Chapter 350
Lijin Manor.
In the morning, Su Chen and Li Tai came to Sun Simiao's residence.
"Hello, Master Sun!" Li Tai greeted Sun Simiao politely.
Although Li Tai was a prince, he still needed to greet Sun Simiao first.
"Old Immortal, I'm busy!"
"Haha, you came to me to ask how to extract sulfur?" Sun Simiao smiled after bowing to Li Tai in return.
"Old Immortal's calculation, that's it!" Su Chen admitted generously.
"This is not difficult. To extract sulfur, first use stone to refine coke. Then build a half-person-high charcoal kiln with a round hole on the top of the kiln.
Ignite the coke and put in the sulfur stone to burn it fiercely. When you see the yellow smoke floating up, cover the top of the kiln with an inward-rolled pottery jar.
When the yellow smoke dissipates, take down the pottery jar. The thing attached to the inner wall of the pottery jar is sulfur."
Sun Simiao explained the steps of refining sulfur one by one.
Su Chen nodded and asked Li Tai beside him: "Did you understand?"
"Sun Zhenren, how much coke and sulfur stone should be put in at a time?" Li Tai ignored Su Chen and asked Sun Simiao.
Sun Simiao thought for a while and said: "Five parts of coke and one part of sulfur stone."
"Thank you for telling me, Sun Zhenren. Qingque has made a note of it." Li Tai bowed his hands and thanked him.
"King Wei is polite!" Sun Simiao looked at Li Tai and nodded frequently, thinking to himself:
'This boy is really smart and eager to learn! '
"Hahaha, old immortal, you continue to be busy, let's go back and try." Su Chen achieved his goal, laughed and pulled Li Tai away.
"By the way, do you know how to make coke?" On the way back, Su Chen wanted to test Li Tai.
This was not the first time Su Chen heard about coke. When the system rewarded blast furnaces before, it also included the method of making coke.
"It's similar to the principle of charcoal. When the stone is smoldered to a certain degree, it becomes coke."
Li Tai nodded. He not only knew but also saw that the craftsmen in charge of making gold, silver and copperware in the Ministry of Works would make and use coke.
"Oh, that's good. You find someone to build a kiln to refine sulfur." After returning to the living room, Su Chen handed over the task of refining sulfur to Li Tai.
"Wait, what's the use of refining sulfur?
And the loud noise yesterday was clearly from the cement factory on the north side of the manor.
Tell me what happened!"
Li Tai grabbed Su Chen and let him go if he couldn't explain it clearly.
"Isn't sulfur used to make pills? I want to make a kind of elixir of immortality.
Don't worry, I'll give it to you first after it's refined."
After that, Su Chen shook off Li Tai and walked towards the study.
As for the explosion, Su Chen didn't mention it. He was afraid that the fat man would be obsessed with explosives.
If he is blown up by accident, it will be difficult to explain to Li Shimin.
"Asshole! Do you think I am a fool?" Li Tai cursed angrily.
However, he will still do what Su Chen tells him to do.
With a cold snort, he left to find someone to build a kiln to refine sulfur.
...
After lunch, Su Chen and Li Chengqian couldn't stand it anymore. Li Tai kept pestering them about the gunpowder explosion yesterday.
Before that, Su Chen and Li Chengqian agreed not to tell Li Tai about the explosives, fearing that Li Tai would be killed by the explosives.
Su Chen had no choice but to tell him.
Look, the three of them are now tinkering with making explosives.
"Fatty, when filling the gunpowder, you must not use metal objects to apply pressure. The gunpowder will explode when it encounters a little open flame."
Su Chen handed all the proportions of the earthen explosives to Li Tai, and now Li Tai is making the explosives.
And this time it's not a pottery jar, but a copper ball.
The copper ball can be filled with less than two kilograms of gunpowder.
"Remember!" Li Tai didn't care that Su Chen called him fat.
"Can this gunpowder blow up the copper ball?" Li Chengqian asked curiously. Su Chen used pottery jars to make explosives before.
"You don't understand this. The stronger the material of the gunpowder, the greater the power of the explosion.
After the gunpowder inside is ignited, it will produce high temperature and high pressure in a closed environment, and the internal air will gradually expand and squeeze. When the external material can't bear it, it will burst instantly, thus achieving the explosion effect."
Su Chen explained patiently, mainly for Li Tai to hear.
"By the way, has the kiln for refining sulfur been built?"
"You can try to refine sulfur later." Li Tai answered casually.
Su Chen nodded. Last time, he brought back sixty or seventy pieces of pyrite from Hua County, which was about one hundred and fifty kilograms.
I don't know how much pure sulfur can be refined.
"Alas! I made something as powerful as explosives, but the system gave me a useless reward.
What's the use of a 100-kilowatt hydraulic turbine generator? How can you build a dam without steel bars?
Besides, we haven't made any wires yet, how can we use the electricity we generate?
There are no light bulbs either! How do we insulate the wires?
It's totally redundant and a waste of time."Brother-in-law, why are you sighing?" Li Chengqian heard Su Chen sigh and asked in confusion.
Li Tai had just finished making a dynamite ball at this time.
"Li Tai, let me ask you, is that the only bronze that can be refined in the Tang Dynasty now?" Su Chen shook his head and turned to look at Li Tai and asked.
"No! The bronze you see every day is used to make some utensils because of its high hardness.
There is also a kind of refined gold copper, which is softer than bronze and is mostly used for jewelry and other ornaments.
Simply put, you can get gold copper by melting bronze again."
"Gold copper? Could it be 99.9% copper? That's amazing! In this case, the only problem left is the insulation of the wire!"
Su Chen silently remembered this matter, and after finding a way to insulate the surface of the wire, he would make the wire.
"Pack up, let's go to the study." Su Chen saw that Li Tai's explosives were ready, and stood up and said.
"Su Chen, let's go outside the manor and detonate the explosives!" Li Tai suggested excitedly while holding the copper ball bomb.
"Damn it, be careful, the gunpowder will also be detonated by external force.
Then the three of us will become immortals on the spot."
Then, Su Chen looked at the copper ball bomb and wanted to know how powerful it was. This time he planned to blow up the rocks.
"Take the telescope, let's go blow up the mountain!"
"Okay, okay, let's go!"
The Li Chengqian brothers became excited!
...
"My Lord, the Duke of Dai and his son Li Dejian have been waiting in the living room for a long time."
As soon as Su Chen and the other two walked out of the backyard, Zhang Long immediately came forward to report.
When the three of them entered the backyard before, they had told that no one was allowed to enter the backyard to disturb them, so Zhang Long had been guarding outside.
"Oh, the God of War is here!" Su Chen quickened his pace and walked towards the living room.
"Uncle Li, I'm sorry to have kept you waiting for so long!" Su Chen came to the living room to apologize to Li Jing.
"Haha, I just arrived not long ago." Li Jing stood up and bowed to Li Chengqian: "Greetings to the Crown Prince and His Royal Highness the Prince of Wei!"
"Greetings to my uncle!"
"Dejian, long time no see!" After Li Chengqian returned the greeting to Li Jing, he stepped forward and patted Li Dejian.
Perhaps because Li Jing was present, Li Dejian behaved very well.
"Greetings to His Royal Highness the Crown Prince and His Royal Highness the Prince of Wei."
Then, Li Jing looked at the strange copper ball in Li Tai's hand, "Your Royal Highness the Prince of Wei, could this be..."
Li Tai smiled and nodded, "Uncle came at the right time, we were just about to go..."
"I'll go get the telescope and talk about it when we get there.
Zhang Long, you go prepare the digging tools and a good horse."
Su Chen quickly ran to the study.
