Stop pretending, I'm a security guard, a five-star general!

"Hahaha!"

Upon hearing this, everyone in the classroom burst into laughter.

It's impossible for two parents with type A blood to have a child with type B blood. Even someone who hasn't studied biology knows that this is impossible.

At that moment, two options appeared in front of Qin Yu.

[Option 1: Sincerely admit your mistake and promise to get a double-digit score next time. Reward: Hair starts growing on Cai Zhuang's bald head.]

Option 2: Find a counterexample to prove your judgment is correct, leaving Cai Zhuang speechless. Reward: Mastery of high school biology.

Seeing the two options in front of him, Qin Yu was speechless.

Whether Cai Zhuang's bald patch grows hair or not has nothing to do with him.

Hurry up and climb!

Thinking of this, Qin Yu also asked with a questioning look:

"Teacher Cai, how do you know that two parents with type A blood cannot have a child with type B blood?"

Cai Zhuang was almost amused by what he heard:

"Come on, if you can find me a child with type B blood whose parents are both type A blood, I'll kowtow to you and call you 'Dad' right now!"

"Um, Ms. Cai, there's one in our class."

"Huh?" Cai Zhuang was taken aback.

Qin Yu pointed to a short, chubby boy sitting in the back row of the classroom:

“Zhang Xiaopang in our class is one of them. He has type B blood, but his parents both have type A blood.”

Cai Zhuang: "???"

Everyone: "???"

Zhang Xiaopang: (⊙﹏⊙)

Zhang Xiaopang cried.

The kind that makes you cry loudly.

He was one of only two people in the entire grade, after Qin Yu, to answer this true/false question incorrectly.

He had always believed that two parents with type A blood could have a child with type B blood.

After all, he himself is the most direct proof.

But to his utter surprise, it turned out that two parents with type A blood could not possibly have a child with type B blood!

At that moment, Zhang Xiaopang instantly realized something.

One of his parents was definitely not his biological parent.

Zhang Xiaopang's worldview collapsed instantly at that moment.

Cai Zhuang was completely caught off guard and utterly dumbfounded.

He never expected that a simple true/false question would uncover such a shocking secret.

Um... I'm staying in Bengbu.

"Ding! Selection complete, reward received: Mastery of high school biology knowledge."

At this moment, Qin Yu, whose mind was flooded with countless biological knowledge, understood for the first time that two parents with type A blood could not have a child with type B blood...

Thinking of this, he couldn't help but look at Zhang Xiaopang behind him, his eyes filled with sympathy and guilt.

Little Fatty, I'm so sorry, bro. ┬＿┬

Zhang Xiaopang went home crying.

He wanted to go back and confront his parents, to find out who had betrayed whom.

Hearing that Zhang Xiaopang still hadn't figured out who had betrayed whom, Qin Yu shook his head helplessly.

All I can say is that this silly boy has managed to get by until now thanks in no small part to his intelligence, which is comparable to that of Zhuge Liang and Pang Tong.

The morning classes continued.

Qin Yu only needs to master Chinese now, and then he will be able to master all the other academic subjects.

Therefore, in the third period of Chinese class, Qin Yu also went crazy trying to trigger the options.

However, it just wouldn't trigger.

Then, naturally, Qin Yu was asked to leave the classroom by the angry Chinese teacher and stand in the corridor.

Qin Yu also looked helpless.

It seems that triggering options is also a matter of luck.

We should let things happen naturally; forcing our way in doesn't seem to be an option at the moment.

Bored, Qin Yu yawned and turned his gaze to the playground below, intending to examine the legs and improve his aesthetic sense.

At this moment, a class is having a physical education class on the playground.

The girls sat in small groups on the lawn, chatting with each other, while the boys played basketball.

Whenever the girls looked at them, the intensity of the boys' competition instantly escalated from a village-level contest to a world-class professional league contest, with each of them unleashing 120% of their strength!
