My family has been wielding knives for generations, but now it's my turn to wield a pen!

"Um?"

Jiang Xiaobai's face stiffened immediately upon hearing Zhang Xinnian's words.

He slowly turned his head and looked at Zhang Xinnian.

This guy...

You really know how to bring up a sore spot!

What do you mean, "There are people all up there"?

How could he explain himself after saying that?

After thinking for a moment, Jiang Xiaobai looked at Zhang Xinnian seriously and said, "Xinnian, your vision is too narrow. You only look at pictures?"

"Didn't you see? Those little figures have meridian diagrams on them!"

"Oh, really?!"

After hearing this, Zhang Xinnian leaned closer for a careful look, and after a moment, his eyes lit up: "Huh? It really is!"

"As expected of the Crown Prince!"

As they spoke, Zhang Xinnian turned his gaze back to Jiang Xiaobai, his face full of admiration: "That's incredibly detailed!"

"I didn't even see it if you hadn't pointed it out!"

"..."

Jiang Xiaobai's lips twitched violently.

This guy, if he can't talk, he can just stay silent.

What do you mean he only cares about details?!

Is that what he meant?

Tang Ningshuang blushed even more as she listened, and couldn't help but turn her head and glare at Jiang Xiaobai.

man!!

"Young Master Jiang, this is a unique manual on dual cultivation."

Chang Ying was embarrassed for a moment, then said, "If one can find a martial arts master to guide them and practice their internal energy according to their methods, it can indeed help beginners get started faster."

"only……"

Chang Ying paused, then looked at Jiang Xiaobai and continued, "Young Master Jiang's cultivation level is quite profound. Logically speaking, this internal energy cultivation method shouldn't be very suitable for you."

That's right, Ruo Jiang Xiaobai is indeed a master who has entered the ninth realm.

Then this book would be meaningless to him.

After all, this method is more geared towards introducing people to the basics.

Instead of helping experts reach even greater heights.

"this……"

Jiang Xiaobai was momentarily embarrassed, but before he could speak, Zhang Xinnian suddenly spoke up from the side.

"Steward Chang, may I just watch, even if my young master doesn't practice?"

"..."

Jiang Xiaobai almost kicked him.

Chang Ying was also taken aback by Zhang Xinnian's words.

After a moment, Chang Ying nodded with a strange expression: "This, of course... is possible."

Jiang Xiaobai gave Zhang Xinnian a wry smile and glared at him irritably.

Zhang Xinnian shrank back, not daring to say anything more.

Jiang Xiaobai was too lazy to explain any further. He immediately put the book "Dragon and Phoenix Harmony Technique" into his pocket, cleared his throat, and changed the subject, saying, "Now that we've made our choice, let's go downstairs."

Chang Ying nodded and led the group out of the martial arts library.

After the iron gate closed again, the group walked towards the direction of the dormitory.

Before they even got close, a middle-aged man hurriedly came to greet them.

Upon seeing Chang Ying, the man immediately breathed a sigh of relief: "Manager Chang, so you're here!"

"What's wrong?"

Chang Ying frowned, a look of doubt on her face.

"Oh……"

The middle-aged man quickly said, "The head steward wants you to go to the Imperial Academy again."

"Going again?"

Chang Ying visibly felt a headache coming on when she heard about the Imperial Academy.

"yes!"

The middle-aged man nodded, his expression serious. "The head steward said that this time, no matter the cost, you must take this!"

"That thing is too important to our Tianji Workshop."

"this……"

After listening, Chang Ying remained silent for a moment, and finally sighed softly: "Okay, I understand."

The middle-aged man then cupped his hands in greeting, turned around, and hurriedly left.

"Manager Chang, what's wrong?"

Jiang Xiaobai, standing to the side, listened with some curiosity: "What are you going to the Imperial College for?"

"Young Master Jiang, you are unaware of this!"

Chang Ying glanced at Jiang Xiaobai, hesitated for a moment, and then explained, "The Imperial Academy has recently published a set of mathematical methods."

"Methods of calculation?"

Jiang Xiaobai raised an eyebrow slightly.

"good."

Chang Ying nodded and said, "I've heard that this method is extremely ingenious. It will be of great use to our Tianji Workshop in deducing mechanisms and disassembling artifacts."

"Especially for some complex mechanisms, if this method can be used to calculate in advance, many detours can be avoided."

"Therefore, Tianji Workshop is willing to pay a great price to learn this method."

"Um?"

As Chang Ying finished speaking, Zhang Xinnian exclaimed in surprise and subconsciously looked at Jiang Xiaobai.

Yes, wasn't that method of calculation the one that my own son taught Master Song at the Imperial Academy that day?

At that time, the Crown Prince casually wrote down a few formulas, which greatly surprised the Imperial Academy official, Song.

I never expected that in just a few days, even Tianji Workshop would have its eyes on them.

Jiang Xiaobai naturally thought of this as well, and his expression became somewhat strange.

This stuff spreads pretty fast!

But thinking about it carefully, it makes sense, since Tianji Workshop is a manufacturer of mechanical devices.

The more precise something is, the more it relies on calculations.

His modern mathematical methods, for this world, are somewhat like a game-changer.

If placed in machinery or equipment, it would be extremely suitable.

Jiang Xiaobai looked at Chang Ying and asked, "Why did they let you go over? Are you familiar with the people inside?"

"Um."

Chang Ying nodded gently: "I have some connection with that Master Song from the Imperial Academy."

"He would occasionally ask me to make some of his math teaching aids."

"Given this relationship, why wouldn't he tell you?"

Jiang Xiaobai said with some surprise.

"Yes, he said that he did not create this method. He would not dare to teach it without the approval of the person who created it."

At this point, Chang Ying gave a wry smile: "But when I asked him who that person was, he wouldn't tell me."

"The head steward has urged us several times, but... this time, we'll probably just be met with a cold shoulder again."

"hehe……"

Jiang Xiaobai burst out laughing upon hearing this.

This Master Song is quite proper.

They didn't take his things; they just handed them out casually.

That's a good point.

"What is Prince Jiang laughing at?"

Seeing Jiang Xiaobai smile, Chang Ying couldn't help but ask.

After speaking, she looked slightly displeased, thinking that Jiang Xiaobai was making fun of her.

"Oh, it's nothing!"

Jiang Xiaobai waved his hand, looked at Chang Ying, and slowly said, "Like this..."

"If you go to the Imperial Academy again, mention my name; it should be more effective than you!"

"What is the name of Prince Jiang?"

Chang Ying was taken aback and looked at Jiang Xiaobai, saying, "Could it be... that Young Master Jiang also knows Master Song inside?"

"Yes, we've met twice!"

Jiang Xiaobai nodded.

What he said was true; the first time was at the Imperial Academy, and the second time was in the imperial court.

Only these two times.

"Two-sided?"

Chang Ying smiled and said, "Hehe, that might not be very feasible. Master Song is quite stubborn. Even though I know him very well, he still refuses to ask!"

She didn't say what came next, but the meaning was already very clear.

Although Jiang Xiaobai is the heir of a marquis's family, Master Song doesn't care about such status.

"Trust me, it will definitely work!"

Jiang Xiaobai naturally understood Chang Ying's meaning, and a smile played on his lips as he said, "After you mention my name!"

"He will surely tell you who invented this method of calculation!!"
