In the valley halfway up the northern slope of Longya Mountain, a row of bamboo houses are built directly on the stream, surrounded by thick shade and greenery, and the stream water flows under the bamboo houses, but there is no heat.

In the past few days, the weather on both sides of the Yuan River has suddenly become hot, and Han Qian has suddenly come to avoid the situation in Sizhou, regardless of the situation in Sizhou.

Wen Xin, who had just been a toddler, was running happily by the stream, and several guards and maids stared intently, for fear of an accident; Han Qian was idle during this time and began to supplement "Arithmetic".

Han Qian decided early on to compile books on arithmetic and diagram solving that were more in line with the rules of elementary mathematics on the basis of traditional arithmetic books such as the Nine Chapters of Arithmetic. Later, it was decided to derive the science of objects, empirical evidence and practicality on the basis of the "Book of Heavenly Craftsmen" compiled by Du Junyi and others, and form a special discipline for the more specialized and professional research and development of contemporary and later scholars.

These tasks sound simple, but in fact, they are extremely complicated and vast, and only Zhao Ting'er has the ability to assist Han Qian to complete them.

At present, it is promoted to the two-year elementary school at the county and township level, and the "Elementary Arithmetic" taught as a subject is written by Zhao Ting'er, but this is the most basic content in elementary mathematics.

Guo Rong had long heard that Han Daoxun, Han Qian's father and son had the strange book "Heavenly Craftsman Book" in their hands, but they only knew its name, not its shape.

Han Qian recruited him in Guanyue Tower in Qianyang City, and the only condition Guo Rong put forward was to see the true face of the "Book of Heavenly Craftsmen".

On the way to Quyang with Han Qian for inspection, Guo Rong's willingness was satisfied, and he saw the complete three volumes of "Heavenly Craftsman Book" that had been compiled so far.

However, after more than three months by Han Qian's side, Guo Rong really realized that the "Book of Heavenly Craftsmen" was still just a fur, and the real essence was derived from the "Book of Heavenly Craftsmen", such as calculus, diagrams, objects, empirical evidence and application.

A two-year primary school that teaches basic knowledge such as literacy and elementary arithmetic.

Usually, you only need to be proficient in reading and writing 1,000 words, as well as the basic four calculus and simple applications, to pass the course.

The higher-level calculus, diagram solving, lattice, and empirical application are taught in combination with the teaching practice of the State Medical Center, the Military Attache School, and the Engineering School.

All relevant matters are under the responsibility of the state school.

The compilation of textbooks is always rudimentary at first, and not only will there inevitably be errors and omissions, but also very superficial.

Guo Rong assisted Han Qian in acting state school affairs and was also responsible for the revision of textbooks.

Guo Rong prides himself on being brilliant and knowledgeable, but for more than three months, he has been trapped in many seemingly superficial existing teaching materials and has not been able to straighten them out.

At present, in addition to Han Qian, there are only a handful of people who can teach, such as Feng Yi, Zhao Ting'er, Du Qiniang, Ji Xiyao, Chen Jitang, and Du Junyi.

That is to say, these people, in addition to their own affairs, also have the affairs of compiling teaching materials and teaching, but at present everything can only be regarded as a rather simple prototype, and there is still a very long and difficult way to go before the system is complete.

Han Qian threw aside the manuscript of the supplemented "Arithmetic", stood in front of the window and stretched his waist to move his sore muscles, and listened to Feng Yuliang, Gao Shao, and Guo Rong walk in, and detailed the progress of Tan Yuliang's infiltration into Sizhou:

More than 100 prisoners fled to Yanying Peak, and Tan Ye persuaded Dong Tai, Zhang Guangdeng and others to do something together. They rested at Yanying Peak for the night, and went south from Yanying Peak in the early morning of the next day, and took the Shili Village located on the southeast slope of Panlong Ridge in the early morning of the next day; After resting for a day, after distributing the collected grain to the poor people in the village, the next day he rushed to cross Chenshui and attack Nanhuang Village before the Sizhou soldiers came to encircle and suppress it. They fought a tough battle in Nanhuangzhai, relying on the favorable terrain of Nanhuangzhai, repelled the first wave of Sizhou soldiers, killed and wounded more than 100 Sizhou soldiers, and beheaded Shi Shengjian and others, and the momentum was established. After that, according to the plan, he sent people to sneak to various townships and valleys at the eastern foot of Panlong Ridge, and called on slaves and maids and poor people to rebel with them. Dong Tai, Zhang Guangdeng and other prisoners themselves are fugitives or paupers in Sizhou, and they have a strong appeal in their respective townships, and in only three days, they gathered 2,000 people and horses in Nanhuang Village, which is so powerful that it can be said that they have not seen it for hundreds of years in this remote place of Sizhou......"

The purpose of making Tan Yuliang and Zhao Zhixian sneak into Sizhou is to knock on the mountain and shock the tiger, so that the princes and ministers above the court can throw rats and jealousy, and the persecution of Guangde Mansion is not so tight, but the slaves and maids and poor people are gathered to make trouble, and thousands of people are killed and injured at every turn, and the pressure on Han Qian's shoulders is not light.

Feng Yu reported in detail, and Han Qian asked a lot of detailed questions, asking Feng Yi and Gao Shao to continue to pay attention to the changes in the situation in Sizhou at any time.

Chen, Syria, Si, Ye and Qianzhong Prefecture have never been interrupted in wars for hundreds of years, but most of the wars are mainly fought for power and land by the big surname forces, coercing village slaves and civilians to participate in the war.

Slaves and commoners united to resist the oppression of the big caste forces, although they have not been interrupted for hundreds of years, but the scale is extremely limited.

There have been few truly influential, or memorable civilian uprisings that are feared and remembered by the big family forces, but there have been few in the past few centuries.

This is directly related to the relatively closed terrain of the counties in southwest Hunan Province.

This is not only the difficulty of connecting the prefectures and counties with the outside world, but also the extremely inconvenient transportation between the townships and villages in the prefectures and counties, and the contact between civilians and slaves between different townships and villages is very rare, and it is difficult to form the conditions for joint affairs.

Even the many villages directly controlled by the Yang clan have very little contact with each other's slaves and maids, and they are basically tied to the land where they have worked all their lives.

On the one hand, the prisoners rescued from the prison are all from all over Sizhou, and through the sale of smuggled salt and imprisonment, there is a relatively close relationship, on the one hand, Xuzhou has made a lot of preparations, secretly providing a lot of support, and another factor is the large-scale employment of Sizhou slaves and maids to work in Xuzhou, in just one year, not only in the hearts of the slaves and maids in Zhuzhai to smash the seeds of shackles, but also to promote the exchange and integration between them......

"Now the momentum is up, but out of 2,000 people, there are only five or six hundred young people who can fight. Although they could summon more people in the future, the Yang clan also reacted quickly at this time, and then stepped up the deployment of troops to gather on the periphery of Nanhuang Village. Tan Yuliang They want to effectively organize these young people in such a short time, but it is not an easy thing. Gao Shao frowned, and he didn't think that Tan Yuliang and the others had successfully taken the first step, and there would be no twists and turns in the situation in the future.

Han Qian also nodded worriedly.

Although Dong Tai, Zhang Guangdeng and others are currently pushing Tan Yuliang as the leader and setting up the banner of the Tianping Army, Tan Yuliang cannot act arbitrarily in all things.

The middle-level military attaches of the rebel army, in addition to Tan Xiuqun, Tan Qiu, Tan Lang, Tan Wenlin and other sons and nephews of the Tan family, are mainly Dong Tai, Zhang Guangdeng, Zhang Guangli, Dong Ping, Dong Qing and other salt lords who have a reputation in Sizhou.

After all, the vast majority of the rebel generals are still being co-opted by them.

As "friends of the rivers and lakes" that Tan Yuliang invited to help in the past, Diao Blind and other secret spies in Xuzhou were respected to a certain extent within the rebel army, but it was still difficult to directly command the generals who had a deep sense of identity and belonging to the village.

This is very different from when Han Qian established the command system of the Chishan Army, and he directly transferred and appointed people from Xuzhou.

This also means that it is difficult for the rebel army to overcome the shortcomings of the shortage of soldiers and the lack of training of the generals in a short period of time, and it is mainly supported by the blood and courage of the generals and high morale, but Tan Yuliang and their slightest carelessness at this time may suffer setbacks under the suppression of the well-trained and well-equipped Sizhou soldiers, and their morale may be severely damaged, and the situation will turn down.

This is a scene that Han Qian never wants to see, but Xuzhou cannot provide more direct support in a short period of time, and can only sit and watch the development of the situation for the time being.

"Yang Hu was ordered by Yang Xingfeng, the assassin of Sizhou, and just came out of Hujian Pass, and was rushing to Chenzhong County to see your lord." At this time, a fast horse galloped into the mountains from the boulevard, walked to the mountain stream and said in front of the bamboo house.

Although the Yang clan was not stupid enough to lure the wolf into the house, they directly asked Xuzhou to send troops to help suppress it at this time, but they didn't realize that everything was actually done by Xuzhou, and it was natural for them to send people over to ask for assistance from other aspects.

Yang Hunai is the second son of Yang Xingfeng, the assassin of Sizhou, who also leads the Jinhe county order, and Yang Shouyi, the general of Hujian Pass, is the principal of the eastern region of Sizhou.

Yang Hu personally rushed to Chenzhong County, Feng Yi guessed that Yang Xingfeng, the assassin of Sizhou, might have personally rushed to Jinhe County to sit in town, and said to Han Qian: "Why don't I go back to the county to deal with Yang Hu?" ”

"No," Han Qian shook his head and said, "Directly bring Yang Hu to the mountains to meet me." ”

Yang Hu first sent someone to Chenzhong County to report that he himself was on the way to Chenzhong County, and when he saw Han Qian say this, Feng Yu sent someone directly to the middle of the road to pick up Yang Hu into the mountain to see Han Qian.
