The last major order of the Beiyang Shipyard was for the sheath steel plates of the steam ship, using the technology of forging and riveting large steel plates.

Not to mention, there are many skilled craftsmen in the world, but only the Beiyang and Xiangshan shipyards are the cheapest, because they are the most skilled.

In the past, only Deng Zilong's dog leftovers and Shao Tingda's boats had such strange needs, which brought professional sledgehammer picking experience to the craftsmen of Xiangshan Shipyard.

The craftsmen of the Beiyang Shipyard are also from Xiangshan, so they will too.

In addition to this, there are many who are capable and few who are proficient.

It's not easy, and it's expensive.

Up to now, the Tianchang Railway from Tianjin to Changping, the Tonghai Railway from Tongzhou to the north to Wulianghai, and the Yanda Railway from Yanqingwei to Datong, there are ninety-three Qinglong military trains running on the three sections of the railway, and there are only three dragons, which are the kind of dragon head military trains in the painting that Wanli gave to Chen Mu.

The rest are copper shells and iron shells, metal is much cheaper than wood, it is easy to use, not to mention easier to process, and not easy to damage.

At the beginning, Zhou Sijing, the director of the Steam Bureau, felt that since he didn't have to work hard to make a dragon, he would brush it with some color, because of the name Qinglong, so from the front of the car to the back of the trailer were painted with cyan, and the four Huo De Xingjun were not used much by the railway, and Zhou Sijing was also idle.

Later, it didn't work, Beiyang gradually felt that transportation was unfavorable, the capacity of this thing is always the bigger the better, the faster the better, if there is no or the conditions do not allow, the small slow can also be used, but as long as there is a chance, it is the right thing to say how big it can be for military supplies.

There are more Huo De Xingjun used by the Steam Bureau for military columns, and Zhou Sijing can only discuss the unnecessary processes with Ye Mengxiong, the customer, can you not want the dragon shell? Can the color be removed? Is there a problem with the shell being ugly?

Ye Mengxiong naturally has no problem, as long as it can run, it is safe, heavy-loaded, and fast, and everything is good for him.

Therefore, the efficiency of making Huo De Xingjun has improved a lot, and the effort of producing four units in the past can now build sixteen units.

Compared with the assembly of parts outsourced to various subway factories, the production time that used to delay the most was the making of shells and decorative objects, but now it is much faster to lose them.

However, even if it was produced later, the appearance was different, and until now, Zhou Sijing has not been able to make a fixed model for the Huo De Xingjun of the Qinglong Army.

The earliest shell was simply a large square iron shell, and later the emperor reported that lying on the roof of the car to drive the green dragon was too anti-human, especially in winter to Wuliang Sea goods, which could freeze people to death, and later Zhou Sijing made a small black room with windows in front of the front of the car, and several key buttons were placed in the house.

But it was still too cold, and the wind kept pouring into it was not good for the efficiency of the boiler, and later the reproduction was equipped with glass, and the small black room of the cab was specially separated from the boiler room at the back with a door, and the machine parts such as the button connecting rod were also hidden in the wooden wall, which added a little rest space for the workers in the boiler room.

But this is still anti-human, the emperor is tired of standing and looking ahead through the glass window, and he can't see the outside when he sits down and straightens his neck.

So Zhou Sijing lowered the position of the glass window a little lower, and the cab finally had a fixed chair.

In terms of lighting, there is a lamppost with a slight forward extension in the middle of the front of the car, a kerosene lamp with a condenser and a thick wick in a glass cover fixed with iron wire, the condenser on the back is made of porcelain, the interior is designed with a gas pipe leading to the rear, and there are two kerosene lamps on the roof, three lamps for night lighting.

These three lights are not for the emperor to see the road, even if there is a spotlight in front of the car, it only allows the emperor to see more than ten steps ahead, and the main function of the three lights is to let others see them...... The speed of the fully loaded Qinglong army is about the same as that of a human jogging, and as long as a person sees it, he has time to dodge.

The biggest problem is the beasts on the road at night, and there may be man-made damage, so recently Zhou Sijing has added an iron plowshare like a collision angle to the front of the newly produced Qinglong Army Column near the ground, regardless of whether it is a man, a beast or a wood on the rails, it can be shoveled aside if it hits.

The improvement of the truck has nothing to do with Zhou Sijing, the truck is made by Beiyang, the earliest is a large wooden board with uniform specifications, there is no guardrail on the four sides, the goods are placed on it, and people stand on it, and later because the flag army accidentally fell asleep against each other, this increased the wooden guardrail.

After that, Beiyang has been trying to find the limit of the truck's bearing, and in order to maintain the combat effectiveness of the soldiers, the trucks in the first two years were still mixed with people and goods, and last year in order to make better use of the space, the people and goods were separated, and then the flag army box was simply separated from the cargo compartment.

In fact, the exterior looks basically the same, and the detachable wooden wall outside the guardrail is used, but there is a difference.

The carriage of the flag army is very large, there are folding planks on both sides of the guardrail and the floor of the middle compartment, which can be pulled out to sit people, eleven people can sit on each side, and three people can sit side by side in eleven rows in the middle, and there is almost no difference between the cargo box and the soldier box, but there are no these chairs; The wooden wall can be capped or unsealed, and there are wooden windows on the wall that can be opened and closed, which can be ventilated and observed from the outside world, and the window can be opened to dance with a knife or shoot with a gun.

These changes were accompanied by the use of the flag army, and they complained again and again and fed back to the Beiyang Military Government, and then the design was modified one after another, and now the carriage has basically become customized.

The rules set by Ye Mengxiong, an important minister of Beiyang, that all the Qinglong military columns driving in the pass must ensure that they carry a military box and a cargo box, which means that there must be at least one Beiyang Army with a general flag before this military column can start.

Of course, in addition to the Beiyang standard carriage, there is also the non-standard model of Wulianghai Qi Jiguang, his carriage is roofless, and it is transformed in Wulianghai with the partial box car of the car battalion, made into a carriage with the same width as the track, adding a protective plate on the other side, and the wheels are also replaced with the shape of the track, so as to make up for the dilemma of the lack of early carriages.

Don't look at the roughness of the change, it's easy to use this outside.

An army cannot pull hundreds of soldiers, carry so many goods, and the speed is slow, and Mongolian horse bandits are often encountered after leaving the customs...... They had just been annexed for a short time, and who knew who was in the vast grasslands? The flag army in the standard carriage stretched out the bird gun and sounded it, and it had to be able to kill people to scare the horse bandits away.

The outlaws of the nomadic tribes are the most unbearable, but if they can't hit accurately, in fact, even the flag army with the best shooting skills will be difficult to hit accurately when both sides are moving, and if they can't hit accurately, they can't scare the horse bandits at all.

Qi Jiguang's non-standard carriage is different, there is no seat in the car, but the barrel of the Franc cannon is stretched outward in a black hole, and the man on horseback and bow sees it from a distance and takes off his hat on horseback and salutes.

Exceptionally well-behaved.
