Bet on it!

Cai Yu straightened his chest and said.

The only thing that can be used militarily is charcoal, which can be used to burn the enemy, but the effect of charcoal on fire is not as good as that of oil.

She really couldn't think of what these three ordinary things could do.

Very good!

Guo Jia smiled and groaned: "Girl, if you lose, what will you do?" ”

For some reason, he likes this sister-in-law very much.

"Whatever you want!"

Cai Yu also let it go.

Anyway, I am cheap, and this guy has taken advantage of it.

If he can really defeat Zhang Niujiao's army of 100,000, even if she is allowed to obey Guo Jia, it will be nothing.

As for the Taishan goat family, from the beginning, she had no intention of marrying it.

Anyway, Guo Jia is here, let him solve it.

"There's character, I like it!"

Guo Jia gave a thumbs up.

It is said that this is what he admires most about this little sister-in-law.

Afford to put it down.

It's a material for big things.

"What if you lose?"

Cai Yu asked rhetorically.

"How could I lose?"

Guo Jia smiled slightly.

Sulfur saltpeter charcoal is the raw material for the manufacture of black powder.

As a later agent, he was proficient in the manufacture of all types of explosives, and was even better at assembling explosives from ordinary things.

In this day and age, it's easy to use what you know to make some black powder.

However, given the chemical technology of this era, the purity of the materials required was limited. It's hard to make some fine gunpowder, but it's not a problem to make some crude black powder.

Although it is only some crude black powder, it is still very advanced in this era of cold weapons.

"Girl, you'd better hope I win, otherwise if I lose, Zhongshan will be finished, and your sisters will be finished. It's fine to fall into the hands of a person who pities the fragrance and cherishes the jade, but if it falls into the hands of those murderous Yellow Turban thieves......"

Cai Yu couldn't help but shudder.

If Guo Jia really loses, their sisters are really finished.

It's better to hope that he wins.

But this girl thought about it and fell for this guy again.

It's not a fair bet at all.

"Guo Jia, you bastard, you lied to me again!"

Cai Yu couldn't help but reach out and twist it on this guy's arm a few times.

Ahhh

Guo Jia couldn't help but scream a few times, and it attracted everyone's attention.

"Taishou-sama!"

Seeing Guo Jia walking in with a woman, they all stopped.

"No need to be polite!"

Guo Jiaqiang endured the pain, waved his hand, and continued: "Everyone continue!" ”

When everyone heard Guo Jia say this, they picked up the work in their hands and continued to do it.

These craftsmen are another harvest of Guo Jia's trip south.

Everywhere he went, Guo Jia sent people to recruit craftsmen from all over the country who could burn, mine and cast, and promised a lot of money.

At the end of the Han Dynasty, the status of craftsmen was low, and most of them couldn't fill their stomachs, so they couldn't come when they heard the call of Zhongshan Taishou and had enough to eat?

As soon as he came and went, Guo Jia recruited more than 100 craftsmen.

After solving Liu Bei, Guo Jia immediately transformed the backyard of the Taishou Mansion into a workshop and settled these craftsmen here.

This is a valuable asset, and Guo Jia will count on them to dominate the world in the future.

"Lord Taishou, Miss Cai Er!"

A young man greeted him, it was Zhao Yun's brother Zhao Shan.

Zhao Shan didn't have the ability of his younger brother Zhao Yun, and he didn't read much, but he was very serious about his work, and Guo Jia also did his best and let him be in charge of this workshop.

Seeing Zhao Shan come out, Cai Yu let Guo Jia go.

"How's this time going?"

Guo Jia asked in a low voice.

Zhao Shan took out a bamboo slip and said loudly: "This month, 5,000 catties of saltpeter and 5,000 catties of sulfur realgar were collected from foreign merchants. His own workshop burned 5,000 catties of charcoal. ”

In fact, as early as when Guo Jia promoted border trade, he began to collect saltpeter and sulfur.

After all, compared to other explosives, black powder is still relatively easy to make.

Saltpeter and sulfur are very common minerals, and as long as they pay for it, many merchants will send it to their doors. Charcoal can be fired by itself.

The only technical bottleneck is the two steps of purification and frying.

As for the deposit, Guo Jia did not think about creating high-purity chemical raw materials with the productivity of this era.

For him, that's pretty much it.

Very good!

Guo Jia nodded.

Zhao Shan seemed to remember something, turned around and took out a clay pot and put it in front of Guo Jia.

"This is something that has been purified and fried by several masters according to the will of Lord Fujun, and Lord Fujun has seen it."

Guo Jia reached out and picked up some powder, sniffed it, and nodded with satisfaction.

It seems that the craftsmen of this era are still very good.

Although the methods provided by Guo Jia are all simple methods, these craftsmen still make good purity and grind very finely.

Black powder has already taken shape.

Not bad!

Guo Jia was determined.

"How many raw materials can be produced in a day?"

Zhao Shan groaned slightly.

"It's about 100 catties, but if you work overtime, you can have 200 catties."

It's too slow!

Guo Jia thought for a while and said, "Pass on the official's order to recruit skilled craftsmen in the city, separate the production steps, and increase the intensity of production." In addition, the final mixing and mixing step must be done by a trustworthy person, pay attention to safety! ”

Brother Zhao Yun has always been loyal to Guo Jia, and Guo Jia is also relieved to hand over this core technology to him.

What is this?

Cai Yu looked at the jar of black powder in surprise, and seemed to be a little pungent and asked.

"Girl!"

Guo Jia said with a smile: "This is a good thing, whether you can repel Zhang Niujiao depends on it." ”

"That's it?"

Cai Yu looked incredulous.

Seeing that her sister-in-law was a little unconvinced, Guo Jia smiled and said, "Okay, let's see its power with our own eyes." ”

As he spoke, he weighed a certain amount of black powder, put it in a small jar, and pounded it tightly with a stick.

Guo Jia took a piece of oil, invaded the straw rope, mixed a little gunpowder into it, and inserted it into the jar.

A simple version of the mine was made.

The two rode to the outskirts.

Guo Jia kept his subordinates far away, buried the mines in the mound with his own hands, and left the fuse.

"Girl, cover your ears!"

Guo Jia turned around and ordered.

Why?

Cai Yu was puzzled.

"If you want to cover your ears, cover your ears."

Guo Jia said impatiently.

Although Cai Yu was a little unhappy, she still covered her ears obediently.

Guo Jia lit the fuse with confidence, and then ran back with Cai Yu quickly.

He had already found cover.

The two covered their ears, and there was no movement for a long time.

"Guo Jia, what the hell are you doing?"

Cai Yu was a little upset.

Guo Jia was also a little stunned, it stands to reason that the fuse should burn out at this time, why doesn't Mao explode?

After another while, Cai Yu couldn't help it anymore and slowly walked out of the bunker.

"I'm going back!"

She was already a little disappointed in Guo Jia.

At this moment, Guo Jia saw a large amount of black smoke suddenly rising from the direction of the mine.

Be careful, girl!

Guo Jia hurriedly threw Cai Yu to the ground.

A loud bang was followed by a powerful shockwave.
