The second update!

After the design drawings were completed, Luo Heng began to get busy, first determining the location of each trebuchet battery, and then opening a road on the mountain to build the battery.

The road does not go into the mountain, but is mined directly in the mountain arm.

The nanobots came in handy again, cutting the stone directly, and then sending the orcs to carry the stone away, the stones that could be used, and these stones could just be used as ammunition for trebuchets.

On the other hand, Luo Heng also has to make the key component of the trebuchet, which is to convert the steam power into the power to pull the trebuchet.

It's not very complicated, but it's not that simple.

It is a whole set of things, molding, smelting, casting.

Because it is dispersed, all some places can only use things like winches, and manpower can be used as power.

"Steam as a power is not good, it should be a steam engine to drive the air compressor. Luo Heng also found that because the pipeline was too long, the steam was easily cooled, and all Luo Heng could only use air, so the requirements for the steam engine were relatively low.

At least there is no trouble with steam as pressure, and there are many high-pressure air as power machines, such as air cannons and the like.

The long air ducts had to be buried, otherwise in the event of a war, it would be troublesome to break it.

There are a lot of things, some cyan grasslands can already be seen on this side of the orc wasteland, and unconsciously, more than a month has passed, and the fort has been successfully completed, and the fort is particularly strong.

In addition, some of the various parts of the trebuchet were also manufactured, which were all scanned by Luo Heng to ensure that there were no dark diseases.

With giants present, assembling these trebuchets is like having large machines, and can perform verbal commands.

The assembly was fast, and three trebuchets were mounted on a single casemate.

"I really don't have a steam cannon to work well. When Luo Heng saw this steam trebuchet, he felt a little out of class.

But Luo Heng is not a murderous war maniac, what Luo Heng has to do is first and foremost to deter the enemy.

"Hulk, are you ready? Luo Heng shouted.

The steam trebuchet is going to be tested, and the Hulk as a loader, because the auto-reload is somewhat unrealistic, the layout of the main turret.

"Ready, Your Majesty. Hulk shouted.

"Alicia, are you ready? Luo Heng asked again.

"Ready. "Alicia is going to try it out for herself.

"Walker, pay attention to the target area. Luo Heng shouted loudly again.

"Okay. "Walker is in the valley below.

"Let's go. Luo Heng opened the air valve.

Whew!

The high-pressure gas drives the piston~, and the piston ~ drives the flywheel.

The flywheel drove the winch, and the trebuchet that stood tall was quickly pulled down.

Hulk had already picked up a rock, and the trebuchet was putting ammunition in a leather bag with a piece of wood underneath it, and Hulk saw that the leather bag was approaching the wood, and immediately put the stone in the leather bag.

"Okay!" Hulk shouted.

"Hair ~ Shoot. Alicia pulled a handle in front of her.

Call!

With a bang, the arm of the trebuchet suddenly ~ bounced up.

After the trebuchet's arm returned to its position, it triggered the winch and was pulled down again.

Good!

Hair~!

Hulk and Alicia simply cooperated, and they scored eight stones in one minute, and the other orcs on the lookers were also shocked.

Orcs are warriors by nature, and the frequency of this trebuchet has never been seen before.

"Very good!" Luo Heng carefully checked the loss of parts in each part and found that there was no problem.

"Continue assembling. Luo Heng said.

With the help of dwarf craftsmen, dwarven craftsmen, and alchemists from the Alchemy Society, three hundred and twenty-one large trebuchets and two hundred and thirty small trebuchets were assembled in half a month.

Luo Heng didn't care much, and hurried to the Magic Holy City, where the Steam Weapons Association under the Alchemy Association held a large-scale drinking party to promote steam weapons.

Originally, the time to witness with Langcado had already arrived, but Quison struck first and invited people from various empires, kingdoms, and principalities to witness the power of the steam machine.

Of course, the travel expenses are at your own expense, that is, Luo Heng, so that you have the opportunity to take the free magic airship, and those who follow Luo Heng are also people from the Alchemy Association.

Hundreds of trebuchets have already begun intense training, humans, dwarves, gnomes, orcs, half-elves, all of them.

Of course, the orcs are mainly responsible for carrying ammunition, and the giants are the overseers, and the dwarves and humans are basically marksmen.

"Duke Cheney, I have a question for you. "The alchemist of the Alchemy Association admires Luo Heng very much, Luo Heng's invention seems to have little value.

But every invention brings great benefits.

Some time ago, the pesticide toxicity test of the pesticide association has been completed, four pesticides, two ground insecticides, two underground insecticides, for pesticide residues, the pesticide toxicity test has ended.

And in thousands of acres of experimental fields have been tested, and the toxicity test of various organisms is carried out, and the toxic side effects on humans and livestock are very small.

The surrounding nobles where the test site is located have already placed orders for next year, and the total number of orders exceeds 200,000 mu.

"No problem, I still have this confidence in the mechanical aspect. Luo Heng nodded in agreement.

"Duke Cheney, can this steam engine be used on a ship?" The alchemist's name is Tony, and he mainly refines magic crossbows.

"That's okay too. Luo Heng nodded, the steam engine is on the ship, of course it can be used.

However, the wood of this world has never been as durable as coal, so the ship needs to be well designed.

However, Luo Heng prefers the internal combustion engine, but the fuel required by the internal combustion engine is also a problem.

"And Duke Cheney, do you still have any research on this?" asked Tony, his eyes lit up.

"Tony, the investment required in this aspect of the ship is too great, and the storm is huge, there are many factors to consider, and there is no energy for the time being, Tony, do you have any good ideas?" Luo Heng asked.

"The Holy See has long wanted to expedition to the Dark Continent, but there has never been a ship capable of sailing the far seas. Tony explained.

"So the Dark Continent has a higher level of magic than ours?" Luo Heng asked in surprise.

Indeed, when Tony said this, Luo Heng suddenly discovered that in terms of navigation, this continent is simply a blank.

"There is only one ship in the Dark Continent that can sail far away, and it is refined with the bones of demonic beasts, and we know very little about the detailed situation. Tony shook his head.

"So what do you mean?" Luo Heng heard Tony say this, and asked, Luo Heng was very unsure about shipbuilding, why is the ship so complicated?
