Inside the Qin Palace, it is magnificent.

The First Emperor sat in front of the desk, looking at the yellow paper spread out on the desk, and gently stroked the strange symbols on the paper with one hand.

He turned his head to look at Zhao Gao, who was standing beside him, who was specially responsible for ghostwriting and reviewing for him, and asked, "What do you think of the new numbers made by the martial arts marquis and the imperial history under the pillar?" ”

Zhao Gao said with a smile on his face: "Chen thinks that these new-style numbers are simple and easy to write, most of them can be completed in one stroke, and they are far more convenient than old-style numbers when calculating, and the same is true for those addition, subtraction, multiplication and division symbols." If this new type of number can be promoted to the world, it will definitely improve the administrative efficiency of all parts of our Great Qin, which is a great benefit. ”

The First Emperor's jaw.

The numbers in front of him looked weird, as if they had been written at random, and his eyebrows furrowed when he first saw them.

But when he used these numbers to check and calculate them in person under Zhao Tuo's explanation, he immediately found that this thing was really very convenient.

Mathematics is one of the most important things in the administration of the state.

The annual tax revenue needs to be used, the fiscal expenditure needs to be used, and the officials also need to be used for the upper calculation and evaluation. In addition to this, what else is the management of prisoners, construction, handicrafts......

This is something that is needed for everything, and if this new set of digital symbols can improve efficiency and convenience, it will be a great increase in administrative efficiency for the whole country.

Now is the time when the Qin State has just unified the world and everything is just beginning, unlike some dynasties in later generations who often resist new things with the immutability of the law of their ancestors.

In Qin Shi Huang's view, as long as this thing is really useful to the country and can effectively improve the efficiency of state administration, then everything can be changed.

He has already unified the world's writing, and if he unifies the world's mathematics, it is not impossible.

Not to mention, this set of numbers was specially designed by his favorite son-in-law for his Great Qin, and it contains a unique and beautiful meaning.

"69 Transformation indicates that my Great Qin is the extreme of the world, and I will always enjoy the inheritance of eternity. What a 6! ”

The First Emperor admired, and at the same time, the corners of his mouth hooked again, and he whispered: "Change to Qin number on the basis of the public loss number, good Zhao Tuo." I really want to see what is hidden in his head that I haven't taken out? ”

With the approval of the First Emperor, this set of Qin number symbols presented by Zhao Tuo, the Marquis of Wugong, and Zhang Cang, the Imperial History of Zhuxia, were immediately sent to the departments that used more mathematics such as Zhisu Neishi, Tingwei, and Shaofu for experimentation.

If no problems are found in actual use, then it will be further extended to all counties in the world.

Regarding the merits of dedicating this set of Qin numbers, the First Emperor did not hesitate to reward them, and selected a bunch of treasures from the six countries to give to Zhao Tuo. Shi Zhang Cang was given a knighthood as a sign of commendation.

"Wugong Hou is not only unparalleled in the world in mathematics, but also has a pure personality, what a good person. Qin Shu was obviously deduced and completed on the basis of the public figures, and I, Zhang Cang, were just responsible for checking the calculations for him, and he even gave him a great achievement. ”

Zhang Cang patted his fat belly and kept sighing.

Zhao Tuo took out the new set of numbers, and after he went back to check it carefully, he found that no matter how he was picky, he couldn't find any mistakes and mistakes. It seems that this set of digital symbols has been made by countless people after hundreds of years of deduction and supplementation, and it is very mature and perfect in all aspects.

Zhang Cang was very puzzled by this, but Zhao Tuo's statement that it originated from the male loser was very convincing, so he could only make up the new number invented by the male loser in his own brain, and its descendants supplemented it from generation to generation, and finally Zhao Tuo carried out the process of perfect summary.

Zhang Cang actually didn't have any strength, but was written together by Zhao Tuo's recital, and he received a great contribution in vain. After receiving such a big favor, Zhang Cang was naturally very grateful, and his friendship with Zhao Tuo was heating up day by day.

It's just that after Zhao Tuo was invited to Zhang Cang's mansion as a guest, he was greatly stimulated.

"This fat man is really blessed with all the blessings of all people!"

Zhao Tuo's tone was a little sour.

is nothing more than anything else, precisely because there are too many women in the Zhang Cang family.

This guy is obviously a big fat man with a mountain in shape, not to mention being lonely in the future generations, it is also difficult to get married, but in fact, there are more than 20 concubines in Zhang Cang's mansion.

These women are not beautiful and stunning, but they also have their own appearances, especially as Zhang Cang intends to show off in front of Zhao Tuo, when he clapped his hands proudly, and when these more than 20 neatly dressed women walked out together, it was really dazzling.

And Zhang Cang, the fat man, spoke and acted politely when he met for the first time, but after getting acquainted with Zhao Tuo, he showed his sullen side.

"Prince, I'll tell you. This woman still has to be changed often, a woman can't spend two nights, and it is changed every night. It's a pity that I'm shy now, I can't afford to raise more, and when I have money in the future, I should raise hundreds of women in the mansion, singing every day, and grooming every night, this is the beautiful thing in the world. ”

Listen to Zhang Cang there to publish his great dreams and try to impart some experience to Zhao Tuo.

Zhao Tuo's teeth itched when he heard this, and he didn't understand how such a promiscuous person could live to be hundreds of years old.

Could it be that if you are fat, you can defend yourself against being hollowed out by beauty?

In the face of Zhang Cang's various boasts, Zhao Tuo could only focus on this, and took the opportunity to turn the topic to other aspects, not wanting to listen to it more.

At the time of the final parting, Zhang Cang had already introduced Zhao Tuo as a confidant, showing the good habits of nobles in this era when interacting, saying that he wanted to give a concubine to Zhao Tuo.

Zhao Tuo didn't say anything, just stared at him silently.

Zhang Cang was smart, and when he saw this scene, he immediately reacted and was shocked.

He said embarrassedly: "I am talking too much about this matter, but the prince must not tell the eldest princess." ”

As he spoke, he looked at Zhao Tuo's eyes full of sympathy.

Zhao Tuo rolled his eyes and secretly vowed never to be a guest at the fat man's house again.

However, all the thoughts in his heart turned into tenderness for his wife when Zhao Tuo returned home.

In the mansion of the Marquis of Wugong.

The eldest princess Yingyin Yan was dressed in a light silk dress, leaning on the couch, and Zhao Tuo was sitting next to her, stretching out a hand to gently caress her belly.

"It seems to have moved."

Zhao Tuo said with some surprise.

Ying Yin glanced at him and said with a smile: "It's only been a few months, and I didn't feel it." ”

Zhao Tuo smiled, looked at the woman in front of him, and glanced at his son who was sitting in the corner of the house playing with toys, his eyes were full of happiness.

"It's supposed to be a daughter this time."

Zhao Tuo said softly, with a hint of hope in his eyes.

Now that he has a son, he naturally hopes to have another daughter, so that both children will be happy and happy.

Ying Yin Yan covered her mouth and chuckled: "You still want a daughter, isn't it good to have another son?" You don't see how much my sister-in-law wants to have a son. ”

Because Yingyin Yan and Fusu are brother and sisters, the movement between the two families is more frequent, and between you and me, Yingyin Yan has some friendship with Fusu's wife Li.

The affairs of the daughter's family, chatting in private, will inevitably fall on childbirth.

According to Yingyin Yan's statement, the Li family also asked her about the magic method of how to give birth to a son, and her mind was full of thoughts about giving birth to a successor for the prince.

"Anyway, they are already pregnant this time, if they can really give birth to a son, the prince's position will be more stable."

Zhao Tuo laughed.

Speaking of this, his mind couldn't help but think of Fusu's weak appearance of walking a little vain and with dark circles under his eyes in the past two months.

At that time, Zhao Tuo was greatly shocked when he saw it, for fear that the disease left by Fusu in the north had not been cured, so he hurriedly asked.

As a result, he was stopped by Fusu and complained, saying that he was very hard during this time, and he was pestered by his wife every day, saying that he must conceive the eldest grandson for the royal family.

Fusu's character is benevolent, and in the face of the Li family's oppression with the royal heir and the righteousness of the family and country, and the pleading with the emotions of husband and wife, he can only admit it with his head down.

It is about the eldest grandson of the royal family, Zhao Tuo is not good at talking nonsense, and only tells Fusu to be sure to focus on his body.

Fortunately, Fusu's hard work was not without harvest, just some time ago, he excitedly told Zhao Tuo that Li was pregnant.

Fusu's crying appearance with joy made Zhao Tuo unsure whether he was happy to have a child or happy to be free from the affairs in the room.

However, Fusu can have descendants, and Zhao Tuo is naturally very happy.

"Fusu has a child, firstly, the prince's position is more stable, and secondly, it also shows that he is not infertile, and there is a successor to this empire."

Zhao Tuo breathed a sigh of relief, he was actually worried that Fusu had not yet given birth to an heir.

Fusu's marriage is still in front of Zhao Tuo. As a result, Zhao Tuo's sons are more than two years old, and Fusu has not yet had a child born, how can he not worry about this matter?

Zhao Tuo's breath was only halfway out, and he was shocked by Yingyinyan's words and sucked it back.

"Didn't I go to the Prince's Mansion today?"

"My sister-in-law said that our two families were pregnant almost at the same time, and if we were born as men and women in the future, we might be able to get married."

Ying Yin said with a grin.

Cousin marriage is a very normal thing in these days.

Zhao Tuo was shocked when he heard this, and said, "No! This marriage cannot be agreed! ”
