"My lord, you train day and night, naturally you don't have time to take care of the third prince, he has no one in the mansion to care, naturally he is used to it, it is better for you to send him to the county king in Tianshui, the county king is the same age as the third prince, I think there is something to say between them, and His Royal Highness the county king is wise and martial, and the third prince will make great progress by his side."

"Hmmm! This makes some sense, but can this prince promise the third child to go to him? ”

Zu Ti had some doubts.

"Then the lord will personally write a letter to His Highness, after all, he can occupy Tianshui Our people have made a great contribution, and Xu Da also said in the letter, the other party is very benevolent, and there should be no problem with your request."

Zhu Yuanzhang analyzed.

"Alas, for this rebel, I'm so heartbroken! Okay, I'll write a letter myself. ”

A few days later, the letter was in Liu Yuetian's hands.

"Brother Xu, Zu Taishou asked you to go back, but Brother Chang can stay."

Liu Yuetian was a little reluctant to Xu Da, but there was no way, he and Chang Yuchun were both generals under Zu Li, and it was already good for people to leave Chang Yuchun to him.

"Your Royal Highness, Tianshui is only a threat to Daqin, and the city is strong and easy to defend and difficult to attack, with you to guard, plus Yuchun and Shile brothers, this city is worry-free, but it is a key place in the depths of Henan County, and it is on the verge of the princes of the three parties, so I am very careful at all times, so Lord Taishou will order me to go back."

Xu Da explained.

"It doesn't matter, talents like Brother Xu and Brother Chang are naturally needed there, and besides, you are also Zu Taishou's people, I won't be embarrassed for him, it's just ......... This ancestor Taishou proposed to let his third son come here to study? Why is that? ”

"What? The third son? ”

Hearing this name, Xu Da and Chang Yuchun's faces changed slightly.

"What? This third prince is also a powerful figure? ”

Liu Yuetian asked with a smile.

"Alas, Your Highness doesn't know anything, this third prince is a strange person!"

Xu Da sighed.

"Strange people? How? ”

"This third son's name is Zu Chongzhi, he is young and intelligent, and Taishou loves him very much, but when he reached his teens, the third prince was obsessed with something......... What is the method of arithmetic, and what are you often doing......... What kind of circumference or something, this makes Lord Zu very annoyed, let the third prince come over this time, I'm afraid I want him to learn from His Royal Highness! ”

Xu Da replied.

"Oh? Mathematician! ”

Liu Yuetian's eyes lit up and he became interested.

"Mathematicians? What do you mean? ”

No one else understood what this mathematician was.

"I can't believe that there are mathematicians in this world! Yes, mathematics is the highest discipline of natural science, and anyone who has great wisdom will surely discover all kinds of mathematical mysteries between heaven and earth, but I did not expect that the son of this ancestor Taishou is one, and this person will definitely be used by me. ”

Liu Yuetian was a physicist in his previous life, and he is naturally not bad in mathematics, looking at the development of human history, what is the biggest thrust of human progress? That is science, and it is natural science, it is by no means a battle between you and me, I fight you, of course, science will make faster progress in the state of human struggle, but in the final analysis, the development of human beings still depends on science, and war is just a reason for the faster progress of science.

Liu Yuetian also wants to teach people all kinds of science, but his survival is still a problem, where is the time to teach others to learn? Second, this chaotic world is still in the era of cold weapons, and the princes of all parties are fighting for power, and there is no time to engage in any natural science, and people are also in the thinking of ignorance and slavery, and it is impossible to give birth to the germ of exploring all kinds of mysteries of nature in this state of thinking, which is the so-called scientific thinking.

But now I heard that a young man named Zu Chongzhi was actually quite interested in this Tao, and it was a treasure for him.

"Bring me a pen at once, such a genius must not be put in the hands of a fool, he must come to me!"

Liu Yue Tianfang brought a paper mold and quickly replied to Zu Li.

"Brother Xu, you give this letter to Zu Taishou, he will know it at a glance."

Xu Da took the letter and looked at it, and it naturally praised and thanked Zu Ti and the like, but there was also praise for Zu Chongzhi in it, saying what kind of young genius he was, what he would be famous all over the world one day, and so on.

"Can Zu Chongzhi still shine and be famous all over the world?"

If he hadn't seen Liu Yuetian's wisdom and martial arts, Xu Da would have regarded him as the same person as Zu Chongzhi.

"Haha, Brother Xu, you guys! I don't understand what science is, once we apply science, what the seven princes are, all of them are fart! ”

Liu Yuetian If there is a submachine gun unit in this era, then how can others mix it! Kill him all, and it is a matter of minutes to unify the world.

Xu Da only left with fifty guards, and the rest was left to Liu Yuetian, who was also elated when Xu Da left, sitting on a Lu horse and an iron sword in his hand, this equipment would definitely make Zu Taishou envious and jealous.

Of course, in order to express his gratitude to Zu Ti Taishou, Liu Yuetian was not stingy, and also sent a Lu horse, anyway, it was just a matter of spending seven or eight hundred meritorious points, after occupying Tianshui, Liu Yuetian really did not lack meritorious merits, and the increased loyalty of the people of Tianshui alone allowed him to get more than 200,000 meritorious points.

sent Xu Da away, Liu Yue had to work without touching the ground.

These days, he is not idle, even not idle for a moment, occupying Tianshui means more things, the Liu family has been in the city for several generations, in the warehouse in the Taishou Mansion there are nearly one million taels of silver alone, and there are a lot of beautiful jade and gold, among which there are more than a dozen pieces of Kunlun white jade that made Liu Yuetian happy for a while, Liu Yuetian didn't care much about money or something, that Kunlun white jade is the raw material for making the general's seal, and in his eyes it is much more precious than gold, so all these Kunlun white jade were "filled with his own pocket".

As the victor, Liu Yuan's property is all Liu Yuetian, even if he takes all the million taels of silver for himself, no one will say anything, but Liu Yuetian's "three views" determine that he will not do this, these wealth is taken from the people, of course, it must be used by the people, for example, all the dead people, their relatives will be compensated accordingly, and if one person dies, he will be compensated for fifty taels of silver, the unified treatment of the injured, everything is free, and those destroyed houses, Liu Yuetian will pay for it; Liu Yuetian paid for the labor used to build the house.

And these are just emergency expenses, Liu Yuetian promised, from now on, the people in Tianshui City will be exempted from agricultural taxes for three years, and after three years, agricultural taxes will be charged according to one percent of income, and what education, medical care, etc. are all free, paid by the government, Liu Yuetian is almost about to move the welfare system of the human government in his previous life.
