found that he judged that Cheng Mo was right, and did not immediately return to his body, but opened the door and walked out of the classroom, using skills to vaporize the water in his pants and shoes, and then returned to his body.

According to his plan, if the other party has not yet appeared, his carrier will carry the body into the classroom, quietly waiting for the other party to come, and activate the carrier just to judge whether the other party is now in the classroom through the thermal imaging on the holographic map, Cheng Mo does not plan to let the other party see his carrier, not to mention that the other party is likely to be "Shen Daoyi", in case it is really Shen Daoyi, he has no way to explain why Lin Zhinuo appeared in school.

Cheng Mo didn't want Lin Zhinuo and Teacher Shen to have more intersections.

After the carrier disappeared, Cheng Mo stood up from the corner of the wall where he was sitting, his pants and shoes made him feel a lot better after they dried, and he walked lightly towards the staircase, the lack of water in his shoes made him walk lightly, as if he was free from gravity.

When he reached the exit of the stairwell on the second floor, Cheng Mo leaned against the wall on one side and hesitated for a moment, but soon he took a deep breath, tensed himself and walked into the corridor along the corner.

The heavy rain outside the school building obscured his insignificant small noise, so everything went smoothly, and soon Cheng Mo walked to the back door of the classroom, the wide silver aluminum alloy window appeared in his field of vision, through the glass, he could see a woman in a black tight leather coat standing in front of the blackboard drawing.

At this moment, the rolling dark clouds outside were very low, and the wind swept the broken raindrops and smashed them on the glass windows outside, crackling, and then flowing into patches of tears; the blue-yellow plane trees trembled in the wind and rain, and the yellow leaves were knocked down by the wind and rain, and half of the branches were bald; the mountain dailies in the distance were just a dark silhouette in the majestic rain curtain, and the dense dark clouds were connected to cover the whole world.

The women in the classroom stood on the podium, drawing chalk drawings and singing songs, their voices ethereal like distant and bleak birdsong in the wind and rain.

The amazing winding back is undoubtedly Shen Daoyi. ("Ronin Pipa" Hu Liuliu)

"Xiaosheng's flower umbrella is still at your house

You are as beautiful as a flower

I've wandered the world

Make me a cup of flower tea

It's a little out of touch with you

The atmosphere was starting to get a little awkward

You smile shyly

It's so harmonious

I can't help but worry about you

What era

I didn't want to go home for a long time......"

The non-stop sound of the rain is like a band accompaniment that will not be interrupted, combined with Shen Daoyi's graceful shallow singing, summing up the sorrow and warmth of life, although there is no coordination of musical instruments, the sound of nature is not inferior to excellent performers, of course, the most important thing is that Shen Daoyi's voice is so good, like the sun washed by the spring rain, the brightness is mixed with a touch of decadence, sad but not sad, like shining through the rain curtain of the sun.

Cheng Mo stood quietly at the window at the back of the classroom, watching Shen Daoyi draw a shallow pond on the blackboard, a woman with a wide untie and a peeping boy......

She sang the same song over and over again, but this simple tune made Cheng Mo feel tired of listening to it, her voice was like cotton cloth soaked by rain, all the phrases were full of inexhaustible moisture, her green hands and slender waist swayed in Cheng Mo's pupils, and the beautiful rhythm filled every cell around him.

Shen Daoyi's voice swirled in Cheng Mo's mind, he closed his eyes, and wanted to find the exact words to describe it, but he couldn't find the right words.

Cheng Mo just felt that this scene was a little lonely.

Lonely, but not sad.

I don't know how long it took, Shen Daoyi turned around to get the chalk box placed on the podium, so he saw Cheng Mo standing by the window outside the classroom like a ghost, if Shen Daoyi was a student who liked to desert in class when he was studying, and recalled the fear of being dominated by the face of the head teacher who quietly appeared by the window when he was in school, he would definitely have a deep shadow on this scene.

But obviously, Shen Daoyi is not.

She smiled at Cheng Mo and said, "You're here?"

Cheng Mo didn't hear Shen Daoyi's voice, he just judged the three words she said by the shape of his mouth, as for the tone of the last question, Cheng Mo was not sure if there was any, maybe there was, maybe not, but it didn't matter.

Cheng Mo walked forward along the corridor, walked to the front door of the classroom, and knocked politely, like an unexpected guest.

Soon the light yellow wooden door painted with wood grain paint was opened, and a long "squeak" sounded in the empty corridor, and then Shen Daoyi appeared in front of Cheng Mo, she was wearing a black tight-fitting one-piece leather suit, the silver zipper extended from the neck to the waist, as if inlaid in the skin, the tight leather pants were still shiny in the dark sky, wrapping a pair of legs extremely slender, and the high-heeled boots made the legs show an amazing beauty, like a peerless murder weapon.

There was a silent humidity in the air, and the raindrops washed this filthy world, and Cheng Mo's gaze crawled along Shen Daoyi's line of sight, freezing her in a faint arc of light......

"Come in!" Shen Dao turned to the side and opened a wide gap for Cheng Mo, as if she was standing at the door of her house now.

Cheng Mo glanced at the chalk that Shen Daoyi pinched in his hand, and then glanced at the camera behind the classroom, the red eyes around the lens were dim, obviously there was no electricity, Cheng Mo walked into the classroom without saying a word.

Shen Daoyi doesn't need to be afraid of the monitoring in the teaching building at all, the monitoring of the teaching building is all turned off on weekends, in fact, if it weren't for the "painting of the secret room" incident, the people in the security department would not turn on the monitoring in the teaching building at night, after all, there is really nothing to steal in the classroom, there is no need to waste electricity.

This is the accurate news that Cheng Mo got from Director Wu's mouth.

Cheng Mo quickly stopped, stood under the podium and looked up at Shen Daoyi's unfinished chalk drawings.

"Cheng Mo?" Shen Daoyi accurately threw the chalk in his hand into the chalk box placed on the podium, and asked with a smile.

Cheng Mo said "Hmm!", Shen Daoyi propped up his hands slightly, sat on the desk beside Cheng Mo, and said with interest: "After waiting for so long, someone finally came..... To be honest, Changya is really a place to destroy people, so the students here are really boring!" Then she turned her head to look at Cheng Mo, raised her hand and nodded on her chin, "But fortunately, there are still strange things like you, otherwise it is estimated that they will suffocate ....."

Cheng Mo didn't speak, still looking directly at the blackboard drawings that had been outlined on the blackboard.

"How did you know that I had finished painting in the afternoon?" asked Shen Daoyi, who was taking the school exam.

Cheng Mo turned his head and looked at Shen Daoyi and said lightly: "There are only so many types of secret rooms, your kind of secret room is a combination of psychological action type and special skill type, you deliberately created the phenomenon that you must make the painting appear when the monitor is restarted, which is to mislead and make everyone think that you must need to restart the time to complete the chalk drawing..... Actually, you don't need to ..... at all It's a psychological chamber...... So the drawing must have been on the blackboard for a long time, not suddenly in the time of restart....."

"Really, then how did I make the chalk drawings appear out of nowhere?" Shen Youyi asked with a wink at Cheng Mo.

"Invisible Scratch..... The vast majority of people do not know the principle of chalk words appearing on the blackboard, in fact, the chalk composed of calcium carbonate (limestone) and calcium sulfate (gypsum) can leave clear handwriting on the blackboard because there are countless fine holes on the blackboard, and those powders are filled into those holes that are imperceptible to the naked eye, leaving traces..... And it won't be evaporated by the intense sunlight that will volatilize when exposed to heat....."

Although Shen Daoyi knew that Cheng Mo had solved the puzzle, he still shrugged his shoulders and asked with a smile, "Then how did I make the invisible slash disappear at the time I wanted?"

"It's simple. Cheng Mo turned his head to look at the air conditioner on the side of the classroom, "You will set the air conditioner in the right place, adjust the air outlet to face the blackboard, you hide outside the classroom and see the red dot on the monitor disappear, you know that the other party has turned off the monitoring, so you will press the air conditioner switch, you don't need to enter the 'secret room' at all, you can make the picture appear on the blackboard......"

Shen Daoyi sat on the desk and applauded, chuckled and said, "Cheng Mo, it's really exciting..... Analysis in detail..... Now that you've caught me, don't you have any questions for me?"

"Of course, why did you do this, and what was your motive?" Cheng Mo asked solemnly as he stared at Shen Daoyi's identical face to Teacher Shen.

Shen Daoyi jumped off the desk, the tight waves bounced twice on her chest, she walked towards the door of the classroom, took two steps and turned in a circle, and spread her hands in front of Cheng Mo, "Of course it's because it's boring! You see that this school is full of sanctimonious defenders, they are called human soul engineers, known as hard gardeners, and praised as the loveliest people..... However, what they do is put into a mold of different souls that are supposed to be interesting, and shape them into the same shape..... Those free souls are indoctrinated with all sorts of dogmas and rules, making their minds rigid, their vision short-sighted, and their vision narrower..... A good educator should educate one child in 50 ways of education, not 50 children in one way of education..... So I'm going to give them the sharpest sarcasm ....."

Cheng Mo shook his head, "No, maybe you think so, but you're not your motive....."
