"No need, Mr. Zhang, you keep it to eat, I don't need to eat so much." Zheng Changyin hurriedly sandwiched all the meat back to Teacher Zhang.

"The teacher usually eats too much, but now he has to eat less."

"No, no, you still keep it, teacher."

Teacher Zhang and Zheng Changyin kept humbly for a few pieces of meat.

In the end, Zheng Changyin still did not accept Mr. Zhang's kindness, and each ate his own share of meat.

At this meal, Zheng Changyin ate with mixed feelings. In the past, when I was in the Zheng family, I had to rob others to grab meat to eat. Now, someone offered to let her eat it. Zheng Changyin felt lucky, fortunately there was a college entrance examination, passed the college entrance examination, and left that place.

Now Zheng Changyin has no nostalgia for that place. Zheng Changyin secretly thought that he must find a way to persuade his mother and take her out as well.

Early the next morning, five participating students and five school personnel had already come to the reception hall to wait.

Fang Li's gaze glanced at Zheng Changyin from time to time. I saw that Zheng Changyin was full of energy, and it didn't seem like he had eaten the wrong thing at all.

Fang Li wondered in her heart, could it be that Zheng Changyin didn't have dinner yesterday? Or maybe you didn't have any soup? Yesterday, Fang Li put a special laxative in Zheng Changyin's soup. This laxative does not work immediately and does not work until twelve hours after taking it. Once the drug has taken effect, he will go to the toilet without stopping for five hours. I can only stay in the toilet all the time, and I can't leave it at all.

Fang Li calculated the time, now it should be the time for the medicine to take effect. However, Zheng Changyin doesn't seem to have anything going on at all? Fang Li looked at Teacher Zhang beside Zheng Changyin again. Mr. Zhang's spirit is also very good, and there is nothing wrong at all.

At that time, in order to ensure that Zheng Changyin took laxatives, Fang Li put laxatives in both soups. Teacher Zhang and Zheng Changyin are in the same room, so they should both be subservient. Could it be that the effect of the medicine has expired and has not worked? Fang Li was puzzled.

At this moment, Zheng Changyin suddenly looked at Fang Li, winked at her, and smiled evilly. Fang Li's heart chuckled, and she quickly turned her face away. Fang Li's heart was flustered, how could she feel as if Zheng Changyin had found out? No way, there was no one in the kitchen at the time, how could she find out?

The staff of the organizers came in, stepped onto the podium, and began to talk about the finals. At this time, Fang Li felt a burst of colic in her stomach, which was very uncomfortable, and she couldn't help but cover her stomach with her hands.

"I'm going to go to the bathroom." Suddenly, the teacher beside Fang Li dropped a word, covered his stomach with his hands and left in a hurry.

Fang Li's face turned white all of a sudden. This teacher is in the same room as her! Could it be that she mistakenly gave a laxative to the lunch box in her room yesterday?

There was another cramp in her stomach, and the pain made Fang Li's forehead sweat. What the staff said on the podium, Fang Li couldn't listen to it at all. turned his face to look at Zheng Changyin and Teacher Zhang again, and saw that they were still fine, and there was nothing unusual. Fang Li's mood suddenly fell to the bottom, she obviously checked the room number at that time, how could she be mistaken?

Just when Fang Li was puzzled, Zheng Changyin turned his face and smiled at her proudly, and stuck out his tongue. Fang Li instantly gasped and immediately understood. It's Zheng Changyin, it's Zheng Changyin who swapped the two lunch boxes!

Before Fang Li could figure out how Zheng Changyin changed the lunch box, she couldn't hold it anymore, and said to the principal on the side: "Principal, my stomach hurts and I want to go to the toilet." ”

"The finals are about to begin, bear with me." The principal frowned and did not agree with Fang Li to go to the toilet.

"I really can't help it!" Fang Li, who has always been very obedient to the principal, has no way to follow this time. After saying that, he left in a hurry.

"Fang Li......" No matter how the principal shouted, Fang Li didn't look back.

Those present began to whisper. The finals started immediately, why did Fang Li leave?

"Classmate Fang went to the toilet, and she will be back soon." The principal of Changkang hurriedly explained to the staff.

"We're in five minutes and we're in the final, and if she doesn't come back, she's giving up." The staff replied solemnly.

"I'll be driven back, I will." After saying that, the principal of Changkang also left and walked in the direction of the toilet. In any case, she had to bring Fang Li back within 5 minutes.

Zheng Changyin finally couldn't help it and laughed.

"Changyin, what are you laughing at?" Teacher Zhang asked curiously.

"Nothing, nothing." Zheng Changyin hurriedly waved his hand and put away his smile.

Of course, Mr. Zhang would not have known what happened yesterday evening.

Zheng Changyin was stared at by Teacher Zhang, and he couldn't get out of the guest house, so he could only move in the guest house. At that time, she was wandering in the corridor when she saw Fang Li sneaking into the kitchen.

Fang Li, why did she go into the kitchen? Is it to go in and steal something to eat? Zheng Changyin was curious, and immediately jumped into the space, and followed into the kitchen to look.

Zheng Changyin thought that Fang Li was stealing something to eat at first, and he really underestimated her. I saw that Fang Li looked at the row of lunch boxes, as if she was looking for something. Finally, he stopped in front of the lunch box with Zheng Changyin's room number attached.

Zheng Changyin's heart burned with a bad premonition, and she stood beside Fang Li, staring at her without blinking. How could Fang Li have thought that in the dark, there were a pair of bright eyes staring at her?

Fang Li looked around to see that there was no one, so she took out a packet of medicinal powder from her pocket and poured it into the lunch box.

Zheng Changyin was furious! She almost wanted to rush out of the space and catch Fang Li right. However, she still held it back and did not expose Fang Li on the spot. A thought ignited in Zheng Changyin's mind: she wants to treat others the way she does!

So, Zheng Changyin stared at Fang Li silently, and it wasn't until Fang Li completed a series of actions and left the kitchen that Zheng Changyin jumped out of the space.

Zheng Changyin quickly swapped the lunch boxes in his room and Fang Li's room.

"Fang Li, Fang Li, are you okay?" Outside the toilet door, Changkang's principal kept patting on the toilet door.

"Fang Li, hurry up, the game is about to start." The principal was anxious. Why do you go to the toilet when it's time for the game? Maybe I'm in too much of a hurry and haven't found out anything wrong with it. At this time, Fang Li was not the only one in the toilet, but also a teacher who shared the room with Fang Li.

"Fang Li, hurry up, you come out quickly!" The principal almost broke the toilet door.

Suddenly, there was a squeak, and the toilet door was really opened from the inside. A strange smell came, and the principal couldn't help but reach out and cover his nose.
