The divorce comeback system arrived right after I was born.

That bottle of imported milk had a rather strong aftereffect.

Perhaps it was because he had just finished intense military training and his body was in a state of extreme fatigue and retaliatory relaxation, coupled with the intake of high sugar, that Chen Zhi's eyelids started to droop as soon as the bell rang for the first class.

Chen Zhi spread the books on the table, creating a makeshift defense, buried his head in his arms, and his breathing instantly became long and even.

On the podium, Zhang Guoping, the math teacher of Class 3, Grade 7, was organizing his lesson plan with a gloomy face.

Zhang Guoping is a formidable character. In his forties, he already has a receding hairline, commonly known as "Mediterranean hairline."

The classroom was quiet, with most students sitting upright, barely daring to breathe. After all, it was the beginning of the semester, and no one wanted to provoke this tyrant.

Apart from Chen Zhi.

Li Jiahao, sitting in the front row, was full of energy.

His current mental state is very twisted. The bottle of imported milk that Chen Zhi drank has fueled his resentment. He glanced back and saw that Chen Zhi had already slumped down, his shoulders even rising and falling slightly with his breathing.

God help me too.

A sinister smile curled at the corner of Li Jiahao's mouth.

You enjoyed drinking my milk just now, didn't you? And you're acting all nonchalant in front of your goddess.

I'm going to make you vomit everything you've drunk right now.

Zhang Guoping had just turned around and written the words "Introduction to Geometry in Junior High School" on the blackboard, preparing to begin his lecture.

"Reporting, teacher!"

A sudden and loud shout broke the silence of the classroom.

Zhang Guoping paused, his brows furrowing instantly. He turned around, his gaze sharp: "What is it?"

Li Jiahao jumped to his feet, his face radiating righteous indignation, and pointed straight to the back corner: "Teacher, Chen Zhi is sleeping in class! And he's snoring, seriously affecting my concentration!"

All the students in the class turned their heads in unison.

There was no snoring sound.

Chen Zhi was just sleeping soundly, his breathing was a little heavier. But in this quiet classroom, when Li Jiahao amplified it, the nature of the situation changed.

Zhang Guoping hates nothing more than students sleeping in his class. It's a sign of disrespect for his teaching authority.

"Chen Zhi!"

Zhang Guoping let out a loud shout and slammed the triangle ruler in his hand heavily on the lectern, sending chalk dust flying everywhere with a loud "crack".

In the back corner, the figure that had been lying down stirred.

Chen Zhi groggily raised his head, his face still bearing the red marks from the creases on his sleeve. He rubbed his sleepy eyes and looked around blankly.

Who am I? Where am I? Why are so many people looking at me?

"Stand up!" Zhang Guoping pointed at him, spitting as he spoke. "You dare to sleep through a regular class on the first day of school? Do you think this is a hotel?"

Chen Zhi slowly stood up, still a little dazed.

Pei Ningxue, sitting upright beside her, stared straight ahead, as if everything happening around her had nothing to do with her. She simply moved her textbook slightly to the side, as if afraid of being affected.

"Teacher, I have low blood sugar," Chen Zhi said casually, making up an excuse as he yawned.

"Low blood sugar?" Li Jiahao sneered from the front, interjecting sarcastically, "You just drank such a big bottle of milk, how could you have low blood sugar? I think you're just being silly."

A few suppressed laughs rang out in the classroom.

Zhang Guoping's face darkened further. He pushed up his thick glasses, which were as thick as the bottom of a beer bottle, and turned around to scribble a problem on the blackboard.

He originally planned to explain the basic concepts, but he got angry and pulled out a challenging problem from his head.

This is a geometry proof problem with a complex diagram and hidden auxiliary lines, which is clearly beyond the knowledge range of first-year junior high students. Even second-year junior high students would have to avoid it.

"Since you have so much energy, you should be able to solve this problem, right?" Zhang Guoping threw the chalk on the lectern, pointed to the blackboard, and said, "Come up and do it. If you can't, you'll be standing in the hallway for the entire class period with your book!"

Li Jiahao almost burst out laughing.

That problem was terrifying to even look at; it involved nested triangles and required proving the proportions of line segments. It was clearly not something you should be learning at this stage.

Chen Zhi is doomed now.

Being publicly humiliated and kicked out of the classroom—that's what happens when you offend me, Li Jiahao!

The whole class looked at Chen Zhi with pity. Lin Wanwan was so anxious that her face turned pale. She wanted to raise her hand to plead for Chen Zhi, but Zhang Guoping glared at her and stopped her.

Chen Zhi sighed.

He really didn't want to move.

I just woke up, my mind is still foggy, and my legs are weak. But judging from the situation, I have no choice but to do it.

He slowly left his seat, and as he passed by Li Jiahao, he could clearly feel the gloating look in the other man's eyes.

Chen Zhi walked up to the podium and picked up a piece of chalk.

He looked up at the question on the blackboard.

The previously cloudy eyes cleared up the moment they touched the lines and letters.

Although he didn't do very well in his previous life, he was still a science major and could still solve junior high school problems.

You don't even need to think.

Three solutions instantly came to mind.

Chen Zhi weighed the chalk in his hand, turned his head to look at Li Jiahao, who was still waiting to see him make a fool of himself, and the corners of his mouth turned up slightly.

Since you want to play, then I'll play big with you.

"clatter."

The chalk hit the blackboard with a crisp sound.

Immediately following was a series of rapid "tatatatatatata" sounds.

Chen Zhi's hands moved extremely fast, the chalk flying across the blackboard, leaving neat and elegant white characters.

The first solution: the conventional auxiliary line method.

Draw a line parallel to point D that intersects at point E...

Because triangle ABC is similar to triangle ADE...

and so……

The first solution was written in less than a minute.

Zhang Guoping had been standing to the side with his arms crossed, ready to berate Chen Zhi if he couldn't come up with anything coherent. But when he saw the auxiliary line, his expression changed.

This kid's got some skills?

However, Chen Zhi did not stop writing.

He drew a dividing line next to the first solution and then wrote "Solution Two".

The whole class was stunned.

Is there a second solution?

This time, Chen Zhi used the area method. It didn't require complicated auxiliary lines; he directly used the triangle area formula for derivation, making the process simpler and the logic more rigorous than the first method.

The classroom was eerily quiet, with only the echoing sound of chalk hitting the blackboard.

The students who were originally prepared to watch the spectacle were now all gaping in astonishment. Although they couldn't understand what was happening, they were deeply shocked.

Is this Chen Zhi, who was sleeping just now?

Li Jiahao's smile froze, as if someone had pressed the pause button. He stared intently at the blackboard, trying to find Chen Zhi's mistake, but he realized he couldn't even understand the first step.

"Da da da..."

The sound continued.

Chen Zhi nimbly turned his wrist and wrote down "Solution Three".

This time, he directly constructed a Cartesian coordinate system.

Let the coordinates of point A be (0, a), and the coordinates of point B be (b, 0)...

By utilizing knowledge of analytic geometry, complex geometric proofs are transformed into simple algebraic operations. This is a concept typically introduced in the first year of high school, but Chen Zhi applies it with effortless grace, delivering a revolutionary breakthrough.

Zhang Guoping's glasses slowly slid down to the tip of his nose, but he forgot to push them up.

He stared in disbelief at the three completely different problem-solving processes on the blackboard, especially the last one, which was definitely not something an ordinary first-year junior high student could possess.

"clatter."

With the last stroke, the chalk stub was used up.

Chen Zhi casually brushed off the remaining chalk dust, turned around, and precisely tossed the piece of chalk back into the chalk box.

This set of movements was incredibly graceful.

He didn't look at the dumbfounded Zhang Guoping, but instead turned his gaze to Li Jiahao, who was sitting in the fourth row with a pale face.

"teacher."

Chen Zhi's voice was lazy and nonchalant, "This question is actually quite simple, just an introductory question. But I saw Li Jiahao's expression was so varied just now, it seems like he has a problem with me."

He paused, then pointed to the third solution on the blackboard: "Especially this third one, which uses analytic geometry from the first year of high school. I'm worried that Li Jiahao might not understand it. Do you need me to explain it to him separately? After all, classmates should help each other."

boom--

These words were like a resounding slap across Li Jiahao's face.

Murder and kill!

The eyes of the whole class were once again focused on Li Jiahao, but this time, instead of echoing him, they were filled with mockery and ridicule.

You were jumping around so enthusiastically just now, are you dumbfounded now?

Not only did they succeed, they used three different methods! They even worried you wouldn't understand!

Li Jiahao's face instantly turned a deep purplish-red, filled with shame and indignation. He opened his mouth, wanting to retort, but found himself utterly speechless. Faced with absolute power, any words seemed pale and powerless.

Zhang Guoping finally came to his senses.

His gaze towards Chen Zhi completely changed, from previous disgust to the ecstatic joy of finding a treasure.

"Ahem." Zhang Guoping cleared his throat, trying to maintain his teacher's authority. "That... is a good solution. The thought process is very clear. It seems that Chen Zhi put in a lot of effort over the summer."

He glared at Li Jiahao: "Some students, if you don't understand, don't cause trouble! Pay attention in class!"

Li Jiahao buried his head in his chest, wishing he could disappear into a crack in the ground.

"Alright, go down now. Pay attention in class from now on, don't sleep too soundly." Zhang Guoping's tone was noticeably gentler.

Chen Zhi nodded and walked back to his seat with an air of indifference.

As he passed by Lin Wanwan, the little girl gave him a thumbs up.

Chen Zhi returned to his seat and let out a long sigh of relief.

We managed to fool them at least once.

Just as he was about to lie down again to catch up on his sleep, a neatly folded piece of draft paper was silently pushed over from the side.

Chen Zhi was taken aback and turned to look.

Pei Ningxue maintained her aloof posture, taking notes, not even glancing at him out of the corner of her eye.

Chen Zhi curiously unfolded the draft paper.

There were only two characters on it, written in neat and powerful handwriting, exuding an air of arrogance:

【sharp.】

Chen Zhi raised an eyebrow.

This is the evaluation given by Pei Ningxue, who is known as the "Iceberg Miss".

He picked up a pen, drew a simple smiley face after the word "amazing," and then pushed the paper back.

Pei Ningxue paused slightly when she saw the note being pushed back. She didn't look at the smiling face, but quickly tucked the note into her book, a faint smile flashing across her lips once more.

The bell rang, signaling the end of get out of class.

No sooner had Zhang Guoping stepped out of the classroom than the classroom erupted in chaos.

"Holy crap! Squad leader, you've been hiding your true abilities!"

"When did you start self-studying until high school level?!"

Several boys gathered around, showing great admiration for Chen Zhi.

Chen Zhi waved his hand modestly, "Keep it low-key, keep it low-key. It's just that the question was too easy, anyone could do it."

Upon hearing this, Li Jiahao, who was not far away, almost spat out a mouthful of blood.

Just have a hand?

Are you calling me handless or brainless?

"Chen Zhi".

A cool, clear voice rang in my ears.

The boys standing nearby immediately quieted down and made way for them.

Pei Ningxue packed her schoolbag, stood up, and looked down at Chen Zhi. She was backlit, with a few strands of hair hanging down beside her ears, and her beauty was breathtaking.

"What's wrong, deskmate? Are you impressed by my talent?" Chen Zhi asked with a grin.

Pei Ningxue ignored his banter and instead pointed to the third solution that hadn't been erased from the blackboard.

"Wouldn't it be simpler to set the origin of that coordinate system at point D?"

Chen Zhi was stunned for a moment, then a hint of surprise flashed in his eyes.

This girl not only understood it, but did she really study it all the way up to high school level?

"Indeed." Chen Zhi put away his joking expression and nodded. "Setting it at point D can save two equations, but I deliberately chose a complicated one just to show off."

Pei Ningxue watched him frankly admit to "showing off," and a barely perceptible smile flickered in her eyes.

"boring."

She left with just two words, picked up her backpack, and turned to leave.
