"This view is that humans have developed a kinship monitoring mechanism in order to avoid inbreeding during evolution."

Biology make-up lessons during the holidays - of course Lou Wuchen would not admit that this was an evil make-up lesson. In his words, it was a layered advancement lesson that he voluntarily participated in in order to adjust the progress difference - when he went to school, Lou Wuchen followed the students again

Our questions opened up extracurricular expansion topics: "Two children who grew up together in their early years usually do not have sexual attraction to each other as adults. Especially the growth environment for the first six years after birth, during which time the children who lived together will not be sexually attracted to each other.

Between the two, the chances of sexual attraction will be greatly reduced..."

"Oh!" Zangmitsu clapped his hands as if he suddenly understood, "No wonder the childhood sweethearts in the book always can't win against Tianshuang!"

"!" Xiang Yu pinched Zang Chongzhi calmly and said: "Stop pretending to be weird! Listen to the class!"

Zangmitsu grimaced in pain and dared not speak any more, but the topic he started had already aroused extensive discussion among his classmates. Apparently there were many novel lovers in Library No. 11.

"But I think childhood sweethearts are pretty good? I just like them."

"That's because as a reader, you think they all came from heaven, right?"

Lou Wuchen was not angry about this, he just leaned against the podium leisurely with a water glass, and waited until the students who were running away from the topic were almost finished discussing, then he clapped his hands and shouted: "Okay everyone, let's continue -

—”

"By the way, teacher!" Zuo Li stood up as if she suddenly remembered something, "If there is such a mechanism that makes children who grow up together unattractive to each other, does that mean that under the original circumstances..."

Lou Wuchen was stunned for a moment, then gave Zuo Lixige a nod of praise and motioned for her to sit down: "Xiao Li, your idea is great. There is indeed a view that there is something called "Xiao Li" in adults who are very closely related by blood.

hereditary sexual attraction

Phenomenon. They have not lived together for a long time, or have never met before. Once they reach sexual maturity and meet for the first time, the same genetic genes will prompt one or both parties to have instinctive sexual attraction. This kind of sexual attraction

The attraction is stronger than the attraction to people who are not related by blood, sometimes to the point of being uncontrollable..."

Suddenly, Lou Wuchen's heart skipped a beat, and a beautiful shadow emerged from his heart, merging with the handsome figure walking outside the window.

"...It's almost noon, students, let's go have lunch first." Lou Wuchen looked at the time and said to the students, "Everyone can discuss in groups. We will come back in the afternoon to continue this problem. get out of class is over!"

Lou Wuchen left the classroom and walked quickly to Youxue who was walking away. He looked at her and Mu Mijia beside her: "Sister, are you leaving?"

"Yes." Youxue turned around with her hands behind her back. She tossed her tied long hair back and opened a bright smiling face like a curtain. "I saw that you were still busy, so I didn't bother you. I was just here to begin with."

The person who took this child back has seen a lot of things in your school and city these days, so it’s almost time to go back.”

"Don't you want to stay for two more days?"

"No." Youxue smiled and shook her head, "I know you have informed Master, she should be arriving soon, right?"

"..." Lou Wuchen was silent for a while and then said, "Master Yaoguang, she has always cared about you."

"I know..." Youxue looked at the empty sky in the distance and sighed, "It's just that it's not the time for me to see her now..."

The two of them stared at the sky in silence for a while, and then Youxue laughed again, turned around and straightened Lou Wuchen's slightly messy hair on his forehead: "Don't make such a grimace, I'm not treating your

The abducted student will not come back, so it’s a good time to start school

When you come back, maybe there will be a big surprise for you? - Come to Mijia and say goodbye to your teacher Lou."

"Goodbye, Mr. Lou, happy summer vacation."

"...Well, happy summer vacation. See you at the beginning of school, Mijia." Lou Wuchen bent down and waved to Mu Mijia, and then suddenly asked Youxue, "Sister, where should I go if I want to find you?"

Youxue blinked, as if wondering why Lou Wuchen asked this question that obviously shouldn't be asked. However, Lou Wuchen did not give in, patted Mu Miya's head, and continued calmly: "Don't go directly

That’s okay, but I have to go on a home visit, so I have to be able to find a place, right?”

Youxue looked at Lou Wuchen's face seriously, and Lou Wuchen also looked back seriously. After a while, Youxue burst into laughter, took out a piece of thin silk and wrote something on it: "

Okay, okay...if something really happens, just go to this place and light a bonfire, and someone will come to lure you."

Youxue took Lou Wuchen's hand, gently peeled off his fingers and put the fine silk in, then closed his fingers one by one: "I'm leaving... Goodbye, Xiaolou."

Under the sky where the snow disappeared, Lou Wuchen stared blankly for a long time. When the lunch break was almost over, Lou Wuchen slowly turned around, only to see two figures flying at high speed from the other side.

"Wuchen!"

In a few breaths, Shuishui Yaoguang landed next to Lou Wuchen and looked at Lou Wuchen eagerly. Yun Hengguang on the side did not speak, but his expression was equally concerned.

"Where's Yuxue? She...is gone?"

"……Um."
