After leaving White Horse Academy, Wei Yu went straight back to his residence.

He returned not for anything else, but to continue writing his mathematics textbook.

Damn it. In his previous life, when he was studying, Wei Yu had thought learning math was painful. But after coming here and reliving it, he realized—

Learning wasn’t painful.

Writing textbooks was the most painful thing!

If he could just copy existing materials, that would be fine, but the problem was—he couldn’t!

After all, some of the wordings were too modern. If he directly transplanted them, Wei Yu wasn’t even sure whether readers would be learning math or trying to figure out the meanings of the words.

In short, thinking of his own vacation, Wei Yu pulled an all-nighter writing textbooks again.

Previously, he had organized the math content up to the first year of high school. After a night of hard work, Wei Yu trimmed and trimmed the material, simplified and condensed it, and finally, before breakfast the next day, managed to finish compiling all the high school content.

“Hong Zhong, Bai Ban, your Highness is about to die of exhaustion here…”

Putting down the brush, Wei Yu collapsed onto the table, eyes closed, weakly calling out to his dear subordinates.

The door was pushed open, and Xiao Anzi came in with others.

One carried water, another wrung a towel, some supported him…

Wei Yu enjoyed a moment of massage service from Hong Zhong and Bai Ban.

Then, eyes still closed, he pointed at the finished textbooks on the table.

“Xiao Anzi, in a bit, take these booklets and give them to Fang Sheng. He knows who they’re for.”

Xiao Anzi glanced in the direction His Highness pointed to and obediently agreed.

After handling the business, Wei Yu quickly washed up and went to bed to catch up on sleep.

After he left, Hong Zhong and Bai Ban tidied up the desk.

Because these textbooks were self-compiled, Wei Yu had grouped the materials for grades one through six as primary school textbooks, and the junior and senior high school materials as secondary school textbooks.

As for college materials—forget it, too much. Wei Yu planned to deal with that after he returned from Jiaozhou.

After finishing the primary and secondary school textbooks, Wei Yu had neatly separated them: primary school materials to the left of the desk, secondary school materials to the right.

What he had pointed out for Xiao Anzi to take earlier were all primary school textbooks.

However, when Hong Zhong and Bai Ban were cleaning the desk—because of all the clutter—without anyone noticing, a secondary school booklet accidentally got mixed in with the primary school materials.

Then, Xiao Anzi delivered that stack of primary school textbooks to Fang Sheng.

Regarding the matter of recruiting Dean Zhang as the mathematics teacher, Wei Yu thought at least he’d have to wait until the man finished reading all the textbooks before anything happened.

But unexpectedly, the morning after delivering the textbooks, the man came on his own!

“What! He’s already here?”

Hearing Bai Ban’s report, Wei Yu froze.

He was just about to go into the palace to report to his father—how had Teacher Zhang shown up already? He read that fast? Did he pull an all-nighter too?

Anyway, since the math teacher had come to the door, it would be too rude not to meet him. So Wei Yu quickly got ready and went to the front hall.

However, when he saw Zhang Qingsheng again, he was startled by the man’s appearance.

His clothes were disheveled, his hair bun was loose, his expression was wild. When he saw Wei Yu, he rushed over in a flash. He was so close that Wei Yu could see the bloodshot veins in Zhang Qingsheng’s eyes.

“This was all written by you?!”

The familiar booklet was thrust right under Wei Yu’s nose.

Too close to see clearly, Wei Yu leaned back a bit and looked carefully.

Huh?!

Why the hell was it secondary school material? Didn’t he tell Xiao Anzi to take primary school textbooks?!

“Uh, well… does sir have a question?”

When facing an awkward situation, the best tactic was to answer with another question.

Facing this math fanatic—who looked like he had just found a priceless treasure—Wei Yu really didn’t want to admit anything.

Because admitting it would be very troublesome.

He didn’t want to waste his vacation discussing math. Wasn’t a vacation nice enough?

Zhang Qingsheng stared tightly at Wei Yu, a wild smile on his face, the red veins in his eyes showed he had a sleepless night.

“I knew it! Your talent in mathematics is astonishing! To have compiled these into a full booklet, and explained everything clearly—these principles, I have never heard of or seen anything like them in my life! A once-in-a-century genius! I am ashamed to be compared to you!”

Zhang Qingsheng held up the booklet, staring fiercely at Wei Yu. His hands trembled slightly with excitement, filled with both admiration and expectation.

“You’re mistaken, sir!”

Wei Yu smiled, blinking quickly, “I’m no genius. Since sir has come personally, you must know my identity. With my status, would I ever lack access to great scholars? This booklet is part of my private collection, written by someone else, truly.”

Zhang Qingsheng stared deeply at him, then flipped a page of the booklet, pointed at the fresh ink and brand-new handwriting, and said in an absolutely certain tone:

“This was clearly written just in the past two days!”

Wei Yu: …

Xiao Anzi had betrayed him!

“Well, that still doesn’t prove I wrote it.”

Wei Yu struggled on, “Although the writing is fresh, sir, you can’t deny that someone like me—a prince—could easily hire people who can write and know math to do it! So sir, you really have the wrong person.”

Zhang Qingsheng gave him a meaningful smile, “Alright, alright, if Your Highness says so.”

That left Wei Yu speechless.

It was perfunctory.

Teacher Zhang’s attitude was very perfunctory! It was obvious he had decided that Wei Yu had written it!

And in fact—

Zhang Qingsheng truly believed Wei Yu was the author.

After all, how could there be such coincidences in the world?

A young man highly skilled in math, claiming to have a personal collection, then immediately delivering a freshly written booklet? Who would believe it wasn’t his own work?

Not to mention, this young man’s identity was not ordinary either.

Looking at the young prince before him, Zhang Qingsheng silently sighed.

This was their Great Wei’s Wise King.

A prince on the surface, yet secretly passionate about mathematics—if this got out, it might cause ridicule among the world’s people.

After all, in the public’s eyes, only things sanctioned by the imperial examination system were considered proper studies.

Mathematics?

Just a minor, worthless subject.

Even though those who studied it knew its importance, that couldn’t change the fact that few people understood it!

No wonder the Wise King refused to admit it…

In his heart, Zhang Qingsheng had firmly decided that Wei Yu had written the booklet. Thus, no matter what Wei Yu said, he only responded with a “yes, yes, whatever you say, but I don’t believe you” attitude—making Wei Yu feel that even he was being overly petty.

So was it hard to just admit it?

Very hard.

When Zhang Qingsheng kept pestering him with questions about the contents of the booklet, Wei Yu became even more certain.

Damn it, he had already denied it three times, and this Zhang Qingsheng still wouldn’t let him go! If he admitted it, what would the future days be like?!

Finding a scholarly fanatic had this downside—

Too persistent.

Once he found something interesting, he wouldn’t stop until he figured it out.
