"Dean, the student has also calculated the answer!"

"Wei Shuyu, good, very good, give the answer to Dean Kong!"

Wei Shuyu was robbed of the first place by Yu Chi Baoqi, and he was quite unwilling!

However, receiving Li Gen's verbal praise made him sit down happily.

"Dean, the merit award has also been calculated!"

Li Decheng got up and took the initiative to hand over the written answer to Kong Yingda.

Li Gen smiled and nodded.

Soon, many young men have calculated the answer.

Cheng Chuliang was the last to get up and hand it over to Kong Yingda.

Even so, this speed made the doctors of the country stunned.

They will never believe that these young men are all arithmetic geniuses that they have not met in a century!

"Dean Kong, please let the seniors of the Guozijian see if the teenagers' calculations and answers are correct!"

Listening to Li Gen's words, Kong Yingda smiled and nodded.

He took out the boys' answers from his sleeves and distributed them to the people of the country.

Call!

Call!

Call!

Everyone was stunned.

Because the answers are correct.

Because before they came, they had already known Tang Shu, and the answer of the students in front of them was 23!

The people who did not believe in evil exchanged students' answers, and it turned out that all fifty answers were the same.

The calculation method is very different from the calculation method in Sun Tzu's sutra!

Compared with the calculation method in Sun Tzu's arithmetic, it is much simpler and more direct.

"Champion Lang, today's trip is really an eye-opener for me."

"Can you also have a question to enliven the atmosphere of the school?"

Doctor of Accounting, Guozi, got up with a smile and spoke.

"Seniors, please ask questions, it is an honor to get the examination school of seniors!"

Although Li Gen didn't know this person, since he was Dr. Guozijian, he naturally had to be polite!

After all, at the beginning, he was under the Guozijian in the imperial examination, and the entrance examination for these teenagers was also completed in the Guozijian.

Reasonable and reasonable, Li Gendu has a sense of gratitude to Guozijian!

"Today, there are chickens and rabbits in the same cage, with thirty-five heads on it and ninety-four feet on it.

Guozi Doctor of Accounting, the voice is on the ground.

Li Gen smiled and nodded.

Signal everyone, hurry up and solve the problem!

The boys held quill pens in their hands and began to look down and calculate.

The rustling sound of the tip of the pen touching the paper made everyone embarrassed.

It's no wonder that the boys calculate quickly, and the speed of writing has an advantage.

"Dean, I'm done!"

"Dean, the students are also done!"

This time, Yu Chi Baoqi and Wei Shuyu stood up almost at the same time.

Li Gen smiled and nodded, it seems that Yu Chi Baoqi is quite talented in arithmetic.

Dr. Guozijian, stunned again!

Is this done?

It's too fast, isn't it?

Soon, all the young men handed in their answers.

Dr. Kuniko was stunned.

The answers on the fifty sheets of paper turned out to be all correct.

The rooster has twenty-three (23) and the rabbit has twelve (12).

Li Gen saw the real answer from the expression of Dr. Guozi's supervisor.

That's these teenagers, all of them have successfully answered.

"Students, start class now, today because of the seniors of Guozijian, come to the college to guide the work, and I will continue to solve the mystery of Tang Shu in the afternoon class."

Li Gen picked up the chalk and wrote a few simple math problems on the blackboard.

Then start teaching!

………

The more you listen, the more energetic you become, and the more you feel the changes and mysteries of Tang Shu!

Because of the cumbersome number that requires many text combinations.

If you use Tang number instead, it's just a matter of adding one or a few numbers.

One, ten, hundred, thousand, thousand......

The teenagers in the school also listened with relish.

Everyone forgets the time, and some only have the thirst for knowledge, the joy of having solved the test questions.

Those who have never experienced that feeling of sudden enlightenment will never be able to feel the joy of it.

"Today there are going out, there are nine embankments, there are nine trees on the embankment, there are nine branches on the wood, there are nine nests on the branches, there are nine nests on the nests, there are nine birds on the nests, there are nine chicks on the birds, there are nine feathers on the youngsters, and there are nine colors on the hairs.

Li Gen said as he wrote in chalk on the blackboard.

Everyone in the country was stunned, such a topic.

It will also take them a long time to figure out the answers.

And Li Gen's calculation method is simply appalling in terms of speed!

"Students, this question seems too difficult, but it is very simple to calculate with Tang Numbers!"

"Each of the nine embankments has nine woods, multiply nine by nine, and you get eighty-one woods."

Li Gen explained in Chinese, using Tang numbers to calculate on the blackboard.

"The wood has nine branches, multiply eighty-one by nine, and you get seven hundred and twenty-nine."

"The branch has nine nests, multiply seven hundred and twenty-nine by nine, and you get six thousand five hundred and sixty-one."

"There are nine birds in the nest, and multiply six thousand five hundred and sixty-one by nine, and we get fifty-nine thousand and forty-nine."

"The fowl has nine chicks, and multiply these fifty-nine thousand and forty-nine by nine, and you will get five hundred and thirty-one thousand four hundred and forty-one."

"The chick has nine cents, five hundred and thirty-one thousand four hundred and forty-one, and multiply it by nine to get four million seven hundred and eighty-two thousand nine hundred and sixty-nine!"

"Mao has nine colors, multiply it by four million seven hundred and eighty-two thousand nine hundred and sixty-nine and multiply it by nine, which is the final answer, four thousand three hundred and forty-six thousand seven hundred and twenty-one."

The Tang number on the blackboard is simple and clear!

The people of the country are completely convinced.

This problem, if you follow the previous algorithm, not to mention counting from sunrise to sunset, will definitely lose a handful of hair.

And the Tang number on the blackboard, used to calculate, is as simple as that!

It's just a string of numbers!

Li Gen has been teaching this class.

First, out of respect for His Majesty, because all the people in the country came by order.

The second is the respect for the predecessors of the Guozijian, these are all highly respected people of the Tang Dynasty.

They don't get up to leave, how embarrassed they are to get out of class.

Until sunset, Kong Yingda really felt sorry for Li Gen, so he touched the arm of Zhang Houyin, the priest of the country.

Zhang Houyin looked out the window and saw that the sun was already going down.

Although I was still unsatisfied, I had to get up and say goodbye.

"Zhuangyuanlang, listening to your class is better than reading for ten years."

"I didn't expect that time passed so quickly, so that Zhuang Yuanlang was tired!"

"The seniors are serious, and the younger generations are young and healthy, so they don't feel hard."

Li Gen motioned for the class to stand and applaud to see off the Guozijian people.

In the warm applause of the school, Li Gen and Kong Yingda saw off everyone in the country.

Guozi supervised the sacrificial wine, and mentioned that he would continue to send people tomorrow to come to the academy to learn about Tang Shu.

Li Gen naturally agreed.

"Commander, look at the sweet potato leaves picked by Wu Cao, they are all the freshest."

Wu Cao saw Li Gen coming out of the school, shook and ran over from the sweet potato field.

"You girl, you just like to eat sweet potato leaves, why isn't Lele with you? Have you ever completed your homework in the afternoon? ”

"Commander, grandpa and sister have been picked up!"

"A very handsome big brother picked it up!"

"My sister asked Wu Cao to tell the division commander that they will be back in a few days!"

"Wu Cao has finished the schoolwork left by the teacher, so come out and pick some sweet potato leaves!"

The little girl was looking up with her little head, and her big black and clear eyes were shining.

Li Gen smiled and nodded, and introduced to the people of Guozijian that this was the second daughter of Wu Shitong, the governor of Jingzhou.

When Dr. Guozi Jian heard this, he couldn't help but look at Wu Cao a few more times.

They still have heard of the reputation of the samurai.

"Zhuangyuanlang, can you really eat this sweet potato leaf?"

Everyone walked towards the gate of the manor, and Zhang Houyin, the priest of the country, asked curiously.

"Could it be that the sweet potato leaves around Chang'an City are not picked and eaten by the people?"

Li Gen was a little confused, this year's drought is so severe, and then there is a locust plague.

The entire Chang'an City is almost extinct, and because of this, the bean sprout industry in the manor has begun to operate again.

"No, the old man came all the way, and the pieces of sweet potato seedlings have never been heard of, and this sweet potato leaf is edible!"

Li Gen nodded rather annoyedly, with a pity expression on his face.

He is really to blame for this, and he didn't explain that the sweet potatoes are treasures all over his body.

Originally, I thought that Chu Mo would spread the word that sweet potato leaves were edible.

It seems that I am thinking too much.

This kid, who works confidentially, does a very good job.

Li Gen looked up at the sun in the west, and the sunset was full of red and fire!

"Seniors, it's still early before the curfew, so it's better to simply have dinner before leaving!"

"First, let the younger generations do their best to the friendship of the landlord, and second, let the seniors taste the taste of sweet potato leaves."

"Please also ask your seniors to inform Your Majesty at that time, let the people pick and eat, and the surplus can be exchanged for money in the market!"

After listening to Li Gen's words, Zhang Houyin, the priest of the country, happily agreed.

The second son is young, talented, and polite.

The future is immeasurable!

It is no wonder that Kong Yingda can value it so much.

"Wu Cao, tell Chunmei and Chunlan to fry a few more meat dishes, and give them these sweet potato leaves."

"Hmm."

Wu Cao happily carried the small bamboo basket and walked to the kitchen of the manor.

Guozijian and everyone followed Li Gen into the room.

While drinking tea, everyone asked Tang Shu about the origin.

Li Gen explained with a smile.

"The younger generation is also a whim, and they always feel that the current bookkeeping and calculation methods are too cumbersome."

"The Legend of the Fairy Tree"

"So I started to explore whether I could replace it with simple numbers."

"The younger generation, this is also for the sake of the saints! Although the younger generation was named Tang Shu, those multiplication and division methods are the crystallization of the painstaking efforts of the sages! ”

Li Gen's words made everyone nod with satisfaction.

Don't take credit, don't be proud!

The young man's good conduct has to make these literary heroes admire!

A rich fragrance is coming.

Zhang Houyin, the priest of the country, finally understood why Kong Yingda had grown so fat recently.

It turns out that the secret is here.

A plate of delicacies full of color and fragrance was served by Chunmei and Chunlan in turn.

Red Sleeves and Tian Xiang have not yet returned, in order to respond to the request of Chang'an City, the majority of diners.

Nowadays, restaurants are no longer serving diners at lunchtime.

Until half an hour before curfew, the restaurant serves diners throughout the day.

The benefit of this is that the income has skyrocketed.

Correspondingly, Zhao Si, Feng Wu and Red Sleeves, Tian Xiang, their pressure also doubled.

"Seniors, please eat."

"Your seniors still have to go to Your Majesty to restore your life, and the juniors won't pour wine for your seniors!"

Li Gen's thoughtfulness made Dr. Guozijian admire in his heart.

If you set foot in the palace with the smell of alcohol, even if Your Majesty doesn't say it to your face, you will feel disgusted in your heart.

Every delicious dish opened everyone's taste buds, and they abandoned the appearance of Sven's uprightness.

In front of a table of delicacies, the common face of human beings is revealed.

Stir-fried sweet potato leaves are really delicious and delicious, and the fresh taste makes everyone happy.

"Thank you for your hospitality, this is a feast for all the food. It's not too early, and the old man is leaving! ”

Zhang Houyin, the priest of the country, got up and said with a smile.

Li Gen sent everyone to the gate of the manor, and Kong Yingda also left with the doctors of the country!

Taiji Palace, in the Lizheng Palace.

Li Shimin and Empress Changsun spent the whole afternoon studying Tang Shu.

Just those few numbers, the two of them are very happy to study!

After dinner!

didn't even wait for the arrival of Dr. Guozijian.

Li Shimin frowned and spoke.

"These people must have stayed at the manor for dinner."

"Erlang, is this distressing for those pigs and sheep, or distressing for those vegetables!"

Empress Eldest Sun pursed her lips and snickered.

"I feel sorry for those pigs and sheep, but also for those vegetables."

"With so many people going together, how much do you have to eat?"

The more Li Shimin thought about it, the more painful it became!

Now I really regret that I let the prince of the country bring so many people to the wine.

Go to one or two, a doctor of arithmetic and a teaching assistant!

When Li Shimin was regretting it, the voice of the palace maid Yuzhi sounded at the door of the Lizheng Palace.

"Your Majesty, the queen mother, Zhang Xijiu begs to see!"

Li Shimin stood up when he heard this.

"Guanyin, I'll come to see you later."

Hearing this, Empress Eldest Sun smiled and nodded.

Li Shimin strode towards the outside of the Lizheng Palace.

Seeing that everyone in the Guozijian was outside the Lizheng Palace, eating one by one, the oil stains on their mouths had not been wiped clean.

"Follow me to the Imperial Study!"

Everyone followed Li Shimin into the imperial study.

Guozi priest wine Zhang Houyin spoke.

Li Shimin's expression immediately lit up.

"Your Majesty, Zhuangyuan Lang is really a genius!"

Li Shimin was very happy when he heard this, although he also knew that his eldest son was definitely a genius!

However, when these words came out of the mouth of the priest of the country, the meaning was very different.

Guozijian is the highest university in the Tang Dynasty!

According to the Guozi priest wine, in the hearts of literati and many young talents, the weight is still very heavy.

"Aiqing, tell me what you have gained from this trip carefully!"

Li Shimin took a sip of tea, put down the teacup, and said with a smile.

Guozi supervised the sacrificial wine, starting from Li Gen's first test question, and talked about it carefully!

…………

It wasn't until the people of Guozijian left the imperial study that Li Shimin learned from Li Delu that it was already three quarters of the hour.

Li Shimin was in the spirit of dragon and tiger, and went to the Lizheng Palace.

The eldest grandson queen had not yet fallen asleep, half lying on the bed, flipping through the books.

A delicate curve is perfectly presented in front of Li Shimin.

Li Shimin is an eagle and peels a chicken, and he will directly strike first!
