Datang: Begin with Li Shimin as a father

Chapter 147 Listening to Jun's lesson is better than reading ten years of books
"Dean, the students have also figured out the answer!"

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

Wei Shuyu was quite unwilling to be robbed of the top spot by Yuchi Baoqi!
However, Li Gen's verbal praise made him sit down happily.

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

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

Li Gen smiled and nodded.

Soon, many young men figured out the answer.

Cheng Chuliang was the last one to get up and give Kong Yingda the answer.

Even so, this speed stunned the doctors of the Imperial College.

They would never believe that these young men are all arithmetic geniuses that are rare in a century!

"Principal Kong, please ask the seniors of the Imperial College to see if the calculation answers of the youths are correct!"

After listening to Li Gen's words, Kong Yingda nodded with a smile.

He took out the answers of the teenagers from the sleeves and distributed them to everyone in the Guozijian.

call!
call!
call!
Everyone was stunned.

Because the answers are all correct.

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

Everyone exchanged the answers of the students in disbelief, and it turned out that all [-] answers were the same.

The calculation method is quite different from the calculation method in Sun Tzu's calculation!
It is much simpler and more straightforward than the calculation method in Sun Tzu's arithmetic.

"Zhuangyuan Lang, today's trip really opened our eyes."

"Could this old man come up with a question to enliven the atmosphere of the school?"

Guozijian Doctor of Computing, stood up with a smile, and said.

"Senior, please come up with a question. It is the honor of the Zhuangyuan Academy to get the exam from the senior!"

Although Li Gen didn't know this person, since he was a doctor of Guozijian, he naturally had to treat him with courtesy!

After all, my own imperial examination was under the Imperial College, and the entrance exams for these teenagers were also completed in the Imperial College.

In terms of emotion and reason, Li Gen has a heart of gratitude to the Imperial College!
"Today there are chickens and rabbits in the same cage. There are 35 heads on the top and 94 feet on the bottom. May I ask how many chickens and rabbits are there?"

Guozijian Doctor of Computing, the voice fell to the ground.

Li Gen smiled and nodded.

Tell everyone, hurry up and solve the problem!
The teenagers held quill pens and began to count with their heads down.

The rustling sound of the tip of the pen touching the paper made everyone in the Imperial College feel ashamed.

It's no wonder that the young men are fast in calculation, and their writing speed has an advantage.

"Dean, I'm done!"

"Dean, the students are doing well too!"

This time Yuchi Baoqi and Wei Shuyu stood up almost at the same time.

Li Gen nodded with a smile, it seems that Yuchi Baoqi is quite talented in arithmetic.

The doctors of the Imperial College were stunned again!
That's it?
The speed is too fast!
Soon, all the young men submitted their answers.

The Guozijian Ph.D. in computing was stunned.

The answers on the fifty sheets of paper were all correct.

Chickens have twenty-three (23), rabbits have twelve (23).

Li Gen saw the real answer from the expression of the Ph.D.

That is, these teenagers have successfully answered all of them.

"Students, class is starting now. Today, because of the seniors of the Imperial College, I came to the college to guide the work. I will continue to unravel the mysteries of Tang Shu in the afternoon class."

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

Then start teaching!
.........

Everyone in the Imperial College, the more they listened, the more energetic they became, and the more they felt the variety and mystery of Tang Shu!
Because it requires a cumbersome number of word combinations.

If Tang numbers are used instead, it is just a matter of adding one or several numbers.

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

The teenagers in the school also listened with great interest.

Everyone has forgotten the time, and some are just the desire for knowledge, and the pleasure of solving the test questions.

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

"I'm going out today. I hope there are nine embankments, nine trees on the embankment, nine branches on the tree, nine nests on the branches, nine birds on the nest, nine chicks on the nests, nine feathers on the chicks, and nine colors on the feathers. How many are there?"

Li Gen said while writing with chalk on the blackboard.

Everyone in the Guozijian was stunned by such a topic.

It will take a long time for them to figure out the answer.

And Li Gen's calculation method is so fast that it is shocking!
"Students, this question looks too difficult, but it is very simple when calculated using Tang numbers!"

"Each embankment has nine trees, multiply nine by nine, and you get 81 trees."

Li Gen explained in Chinese and calculated on the blackboard with Tang numbers.

"There are nine branches of wood. Multiply 81 by nine to get 720 nine."

"A branch has nine nests. Multiply 720 nine by nine to get six thousand five hundred and sixty one."

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

"A bird has nine chicks. Multiply the 49 by nine to get 53."

"A chick has nine hairs, 53 ones, and then multiplied by nine, you get 440 nines!"

"Mao has nine colors. Multiply 4708 nines by nine to get the final answer, 960 ones."

Tang numbers on the blackboard are simple and clear!
Everyone in the Guozijian was completely convinced.

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

And the Tang numbers on the blackboard are used to calculate, it's that simple!
It's just a string of numbers!

Li Gen has been teaching this class.

One is out of respect for His Majesty, because everyone in Guozijian came here by order.

The second is to respect the seniors of Guozijian, who are all highly respected generations in the Tang Dynasty.

They didn't get up and leave, how could they have the nerve to finish class.

Until the sunset, Kong Yingda really felt sorry for Li Gen, so he touched the arm of Zhang Houyin, the sacrificial wine of the Imperial College, hard.

Zhang Houyin looked out the window, the sun was already going down.

Although I still have something to say, I had to get up and say goodbye.

"The number one scholar, listening to one lesson from you is better than reading ten years of books."

"I didn't expect that time passed so quickly, and Zhuangyuan Lang was troubled!"

"Senior's words are serious. The younger generation is young and healthy, so it doesn't feel hard."

Li Gen signaled the whole class to stand up, and applauded to see everyone in the Guozijian off.

Amid the warm applause from the school, Li Gen and Kong Yingda saw off everyone in the Imperial Academy.

Guozijian sacrificed wine and mentioned that tomorrow he would continue to send people to the academy to learn Tang Shu.

Li Gen naturally agreed.

"Teacher, look at the sweet potato leaves that Wu Zhao picked, they are all the freshest."

When Wu Zhao saw Li Gen coming out of the school, he staggered 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 finished your afternoon homework?"

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

"A very handsome big brother picked him up!"

"My sister asked Wu Zhao to tell the teacher that they will come back in a few days!"

"Wu Zhao has finished the homework left by the teacher, so I went out to pick some sweet potato leaves!"

The little girl raised her head, her big black eyes were shining brightly.

Li Gen nodded with a smile, and introduced to everyone in the Imperial College that she was the second daughter of the warrior Xun, the governor of Jingzhou.

Hearing this, the doctors of Guozijian couldn't help but look at Wu Zhao a few more times.

They had heard about the reputation of the warrior Xun.

"Zhuangyuanlang, are these sweet potato leaves really edible?"

Everyone walked towards the gate of the manor, and Zhang Houyin, the Imperial College's sacrificial wine, asked curiously.

"Could it be that no one picks and eats the sweet potato leaves around Chang'an City?"

Li Gen was a little confused. The drought was so severe this year, and the plague of locusts followed.

Vegetable production in the entire Chang'an City is almost extinct. Because of this, the bean sprouts industry in the manor has started to operate again.

"No, this old man has come all the way, and I have never heard anyone say that the sweet potato leaves are edible!"

Li Gen nodded rather annoyed, with a regretful expression on his face.

It was his fault that he didn't explain clearly that the whole body of sweet potatoes was full of treasures.

Originally thought that Chumo would spread the word that sweet potato leaves are edible.

It seems that I think too much.

This kid, keeping the job under wraps, did a really good job.

Li Gen raised his head to look at the sun in the west. At this time, the sky was full of sunset glow, and it was as red as fire!
"Seniors, it's still too early for the curfew time, why not simply eat dinner before leaving!"

"First, let the juniors do their best as landlords, and second, let the seniors taste the taste of sweet potato leaves."

"Seniors, please inform Your Majesty at that time, let the common people pick and eat, and the excess can be exchanged for money at the market!"

After hearing Li Gen's words, Zhang Houyin, the Imperial College's sacrificial wine, happily agreed.

The second son is young, talented and polite.

The future is immeasurable!

It's no wonder that Kong Yingda valued her so much.

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

"Ah."

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

Everyone in the Imperial College followed Li Gen into the room.

While drinking tea, everyone asked about Tang Shu's reason.

Li Gen explained with a smile.

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

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

"This junior is also learning for the sake of the past! Although this junior is named Tang Shu, those multiplication and division methods are the crystallization of painstaking efforts of the sages!"

Li Gen's words made everyone nod in relief.

No credit, no pride!
The upright character of the young man has to make these literary masters admire him!
A strong fragrance came.

Zhang Houyin, the Guozijian's sacrificial wine, finally understood why Kong Yingda had grown so fat recently.

It turns out that the secret is here.

Plates of delicacies with complete colors, flavors and flavors were served by Chunmei and Chunlan in turn.

Hongxiu and Tianxiang haven't returned yet, in order to respond to the request of the diners in Chang'an City.

Nowadays, restaurants no longer accept diners during lunch time.

Until half an hour before the curfew, the restaurant entertains diners all day.

The advantage of this is that the income has skyrocketed.

Correspondingly, the pressure on Zhao Si, Feng Wu, Hong Xiu and Tian Xiang doubled.

"Seniors, please eat."

"Seniors have to report back to His Majesty, and this junior will not pour wine for you seniors!"

Li Gen's thoughtfulness made all the doctors of the Imperial Academy admire him.

If he stepped into the palace reeking of alcohol, His Majesty would feel disgusted even if he didn't tell her face to face.

Every delicious dish opened up the taste buds of everyone, and they all abandoned the appearance of being gentle and correct.

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

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

"Thank you, Zhuangyuan Lang, for your kind hospitality. Such delicious food is really a feast for the mouth. It's getting late, and I will bid farewell!"

Guozijian Jijiu Zhang Houyin 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 Imperial College!
Tai Chi Palace, Lizheng Hall.

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

As far as those few figures are concerned, the two of them had a great time researching!

After dinner!

He hadn't even waited for the arrival of a doctor from the Imperial College.

Li Shimin frowned and said.

"This group of people must have stayed in the manor for dinner."

"Erlang, do you feel sorry for those pigs and sheep, or do you feel sorry for those vegetables!"

Empress Changsun pursed her lips and snickered.

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

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

The more Li Shimin thought about it, the more his heart ached!

Now I really regret that I let Guozijian sacrifice wine to bring so many people there.

Just one or two, a doctorate in computing and a teaching assistant will do!

When Li Shimin was regretting endlessly, the voice of the court lady Yuzhi sounded at the gate of the Lizheng Hall.

"Your Majesty, Empress, please see Zhang Jijiu!"

Li Shimin stood up upon hearing this.

"Guanyin maidservant, I will come to see you later."

Upon hearing this, Empress Changsun smiled and nodded.

Li Shimin strode out of the Lizheng Hall.

I saw that everyone in the Imperial College was outside the Lizheng Hall, eating one by one, and 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.

Zhang Houyin, the Guozijian sacrificial wine, opened his mouth.

Li Shimin's expression immediately brightened.

"Your Majesty, the number one scholar is truly a genius!"

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

However, when these words came out of Guozijian Jijiu's mouth, the meaning was quite different.

Guozijian is the highest school in the Tang Dynasty!
The words of Guozijian Jijiu are still very important in the hearts of literati and many young talents.

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

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

Guozijian sacrificed wine, starting from Li Gen's first test question, and carefully explained it!

…………

It wasn't until the Guozijian people left the imperial study that Li Shimin learned from Li Delu that it was already the third quarter of Haishi.

Li Shimin went to the Lizheng Hall in a spirit of dragon and tiger.

Empress Changsun hadn't fallen asleep yet, half lying on the bed, flipping through books.

An exquisite curve, perfectly presented in front of Li Shimin.

Li Shimin is an eagle peeling chickens, so he will strike first!
