Walking through the corridor beside the hall, the two of them came to the courtyard behind the hotel.

The courtyard has only one floor, most of which are guest rooms, and the rest is used as a kitchen and warehouse. Rennes did not look around and followed Zoltan into a courtyard. Judging from the decoration of the house, it should be Zoltan's own residence. It was cleaned up, but no other dwarves were seen.

Zoltan opened a room with the key, and there were a lot of things piled up inside, which looked like a utility room.

Renn watched Zoltan push away the cabinet against the wall, and a downward staircase appeared behind him.

"Come down."

The dwarf did not explain much and took the lead in walking down the ladder.

Ren hesitated for a moment and went in.

The stairs were not long, and soon they reached the end, and an empty basement appeared in front of them.

Several gas lights lit up. Rennes was quite surprised when he saw it clearly. It was much larger than he expected. It was nearly one hundred square meters in area and three meters in height. It didn't feel narrow and stuffy at all. It could no longer be called a basement.

However, Renne's attention was attracted by the mechanical equipment around him.

A machine like a machine tool is placed in the middle of the basement. It looks thick and bulky and a bit old, but it is well maintained. Various connecting gears and flywheels are polished and shiny without any rust. The machine tool is connected to a tall boiler and obviously uses steam power.

“Steam car bed!”

Renn recognized it at a glance, but felt it wasn't right.

This machine is very complex, not just a single lathe. It seems to have functions such as cutting, forging, planing, milling, grinding and extrusion. It is like a pieced together universal machine tool. In addition to the steaming car bed, there are many other tools around, such as forgings, grinding wheels, etc., and various metal materials and parts are piled in the corners of the wall.

Zoltan saw Renne's expression and said proudly: "This is my private workshop."

Renn asked curiously: "Boss, are you a mechanical craftsman?" He had previously guessed that Zoltan was an alchemist, so he sold alchemy materials.

"It's barely true."

Zoltan shrugged, "I used to be a blacksmith in the clan, but my skills were very poor. Later, I went to the Empire to learn machining, but I had no interest in making swords and weapons. Now I am a gunsmith."

As he said that, he showed off the pistol on his waist and slapped it twice.

Renn had never heard of a gunsmith, but he could also guess that he was a craftsman who specialized in making soul guns. No wonder he saw many parts such as barrels and springs in that pile of metal materials.

"I was really sleepy and someone sent me a pillow."

Renn was very surprised. His plan was to confirm whether it could be made into gunpowder first. If possible, then find a way to make a gun.

There are many craftsman workshops under the "Steam and Machinery Union" in Longshande City, which sell all kinds of weapons and can also customize metal parts, as long as you can afford the money.

His previous idea was to customize firearm parts in batches in different craftsmen's workshops and then assemble them by himself, but the overall cost is definitely very high, so he had to get some money first.

Now that he saw Zoltan's workshop, Renn immediately had a new idea.

If you can borrow this workshop, do it yourself, and use the mechanical structure diagram in your mobile phone to assist, you can save a lot of money and quickly make a gun.

Zoltan walked to a wall and raised his hand and pressed it on it.

Several silver lines appeared on the wall, forming a door, and then opened inward. When this door was opened, it made a dull sound with the ground. It was obviously very heavy and seemed to be made of a complete stone, which ordinary people could not push open.

"This is a magical sect!"

Renn was stunned for a moment. It was the first time he had seen the Magic Gate, but what was even more surprised was that Zoltan seemed to trust him very much and was not afraid of being leaked at all.

This also made him feel alert. Will Zoltan have other plans?

Zoltan seemed to have guessed Renn’s thoughts and said indifferently: “I didn’t make this magic gate, including this basement, was found before I bought the hotel. There was actually no particularly valuable thing here, it was the place where I store alchemy materials. Many people who traded with me have come in.”

"Stop being slow, do you still want to buy alchemy materials?" Seeing that Ren was still hesitating, the dwarf was a little impatient.

Renne didn't think about it anymore and had to walk in.

The secret room behind the Magic Gate is not big, only more than twenty square meters, and the walls are all flat stones. The whole room seems to be hollowed out from a huge rock, and is airtight. The only light source in the secret room is the gas lamp held by Zoltan's hand. Because his hands are shaking, the lighting is very unstable.

Rennes secretly turned on the camera and turned up the brightness in his field of view.

Several rows of wooden racks are arranged indoors and are divided into hundreds of small grids, with various materials placed inside.

Zoltan raised the gas lamp to illuminate the wooden stand and said, "My alchemy materials are all here. I have used them a lot recently and sold a lot. Before I could replenish them, please check what you want to buy and tell me."

"Okay." Renn nodded.

There are hundreds of kinds of materials here, and they are complex in various types, mainly from various ores and powders, as well as some treated plant branches and leaves, as well as some strange shapes, which may be materials from living creatures.

Rennes was immediately in a little trouble, and he didn't recognize most of these materials.

He remembered the recipe of black gunpowder, but he didn't know how to say those three ingredients in Orion, and he couldn't tell if there was any here for a while.

However, there are some things that are very easy to recognize, such as alcohol and graphite, which may be useful. Renn took them down and put them on the table. He continued to search, his eyes falling on a glass jar containing a kind of black particles, dark and very familiar.

"Is this black powder?"

Renn stepped forward and opened the lid. He smelled a scent of gunpowder and was overjoyed. He was thinking about preparing it himself, but he didn't expect that there was a finished product.

"Boss, what is in this jar?" He pretended not to know the black gunpowder and asked casually.

Zoltan walked over and took a look and replied, "This is fire sand. It was used by our dwarves to make musket bullets a long time ago, but the power is too low and it is not easy to preserve. A lot of smoke will appear when shooting, so it has been replaced by phlogiston and is now useless."

Ren was very convinced after hearing this, that this was black gunpowder.

It turned out that the dwarf had discovered black gunpowder long ago, but it was not used on a large scale and was eliminated by Phosphimon.

Rennes had heard of phlogistin before, the main material used to make soul gun bullets, which can ignite explosions like gunpowder, but require soul power to stimulate. He immediately understood that it was precisely because of the existence of phlogistin that the Alan Ershi world did not continue to study more powerful gunpowder.

In fact, the power of black gunpowder is not small, but the dwarf has not developed the most accurate formula, so he quickly gave up.

However, this can of fire sand is probably not useful, and it is not powerful enough.

Renn thought about it and decided not to hide it from Zoltan, saying, "Boss, I want to buy some fire sand for research, and also need a recipe for its preparation and sufficient raw materials. I wonder if you have it?"

"I'll look for it."

Zoltan did not ask Rennes what he wanted for fire sand. He walked back and forth several times in front of the wooden rack. He quickly took three or four kinds of materials and introduced: "Fire sand is made of volcanic loess, charcoal powder and bitter ice. I will write it to you later."

Renn recognized immediately that volcanic loess is sulfur, and bitter ice is saltpeter, and he also remembered the names of these materials.

After that, he didn't buy anything else and asked Zoltan to make up the price.

Because these materials are common, not precious, and not large in quantity, Rennes bought them only after paying 100 copper lisots.

Before leaving the secret room, Renne's eyes accidentally swept across the ground and found strange marks under some wooden frames, forming complex figures, but were stuffed with dust, not obvious. If he hadn't increased the brightness of his vision, it would be difficult to see the existence of these marks.

But he didn't care too much and followed Zoltan away from the secret room.

Close the magic door, Zoltan glanced at Renn holding the alchemy material and said, "If you want to do alchemy research, my alchemy table can be loaned to you for a few days, so that you won't burn my hotel with fire sand upstairs."

While speaking, he pointed to a table in the corner of the basement with many glassware on it.

Rennes naturally wanted to do so.

He not only wanted to borrow the alchemy table, but also wanted to borrow the entire workshop and use the steam machine tool.

"Thank you, boss." Renn smiled embarrassedly, "I still want to borrow this lathe, is it OK?"

When Zoltan heard this, his eyes widened and his beard curled up.

Renne quickly added: "I can pay."

Zoltan's expression eased, and after thinking for a while, he said reluctantly: "It's okay to pay." He stretched out five thick fingers and said fiercely: "There are 50 copper licorices a day, and the coal and materials consumed are calculated separately. If the tools are damaged, you have to compensate according to the price."

Renn calculated the remaining money and could last for more than ten days. With his own operating ability, he should be enough to create a gun.

If you fail, you have to find another way out.

In order to avenge, he gritted his teeth and nodded in agreement.

Zoltan walked around the workshop, counted the existing materials and left.

Rain didn't want to waste his time, so he immediately went to the alchemy table, familiarized himself with the set of glassware, and began to prepare black gunpowder.

He had read a book about weapons and ammunition in the library before. The book not only included the development process of gunpowder history, but also the production methods of various types of ammunition.

The easiest one here is black gunpowder. He was very impressed by it, so he clearly remembers what the best proportion formula is.

In fact, black gunpowder is not the first choice. Rennes still remembers a method of using solvents to make smokeless gunpowder. It is more powerful and not difficult, but there is no raw material here, so it can only be second-class.
