One unfortunate thing after another.

Jiaozhou assassin Shi Yang Ji finally died because of miasma.

The so-called miasma is actually malaria, this thing was a big killer in ancient times, and the northern army went south, either infected with the epidemic or infected with this thing.

Yang Ji, like Huo Yi, is also a loyal and righteous person, in history was besieged by Tao Huang and Xue Jue hundreds of thousands of Wu troops, held on for eight months, no food and grass inside, no reinforcements outside, outnumbered, and finally surrendered to Wu, escorted Jianye on the way, depressed and vomited blood and died.

Before the funeral began, Liu Yin, a veteran of Hanzhong's Taishou, also died of illness due to his advanced age......

Yang Zheng looked back at Zhao Aqi and Liu Heng beside him, and suddenly found that their temples were also dyed white.

The crown prince Yang Xu has grown a beard, his bearing is becoming more and more calm, and he is handy in handling government affairs, and he has won the praise of the old ministers, and two months ago, Yang Chun, the grandson of the emperor, was born.

The years are unforgiving.

The old era is over, and the new one is coming.

In the past, when I rushed to kill on the battlefield, my body more or less fell into some disease roots, and every time it rained, my body was in pain.

Many generals were brave when they were young, and they fell ill when they were old.

"When people are old, they have to admit it!" Yang Zheng said with emotion.

Looking in the mirror, there are a lot of furrows on my face.

"Your Majesty, where is he old? According to the subordinates, there are still 300 more battles! Liu Heng said with a glare.

"Today, there are many people who are very prosperous, and it is rumored that they have elixirs to prolong life, why didn't Your Majesty summon them to inquire? Maybe there is a real ability. Zhao Aqi arched his hand.

"Those are all lies, the emperors of the past dynasties, how many of them can live a long life?" If you don't take the pill, you may be able to live for a few more years, and if you take the pill, you will hang up in two or three years.

Qin Shi Huang and Li Erdi both wanted to live a long life, but they both died early.

At present, the government affairs of the DPRK and China are managed by three provinces and six ministries, and the crown prince and several ordinary scholars are at the helm, and the country's operation is stable and stable.

Under their rule, Great Qin was in full swing.

Yang Zheng is happy.

In fact, he has a wish for a long time, but he can't retreat now, and the offensive of Hezhong and Annam still needs the support of his own emperor.

Time flies, and it has been five years since Taixing in the blink of an eye.

The agricultural scholars who went south finally found Champong rice, and successfully cultivated it in Jiaozhi, with a yield three percent higher than that of traditional rice, drought tolerance, strong adaptability, no picking of land, short growth cycle, and only more than 50 days from cultivation to harvest.

In Cochin, you can do three or four crops a year.

At present, it is being trialed in Lingnan, Yunnan, Jiangdong and Jingzhou.

However, a new problem is in front of Yang Zheng.

When the grain is grown, how it is transported to Guanzhong and the north.

Lingnan is mountainous, and walking from the mainland is not only time-consuming, but also labor-intensive.

Yang Zheng stared at the sand table, it seemed that he was going to develop shipping.

Since the establishment of the navy in the Spring Period and the Warring States Period, shipbuilding technology has been developing, and in the Eastern Han Dynasty, it was possible to build ten-zhang tall building ships.

When he arrived in Soochow, the Northern Expedition frequently stopped at Hefei, Sun Quan simply went south to open up the territory, occupied the treasure island first, and went south to the Philippines for a walk, feeling that it was barbaric and uncivilized, and walked back.

Soochow also built a five-story ship, five stories high, which could accommodate 3,000 people and could sail on the sea.

It's a pity that Cao Cao went south to attack Wu, Sun Quan got the fifth-floor boat into the Yangtze River, and in the event of a storm, Meng General Dong refused to abandon the ship to escape, stuck to the ship, and disappeared in the river with the fifth-floor boat.

In the first year of Jiahe (232 AD), Gongsun Yuan of Liaodong sent an envoy to Wu to claim the domain and offer horses, Sun Quan was overjoyed, and named Gongsun Yuan as the king of Yan, and at the same time sent 10,000 people to carry gold, silver and jewelry to escort Gongsun Yuan's envoy back to Liaodong by boat.

Being able to send 10,000 people to take the sea route shows that Soochow's navigation technology has been quite mature.

Yang Zheng has always felt that land power and sea power are like the two legs of the country, and one is indispensable.

In later generations, China's lack of sea power was the main reason for being blocked and besieged.

The current Great Qin, the land suitable for cultivation on the land, has basically been laid down.

However, there will always be a time when the land will run out, no matter how perfect the system established by Yang Zheng is now, as time goes by, there will always be various problems, and the new noble clan will definitely rise, and land annexation will definitely happen.

At some point, if there is no direction, it will inevitably repeat the mistakes of the Han Dynasty.

The ocean is the future of Daqin.

On the other side of the sea, there are corn, sweet potatoes, potatoes, and even more fertile land!

Injecting marine genes into Chinese civilization is also Yang Zheng's long-cherished wish and mission.

Maybe this process will take a hundred, five hundred years, but it can't be left out.

The occupation of Liaodong is 500 years ahead, and the operation of the ocean is 1,500 years ahead!

Of course, with the current environment in the country, it is still not appropriate to make a noise, otherwise the main peace faction will definitely think that Yang Zheng is going to conquer overseas again......

Yang Zheng could only set up a maritime department on the grounds of transporting grain by sea, under the jurisdiction of ship, sea and Wensancao.

The shipbuilding is responsible for shipbuilding, the sea is responsible for training seafarers, and the Wen Cao is responsible for the study of hydrology, weather, geography, positioning, etc.

Later, it grew stronger and was upgraded to the Ministry of the Sea, becoming the seventh of the six departments of the three provinces.

As long as there is no war, most of the courtiers do not care.

Importing grain from Lingnan, Jiangdong, Jianghuai, and Liaodong into Guanzhong was also one of the problems that Daqin urgently needed to solve.

Shipping can undoubtedly strengthen the control of Liaodong and Xiongjin.

Lingnan's cane sugar, pearls, and dried fish can also be transported by sea, from the Yangtze River into Jianye, from Jianye Shuoshui and Yingshui into Xuchang, and then from Luoshui to Luoyang, from the Yellow River to Guanzhong, or north to Yedu.

The whole of Great Qin is connected.

Sugar was present in the Zhou Dynasty, but it was boiled in wheat, and it was not until the Han Dynasty that sucrose appeared.

Of course, it is relatively rough, and it is basically made by boiling and filtering sugarcane juice, which is called "Zhe pulp".

The maritime and canal system is equivalent to the two veins of appointment and governor in China.

Hebei will be more closely linked with Jiangdong, and Jiangdong can also be closer to Lingnan!

The first step is always difficult.

There are not many people in Taixue who are familiar with maritime affairs.

When Wu was destroyed, nearly 10,000 craftsmen in Jianye City were recruited into the Ministry of Industry and stayed in Daxing, including a large number of shipbuilders.

Yang Zheng's rule is that before doing anything, make an outline and complete it on paper.

Therefore, first of all, let the craftsmen write down the skills of shipbuilding, compile it into the book "Ship Administration", and include it in the "Taixing Canon".

But it's also a huge undertaking.

I don't know if I don't see it, I was shocked when I saw it, in this era, there are not only building boats, but also various auxiliary boat types, everything in the sea and in the river.

"The more the better, the more detailed the better, the financial and manpower do not need to worry too much, you can try to improve the drawings and processes, if you have success, I will reward it!" Yang Zheng's ambition is not only to build a ship, but also to form a system and constantly upgrade and transform.

"Thank you, Your Majesty!" The craftsmen are overjoyed, in the country of Wu, how can they have this kind of treatment?

As soon as they entered Daxing, they were regarded as treasures, with 200 acres of fertile land per person, and the imperial court also set up two squares in Daxing, where every inch of land was valuable, and gave them their family rolls to live in, and they could collect rent every year, and they could live an incomparably nourishing life.
