The sun and the moon are flying.

In the blink of an eye, it was a month later.

Xiangbei specially recruited the top class of Sany Academy and devoted himself to the practice of the War Card Master. The so-called stupid bird flew first. Although Xiangbei started late, he had the unique tenacity of the mountain people.

The strength of training is rapidly improving day and night.

Every weekend, Lin Dong would meet up on Baicheng and listen to the experiences in the academy and give some guidance on the direction of practicing northwards.

In a month, Lin Dong used his identity as a teacher to explore most of the college. He kept entering and leaving the college with thick black-rimmed glasses and cleaning tools.

It's like a ghost that everyone can see but no one cares about. No one knows who he is, and no one remembers him, caring about what he is doing.

Sany College is very big, and Lin Dong's exploration speed is not slow. In one month, he has found out and investigated 99% of the places in the college.

In addition to the No. 7 experimental building.

There are many students in the college and the teaching atmosphere is very open, and few places are strictly controlled.

But here is an exception.

To enter this inconspicuous building, you need to go through layers of secret levels. What Lin Dong most doubts is that this small building with only two floors has hundreds of people entering and leaving every day. How can such a small place accommodate so many people?

Moreover, once these mysterious people walked out of the No. 7 teaching building, someone would follow them. They didn't go anywhere except the dormitory and the experimental building. Everyone was ashamed of water and rarely spoke to each other.

All of this is very suspicious.

Lin Dong wanted to get close to this place several times but failed. Among the many teachers and staff, no one could enter the place except for one mute Liu Er.

Lin Dong spent a week getting close to the mute Liu Er, treating guests to dinner and going to the show together.

Lin Dong intentionally or unintentionally mentioned the mysterious teaching building No. 7 mute, who waved his hands repeatedly, and interrupted Lin Dong, as if he was unwilling to mention it.

It was already dark, and Lin Dong appeared in the room of the mute Liu Er, a teacher dormitory building.

When he opened the door, the mute saw Lin Dong smiling, pointed to the chair and signaled Lin Dong to sit down, busy making tea for Lin Dong.

The mute has worked in Trinity College for more than 40 years, so his room is larger than the dormitory of other teachers and staff. There are two rooms, and his location is quieter.

A mute bachelor, the room was messy.

"Brother Liu, are you going to the No. 7 Laboratory Building tonight? I wondered why you always work and sleep during the day?" Lin Dong asked.

The mute waved his hand and made a helpless gesture, which meant "I don't want to do it either? That's what it is."

"I planned to go to Xiaoyao Tower with you tonight, but it seems that you will be able to go again." Lin Dong sighed while saying, looking at the mute reaction at the corner of his eyes.

The mute had no wife. When he talked about going to the brothel, he immediately thought of something, shook his head in pain, and refused Lin Dong's invitation.

"Brother Liu, I think you are working so hard, so why don't you go to work for you tonight. How about you go out and find two girls and have fun all night?"

Lin Dong had made up his mind, so he did not hide his words, but instead tried to test the bottom line of the mute.

The mute's face suddenly changed, showing a fierce look, but soon looked down and thought.

He nodded and raised his thumbs to Lin Dong.

agree?

The genius believes in you!

At this time, Lin Dong suddenly rushed to the mute with one step, pinched the mute's neck with his right hand and lifted him up and leaned against the wall.

The mute's face was full of shock, his face turned red, and his blood vessels surged.

Lin Dong carried the mute and came to a table in the corner of the wall like a chicken. He reached out and took out a clamping machine from under the table.

Lin Dong pinched the mute's neck tightly, "Brother Liu, I suddenly changed my mind. I originally thought you were just an ordinary mute, so I didn't want your life, but if you actually know martial arts, I can't blame me."

Since Lin Dong said he wanted to work for the mute, he has been looking at the table intentionally or unintentionally.

The mute's eyes were full of fear. He wanted to resist, but why was Lin Dong's opponent? The battle card division without any weapons was a dead person in the hands of Lin Dong, who had great power.

The mute was strangled by Lin Dong's throat and was extremely stuffy. He swung his arm desperately to hit Lin Dong, with cruelty in despair.

The fist hit Lin Dong like tickling it.

Scratch!

Lin Dong exerted force on his hand, and his mute neck was crushed to pieces. His tongue was spitting outside and turned purple. His head was hung weakly on one side, like a dead duck.

There was a large wooden box in the bedroom. Lin Dong hid the body in the wooden box and searched it indoors, but did not find anything special.

The mute usually works at 10 o'clock in the evening. At some time, Lin Dong brewed a pot of tea in the mute's room and waited quietly.

Just after nine o'clock, Lin Dong stood up and changed into mute's usual clothes, disguised himself a little, put a piece of gauze on his face, covered half of his face, and took the mute employee card and walked into the night.

The No. 7 Experimental Building is located in a desolate place in the college. It is surrounded by flat grass. Dozens of large-scale lighting equipment illuminate the surroundings. If you don’t want to attract attention, it is impossible to steal it into it.

Lin Dong walked towards the No. 7 Experimental Building with a hunched back with a hunched back.

There was only a chubby and cute guard standing at the door. Lin Dong knew that this was just an illusion, and countless pairs of eyes were looking at him in secret.

Fortunately, Lin Dong's imitation of the mute's actions were extremely clever and no one noticed that anything was wrong.

With his head down and facing the guard, Lin Dong walked directly into the door.

"Liu Er, you came early today. Do you want to finish work early and go home to hold your wife?" The chubby guard said teasingly.

Where did Liu Er get his wife? This is just teasing.

Scholar Lin Dong looked mute, sobbing in his mouth, and stomped his feet and walked into the door angrily.

"Why are you angry? You're not hit by your wife, right?" The fat guard continued to say to Lin Dong's back.

Mixed in!

Lin Dong was not relaxed. Where should he walk on the left and right passages? Or to the second floor?

Turn to the left habitually.

At this time, the fat guard at the door smiled maliciously and said, "Liu Er, are you confused, are you? The elevator is on the right. Haha."

right?

Elevator?

There are indeed underground buildings in this place!

Lin Dong looked angry again and pointed at the fat man hard and walked towards the corridor on the right.

There are six doors on both sides of this straight corridor.

Lin Dong put his pace very slowly and did not dare to enter any door at will. If someone found out, it would be bad.

He raised his ears and listened carefully. The rooms seemed to be empty. While he was hesitating, Lin Dong saw the words "The Utility Room" written on the door on the left.

Lin Dong pushed it with his hand, and the door was locked.

Take out the dumb employee card, insert it into the slot on the door and open the door.

This is a place where debris are piled up, and cleaning tools are also included.

Find the mop and bucket in the corner of the wall. In order to prevent Lin Dong from putting the kneading machine and the black snake sword in the bucket, he used a mop to cover the upper part of the bucket.

Bloodstains!

Lin Dong saw at a glance that there was still a trace of blood on the mop that had not been cleaned yet.

I put it on the tip of my nose and sniffed it.

"Human blood!"

It's weird, very weird. Why is there blood that has not been cleaned yet on the mop?

A bad premonition arose in Lin Dong's heart.

Close the door, Lin Dong leaned against the door and listened to the movements in the corridor.

After a while, a person's footsteps came and he was getting closer and closer.

“It’s now.”

Lin Dong opened the door and walked out of the utility room with a mop bucket.

I saw that the person who came was a young man in his twenties, wearing glasses, and seemed to be yawning before he woke up.

Seeing Lin Dong coming out of the utility room, the young man glanced at Lin Dong with the corner of his eyes. Who would care about a mute who cleaned up? Besides, Lin Dong has the ability to integrate into the environment, which is inconspicuous at all.

The man ignored Lin Dong and opened one of the doors.

Lin Dong took two steps to the door and looked inside.

There is nothing in this room except an iron door.

When the young man saw Lin Dong coming with a bucket, he kindly held the door with his hands and waited for Lin Dong to come in.

Without hesitation, Lin Dong entered the room.

I lowered my head and came to the only door inside. This door was made of heavy metal and there was a slot on the side of the door.

Lin Dong pretended to grop on his body.

At this time, the young man wearing glasses took out a card and inserted it into the card slot, and the iron door slowly opened.
