Things like Liuli cannot be sold casually, as it is a crime to bear a treasure. If you sell too much, you may be killed.

I went to Chang'an to buy a bag of millet and carried it home.

Li Daxiong looked at his thin son carrying a bag of millet, "Where did you get the food?"

"I saved up the monthly money given by Hongwenguan and bought some food." Li Zheng casually made an excuse.

"I can't be hungry at home. It's great to have this money to keep for you to marry a wife." Li Daxiong was a little sad, but his son still felt warm with this kindness. The child became sensible and knew that he had saved money to buy food.

Li Zheng didn't want to tell him that he had sold Liuli to make money, and he was used to living a hard life, so he was afraid of scaring him.

Chang'an

Li Chunfeng came to Hongwen Pavilion again while he had nothing to do. He picked up the topic he had assigned before and thought that he would have gained nothing again today. He opened the bamboo slips he hung on him and looked at. This made Li Chunfeng stand in place for a long time and unable to move.

Looking at the crooked handwriting on it, the answer has been written on it!

Someone actually solved this question in the Nine Chapters of Mathematics. The Nine Chapters of Mathematics have been passed down for a long time and are being improved every time. The integration and compilation of several generations of people with great numbers has been achieved through generations of integration and compilation.

Every question in the Nine Chapters of Mathematics is the hard work of all the masters of the past dynasties, and cracking the Nine Chapters of Mathematics is also the threshold for the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters of the masters.

Li Chunfeng traveled throughout the Central Plains and believed that he had no rivals except Yuan Tiangang.

But now it seems...

Li Chunfeng's eyes were full of heat, and he called the head of Hongwenguan to ask, "Who is answering this book!"

"This..." The head of the company was so excited that he looked speechless for a long time.

"Find out the person! I will meet Your Majesty now." Li Chunfeng said that, and raised his foot and left.

Chang'an Palace Wude Hall

Li Chunfeng found the current emperor Li Shimin with a bamboo slip from Hongwenguan, "Your Majesty!"

Seeing Li Chunfeng coming, Li Shimin couldn't help but feel nervous when he saw his somewhat panicked expression, "What happened to Master Li?"

The Imperial Heaven Supervision has always been under the control of Li Chunfeng and Yuan Tiangang.

First, he gave a greeting and said, "Your Majesty! The nine-chapter mathematics question has been calculated!"

"What did you say?" Li Shimin was surprised. Li Chunfeng's math skills were also outstanding. The entire Tang Dynasty could have people who could solve nine chapters of math skills like Li Chunfeng. Apart from Yuan Tiangang, he had never seen anyone else.

Li Chunfeng talked about the reason, "I originally thought of putting this question in Hongwenguan, but I just wanted to try my luck, but I didn't expect it to be solved, and this person left an algorithm."

Asking the eunuch beside him to hand the thing to him, Li Shimin took the bamboo slip and wrote some words under the title that he couldn't understand, "This is..."

Li Chunfeng explained: "This kind of writing is also known in ancient books. This kind of writing was introduced to the Central Plains in Dashi back then. The writings written by this person are somewhat similar to those outside the pass."

"You mean the problem solved by people outside the Guanzhong." Thinking of this, Li Shimin became more confused and whispered: "But Hongwenguan is not like anyone outside Guanzhong."

"I think I am a person from Hongwenguan and can write characters outside the pass. This person only used a few lines of words to solve this question." Li Chunfeng bowed again and said, "Your Majesty, this person has extremely high numerical skills."

Li Shimin took a look at the question again. Mathematics are indeed very useful in some situations. If you abandon the geomantic astrology, you can also use mathematical techniques to marching and fighting, and then asked: "How long has Master Li been able to solve this question?"

"Your Majesty, this is what I have calculated." Li Chunfeng took out a distribution of silk again.

Li Er took the cloth silk and opened it and wrote dense words. Compared to the few lines before, Li Chunfeng solved the question and wrote the ten-foot-long cloth.

"Can you understand that person's solution?" Li Er asked again.

Li Chunfeng lowered his head a little lost, "I can't understand it. His words are like symbols, but this person can simplify the complex. This is a state of mind. Making the numerology and the numerology can be understood by one. If this person can be found, it can take the Tang Dynasty's numerology to a higher level and open up an unprecedented numerology method."

"Your Majesty!" The little eunuch came to report: "The Duke of Yiguo asked for a meeting."

Li Er nodded and signaled that someone would come in.

Qin Qiong walked into the Wude Hall and bowed to Li Er and said, "Your Majesty, the battle situation in Yinshan is resolved."

"What did you say?!" Li Er felt energetic. Li Jing had been confronting Jie Li Khan in Yinshan for several months, from last year to the point where there was no result yet. This is one of the things that made Li Er the most worried.

Qin Qiong handed over a bamboo slip and said, "This is a book from Hongwenguan. I will ask Hongwenguan to hand over all my insights on the war in Yinshan every day. Today, I saw a plan and asked Your Majesty to take a look."

Looking at the above content, Li Shimin understood it. This was a good idea to recommend the favor, and it was indeed a good idea. Why didn't he expect that the division of the feudal Zhishili and Ashina would use this to transform them and encircle Jie Li's troops.

After a closer look, the other party's policy discussion also mentioned the inconsistency between using Jie Li and Zhidu's thinking power.

Jie Li was already at the end of his journey. If it weren't for the natural danger of Yinshan, Li Jing would have taken him down long ago.

"This plan may work." Li Er nodded and said, "It's why the handwriting of the person who wrote the countermeasures is so unsightly and he still writes so many typos."

Thinking back again, Li Shimin whispered: "You can really give it a try, but how do the person who wrote this strategy knows that Jie Li and Zhi Di Si Li are incompatible."

Li Jing confronted Jie Li in Yinshan for several months and had been investigating the situation of the Turks. He was the best to take down Jie Li Khan of the Turks at the lowest cost. Even if he attacked for a strong attack, it was Li Jing's final plan.

Li Jing had already discovered the disagreement between Zhishi Sili and Jie Li, but this was a secret report, how could ordinary people know about this?

Looking at the paper submitted by Li Chunfeng and Qin Qiong, Li Shimin found two identical typos.

"You two will see if these two copies were written by the same person."

Qin Qiong and Li Chunfeng took the throwing paper and looked at the handwriting on it.

After a while, Li Chunfeng spoke, "Your Majesty, I have seen the words that are so bad, but this is the first time I have seen words that are so bad, even typos are the same, the same typos are written."

The handwriting is very poor, and the wrong words are written, Hongwenguan.

Li Shimin hurriedly said, "Investigate! Find out this person."

If you are only proficient in Nine Chapters arithmetic, you can be more optimistic, but even this person can know about the major issues of military and national affairs.

All the Hongwenguan volumes are managed by the Hongwenguan’s head. If someone writes a good strategy, the Hongwenguan will take them to submit them. The entire Hongwenguan is a tool for screening and collecting talents for Li Shimin.
