After doing these things, Yuan Ye quickly restored the slate to its original state, picked up his schoolbag and fled, and fled far away to the corner of the playground, only then did he gasp and untie his clothes, letting the morning breeze blow away the stench on his body.

When the smell on his body became bearable, he took out his mobile phone, dialed Zhao Delu's phone, and told his cousin the news that the matter was done.

"If you forget about it, you don't think it happened. Zhao Delu instructed, and then hung up the phone. Yuan Ye looked at the teaching building in the distance inexplicably, and couldn't figure out why he did such a disgusting thing.

As soon as the time passed eight o'clock, there was already a commotion on the first floor of the teaching building.

Someone ran out of the toilet and screamed that there was stinky water everywhere. Someone flew to the logistics office, and the director of the logistics office who had just gone to work came to check it and asked the students to go to class first, and he would contact him to deal with it.

The call went to the municipal service company. Of the four pipeline dredging vehicles on the other side, two had already been called to dredge the pipes early, and one had an inexplicable failure and could not be started.

Fortunately, there was still a dredging truck on standby, and ten minutes later, the pipeline dredging truck slowly drove out of the parking lot and headed towards Jiangbei No. 1 Middle School.

There weren't many vehicles in the morning. The dredge truck was driving on a wide road when suddenly a black Nissan squeezed up from behind and pressed in front of the dredge, as if trying to turn right at the next intersection.

The driver of the dredging car impatiently honked the horn. The Nissan driver in front of him reached out of the window with his left hand and raised his middle finger in an insulting gesture. The driver of the dredge truck was furious and continued to press the horn frantically.

The Nissan car in front of it braked suddenly. The driver of the dredging car was shocked and hurried to hit the brakes, but unfortunately it was too late. Just listen to a loud tom, the front face of the dredge car has hit the rear of the Nissan car, knocking it out seven or eight meters away, and the bumper at the rear of the car has been smashed to pieces!

The Nissan driver jumped out of the car, rushed to the back of the car, looked at the smashed rear of the car, and began yelling at the dredge car. The driver of the dredge truck shouted bad luck, pushed the door and got out of the car, and quarreled with the driver of the Nissan car in front of him.

At the next intersection where no one was paying attention, a pipeline dredging truck quietly turned around and had already driven in the direction of Jiangbei No. 1 Middle School.

The entrance of No. 1 Middle School. The driver of the pipe dredging truck honked the horn, and the security guard came out of the house to look at it and press the button to open the closed automatic gate. The driver stuck his head out of the cab window and shouted, "You guys here are reporting a fault, let's come and dredge it!"

"Wait a minute!" the security guard ran into the house to make a call. Half a minute later, he ran out of the room and made a passable gesture and pointed in the direction behind the school building.

The pipeline dredge truck slowly drove into the school and stopped in the corner of the school building. Two workers in overalls got out of the car and inserted a long pipe into the septic tank entrance at the back, and a machine rumbled and began to work.

After a while, it didn't seem to have any effect. Two staff members carried a large basket up the stairs of the school building and began to inspect each bathroom at the top of the hallway, floor by floor.

The time soon came to ten o'clock, and it was already big recess time. The corridor of the teaching building was full of students who came out to let off steam, and the entire side of the teaching building was full of life, like countless sparrows gathering together to chirp and cheer.

Lin Can slipped out of the classroom to breathe. He staggered around the corridor and came to the front class, just in time to see Zhou Tieniu, Wu Youzhi, and Wang Dequan standing in front of the railing and laughing.

Walking among a few people, Lin Can smiled and asked, "So happy, what happened?"

"Brother Can, you give me a comment. Wu Youzhi grabbed Lin Can and stretched out his hand to the pipe dredging vehicle in the corner of the teaching building: "I said there was a problem with the car, but they all said I was insane!"

"A pipeline dredging vehicle~" Lin Can looked over, and sure enough, he saw a car parked in the corner of the teaching building, making a slight rumbling sound.

"I didn't see anything wrong~" After watching it for a long time, Lin Can didn't find anything abnormal, turned his head and asked, "Where did you see that there was a problem?"

"Have an eye for detail. Wu Youzhi smiled proudly: "Brother Can, look at the man in work clothes." ”

Lin Can took a closer look, and sure enough, he saw a person walking around the car, took out a bottle of mineral water and drank a few sips, then left the vehicle and walked into the teaching building again.

"Are you saying that person doesn't work well during working hours?" Lin Can felt inexplicable.

"Look at his overalls. Wu Youzhi said firmly: "There is a problem with this person's identity, his work clothes are too clean! The dry pipe is dredged, that clothes are not black and dirty? And his gloves are so white, cleaner than the waiter at the door of the hotel lobby!"

"That's not right!" Lin Can suddenly felt uneasy in his heart, as if something terrible was happening. His mind was spinning, and he suddenly turned around and ran, slamming into his classroom!

There were few people in the classroom, and Wu Siyi was nowhere to be seen. Lin Canfei ran to the last row of Luo Li and asked loudly, "Do you see Wu Siyi?"

"Did you go to the bathroom?" asked Lori in surprise, "What are you looking for her?"

"It's broken!" Lin Can didn't have time to elaborate, and said quickly: "There may be bad people who have mixed up in the school and want to be unfavorable to Wu Siyi! You should go to the toilet at the end of the corridor immediately now, and find out if Wu Siyi is inside!"

"Are you overreacting......" Seeing Lin Can's unkind face, Luo Li closed her mouth and ran out. When Lin Can came to the corridor again and returned to Zhou Tieniu and them, Luo Li had already rushed over from the end of the corridor and shook her head at Lin Can!

"Bad thing!" Lin Can's face turned pale, and Zhou Tieniu was scared. Everyone gathered around and asked, "Brother Can, what's going on?"

"It's too late to explain now, you all listen to my arrangement!" Lin Can looked at a few people around him: "Tie Niu, Youzhi, you are in a group of two, Xiaoli and Dequan, you are in a group of two." You go to the two entrances and exits on the first floor of the teaching building, and if anyone leaves with a container or something, be sure to check carefully to see if there is anything suspicious!"

The three boys didn't understand, but Lori had understood everything. She stared at Lin Can and asked, "How do you do it?"

"Search next to the floor!" Lin Can waved his hand suddenly: "Hurry up, Xiaoli, you go and guard the passage near the dredge car!"

The four of them flew away. Lin Can ran to the stairs on one side and flew down to the first floor, shouting in front of the women's toilet at the end of the corridor: "Is Wu Siyi there, if you are there, say yes!"

No one responded. He went up to the second floor and asked in turn, all the way to the fifth floor, the highest floor of the school building.

It's already a large conference room and equipment room, and there are not many people staying here. Lin Can finished asking loudly in front of the toilet on one side, and then rushed through the corridor to the other side and shouted loudly.

No one agreed. He was about to rush downstairs when he suddenly heard a slight noise from the women's toilet, which seemed to be a female voice moaning softly.
