Bright Sword: Starting from the Improved Grenade

The blacksmith first asked an apprentice to pour the sulfur ore that had been broken into pieces aside into the sulfur incinerator.

Soon after being heated at high temperature, the sulfur ore began to change, and sulfur dioxide gas rose and entered the cylinder tower made of ceramic pots.

The remaining slag will face downwards and will eventually be poured into a pottery jar for storage.

After sulfur dioxide gas enters the ceramic pot, it undergoes a catalytic reaction with oxygen to become sulfur trioxide, which is then absorbed by water to form sulfuric acid.

"Add saltpeter."

The blacksmith, who observed the production of sulfuric acid through his goggles, quickly gave instructions.

The carpenter at the side did not dare to hesitate and immediately poured the prepared saltpeter into it.

Soon after heating, nitrogen oxide gas appeared in the cylinder chamber.

Then all the sulfur oxides, nitrogen oxides and oxygen produced in the cylinder body enter the cylinder tower together, and after multi-stage circulation evaporation, sulfuric acid is finally formed.

Looking at the white liquid dripping from the pottery jar, everyone present became excited.

"Is this a success?"

"It should be successful!"

An apprentice couldn't help but reach out to touch it out of curiosity.

"Bang! You're risking your life! Didn't the factory manager tell you that sulfuric acid is highly corrosive?"

The blacksmith slapped the apprentice on the head.

"Hehe, I was too excited just now, and my brain couldn't react immediately."

The apprentice touched his head and grinned.

"Okay, stop talking nonsense, hurry up and get some in the pottery jar and show it to the factory manager."

The carpenter urged.

Using a small brick and tile factory, Li Yuncai and his team produced many small ceramic jars, which are specially used to store things, and are now coming in handy.

After a while, the blacksmith took the pottery jar and carefully filled it with some sulfuric acid.

"Just watch here. I'll show the sulfuric acid to the factory manager."

Having said that, he ran out quickly, which forced several other people who also wanted to go and claim credit to stay.

"Flattery."

The blacksmith trotted to the door.

"Slow down, Master Li. Don't spill it."

Li Yuncai's tone was very relaxed. It was obvious that they had already seen the transparent liquid flowing out of the pottery jar at the door.

"Director, deputy director, look, it's a success."

Li Tie handed the small pottery jar to Zhao Tianyang with excitement.

Zhao Tianyang took the pottery jar, walked outside the factory, picked up the pottery jar and poured it into the weeds at the door.

With a "hiss" sound, a few wisps of green smoke suddenly rose from the emerald green grass at the door.

The small patch of grass turned yellow and dry visibly, and the grass that was in direct contact with sulfuric acid even turned pitch black, apparently carbonized.

"Hiss~~~~~"

Li Tie and Li Yun took a deep breath. Now they finally understood what danger Zhao Tianyang was talking about.

If this thing touches a person, it would probably melt the bones.

"See? This is the power of chemicals. Will you dare to be careless in the future?"

Zhao Tianyang glanced at the two people beside him and reminded them.

"Yeah, I don't dare anymore. I don't dare anymore."

The two men shook their heads repeatedly, especially Li Tie, who looked scared when he thought about how his apprentice had just wanted to touch him with his hand.

"Okay, let's leave it at that for today. How do you guys eat dinner?"

Because there was no electric light, people in the arsenal went off work when the sun set and went back to work when the sun rose.

Hearing this, Li Yun looked at the sky and said, "Director, we usually eat the same as usual, cornmeal and steamed bread."

"But since we live in the mountains, we have set up some traps near the factory, and sometimes we can catch some rabbits or something, which can be used as a meal."

"It's not convenient to get in and out of the mountains. It would be best to start a vegetable garden near the factory and raise some chickens or something."

"Okay, I'll ask them to open up a piece of land when they have free time."

Li Yuncai nodded.

"Okay, then you guys go cook. I'm going down the mountain first. Call me if you need anything."

The performance of the blast furnace at the foot of the mountain is still unknown, Zhao Tianyang has to go back and take a look.

"Slow down, Director."

Li Yuncai shouted to Zhao Tianyang who turned and left.

After Zhao Tianyang was completely out of sight, he turned around and said to Li Tie: "Everyone performed well today, and each of you will be rewarded with an egg."

"okay."

Li Tie walked excitedly towards the newly built open-air stove. Halfway through, he suddenly remembered something and ran back to ask, "Deputy Director, do you want me to cook one for you, too?"

"No need. Today I am mainly rewarding you for successfully refining sulfuric acid. It has nothing to do with me."

Li Yuncai waved his hand, eggs are still very precious.

Except for Zhao Tianyang, who could eat one every day to replenish his body because Li Yunlong had specifically instructed him to, other arsenal personnel could only eat it after they had made meritorious services.

When Zhao Tianyang came down the mountain, the sun had just set and the workers at the arsenal were eating around the iron smelting furnace.

"Director, you're back."

Seeing Zhao Tianyang coming back, Chang San quickly stood up and scooped him a large bowl of corn paste.

Zhao Tianyang took the bowl and started eating with everyone around the iron furnace.

Not to mention that the weather is getting colder now, especially at night when the temperature in the mountains drops several degrees. Staying next to the iron smelting furnace is both warm and well lit.

After taking two gulps of corn paste and picking up a pickle from the bowl, Zhao Tianyang asked, "How is it? Is there anything wrong with the blast furnace?"

"no problem."

Chang San pointed to the annealing furnace next to the iron smelting furnace and said, "The smelted iron has been transferred to the annealing furnace. After the annealing is completed, it can be shaped and cut."

"Then let's all work hard today, work overtime, and knock out the shell casings."

"no problem."

Iron smelting is different from sulfur making. After the iron is put into the stewing furnace, it must be used in time, so they can only work overtime today.

After dinner, the workers began to forge iron under the light from the iron furnace and blast furnace.

As the workers hammered, a 400 mm long solid cylinder was hammered out.

"Get on the lathe."

Chang San and his men used tools to lift the cylinder and ran into the arsenal.

Along with the roar of the machine, the cylinder was drilled and hollowed out, and a blank of a cannon barrel appeared in front of Zhao Tianyang.

"The next step is polishing and finishing, but we can do that tomorrow. Today we will process all the steel in the annealing furnace."

Looking at the steaming barrel blank in front of him, Zhao Tianyang said excitedly.

"Director, you should take a rest first. It's considered a success now anyway."

Chang San suggested.

"You don't need me to watch you guys, just rest together when you're done."

I don’t know if it was because Zhao Tianyang was there, but after two hours of busy work, the steel in the stewing furnace was completely consumed.

In exchange, they received six gun barrel blanks and thirty artillery shell blanks from the arsenal.

"get off work."
