At this time, Japan's handicraft industry was underdeveloped, and many daily necessities such as silk, cloth, pots, needles and medicinal materials were supplied by China, once when China lacked goods, the price rose sharply, such as silk was worth five or six taels of silver per 100 catties, and in Japan its price was more than ten or twenty times that of China, so the huge profits naturally made people excited.

After the founding of the Ming Dynasty, there were still remnants of southern forces such as Zhang Shicheng and coastal smugglers who cooperated with Japanese pirates and used some Japanese islands as bases to continuously harass the coasts of China and Korea, which was also a reason for stimulating the sea ban in the early Ming Dynasty.

After Zhu Yuanzhang founded the country, he also sent envoys to Japan in succession to restore relations between the two countries, and wanted the Japanese king to restrain his subordinates, but because Japan was in a state of division and confrontation, not only did he send envoys several times to no avail, but the invasion of the Japanese invaders became more and more complicated.

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

Zhu Biao also learned from the Marquis of Jinghai that in the second year of Hongwu, the Japanese invaded Shandong, Suzhou, Huai'an, and other places on a large scale, and that year was tragic at any time, and the coastal towns were all hit hard.

Last year, there was another serious invasion of the Japanese invaders on the coastal areas of Shandong, then plundered the Ming, Taiwan, and Wen prefectures in Zhejiang, and then plundered the coastal counties and counties of Fujian.

Now it's a new year, and the Ming army has learned that the Japanese who are wandering near the Ryukyu Islands are preparing to plunder again, and the Ming army has carefully deployed their defenses according to Tang He's order.

After a group of people wandered around the sailor's camp, Zhu Biao sent Li Cunyi back, and tomorrow he was going to board the boat and go north, and he would be accompanied by Jinghaihou all the way, so he didn't have to get in the way.

At noon, Zhu Biao had lunch in the camp, and when he arrived at the sailor camp, he naturally ate seafood, Zhu Biao didn't like to eat seafood very much, but he didn't pick it, and had a good chat with Wu Zhen during the banquet.

This person is worthy of his reputation, he has a lot of ideas about naval battles, and he also has revenge for the destruction of the Japanese invaders, but Zhu Biao just saw that he respected Li Cunyi a lot, and remembered the list he mentioned when he talked about Li Shanchang at the beginning, this person seems to be good friends with Hu Weiyong.

If this is the case, I am afraid that I will not be implicated in the future, Zhu Biao listened to Wu Zhen's thoughts on his face, but he kept thinking about whether to pull this person in his heart, after all, compared to the army generals, there are fewer talents in naval warfare.

Wu Zhen, Marquis of Jinghai, and Wu Liang, Marquis of Changjiang Yin, were both Huaixi nobles who followed Zhu Yuanzhang in the early years.

Just like Wu Zhen as early as the first year of Wu, he was worshiped as the deputy general of Zhengnan, and followed Tang He to conquer Fang Guozhen, he once entered the Cao'e River with the tide, smashed the enemy's dam, opened up the waterway, and unexpectedly reached the military stable.

Fang Guozhen was forced to flee to the sea, Wu Zhen went into the sea to pursue, and fought with Fang Guozhen in Panyu, from Shen Shi to Xu, captured all his warships, soldiers, and baggage, and forced Fang Guozhen to surrender. Later, Wu Zhen entered Fuzhou by sea, besieged the three gates of the west, south and water departments, and finally broke the city in a battle.

Such a talent is really rare, but let's look at his performance along the way, if he can, he will be transferred to the East Palace, and then let him stay away from Hu Weiyong in the future.

Wu Zhen had just taken over the position of the chief officer of the anti-Japanese army, and he had a lot of affairs, and after eating, Zhu Biao asked him to go down to deal with official business, and he was led to the beach to see the more than 100 warships of the sailors.

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 previous generation of building boats, Meng Chong, fighting ships, sea falcons, boats and other ships, there are many innovative ships in the Ming Dynasty, such as ultra-small net shuttle boats, shaped like shuttles, bamboo masts and wooden sails, with a draft of seven or eight inches, with 2-4 people, equipped with two or three shotguns, and two or three hundred ships in wartime.

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.

The trap-type fire dragon ship has a hole in it, a knife board and a nail board in the middle, and the soldiers who are ambushed are defeated by the enemy first, lure the enemy to board the ship, and activate the mechanism, so that the enemy falls from the upper layer into the middle knife board nail board.

There are many such ships with their own characteristics, and they are all actual combat types, such as Cangshan ships, wheel boats, sea boats, centipede ships, if you face the enemy, it can be said that the strength of the Daming Naval Division is the first in the world, and there is absolutely no match in the world at present.

Zhu Biao didn't return to the camp until it was dark, and he personally went up to see most of the ships, and also let the accompanying sailor generals explain in detail, he had learned the art of land warfare before, and he could say that he didn't know anything about the navy.

Rare opportunity is naturally to study and understand, not to refine but to understand, this is also Zhu Biao's habit, after returning to the camp, Wu Zhen rushed to visit, no matter what, he could not snub His Royal Highness the Prince.

Zhu Biao didn't see him, and he had time to get along in the future, not to mention that it was not a good thing to get close too early, so Liu Jin got a meal and went to bed early.

Early the next morning, set off to board the ship north to Qingquan, that is, the future Weihaiwei, at this time with the name of the Yuan Dynasty, the north and southeast are bordered by the Yellow Sea on three sides, the north and the Liaodong Peninsula are opposite, the east and southeast are across the sea with the Korean Peninsula and the Japanese archipelago, and it has always been an important place for the invasion of Japanese invaders.

However, Zhu Biao went first because he wanted to receive news from Jiang Side and Monk Daoyan, which was also agreed before they set off, and it was estimated that the plan had been carried out smoothly at this time.

Zhu Biao's ship is a building ship, and it was once taken by Zhu Yuanzhang when he was the king of Wu, which is quite luxurious, and there are many fleets guarding along the way.

I was a little disappointed not to sit on the most famous fortune ship in the Ming Dynasty, but there was no way, the fortune ship used in naval warfare was as tall as a city, non-human drive, all the wind, and suppressed the Japanese ship when the wind was downwind, such as a car running over the mantis.

Fortunately, the building ship is tall, and the coastal driving is quite steady, and Zhu Biao is not seasick when he sits, but it is a pity that the ship is too high, and the center of gravity is often unstable, and it is not suitable for long-distance sailing, so most of them only serve as the main force in inland river and coastal water warfare.

After Zhu Biao got on the ship, he also received several letters from Beijing, the situation in the court was tense, Hu Weiyong suddenly exerted his strength, Zhu Yuanzhang watched from the wall again, Yang Xian was about to be unable to hold on, and sent several letters to Zhu Biao for help, hoping that His Royal Highness the Crown Prince would pull him for the sake of his past achievements.

Zhu Biao shook his head helplessly, in fact, the reason why Yang Xian has not fallen is that Hu Weiyong is waiting for the prince's statement, after all, Yang Xian is a subordinate of the East Palace, if the prince exerts his strength, then the situation will be much more complicated, even the saint has to express his position.
