Jiang Cheng thought for a moment and said, "Xiao Ting came back to you last night because you are her best friend, and she hopes you can help her."

"I think so too." Yuan Xiaoyi said softly, "She told me how to find her, she definitely wanted me to go and bring her back, but I don't understand, why... why..."

Hearing this, Jiang Cheng's eyes lit up, "Xiao Ting told you how to find her?"

"Yes, she told me that she was trapped in the medical building. If I want to see her, I can only do what she said."

"And I can't make any mistakes, otherwise I will be left there forever, just like her."

According to Jiang Cheng's understanding, what Xiao Ting said should be the rules in the mission, but this rule only applies to the medical building.

By analogy, the swimming pool, the abandoned playground, the sculpture hall, and the library all have corresponding rules, just like the side quests under the main quest.

Seeing Jiang Cheng's expression, Yuan Xiaoyi recalled what Xiao Ting said last night and slowly said, "First of all, you have to go to the medical building at night. Normally, the medical building closes at 8 pm, and there are special teachers responsible for locking the doors, but Xiao Ting told me that from 12 o'clock sharp, the medical building will become different from before, like... like entering another world."

"And to enter this world, you have to keep pulling the door of the medical building with your left hand at midnight sharp."

Speaking of this, Yuan Xiaoyi paused and explained, "The design of the medical building's door is a bit strange. Normally, it can only be pushed open. It can't be pulled open by pulling it outwards."

"So, if you can pull it open, it proves that you have entered another world." Jiang Cheng nodded. He had heard similar statements before.

In feng shui, this is called a trapped dragon formation, also known as accumulating evil. In some evil places, under the guidance of experts, the door is designed to only be pushed open from the outside, but not pulled open, which is equivalent to trapping the things inside.

Because the "people" inside cannot push the door open from the inside, they cannot leave.

"What do I need to do after entering?" Jiang Cheng asked.

Yuan Xiaoyi motioned him not to rush, "Not far from the entrance is the guard room. There is a list of visitors inside. You need to sign the visitor's name on it."

"Only in this way, it is equivalent to being recognized by the things inside, otherwise terrible things will happen once they are discovered."

"There are similar places for signatures on each floor. What you need to do is to find the signature place on each floor, then leave your name, and finally leave within the specified time."

The rules are not difficult, but it is hard to say whether something will go wrong in the actual operation process.

And Jiang Cheng was sure that it was definitely not that simple. He tilted his head to look at Yuan Xiaoyi and asked softly, "How long is the specified time?"

"44 minutes." Yuan Xiaoyi said definitely, "You must leave the building at 12:44 midnight through the door you entered. If you succeed, it will be considered a success in breaking this urban legend."

"I think Xiao Ting was trying to break it, but she didn't succeed." Yuan Xiaoyi's face showed a look of self-blame. After all, she asked Xiao Ting to go to the building in the middle of the night to take pictures.

Jiang Cheng supported her shoulders and said gently, "Xiao Yi, the fact that you can tell me these things shows that you are already a strong girl. I promise you, I will do my best to save them."

"Thank you, senior." Yuan Xiaoyi nodded repeatedly, her eyes full of gratitude.

"By the way." Jiang Cheng changed the subject, as if he suddenly remembered something, and asked Yuan Xiaoyi, "Before you said that Xiao Ting told you how to save her, but you said you didn't understand, and kept asking why, and you looked very sad, what's going on?"

"Senior, it's like this, although Xiao Ting told me how to save her, but she... but she doesn't agree with me going to save her!"

"She doesn't agree with you going to save her?" Jiang Cheng was a little surprised.

"Yes, she warned me that if I went, and entered the medical building, then everything would be over, everyone... everyone would die!" Yuan Xiaoyi said urgently, "Not just her, Xiao Ran, Xiao Hui and the others too!"

Hearing this, Jiang Cheng fell into thinking. If the girl in front of him was not lying, then he thought it might be like this.

To verify this guess, Jiang Cheng first comforted Yuan Xiaoyi a few words, then changed the subject and asked, "Xiao Yi, only Xiao Ting came to you last night, right?"

"Yes... yes."

"It seems that's the case." Jiang Cheng's expression was normal, and he probably understood what had happened.

Judging from the currently known clues, the old man's granddaughter they were looking for this time is among the 5 missing girls.

But who it is, is still uncertain.

And Yuan Xiaoyi is the means for them to contact the missing girls. They need to gradually learn the clues of the missing girls from Yuan Xiaoyi, as well as what the urban legends that trapped them are like, and most importantly, the method of rescue.

So Yuan Xiaoyi can't have any accidents, unless it is absolutely necessary, otherwise even if they all die, they can't take Yuan Xiaoyi to take risks.

Because once something happens to Yuan Xiaoyi, it is equivalent to cutting off the information transmission between them and the missing girls, and the mission will fail.

Thinking through this, Jiang Cheng's eyes towards Yuan Xiaoyi became more sincere, "Xiao Yi," he stretched out his hand to help the girl in front of him tidy up the broken hair around her temples, and the sense of distance was just right, "I hope you understand, just let me do the thing of finding your friend, as long as I am still here, I will not allow any woman to take risks in front of me, this is my principle."

He paused and said softly, "Especially you."

The sudden feeling made girls like Yuan Xiaoyi at a loss. She couldn't understand how there could be such a kind man in the world who not only agreed to help her find her missing friends, was willing to believe her unconditionally, and even wouldn't allow her to take risks.

"Senior, I... I really don't know how to thank you."

"There's no need to say thank you between you and me." Jiang Cheng took the time to glance outside the grove. Through the gaps between the branches, he could see Gao Yan and a few others gathered together, their faces gloomy, not knowing what they were plotting, but it was necessary to guard against them.

Yuan Xiaoyi noticed Jiang Cheng's actions and followed his gaze, asking curiously, "Senior, what are you thinking about?"

Hearing this, Jiang Cheng turned his head, shook his head with a wry smile, and moved his lips as if he wanted to say something, but in the end he didn't.

Yuan Xiaoyi saw a trace of helplessness and bitterness in this man's eyes.

"Senior, you must have something to say." Yuan Xiaoyi asked, "Is it related to your friends outside? If you don't mind, you can tell me."

Jiang Cheng pursed his lips, then breathed out, "Xiao Yi, to be honest with you, not all the people outside are my friends, and just because of helping you find your friend, I have been resented by some of them, they dislike me for meddling in other people's business."

"Did you see those two people?" Jiang Cheng took Yuan Xiaoyi's hand, and through the gaps between the leaves, pointed to Gao Yan, who was still chattering, and Wang Qi, who was standing not far away like a ghost, and said solemnly, "You must be careful of these two people. I'm not afraid of them excluding me, but I don't want to see them exclude you like they exclude me."

"Are they the ones who are excluding you, senior?" Yuan Xiaoyi remembered the faces of these two people.

She didn't want to pay attention to the people who excluded her senior at all, and even a trace of hatred spread in her heart, "Senior, I only believe in you!"
