The Tang Dynasty started from saving Empress Changsun

Chapter 95
Chen Jingke explained the principle of the bomb clearly, and at the same time explained the principle of the cannon to Li Shimin.

When he heard that he could launch bombs and iron balls weighing several kilograms ten miles away, Li Shimin's expression changed again.

He himself is a famous military master who has fought many battles, and he is well aware of the impact of this long-range weapon of mass destruction on warfare.

If the cannon is real, at least the city wall will be a decoration.

The city wall may be able to block solid bullets, but it will definitely not be able to stop this explosive bullet.

Just imagine, if thousands of these flowering bombs fell on the top of Chang'an City... Forget it, he didn't dare to think about it anymore.

This is not over yet, Chen Jingke also talked about the benefits of putting the cannon on the ship: "The cannon is very heavy, and it is inconvenient to carry one of several hundred thousand catties, and the logistical supplies such as shells are also troublesome."

"Placing it on a boat can perfectly solve these problems... As long as there is water that can pass through the boat, the cannon can reach it, stand on the shore and fire directly, and cooperate with the army's operations..."

Li Shimin immediately thought of Goguryeo and Baekje, and these two Liaodong countries were his next goals.

He was not sure of victory before, but if the cannons and gunboats were true, he would have the confidence to complete the feat of destroying the country.Completely eliminate the hidden dangers in Liaodong, and push your achievements to a higher peak.

Chen Jingke couldn't help showing off his 'design': "Not all ships and cannons can be used as gunboats... The ship I designed has a draft deep enough to sail in deep seas, and the sails can be adjusted with the help of wind in seven directions."

"Combined with astrology and compass, we can grasp the direction in the vast sea without getting lost, and then our big ship can sail freely on the sea."

"Also, the recoil of the cannon is very strong, and the general hull can't support it. The cannon I designed has a recoil brake, which can greatly reduce the recoil..."

The muzzle brake is a structure with holes in the muzzle and the muzzle. The principle is very simple, but the process of discovering this principle is not simple at all.

Humans have been using firearms for hundreds of years before they figured out that opening a few oblique holes in the muzzle of the gun can reduce the recoil.

It's just that this is too advanced for Li Shimin. He doesn't even understand cannons very well, so how can he know what recoil is, let alone why opening a few holes can solve this problem.

But he knew that these things were useful, so he wrote them down one by one.

Later, he simply said: "I will write all these down later... By the way, no one else knows about the gunpowder and bombs, right?"

Chen Jingke naturally knew the truth of keeping it secret, and said, "Don't worry, Your Majesty, these are all made by me, and not by others."

Li Shimin didn't doubt this, the spies had already sent back the news that Zhenren Chen was hiding in a small courtyard recently, and he didn't know what he was doing mysteriously, and he asked for instructions to go in and check it out secretly.

Fortunately, he chose to give Chen Jingke a little more trust at that time, otherwise he didn't know what would happen.

If the spy sneaked in at night to check and open the fire pocket...it would be a lot of fun.

Thinking of this possibility, he felt terrified, and at the same time decided that he must be more careful in matters involving Chen Jingke in the future, and not act rashly.

Chen Jingke wrote down the production techniques of gunpowder, cannons, U-shaped bottom sea boats, new sails, and star pulling techniques.

Among the more troublesome are sea ships and cannons.

He only knows that the general ship types are U-shaped and V-shaped, but he doesn't know the internal structure.The cannon only knows how it works, and how to cast it requires craftsmen to explore.

Seeing him bring out so many skills at one time, Li Shimin was a little numb. He didn't mention the reward at all. He just asked him to keep it secret and let him go.

Chen Jingke knew that he needed time to digest and process these things, so he resigned tactfully, and before leaving, he even invited the emperor and empress to go to the small square of Zixiaoguan to enjoy the fireworks on New Year's Eve.

"The brand-new fireworks I invented, launch the fireworks shells into the air and explode to explode the fireworks. It's very beautiful."

Li Shimin asked in his heart, "Is it the same principle as the cannon?"

Chen Jingke said casually: "Yes, the principle is the same as that of a cannon firing explosive bombs, but the amount of gunpowder inside is different."

"I made black gunpowder because I felt that the Chinese New Year was too deserted. I wanted to make some fireworks lively, so I made cannons and bombs by the way."

The corner of Li Shimin's mouth twitched, this kind of artifact was made by himself while playing, which made him feel so embarrassed.

He waved his hand weakly and said, "I see, I will go to see it on New Year's Eve, you can go."

When Chen Jingke left, Li Shimin took the document and read it over and over again, and began to think about how to make and use these things in his mind.

I don't know how long Ren Feng returned, and said: "Sage, it has been dealt with over there without leaving a trace. Only those onlookers are left. The servants don't know how to deal with it, so I ask the sage to show me."

Only then did Li Shimin come to his senses, he saw that it was getting late, and he had been sitting for more than an hour before he knew it.

Putting down the paper in his hand, he said: "Warning them not to talk too much is just... by the way, tell the Queen that I will go to her place in a while."

……

In the Lizheng Palace, after reading the information left by Chen Jingke, the eldest grandson Wugou couldn't hide his shock: "Are these... all true?"

Li Shimin nodded and said: "I have seen the bomb with my own eyes, and it is indeed real. You are a great nephew, you can change the world with just a little thing."

Changsun Wugou knew what he was thinking, and said, "Your Majesty is worried about the people behind him?"

Li Shimin said with a heavy heart: "Yes, how could I not be worried. Where are these people hiding? Why can't I find any clues? Why did Chen Jingke appear? What is his purpose?"

The eldest grandson Wugou also had no idea, said: "Hey, the people we sent to monitor him didn't find anything unusual, and he didn't have any contact with anyone."

Li Shimin said: "Either they have a more covert method of contact, or the other party has never contacted him, but I prefer the latter."

The eldest grandson Wugou agreed: "I think so too. No matter how covert the method is, it will take time. He is under our surveillance for twelve hours a day, so there is no chance."

Speaking of which, she seemed to have thought of something, and picked up those few pages and flipped through them again.

Li Shimin knew that she should have discovered something, and said, "Did Guanyin maidservant discover something?"

The eldest grandson Wugou took out the pages of Sea Ship and Astrology, and asked, "Will they be overseas?"

Li Shimin's heart moved, and he quickly picked up the few pages and looked at them. The more he thought about it, the more likely he felt.

"Why didn't I think of this? Only when you go to sea often can you have the opportunity to develop such a powerful sea ship and navigation skills."

"He also specifically emphasized sailing in the high seas. It is very likely that they are overseas... I said why I couldn't find any traces of them on land. It turned out that they were overseas."

The more Li Shimin spoke, the more certain he became, and he said pleasantly: "Guanyin maidservant, you are really my good wife."
