Chapter 892

Dugu Feng, the magistrate of Jiulong County, was obviously an official.

Even if he didn't understand why he wanted the people in the city to scrape those white crystals, he conscientiously implemented it because Li forgot to worry that "this matter is related to the survival of Jiulong County".

So in Jiulong County, up to the old and down to Mengtong, they all carried baskets on their backs and squatted at the roots of thatched houses, pigsty and old houses to scrape those white crystals.

The people in the city complained about this. Who is willing to run to those dirty and smelly places and get these useless things.

What's more, now the sword of Damocles, a staff, is still hanging on the heads of the people. At this time, it's natural for the people in the city to complain about letting them do these unknown things.

At this time, Li Wangyou could not manage how to make complaints about those people behind him. He ran to nine county officials in Longxian, and ordered a nitrating pool to be extracted from the scraps of nitrate.

This method was also heard from the elders in the village.

Because of the hurry, the excavation of the nitrate leaching pool will make the good county government muddy everywhere.

Dugu Feng was ready to cry at this time. How could his good county yamen be directly ruined by the Huxian public?

The walls of the pool more than half a meter deep are built with bricks, and the bottom of the pool is smashed with wheat straw mud to ensure that there is no water leakage.

Dig a hole at the outside end of the pool and bury a small urn.

A small hole is made at the bottom of the pool, and a pottery pipe is installed to connect with the small urn.

When everything was ready, Li forgot to worry and ordered people to dig the nitrate soil, mix it with plant ash, put it into the nitrate leaching pool, step on it with their feet, and fill the pool with water.

The water in the nitrate leaching tank will take the nitrate out of the soil after seeping through the nitrate soil, and enter the small urn through the pottery pipe.

Drenching out crimson water is nitrate water.

After that, Li forgot to worry and ordered people to set up a large stove in the yard of the county government, directly moved out several large iron pots from the kitchen of the county government and began to boil nitrate.

This made Dugu Feng's face twitch, but he could only bear it silently.

Dark red nitrate water is poured directly into an iron pot and boiled over a high fire.

Until the bottom of the pot boiled white salt and the nitrate water boiled into a thick liquid, it was a success.

Li forgot to worry and ordered people to take these boiled salted water, put it into Tao Peng, and place it in a cool place to keep it carefully.

After the boiled nitrate water is cooled, white crystals are hung on and under the pottery basin, which is the refined nitrate.

When nitrate was extracted, Niu Wu and Dugu Feng were shocked.

Where did they expect that nitrate could be made from the soil scraped out by the thatched house, which completely subverted their cognition.

"Lang Jun, it's really nitrate! Can nitrate be produced in the toilet? It's really an eye opener."

Dugu Feng directly bowed to Li QIAOYOU and said, "my lord knows astronomy and geography. He really studies heaven and man! But my Lord still doesn't understand why he ordered me to collect nitrate, sulfur, charcoal and so on?"

Li forgets to worry very much. He smiles at Dugu Feng and spits out two words: "keep secret!"

Dugu Feng, the county magistrate, was speechless and looked at Li QIAOYOU with a sad face.

Niu Wu quickly grabbed his thigh to avoid laughing and being written down in the little black book by his "careful" husband.

In fact, he still doesn't know what Li forgetful worry wants to do. In Niu Wu's understanding, gunpowder is used to make explosive rods and fireworks. As for killing people with gunpowder, he can't think of it.

How gunpowder is made naturally needs to be kept strictly confidential. Li forget worry doesn't want such dangerous things to be spread all over the street.

In the original mansion, only the two brothers Niu Yong and Niu Wu knew how to make gunpowder. Li forgetful also told them again and again not to divulge half of it.

Now in Jiulong County, Niu Yong is not around. Others believe that Li forgetful worry can only summon Zhang Xuan and Zhang Xuan brothers and tell them to learn how to make gunpowder with Niu Wu.

Li forgot his worries about his own episode.

After repeatedly telling the three people to pay attention to safety and avoid using metal appliances, Li forget worry asked Dugu Feng to prepare a quiet courtyard for Niu Wu in the county government office and start gunpowder production.

In a little half a day, Niu Wu and his colleagues carefully ground sulfur, charcoal and nitrate into powder with a medicine mill, and carefully mixed them together according to the ratio taught by Li forgetful.

After making several kilograms of gunpowder, Niu Wu went to ask Li forgetful about how to deal with these gunpowder.

Li has long considered how to make these black gunpowder into murder weapons.

You don't have to think about making guns and guns.

If you want a student of e-commerce to know how to make guns, it can only be realized by the manifestation of the supreme old gentleman.

What's more, with the primitive level of metal smelting and metal processing in Datang today, Li forgets worry. It is estimated that he will have to ask the gods to help him carry another set of mechanical equipment from later generations before he can manufacture hot weapons.

This is a complete industrial system. It can't be as easy as written in the novel. It realized industrialization in Datang more than a thousand years ago.

However, although he can't make guns, Li forgets that he can also use these black gunpowder in other ways.

Making explosive bags is the simplest one.

In movies and TV dramas, the kind that often appears on the camera is wrapped like a quilt. In fact, it is also called group charging.

Spread the bulk powdered explosive in the middle of cloth or paper, wrap it like a bag, and then bind it with rope. A necessary explosive bag for killing and setting fire at home and travel is even done.

If you are a little crazy, and then bury some broken stones and broken tiles in the explosive bag, the effect will be better.

Li forgot to worry and asked Dugu Feng to send silk directly to guide Niu Wu to tightly wrap gunpowder in it, and then "accidentally" sprinkle some gravel into it.

The several catties of black gunpowder ground by Niu Wu and them were all wrapped in a four-way explosive bag.

"Lang Jun, what the hell is this? If the explosion rod is too big, how big a brazier do you need to order it?"

Niu Wu still thinks that Li forgot to worry about getting this thing. It's just a strange looking explosive rod.

Watching Niu Wu throw up and down a few kilograms of explosives as a toy, Li forgets to worry about the cold sweat on his back.

Paralysis!

This frightening bastard Niu Wu doesn't pay for his life. Do you really think that thing in his hand is just for listening?

"Stop!" Li Qieyou shouted loudly, which startled Niu Wu. The explosive bag in his hand almost didn't catch it and fell underground. Li Qieyou's heart almost stopped beating.

Although he also knew that black powder wouldn't explode even if it fell, who could say such a thing accurately?

If the several kilos of explosive bag in front of him explodes, there is no need to think about the consequences. Even the collection of the corpse can be avoided. He can only pray that God will let him cross again.

For Niu Wu, who almost scared himself to death, Li forgets worry. He can only kick him angrily, with a black face, motioning the Zhangjia brothers to hold the explosive bag and go with him.

He has to find a place to test the power of the explosive bag
