Qiang is still there. No matter what reason he is missing, he will always be on this road. Maybe some clues can be found!" Ye Xiu said.

The others also nodded one after another, about to set off, but Ye Xiu spoke again.

"But we have to change our way of walking this time!"

"Hmm?" Everyone was stunned.

"Although the light in this passage is difficult to shoot far, the corridor is wide. There are so many of us who can be combined into a row. Please carefully check the wall along the way, and maybe you can find something!" Ye Xiu looked at the dark wall and said.

"It makes sense!" Professor Hu gave Ye Xiu a thumbs up. Whether he was going around in circles or entering a maze, as long as everyone was standing side by side, they could always find some clues.

Ye Xiu made arrangements, and he and Long Zimu walked on the far side, and the other five members of the Tiger Teeth Team were inserted into the center of Professor Hu and his group. If there was any movement, they could provide support as soon as possible.

In this way, everyone was almost alone, and they were not worried about anyone falling behind again.

The only trouble is that once there is danger ahead or behind, Professor Hu and others may also face the danger directly!

Arranged the formation, everyone turned around and continued to walk in the direction just now.

After walking for about ten minutes this time, Ye Xiu stopped.

"What's wrong?" Li Shiyan, who was approaching Ye Xiu, asked.

To be honest, she was always a little excited when she was able to walk with Ye Xiu, and even made her forget a lot of fear. It was just because she was worried about Zhang Qiang that this excitement became much weaker. Seeing Ye Xiu suddenly stop, she said curiously.

"Look!" The searchlight flashlight in Ye Xiu's hand shone a meter away in front.
