Zheng Zhilong couldn't wait more than Shen Junrong, and when he heard that Guo Zhiyuan's secret weapon was about to appear, he hurriedly ran out to see, and saw dozens of soldiers of the New Army walking up from the bottom cabin carrying a round shuttle-shaped object, the round shuttle-shaped object was closed all around, wrapped in grease-coated cowhide, only the top had a one-person size cover, and the tail was equipped with a blade-shaped runner, which looked very strange.

When the soldiers of the New Army put down the strange-looking round shuttle-shaped object, Zheng Zhilong couldn't wait to run over, curiously touching here and there, and could no longer suppress his strong curiosity, and asked Guo Zhiyuan: "My lord, what is this?" What does it do? ……”

Guo Zhiyuan couldn't help but laugh secretly when he saw that this pirate king of the original historical time and space was turned into a curious baby by himself, and said with a slight smile: "This is called a submarine, it can move underwater for a long time and does not need to be ventilated......"

(I guess the reader will definitely curse when he sees this, why did the submarines come out?) It's too! In fact, there is a misunderstanding here, when it comes to submarines, everyone will immediately think of modern high-tech, in fact, the principle of the submarine itself is very simple, as long as you have studied middle school physics can get it out (I remember when the middle school handicraft class asked us to try to make a toy submarine), the real high-tech part is mainly the power part of the submarine and the weapon system, you want Guo Zhiyuan to get a nuclear submarine that can dive hundreds of meters, of course he can't get it, But it's no problem to get a simplified version of the submarine that can only be driven by manpower and dive only a dozen meters. In real history, the Dutch physicist Cornelius Dreyer also succeeded in building the first submarine in human history as early as 1620 AD, so it is really not nonsense that the submarine appeared here. ）

Of course, this is a bit incredible for the Chinese of this era, so Zheng Zhilong's jaw was about to fall when he heard it, and he said in surprise: "Can you be underwater for a long time, and you don't need to breathe?" Isn't that the same as a fish?! ……”

Guo Zhiyuan glanced at Zheng Zhilong and didn't speak, later generations invented the submarine according to the principle of fish bionics, he just mentioned it casually, but Zheng Zhilong immediately thought of the fish, this Zheng Zhilong is really unusual, it seems that this person is indeed worth his own attention to see if he can use it for himself.

Zheng Zhilong's mind was on this strange-looking "submarine" at this time, but he didn't notice Guo Zhiyuan's strange expression, the more he pondered, the more he felt that this "submarine" was magical, scratched his head, and plucked up the courage to say to Guo Zhiyuan: "My lord, I... Can I command them to act with Shen, I... I want to see this dive... How exactly does a submarine move underwater? ……”

Guo Zhiyuan thought about it, and felt that it was okay to let Zheng Zhilong follow him to participate in the operation, if he wanted to let Zheng Zhilong use it for his own use, he had to find a way to let Zheng Zhilong slowly integrate into his team, of course, some core secrets were impossible for Zheng Zhilong to know, this person's heart had to be sharpened, and others didn't recruit a white-eyed wolf, so he nodded and said: "It's not impossible for you to participate in the operation, but you have to ensure that all actions are under command!" ……”

"Yes!" Zheng Zhilong was overjoyed, and saluted Guo Zhiyuan with a nondescript military salute like a soldier of the New Army, he may not have realized that he was imperceptibly influenced by Guo Zhiyuan, and he was getting farther and farther away from the original road to becoming a hero on the sea.

When Shen Junrong took Zheng Zhilong and the elites of the New Army selected to participate in the operation into the submarine one by one, the other soldiers of the New Army slowly lowered the submarine from the deck into the sea water with ropes, Shen Junrong They had already tried to ride the submarine before, so there was nothing to make a fuss about, but Zheng Zhilong took a submarine for the first time, and saw that the submarine really went down to the sea, but he couldn't feel the feeling of poor breathing in the cabin, and he was surprised and excited and quickly exclaimed: "It's amazing, it's amazing!" It's incredible! ……”

"What a fuss!" Shen Junrong rolled her eyes at Zheng Zhilong, and didn't bother to pay attention to him, so she ordered to start the boat quickly, the sailors stepped on the pedals, and drove the runner at the tail of the submarine through the linkage shaft, and the submarine started, Zheng Zhilong suddenly shouted again: "It's moving!" It's moving! The submarine is really moving! ……”

"Shut up! It's annoying! Shen Junrong, who was annoyed by Zheng Zhilong, scolded unhappily.

Zheng Zhilong hurriedly covered his mouth, Guo Zhiyuan asked him to participate in the operation, but he asked him to obey Shen Junrong's command in all actions, but he didn't be quiet for long, and immediately found the problem again, and couldn't help but ask again: "No, although the submarine is moving, but we are in the sea like this, and it is useless to see anything on the water surface!" ……”

This time, Shen Junrong didn't train him again, pointed to a cylinder connected to the top of the cabin, and said with a smug smile: "Just let you open your eyes again, save you from making a fuss, you go to that periscope and take a look......"

"Periscope?" Zheng Zhilong scratched his head, put his eyes in front of the cylinder suspiciously, his eyes suddenly widened bigger than the dragon's eye, and exclaimed, "Oh my God, how did this happen?" In the water, you can see the situation on the surface of the water clearly! …… I see the Dutch guards! He looks like he's looking at me! As he spoke, he jerked back. (The principle of the periscope is simpler, and elementary school students can make it.) ）

Shen Junrong was secretly amused when she saw it, but she was also like this when she used the periscope for the first time, so she didn't laugh at Zheng Zhilong, patted him on the shoulder and said, "Don't worry, he can't see us, my lord said, what kind of light is this using... The principle of refraction, you look like it's right in front of you, but it's actually far away from you......"

Zheng Zhilong breathed a sigh of relief and sighed: "Commander Shen, how do you say Lord Guo's brain is long?" How could such an amazing object be created?! ……”

Shen Junrong pouted and said, "It's rare and weird, let me tell you, you haven't seen our adults' abilities yet, what is this!" ……”

Zheng Zhilong was also full of curiosity about Guo Zhiyuan now, so he smiled and said, "Commander Shen, can you tell me about Lord Guo?" ……”

Shen Junrong waved her hand a little impatiently and said: "I can't finish talking to you about the adult's affairs for three days and three nights, it's almost time to get to the place, I'm ready to act, let's talk about it later!" ……”

Zheng Zhilong also became nervous when he heard this, it is said that although he is young, he has been mixed with pirates for a long time over the years, and he has not done anything like murder and arson, and his courage must be not small, but it is the first time to do this kind of thing to go deep into the tiger's den after all, although with the help of a submarine, they sneaked in unconsciously, but after going to the island, there are Dutch guards everywhere, and it will be a big trouble if you make a slight mistake!
