PS: First update!

Luo Heng carefully explained the situation, and the contradiction between Lancado and Quisen made Satin also brighten his eyes.

Sardin agreed to Luo Heng's request, and Luo Heng talked carefully about the technical requirements with Satin, and Sardin also knew about standardization.

The standardized crossbow equipped by the dwarf kingdom has made many people shine, but it is good to mark it well, and it is very troublesome to set it up.

And this is listed as a top secret by the dwarf kingdom, Sardin wanted to ask before, but Luo Heng didn't take the initiative to say, no one would ask.

For privacy, this world is still relatively protected, of course, it is also possible that those nobles have too much dirtiness.

"Teacher, I will make the first steam cannon with you, and I will leave the rest to you later. After several hours of explanation, Sardin completely understood, and Luo Heng was also relieved.

"It's wonderful, it's a genius design. Satin exclaimed.

The machinery on the human side, not to mention that it has developed to the peak state, but compared to this world, it is much, much better, just take a pipe valve, there are many, many kinds.

Luo Heng uses some simple valves, such as on-off valves, check valves, and safety valves.

These things may be found on Earth, even on a pressure cooker.

But in this world, there is no pressure gauge, these things make Sardin's eyes shine.

Quisen came to the territory the next day, and brought several alchemists who were proficient in metal alchemy.

With the recipe, with the materials, the progress is accelerated all at once.

The first is to create a cannon that can shoot ~ fire, mainly for testing, and almost all of the whole process is done by Luo Heng.

Especially in the casting and polishing of parts, there will be many problems when the alloy is cast.

Temperature, mold, as well as grinding and polishing, etc., of course, Luo Heng made some tools by the way, these tools are made by nanorobots, and the accuracy can be said to be very high.

The barrel is also cast, because of the addition of magic materials, toughness, hardness can be said to have exceeded the standard.

This is where it is more convenient than on Earth, where it takes countless trials and turns in order to achieve a certain requirement, but here, as long as you add magic materials with the corresponding attributes, you will be fine.

The cast barrel still needs to be polished, Luo Heng did not use a grinding machine or anything, but used manual polishing.

Why?

Because there are many people, and this kind of cannon barrel does not need to be too accurate, but Luo Heng still underestimated the alchemist.

The alchemist has many ways to polish it, and Luo Heng doesn't care about it, and then there is a high-pressure pipeline.

The high-pressure pipe Luo Heng is cast in metal, and a high-pressure tank is installed just behind the barrel, although it looks a little weird.

The first finished product came out half a month later, and several dwarves led by Satin who participated in the whole process, several alchemists, Kuisen Luo Heng.

The diameter of the barrel reached two hundred and forty millimeters, the front of the barrel reached three meters, and the rear high-pressure tank reached one and a half meters, and the overall weight reached one ton.

This big guy looked very huge to Luo Heng, but in front of a human being who was as high as two meters and five, it was not very big.

Whew.

In a canyon in the back mountain, the flames of the steam engine made a whirring sound, and the high-pressure steam was sent into the high-pressure tank.

This steam engine is specially manufactured, pressure-resistant, and very tough.

On top of the steam pipes, there is also a pressurized pump, steam pipes, steam engines, and a high-pressure tank behind the gun pipes, all of which have safety valves.

Although there is a pressure gauge, but the safety valve is a thing, and it is okay to have one more.

"That's the shell. Luo Heng took out a metal ball, which was very heavy, about two hundred catties, after all, it was twenty-four centimeters in diameter, two hundred and forty millimeters.

"It's both a gasket. Luo Heng took out another piece of wood, which was also two hundred and forty millimeters, of course, strictly speaking, it was okay not to use this gasket.

But there is better, after all, the accuracy in the future may not be so high.

At a distance of 1,000 meters, 2,000 meters, 3,000 meters, 4,000 meters, and five kilometers in front of the barrel, several layers of wooden targets were already arranged one after another, and the thickness of each wooden target reached twenty centimeters thick.

"Brother Quison, you pull the switch. Luo Heng said.

"Good. Quison pulled the rope.

The reason why the rope is pulled is also for the sake of safety, of course, the rope pull is also a feeling.

Boom!

As soon as there was a dull ring, there was a dull sound in everyone's ears.

A wooden target a thousand meters away, there was an immediate sound.

Luo Heng and the others hurriedly stepped forward to check.

"Three thousand meters!" Soon an alchemist flew back.

"Three thousand meters of wooden targets were shattered. The alchemist said excitedly.

The range of three thousand meters is not nothing, but they are all magic weapons.

Although the steam cannon also uses magic materials, it does not use magic power in the later stage, as for the wood needed for the steam engine.

Hehe!

Wood is not worth much in this place, and no one wants a large ~ piece of primeval forest.

"It's a shotshot, and it's fifteen hundred metal balls in it. Luo Heng said.

Luo Heng took out a meter and filled it directly, and then poured it in.

At a distance of five hundred meters, a wooden wall target, like a fence.

Rumble!

Then five hundred meters away in the wall, somewhere directly punched a huge hole, and countless hollows scattered around.

"The length is eighteen meters, and the height is five meters. "Soon the range of the bomb was measured.

"It worked!" Quison exclaimed excitedly.

At the hearing that day, Quison was very angry, and the test was successful, and Quison was in a mood.

Luo Heng didn't care about the rest, Quisen got a steam weapon association, and developed a lot of versions, steam trebuchets are also under the jurisdiction of this association, as well as steam crossbows, steam cannons.

As long as the weapons related to steam belong to this association, these associations, along with the pesticide association, the steam engine association, and the textile association, all belong to the alchemy association.

Luo Heng hurriedly came to the Ice and Snow Fortress to build a steam trebuchet here, for which Kuisen also lent Luo Heng twenty craftsmen, mainly to make trebuchets.

Luo Heng was happy, and began to arrange it in the ice and snow fortress, so many trebuchets were mainly built on the mountain where the ice and snow fortress was located, so he had to build another cannon position on the mountain, and twenty magic giant crossbows were also established on the top of the mountain, which was actually a kind of slide rail, and the crossbow arrows were directly pushed on and then steamed.

The Dwarf Kingdom took out a lot of fine iron and gave it to Luo Heng for free, and the Dwarf Kingdom sent hundreds of craftsmen, and even their families sent them together.

"It's big. Luo Heng looked at the design drawing, a little weak, this investment is too big.
