When they arrived at the back door of the school, the back door had been locked and sealed. Ma Tianxi walked closer and looked at it for a while. The seal looked a bit old, and the handwriting on it became very blurred.

Zhang Bin pointed to the back door and said, "Just behind this door is our secret base."

Ma Tianxi frowned: "Isn't this door closed? How do you usually get through?"

"Climb." Zhang Bin pointed to the wall and said, "The wall here is not very high, and all the students in our class can climb over it."

Can they all climb over? Ma Tianxi hesitated. The height of the wall here is about 2.5 meters, and it is not necessarily impossible for him to climb over. However, there are also fine glass on the wall. If he climbs by himself, he might fall down directly after scratching his hand.

Just as he was about to ask if there were any other routes or other places related to the secret, Li Sen suddenly shouted: "Uncle Ma, look, Xiaomei's card was sent to her by me. She must have gone to the secret base behind, and I must go to find her right away."

Ma Tianxi didn't expect such a situation to happen. Looking at Li Sen's firm expression, he knew that even if he couldn't get over, he wouldn't be able to get over it. This child named Li Sen was very stubborn. Now he decided that Wang Xiaomei was right behind him. He wouldn't listen to him no matter how he said it. He would definitely go there.

There was no other way, and Ma Tianxi turned his gaze to the back door again. He looked carefully and then found that the lock on the back door was already rusty.

"Let's climb over now." Zhang Bin said, and at the same time he had already walked to the side of the wall. It seemed that he really had a way to climb over the wall here.

Li Sen is also eager to try.

Seeing that these two people were about to climb out, Ma Tianxi hurriedly spoke to stop them, "Don't worry, maybe we have other ways to go over it. Look at the door locks on it, there is so much rust. As long as we find a stone to hammer it, we might be able to open the back door."

Li Sen and Zhang Bin also felt that what Ma Tianxi said made sense. If they could walk directly over, they would not have to crawl over. After all, crawling is not a very comfortable thing.

Zhang Bin quickly found a stone and handed it to Ma Tianxi, obviously asking him to smash the door. In fact, the door locks have been rusted to this shape, so it doesn't matter who will smash the door lock.

Ma Tianxi didn't think so much. He just thought it was because Zhang Bin was weak and could not break the door lock.

This door lock is easier to open than Ma Tianxi thought. He didn't use much effort, and the door lock fell off. Ma Tianxi was also a little surprised at this, but soon he understood.

The door lock here has obviously been a few years old and probably has no effect anymore, so the door lock can easily fall off with such a light force.

Seeing that the door lock had been opened, Ma Tianxi didn't think much about it. He simply tore off the seal on the door, opened the back door of the school, and walked out with his two children.

In front of them was a very dilapidated hut, and behind them was a continuous mountain, but the dilapidated hut seemed a little abrupt. If it was the place of the school, why should it be built at the back of the school? But if it was not the place of the school, why should it be built in this place where people obviously could not live?

There are many strange pictures on the walls of the dilapidated hut, but because of the age, I can't see anything anymore. Only the bright and abnormal pigment still looks very ferocious.

Looking at these things, Ma Tianxi was stunned. He never thought that he would encounter such a situation. The existence of this small broken house seemed particularly terrifying in abrupt manner, making his scalp numb.

"What the hell is this? How could there be such a small broken house?" Ma Tianxi stood there, without continuing to move forward. Maybe he also noticed something was wrong.

Zhang Bin said casually: "Uncle Ma, there is nothing strange about this, it's so close to the school, and it's no big deal to have a custody room."

Ma Tianxi nodded. He had no other way than to believe these two children. But what he didn't notice was that Zhang Bin's tone of speaking at this time was really strange, and it didn't look like the tone of a child at all.

"Let's go, let's go." Li Sen urged: "There is nothing good to see here. Let's go find Xiaomei first, Zhang Bin, where is the secret base you mentioned?"

Zhang Bin explained: "It's soon, we will see the secret base soon. Don't worry. By the way, Uncle Ma, do you want to go into the warehousing room and take a look? I heard that no one has been in here for many years. Don't you also like adventures? Maybe you can find something different."

Ma Tianxi shook his head in a panic. He didn't want him to go in and take a look at it at all. You can tell at a glance that this place is not a good place. Maybe there will be something inside that he doesn't want to see. At that time, wouldn't it be very unlucky?

Ma Tianxi, who thought of these things, immediately rejected Zhang Bin: "There is no hurry to do this. Let's go to your secret base first. No matter what, we still have to find Xiaomei first. She is a girl who stays in such a dark place. If she has been in a dark place for too long, she will definitely be afraid."

Ma Tianxi was stunned for a moment when he said this. He suddenly thought that he seemed to have overlooked a very important thing. That is, how could a girl like Wang Xiaomei, who doesn't like to talk, make such a joke with them?

Originally, he thought that the girl might have just gone back early, but Li Sen just said that he saw Wang Xiaomei’s hairpin, which means that this girl is indeed here.

So...why is she in this place? Could it be...

Ma Tianxi shivered. When he thought of the situation he was most afraid of, his mind became completely gone. Looking at the small hillside in front of him, he felt gloomy.

Zhang Bin seemed to have no abnormality, but instead walked to the front and started to lead the way. Ma Tianxi had no other way now, so he had to follow Zhang Bin.

Just as they passed by the utility room, a "clang" sound suddenly sounded.
