Xu Yuntian and Yan Xiaoyu were nothing when they saw the skeleton bones. Cui Yingying and others were so scared that they trembled all over when they saw the skeleton bones. They all hid nervously behind Xu Yuntian.

The four security guards were lying next to the skeleton bones, as if they were asleep. Xu Yuntian said to Yan Xiaoyu: "Xiaoyu, go and save them!"

Yan Xiaoyu turned his head and looked at Chanji and said, "Greedy Chicken, how should I save them?"

"Just like the master's technique, crush their greed and obsession, and they will wake up!" Chan Ji said to Yan Xiaoyu.

Yan Xiaoyu nodded. He walked beside the four security guards and found that three of them had great greed and obsession, all of which were shadows of gold, silver and jewelry.

Only one security guard's greed and obsession was different from the other three. He was the security guard who called the principal. His greed and obsession was not gold, silver and jewelry, but wanted to become the security manager of Blue and White University.

Yan Xiaoyu crushed their greed and obsession. After a moment, the four security departments woke up. The security guard who called Principal Fang woke up and exclaimed: "Oh! Where am I? I saw a monster biting me just now!"

When he was calling Principal Fang, a monster appeared in the illusion. The monster rushed towards him and he was shocked.

"Don't be afraid, those were hallucinations just now. You have entered the illusion." Yan Xiaoyu said to the four security guards.

"Uh! We're in the illusion!" A security guard said disappointedly. He was still thinking about the gold, silver and jewelry just now.

Xu Yuntian shook his head secretly and said, "No wonder those who entered the Illusion Castle are dead, because their greed and obsession have been in control of them, and they starved to death."

Xu Yuntian and everyone left the Illusion Castle, and then Zen Ji put away the Illusion Castle scroll. There was a rock in front of everyone. They saw the flying waterfall in front of them.

"Oh! Feishui Waterfall! We are finally back!" Cui Yingying said happily, but she still felt a little confused because she liked what happened in the illusion.

Xu Yuntian and others returned to Blue and White University. President Fang and Cui Yingying's mother were waiting at the gate of Blue and White University. Seeing that everyone was safely back, Principal Fang finally breathed a sigh of relief.

Cui Yingying's mother saw Cui Yingying and hurriedly ran over, shouting while running: "Yingying! Are you okay?"

Cui Yingying looked at her mother and smiled and said, "Mother, I'm fine!"

Principal Fang walked to Xu Yuntian and said with a smile: "Xu Yuntian, thanks to you this time! You are the first person to come out of Feishuijian!"

"Haha! It's nothing!" Xu Yuntian said with a smile.

"By the way! What's the secret of Feishuijian?" Principal Fang said curiously.

Xu Yuntian shook his head and smiled, "I don't know what the secret is in Feishuijian!" Of course, he could not tell Principal Fang about Feishuijian Fantasy Castle, that's a secret.

Principal Fang was very slick. He guessed that there must be some secret here. Xu Yuntian didn't want to tell it, and he couldn't ask about it anymore.

"Oh! There is one more thing to tell you!" Principal Fang pointed at Xu Yuntiandao.

"Oh! What else is there?" Xu Yuntian looked at Principal Fang and said with a smile.

"Hey! Just when you were going to Feishuijian, something strange happened to the school." Principal Fang frowned.

"Oh! What strange things happened in the school?" Xu Yuntian said in surprise.

"In the third class this morning, when the Trade Department was taking foreign language class, the students in the back row suddenly disappeared." Principal Fang frowned.

Xu Yuntian showed surprise, "What! During class, the students in the back row suddenly disappeared. Could it be that they ran out?" Xu Yuntian looked at Principal Fang and said.

"At first, I thought it was a naughty student in the back seat. I sneaked out of the classroom during class."

"But I asked the teacher in class that the teacher was facing those students. She didn't see the students leaving, and the six students disappeared together, so it was impossible to see them." Principal Fang said.

"Oh! The six students disappeared together. What was going on at that time?" Xu Yuntian looked at Principal Fang and said.

"I heard from foreign language teacher Mr. Zhou that I didn't feel anything at that time. I just felt the air fluctuation for a while. She suddenly found that the six students had disappeared." Principal Fang said.

Xu Yuntian thought for a while and said, "Principal Fang, do this, take me to the class and take a look!"

Principal Fang nodded and said, "Okay, I'll take you to the trade class!"

About five minutes later, Xu Yuntian followed Principal Fang to the trade class. There were 48 people in the trade class, and there were still 42 people left in the class. They all looked frightened.

Xu Yuntian and Principal Fang appeared in the classroom. Principal Fang pointed to the empty seat at the end of the classroom and said, "It's the six students there that disappeared!"

Xu Yuntian walked to the back of the classroom. Xu Yuntian observed carefully and found nothing abnormal.

"The six students suddenly disappeared. There are only three possibilities. One is that they will all teleport in space, and they will teleport out together! The other is that they were kidnapped by someone using their space powers."

"Three, there was a sudden change in space and cracks appeared, and six students were sucked into the cracks in space." Xu Yuntian said to himself.

First of all, we can exclude the first type. The six students cannot have the ability to have space teleportation. They are neither psychopaths at all.

Then there are only two possibilities. Thinking of this, Xu Yuntian looked at Principal Fang and said, "Principal Fang, where is Teacher Zhou?"

"Go and call Teacher Zhou!" Principal Fang said to Director Cai outside the door.

Director Cai nodded and said, "Okay, I'll call Teacher Zhou right away!"

A moment later, a woman in her thirties appeared at the door of the classroom and said to Principal Fang: "Principal Fang, are you having something to do with me?"

"Teacher Zhou, Teacher Xu has something to ask you!" Principal Fang said to Teacher Zhou.

Teacher Zhou turned his head and looked at Xu Yuntian and said, "Teacher Xu, what do you have to ask me?"

"Teacher Zhou, was there anything unusual in the classroom before the six students disappeared?" Xu Yuntian looked at Teacher Zhou and said.

Teacher Zhou frowned and thought for a while and said, "I didn't feel anything abnormal in the classroom before the six students disappeared!"

"Teacher Zhou, think about it carefully, such as space fluctuations, or trembling on the ground, or any abnormal sound." Xu Yuntian reminded.

"Oh! By the way! I felt the podium tremble for a while." Teacher Zhou said hurriedly.

"The podium shook for a moment!" Xu Yuntian nodded.

"By the way! After the six students disappeared, is there anything unusual in the classroom?" Xu Yuntian looked at Teacher Zhou and said.

"The air fluctuated a little, and I found that the six students suddenly disappeared." Teacher Zhou looked at Xu Yuntiandao.

Xu Yuntian nodded and said, "Teacher Zhou, no one passed by the classroom door at that time?"

Teacher Zhou frowned and said, "I didn't have any idea outside the classroom at that time."

"Teacher Xu, a man passed by outside the classroom at that time!" a student shouted.
