Zhou Qingfeng attacked Broken Bridge City before, but although he returned with a great victory, the horses suffered a lot. After he came back, he thought about using mechanized power to replace the delicate horses that were difficult to serve.

Not many requirements, simple, durable, and cheap.

Arsey struggled for half a year and found a spider-shaped component of a prototype.

The road conditions in other worlds are poor, and the eight legs of the spider structure must have a better ability to move in the wilderness than horses. However, it does not run fast enough, and its defense can basically be called naked running.

In order to reduce the cost and facilitate large-scale production, Alsey removed the core magic array for permanently enchanting the assembly. In order to provide power, she also specially invented a magic steam engine that looks weird.

The steam engine is actually a machine for boiling water, but it is impossible for the rider to add coal to the boiler endlessly. Just as Zhou Qingfeng's altar of faith can provide a large number of magical gems, just choose a kind that can be heated as fuel.

The small boiler and cylinder crankshaft of the steam engine were brought from the real world by Zhou Qingfeng. After assembly, it became a smoky thing.

It was installed on the spider assembly as a driving force, and the entire machine was successfully reduced to 5,000 gold coins per unit. In comparison, the price of a heavy war horse was 200 gold coins, and the price of a sergeant was 50 gold coins.

"It's still too expensive. It would be great if each unit costs 1,000 gold coins."

Zhou Qingfeng was riding a spider in the Fuqiang collar at night, and his butt was hurt. "This thing is so ugly, and its reliability is still poor. I broke it twice after running around."

The magic steam engine is too large, which causes the center of gravity of the constructed spider to be very high, which makes it very easy to overturn when running. In addition, the machine is not mature and breaks from time to time and needs to be adjusted properly.

Arsey hummed twice to the owner's complaints, just pretending that he didn't hear them. She and Sophia thought about how to improve and create an item that had never been seen before, which was a great pleasure for Demonic.

Zhou Qingfeng got off the spider and rubbed his butt that was hurt, and specifically instructed Alce to make improvements to the suspension system.

"Jiying" leaned out from the side and said, "Why should the great master, a noble and wise monarch like you, be troubled by such things? As long as I am here, you will ensure that you are galloping on the battlefield and be brave and invincible."

Zhou Qingfeng glanced at him, "This flattery is too stiff today and it's not comfortable at all."

"Is that true?" "Jiying" fell into self-doubt, "This is what I just watched the owner test the spider's majesty, and I was inspired by a moment of thought, and I created it specially."

"You can shut up." Zhou Qingfeng knew how embarrassed he was just riding the broken spider, as if he had an epilepsy.

"Okay, master." "Jiying" lowered his head.

The maid was left to improve the spider in the laboratory, and Zhou Qingfeng went out and went to Fuqiang to lead another confidential area. When he moved here, the No. 4 Craftsman Area of ​​Harmony Village was moved here and many equipment were added.

Hanfeng City has always faced strong survival pressure, and the previous battle with Banshee Castle was not satisfactory. Zhou Qingfeng dragged his opponent into the "mud" with a different war model, which eliminated the war.

Considering it later, we must reflect on whether it is appropriate to continue using cold weapons to continue to use their own cold weapons?

The Panshi Battalion of the Cold City Infantry Regiment continued to walk the path of heavy infantry, but the other two battalions simply dropped their spears and heavy armor after expansion, because Zhou Qingfeng's manufacturing industry had touched the edge of the hot weapons and jumped over the flintlock and directly used a flintlock rifle.

The barrel and flintlock mechanism are easy to say, and the weight is only about one or two kilograms, and you can bring twenty or thirty sets from the real world every day. This just strengthens the confidentiality.

The buttstock is made of wooden and can be processed with a simple machine tool. The craftsmen in the ‘Zone 4’ can already assemble all components firmly.

The key is gunpowder. The chemistry of another world is somewhat different from reality. The fireworks used for hot weapons are simply ineffective in another world, which forces Zhou Qingfeng to find another suitable launching medicine formula.

This is just right for an alchemist.

Wizard Jason, who had previously made the "Missile Staff", had a confidential laboratory in Area 4. He led more than a dozen wizard apprentices to verify thousands of alchemy recipes copied from the "Gate of True Knowledge".

This laboratory looks ordinary, with more than a dozen ordinary compartments. The most important equipment is several high-precision balances, as well as various material purification passivation equipment.

Apprentices must carry out protection when doing experiments, so as not to accidentally die. Many alchemy formulas are powerful, or emit highly toxic smoke after explosion.

Alchemists are prone to making money and easily die of misfortune.

In the past six months, Jason has only verified more than one hundred formulas. It may be the next second, and maybe several years to find the perfect launcher.

Seeing the lord appear at the door of the laboratory, Jason, with a black face, spread his hands and said, "The situation is no different from last week. Most formulas that meet the requirements are toxic after explosions. A small number are either weak or very expensive."

The "Gate of True Knowledge" records the achievements of elves for more than 20,000 years. There are too many alchemy potions that can explode simply. But most of them are used to explode in the enemy, and very few are used to explode in front of one's own side.

"Is it useful 'scarab powder'?"

Zhou Qingfeng walked into the laboratory. Jason chanted the spell lightly and opened a revitalized safe. There was a small bottle in the box with light golden powder inside.

This thing comes from a peculiar insect. Its body is dried and ground into powder. If there is a little spark, it will explode. Although the gas after the explosion is choking, it is not toxic at all.

But this thing is very expensive, very expensive, and the cost of a round of ammunition is ten gold coins. The source is also very limited, and it is difficult to supply a large amount of demand, and even the daily training of the troops is difficult to meet.

"This thing can only be used in small quantities. Your infantry must be equipped with long spears and heavy armor." Jason said, "As for other recipes, I'm still testing them. I hope I can find something cheap and easy to use one day."

Zhou Qingfeng had to compromise on this, "Okay, it seems that my hot weapon can only go to the elite soldiers. Since every bullet is so expensive, it is too wasteful to use it to fight small soldiers."

"So what?" Jason felt something was wrong.

"So we have to match it with a rifled fine forged barrel, a zoomable sniper scope, and a magic-breaking pure gold warhead, which is specially designed to deal with valuable targets such as wizards and advanced knights from two hundred meters away."

Hujason was stunned. His eyes were once again focused on the bottle of light golden medicine powder, and he felt extremely chilled at the scene described by Zhou Qingfeng.

The enemy of Hanfeng City is in trouble, and the wizards hiding far behind the defense line are not safe.

After Zhou Qingfeng said that, he added: "Can that damn scarab beetle be raised manually? It is definitely not possible to rely on wild supply. We have to change our thinking about solving the problem."
