Jiang Sheng couldn't think of this, but he knew one thing, and that was the secret, he was the secret. If you know someone else's secret, there are only two ways to keep it secret: one is to keep it secret, which is the safest way, because a dead person can't leak it; The other is to become your own person, since it is your own person, then the possibility of secret leakage is greatly reduced, because you can leak the secret for the first time, you can do it for the second time, and the object of your leak will be difficult to believe you, and the final result is likely to return to the first one.

Since Gongsun Du is willing to recruit them, naturally it is not for the sake of killing, so there is only the second one, becoming his own person.

Jiang Sheng suddenly felt that Gongsun Du had not appeared for more than a month before, perhaps just waiting for them to make a choice. But until now, they didn't say anything, so they came to the door in person, revealed the secret, and forced them to make a choice.

Thinking of this, Jiang Sheng was unstable under his feet and almost fell to the ground, but fortunately, he stabilized in time because he was old and fine, but his back was already soaked.

"Jiang Duzao, maybe the next words sound exaggerated, but what I want to say is that there are indeed very few things in this world that can make a certain curiosity, and shipbuilding is just one of them." Gongsun Du suddenly spoke.

The idea that had just risen in Jiang Sheng's heart was suddenly suppressed, but he couldn't help muttering in his heart: What Lord Taishou said is true or false? If it's fake, then isn't that what kind of sealing technology, axle drive technology, etc. are also fake? But if it's true, why is Taishou-sama curious about shipbuilding?

I couldn't figure it out, Jiang Sheng still replied quickly: "My lord, please, the keel of the type wheel ship is going to be laid today, if the adult sees it, he will be able to relieve the curiosity in his heart." ”

Gongsun Du nodded, walked forward, and said at the same time: "What's going on with this type of wheel ship?" ”

Jiang Sheng's heart moved, and the secret opportunity came, so he said: "My lord, it is more appropriate for Jiang Yi to say this, because this is what he thought of." ”

Gongsun Du glanced at Jiang Yi in surprise, and saw that although he was nervous, he was not weak-hearted, so he couldn't help but nodded.

Jiang Sheng gently pushed Jiang Yi, who was a little nervous.

The nervousness in Jiang Yi's heart disappeared slightly, and he said: "My lord, it's like this, according to the shipbuilding technology taught by the adult, we originally wanted to build a building ship directly. However, because the water flow of Liaoshui is not large, especially now that it is not the dry season, the width of the water surface is only about ten zhang, and the deepest part of the water is only a little more than three zhang, and it is not even possible to turn around, so it has to be another choice. ”

"Originally, according to what the adults said, the big than the building ship of the wheel ship is also very similar, and it should also be abandoned. But my subordinates thought—"

"First, compared with other warships, the wheel ship belongs to a new type of warship, such as a company warship, which can only be regarded as an improvement, not a new type of warship. New, it means that this does not understand, there is no experience of predecessors to learn from, the only thing that can be relied on is continuous attempts, find the omissions, and then modify and remedy. ”

Gongsun Du felt that this was really reasonable, and there was also a kind of expectation in it, so he nodded lightly.

Jiang Yi couldn't help but be overjoyed when he saw Gongsun Du's approval, and then said: "Second, it's this watertight technology. The previous generals, whether it was a building ship or a ship, a ship, a red horse, a rash attack, a fighting ship, etc., all kinds of warships, they did not have high requirements for water tightness. In other words, even if they don't, it doesn't affect them much. The wheels and ships are different, because of the different driving methods, they need to have good enough watertightness, otherwise they have not traveled far, it is likely that most of the water has been loaded with water, either the speed drops greatly, or the ship is in danger of sinking. ”

After hesitating for a moment, Jiang Yi said another speculation-

"My lord, my subordinates feel that this watertight technology is likely to have a deep connection with the wheel ship." After speaking, Jiang Yi stared at Gongsun Du tightly, because these two techniques were taken out by Gongsun Du, if he said that he understood, it must be that Gongsun Du knew more, and maybe he would get the answer.

Gongsun Du thought for a moment, and then replied: "Yes, your guess is very reasonable. ”

Well, is that yes or no? Jiang Yi was a little confused, but where did he know that Gongsun Du was not a shipbuilder, it was already very good to know this information, and where did he know their internal connection and so on. Therefore, in order not to be ashamed, Gongsun Du could only respond ambiguously, and slowly guessed with Jiang Yi and them.

Jiang Yi thought for a while and continued: "Third, it has a lot to do with the first, since the water surface is not wide enough and not deep enough, then it is better to simply build a wheel ship." In addition, the amount of wood required for a new type of wheel ship is very small, and the time required can be greatly reduced, which will certainly play a great role in the construction of a truly large wheel ship in the future. ”

Gongsun Du couldn't help but shrink his eyes, looked at Jiang Yi seriously, and then slowly retracted his gaze.

Although Jiang Yi and the others didn't understand what Gongsun Du meant, they didn't ask when they saw that Gongsun Du didn't mean to explain. In fact, Gongsun Du's heart was quite uneasy at this time, he originally thought that Jiang Yi would be able to build a Lianfang battleship, as he himself said before, only the ability to improve, and the ability to innovate is insufficient, so the ability can only be regarded as mediocre. There is no comparison with the famous craftsmen and masters of the Three Kingdoms period at the end of the Han Dynasty, You Hun, Pu Yuan, and Ma Jun. Now I found out that maybe it wasn't Jiang Yi who didn't have that ability, but the original Gongsun Du's lack of trust in him. Otherwise, it would not have been possible to reach the Sui and Tang dynasties, and this technology would suddenly explode and be able to build finished products.

It's a joke! Even in the first life, various technologies were updated very quickly, and it took a lot of time to complete them with repeated verification by borrowing supercomputers. The most likely outcome is that Jiang Yi discovered this technology at that time, but there was no chance to implement it, and in the end he could only form a theory, and then it was discovered, and it gradually matured over a period of several hundred years before it was really applied to ships.

"Aircraft carrier, maybe it's really not impossible!" Gongsun Du said to himself from the bottom of his heart.

"By the way, why is the main structure of that ship called the keel?" Gongsun Du asked again, "Like a human bone is called a human bone, the main beam of the house is also called the roof beam, and the main frame of the ship should be called the ship bone or the beam of the ship?" ”

Speaking of this, Gongsun Du also deliberately asked his mother back then, but obviously, the result made him very dissatisfied, and now that he has the opportunity, he naturally hopes to get a satisfactory result.

Jiang Yi and Gao Qiang didn't speak, they both looked at Jiang Sheng.

Jiang Sheng felt that there were so many accidents today, more than in the previous decades. Shaking his head slightly, Jiang Sheng replied: "My lord, if the reason is to change to someone else, I don't know much. ”

"Oh?" Gongsun Du thought to himself, is this still a secret that is not passed on?

Jiang Sheng's face showed a look of memory, and after a while, he said slowly-

"It was still a very young time, when I had just come into contact with shipbuilding, and when I heard the word keel, I asked, 'Isn't this a ship?' How is it a keel? Isn't it a boat that was built, but a dragon? My father didn't know it at the time, but my grandfather heard it and said—"

Water and land are divided, people drink water, but can not live in the water, even some good swimmers, but also follow the principle of not swimming in the water before the beginning of summer, after Halloween.

However, the southern rivers were all over the place, and they were more convenient than the flow of chariots and horses, so boats came into being.

Legend has it that dragons can be powerful and can rise and hide; If it is large, it will be cloudy and spitting fog, and it will hide the form; The rising is soaring between the universe, and the hidden is lurking in the waves. The most important thing is that it is the overlord of the water, and the water, and all the beasts in the water, are under its command. Therefore, when building ships, in order to have a good omen, the shipbuilders named the totem - the dragon, and for fear of angering the divine beast, they only took the keel as the main frame, and the whole was named the ship.

This is where the word keel comes from.

After Jiang Sheng finished speaking, Gongsun Du still looked unsatisfied, it seems that although this explanation is illusory, it is more acceptable to him. Not only Gongsun Du, but even Jiang Yi and Gao Qiang were satisfied with what they heard, and nodded subconsciously.

Later, several people realized that they had unknowingly arrived at the dockyard, that is, the place where the ship was built. The laying of the keel aroused Gongsun Du's curiosity, and he watched it carefully for a while under the introduction of Jiang Sheng and others. But it was only for a while, and he, who had seen mechanized operation, really didn't have much thought about this slow process that relied purely on manpower.

Therefore, after understanding the general situation, Gongsun Du definitely went back to deal with other things, especially the affairs of the foreign race. It has been a long time since the ice and snow melted, but the alien race has never appeared, which makes Gongsun Du have to be vigilant. He always felt that it was like the calm before the storm, which did not appear now, but only to continue to have more strength against him.

"Well, you've done a good job, just do it, figure out the watertightness technology as soon as possible, and build the wheelship." Gongsun Du first expressed his satisfaction, and then hinted, "Whether Liaodong can become as prosperous as the Central Plains in the future depends on you." ”

Jiang Shengren was old and refined, and he understood the meaning as soon as he heard it, so he said: "Yes, lord!" His subordinates must complete the construction of the ship as soon as possible. ”

When Gongsun Du heard Jiang Sheng's title, he took a deep look at Jiang Sheng, nodded, and said, "Well, okay, then so be it!" With that, he turned and walked away.

Jiang Yi and Gao Qiang didn't understand why Jiang Sheng suddenly called him the lord, but in the case of his continuous glances, they still hurriedly shouted together-

"Subordinates send off the lord!"

Gongsun Du paused, and then continued to step away, as if he didn't hear it, however, in fact, the corners of Gongsun Du's mouth were slightly upturned at this time, and he said secretly: Sure enough, it's an old fox!

When Gongsun Du's back disappeared completely, Jiang Yi was puzzled: "Ninth Taigong, do we really want to worship him as the master?" Gao Qiang also looked at Jiang Sheng without blinking, and it seemed that if Jiang Yi didn't ask, he would ask too. The two of them knew very well what it meant to call someone their lord, but it was a bit sudden, and besides, since that day, they had always regarded Gongsun Du as their good friend.

Jiang Sheng didn't know what they were thinking, but said, "This may be the best ending for us!" After speaking, without waiting for the two to ask again, they left, leaving the two of them standing in place with confused expressions You look at me, I look at you.
