Bright Sword: Starting from the Improved Grenade

“Ding, ding, ding…”

"Fall, fall, fall..."

At six o'clock in the morning, when it was still light, Zhao Tianyang was awakened by the noise outside the arsenal.

That’s right, for so long, Zhao Tianyang has been living in the warehouse with the workers of the arsenal.

"what happened?"

Zhao Tianyang opened the warehouse door with sleepy eyes, and saw soldiers from the new regiment outside constantly throwing rails on the open space outside the arsenal, making a clanging sound.

Zhang Dabiao stood in front of a pile of railroad tracks at the arsenal, directing Li Yunlong to reverse.

It’s a pity that this tricycle does not have a lifting function for the bed, otherwise Li Yunlong could have directly poured out all the rails in the car.

"Brother Tianyang, I hope I didn't disturb you."

Seeing Zhao Tianyang coming out, Li Yunlong quickly jumped out of the car.

"It's okay, I'm just getting ready too."

Zhao Tianyang looked at the rails that were about to pile up into a small hill and said, "Are these the results of last night? That's a bit too much!"

"Hey, it's not much, it's nothing. We still have a lot of things we haven't brought back."

Li Yunlong said with regret: "It's still because of my lack of experience. Who knew that the rails could be pried up so easily?"

It seems that this time it will be smooth. Thinking of this, Zhao Tianyang came to the pile of rails, picked out one that looked pleasing to the eye, and knocked it hard with the hammer he had just taken out of the warehouse.

"Dang~~~~~~~"

A loud sound woke Zhao Tianyang up.

"Well, 99%, it's a rare item."

Zhao Tianyang put down the hammer with satisfaction.

"How about it, okay."

Li Yunlong came over with a smile.

Seeing Li Yunlong's excited face, Zhao Tianyang asked: "It's a good thing. Tell me what you want me to make?"

"Of course it's a cannon. The railroad tracks you mentioned can be used to make cannons."

"No problem. I'll give you a list later. As long as you prepare all the materials listed above, I'll make it for you right away."

Zhao Tianyang agreed verbally, but in his mind he was quickly thinking about what kind of cannon could be made with this kind of railroad track.

"Great."

Li Yunlong suppressed his desire to jump up, rubbed his hands and asked, "Don't forget the tanks, you promised me."

"Okay, no big deal."

The main problem with converting cars into tanks is the tank tracks and the tank cannon, which cannot be solved. Now that we have rails, it can be manufactured with some difficulty.

"Good brother, you are really my good brother!"

Li Yunlong felt that the whole night's hard work was worth it. The rewards were very gratifying. Cannons and tanks were things he had never dared to think about before.

However, it is too early for Li Yunlong to be happy now. In the future, the gasoline for tanks alone will be enough to cause him trouble.

However, looking at Li Yunlong whose face was about to break from laughing, Zhao Tianyang thought it would be better to tell him later, and let him be happy now.

If you want to build a cannon, the first thing to worry about is the steel problem, and the second is the shell problem. With the rails, the problem of the cannon itself can be easily solved.

The problem facing Zhao Tianyang now is the artillery shells.

If you want to get a powerful artillery shell, explosives are an issue that you cannot avoid.

When it comes to the choice of explosives, Zhao Tianyang chose the classic TNT explosive, also known as trinitrotoluene, which is produced by the reaction of benzene and concentrated sulfuric acid.

As for the source of benzene, Zhao Tianyang chose the relatively simple "coalization process".

Through coal chemical projects such as coal gasification or coal tar processing, a mixture containing benzene is obtained, which is then separated and purified.

As for concentrated sulfuric acid, it is very simple. Zhao Tianyang plans to directly draw on the wisdom of his predecessors and use the "cylinder tower method" to produce it.

“It’s still very difficult.”

Looking at the paper with the required raw materials written on it, Zhao Tianyang felt a little distressed. He didn't know whether Li Yunlong would curse him after seeing it.

Facts proved that Zhao Tianyang was overthinking. Li Yunlong had no idea what Zhao Tianyang wrote on the paper, what it was for, and where to get these things.

"What the hell are these? Apart from coal, I can get them. Where are sulfur and zinc? I have never heard of them."

Li Yunlong looked at the paper full of words with a sad face.

Hearing this, Zhao Tianyang pondered for a moment and said, "As for sulfur, you can ask those merchants who sell coal."

"Pyrite is usually found in coal mines, but zinc is not needed for now. Zinc is only added to prevent corrosion and rust."

"Good idea. In that case, I'll go try it first."

With that, Li Yunlong left the arsenal.

Zhao Tianyang found Li Yuncai and prepared to start large-scale construction. Whether it was the preparation of concentrated sulfuric acid or coal chemical process, special equipment was needed.

Especially since sulfuric acid is poisonous, if it is not handled properly, he is afraid that all the people in the arsenal will be wiped out.

...................

Qinshui Coalfield is the largest Late Paleozoic coalfield in Shanxi Province, with a total area of ​​24,800 square kilometers. It is one of the largest coalfields in Shanxi Province.

It is located right between Taihang Mountain and Luliang Mountain.

Li Yunlong's target this time is Shili Township in Qinshui County, where there is a Huaping coal mine, which is said to have the background of Yan Laoxi, the third concubine of his second uncle.

"Are you Shopkeeper Li?"

In the Huaping Coal Yard, a short young man with a dog-skin plaster on his head was holding a small teapot and looking casually at Li Yunlong who had just been brought in.

Li Yunlong put his hands behind his back and looked around without paying any attention to this man.

"Yes, this is our shopkeeper."

Zhang Dabiao pointed at Li Yunlong and introduced him.

"Wow, that's quite a big score."

The short young man muttered something in his heart, but considering that Li Yunlong was wearing a long gown and had a terrifying aura, the short young man didn't know what to say and could only look at Zhang Dabiao.

"I heard from Sandengzi that you want to buy coal?"

"Yes."

"The coal we have here is all anthracite, and it's very expensive!"

"We don't mind the price, we just want good quality."

"it is good."

The short young man was delighted: "One ton of coal costs six dollars, starting at thirty tons."

"No problem, we can ask for a hundred tons, and the little yellow croaker will pay for it."

At this time Li Yunlong spoke, and the short young man was very happy as soon as he opened his mouth.

"That's great. Let's talk about when you want it. You still have to pay the advance."

"Don't be happy yet, I want something else."

"what?"

The short young man looked at Li Yunlong in confusion.

But Li Yunlong did not say anything, but glanced at the thugs surrounding them in the room.

Seeing this, the short young man thought for a moment and waved his hand at the thugs: "Can you tell me now?"

"Pyrite, do you dare to sell it?"

Li Yunlong said lightly.

"Hey, what else am I supposed to be?"

The short young man's performance was a little beyond Li Yunlong's expectations.

Normally, the raw materials for making sulfuric acid are sensitive items no matter where they are, but this person seemed a little disdainful.

"Just buy pyrite, why are you pretending?"

The short young man scoffed at first, then took out a notebook and looked at it: "There are two tons of pyrite this month. Do you want it? If you want it, I'll give you two small yellow croakers. No bargaining."

"Row."

Li Yunlong was stunned for a moment, then quickly agreed.

"Okay, then it's settled. Just give the deposit."

The short young man closed the notebook and said bluntly.

"this......."

Li Yunlong and Zhang Dabiao looked at each other, somewhat unresponsive.

The main reason was that they were just trying to find the way this time and they didn't take any money at all. Of course, the most important thing was that they didn't have that much money.

"You don't have any money, do you?"

The short young man narrowed his eyes slightly, revealing a fierce look.

"Yes, yes."

Li Yunlong quickly took out a gold watch from his arms. He had taken it out from the arms of a Japanese officer during the last ambush.

"We'll use this as a deposit first, and we'll bring the rest of the money in three days."

The short young man took the gold watch and looked at it: "Good stuff, it's settled. I don't want to know why you buy pyrite, but we are not responsible for delivery, you have to figure it out on your own!"

"no problem."

This is better so they don't have to cover up.
