Chapter 98 Visiting the Second Blacksmith of Soto City

Montenegro Town.

In the valley where steel is smelted, several pottery jars as tall as two people appeared.

The coal waste gas produced by the steel smelting chimney is introduced into the pottery vat.

this day.

Ye Tian came over to inspect.

Amori, the president of the Blacksmiths Association, who has been fully responsible for the smelting tasks within the jurisdiction of Soto City, accompanied him.

Amori patted the pottery vat with admiration and said to Ye Tianda: "The workers who smelt steel in the valley said that the soot is too choking."

"Now that we have ceramic jars to filter the soot, the air around us is indeed much better."

Ye Tian pointed at the narrow and towering valleys around him: "The terrain here is narrow and the air is difficult to circulate. It is really not suitable to smelt steel here."

"It's just that for now, the enemy we face is powerful, and the steel smelting cannot be stopped, so we can only temporarily settle in such a valley that is easy to defend and difficult to attack."

Having said this, Ye Tian pointed to the pottery vat again and said with a smile: "These pottery vats are not just for filtering exhaust gas, but also for turning them into treasures."

Amory was surprised: "Isn't this choking exhaust gas produced by coal burning also a treasure?"

"Of course baby."

Ye Tian spent a lot of money to build pottery jars to produce sulfuric acid.

Both coal and iron ore contain a large amount of sulfur.

When sulfur is burned, sulfur dioxide is produced.

Sulfur dioxide is oxidized again to become sulfur trioxide, and sulfur trioxide dissolves in water to become sulfuric acid.

Sulfuric acid is the mother of all acids. Various acids can be prepared through sulfuric acid.

Acid is an important raw material for making smokeless gunpowder.

If you want to make bullets, you need smokeless gunpowder.

Unfortunately, Ye Tian did not have the most important catalyst in the process of producing sulfuric acid.

It can only be made using earthen methods such as pottery jars.

Ye Tian smiled and asked: "President Amori, have you ever heard of sulfuric acid?"

"I've heard of that thing." Amaury was full of contempt when he heard the word:

"This is all a trick played by charlatans."

"They first melted a small amount of gold into the acid water, and then put the copper coins in. After a while, the copper turned into the same color as gold."

"When I was young, I saw with my own eyes that someone used this trick to defraud people in Gengxin City. They defrauded a wealthy family into bankruptcy."

Hearing this, Ye Tiandun was interested: "President Amory, can you prepare sulfuric acid?"

"My lord, you are joking." President Amory shook his head: "This kind of sour water is the special skill of those in the world. How can it be spread easily?"

"I've only seen it before, but I don't know how."

Hearing this, Ye Tian felt a little unmotivated.

For Douluo, there are people who can make sour water.

Ye Tian was not surprised.

Douluo is a world of cultivation where alchemy is popular.

Refining alchemy is just a hodgepodge, and refining acid is not a strange thing.

In the ancient times of Blue Star, the production of acid was also discovered by alchemists who made alchemy.

It seems that we cannot place our expectations on outsiders.

Ye Tian shook his head, summoned a group of newly recruited craftsmen, pointed at the pottery vat and said:
"These pottery jars are used to make acid water."

"The first clay vat, used to filter coal stove exhaust gas."

"A second pottery jar in which saltpeter and sulfur can be ignited."

Ignited sulfur is used to increase the concentration of sulfur dioxide.

After the saltpeter is ignited, it will act as a catalyst to turn sulfur dioxide into sulfuric acid, but the efficiency is very low, but it is enough to produce sulfuric acid.

Even if Ye Tian talked about the principle for three days, even the craftsmen in front of him wouldn't understand it.

But the operation method can be explained clearly in a few words.

"The waste gas generated in the second tank is channeled into the third, fourth, and fifth tanks using cow intestines."

"Water vapor must be flowing through these three tanks without interruption! Eventually, all the gas will be collected into the sixth tank!" "Do you understand everything?" Ye Tian asked lightly.

"Understood!" Although the craftsmen were illiterate, they answered very loudly.

Without him.

It's too simple.

Just use cow intestines as a conduit to pass the combustion exhaust gas back and forth between these cylinders.

The craftsmen thought that the Lord of the City had summoned them personally, and that he might have some important tasks to answer.

Unexpectedly, it was just a job of cooking pots.

Ye Tian was extremely serious: "Don't touch the water in the sixth tank. It's extremely dangerous. Don't touch it even during transportation!"

talking.

Ye Tian took out a letter and handed it to Amori: "I have made it clear above about the dangers of acid water. Please tell me again."

"Yes." Amory bowed and accepted the order.

Ye Tian was still worried about this.

He sent two soldiers to keep watch.

After all, the corrosion degree of sulfuric acid is too great.

When the sulfuric acid production is completed, Ye Tian plans to demonstrate it to the workers so that they can see clearly so that they can protect themselves.

After inspecting Black Mountain Town, Ye Tian led Amori back to Soto City.

Today they have to do the second thing.

Invite Amori's apprentice, Wu Bing, to come out.

Wu Bing's home is not in Heimei Street.

But in the slums south of the city.

It was poorer than Black Coal Street.

Probably because Wu Bing also had to take care of his mother, so he had very little time for blacksmithing.

When Ye Tian came to visit, a pair of red couplets were posted in front of Wu Bing's dilapidated door.

Ye Tian took a look and saw it said: "Lotus flowers bloom with parallel stems, and orchids knot with the same heart."

Amori already knew about the existence of this couplet. When Wu Bing got married, he, the master, also gave him a generous gift.

But after following Ye Tian, ​​Amori still couldn't help but said:
"In the past two days, I just heard from Master Zhang Gongzhang that Wu Bing's marriage is your concern."

Ye Tian smiled without saying a word.

He knocks.

"Who is it?" A 1.8-meter tall man with messy hair opened the door.

When he lowered his head and saw Ye Tian, ​​who was about 1.4 meters tall and about nine years old, the big man was stunned.

But when the big man saw Amori behind Ye Tian, ​​he immediately said respectfully: "Master, you are here."

The big man hurriedly greeted a woman in the courtyard who was wearing a Luofu skirt and was washing clothes. Her eyes were full of doting and she said:

"Ting'er, come and meet our master."

"Hello, Master." The woman was gentle and virtuous, and stepped forward to greet Amori.

Amory shook his slightly rickety head and pointed at Ye Tian with a smile:
"You don't have to be polite to me. This is the Lord of the City. I haven't seen him before."

"City Lord... Your Excellency." Wu Bing's eyes widened and he couldn't believe Ye Tian's appearance.

But he still moved quickly and saluted Ye Tian: "I have met the Lord of the City."

The woman named Ting'er was a little frightened. She couldn't help but take a step back and looked at Ye Tian tremblingly.

"Ting'er, what are you doing?" Wu Bing looked puzzled.

Amaoli knew Ting'er's life experience, so he stepped forward to comfort Ting'er and said:

"Ting'er, I know that you and your elder brother are dependent on each other. He is the only relative in this world."

"But it is an indisputable fact that your eldest brother has participated in the evil forces and aided the evil forces."

"Don't worry, the Soto City Security Team is just sending your eldest brother to undergo one year of labor reform. There will be no risk to his life."
