After Xiao Guizi sighed, he turned around and left the 21st century. But Zou Fengchi was concentrating on fiddling with the abacus in his hand.

Looking at Zou Fengchi's serious appearance, Li Chengqian opened his mouth and said: "This king has already mentioned it to the queen mother, and the queen mother has agreed to marry you and Bi'er." ”

"I know the prince. What the? What did you say, lord? Zou Fengchi nodded in agreement, and then suddenly raised his head and asked Li Chengqian.

"This king said, your childhood sweetheart Bi'er is about to become your bride. When the time comes, the king will organize a grand wedding for you. ”

"It's just that Bi'er still has to work as an errand in the palace, and she will only be given a few days off every month to reunite your husband and wife." Li Chengqian said with a smile.

This time, Zou Fengchi understood it, so he hurriedly stepped forward to salute Li Chengqian and said, "The prince's kindness today is remembered by his subordinates. ”

"I, Zou Fengchi, make an oath here, in this life and this life, I will look forward to Li Chengqian's horse, and if I have two hearts, the heavens and the earth will be destroyed. The soul is reduced to the Nine Hells of Purgatory, and it will never be reborn. ”

Li Chengqian stretched out his hand to help Zou Fengchi up, and then said with a smile: "The people who follow this king are the brothers of this king. How can this king not think about your happy life? ”

Bi'er is the personal maid of the eldest grandson queen, and it stands to reason that such a woman has only two endings in the end. One is to accompany the queen to die alone, and the other is a woman who will become the emperor.

Now that he can tie the knot with Bi'er, this is something that Zou Fengchi never dared to think. So at this time, Zou Fengchi was really grateful to Li Chengqian.

Later, Li Chengqian carefully explained the Arabic alphabet and various operations to Zou Fengchi.

Addition, subtraction, multiplication and division are not difficult for Zou Fengchi. Nowadays, with Arabic numerals, it's even easier.

However, at this time, Li Chengqian found that on the ledger, the font was outlined with brush characters. It seems that the whole ledger is very messy.

So Li Chengqian bought a quill pen in the grocery store. Then he used a quill pen to draw the account books of later generations on paper.

and explained to Zou Fengchi how to fill in the entry and exit accounts. And told Zou Fengchi that from now on, this is the ledger style of the 21st century. Moreover, all the account books will be provided by Li Chengqian in person.

It took nearly half an hour or so, and Zou Fengchi figured it all out. This is also because Zou Fengchi originally had a foundation in this area.

If it were to be replaced by an ordinary person, it is estimated that even if Li Chengqian talked about him for three days and three nights, he might not be able to make the other party understand much.

After Zou Fengchi mastered it, he demonstrated it several times in front of Li Chengqian. In the end, Li Chengqian nodded with satisfaction.

……

"Ladies and gentlemen, this king is no longer the crown prince of the dynasty. If you think that following this king now will have no future. Neither will the king force him to remain. Li Chengqian said.

"What did the prince say, I Cheng Chumo befriended you, the prince. Your personality is refreshing, and I admire Cheng Chumo very much. As for what a prince doesn't have a prince, I have never taken it seriously. Cheng Chumo was the first to speak.

"Although the prince is not the crown prince now, he is the eldest brother of the princess. In two days, I should marry the princess. At that time, the prince will be my royal brother. Changsun Chong said with a smile.

As for Lu Yan and Tong Shougang, it is naturally impossible for them to choose to leave Li Chengqian because of the change in Li Chengqian's identity.

Seeing that everyone had expressed their hearts, Li Chengqian said with a smile: "Since you believe in this king, this king will give you a bright future." ”

"The king has asked his father for a decree, and his father has promised the 21st century. Whether it is a business or a worker, it is not classified as a lowly citizen. ”

"If anyone has a career, as long as you show the talent you deserve. The king will also recommend him to the court as an official. ”

This time, Zou Fengchi, Lu Yan and Tong Shougang were not so calm. Shinong industry and commerce are hierarchical differentiation that has been passed down for thousands of years.

Craftsmen are known as skilled craftsmen, although their status is a little higher than that of merchants. But they are definitely not taken seriously, and no one even takes them seriously.

And the status of businessmen is even lower, although there are thousands of family wealth, but it is difficult to get into the elegant hall. Even if you eat delicacies and seafood every day, you will not be able to enter the aristocratic circle.

Now that Li Chengqian can make the emperor issue such a holy decree, there will be an infinite future by Li Chengqian's side.

So the three of them hurriedly knelt on the ground and bowed to Li Chengqian. In the Tang Dynasty, except for parents, even if you see the emperor, you don't need to kneel. It can be seen from this that Li Chengqian's status in their hearts is already comparable to that of his parents.

Li Chengqian stretched out his hand to help the three of them up, and then said: "There are about 20 days left, and the 21st century will be officially opened." ”

"I have asked my father to personally mention this plaque, and he will be our golden signboard in the 21st century in the future."

After Li Chengqian finished speaking, he took out Li Shimin's ink treasure from his arms. Then he handed it directly to Lu Yan and asked Lu Yan to copy him into a signboard.

When Lu Yan opened Li Shimin's ink treasure, he couldn't help but be stunned. Pointing to 21 on the paper, he asked Li Chengqian: "Didn't the prince say that it was called the 21st century, what is the emperor writing here?" ”

It turned out that Li Chengqian actually asked Li Shimin to write 21 in Arabic numerals. So Lu Yan naturally wouldn't recognize it. Not only Lu Yan, but everyone present was puzzled except for Zou Fengchi.

At that time, Li Shimin was also very puzzled, and later under Li Chengqian's detailed explanation. It was only then that Li Shimin understood the wonderful use of these Arabic numerals.

That's why the 21 was written down in Arabic numerals, and Li Chengqian was also put in charge of promotion. Strive to maximize the influence of Arabic numerals. And also gave it a new name, called Zhenguan Counting.

In the end, Zou Fengchi stood up and explained the 21 words to everyone. Only then did everyone understand that it was not Li Shimin who wrote it wrong.

Later, Li Chengqian asked Zou Fengchi to design the account book, as well as Arabic numerals and abacus. I explained it to everyone present. Of course, there is also the quill pen in Zou Fengchi's hand.

Hearing that, a few people were relishing, but Cheng Chumo was at a loss. And slowly closed his eyes, and then there was a sound of snoring.

Li Chengqian did not blame Cheng Chumo for this. After all, there are specializations in the art industry, and everyone's expertise is different. And Cheng Chumo is not good at these.

However, Changsun Chong couldn't look at it, and reached out and directly pushed Cheng Chumo, waking him up. And glared at Cheng Chumo fiercely and said, "Is this where you sleep?" ”

Cheng Chumo wiped the saliva from the corner of his mouth, and then said embarrassedly: "I didn't sleep well last night, and I will definitely not next time." ”
