Compared with canvas, oil paper is cheaper and easier to handle, making it suitable for daily training for novices.

However, oil painting is a special type of painting. Art students usually need to have a certain foundation in art before they can start creating oil paintings. At this time, most of them are no longer interested in primary painting materials such as oil painting paper. So when Chen Ge saw the oil painting paper on the easel, he was a little confused. What kind of person created this work?

Chen Ge studied toy design and manufacturing in college and took some courses related to art and appreciation. He could see some clues from the other party's simple composition. The person who drew this picture was definitely not a novice.

"He seems to be constantly trying to express something." Chen Ge's fingers slid across the paper. The upper part of the paper was rough, while the lower part was smooth. The touch was completely different: "Why does he insist on painting in oil? Is it because oil painting can better express his meaning?"

Two upside-down wards, two patients who look exactly the same. There is no problem with the composition of the picture. Only when you touch it with your hands will you find that the materials of the upper and lower parts of the drawing paper seem to be different.

"This is an oil painting, do I need to put paint on it to see the difference?"

With the mentality of giving it a try, Chen Ge lifted the white cloth on the shelf and prepared to select paint.

The shelves are huge. The paints here are different from those sold in stores. They are all packed in glass cups without any trademarks or instructions.

"Why... only red?"

Looking at the rows of glass cups, Chen Ge stood there in a daze. There were all kinds of red on the shelves, but apart from red, there were no other colors here.

Reaching out and unscrewing the lid of the cup, a faint smell of blood wafted out. Chen Ge was sure that this was definitely not the smell that oil paint could emit.

"Just use it."

Chen Ge picked up the paintbrush on the easel and smeared the red liquid in the cup onto the canvas paper.

After the first stroke of the pen, Chen Ge noticed something was wrong.

There seemed to be an invisible dividing line in the middle of the paper. The dye in the cup only left a light red mark on the upper half of the paper, but left a dark red, hideous mark like a scar on the lower half.

After a few consecutive strokes, the painting on the easel changed its appearance.

The upper part seemed to be just a ward with a light red light, but the lower part seemed to be soaked in blood.

The patients in the painting have exactly the same expressions, but the feelings they give people are completely different.

One looked ordinary with a slightly confused expression, while the other was covered in blood, with hatred and resentment condensed on his face.

“Is this painting reflecting the world behind the door? Or is there another deeper meaning?”

After a few seconds, Chen Ge saw an even more magical scene.

The color of the upper part of that piece of drawing paper with a special material was gradually fading, while the color of the lower part was constantly deepening, as if all the blood color in the upper half of the painting had been poured into the lower half.

"Isn't that what the worlds inside and outside the door are like? The despair in reality keeps pouring into the world behind the door. One purifies itself, while the other becomes more desperate."

The more Chen Ge looked at it, the more he felt that the painting was related to the door. He tried to take down the painting, but he only took it halfway when he heard a knock on the door.

"That thing is coming?"

Chen Ge's hair stood up instantly. He decisively gave up on taking the painting away. He picked up a scrap of draft from the ground and trotted to the window.

Chen Ge had looked outside the building before entering it, and found that none of the windows had anti-theft nets installed.

Pulling aside the thick gray-black curtains, Chen Ge pushed open the window and was about to climb out when he suddenly saw a person standing downstairs.

The other person had his head down, was wearing leather shoes, was tall and thin, and looked very abnormal.

"Teacher Bai?"

Teacher Bai, who was originally guarding the boys' dormitory, appeared around the laboratory building for some reason. He seemed to be looking for something.

Chen Ge's body, which was about to flip out, retreated again. He pulled the curtains with lingering fear: "I was almost discovered!"

Looking outside through the gap in the curtains, I saw Teacher Bai walking around the laboratory building. He seemed to be hesitating whether to enter.

"If I jump from here, I'll land right on his face. What should I do?"

"Bang! Bang! Bang!"

The knocking on the door became more urgent, and Chen Ge was now in a dilemma.

His brain was working rapidly, but the thing outside the door didn't intend to give him much time.

The sound of the key being inserted into the lock was like a knife stabbing into Chen Ge's chest. He had no time to hesitate, as the door would be opened the next moment.

"Never mind, let's leave first."

Carrying his bag, Chen Ge stepped on the edge of the window.

If you can't jump down, then crawl to the sides.

He chose the right moment and moved to the windowsill of the next room.

"If it's hung outside, sooner or later Teacher Bai will see it. This location is too conspicuous."

Chen Ge held the air conditioner unit tightly with both hands. Before he could catch his breath, the door of the paint storage room was opened.

The person in the house seemed to see that the window was not closed and was walking towards the window!

The footsteps were getting closer and closer. At this moment, as long as the other party stuck his head out of the window to take a look, Chen Ge would be discovered.

"Go to the third floor!"

Gritting his teeth, Chen Ge grabbed the windowsill on the third floor with both hands and climbed onto the windowsill without any protective gear.

Just as he climbed onto the third-floor window sill, a pale arm stretched out from the window of the paint storage room on the second floor.

Chen Ge stood on the palm-wide windowsill on the third floor, not even daring to breathe too hard.

Maintaining this posture consumes a lot of physical energy, and if you lose your grip, you will fall.

Chen Ge tried to push the window on the third floor, and when he found it was not locked, he jumped in decisively.

Without having time to check what was in the house, he hid beside the window and watched Teacher Bai secretly.

"Why doesn't he leave?"

The third floor is the most dangerous floor. The elevator originally stopped on the third floor. When he took the elevator just now, the things in the elevator also ended up going to the third floor.

Chen Ge stayed in the corner without moving. He decided to wait in this room until Teacher Bai left before making his next plan.

The night wind blew into the house, and the bright red curtains fluttered across his neck. Chen Ge was about to close the window tightly when he suddenly remembered that the curtains on the second floor seemed to be gray-black.

His body paused for a second, Chen Ge took a few steps back, away from the window, then immediately opened the door and rushed out.

The corridor was pitch black, without a trace of light. The doors of all the laboratories on the third floor were open, and some were still creaking.

Gently closing the door behind him, Chen Ge went straight into the room on the other side of the corridor.

He thought about going out from the window of this room, which happened to be on the other side of the building, so he could perfectly avoid Teacher Bai.
