In the thirtieth year of China (242), China conducted the fifth census, and the population of Chinese population had reached 100 million.

Zhang Yi is very satisfied with looking at the territory he has conquered over the years, East Asia, Southeast Asia, Australia, and has extended his tentacles to South Asia.

He is almost seventy years old this year, but his body is still strong, and just last year he had his fortieth son with his eighteenth concubine.

Zhang Yi felt that he could live a long longer, although many of the old ministers who founded the country with him were old, and many of them had even passed away.

Lu Su, Zhu Zhi and other important ministers died one after another, Li Hongzhang, Fan Zhongyan and others retired due to illness, and the current prime minister is Zhuge Liang, who is already sixty years old.

Zhuge Liang did not show much talent in military affairs in this life, and there were only a handful of people with the army at this time, and the time when he led the troops was in Yongzhou and Sizhou.

But his talent for invention was very much on display, as long as he had nothing to do, he would take his wife Huang out of the fields or workshops, and invented many more advanced farm tools and war supplies.

Together with Ma Jun, he once again improved the trebuchet, turning the trebuchet into a packed trebuchet that was easy to transport (refer to the packing trebuchet in Age of Empires 2), and with this siege weapon, Zhang Yi's army was invincible.

In fact, there are not many places that can allow Zhang Yijun to attack, and when the packing trebuchet is used in large quantities, it is still attacking the Great Food Country (India).

For more than ten years, Zhang Yi has almost stabilized Southeast Asia, and many Southeast Asian products have been sent to the Central Plains, and the Central Plains are also constantly immigrating overseas. The land in the Central Plains is limited, and Zhang Yi also needs people to cultivate land overseas.

So Zhang Yi directly gave the title of Lang official to anyone who explored overseas, regardless of gender. In the Central Plains, where the practice of martial arts is gradually recovering, many women follow the example of many of Zhang Yi's daughters, especially Hong'er.

Although Hong'er has become a mother after marrying Lu Xun, she often goes on expeditions with Lu Xun. Not only does he know how to boost morale, but he can even command battles.

It is often said that there are two whole people among the royal heirs, one is the eldest prince Zhang Xingren, who is omnipotent in marching and fighting to govern the country, and has become a deputy minister after decades of hard work. The other is Hong'er, who has fought with the army many times, inspected places many times, and dealt with many unjust, false and wrongful cases, and punished dozens of corrupt officials and corrupt officials, each time it is fair and open, which is convincing.

Zhang Yi is also happy to use Hong'er as a role model to improve the status of women. Although he had many wives, he was very happy to elevate the status of women.

Now that the population of the country is small, there will be many vacancies in the labor force with men alone, which can only be filled by women. Zhang Yi even opened up the system of women as officials, and formed women's armies in various places to replace the army and take on security tasks with retired veterans, so that these soldiers could be transferred to places where they were needed more.

After the stabilization of Southeast Asia, Zhang Yi also began the strategy of the Maritime Silk Road. He set up Southeast Asia into several major regions, and together with Australia, he set up the Southern Regions Metropolitan Protectorate, the Southern Central Metropolitan Protectorate, the Southern Eastern Metropolitan Protectorate, and the Southern Western Metropolitan Protectorate.

Each of the four prefectures was headed by a prince in the prime of life, who was elected between the ages of 30 and 40 and served for a five-year term. This was to prevent some of the princes from becoming ambitious and establishing themselves as kings.

Zhang Yi wanted an enemy country with a huge territory, not a world of Han Chinese who fought each other.

After the establishment of the four major capitals, the Han Chinese fleet had already crossed the Great Food and engaged in maritime trade with the newly restored Persian Empire. Every ship that is unsinkable will gain tens of millions of riches.

This is also the result of Zhang Yi's encouragement of risk-taking, because wealth and wealth are in danger, and powerful merchants have begun to develop in the coastal areas, wanting to get a piece of the emerging Maritime Silk Road.

As a result, three economic belts have emerged in China, one is the Yizhou, Yongzhou, and Liangzhou economic belts in the west, which rely on the Silk Road. One is the Maritime Silk Road Economic Belt to Southeast Asia through the coastal gaze. The last one is the river, canal, and river economic belt.

Speaking of canals, I have to say that Zhang Yi successively let his son-in-law serve as the chief officer of digging the canal and expanding the river.

By the time of the 30th year of China, the canal had been connected from the area of Jixian County, Youzhou. As the northern end of the canal, Jixian County has also gradually developed, and with the seaport of Quanzhou (Tianjin area), the Jiquan area has become the richest area in Youzhou.

With the development of Jiquan, China has gradually formed six large economic zones. The economic zone centered on Shouchun, the economic zone centered on Shanghai Port, the economic zone centered on Panyu, the economic zone centered on Chang'an, the economic zone centered on Jiquan, and the economic zone centered on Qingzhou.

The development of the Maritime Silk Road made the big cannibals very dissatisfied, because Chinese merchants went from here and did not pay taxes at all. This was intolerable to them, and in order to avoid paying taxes, these Chinese merchants did not even stop at their ports, but occupied nearby islands as their own strongholds, and then hired big cannibals as agents for smuggling.

Seeing hundreds of millions or even billions of wealth slipping away from his eyes every year, how could Da Shi endure it? So he gathered a large number of sea ships and attacked the stronghold of Chinese merchants on Heather Island (Sri Lanka, originally called Shinan Island, but later became Heather Island after shouting).

The Chinese merchants on Heather were not bad in force, and although they did not have the most advanced weapons in the army, they did have many bows and crossbows that had been eliminated from the army. For example, the most primitive ballista and the repeater developed by Zhuge Liang at the beginning.

These weapons were sold to overseas caravans, which made the government a lot of money. All this money is used to subsidize military spending and invest in the research and development of new weapons.

The attack of the Great Food Kingdom made the Chinese merchants very angry, and the merchants found Jiang Wei, the assassin in Xizhou, and expressed their desire to attack the Great Food Country.

Jiang Wei, as Zhang Yi's son-in-law, has the power to make decisions on the spot. As soon as he heard that his merchants were attacked, he immediately led his troops to attack westward, crossed the Ganges River from Xihai County, and began to conquer the Great Food Country.

In the face of China's army, armed to the teeth, the Great Food Country was simply unable to resist. In less than six months, Jiang Wei completely occupied the entire Ganges River basin.

In the thirty-first year of China, Zhang Yi heard about this, and asked Deng Ai and others to lead an army of 50,000 to continue to conquer the Great Food Country.

In June of the 32nd year of China, the Great Food Kingdom was destroyed. Zhang Yi set up Nanzhou here, with Deng Ai as the assassin of Nanzhou, and led the military and government here.

The Great Food Country has a population of no less than one million, and is gradually recruited as a laborer by the Han Chinese. The fertile area was soon occupied by the Han Chinese, becoming one of the granaries of China.
