Gao Shixin looked at the mortar cannon and saw that the mortar cannon was very small, weighing only twenty kilograms, the length of the barrel and the tail medicine room was about two feet long, the barrel was about one and a half feet thick, and the inner diameter was about five inches.

The gun body is placed on the bottom plate, and the two ears on both sides of the barrel are stuck in the grooves of the gun stand. Needless to say, the wooden bottom plate and gun stand must have been carefully crafted by a little carpenter. It looks very exquisite. It is made of high-quality hardwood, painted with a layer of brown-red paint, and there are several brass studs on the wooden gun stand, and a dragon is carved on both sides of the gun stand, which looks very beautiful and is simply a work of art.

Another eunuch opened the wooden barrel, took out a small tube-shaped medicine bag from it, stuffed it into the barrel chamber, and pushed the medicine bag into the medicine room with a wooden stick, then took out an awl, stabbed it through the fire door at the tail, and then inserted a medicine guide tube into the fire door. Then a small eunuch put a shell in from the muzzle,

Although this cannon is very small, the shell is not small. An iron ball with a diameter of five inches is about nine pounds. The inner diameter is five inches, which is equivalent to more than one hundred and sixty millimeters. Such shells are not lighter than those of the three thousand kilograms of Red Arts cannon. Because the chamber pressure of this small cannon is smaller and the initial speed of the shells is slow, the barrel is short and the barrel wall is thin, and the weight of the cannon body is naturally much lighter.

Because the tail of the barrel of the mortar is hemispherical, the shell is put in and the medicine room is sealed. The friction between the shell and the inner diameter is small, and the loading is very fast. Put the shell in and it is loaded.

"Prince, please take a few steps back." The little eunuch who was about to let go said.

The little carpenter took two steps back, and the little eunuch became anxious: "Your Majesty, you're still too close."

"What are you afraid of? Are you afraid that my skills will not be as good as possible? This is a cannon I made by myself. Are you worried about me?" In fact, even the casting of the cannon body was also personally participated by the little carpenter. In the imperial city, the little carpenter built a smelter specializing in iron and copper smelter next to the Taiye Pool. From construction to production, the little carpenter participated in the whole process! In addition to recruiting a group of skilled craftsmen from the Ministry of Industry, many small eunuchs in the palace were sent to the smelter to be helpers.

As the saying goes, being with the king is like being with a tiger, but this sentence does not exist for those craftsmen. They don’t even know who the half-grown child who often makes mistakes is. They all think it is the young master of the noble family in the capital. Who knows that the half-grown child who often rolls up his sleeves to work with them is their Emperor!

The craftsmen who were sent to work in the imperial city were all the most skilled craftsmen. The little carpenters gave them much higher salary than the Ministry of Revenue outside, and they went down to work with them in person to discuss the problems together.

Therefore, the little carpenter participated in the whole process from the start of the cannon molding, to casting, to opening the mold, to polishing the inner chamber.

"I don't dare!" The little eunuch knelt on the ground and kowtowed repeatedly.

"Get up, go and fire the fire." said the little carpenter.

"Thank you!" The little eunuch stood up, and someone had already lit the torch on the other side. The little eunuch took the torch, pointed it at the cannon door of the mortar, and lit the drug-induced tube.

The drug induction tube burned, and soon ignited the medicine bag in the gun chamber. A dazzling red light flashed at the fire door, and a stream of white smoke rose up. At the same time, a tongue of flames spewed out of the muzzle. A shell flew out of the muzzle with gun smoke and flew straight to the sky, and white gun smoke rose from the muzzle.

The muzzle is aimed at the direction of Wansui Mountain, which is also called Coal Mountain. The reason why it is called Coal Mountain is because when Zhu Di built the palace, it was once a place where coal was piled up, so it was named Coal Mountain. In the Qing Dynasty, it was renamed Jingshan.

The shell flew to the highest point in the sky, then fell down, and accurately landed on the top of Wansui Mountain. The little carpenter could see from the telescope that a large stone cracked at the place where the shell landed. A big tree on Wansui Mountain was also hit by the bouncing shell. The trunk as thick as a bowl broke immediately and the trees fell to the ground.

"Change the flowering bullet!" the little carpenter shouted excitedly, waving his monocular lens.

The little eunuch cleaned the barrel with a wet mop, cooled the barrel at the same time, wiped it dry with a dry mop, then put a cylindrical fixed charge pack into the barrel, stuffed it into the medicine room, and then came over with a shell with a fire door, stuffing the shell with the fire door facing the sky through the muzzle, and exposed the fuse.

Another little eunuch opened a wooden box, took out a clock from it, placed it on a stone table, then took out a piece of fuse, cut it, inserted the fuse into the fire door of the shell.

"The time was not calculated wrongly, right?" the little carpenter asked the little eunuch who cut the fuse.

"Go back to the emperor, after careful calculation, I will definitely be foolproof." The little eunuch hurriedly knelt on the ground and replied.

The little carpenter nodded and ordered: "Let the fire!"

Two little eunuchs were responsible for igniting the cannon. One little eunuch stood in front, lit the fuse on the shell, and quickly retreated a few steps. The little eunuch behind ignited the drug-guiding tube on the fire door.

"Bang" the expansion of gunpowder gas, the cannon with flames came out of the borehole, flew into space, and smashed it hard towards the top of the coal mountain. A few seconds later, the shells fell on the coal mountain, falling between two big trees. The flames flashed, and white smoke rose, and the two big trees fell down in the smoke.

The little carpenter saw two towering trees falling down from the telescope, and he laughed: "Okay! Good things! If our army had more such powerful tools, why worry about Jiannu's immortality!"

Zhang Yong stepped forward and said, "Emperor, if you use the mortar cannon on the battlefield, it is ten times larger than this cannon. This cannon is only more than twenty kilograms and can shoot two hundred steps; if it is a 200-kilogram sky cannon, it can shoot one to two miles! One flowering shell weighing forty kilograms falls, and there is no reason for Jiannu to survive within a radius of ten feet! If the cannon is increased to three hundred kilograms and can shoot sixty kilograms, the power will be even greater."

"Brother Emperor, what are you playing?" The cannon in the imperial city alarmed King Xin, and he ran out with interest.

"Brother, we are playing the celestial cannon. Come here to see." The little carpenter greeted King Xin, took his hand to the mortar that was placed on the ground, pointed at the mortar cannon and said, "Brother, don't underestimate that this cannon is very small, it's very powerful. Come, let's try the power of this cannon for you."

After saying that, the little carpenter handed the telescope in his hand to King Xin.

King Xin took the telescope and asked, "Brother Emperor, what is this?"

The little carpenter smiled and said, "This is a Qianli Miles Miles. Pick it up and look outwards, and the big head is facing outwards, and the little head is facing himself, yes, that's it."

As the little carpenter ordered, King Xin picked up the telescope and looked at the coal mountain. He shouted in surprise: "Wow, the pavilion looks so close, just like it is in front of him!" As he said, King Xin also reached out to touch the peony flowers under the pavilion.

"This thousand-mile mirror can enlarge a very far place and look very close. In our hands, it is a toy, but the generals on the battlefield can find a very far-reaching enemy with this thing! There is also this mortar, we are just playing here, but when we go to the battlefield, it is a powerful weapon to kill Jiannu!" The little carpenter introduced to his younger brother with a smile.

Zhang Yong also picked up a pair of telescopes and looked into the distance of Coal Mountain. Suddenly he pointed to a crooked tree on Coal Mountain and said, "Your Majesty, Prince Xin, look, there is a crooked tree on this mountain. Yes, right next to the pavilion, there is a crooked tree. It's so unsightly. Emperor Majesty, let's use cannons to bomb this crooked tree?"

The little carpenter also picked up the telescope and looked into the Miaoting. Sure enough, he saw a crooked tree. He nodded: "Okay, aim at the crooked tree and fire it and blow it off!"

The telescope in King Xin's hand was actually aimed at Guan Miaoting. He heard Zhang Yonghe's brother's shouting and turned the telescope slightly. Sure enough, he saw a crooked tree next to the pavilion. He thought to himself: Brother and Yongwazi think this tree is not good-looking, but I think this tree is very good-looking. Thinking of this, King Xin grabbed his brother's arm: "Brother Emperor, Brother Emperor, this tree is very good-looking, okay?"
