Just when the little dog brother, the little stone dog and the flute dog yelled, "Ya ......", the three of them violently worked together, just pulled the big bucket to the edge of the well, who knew that they had a chance to rest and breathe, and the three of them fell into the well together with the big bucket one after another.

Fortunately, when the big bucket was pulled up, it fell into the well and poured a lot of water, not to pull them down to the bottom of the well, and at that time, it was not so fun.

Of course, if the water is good, even if the bucket is full and falls into the well, it will be fine, as long as you hold on to the rocks exposed by the well, and the weight of the large bucket in the water will be much lighter.

When Qin Guangming, Li Leiluo, Su Youjin and other old people in the small village ran to the well, Brother Little Dog, Little Stone Gouzi and Di Dog all showed their cute little heads in the well water, and laughed stupidly.

Fortunately, the three of them are very good in water, and there is nothing serious, just a slight injury.

With the help of Qin Guangming, Li Leiluo, Su Youjin and the elders of the village, they finally pulled up Brother Little Dog, Little Stone Gouzi and Di Dog safely.

Later, Qin Guangming, Li Leiluo and Su Youjin listened to the old man's explanation, and Qin Guangming and the others knew why there were so many people taking a shower together at the well tonight.

Because if the children of the small village want to go to the well to fetch water and take a shower, they must be supervised by the old people of the village, and there are few people, unless they go to bathe in the river of the village in the daytime, but now the river at the edge of the village has long been dry.

Then you can still take a bath, you can only come to the well in the village to draw water for a shower, the main reason is that if something happens to someone, it is good to have a care, so there will be so many people bathing by the well tonight.

But last time, Qin Guangming, Li Leiluo and Su Youjin also met, but there were not as many people as last time.

The children in the small village didn't take a shower for long, and they all dispersed one by one, and Qin Guangming, Li Leiluo and Su Youjin also took a shower casually, rubbed the clothes and pants they had worn for a day by the way, and went back to Village Chief Chen's house to sleep.

Time flies, and in the blink of an eye, a few days pass quickly.

In the past few days, Qin Guangming, Li Leiluo and Su Youjin have been wandering around the village, doing nothing anyway!

From time to time, instruct everyone or see how everyone grows vegetables, and if there is anything wrong, stand up and remind and discuss.

Seeing that the villagers in the small village were fine, he led the villagers of the small village who had nothing to do to go up the mountain forest to cut down some trees.

In the past few days, the villagers of the small village have planted all kinds of vegetables on the wasteland near the small village.

After a few days, seeing that everyone was fine, Qin Guangming arranged for everyone to start making soil saltpeter, and it would take a while for them to plant seedlings, and everyone was idle, plus Qin Guangming's status in the village was so high, the villagers in the village listened to him one by one.

First of all, Qin Guangming's first step is to teach the villagers of the small village how to find the nitrate, which is the most important and critical first step.

Early the next morning.

Qin Guangming, Li Leiluo and Su Youjin led the villagers of the village early to look for nitrate everywhere in the boundary of the village.

Whenever you see some old soil containing some small white particles like salt, or some soil surface showing yellow or white granular matter, it is nitrate soil containing saltpeter.

Where do you find these nitrates? Qin Guangming told the villagers in the village: "Mainly on the wall of the old house or near the thatched house, or near the hut of the cattle, these places should have the largest nitrate content, so let's look for it separately." ”

When the villagers heard this, they all scattered in all directions, and they all divided up and searched carefully.

It is also strange to say, this place of the small village is very strange, and the saltpeter can be said to be everywhere, and there are so many that it can be said to be a small village of saltpeter.

On the first day, Qin Guangming, Li Leiluo and Su Youjin led the villagers of the small village to dig half of the small village, and the sky was already completely dark.

As you can imagine, there are too many! The small village is not very big in the first place, just a dozen households, and you know the area you know.

The village really doesn't know what to do, it can almost be said that there is nitrate everywhere, and even there is a family in the village, a grass house is basically nitrate, there is no way!

Nitrate is really, really, too much! Needless to say, Qin Guangming, Li Leiluo and Su Youjin were tired of backache and leg cramps.

But it's getting late! Qin Guangming also had to ask someone to cover all the collected nitrate soil with branches or grain poles.

This is to avoid the volatilization of saltpeter in the nitrate, otherwise the saltpeter in the soil will not evaporate when the sun comes out tomorrow, and that will be hell.

With the efforts of Qin Guangming, Li Leiluo and Su Youjin leading the village, all the soil and nitrate in the village were finally dug up within two days.

If you want to dissolve the nitrate, you must dig a pond of nitrate on the ground, the size of the pool should be able to fit all the soil nitrate in the village, dig one meter deep, the wall of the pool should be inlaid with tiles, and the bottom of the pool should also be filled with tiles to avoid nitrate water seeping into the ground or other soil.

Then all the soil nitrate gathered in the village is poured into the dissolution pool, and the saltpeter in the soil is quickly dissolved by pouring clean water and stirring together.

Then it is to filter the soil, repeat the filtration several times, and be sure to filter the soil impurities.

After filtering the soil, the next step is to build a stove, and when a few large stoves are built, a large iron pot is set up, and a large iron pot is set up, and the saltpeter is boiled.

Pour all the dissolved nitrate into multiple large pots and boil, start to boil the stove hotter, wait for the nitrate in the pot to boil, then turn the furnace fire down, and slowly boil the nitrate water into a thick shape over low heat.

The key to this step is to judge the heat of boiling and when to stop boiling, which completely depends on Qin Guangming's experience and judgment, Qin Guangming has been boiling at home before, and he still has some technical experience.

Qin Guangming would take a small amount of nitrate from time to time and put it on the tiles to observe after it cooled down.

If it is solid, it means that the nitrate has been boiled, and the fire can be stopped, and after cooling, the saltpeter is done, but the saltpeter is yellow, but it can still be used to make gunpowder, and the problem is not very big.

After several days of hard work, Qin Guangming and the others finally made saltpeter, Qin Guangming, Li Leiluo and Su Youjin never expected that so much saltpeter could be boiled in the small village, so much that they couldn't estimate.
