On the vast gallop road, a huge convoy is slowly advancing.

At the head was a guard of honor consisting of sixteen chariots.

Hundreds of heavily armed cavalry, following them, stood guard on either side of the convoy.

In the center, there is a large luxury cart, pulled by four horses, and it walks smoothly on the gallop.

Brocade covered the interior of the car, and two maids, carrying fruit and refreshments, knelt on either side of the carriage, so that the owner of the car could enjoy it at any time.

"Your Majesty, you're about to arrive at Luoyang...... a general in armor rode to the side of the cart and reported.

"Oh......" The man who had been sitting in the car, eating all kinds of melons and fruits, nodded, and then stood up, like an iron tower, with a strong body, enough to make future generations of weightlifters ashamed.

"Are you going to Luoyang?" He carried the sword at his waist and said, "The last time the widow returned to Chang'an was three years ago......

"I miss it......"

Perhaps thinking of something interesting, he stretched out his hand and asked left and right: "By the way, the widow heard that there has recently been a lieutenant in Chang'an City, who is known as unstoppable?" ”

When a eunuch dressed in brown heard this, he reported: "Returning to the king, there are indeed relevant rumors, it is said that the surname of this servant is Zhang, and after he stays, His Majesty likes to promote the waiter to the middle of the wait...... A month ago, the late Captain Shui Heng pointed to the embroidered messenger Jiang Chong to instruct the assassin, and wanted to assassinate this servant, but he was killed and captured by him with his bare hands......"

The sturdy man listened, his face filled with joy: "In this way, the widow can have a good time when he returns to Chang'an this time!" ”

He seemed to see the tigers, leopards and brown bears raised in the upper forest garden.

Maybe I can meet a confidant this time.

"The king......" The eunuch looked like he wanted to say something, and he didn't dare to say it directly.

"How?" The man asked with a dignified face, "Is there any problem?" ”

"King Qijuan, the slave maid heard that Zhang Shizhong, known as 'Zhang Chiyou', is known as 'Zhang Chiyou', who is known for his courage and the favor of the Son of Heaven, and he is very domineering, and he once said to people in private: Even if the king of Guangling is here, I will capture it if I bind the woman!"

"Really?" When the man heard this, his face immediately flushed, and his anger burned like a fire.

"The slave maid just heard about it, and I don't dare to ......guarantee it," the eunuch heard this, and said with sincere fear: "However, this matter was heard by the slave and maid from several nobles in the palace......"

"Shaft An dare to despise me?" The man's hand, holding the hilt of the sword tightly, actually left a deep mark on the hilt!

At this moment, in his heart, the anger was as hot as magma.

He can not care about women in this life, or he can not care about gold.

But, no one can despise and insult his force!

"When the widow arrives in Chang'an, I want to see your bravery, can you capture me?"

Listening to his words, a smile appeared on the corner of the eunuch's mouth.

It's so easy!

Just one word can anger this king!

However, over the years, hasn't everyone fooled him like this?

If you want this king to hate someone, just say in his ear that this person despises his force.

The king will be like an angry boar, recklessly attacking.

……………………………………

Almost at the same time, in the north of the galloping road, a convoy of the same magnificence drove on the avenue of Zhao State.

In the center, surrounded and protected by the army, on a large cart, a middle-aged nobleman was buried in a desk, holding a ruler and working patiently on a circle.

He worked so carefully that he turned a deaf ear to everything outside the world.

It wasn't until a long time that he finally smiled, stroked his palms and praised: "Sure enough! After the ninety-two equal divisions, pi should be 3.14......"

"Zhang Sheng is really a genius in the way of mathematics!"

"This time in Beijing, the widow may be able to ask for advice in person, please teach the method of abacus, or even more advanced arithmetic......"

For him, his whole life now is only pursued for one thing - arithmetic.

As for what power or great deeds, it is not within his consideration.

The reason is very simple - his relationship with the current prince is very deep.

Although the two are not brothers of the same birth, they have similar personalities and belong to the kind of people who are quiet and kind.

The only difference is that the prince likes literature, while he is obsessed with mathematics.

Since he was sealed to the northern Jicheng and called himself a lonely widow, he has devoted all his resources to collecting and snare arithmetic scholars and arithmetic books from all over the world, and established a paradise for arithmetic in that border fortress far away from the Central Plains.

In Yan Country, it doesn't matter if you don't know how to write articles.

As long as you are good at math, you can live a life of fine clothes and food.

Although the country of Yan is bitter and cold, the king of Yan is not poor!

Just by relying on the monopoly of the fur trade with Wuheng, Yan Guo's annual income is thousands of gold.

Therefore, all the arithmetic people in the world know - there is no food, no clothing, King Yan will send it to us; There are no sisters, no concubines, King Yan will prepare for us.

In today's world, King Yan is the hope and hope of mathematicians all over the world.

Yan Kingdom has also become the place where the atmosphere of Han mathematics is the strongest and most developed.

This atmosphere even affected the scholars of the Yan Kingdom, the scholars of the Yan Kingdom, who in recent years have been famous for their proficiency in arithmetic.

The reputation and image of the Yan Kingdom have gradually been reversed, from the bitter cold country of the past and the place of the back to today's 'holy land of mathematics'.

As a monarch who is devoted to research and obsessed with mathematics.

The king's arithmetic level is naturally not bad.

It can even be said that he is a top arithmetic who is outstanding!

Even his favorite concubine, Mrs. Huarong, is a top female mathematician, and the husband and wife sing and sing with each other, creating a good atmosphere of respect and importance for mathematics in the Northland.

He even began to expand his research from pure mathematical geometry to astrology and other fields.

"The King...... There is a visitor from Chang'an who asks to see ......" At this time, a eunuch came to the car to report.

"Visitors from Chang'an?" Liu Dan squinted his eyes, he has never been involved in the affairs of Chang'an, and every time he enters the court, he basically does not interact with the ministers of foreign dynasties (this is because there is no need at all, he cannot have a chance to inherit the throne, although he is the third, but his mother's status is not high, and the foreign family is weak, even if the prince falls, it will not be his turn to be in that position).

However, now a visitor from Chang'an has inexplicably appeared to approach him.

What does he want to do?

Liu Dan shrunk his neck, subconsciously remembering the countless tragedies in his family's history.

So he asked, "Who are the guests?" ”

"The son of Kwangluxun......"

"Han Shuo's son......" Liu Dan's eyes rolled, waved his hand and said: "Go and tell the guest, just say that the widow is sick today, and it is inconvenient to see each other, and ......I will talk about it another day."

Although he has always studied mathematics, he has not been unaware of the government.

In fact, he cares more about the government than anyone else!

Because, now he only wants to climb the peak of mathematics.

However, this requires a stable and peaceful environment, and the change of government and government is directly related to the stability of the world.

Therefore, he knew that there seemed to be a strange atmosphere in Chang'an City now.

Under such circumstances, Guanglu Xun Han said that he sent his son to intercept him on the road of pilgrimage to Chang'an.

Nothing good is true.

I'm afraid that they either want to play intrigue or play tricks on him.

He's not that stupid!

"But ......," said the eunuch, "the guest said that if the king did not see him today, he would surely regret it later!" ”

"Regrets?" Liu Dan blinked, was this threatening him?

Threaten the third son of today's son, the Yan King of the Han Empire?

Do you really think mathematicians are easy to bully?

Although Liu Dan has a quiet personality, he has been the king of Yan for 20 years, and he is inevitably infected by the folk customs of Yan country.

There is such a stubborn smell in his bones.

"Go tell the guest......" he got up and said, "I never regret my widow's life!" ”

"No!" The eunuch took the order and left, and returned a quarter of an hour later, and said to Liu Dan: "My lord, the guest said that he has in his hand the fifteen volumes of the slips collected by Zhang Cang, the Marquis of Beiping......

"Ah......" Liu Dan heard this, and immediately said: "Hurry up, please!" ”

During his years in the Yan Kingdom, he has always been committed to collecting and sorting out any characters and slips left by Zhang Cang, the Beiping Wenhou.

Because of this, Zhang Cangnai is the strongest arithmetic master in the history of the Han Dynasty and a recognized mathmaster in the world.

Naturally, his collection of treasured and handwritten books are invaluable in Liu Dan's eyes.

A moment later, a young man was taken and came to Liu Dan, who was under heavy protection.

"Minister Han Zeng pays a visit to the king, may the king be blessed forever!" This young man is very handsome, and he looks like a father and an ancestor.

As soon as they met, he ordered someone to send Liu Dan fifteen scrolls of slips that were kept in a wooden box.

"My father heard that the king Suxi did arithmetic, so he specially collected the posthumous works of Wen Hou with a lot of money, and the king of Xian!"

Liu Dan took these slips, and immediately couldn't put it down, as if he had met a peerless beauty.

For a mathematician, perhaps mathematics itself is a world that is always full of novelty and excitement.

Everything he wants, he can get from this world.

In that case, everything else becomes irrelevant.

"Guangluxun is really too polite...... "Reluctantly ** these precious documents, Liu Dan knows that if he misses them, then it will be difficult to meet again in this life.

But......

Who is Guanglu Hoon Han? He doesn't know yet?

That's a notoriously scheming.

Such a person suddenly sent a son to give him such a precious thing, is it just to sell it?

Etiquette must be demanded by others!

"Guangluxun can have any entrustment for Qing to convey?" Liu Dan asked cautiously and vigilantly.

He can't help but be careless.

Just because he was the King of Yan was enough for him to have deep suspicion and speculation about all the people who were deliberately close to him!

Because, before him, there were as many as five lineages of the Yan King of the Han family.

And these five genealogies are all not good to die! (Zang Tu rebelled, Lu Juan betrayed, Liu Jian was killed by Empress Lu, Lu Tong was punished by the princes and ministers, Liu Ze was finally passed on for three generations, and it was also gg)

He didn't want to be the sixth at all.

To some extent, he is obsessed with mathematics, and he also has this in mind.

It can't be said that even a Yan King, who is obsessed with mathematics, can be taboo, right?

"My father ordered his ministers to come to see the king, but he wanted to ask for the king's help......" Han Zeng bowed his head and bowed.

"What's the matter?" Liu Dan is more cautious, what Guangluxun can't do, let him come? There's no problem here, ghost letter!

"My father has a gap with the prince and Li Yu, and now Li Yu wants to serve as a servant, and my father wants to ask the king to speak in front of the Son of Heaven at the right time to prevent Li Yu's ascension to ......" Han Zengdun bowed his head.

"That's it?" Liu Dan didn't believe it, Han said that he sent his son so far away, just to say a few bad words about Li Yu in front of his father?

Is there such a simple thing?

"How dare the minister deceive the king?" Han Zeng kowtowed and bowed: "It's really that's all!" ”

"If the king can promise, even if it can't be done in the end, my father will be grateful...... Han Zeng said: "Don't hide it from the king, my father is close to Zhang Zizhong, if the king can agree, my father is willing to introduce Zhang Shizhong to the king......"

Hearing this, Liu Dan was finally moved.

That Zhang Zizhong is the power to crack pi!

The theories of circumcision and density opened the door to a new world in Liu Dan's heart.

And the abacus and abacus he created and invented made him ecstatic, and he got it like a treasure.

He had long wanted to communicate with such a great sage in private.

It's just that the other party is a servant, and he doesn't dare and can't take the initiative to meet in private.

Now, Han Zeng's proposal, like the whisper of the devil, made him finally nod and said, "Since this is the case, the widow will agree......"

It's just that Dad is looking for an opportunity to say a few bad things about Li Yu, and there is no big problem.

Even if he had, he would be able to see the wind and rudder!

Han Zeng listened, but he was overjoyed, and he breathed a long sigh of relief in his heart.

Everything is going well on his side, and presumably King Guangling's side is about the same.

In this way, the king of Yan and the king of Guangling all fell into his father's calculations.

There are two kings who are willing to be pawns, and they are afraid that they will not be able to handle one Zhang Zizhong?

Not to mention, there is also a king of Changyi!

Unlike King Guangling and King Yan, King Changyi doesn't need his father to exert himself, he will definitely be hostile to that Zhang Zizhong.

The reason is simple.

The teacher of Liu Ji, the king of Changyi, Taifu Xiahou Shichang is his own person!

With this old man here, Liu Ji will definitely hate that Zhang Zizhong.

So the three kings are enemies.

As long as you do it well, if nothing happens, this Zhang Zi will not survive this winter!

He's going to die.

You have to die!

If he doesn't die, the problem will be in trouble.

Zhi Jinwu has traced some sensitive issues and found some evidence.

If you continue to investigate, you may have to shake off the old bottom of many people.

And the only thing that can stop Zhijingo from continuing to pursue is to kill the lieutenant who caused all this to happen.

As long as he dies, the Son of Heaven will probably have no interest or interest in pursuing it.

When the time comes, find him something new, divert his attention, and the matter will be delayed.
