Zhao Yuan's vigorous propaganda finally mobilized the men and women of the entire Zhaojia Village to work together to produce the wonderful products that the Zhao family needed.

Of course, the management of the Zhao family is also very good, both hands must be grasped, both hands must be hard, while collecting the feces and urine of the people in the entire village, they are also buying another thing: rapeseed oil.

It is estimated that the Zhao family's idea is to do it if they want to do it, so they directly purchased several truckloads of oil from Fang County.

Liu Yuanshan also knew about what happened to the Zhao family for a long time. Compared with the Zhao family's staring at him, he is also staring at the Zhao family, although the core secrets are impossible for both parties to obtain, but some things on the surface can't be hidden from others.

For example: When Zhao Yuan bought feces and urine in Zhao Wangzhuang, he almost scared Liu Yuanshan to pee.

Nima! This dog surnamed Zhao doesn't want to extract fire nitrate and then make gunpowder, if that's the case, it's really a bit of trouble!

He has a few small coins in his hand, and he has also been appreciated by Wang Xiucai and Li Zheng and others locally, but the Zhao family is a behemoth in Gushan Town, and their family is thousands of times stronger than Liu Yuanshan in terms of connections and heritage.

However, fortunately, the second news reached his ears, and Liu Yuanshan was immediately relieved.

The Zhao family began to buy rapeseed oil on a large scale......

My brother, it's okay to buy canola oil, is it possible, they want to make soap?

But who told him that the main material of soap is rapeseed oil + feces and urine?

After thinking about it for a while, Liu Yuanshan almost squirted two feet away with a mouthful of water.

I bought a large amount of rapeseed oil some time ago, and scavenged as much feces and urine as possible from the villagers' homes, didn't the Zhao family suspect that the main ingredients of my osmanthus soap were these two things, right?

"I'm ...... poof" Liu Yuanshan laughed again, smirked stupidly at the corner of the wall, and said to himself inexplicably: "I said, the gunpowder manufacturing technology of the Ming Dynasty is generally in the hands of the East and West Factories, even if the Beijing camp or some Liaodong soldiers participated in the extraction and firing, but they will not figure out the entire process of making gunpowder, and the Zhao family naturally cannot get the perfect formula of gunpowder, so it is very unlikely that they collect feces and urine to make fire, and it is possible to make osmanthus soap." ”

But why do you use feces and urine to make osmanthus soap, you are so talented, do you know it?

Knowing that the Zhao family did not buy feces and urine to make fire nitrate, Liu Yuanshan was much more relieved.

The Zhao family doesn't make fire, but his firepowder already has eyebrows.

With the arrival of spring, the weather is gradually getting warmer, the mountains are full of spring flowers, and the heavy clothes on the body have been taken off.

Many people think that extracting fire nitrate from feces and urine is an incredible or miraculous thing, and some even think that it is a fantasy. It's not as amazing as it seems.

In fact, whether it is animal feces or human feces and urine, there are a large number of incompletely absorbed proteins and some organic matter, which are exposed to the air and will be purified and decomposed again by water purification bacteria, and the protein amino groups in them will be decomposed into ammonia ions.

Ammonia is of course not nitrate, the decomposed ammonia will be continued by another bacteria in the air, and then the nitrifying bacteria will oxidize the ammonia into nitrate ions in the nitrate pool.

Whether it is feces, urine, plant ash, or even soil, there are large amounts of potassium ions.

Potassium ions react with nitrate to form potassium nitrate, which will adhere to the coarse sand at the bottom of the nitrate pond after natural drying and precipitation, which is actually fire nitrate.

If you want to extract potassium nitrate, you need to start with these coarse sands.

Liu Yuanshan built several nitrate ponds according to the tips of the divine book, poured all the feces and urine on the coarse sand according to the operation method, and then covered the top of the feces and urine with dry plant straw, because both water purification bacteria and nitrifying bacteria are aerobic bacteria, and they also like a cool environment.

As long as the ventilation is satisfied and not exposed to the sun, it can continuously produce fire nitrate.

After the nitrate pond was built, there were people who were busy sending feces and urine to it all day long, and after more than a month, the urine was evaporated and splashed, splashed and evaporated, back and forth several times, and a thin layer of white frost finally appeared on the coarse sand.

Liu Yuanshan knew that most of this thin layer of frost stains were potassium nitrate, but there were at least 20 percent impurities, and it would take a lot of effort to purify them.

Although it takes a lot of work, there is no high-tech technology, and it is not difficult, just troublesome.

Braving the stench, Liu Yuanshan also had to come to the scene in person and command the people to start the work of extracting fire nitrate for the first time.

First of all, he brought a dozen or so people to the place where the nitrate pond in the col was located, and at the same time brought two super large iron pots, a pile of pottery, and two bags of carrots.

After arriving at the nitrate pond, Liu Yuanshan divided two people to go to the nearby mountain stream to fetch water, and the five people went down to the nitrate pond to remove a layer of feces on the sand, and then shoveled up the sand with an unpleasant smell and made it into a pile, which was several thousand catties.

As for the other three, two large iron pots were erected on the slightly flatter ground.

"Wash the sand, let's go!" Liu Yuanshan waved his hand, distributed one mask to each person who had been prepared in advance, put it on to cover his mouth and nose, and then said to everyone: "Put the sand in the bucket and start washing the sand!" ”

Washing the sand is better than washing off a layer of hoarfrost on the sand!

Liu Yuanshan asked people to fill only half a bucket of water in each wooden barrel, then stuff half a bucket of sand, stir it in the bucket with an iron rod for a while, control the rancid water in it, and scoop it into a large iron pot.

There was a lot of sand, the container was very small, and the stirring was very slow, so the whole work of extracting the nitrate was also very slow, and after filtering out a large iron pot of rancid water, half an hour had passed.

Liu Yuanshan didn't care about being tired, looking at a large iron pot full of water, and a smile appeared in his eyes.

The first step is finally completed.

The second step is to boil nitrate.

Although it hasn't started yet, Liu Yuanshan already knows that this second step must be a very difficult step, not to mention how long it takes, just the smell that comes out of the boiling process, hehe!

However, it still has to be dry, regardless of the taste.

"Burn the fire!" Liu Yuanshan gave an order, Song Qiu took out the flint and lit the match, and the raging fire burned instantly, but the uncomfortable journey had just begun.

Sure enough, after boiling for more than ten minutes, there was a "zizzle" sound in the cauldron, and a wisp of pure white smoke rose from it and drifted into the air, and the imaginary smell finally came to the face. (To be continued.) )
