The Ryukyus had a good strategic location and natural resources, but it was indeed too remote for the Ming Dynasty in this era.

But Zhu Biao didn't think about using liuguan to manage Ryukyu.

In the previous life, after Zhu Di recovered Jiaozhi, he gained and lost in less than 20 years, and how many Ming soldiers died here.

It was a bloody lesson.

What is the reason?

Those low-ranking officials said that they went to the frontier to share the king's worries and educate the people outside.

But in fact, in such a place where the emperor is far away, it is impossible to do practical things, but it will make the strength of milk and make money ruthlessly.

In just a few years of office, these low-ranking officials who were sent to Jiaozhi all had the mentality that after this village, there would be no shop, and they were extremely corrupt.

They don't care that after they leave office in the future, the people's grievances will boil and the flood will be raging.

Human nature is selfish, and what is not one's own does not care at all.

Another example is Yunnan, where the situation was similar to that of Jiaozhi, but Lao Zhu let his son Mu Ying and his descendants guard Yunnan for generations.

For more than 200 years, the Mu family has been operating in Yunnan as solid.

After all, in the eyes of the Mu family, this Yunnan will be where they will live for generations.

For the Ryukyu Islands, Zhu Biaobei followed the example of some of them, and he would not be generous enough to let Wu Zhen guard the place for generations, but set the deadline for two generations, father and son.

Zhu Biao believed that this condition was enough for Wu Zhen to run the Ryukyu Islands with his heart, for himself and for his son.

After the two finished talking, Wu Zhen left with a look of anticipation on his face.

He also has a task, which is to make a statistics on the current coastal defense situation in various parts of the Ming Dynasty, and then report it to Zhu Biao.

Sure enough, once this person was promised benefits, the efficiency of this work was greatly improved.

However, in three days, Wu Zhen rushed to the East Palace and handed over the coastal defense information he had to Zhu Biao.

This general, although he also has his own thoughts, but compared with those literati, he doesn't have so many hearts.

From the information given by Wu Zhen, Zhu Biao also had a general understanding of the current coastal defense situation of the Ming Dynasty.

Due to the frequent harassment of the Japanese invaders, the Ming Dynasty began to strengthen the construction of maritime power, and several coastal counties in Fujian built 16 cities, increased the inspection department by 45, and killed more than 15,000 people.

That's a lot of money!

Zhu Biao couldn't help but sigh.

It is said that at the beginning of the Ming Dynasty, the treasury was empty, but look at the successive Northern Expeditions, coupled with such a huge investment in coastal defense, it did not drag down the imperial court, but the whole country was like the rising sun, a vibrant scene.

But in the middle and late Ming Dynasty, even if the world's silver flowed into the Ming Dynasty, the people were also prosperous, but the poor of the imperial court often could not pay military salaries, and the guards were also abandoned to a jaw-dropping extent.

It can only be said that there are not many corrupt officials in this era, and even if the amount of corruption is very small, it will not be lost in military salaries and materials.

On the other hand, it can only be said that Zhu Yuanzhang, the emperor, is really powerful, and later generations evaluate him as "the first emperor of eternity".

After Zhu Biao finished reading the coastal defense layout, he looked at the Ming warship that he was most concerned about.

Compared to the large steel ships he had seen in later generations, these wooden warships were indeed a little small, but they were more than enough to defend one side in this era.

In addition to the ships such as Lou Ship, Meng Chong, Fighting Ship, Sea Falcon, and Walking Boat that were available in the former Yuan, there were many innovative ships in the Ming Dynasty.

For example, an ultra-small net shuttle boat, shaped like a shuttle, with bamboo mast and wooden sails, has a draft of seven or eight inches, has 2-4 people inside, is equipped with two or three firearms, and two or three hundred boats are attached to the bees and ants during the war.

There is also a self-detonating truck model of the mother ship, the mother ship has firewood oil, gunpowder fire line, wartime mother ship quickly approached the enemy ship, nailed together, ignited the mother ship and the descendants returned by the sub ship.

Of course, there is also the main warship - the Daming Fu ship, which is as tall as a building, majestic, each of which is equipped with more than ten guns, as well as bowl-mouth guns, bird's beak guns, spray canisters and other large and small firearms, in addition, there are also several powerful bows and crossbows.

After all, firearms in this era are very afraid of water, and in case of a rainy day and the firearm fails, these powerful bows and crossbows are the last killer weapon.

In addition, there are many fleets of ships of all kinds, and they are all actual combat types, and there is no one in this world who can match them at present.

Zhu Biao watched it with relish, and shouted happily in his heart: Then let the annexation of Ryukyu become the first step in the expansion of the Ming Navy!

He was interested, and on the second day after reading the information, he couldn't wait to drag Fang Jin and Wu Zhen to the water division camp for a walk.

In the camp, when Zhu Biao was having lunch, he consciously asked Fang Jin and Wu Zhen to communicate more.

Although he himself has some understanding of the military, he only stays at the level of ordinary netizens, and if he points out indiscriminately, it will backfire.

However, Wu Zhen is worthy of his reputation as the Marquis of Jinghai, and he knows a lot about naval warfare, and he talks a lot.

Zhu Biao knew very well that although Fang Jin had military knowledge beyond this era, many times things that were too advanced were not good, and he first needed to understand and adapt to the characteristics of naval warfare in this era, and improve them on the basis of the original.

However, during the conversation, Wu Zhen would occasionally mention Li Shanchang and Hu Weiyong, obviously friendly with these two.

Zhu Biao remembered that after Hu Weiyong's outbreak in the future, although this guy had died of illness, he was still identified as Hu Dang, and the Marquis of Jinghai, who was inherited by his son, was dismissed.

He felt that in order to avoid Wu Zhen being involved in the future, it would be a good idea to let him guard the Ryukyus and stay away from the center of right and wrong.

In fact, Wu Zhen also has an elder brother named Wu Liang, who was named the Marquis of Jiangyin, and he is also a rare talent in water warfare.

Since the founding of the Ming Dynasty, there is no shortage of these talents.

Zhu Biao felt that he had to use it well and make the best use of his talents, but he couldn't waste it.

"Jinghai Hou, rest for a night, and tomorrow you take Gu and Lao Fang to board the boat together to have a look. Lonely, I've wanted to go to the sea for a long time. Zhu Biao smiled faintly.

He suddenly remembered something, turned his head and asked Fang Jin: "Old Fang, you always told me that the ocean is very important to Daming, what is that sentence called......

Your Highness, you are so benevolent!

Fang Jin knew that the crown prince wanted to make himself in the limelight, so he arched his hand and said: "Your Highness, that sentence says that if the country wants to be rich and strong, it must not ignore the sea, wealth is taken from the sea, and danger also comes from the ocean. ”

This is the famous saying of the navigator Zheng He, and it is also the earliest idea of sea power formed in history.

Wu Zhen muttered this sentence, and after repeating it, his eyes became brighter and brighter, and he felt that he hated to see each other late.

"Lao Fang, you have met a confidant." Zhu Biao deliberately patted Fang Jin's shoulder.
