In order to build this battleship, Li Yuanjing did not hesitate to transfer most of the workers in the shipyard.

In order to cultivate newcomers, Li Yuanjing didn't even let go of the school.

All students have to participate in shifts, you don't need to do any important work, just follow the teacher, and you can do whatever you want.

It seems to be a coolie, but in the technical field, it is not possible to build a car behind closed doors, and the most important thing is to be well-informed.

Theoretical knowledge should also be combined with practical experience in order to maximize a person's ability, otherwise it will be a mere talk on paper.

"Can you do it? No, say it earlier, this king will be replaced now! ”

As soon as Li Shimin arrived at the dock, he heard Li Yuanjing's angry roar coming from inside the house.

Li Shimin couldn't help but feel a little surprised, at least he had never seen Li Yuanjing so angry.

But I was curious for a while, so I interrupted the officials around me who wanted to report and chose to stand here and listen to their discussion.

"It's not that you can't do it, but Your Highness, your requirements are too high, we have calculated many times, ordinary manpower can't meet this requirement at all, and you are not satisfied with what we have come up with suitable for reality, what else can we do?"

Listening to the voice of rebuttal, Li Shimin couldn't help but be a little surprised, could this person be Shi Lezhi?

How dare you scold Li Yuanjing like this?

"Tall fart, is this king dissatisfied with that thing? Are you a pig's brain? Battleships are going to deal with ships, even if it's a wooden ship, what's the use of you getting a crossbow on it? Planning to shoot them with a crossbow? ”

"But it's such a big iron egg, you can't shoot it at all......"

"If you can't shoot, you have to shoot!"

The quarrel in the house became more and more intense, and both sides had their own opinions, and neither of them would back down.

Of course, Li Yuanjing couldn't back down, why did he give the Tang Emperor to Li Shimin?

Isn't it because of this 5,000-ton steel giant ship, the only means of attack is ramming?

Can you imagine this?

Li Yuanjing thought a lot about this test ship at first, but when he got to the back, he found that there were very few places where weapons could be installed.

Therefore, in addition to sinking the opponent, the rest of the 5,000-ton steel giant ship is to rely on the soldiers on the ship to use bows and arrows and weapons to fight the enemy.

But this is by no means the picture of a naval battle imagined by Li Yuanjing.

Therefore, on this new ship, Li Yuanjing put forward the idea of weapon system at the beginning of the design.

The original idea was to have a large trebuchet in the front and rear, and use the trebuchet to attack the surrounding enemy ships.

But only two trebuchets will not work, and the flanks will also have to be protected to a certain extent.

But the width of this ship is only seven meters, this width is not at all possible to install trebuchets, the front and rear ends can also use the space to adjust, if you flank, you can only separate the entire battleship, even so, you can't adjust the angle of attack, if the sea shaking amplitude is too large, there is also a possibility of smashing yourself before the attack is launched.

Therefore, this idea was quickly canceled, and in its place, it was the giant crossbow proposed by the craftsman, according to this idea, Li Yuanjing decided to change the crossbow arrow into a large iron ball.

However, the big iron ball is not the only one, it can be replaced with ceramics, fill it with fire oil or something, and then launch rockets to turn the opponent into a fire ship.

But unfortunately, several experiments have proved that this idea is feasible, but the technology is not up to it, and they cannot launch the iron ball farther, and the farthest distance is only twenty or thirty steps.

This is a world of difference from the minimum of 200 steps required by Li Yuanjing, and it is also the main reason for their quarrel today.

At present, the construction of the entire warship has entered the final stage, but at this time, the weapon system that Li Yuanjing expects the most has not made any progress.

It's ...... to play hairy.

"Your Highness, the student has a not-so-mature idea...... "A teenager stood at the back of the crowd and whispered timidly.

He had considered this idea before, but he was soft-spoken, and so many bigwigs were helpless, and if he rashly stood up, he would inevitably become the target of public criticism.

But now that both sides are arguing so fiercely, the problem is still not solved, but it is getting worse.

He didn't know if it would work, but it was always right to give it a try, right?

Anyway, they wasted so much time and energy, not this time.

"Say!" Li Yuanjing's face was pale, but he still gave this little guy a chance to speak.

This is the characteristic of the shipyard, no matter when, no matter who is discussing the technical aspects, they cannot refuse the idea that anyone proposes, whether it is mature or not.

Of course, everyone also has the ability to discriminate, and what you are given is just a chance to speak, but if your idea is obviously wrong, then don't think about passing.

"Can we use the steam engine?" The boy said cautiously.

"Steam engine?" Li Yuanjing was stunned, and suddenly felt as if he had a head.

"Yes, the crossbow bolt is pulled backwards, but it takes too many people to pull, and the experiment is not good, the student once tried an interesting experiment below, although it was only a small experiment, but found that the effect was really good." The boy stood up timidly and took out a small piece of rope from his body.

Then I directly found a paper ball, and used some existing molds to pose a bow and crossbow shape, and then you can clearly see the trajectory and distance of the paper ball's movement.

At this time, the young man changed the mold in a different way, the same as the original shape, but the power was not maintained on the bowstring.

A new ball of paper was taken and placed in place, the boy pressed the rope with one hand, and the other hand pulled the other end of the rope under the table, and then the hand that pressed one end of the paper ball suddenly released, and everyone found that the trajectory and distance of the paper ball were almost half the distance than before.

A picture suddenly appeared in Li Yuanjing's mind, and this structure did not change much, but only changed the place where the force was exerted.

Some are similar to the principle of compound bows, but some are different.

The previous stretching and compaction is actually a way to accumulate force, theoretically speaking, regardless of the material factor, as long as the steam engine can provide enough power, then this idea is completely feasible.

"That's a good idea, arrange an experiment immediately!" Li Yuanjing commanded directly.

The principle of using the steam engine is completely feasible, as for the power, this is naturally not to worry, only a small part of the steam is used here, and it is enough to install a few small boilers and steam engines on the ship.

A few designers who can barely be called big guys are frowning and thinking about this problem, and they also feel that this idea seems to be feasible.

Of course, the problems are not non-existent, but these are not important, their research idea is to find a feasible direction first, and then solve the problems found one by one, and the final product is what they need.

Li Yuanjing wanted to go directly to the artillery, but now he doesn't even have gunpowder, where can he go to the artillery? And even if there is gunpowder, relying on the current technology, it is fundamentally realistic to use artillery, so don't be too ambitious.

Of course, what are you doing with artillery?

Playing with each other's wooden boats?

Or play with each other's sampan boats?

Taking out the steel battleship is enough to bully people......
