Rumble!

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

Sun Ao's newly recruited banner army of three hundred households had just been trained for four months, and the banner army with 30 old bird guns and 15 new guan guns was still in routine drills, when he suddenly heard a cannon sound from the direction of the newly built iron mill, which frightened the flag army who were accustomed to begging for a living on the river.

"Qianhu, it can be used, we have all the cannons in Xiangshan!"

In front of Chen Mu, two guns of different shapes were quietly erected on the gun carriage, and smoke came out of the muzzle of one of the guns.

"It didn't blow up."

Chen Mu, who was standing far away, gritted his teeth slightly, raised his hand and wiped his face, there was no joy or sorrow on his face, he just opened his mouth slightly and inhaled deeply, and then said with a fixed head: "Ride a horse to find the landing point!" Clear the chamber, and then load the flat amount of five catties of medicine for test firing! ”

The cannon is an iron cannon, the copper cannon is more expensive and more difficult to make, the Franc machine man made the copper cannon in Haojing, and Xiangshan wants to make it himself, so he has to wait for the gunsmiths to learn something.

With the system of large hair, the ink line is used to determine the crosshair, and the shape of the new Guan gun is also more scientific in the front and thick in the back, which also makes the gun body more beautiful and lighter.

Chen Qianhu played a crucial role in this design improvement process, if he hadn't blindly mixed it from the beginning, he should have been able to blow up two fewer cannons - this is already the fifth cannon made after the explosion.

The new cannon is 4 feet 2 inches long, weighs 370 catties, and hits 5 catties of bullets.

It is a small cannon that Chen Mu intends to place on the newly built Bailiu warship in Xiangshan, of course, it can also be used as a land war cannon, but it has to be pulled by a carriage, and it has high requirements for road conditions, which is more convenient in the north, and the march in the south is more restricted.

What you have to guard against in the southern land war is the Japanese Bandits, and to deal with the Wolves, Qi Dashuai's Tiger Squat Cannon is the best choice, although this thing in Chen Mu's opinion is either not far away or the killing is too low, but a large area covering the generally unarmored Japanese Bandits can get all the work.

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

The tiger squat cannon made by Qi Jiguang was not the same because part of it was transformed from the old cannon in Zhejiang and part was made of wrought iron. And its use is only two ways, either the pursuit of range, with a large angle projectile to hit two or three hundred steps of fall killing, to hit the unarmored enemy; Either pursue the killing of nearly 100 steps, and directly kill and injure a large number of lightly armored enemy troops at a small angle close to direct fire.

Chen Mu only chose a tiger squat system to imitate in the Guangzhou Prefecture Ordnance Bureau, weighing seventy-seven catties, with a deep and wide muzzle, and fifty one or two lead pellets, which were heavy and lightly shocking.

"A thousand households! Three or four hundred steps, embedded in the tree and can't be taken down! ”

Chen Mu patted his head, he shouldn't have let people ride a horse to find it, and shouted: "You go over again, go and the two of them follow him, take two step rulers to measure how far it is, and then go to a counting technique, measure slowly!" ”

"Guan Jiang." Chen Mu shook his head and said tiredly: "Hurry up and make a tape measure, make a log shell, and there is a rotating rod in the middle to retract and put the tape measure, at least ten steps long, otherwise you will be tired to death from measuring the distance of the cannon all day long." ”

Guan Yuangu thought so, Chen Mu told him to make this thing called a tape measure, but recently, the best craftsmen were busy making cannons, and everything else was delayed.

It didn't take long for the distance of the new cannon to be test-fired at 297 paces, deep into a waist-thick tree.

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

Two hundred to four hundred steps, the accuracy rate drops to five or six percent, and the landing point is still between the round cloth.

From 400 to 800 steps, the goal of a radius of one zhang is no longer enough, and the landing point is roughly within three zhang.

"This kind of system can meet the needs of warships."

Chen Mu nodded with satisfaction, from the sun came out to the afternoon, they were busy with this cannon, and now they can finally have a good meal, in order to celebrate the killing of pigs by the craftsmen and banner soldiers outside the busy house, they are all happy.

It will not be so troublesome to test the Tiger Squat Cannon in the afternoon, and the Tiger Squat Cannon will already have a relatively mature form here, not to mention that it is still a small cannon that plays shotguns, and there is no trouble such as being easy to blow up and not being familiar with the system like a new cannon.

It is enough to blast out three guns to test the large-angle range kill and low-angle kill respectively.

The Great Horn was one hundred and forty paces to two hundred paces, and fifty were so scattered that even the gunners did not know where they would hit, and the buckshot was nearly an inch deep into the earth; At a low angle, the half-inch thick planks cut by the hydraulic sawmill thirty paces away were directly broken, and the deep and shallow damage was uneven, but the injuries were amazing.

Much stronger than a bird's gun.

"Guan Gong, these two kinds of cannons, if the iron pipe is enough, how long will it take for the craftsman to be able to fight one after he is proficient?" Chen Mu bit his lip and squinted his eyes, looking at the other side of the sea that was not too far away, "Don't build a cannon first, this cannon is the same as a gun, it is also called a Guan cannon, and together with the tiger squat, it should be enough for a while and a half." ”

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

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

Two hundred steps away, the cannon bombarded for a while, the tiger squat near two hundred steps and then bombarded for a while, and then the conventional operations of releasing rockets to hit birds, if the tiger squat cannon was approaching, it would be possible to do it again, then basically there would be no need for Deng Zilong to risk himself.

However, what Chen Mu didn't expect was that Guan Yuangu was stunned by his question, and the old man looked at the two tigers squatting at one Guan cannon, and asked: "Qian, Qianhu, these three cannons cost more than 100 jobs, not counting the waste cannon and thousands of catties of iron, do you want to fight again?" ”

A craftsman is a craftsman for a day.

It's not enough to play three doors, but also to continue to play, and to make craftsmen skilled?

How much does that have to be fought?

Guan Yuangu swallowed his saliva, looked at the big iron cannon worriedly, and said, "There is nothing in the working hours, it is too much iron!" ”

The iron stored in Xiangshan, counting the seized and Bai Yuanjie's transportation, is only about 10,000 catties, and less than half of the bird guns are consumed, and now in order to fight these three cannons, the rest is consumed about the same, Chen Qianhu also plans to add a collision angle under the waterline of the newly built warship, and the iron stored by Qianhu is not enough!

"Let's be skilled and normal to fight, this uses less than five hundred catties of iron, as for the provincial iron, hey."

Chen Mu patted the cannon off, listening to the first dull and then the clear echo in his heart, "I have a way to get it!" ”

He planned to find the flag army to inquire about the surrounding guards, and get something to exchange the old for the new, and the thousand catties of iron for the cannon...... He didn't know if other guards could do it, but the two guards of Guanghai and Nanhai were disturbed by pirates such as Zeng Yi, and at this time they had iron in their hands, and Chen Mu felt that they could get it.

But the joy didn't last long.

Because it's smoking.

The beacon tower in the distance was smoking.
