The trial planting of Champong rice in Jiaozhi and Lingnan has been quite successful.

In fact, Yang Zheng was not sure whether this thing was the Champa rice discovered in the Song Dynasty hundreds of years later.

But as long as the yield is higher than the current rice seed, it is successful.

The fertility of the Red River Plain is by no means a lie, since the Han and Wei dynasties, it has been developed and operated by the industrious Chinese people for hundreds of years, and it has long been a mature plate, and has been supporting the Eastern Wu.

Three or four harvests a year, the horror of grain production can be imagined.

With food, coupled with the relaxed environment of Daqin's inaction, there was a wave of outbreaks in the local population.

Mao Jiong's reply letter not only thanked Yang Zheng for his reward and trust, but also gave a detailed introduction to the governance achievements in recent years.

Kaixian 12, along the Red River upstream to expand the land 1,500 miles.

The population increased by 270,000, of which 110,000 were native slaves and the other 160,000 were children born in recent years.

Guangzhou Tao Huang is also on the table, because the grain production has tripled, Guangzhou's population has also seen explosive growth, with an additional population of 170,000.

Guangzhou's population has not increased as much as Jiaozhou, which surprised Yang Zheng.

But when you think about it deeply, it makes sense.

Since the Han and Wei dynasties, the importance of Jiaozhi is actually still above Lingnan.

There are many mountains in Lingnan, and there are many in Nanban and Shanyue, and they rob and rebel at every turn, which seriously restricts the development of Guangzhou.

The Red River Plain has a dense water network, which is vast and flat, which is more suitable for development.

Yang Zheng remembered that in history, Guangzhou really developed in the Tang Dynasty, not because of agriculture, but because of the rise of commerce, and a large number of Arab merchants came to trade in the Central Plains by boat.

Later, Huangchao rebelled and moved to Lingnan, slaughtering 200,000 Hu merchants in Guangzhou at one time......

Jiaozhi is not only a granary for Huaxia, but also a strategic land, and the loss of this land is an eternal pain for Huaxia.

But this pot is about to be thrown to the Great Cowardly Dynasty......

The Ming Dynasty wanted to recover, but the local area had already risen its own ethnic consciousness, and there were a lot of things in the Ming Dynasty, so they gradually gave up this fertile land.

As the population increases, Hermes-Epitek naturally increases its control over the local area.

"I want to establish Jinlan Kingdom in southern Xinjiang, why does Bo Yu think so?" Yang Zheng has long had this thought.

Cam Ranh Kingdom, that is, the area of Cam Ranh Bay in later generations, how perfect this place is, needless to say.

As long as future generations are a little more competitive, this place will become the core area of Chinese civilization that radiates to the South Seas.

"In a reckless land, it doesn't hurt to establish a country, but Jiaozhi must not be divided and sealed." Wei Zheng's views basically represent the thoughts of the vast majority of the elders in the DPRK, and Wei Zheng generally will not disobey Yang Zheng's opinions.

"What Boyu said is very true!" Cam Ranh plus Jiaozhi is enough to become a country of its own, and Cam Ranh will lose its pioneering spirit and lie flat on the rich Red River Plain.

Divide your own heirs and bloom everywhere, so as not to be able to do it in a few hundred years, Daqin will not be able to do it and be served by others.

At the court meeting three days later, Yang Zheng proposed the plan to establish a country, and sure enough, no one objected.

Everyone's mind is on the Western Regions.

Half of the people were not afraid that the Western Regions would be lost, but that Yang Zheng would continue to bet and consume the strength of Great Qin......

When the Qiang people were in rebellion, in the Eastern Han Dynasty, some people even suggested that even Liangzhou should not be wanted......

The Sassanids defeated Yin Chun and Yang Yi, and the countries of the Western Regions began to turn, and no one wanted to be pinched by others.

Of course, the Sassanids were also intimidated by the might of the Qin army, and the 50,000 troops were overturned on their backs by 17,000 soldiers, suffering heavy casualties, which also made them re-examine the rise of this powerful empire.

Start looking for new allies.

Kangju and Dawan, who originally said that they would surrender to Daqin, completely fell to Sasan, made a detailed report, and also set an offensive and defensive alliance to resist the brutal and evil Daqin together......

The countries of the Western Regions were originally grass on the wall, and Yang Zheng didn't have much hope.

Now they are turning to the Sassanids, and they are all together.

Judging from the sand table, the seven river basins of Xia Kingdom are a little far away from the river, and Dawan Kingdom is just sandwiched in the middle.

The Fergana Basin, west of the Green Ridge, is the upper reaches of the river, which is condescending, easy to defend and difficult to attack, and can be described as a strategic place.

In a word, if you want to eat the river completely, you must take Dawan!

In fact, Emperor Wu of the Han Dynasty also had this heart, but unfortunately he entrusted it to no one, and sent his brother-in-law Li Guangli, the general of the second division, to conquer, but it is a pity that this generation of brother-in-law is not as good as the brother-in-law Wei Qing of the previous generation, and the loss of troops and generals, the record is mediocre.

"There is no need to worry about the affairs of the Western Regions, Du Yuankai is a genius in the world, and Ma Xun and Tian Zhang are the generals of the bear and tiger, and they will definitely defeat the enemy!" Yang Zheng said confidently.

The wind knows the strength of the grass, and the board swings to see the loyal ministers.

Great Qin still has a few staunch dogs in the Western Regions, Khotan, Loulan, Shule, etc., Yang Yi's Xia Kingdom in the north, Gaochang and Dunhuang in the east, and a large number of Xuanyi envoys and Jinyi Guards in various countries, and Daqin is still a giant in the Western Regions.

The affairs of the Kingdom of Jinlan are unimpeded.

With Lao Jiu Yang Yu as the king of Jinlan, he led 1,000 Qingying children, 2,000 soldiers and more than 10,000 people with their families to the south.

Yang Yu is the most honest of several sons, and he is low-key.

Like his mother, Jiang Alian, there are many Qiang Qin people in the department.

However, low-key is low-key, coming out of the Qingying, both civil and military are the basic requirements, and what Yang Zheng values is his character.

The son who is too crazy and jumpy, but it is not suitable for sealing out.

Maybe one day when your mind is hot, you will come back with a knife......

Yang Zheng also accompanied more than 100 medical scholars to the south to concentrate on tackling malaria.

Malaria is indeed tricky, but it is not a terminal disease, there have been people studying it in the pre-Qin era, there has been a detailed record in the "Yellow Emperor's Neijing", and the "Shennong's Materia Medica" collected and sorted out into a book in the Eastern Han Dynasty clearly records that the plant Changshan has the effect of curing malaria.

The medical saint Zhang Zhongjing's "Treatise on Typhoid Fever and Miscellaneous Diseases" also has many prescriptions for treatment.

If you want to run southern Xinjiang, the first thing to solve is the miasma, not to seek a complete cure, as long as it can be alleviated and prevented, it can greatly improve Daqin's control over the local area.

"As long as you solve this evil disease, I will reward it with the Marquis!" Yang Zheng patted his thigh and said.

The medical scientists' eyes widened as if they couldn't believe it.

No wonder they have such expressions.

Qin Hanli made military achievements and became a marquis, and now he can also be a marquis for treatment, and he can't think about it.

But Yang Zheng felt that the improvement of medical care could greatly improve the health of the Qin people, and they were not only more energetic in farming, but also had the strength to go out and cut people......

In all dynasties, the number of people who died from disease was far greater than on the battlefield.

A plague can wipe out a race.

The great plague at the end of the Han Dynasty, to this day, still often shows its fangs.

From this point of view, these medical scholars are also warriors, but their enemies are diseases, so it is better to give them a marquis than to fight on the battlefield.

"Why, you don't want to be a marquis?" Yang Zheng joked.

Everyone was shocked, and immediately their eyes erupted with ecstasy, "The ministers will overcome the miasma!" ”
