Zhang Chengyuan was really calm this time, he trained hard for several days in a row like before the incident, and mingled with his partners. Only then did he realize that it was not easy to control his emotions and tolerate things in his heart, but when he really had this ability, he found that it was actually a very interesting thing.

Zhang Chengyuan was silent for half a month. In fact, if other factors are not considered, he can wait longer. He knew that Principal Yu must have been a decoy to keep his mother here, in order to lure out more defectors, so his mother's own safety was not a problem. He was worried about his father, because although he was not an impulsive person, it was impossible for him to be indifferent to his mother's arrest, and he was afraid that his father would not be able to hold his breath before him, and he would take action to rescue his mother and then fail.

So on this day half a month later, he had already stepped on the table and chair, opened the vent shutters in his room, and climbed in.

Zhang Chengyuan climbed very slowly, firstly, because the iron plate on the wall of the ventilation duct was not very thick, and it would make a sound if it was louder, and secondly, there was no light source inside the ventilation duct, only bright light would be projected through each shutter leading to each air outlet. Zhang Chengyuan instinctively climbed in one direction, and Zhang Luoqi's words kept echoing in his mind: "One of the two most accessible passages in the world is the sewer and the other is the ventilation duct." One connects the rest of the city, and the other connects the inside and outside of the building. ”

At this time, Zhang Chengyuan had already decided in his heart that although he didn't understand why Zhang Luoqi would tell him this, but when he started playing the two-way mirror, he had subconsciously trusted Zhang Luoqi.

After turning the direction a few times, Zhang Chengyuan couldn't tell the difference between southeast and northwest, but he didn't get lost. In the ventilation duct, you don't need to worry about the southeast and northwest, just climb against the wind.

Finally found the upward passage, Zhang Chengyuan fumbled for the steel welded ladder, and climbed up in the not spacious ventilation duct. In fact, this was not as dangerous as he imagined, because in the process of climbing up, his back was against the back wall of the ventilation duct, and even if any steel bar was really unreliable, he would not be in danger of falling to his death.

It was snowing, Chen Jiatong turned off the lights in the bedroom and looked out the window, and the street lights illuminated the playground covered with silver ribbons under the starry sky. Because the weather was too cold, there were no students walking around the playground at night, and the snow covered in the playground was as smooth as a bucket of freshly opened ice cream.

Thinking of this, Chen Jiatong almost drooled, she hadn't eaten a bucket of ice cream in two years. She playfully closed her eyes and stuck out her tongue to lick it in the air, imagining the taste of cold, sweet milk ice cream. When he opened his eyes again, Chen Jiatong was indeed surprised to find that there was an extra scratch on the mirror-like snow on the playground, destroying the perfect mirror surface. It's like someone scratching a freshly opened vat of ice cream with chopsticks.

She couldn't believe that there was such a coincidence, she closed her eyes and made a small gesture of licking ice cream, and a trail appeared on the snow surface of the playground from the other side of the trees to the side of the dormitory.

"Knock knock!" The knock on the door suddenly sounded, and Chen Jiatong was even more shocked.

Looking back from the snow outside the window, Chen Jiatong walked quickly to the door to open the door, her heart was beating happily, and her intuition urged her to open the door quickly.

Open the door.

Zhang Chengyuan flashed into the house like a thief and closed the door with his backhand.

In the next second, he hugged Chen Jiatong tightly with his shivering body.

Chen Jiatong also hugged Zhang Chengyuan tightly, using her warmth to thaw the exhausted soul.

Neither of them spoke, Zhang Chengyuan's heavy and rapid breathing gradually eased, his body was warmed, but the side effects of using the cold time followed, and the fatigue rushed back to Zhang Chengyuan's body like an evening tide, immersed in every joint of his body, and with every breath, his lungs were in severe pain.

Chen Jiatong felt his tiredness, helped him sit on his bed, and then like a quiet cat, he gently leaned his cheek on Zhang Chengyuan's shoulder.

Zhang Chengyuan gradually adapted to the tiredness of his body, turned his head, and gently clasped his hands on Chen Jiatong's shoulders.

The street lamp outside the window shines into the window under the reflection of the snow, adding a touch of romance to the bedroom.

Zhang Chengyuan breathed the air greedily, and the room was full of Chen Jiatong's smell.

Chen Jiatong lowered his head and smiled sweetly.

"What are you laughing at?" Zhang Chengyuan asked gently.

"You must want to say, you miss me~" Chen Jiatong raised his head playfully and stared at Zhang Chengyuan's eyes with a little embarrassment.

"How do you know?" Zhang Chengyuan really wanted to say that.

"Because I miss you too!" Chen Jiatong said, pursed his lips, and lowered his head.

Chen Jiatong suddenly stretched out his right hand to block Zhang Chengyuan's mouth.

"What?" Zhang Chengyuan blocked Chen Jiatong's hand. I wanted to kiss her, but she blocked her mouth with her hand first.

"I'm in a bad mood, I won't let you kiss~ I was sick a while ago, and you didn't come to see me!"

Holding Chen Jiatong's soft hand, Zhang Chengyuan asked pityingly, "What kind of disease?" How's it going? ”

"Very strange sickness. Every day in the classroom, I feel uncomfortable, my mind is very confused, I often slip in class, and it is difficult to concentrate. After a long time, your head will hurt very much, just like the feeling of staying up all night for two or three days in a row to do three-dimensional geometric calculations. But I clearly got enough sleep, and I didn't pay much attention to theoretical knowledge...... What's even stranger is that whenever I feel like I can't bear to take time off work to recuperate in the dormitory, the symptoms of discomfort will disappear quickly. But every time I go to the classroom again, I immediately feel surprisingly uncomfortable. ”

"Should you ......," Zhang Chengyuan interjected with a smile.

"I'm not tired of studying! Seriously, I'm not kidding you! Chen Jiatong said a little angrily.

"I ......," Zhang Chengyuan wanted to defend.

"Don't explain...... I won't really blame you~Ah! Although I was very happy to see you, you came out ......."

"I ......" Zhang Chengyuan was trying to explain his experience to Chen Jiatong.

"Vents? You, you came out of the vent this time? Okay, that's amazing, how did you come up with that? Chen Jiatong asked curiously.

"Chen Jiatong......" Zhang Chengyuan's eyes were surprised: "You, how do you know what I'm going to say?" ”

"What, what are you going to say?"

"Every time you don't even have me to say anything, you know what I'm going to say? You! Can you read minds? Zhang Chengyuan could hardly imagine other reasonable possibilities for a while.

Chen Jiatong's expression began to become wooden: "Just now, you said that you came out of the vent this time...... You, didn't you say this yourself? ”
