Emperor of the Tang Dynasty

"His Royal Highness the King of Chu, I have basically mastered all the loan bookkeeping methods."

Wu Zetian was a little nervous when he saw Li You up close. He didn't know what to say, so he could only report his progress first.

Li You smiled approachably and said, "Juan'er is really talented and intelligent. It only took less than a day or two in total to learn such a complicated accounting method."

Wu Zetian's cheeks flushed slightly and his heart was beating wildly - His Royal Highness the King of Chu even started to call him "Juan'er" so intimately!

This made Wu Zetian take a few deep breaths before continuing: "Your Highness is too good... The other students have more foundations than me, and at most they can master all the loan bookkeeping methods in a short period of time than me."

Afterwards, Wu Zetian asked in a low voice with a trembling voice, "Then...then can I call you teacher directly?"

"of course can."

Li You nodded, Wu Zetian looked overjoyed, and asked again, "Teacher, what are we going to do next? Are we going to check the ledger that was handed in?"

"Yes."

After hearing Li You's reply, a worried look flashed across Wu Zetian's face.

"However, teacher... There are so many accounts, if you use the running water bookkeeping method, even if you buy something small or miscellaneous, it will be written down directly, although re-liquidation using the debit bookkeeping method can quickly find the wrong thing. place, but even so the base is still too large!”

Wu Zetian's implication is that the running water bookkeeping method will lead to a large amount of information in the ledger, plus the time required for calculation, even if there are [-] people, it is not enough.

Of course Li You understood this and knew that Wu Zetian was trying to persuade him to find more people, otherwise ten days would definitely not be enough.

"You don't have to worry about this, this king has his own way."

Listening to Li You's indifferent words, Wu Zetian felt as if he had returned to a few days ago. When Li You faced this difficult problem that she thought could not be solved no matter what, he seemed to be so indifferent.

"Sure enough, the teacher has a solution!" Wu Zetian immediately said excitedly, "I knew it! The teacher's ingenuity must be a hundred times better than mine!"

Wu Zetian's fan-type bragging makes Li You's cheeky feel a little embarrassed.

But in any case, Li You's heart is still very useful to be so touted by the queen who will hang the sky in the future.

"Let's see... The things I commissioned the Ministry of Industry to make are almost finished. You can take a look at it as a teacher."

Although Li You is only two or three years older than Wu Zetian, he has begun to call himself a teacher. After all, being the teacher of the Great Sage Emperor Zetian is so exciting!

Moreover, the reason why Li You treats Wu Zetian a little bit is because he has the idea of ​​cultivating Wu Zetian to be a great help to him.

Although he knew that Wu Zetian would become the emperor in the future, but that was when he was out of control, and there were still countless coincidences. Li You was confident that with his own control, he would not give Wu Zetian a chance. Wu Zetian will definitely be in his hands for a lifetime. Can't turn over!

Being able to become an emperor and a famous emperor with outstanding political achievements also shows that Wu Zetian is a rare and extremely powerful talent, so how could Li You let go of such an emperor's talent?

At this time, Wu Zetian didn't know about these things, she just followed Li You with great excitement, feeling that her relationship with the teacher had gone further.

After walking to the Ministry of Works, Duan Lun, Minister of the Ministry of Works, came out to greet him cordially.

This scene also saw Wu Zetian secretly surprised. Although she knew that Mr. Duan was playing for Li You, she did not know that the relationship between the two was already so good.

"I have seen His Royal Highness the King of Chu, may I ask who is next to you...?"

Duan Lun looked at Li You inquiringly, and winked a little. After all, he looked at the girl next to Li You, her beauty could be said to be of national beauty, and she was as beautiful as a fairy at a young age.

In the original history, the reason why Wu Zetian entered the palace was because Li Shimin heard that Wu Zetian's appearance and behavior were extremely beautiful, so he specially called her into the palace, and even gave her the name "Wu Mei", you can imagine how far and near the beauty of Wu Zetian famous!

"Don't think too much about Duan," Li You smiled, "This is Wu Jue, the daughter of the deceased warrior Yu."

"It turned out to be Lord Wu's beloved daughter..." Duan Lun was a little surprised.

"Master Duan, I don't know what I commissioned you to build, can you build it?"

Duan Lun said sternly, "Please rest assured, His Royal Highness King Chu. Of course, I will do my best to do what you told me to do. The number is exactly one hundred and one!"

"That's good, take me to see it," Li You smiled, "--our winning artifact!"

Chapter 477 The Abacus Artifact!

"Teacher, what is the magic weapon you are talking about?"

Wu Zetian couldn't bear the two of them playing dumb riddles, so he couldn't help asking.

"Its name..." Li You smiled, "Abacus."

"Abacus?" Wu Zetian was startled, "What is that?"

Of course, Wu Zetian did not know about the abacus that only appeared in the Northern Song Dynasty. Although it is said that the earliest prototype "abacus" appeared in the late Eastern Han Dynasty, this kind of uncommon history is not known to Wu Zetian.

Li You said: "Abacus is a special tool. After I teach you how to use it, your calculation speed will be increased tenfold and one hundred times! In short, you will know it after you see it with your own eyes."

"Oh……"

Wu Zetian nodded ignorantly and followed Li You to find out.

What Li You said is true. In the later generations when computers have been widely used, the ancient abacus has not only not been abandoned, but has been in the ascendant in many countries because of its advantages such as flexibility and accuracy.

Even the people of the Celestial Dynasty often compared the invention of the abacus with the four ancient inventions!

Due to the convenient and fast calculation of the abacus, even the most advanced electronic calculators cannot completely replace the function of the abacus. UNESCO has also officially listed the abacus as an intangible cultural heritage of mankind.

And this kind of calculation artifact was placed in the Tang Dynasty, it was as if everyone handed out a calculator, and it had the terrifying computing power of crushing level!

About abacus Li You learned it in an interest class in elementary school. When he practiced abacus well, it was even faster than using a computer directly!

After Wu Zetian saw the abacus with his own eyes, not only did he not realize it, but he was even more confused.

"This...is that the winning artifact that the teacher said?"
