boom!

In the spring of the third year of Longqing, Xiangshan Temple.

Sun Ao's newly recruited three hundred-house flag soldiers had just been training for four months. The flag soldiers who had replaced thirty old bird guns and fifteen new pass guns were still practicing routinely. Suddenly, he heard a cannon sound coming from the direction of the newly built iron house, which scared the flag soldiers who were used to making a living on the river.

"Thousands of households can use it, all the cannons in Xiangshan!"

In front of Chen Mu, two cannons of different shapes were quietly mounted on the cannon cart, and smoke came out of one of the cannons.

“Not exploded.”

Chen Mu, who was standing far away, gritted his teeth slightly, raised his hand to wipe his face. There was no joy and joy on his face, but he opened his mouth slightly and took a deep breath. Then he nodded with confidence and said, "Riding a horse to find a place to land! Clear the chamber, and then put a flat amount of five kilograms of medicine to test the injection!"

Cannons are iron cannons, and copper cannons are more expensive and difficult to build. The Franji people built copper cannons in Haojing. If Xiangshan wants to build their own, they have to wait for those cannonists to learn something.

Using the big-haired style, the ink line is used to measure the sight. The shape of the new gun is thin in front and thick in the back is more scientific, making the gun body more beautiful and lighter in weight.

Chen Qianhu played a crucial role in this design improvement process. If he hadn't been involved in it from the beginning, he would have been able to blow up two less guns - this was the fifth gun made after the blowup was broken.

The new gun is four feet and two inches long and weighs three hundred and seventy kilograms, and has a very long range and is very powerful.

It was Chen Mu who planned to place the small cannon on the newly built 100-material warship in Xiangshan. Of course, it can also be used as a land war artillery, but it depends on carriages. It requires high road conditions and is more convenient in the north, and marching in the south will be restricted.

The Japanese pirates need to be prepared for in the southern land war. When dealing with Japanese pirates, General Qi's tiger squat cannon is the best choice. Although this thing is either not far away or has too low killing in Chen Mu's opinion, the Japanese pirates who cover a large area of ​​generally unarmed can achieve their full results.

So in order to welcome Zeng Yiben, he also imitated the tiger squat cannon.

The tiger squat cannons made by Qi Jiguang are different because some of them are transformed from old Zhejiang cannons and some are made of new iron. However, their usage is only two types: either pursue range, shoot at a large angle and shoot at two or three hundred steps and kill and kill enemies without armor; or pursue killing nearly a hundred steps and directly killing a large number of light armored enemies at a small angle close to direct shooting.

Chen Mu only chose a tiger squat style to imitate it at the Guangzhou Military Weapon Bureau. It weighs 77 kilograms, has a deep and wide muzzle, and emits fifty one or two lead balls, which is very killing and lightly shocking.

"Thousands of households! Three or four hundred steps are made, embedded in the tree and the humble position cannot be taken down!"

Chen Mu patted his forehead, and he shouldn't have someone riding a horse to look for it. He shouted: "You go over again, go and follow him again, take two rulers and measure how far it is. Go back to the numerical technique and measure it slowly!"

"Jiang Ji." Chen Mu shook his head and said tiredly: "Hurry up and make a tape ruler, make a log shell, and there is a rotating rod in the middle to hold the tape measure. It must be at least ten steps long, otherwise you will be exhausted to measure the distance of the gun all day long."

Guan Yuangu deeply agreed. Chen Mu told him that he made this thing called a tape measure, but the best craftsmen have been busy making cannons recently, and everything else has been delayed.

Not long after, the distance of the new gun test firing was calculated, and it was 297 steps, deeply embedded into a tree as thick as a waist.

The test firing continued, and the gun position angle was adjusted one after another, and finally it was calculated that the highest angle could hit 1,280 steps, but aiming at the angle and distance had no effect. The distance that could really aim at a radius of one zhang cloth was 100 steps, which could have at least 90% accuracy.

From 200 to 400 steps, the accuracy rate dropped to 50% or 60%, and the landing point is still between the round cloth.

The goal of 400 to 800 steps is not enough, and the landing point is roughly within three meters.

"This standard can meet the needs of warships."

Chen Mu nodded with satisfaction. From the sun came out until the afternoon, they were busy with this cannon. Now they can finally have a good meal. In order to celebrate the celebration, everyone was happy that they killed pigs for the craftsmen and flag soldiers inside and outside.

It will not be so troublesome to test the tiger squat cannon in the afternoon. The tiger squat cannon will be in a relatively mature shape here, not to mention that it is a small cannon that is shot, and there is no trouble of being as easy as a new cannon and not familiar with the standard.

The three cannons are bombed to test the kill range of high-angle, and the kill range of low-angle is enough.

The big horns were 140 steps to 200 steps, and the fifty pieces were spread so that even the gunners didn't know where they would hit them. The lead bullets were nearly inch deep into the soil; the low angle was thirty steps away from the hydraulic saw machine, which was cut by half an inch thick, was directly broken. The depth and shallowness were uneven, but the injury was astonishing.

Much stronger than a bird gun.

"Guan Jiang, if the iron pipes are enough for these two types of cannons, how long will it take for the craftsman to shoot after being proficient?" Chen Mu bit his lips and narrowed his eyes, looking at the opposite side of the not-too-distant sea. "The cannon will not be built for now. This cannon is like a gun, also called Guan Cannon. It will be enough with a tiger squat together for a while."

Chen Mu likes this kind of thing, and his military idea is only one - to let the enemy die on the road to attack.

Long-range firepower has been superimposed, and the attack level of the flag army is adjusted very clearly during training, which means that his flag army will add artillery during training in the future to further increase the combat sequence.

Two hundred steps away, the gate cannon will be hit first, and the tiger squats will be hit again when it is approaching 200 steps, followed by the routine operations of setting up rockets and shooting bird guns. If the tiger squat cannon is approaching, it will be possible to do it again, so basically there is no need for Deng Zilong to take risks with his body.

However, what Chen Mu didn't expect was that Guan Yuangu was stunned by his question. The old man looked at the two tigers and squatted with one passive cannon and asked, "Thousands of thousands of households, these three cannons consume more than one hundred workers. Not to mention the use of thousands of kilograms of iron, do you have to shoot again?"

A worker is a craftsman for a day.

It is not enough to play three goals, and you still have to continue playing and make the craftsmen proficient?

How many do you have to fight?

Guan Yuangu swallowed his saliva, looked at the big iron cannon worriedly, and said, "The working hours are nothing, it's too hard!"

The iron stored in Xiangshan, including the seized and transported from Bai Yuanjie, was only about 10,000 kilograms, and half of the bird gun was used to kill the bird gun. Now, in order to fire these three cannons, the rest was consumed almost the same. Chen Qianhu also planned to add collision angles under the waterline of the newly built warship. No matter how much iron stored in Qianhu is, it is not enough!

"We have to be proficient in fighting normally. This one uses less than 500 kilograms of iron. As for the iron saved, hey."

Chen Mu patted the cannon, and he felt very happy when he heard the echoes that were dull and then clear. "I have a way to get it!"

He planned to go to the surrounding garrison stations to inquire about what to do with old ones and new ones, and a thousand pounds of iron to exchange for cannons... He didn't know whether other garrison stations could do it, just Guanghai, the two guards in the South China Sea were disturbed by the pirates such as Zeng Yiben, so they were all soldiers. At this time, they had iron on their hands, and Chen Mu felt that they could get them all.

But the joy didn't last long.

Because it was smoking.

The beacon tower in the distance was smoking.
