PS: Strive for more tomorrow, the matter is basically over.

"Cheney, are you telling the truth?" asked Quison.

"Of course. Luo Heng nodded.

"I want Lankado to lose face and become the laughing stock of the union. Quison stared at Luo Heng.

"No problem, but I need some materials. Luo Heng nodded.

"No other requirements?" Quison couldn't believe it.

Luo Heng opened his mouth and said: "Dear Brother Kuisen, you think too badly, you think like this, I am very sad, you wait, I will go and get the sample I made." ”

Luo Heng left, and Kuisen was looking forward to it.

What samples there are, nothing is there, it's just an idea, Luo Heng decided to use the same fire ~ as a cannon barrel.

This is where the nanobots come in handy, and soon a palm-sized steam engine was built, which was then connected to a high-pressure tank, and then a steam cannon that was only ten centimeters long.

Of course, this is just a demonstration, and it magnifies that magic materials are definitely needed, especially in terms of pressure, Luo Heng also prepared some metal balls.

After a delay of half an hour, when Luo Heng took out a sample from a delicate wooden box.

"Oh my God, that's so accurate. Quison couldn't help but exclaim.

"Brother Quisen, please see, it's just a steam engine, this is a high-pressure tank, it stores high-pressure gas, this is a connected pipeline, my little thing, it's very powerful. Luo Heng opened his mouth to explain.

This is actually the same as the steam air pump used, and the high-pressure tank also needs insulation equipment, otherwise after the steam is cooled, it will be water.

Luo Heng directly put a small candle in the small steam engine, and soon the barometer showed that there was air pressure.

Ten minutes later, the gas gauge on the high-pressure tank also showed that a certain pressure had been reached.

"Brother Quisen, see clearly. Luo Heng took out a small piece of wood, and then put it in the barrel along with the metal ball, and stuffed a little wool.

"Brother Quison, see no, this can be aimed in any direction. Luo Heng pointed the muzzle downwards and demonstrated.

Then, five meters away, a wooden board was placed, and there was a layer of iron sheet on top of the board, which was of course very thin.

Luo Heng opened the air pressure valve.

Burst!

A bang.

Sonor!

Then a crisp sound.

Quisen immediately passed, and then exclaimed in disbelief: "The god of magic is above, how is this possible!"

The iron sheet was pierced, and the metal ball was deeply embedded in the wooden plank.

When the cannon was made, it didn't actually have much power, because the air tightness was not good.

Later, after the wooden plug was used, the power was several times greater.

Of course, this also has a lot to do with the accuracy of nanobot manufacturing, which can be said to be a standard that the original artillery cannot reach.

"This can hit five thousand meters at the farthest distance, can you imagine such a thick one, and then there are thousands of metal balls in it ~ shoot ~ out?" Luo Heng asked.

"Just like you used in the Stronghold?" asked Quison.

"It's different, this is the unique geographical environment of the dungeon using a steam engine, think about it, as long as there are hundreds of such things, what will the dungeon be like?" Luo Heng asked.

"Cheney, aren't you going to apply for this at the Magic Guild?" asked Quison.

"No, I think it's better to work with the Alchemy Society. Luo Heng said with a smile.

"No problem, what materials do you need?" Quison is very confident in this steam cannon, such a small model has such power, so much bigger?

"Very well, I'll write to you right away. Luo Heng nodded, and then wrote a lot of materials.

Kuisen looked at the material written by Luo Heng, and did not say anything.

When Luo Heng finished writing, Kuisen opened his mouth and asked, "Are you planning to arrange this in the Ice and Snow Fortress?"

"No, I'm going to set up two hundred large trebuchets and three hundred small trebuchets in the Ice Fortress. Luo Heng shook his head and said.

On the orc side, Luo Heng didn't plan to fight, but he also had enough strength, and he could imagine the rapid projection of two hundred large trebuchets, which everyone had to consider.

As for this kind of cannon barrel-like firing ~ firing method, Luo Heng felt that it was still used to deal with those monsters, and the underground creatures were the best, and a surprise could play a great role.

"We only have two months, no problem, right?" asked Quison.

"I can't guarantee this because I don't know when the materials will arrive, and I need a place to go. Luo Heng said.

"I'm looking for a place, but it's a little far away, it's a relatively large monster exit, and a lot of monsters rush out every year. Quison spoke.

"I'll make it here, and you can assemble it yourself, of course, it's best to send someone to learn how to operate it first. Luo Heng said.

"I went back immediately. When Kuisen heard this, although there were a lot of materials, and when Kuisen heard Luo Heng's explanation just now, he knew that the materials of the hundreds of trebuchets were also in it.

Luo Heng came to Sardin and Harding's side, there were already more than a dozen dwarves here, and as soon as Luo Heng opened the door, he heard Satin's roar.

"Are you stupid, look at what you're fighting?" Luo Heng saw that Sardin was teaching a new apprentice.

When Sardin saw Luo Heng, he immediately shouted to the dwarf apprentice: "Beat eight thousand times, one less, I'll beat you." ”

"Teacher!" Luo Heng saw Sardin walking towards him and immediately stepped forward.

"Cheney, do you need a weapon?" asked Sardin.

Sardinia thinks it's so wonderful, there is enough wine, there is enough ore, and there are enough disciples to forge if you want to forge and mine if you want.

"No, teacher, I would like to ask you to abbot a project, a project in cooperation with the Alchemy Society. Luo Heng said.

"Well, tell me about it?" said Satin with interest.

"It's your specialty, teacher, mainly forging some metal parts. Luo Heng said.

Luo Heng took out the drawings he had drawn temporarily, mainly to improve the high-pressure gas tank and cannon barrel, and there was no need to change the steam engine.

As for the steam pipes, this difficulty is relatively high, because these pipes have to withstand huge pressure, so the requirements for quality are very high.

After reading it, Sardinia said: "The data of these materials are not easy to achieve. ”

"Teacher, there is an Alchemy Association, but I heard that the Alchemy Association has a lot of compound metal formulas. Luo Heng said.

Luo Heng also has no way, the pipeline production is complicated, the project period is very long, and there must be a lot of follow-up orders, at least it is much cheaper than equipping the magic crystal cannon, and the power is enough to use.

But Luo Heng still has to face the threat from the orcs, of course, some people say that nanobots can, yes, but what about energy?

"Will the alchemy demon allow us to use it?" asked Satin in a heartbroken voice.
