With Qin Ming's method of making gunpowder, the household department was responsible for finding raw materials and grinding them into powder.

The final proportions and production, on the side of the military department, are confidential.

Under Qin Ming's order, the people who were responsible for finding and grinding raw materials were the most trusted by Hubu Shangshu.

And the people in charge of the proportions and production of the military department have gone through various selections and tests, and they are required to be 100% loyal to the Chu court and will never leak secrets, and a group of people are making gunpowder.

At the same time, the Ministry of Industry also received Qin Ming's order to make a round long cylinder with fine iron according to Qin Minghua's drawing.

This thing is the barrel of a cannon.

The barrel is half a zhang long, about one and a half meters, with a diameter of 30 centimeters and an inner diameter of 20 centimeters, so the thickness of the round barrel is half a centimeter.

This caliber is not small, and the thickness is very thick.

In addition, the bottom of the barrel is not completely sealed, and there is an opening, similar to a thick iron door, which can be opened, filled with gunpowder, and then pushed the shell through the muzzle, so that the shell and gunpowder are tightly together.

Then cover the bottom muzzle and seal it tightly, and then it is necessary to ensure that the bottom is sealed.

Of course, there will also be a lead to connect the gunpowder, once lifted. Ignited, the bottom gunpowder exploded instantly, and in such a confined space, a large amount of gunpowder burned and burst out with huge force, which would push the cannonball out of the muzzle.

So, the cannon, so it was formed.

But the first shells were just iron balls, and the purpose was to shoot them like stones, smashing people, or smashing the enemy's city gates or something.

Qin Ming would not be willing to accept that the role of the cannon was just like this, so in his plan, the cannonball was to use a bomb.

At the same time as the cannon is lit, the cannonball is ignited, and the distance and the time of fall are planned to determine the length of the lead.

In this way, the cannon launches the bomb several hundred meters away, and the bomb fuse also burns into place, and when it hits the ground, it explodes, producing an effective bombardment of the enemy.

This is Qin Ming's series of ideas.

Of course, if you make a fire gun in the future, it will be an iron egg, not a bomb.

In short, Qin Ming has really made gunpowder now, so in the future, there will be not only bombs and artillery guns, but also rockets.

This rocket is not the one that flies into outer space, but on the arrow, a cylinder with flames is tied to it, and after it is ignited, the gunpowder in the circle instantly burns to produce thrust, and flies out with the arrow, which is much more powerful than the arrow shot by the bow.

There are a lot of ideas, Qin Ming must slowly realize it, and when he has established a powerful thermal weapon corps, who dares to disagree?

The production of gunpowder has been realized and stored in large quantities in the military department.

Qin Ming also strictly required them to be careful, and even not a trace of fire was allowed around the entire place where gunpowder was made, and anyone who dared to make a fire near the development of gunpowder would be a capital offense.

In this way, in a week, when the secretary of the military department reported to Qin Ming, he said that thousands of catties of explosives had been made.

The Ministry of Industry also produced hundreds of barrels and thousands of shells.

This Qin Ming was excited, and immediately asked the Ministry of Engineering to bring a cannon barrel and a few cannon shells, and asked the Ministry of War to bring a few catties of gunpowder and leads, and personally went out of the palace and went to an open space outside the city, eager to see if the cannon could succeed.

The first is to fill the gun casing with explosives, install the leads, and leave it quite long.

A small wooden cart was then used to load the barrel diagonally to the sky.

The bottom chamber was opened, the powder was filled, the lid was closed from the muzzle, the bomb was placed through the muzzle, and the fuse was ignited.

The crowd quickly retreated about twenty meters.

The next moment, the lead burned to the bottom of the cannon barrel, and a huge muffled sound suddenly came out at the bottom of the cannon barrel, and then, at the position of the gun, an iron ball was instantly pushed out, and with the gunpowder star that erupted at the muzzle, the cannonball instantly flew out into the distance.

Because the combustion of gunpowder in the barrel ignited the lead of the shell, the shell that flew out at this moment was also ignited, and the long lead burned rapidly.

It flew more than 100 meters before landing on the ground.

At this time, the lead had not yet burned out, and after waiting quietly for three seconds, there was a sudden loud bang, and the bomb wrapped in iron shell exploded instantly, and the huge force blew up the surrounding soil.

At the same time, the iron shell was torn apart by the huge force, and it flew out in an instant, and these fragmented pieces of iron alone could kill a few people within a radius of ten meters.

Seeing this scene, the secretary of the military department, the secretary of the Ministry of Industry, and the entourage were stunned.

Honestly, they didn't know what it was, but they knew that it rang twice.

The second explosion, they had seen Qin Ming's previous bomb, and they were not surprised.

But after the first sound, the bomb in the barrel actually flew out, what the hell is this?

This made everyone puzzled, and Qin Ming didn't bother to explain.

He smiled, only knowing that his weapon had succeeded.

"The Ministry of Works, in the future, all the shells and barrels you made will be sent to the Ministry of War. The military department is still in the book, you put the gunpowder in the cannon case. In the future, this will be the weapon of our Chu State to conquer the world! ”

After Qin Ming finished speaking, he took a deep breath.

The Ministry of Industry and the Ministry of War bowed down one after another to say that they obeyed the order, and at the same time, everyone around knelt down and shouted:

"Long live Your Majesty, long live the State of Chu......"

Qin Ming smiled with satisfaction and waved his big hand: "Go back to the palace!" ”

Looking at the back of Qin Ming leaving, the Ministry of Engineering raised his head and said to the Ministry of War:

"Your Majesty...... The man of God is also ......"

The military department Shangshu sighed: "Today, there is this emperor, and he should be the co-master of the world." Look at it, in the future, there will be only one dynasty in the world, the Great Chu Dynasty. There was only one emperor, the Chu Emperor Qin Ming......"

Around, other people listened, and they were all deeply shocked and agreed.

Especially when I looked at the cannon, heh, do you dare to disagree?

Back in the palace, Qin Ming, who had a hot weapon, was called excited. He only needs to wait now, wait for the agriculture of Chu to develop steadily, and wait for the grain reserves, and more.

Wait for the construction of the whole country to be a little better, and wait for the economy to go up a little more.

Wait for the army of Chu State, and the overall strength will go up a few points......

Wait for the development of firearms, and more.

……

At that time, it will be the time for him to take the initiative and sweep everything around him.

However, just when Qin Ming was planning everything and only needed time, he received a message.

It was another early dynasty a week later, Qin Ming was discussing the government with hundreds of officials, when Yu Ze hurriedly went to the palace, saying that he had received a report from a secret agent, saying that the five countries led by the southern country were planning to attack Chu again.

"Your Majesty, this time, on the grounds that the Chu State designed to frame the head of the Qingguo State Sect and the prince of the Aolai Kingdom and the prince of the Meng, they practiced the southern kingdom of the White State and the five kingdoms to attack Chu,"

In the main hall, the hundred officials were suddenly flustered, only Qin Ming smiled very calmly:

"Qingguo, Aolai and Mengguo, have finally reacted?"
