After Duan Feihan returned from working overtime in the company, he asked the Duan family's housekeeper, and then strode towards Duan Xingye's bedroom.

Duan Xingye didn't lock it, because he was too serious about the question, and he didn't even hear Duan Feihan knocking on the door.

Duan Feihan walked in, seeing Duan Xingye scratching his ears and cheeks at a math fill-in-the-blank question, he said lightly: "Negative root number three." ”

Duan Xingye was startled and looked at the handsome man beside him: "Fourth uncle, why are you here?" I'll do the question! Negative root number three? Oh yes, I just miscalculated! Fourth uncle, you can do it, it's been several years since you graduated from graduate school, and you still do college entrance examination questions? ”

If it were someone else, I would have forgotten about it.

His fourth uncle didn't even use scratch paper, and directly told him the answer by mental arithmetic, hey, this is the gap, the heart is congested.

Duan Xingye was a little strange why Duan Feihan came to his bedroom.

Duan Feihan took out his mobile phone, which had been playing and was slightly hot, and threw it in front of Duan Xingye: "It's better to listen to the explanation more." ”

Duan Xingye was a little puzzled, how could his fourth uncle deliberately find an online live broadcast of teaching for him? When he saw the hands, the white paper and the black gel pen, he had an epiphany.

Isn't this the one that the fourth uncle watched yesterday?!

Duan Xingye looked at the hands in the camera for a while, and then looked at Duan Feihan's cold and handsome face, and suddenly said, "Fourth uncle, is this Weiwei?" ”

Duan Feihan narrowed his eyes, "How do you know?" Do you stare at her hand every day? ”

The little girl didn't know what voice change method was used, and he didn't hear it until he saw the hands and Bai Chuwei's unconscious movements, and he didn't officially confirm it.

Duan Xingye almost jumped up: "How dare I stare at Big Weiwei's hand every day?" Fourth Uncle...... You're staring at someone's hand, right? How else would you recognize it? ”

Duan Fei asked without changing his face: "Salted fish video app is my industry, do you think I can't see the background information?" ”

Bai Chuwei invaded the background of the salted fish video app and didn't fill in the ID card information at all! Her backstage is blank.

Duan Xingye: "...... Oh, that's right. ”

seems to be the truth, anyway, he can't talk about the fourth uncle!

Duan Xingye's eyes shifted to the mobile phone video, although he couldn't see the anchor, but the explanation was everywhere!

The quadratic function that happened to be talked about, there was one thing that Duan Xingye had not figured out, and suddenly he suddenly realized something.

Seeing that he was fascinated, Duan Feihan took his mobile phone and lightly threw down a sentence: "Use your mobile phone to watch it yourself, I'll go back to the room first." ”

Duan Feihan walked out towards Duan Xingye's bedroom door with his mobile phone, and just stepped out with one foot, his nephew's hearty voice came from behind him: "Fourth uncle, it's impossible for you to catch up with Wei Wei like this." ”

Duan Feihan's footsteps paused.

Duan Xingye leisurely picked up the coffee cup on the table and took a sip to refresh himself.

"Fourth uncle, I advised you not to worry about the little fairy, be careful of ending up with the same fate as the third uncle, if you don't listen, forget it. And as you are now, it is impossible for you to catch up. ”

Duan Feihan's eyes were already dark, and there seemed to be a whirlpool lingering in them......

Duan Xingye saw that the signs were wrong, and he didn't dare to drink the coffee, and his desire to survive made him speak very quickly: "Fourth uncle, didn't you see that Wei Wei has been talking for so long?" Isn't she thirsty? What's the use of you giving her a gift just online? There are so many people who give her gifts online, who do you think she has taken care of? Have you ever said thank you to anyone? ”
