The immortal of the Tang Dynasty, but the game starts at Xuanwu Gate?

"A very peculiar... method, and these strange numbers." Li Shimin looked at the various numbers written down by Li Chengqian and couldn't help but start to think about whether these numbers could be implemented and what their practical value was.

In the end, Li Shimin concluded that it was indeed feasible to implement.

Because such numbers are so simple, not complicated or cumbersome at all.

Empress Zhangsun exclaimed in amazement, "He is truly a genius of the world. With Chengqian's current mathematical abilities, he is already more than capable of crushing all the scholars in the Imperial Academy's Mathematics Department."

"Erlang, tell me, just how many brilliant ideas does Mr. Chen still have in his head, and how many more amazing things can he come up with?"

Li Chengqian was very intelligent, and Chen Huai'an taught him very quickly.

Now, Li Chengqian has basically mastered quadratic equations.

Even a simple problem like the chicken-and-rabbit problem could take the great Confucian scholars of the Imperial Academy, or even the Chancellor, several days to solve.

Li Chengqian, however, only took less than a quarter of an hour.

How could they not be amazed?

"I'm afraid there are quite a few." Li Shimin's eyes flickered as he listened to Empress Zhangsun's words, his tone somewhat enigmatic.

"Chengqian, do you think what Huai'an taught you is useful?"

"Yes." Li Chengqian nodded. "At first, I was also puzzled and couldn't understand why you insisted on teaching me mathematics. But later, you said something to us."

"What did you say?"

"The master said that Confucianism, Legalism, integrity, and corruption are all empty concepts. From the beginning to the end of a dynasty, only money and grain are real."

"Everyone was calculating the costs from beginning to end!"

"Once the accounts become unclear, destruction is not far off."

Li Shimin wholeheartedly agreed with this.

A dynasty, from its beginning to its end, is indeed always settling accounts.

Especially after the Pei Ji incident and the chaos in the border accounts, Li Shimin attached great importance to this issue; otherwise, he would not have appointed Chen Huai'an, a man of strange conduct, as Minister of Revenue.

"Moreover..." Li Chengqian hesitated for a moment, "I think that the teacher may think that I am too young and cannot understand many things, so he taught me arithmetic first."

"For example, as you mentioned at the beginning, manufacturing capacity, economy, and manufacturing base determine the superstructure, as well as the two legendary techniques you spoke of."

"The teacher said that he would consider teaching us all of these subjects, but he chose mathematics first."

Manufacturing capacity, economy?

Empress Zhangsun fell into deep thought, somewhat unable to understand these two words.

However, Li Shimin did not focus his attention on this.

Rather, they were the two legendary techniques mentioned by Li Chengqian.

The two legendary techniques?

What kind of technique?

Li Shimin sat quietly, a possibility forming in his mind, and a storm of emotions surged in his eyes.

Could it be... the Dragon-Slaying Technique?

"......"

Two days later, inside the Duke of Anguo's residence.

Chen Sujin carried two large food boxes to the backyard martial arts hall.

At this moment, Chen Huai'an was shirtless, holding a homemade barbell weighing thirty kilograms in his hand. His muscles were taut, veins were slightly bulging, and sweat covered his entire body. The floor was covered in water stains.

Chen Sujin swallowed hard; this wasn't the first time she'd seen Chen Huai'an make this gesture.

She gripped the barbell, which she could barely lift with both hands, as if it were a sword, and swung it again and again like a knife.

Chen Huai'an told her that this person's name was Su Zhen.

Once, out of curiosity, Chen Sujin tried Suzhen with an ordinary long knife.

But she overestimated herself. Forget about Su Zhen, she couldn't even lift a knife once.

Not to mention someone like Chen Huai'an, who uses a 30-kilogram barbell as a knife to perform a ritual.

"Whoosh—"

With Chen Huai'an's perfect strike, the barbell slammed down with such precision that it was impossible to find a single flaw. The air whistled as the barbell crashed down!

"Fifty-one, fifty-two..."

Chen Huai'an remained tense, meticulously continuing to complete the Su Zhen procedure. Chen Sujin dared not make a sound, for fear of disturbing her younger brother.

On the eighty-eighth attempt, Chen Huai'an could no longer hold on. The barbell in his hand suddenly slipped, and Chen Huai'an staggered due to inertia.

"Xiao An".

Chen Sujin didn't care about anything else and quickly stepped forward to help Chen Huai'an. While taking out a handkerchief to wipe his sweat, she complained a little, "Why do you have to push yourself so hard? Last time you only did eighty, and today you've already done much more than last time."

"You're a civil official, you don't go out to fight, what's the use of training in these things?"

Chen Huai'an chuckled, panting, "Sis, I'm hungry."

"I brought food, wait for me." Upon hearing this, Chen Sujin lost her patience and quickly turned around to retrieve the food container she had just put down.

During this time, Chen Huai'an stared at his reddened palms in silence.

His guess was correct.

His power continues to grow.

Not only his strength, but also his speed, reaction time, and ability to withstand blows are continuously improving.

With a 30-kilogram barbell, he could only manage 80 repetitions last time, but this time he managed 88.

Don't underestimate these eight.

Each of these types of shocks is the most brutal test of the muscles and bones in the whole body.

Each additional creation represents a breakthrough beyond previous limits.

He broke eight limits in one go.

This growth was not a short-term growth, but a gradual and subtle one; he didn't feel it deeply when he was besieged last time.

Now it's certain that Chen Huai'an is the one.

"Come on, Xiao An, these are all your favorite foods, eat up." Chen Sujin kept taking food out of the food box and arranging it, and also prepared chopsticks and water for him.

Chen Huai'an was very hungry and began to wolf down his food.

To Chen Sujin's astonishment, the two food boxes, enough for four people to eat their fill, were almost devoured by Chen Huai'an in a flash.

After finishing his meal, Chen Huai'an grinned and said, "Sis, I'm still hungry."

Chen Sujin: "..."

"I...I'll have the kitchen prepare some more." Chen Sujin really didn't know what to say, so she could only send someone to have the kitchen cook.

Honestly, she was terrified.

How can a person eat so much?

Although Xiao An used to have a big appetite, it was only slightly larger than the average person's, not to this exaggerated extent.

But then she thought about it again and realized that Chen Huai'an was also incredibly strong. Chen Sujin felt relieved and joked, "Xiao An, it's a good thing you're a high-ranking official now."

"Otherwise, there won't be enough food for you at home."

Chen Huai'an was somewhat helpless; he really was eating more and more.

This is understandable, though, as energy cannot be created out of thin air, and his ever-growing, terrifying strength is also being consumed in great quantities.

But compared to that, none of these are problems.
