As a result, more and more Han chaebols and wealthy families began to invest in the construction of maritime fleets, and more private shipyards sprung up along the entire coast controlled by the Han Empire.

After noticing this phenomenon, Lü Bu asked Zhuge Liang, Fu Zhu, Jia Xu, Hua Xin and others to study a practical policy to strengthen management, and his principle was to encourage maritime trade, but resolutely crack down on smuggling.

He ordered the navy to set up a special coast guard unit, specially equipped with a small sailing boat of 200 tons with fast speed, which was responsible for coastal patrols, exterminating pirates, cracking down on smuggling, and all other illegal activities.

The Yellow Sea Fleet has also been expanded on a large scale, and Lu Bu instilled in the Han Navy that the navy is a hundred-year plan, a ten-year army, and a hundred-year navy, and the navy must persist in continuous growth and development in peacetime and maintain high-intensity and high-quality training.

In this way, when the navy needs to appear, it will be able to fight and win.

The Navy's Yellow Sea Fleet, which is responsible for foreign warfare, organizes one or two ocean-going exercises every quarter, going south to Jiaozhou, north to Siberia, and east to Japan.

The Marine Corps is also constantly expanding, after Wei Yan graduated from the Army University, he was sent to the Marine Corps by Lu Bu, and Lu Su took charge of daily training.

They will be given the opportunity to fight in the battle against the Japanese archipelago and the Korean Peninsula that have refused to trade with the Han Dynasty.

Of course, the most daily opportunity for actual combat is the battle of wits and courage with the Soochow naval army.

The Central Navy of the Han Dynasty set up a special detachment at the mouth of the Yangtze River, mainly with mine-sweeping units as the main force, and began to crack the mine array in the waters of Jianye, and now the speed of mine-sweeping has exceeded the speed of mine-laying by the Soochow Naval Army.

This is also thanks to the stupid method that Lu Su came up with, they cast some floating batteries, covered with armor plates on the outside, and installed eight-inch guns inside, which were arranged on the periphery of the mine array.

Once there are ships of Soochow to lay mines, they will be strongly bombarded by the battery, and the eight-inch artillery is enough to hit a distance of 800 zhang, even if Dongwu lays mines outside 800 zhang, but the Han army can also advance 800 zhang, right? This turret can be dragged.

If the Eastern Wu navy wanted to lay mines at night, then they had made a mistake, the Han army had already invented flares, these batteries could fire flares in turn at night, and if the Wu army dared to come, they would find that suddenly the surroundings were as bright as day.

At first, the Soochow Navy suffered a big loss, and then they could only occasionally steal a few mines at night, or simply lay mines outside the range of the fort during the day.

Although their ships in the middle of the Yangtze River were modified and installed with several guns, they did not yet have the technology to make eight-inch guns.

Therefore, they could not deal with the floating batteries of the Han army at all, so they were gradually encroached upon by the Han army, and at this speed, they could advance to the river outside Jianye City in a few days.

Moreover, the navy of the Han army was advancing from east to west, and the mine array of Hankou upstream had long been swept away by the Han army, and they had already advanced to the waters of Chaisang from the naval base in Exian.

Fortunately, Zhou Yu made arrangements before his death, built forts on both sides of the Yangtze River waterway in Chaisang, installed 20 six-inch guns, and set up mine arrays in the river, which restrained the advance of the Han army.

Unless they sent the army to capture the batteries on both sides first, they would not be able to clear mines with twenty guns.

However, this was only a temporary solution, and the Hankou shipyard of the Han army was building 500-ton galleons, and by that time, the broadside firepower of the galleons alone would be enough to deal with these shore batteries.

Therefore, Sun Quan, Zhang Zhao and others formulated a huge resettlement plan, sending a large number of Wu people and Wei refugees to Jiaozhou by land and Yizhou by water, and stepping up the development and construction of these two places.

Fortunately, Wu has always been rich, has a large amount of grain reserves, and rarely suffers from drought and locust plagues, which ensures the food supply of millions of Wei refugees.

Eastern Wu also began to learn from the successful experience of Wei and implemented the practice of all soldiers, but their population was not as large as that of Wei, and even so, the number of standing armies was insufficient, and in the hinterland of Yangzhou and Jiaozhou, and even Yizhou, there were a large number of Shanyue people and barbarians.

Therefore, although Eastern Wu occupies a vast area, there is a large number of people who do not obey the king, and the only advantage is that in the battle to suppress the Shanyue people and barbarians, the Wu army has gained a lot of actual combat experience.

Moreover, the situation is improving, the army of Eastern Wu is equipped with more and more firearms, and new officers trained by military academies are constantly joining the Wu army, and the combat effectiveness and training status are constantly improving.

Moreover, along with Cao Pi, there were also a large number of civil and military officials of the old Wei State, although the loyalty of these people has yet to be tested by time, but some not so important and fatal positions can still be safely appointed.

Sun Quan is the head of a country, and he still has the courage and courage to tolerate people, as the saying goes, don't use people who are suspicious, and don't doubt people.

Xun You, Xun Yu, Cheng Yu and others are all good at internal politics, and Cao Pi also has outstanding opinions when discussing politics in the imperial court.

As for Chen Gong, Le Jin, Cao Zhen and others, they also have real talents and practical knowledge in governing the army and fighting wars, and they can't be the chief general of the first army, and it is more than enough to be a deputy general.

Moreover, Sun Quan, Zhang Zhao, and Lü Meng also secretly spent effort to divide and disintegrate these civil and military ministers of the old Wei State.

They gave Cao Pi a high title and supported him, but never gave him the slightest real power.

Moreover, it is normal for the former ministers of Wei to be forbidden to communicate with him, and no one has any objections.

Sun Quan believed that as time went by, the relationship between the monarchs and ministers of Wei would only become weaker and weaker, and the efforts he spent to win people's hearts would definitely be rewarded.

Moreover, because Wu was far away from the battlefield in the Central Plains, since the Yellow Turban Rebellion, there were a large number of northern scholars and literati who moved south for refuge.

From Yangzhou to Jiaozhou, such northward migration celebrities abound, and since Sun Ce established the Wu State, he has always attached importance to talents, courtesy and virtuous corporals, and bought people's hearts.

Therefore, the talents of Wu State are endless, both civil and military, and because most of the people in Jiangnan have migrated from Jiangbei and have not yet formed a strong local clan force, some national policies and new policies can be implemented smoothly.

For example, the military service system, in which all the people are soldiers, has been promoted very smoothly.

Millions of Wei refugees had long since adapted to such a military service system, while the people of Wu, despite their small population, had developed a tenacious and warlike character in the long struggle against difficult circumstances and the South Vietnamese barbarians.
