Qin Huan couldn't stop the car as soon as he opened his mind.

All kinds of rockets have sprung up, including those used in naval warfare and land warfare. Some can be launched by carrying them on one's shoulder, and some can be launched on launch vehicles with dozens or hundreds of them launched together.

At the end, Qin Huan even thought of building a super rocket.

The rocket is half a meter in diameter and five battles long. It is also divided into two stages. Four boosters are tied to the tail. In fact, it is an enlarged version of the fire dragon.

We can use the cork of the previous hot water bottle as the material. It is the lightest wood. With the skill of Chinese carpenters, we can easily make a large cylinder with a diameter of half a meter and a length of five feet without nails.

Once it is made, the range and power are absolutely terrible in this era. The range may reach 20 or 30 miles. It can carry hundreds of kilograms of gunpowder to explode and equip it on board to attack coastal cities on land.

It is estimated that a small town in Europe can be razed to the ground with only a dozen or so missiles. As for the accuracy, as long as we launch more and master the angle and trajectory calculation, the approximate position will not be wrong.

Qin Huan decided to set up a rocket Research Institute immediately after the war to study and manufacture various firearms based on the principle of rocket propulsion.

"Shit, if I had these rockets, I would make a fart gun." Qin Huan looked at a large stack of paper and said excitedly.

I even plan to give up the development of artillery and jump directly to the second artillery in the future.

There's no way. The artillery of this era is too pit father. First, it's the flowering bomb. It's difficult to master the explosion time. Second, the artillery is too bulky and difficult to transport. Second, the loading is too slow.

After these problems are solved one by one, I'm afraid we can't do it for decades. And if you focus on rockets, who knows what will happen in a few decades?

In fact, he felt that in ancient times, rockets had more advantages than artillery, were simpler and easy to develop.

The problems of artillery are almost unsolvable now, and rockets are different, because the arrow body of rockets can be made of wood. According to the current craftsmanship of Chinese carpenters, they can almost make whatever they want.

As for why modern Europe did not develop rockets, but developed artillery first, Qin Huan estimated that they took a detour. This can be seen from the fact that countries competed to develop missiles in the late World War II. Finally, the facts also proved that rockets were the God of war.

Compared with Europe, the concept of firearm application in the Ming Dynasty was obviously much more advanced. Almost all the later thermal weapons can be found in the prototype of the Ming Dynasty.

For example, the tiger squatting gun is very much like a mortar, as well as mines, mines, divine fire flying ducks, swarms of bees, fire dragon water, etc. the concepts of these weapons are very advanced, but there is no in-depth research.

This is because there are no strong enemies around the Ming Dynasty, and the Chinese people's energy is not in this. Even so, the Ming Dynasty still made many firearms. If the Ming Dynasty looks around like Europe, or continues for another one or two hundred years, who knows what firearms can be developed into? Maybe we can make all kinds of rockets.

"Childe, what are you painting on it? Why can't I understand the same? "

Qin Huan stopped writing, leaned back on his chair, closed his eyes and outlined the future of the rocket. Xiao Xinru came in with a tray on which there were not only some snacks, but also steaming fragrant tea.

"Hehe, this is the king's killer mace to dominate the earth in the future!" Qin Huan smiled.

In my mind, the navy of Daqin crossed the ocean and came to Europe, and then countless rockets flew from warships comparable to treasure ships to cities and ports on the shore. There were screams of despair in the thick smoke and rumbling noise.

……

For several days, the two naval divisions were not fighting. The Qin army was busy searching for boats and repairing warships. The Chu navy was not idle. It was actually making gunpowder and putting it into wooden barrels.

At this time, Qin tie finally arrived at the foot of Yueyang City with his army and was cutting wood everywhere to build siege equipment.

Looking at the tens of thousands of Chinese troops on the tower, Li Dingguo sighed that he could only rely on the navy to defend Yuezhou city.

Yuezhou faces the river on one side and the lake on the other. If the other side only attacks the city by land and 50000 troops defend both sides, it is more than enough. He is also sure to hold for half a month. But if the other side's warship comes up, I'm afraid that as long as one round of shelling, everyone in the city will collapse and there will be no war.

On this day, the Qin army was finally ready, and the warships came again. Liu San also led the Navy up with confidence.

In the last battle, he had seen that although the other party's ship was large and there were many guns, it was just a show of airs. It was a great threat to the big ship, but he was powerless to the small boat.

Although he lost thousands of Brothers last time, it was because he was unprepared. This time, the boat not only prepared shields, wet quilts and cowhide, but also borrowed a lot of bows and arrows from infantry.

Of course, these are just to guard against each other's fire guns and thunder. The real killer mace is a hundred small boats filled with powder kegs and igniters.

But when the two fleets were closer, Liu San was stunned when he looked at the countless small boats behind the Qin warships.

But the arrow was on the line and had to be sent. The other party obviously came prepared this time. Even if he fled back to the water stronghold, it would not help. So he clenched his teeth and ordered: "send orders, and all the warships will rush up. No one dares to withdraw. Go back and pick his skin."

Liu Sany's water bandits were not only given heavy responsibilities by the eight kings, but also rewarded more than a dozen by the charming little lady. Therefore, he was very grateful to the eight kings and was more determined to keep Yuezhou than Li Dingguo.

Like last time, 200 large ships charged in front of each other to attract fire, and small boats took the opportunity to sneak attack from left to right. After several days of searching, the scale of small boats has reached more than 500 again.

The Qin army also collected four or five hundred small boats. If it were not for a hurry, I'm afraid they could get all 1000.

With Qin Huan's order, 500 small boats immediately gathered their sails and surrounded the war ships in the middle. They looked like stars holding the moon.

Qin Huan thought that he was not good at water warfare, but he had to give it to someone who was good at it. However, after the first World War, he was not in awe of the water warfare, so he simply commanded it himself.

Because he doesn't think it's difficult. Any bullshit tactics are empty. Whoever has more fucking ships can cause greater damage to each other's ships. He is the boss.

Most of the sailors on the boats of the Qin army also came from water bandits. They didn't prepare any quilts and shields, only long and short fire guns and a large number of thunderbolts.
