Zhou Qin, Feng Na and Cheng Cheng listened carefully and nodded one after another.

Li Yundong saw that there was a leftover rice plate next to him, took a chopstick, dipped the other end of the chopstick in water and wrote on the table: "so, review + no review = don't fail + fail, extract the common factor according to the mathematical method, so that we can get (1 + NO) review = (no + 1) fail, and then make an approximate score on both sides, so review = fail!"

With that, Li Yundong threw his chopsticks on the table: "see, this is the birth of truth!"

Zhou Qin chuckled, pursed his lips and said, "what a fallacy!"

Feng Na and Cheng Cheng do not have the awareness of Zhou Qin that they always maintain the demeanor of a young lady. They laugh without image. Feng Na laughs straight on the table and Cheng Cheng laughs back and forth.

Only Su Chan blinked and looked at this and that. She didn't understand what they were laughing at.

"Yundong, what are you laughing at?" Su Chan pulled Li Yundong's sleeve.

Li Yundong said with a smile, "you don't understand the things in learning?"

Su Chan's mouth tilted high: "I don't understand. I don't think it's funny at all!"

Cao Kefei also said with a smile: "well, well, go to fetch rice first. I'm hungry!"

Several people got up and went to eat. All the people were handsome and beautiful. The master couldn't help but give enough food, which caused a serious protest from the students lining up behind.

Returning to her seat, Feng Na smiled and said, "Li Yundong, if you just spread this to the forum, I'm afraid half of the students will fail this year. You don't know how many people in this school are your fans, so you should pay attention to your words and deeds and play an exemplary leading role!"

Li Yundong said with a smile: "exemplary leadership? OK, I'll sing a song. You send it to the forum at night and tell them everyone to sing twice every morning and evening to ensure that they don't fail!"

Zhou Qin couldn't help laughing and said, "what's wrong with you?"

Li Yundong looked wronged: "why do you say that about me? What a pure and honest young man I am! You see, I also write words to encourage my students to pass the exam. How noble and selfless I am. You should issue me a red flag on behalf of the party and the people!"

Feng Na said with a smile, "don't you have a red flag?"

Li Yundong was stunned and slapped: "yes, then give me a red flag!"

Cao Kefei, who had been smiling and listening to them, couldn't help laughing: "greedy snake swallows elephant!"

Cheng Cheng smiled and knocked on the plate in front of Li Yundong with his chopsticks. He urged, "don't say these useless things. Hurry up and sing a song. It's right here. I haven't heard you sing yet!"

Li Yundong suddenly pinched: "really want to sing? Cough, I'm a little rough. Can you stand it?"

This is very ambiguous. Zhou Qin couldn't help but blush, spat secretly, turned his face, and for a moment he couldn't help thinking of the absurd scene in the dreamland, and couldn't help heating up.
