The current Tang Dynasty Li Shimin dominates the East, which can be regarded as the sky.

However, due to population and transportation constraints, there was no energy to continue to expand in a short period of time, and even Situ Changfeng's war in Tianzhu was dominated by ethnic minority fighters.

20,000 Khitan iron horsemen, 50,000 Turks led by Qikebi to kill from the Tubo County Plateau, 30,000 Miao people, 10,000 Dong people, also came to Tianzhu, these are the local minorities of the Tang Dynasty.

As more and more people entered Tianzhu, the process of conquest was accelerated, and in the seventeenth year of Zhenguan, the king of the day led 600,000 people to flee into Guishan, and the entire Tianzhu fell into the territory of the Tang Dynasty, and the territory of the Tang Dynasty expanded by fifty percent.

After the occupation of the Tang Dynasty, Li Shimin set Tianzhu as Tianzhu Prefecture, divided into ten counties, appointed Li Tai as the pastor of Tianzhu Prefecture, and at the same time crowned Situ Changfeng as the founding Yizhou County Prince, Shangzhu State, Yipin Zhengxi General, Tianzhu Metropolitan Governor, fully responsible for the development of Tianzhu.

Of course, Li Shimin could not let Situ Changfeng's family dominate, Li Yuanba, the king of Zhao, heard that there was a war to fight, and there was no threat in the country, he also came to Tianzhu and was responsible for leading an army of 200,000 to guard the border passes.

At the same time, Li Jing was appointed as the governor of the Western Regions, forming a two-sided attack on Guishan, but he would not take the initiative to send troops in the past two years.

Because the Xiongnu fled far away, the Qin Wangfu was also liberated, and the northeast area, the four counties of Liaodong, were all guarded by their manpower.

Shandong, the Guanzhong family, stationed in Wadao, the Jiangnan family went south, and divided Southeast Asia with the Sun family.

Of course, Li Shimin will not make the previous mistake, the family divides the territory, but there is no military force.

Only the Sun family, the strength of the Qin Wangfu is still the same, but in order to show their loyalty, both families chose to send their sons to Beijing, and not one, even the generals under them sent a few.

Because Li Shimin gave the people and the soldiers concubines and wives, plus preferential treatment, it can be said that he is extremely loyal to Li Shimin, which is also Li Shimin's confidence.

At the same time, according to Situ Changfeng's suggestion, the Tang Dynasty investigated and banned most of the Taoist temples and temples, and only some famous mountains remained.

Some Taoist monks were forced to be vulgar, while others went to various places to promote patriotic education.

People make the best use of it, Li Shimin never thought that people could use it like this, by the imperial doctor and people with superb folk medical skills, plus Taoist monks who are proficient in the art of Qihuang, the establishment of a medical school, and the division of internal medicine and surgery, gynecology and pediatrics, the establishment of hospitals in various places, and the control of the imperial court, so as to avoid some people with bad character in various places, indiscriminate charges. Not only that, but medicinal material bases are also being established.

All industries, standardization, and customized standards, industry requirements, this is the new trend of the imperial court, for which the top people in various industries are also invited to participate.

Situ Changfeng closed the door and carefully recalled some good policies in later generations, and wanted to try his best to help Datang go further, because with the current national strength, it has reached the limit.

It doesn't make much sense to continue to conquer other places, first, it's too far, and secondly, the rest of the people, and the Han people, the appearance is too different, and it's too difficult to want them to integrate completely, unless Datang has the strength to crush them, let them take the initiative to integrate. Just like the motherland of later generations, countless small countries hate to be born under the red flag.

Therefore, Situ Changfeng urgently suggested that Li Shimin bring together elites from various industries, which can not only make the industry bigger and stronger, but also accelerate the development of the industry and bring forth the new.

For this reason, whether it is the Tianzhu people, or the people of the Western Regions, or even the Nanyang Tu people, as long as they have a skill, they are all reused.

The latest Ministry of Industry, established outside Chang'an City, covers an area of hundreds of acres, like a small city, the craftsmen, craftsmen and their families in the Ministry of Industry, reached more than 20,000 people. This is still a highly skilled, or a talent with special skills, and other poor people can't enter the Ministry of Engineering.

The three provinces and six ministries have long been unrecognizable, commerce, law, staff, medical care, transportation, marine, agriculture, administration, supervision, industry, minerals, and dozens of departments are all designed in Longshouyuan, outside Chang'an City.

The new palace of Longshouyuan is also under construction, but the expansion of the Tang Dynasty is too fast, and Chang'an City, which originally felt very big, is no longer enough.

In the eighteenth year of Zhenguan, the fleet of the ocean-going Great Qin returned to the Tang Dynasty, bringing news from afar, as well as nautical charts.

In the same year, a larger warship was launched, the new warship was 500 meters long, with an alloy shell, lighter, stronger, the ship was divided into four layers, up to 15 meters, and a ship was full of 10,000 people.

The layered vessel is able to ensure that the bottom two floors are flooded and can continue sailing.

In the second year, Situ Changfeng, who couldn't stand the loneliness, took his eldest wife Zheng Liwan, Princess Yuzhang and Gongsun Feiyan to ask him to go to sea, leaving only Fan Lihua at home with the children.

In recent years, the second generation of the Tang Dynasty has fully grown up, and Su Dingfang is sitting in the Western Regions; Cheng Chumo, Yu Chi Baolin, Qin Huaiyu, and Li Xiaoyi sat in Wadao; Tianzhu also has Li Tai, Li Chonghui, Luo Tong, Luo Huan; The Tubo Plateau was guarded by Xue Rengui.

In the center of the Tang Dynasty, Xi Jun bought the new Chang'an Order, and Di Renjie served as the squire of the Criminal Department.

In February of the twentieth year of Zhenguan, Luoyang Qu Tutong died of illness; In September of the same year, the left servant shot Xiao Yu and died.

In June of the twenty-first year of Zhenguan, the right servant shot Du Ruhui and died, and Qin Qiong died of illness in September.

After losing his ministers one after another, Li Shimin was very sad, but fortunately, Situ Changfeng returned from afar, bringing great news.

This time, it took two and a half years for Situ Changfeng to travel to the Americas and bring back sweet potatoes and corn seeds.

When the freshly ripened corn was brought down from the ship, the chopstick-long grain stunned the court up and down, not to mention the fist-sized sweet potato.

Although these grains have not been cultivated by grain seeds, they can be much higher than wheat yields.

Now everyone is very confident in Situ Changfeng, so Li Shimin did not hesitate to order the promotion. He seems to have anticipated the scene of Datang without famine.

In the twenty-second year of Zhenguan, Li Jing, the secretary of the Ministry of War, said goodbye to the old, and Li Shimin did not choose Hou Junji and others, who were more qualified, but appointed Situ Changfeng as the new secretary of the Ministry of War.

As the older generation gets older, there are many people who die and return to their hometowns. At present, the left servant shoots Fang Xuanling, and the servant shoots the eldest grandson Wuji, the secretary of the military department Situ Changfeng, the secretary of the household department Li Ji, and the secretary of the Ministry of Works, Hou Junji and others are regarded as a group of people with the highest status in the center.

Zhenguan twenty-three years, sweet potato, corn harvest, should have been the day of celebration of the whole world, the queen eldest grandson died of illness, nicknamed Empress Wende, buried in Zhaoling.

Carefully calculated, in fact, many people have prevaricated the time of death compared to Situ Changfeng's world, which should be related to the higher strength of this heaven and earth.

In the twenty-fourth year of Zhenguan, because of the bumper harvest of grain year after year, Li Shimin couldn't bear it, and left the crown prince Li Chengqian to supervise the country, and took the veteran generals of the court and China to conquer Guishuang in person.
