At Shi Lang's strong request, Chen Jiangkui asked one of the submarines to perform diving. Shi Lang had a very good reason. You didn't let me see how this thing dived, and how did I direct this rare warship to combat? Chen Jiangkui originally wanted Shi Lang to see the diving performance, but it felt so good to cheer Shi Lang up his appetite. Of course, this was also to further strengthen the mystery of the submarine in Shi Lang's eyes, so that Shi Lang had more psychological confidence in crossing the sea.

In fact, everything was ready. As soon as Chen Jiangkui issued the order, the observer in the submarine received the demonstration instructions through the periscope. Eight people responsible for driving the submarine immediately began to pull the lever and drive the submarine forward.[]

Waves rose at the tail of the submarine, and then began to move forward. Shi Lang saw that the submarine was getting faster and faster. Not far ahead, the submarine suddenly sank. After a while, the submarine plunged forward and plunged into the water, until the protruding protruding in the middle sank into the water, and only a whirlpool was swaying on the sea surface, and the entire submarine disappeared without a trace.

Shi Lang looked at the quiet sea, not sure whether the round and rolling monster ship had sunk or dived. Well, even if he dived, how deep the dive was and how fast the water was, he could not see anything. The more this happened, the more Shi Lang wanted to get on the boat and see what was going on. Of course, he agreed not to get on the boat, but - but he really wanted to get on the boat and take a look. It would be better to operate it yourself. Of course, it would not work for the time being, but one day he would have to get on the boat and take a look.

Chen Jiangkui didn't give a detailed introduction to the submarine. He just paid attention to the sea and talked to himself about some topics that were not nutritious. As he talked, he saw big waves swaying on the sea in front of him, and then something similar to the protruding platform on the submarine just now appeared. The waves became bigger and bigger. Immediately, a round submarine emerged from the water, like a huge whale rushing to the surface of the Shanghai area. This strange situation shocked Shi Lang.

Finally, Shi Lang believed that the submarine could really dive. If you want to dive, you can dive and if you want to float, you can float. This is simply amazing. Shi Lang immediately thought that this submarine would be used for sneak attacks, it would be really unique. No wonder Chen Jiangkui said that this submarine would be specially used to deal with iron ships.

Later, Chen Jiangkui told Shi Lang about the parameters of this submarine, such as the water speed and underwater speed, the diving depth, the longest diving time, etc. These must be known to Shi Lang, otherwise Shi Lang would be unable to command it at all, because the attack of iron ships cannot rely solely on submarines, but also the cooperation of surface ships. The Japanese iron ships are equipped with evil submersibles, so if there is no siege of surface ships, it is believed that submarines will be difficult to attack the iron ships.

With the secret weapon of the submarine, Shi Lang's confidence has indeed skyrocketed. Although Chen Jiangkui did not tell him what kind of attack method the submarine was, Shi Lang believed that since the submarine was so magical, the submarine's attack would inevitably be very magical. As for Chen Jiangkui not saying it, of course it was kept secret.

In fact, the submarine was driven out and towed to Taiwan, but the torpedo has not yet been seen, so the submarine's attack methods are really primitive and hard to describe.

Zhang Kewang's 30,000 soldiers arrived at Nanyu Township Island ten days earlier, and was conducting basic firearm training on the island. The ten-day training was obviously too short, and it can be said that he could not practice anything. However, this is better than not even firing a gun. The 200 ships rented by Shi Lang also need to be run-in with people and ships. According to Shi Lang's estimate, there must be at least another five days. During these five days, Zhang Kewang's men and horses can also hurry up and conduct five days of intensive training, because when they arrive in Luzon, they will have to go directly to war against the Japanese.

Chongzhen had no such plan to take out the submarine that had just been successfully tested and lend it to Shi Lang to command the iron ship to attack the Japanese. However, when Zhang Xianzhong adopted Shi Lang's strategy and proposed to rent the ship, Chongzhen made a conspiracy.

The combination of Zhang Xianzhong, a land thief and Shi Lang, a sea thief, cannot be underestimated.

Let’s talk about Shi Lang’s battle plan across the sea, perhaps it is the most targeted strategy for crossing the sea.

The Ming Dynasty occupied all these islands between Nanyu Township and Fuga Island, and of course it was actually taken over by Zheng Zhilong's pirates. If the Japanese intercepted between Nanyu Township and Fuga Island, they would be enemies with the Ming Dynasty. The Japanese were indeed avoiding direct war with the Ming Dynasty, but only protested to the Ming Dynasty through the mouth of the puppet king Abu of Luzon. Of course, the Ming Dynasty could only express regrets about this kind of protest. The Ming Dynasty was regaining Liaodong, and it was beyond the reach of Zhang Xianzhong's surrender and rebellion. Similarly, he could only express deep regrets about Shi Lang, who was originally a pirate. Before he recovered Liaodong, the Ming Dynasty probably could not control these bullshit matters. On the other hand, the Ming Dynasty protested against the Japanese's intervention in Liaodong. After all, the Japanese were guilty and had a sloppy eye to each other. Therefore, the diplomatic war was just a gesture, and neither side took it seriously.

Since it is safe to reach Fuga Island, what you need to consider when crossing the sea is the distance between Fuga Island across the sea and climbing onto the Luzon main island. The Japanese occupied the closest landing site to Luzon main island and Fuga Island, but when you go west, the coast of Luzon Island is only fifty kilometers away from Fuga Island. Such a short strait, there is no need to consider the speed of the ships at all. Two hundred small boats line up, line up on both sides, protecting the middle channel, and everything will be fine. The strait is not a vast ocean, the space for naval battles.

Only when it is limited to these fifty kilometers of straits, the speed of the ship is not a key factor. Shi Lang's wolf pack tactics, as long as the number of small boats siege the coming enemy ships, as long as the number of ships is overwhelming, and the ship is equipped with enough rocket launchers, it is enough to deal with the enemy ships. This is obviously much easier than the naval battle of the Taiwan Strait. On the ocean, iron ships have the advantage of firepower and have more speed advantages, which is almost invincible. And between the narrow straits, the effect of the speed of the iron ships has been greatly reduced, providing opportunities for the wolf pack tactics.

What made Chongzhen feel strongly uneasy was that the Japanese steam power had been installed on the ship and was almost certainly practical, while the Ming Dynasty steam powered ship was still under test.

Obviously, the Japanese had increasingly powerful technical advantages in sea warships. In order to offset the Japanese's maritime advantages, how to kill two iron ships became a problem that Chongzhen thought about.

Regarding the iron ship problem, Wang Chengen felt that it could be completely possible to try the tactic of submarine sneak attacks to solve it. Wang Chengen said this:

"The two Japanese iron ships are thorns in our eyes, even if they can kill one! While the Japanese iron ship is still in Luzon, we lend the submarine to Shi Lang and ask him to kill the iron ship. If he doesn't help, he will destroy the iron ship. Afterwards, he pushed Zhang Xianzhong, which is better than finding another opportunity to destroy these two iron ships directly."

Chongzhen was unsure, just because the torpedo had not been successfully tested, so he said:

"The submarine has no torpedoes, so what can I do to strike the iron ship? Don't tell me to float on the water and bomb it with a rocket launcher."

Wang Chengen smiled and said:

"Your Majesty, it's not that serious, there are no torpedoes, but we have mines. After the submarine approaches the enemy ship, it can release mines. These mines are specially customized for iron ships. Haha, they are magnetic mines. When they encounter iron ships, they will suck them up. Due to the effect of magnetism, it will detonate the mines, which is enough for the iron ship to drink a pot."

Chongzhen still shook his head and said:

"This method is good, but the Yamato is protected by the submersible. What should I do if it releases the submersible?"

Wang Chengen also had a headache about this submersible, but there was no way out. He had to bite the bullet and said:

"The Japanese submersibles have cable submersibles that can use mines to blow off cables, and the submersibles will become waste. Of course it is not that easy, but if you don't try, how can you know that you can't kill them? Besides, if you really fight hard, you can't float half of your body and use a rocket launcher to close to the launch. It's a good deal to replace a wooden submarine with an iron ship."

"But what should I do if the submarine leaks the secret?" Chongzhen was of course very precious to the submarine, and he also hoped that it would suppress overseas corps such as Shi Lang!

Wang Chengen had no choice but to comfort his dear emperor:

"Your Majesty, we will only lend it to him and not allow him to board the ship. Besides, after our torpedo is successful, what if Shi Lang knows the secret of the submarine!"

"Oh, if that's the case, there's no need to be afraid that he will copy it."

"Of course, he can't just copy it easily. Just try to be careful."
