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

A strength value of over 11,000 is equivalent to the attack power of a five- or six-star Grand Martial Master!

What the hell!

Who else! ?

Qin Yu couldn't help but scream in his heart!

In this way, he only needs to teach two more ungrateful homeowners a lesson to completely complete his role as a security guard.

However, Qin Yu was not in a hurry.

He should be able to finish it by tomorrow at the latest.

After seeing Grandpa Wang off with a satisfied smile, Qin Yu returned to the guardhouse, leaned back in his armchair, and took out his phone and a tissue box.

I'm so happy today!

Differentiate it again!

……

The next day, Qin Yu walked into the classroom and saw Liu Damao looking furious.

"Da Mao? What's wrong? Who made you angry?"

Qin Yu asked with a curious expression.

"Don't even mention it. I don't know which bastard used my name to post a four-line poem on Douyin, basically saying that I was going to give him some real advice!"

"Damn it, why don't you buy a banana peel?! The school forum is full of people mocking me, calling me some kind of poet, my lifelong reputation is completely ruined!"

"I better not catch that bastard, or I'll skin him alive and pull out his tendons!"

Qin Yu: "..."

"Old Qin, why are you silent?"

"Um, I feel sorry for you... I'll treat you to KFC today."

"Waaaaah, my good brother! I love you!"

Soon, it was time for class.

Qin Yu glanced at the first class; it was biology.

Their high school curriculum consists of six subjects: mathematics, Chinese, history, chemistry, physics, and biology.

He had already mastered mathematics, history, chemistry, and physics by doing a series of multiple-choice questions.

Only Chinese and Biology are missing.

I need to quickly trigger two multiple-choice questions and catch up on these two subjects.

Qin Yu thought to himself.

The biology teacher was a bald old man named Cai Zhuang. He entered the classroom and glared angrily at Qin Yu.

"Qin Yu, come here right now!"

Qin Yu was taken aback upon hearing this, and obediently walked over.

Cai Zhuang slammed an exam paper on the table with a bang and angrily shouted:

"In my more than forty years of teaching, I have never seen such an extraordinary student as you!"

"Please teach me, how did you manage to get a zero on a test with twenty true/false questions and twenty multiple-choice questions?"

"Damn it, even if you just randomly picked all the answers, and got all the true/false questions right and all the multiple-choice questions A, you still couldn't possibly get a zero!"

Cai Zhuang was furious.

For this monthly exam, he specifically considered Qin Yu's terrible level and, in order to prevent him from getting a single-digit score, he increased the number of true/false and multiple-choice questions by half.

I thought that this kid's grades would break through to single digits, but I didn't expect that although he did break through to single digits, it was a reverse breakthrough. This time he got a big zero!

Upon hearing this, Qin Yu's expression suddenly turned serious, and he solemnly replied;

"Teacher Cai, you can question my learning ability, but you can't question my attitude towards learning!"

"I took this test very seriously. I didn't guess any of the true/false or multiple-choice questions. I thought about them carefully before choosing them."

Cai Zhuang was so angry upon hearing this that he almost vomited blood.

This time, he actually hoped that Qin Yu had just made all the random choices.

At least this means there's still hope for this kid.

And yet you're telling me you chose these after careful consideration?

To be able to avoid all the correct answers so accurately is something no normal human being could do.

Cai Zhuang clutched his chest, feeling his high blood pressure rising.

He pointed to one of the true/false questions and questioned it as if he were about to explode with anger:

"I won't talk about the other questions yet. Can you tell me why you answered with a checkmark for this question?"

"If both parents have type A blood, their child can have type B blood."

"Tell me, how can two parents with type A blood have a child with type B blood? What, did the child have a genetic mutation?"
