The biggest difference between the people of the Great Wilderness and the people of the earth is that because the environment in which the people of the earth live is not as bad as that of the Great Wilderness, the concept of region and the consciousness of fame and fortune were born prematurely.

In the Great Wilderness, the first concept of human beings deep in their bones is to live, and the second concept is to be able to eat.

Only someone can provide a safe living environment and feed them, even if they have a revenge for killing their father, they can be resolved in the Great Wilderness.

As for Wang Village, the powerful Black Armor Army can even hunt second-level creatures, and they have already proved their strength with facts, so they can naturally give the village attached to him a safe haven.

As for being full?

Wang Village can be said to be the village with the most abundant food in the Great Wilderness, and there is no one left. In the eyes of other villages, Wang Village is like having a granary that can never be eaten, and when you finish eating today, you will wake up tomorrow morning and find that the granary is full again. Naturally, it can meet the needs of the tribesmen for food and clothing.

When these two conditions are met, Nawang Village, in their eyes, is heaven.

To be able to live in a safe and secure Wang Village, which people in the Great Wilderness do not want to?

Therefore, when the body of the Snail King was transported back in a high-profile manner, although the threshold for joining Wang Village was raised a lot and the conditions were much harsher, there was still an endless stream of tribes who chose to swear to join Wang Village.

Wang Hao handed over these things to Wang Long to count and deal with.

As the old patriarch of Wang Village, and the elder with the highest prestige in Wang Village at present, it is very suitable to deal with such a matter.

As for those tribes who had already joined Wang Village and applied to send the Black Armor Army to help eradicate the second-level creatures that endangered their village, they were handed over to Wang Hu to deal with.

Although every time you destroy a second-level creature, you can get a lot of gains.

But every time a force is sent, it also means that there is a possibility of casualties for the Black Armor Army.

Wang Hu's bold character who regards all the Black Armor Army as brothers will definitely carefully assess the danger of every dispatch, so Wang Hao can rest assured that he will hand over the Black Armor Army to him.

As for Wang Hao, when he returned to the village and divided the school into three, divided into a junior class, a middle school class and a graduating class, he went to dig a manure pit.

The new school not only details what needs to be taught in each class divided into different levels, but also gives two sets of school uniforms in summer and winter for each child who comes to school for free.

With the improvement of textile technology, the twine is getting thinner and thinner, and the linen cloth can be thinner and more delicate.

Compared with the linen cloth that pierced the hands as soon as it was touched, the current linen cloth is much smoother, and even if you wear it on your body, it will not prick people.

Then some key parts that are not wear-resistant are decorated with soft animal skins after nitrate, even if they are worn by children, they are not afraid of hurting their bodies.

The development of science and technology needs to be taken step by step.

In the previous life, the earth was able to make white and smooth paper, and it was possible to make clothes out of linen that felt no different from silk, and it was not made all at once.

It is the result of generations of exploration and continuous improvement.

Although there are still too many flaws in the school, in general, it is still developing in a good direction. And Wang Hao believes that as long as he is there, sooner or later, the school in Huacheng will become a symbol of the spirit of the entire Great Wilderness.

The things in the academy can't be done overnight, but there is one thing that Wang Hao has held back to the point where he can't help but do it.

That's right, it's the digging of the manure pit mentioned above.

The minerals of the Great Wilderness are abundant.

Whether it is oil or copper and iron minerals that will be needed in the future, you can find them.

The tribes of ten miles and eight villages around Huacheng all came to Wang Village to exchange daily necessities, so in addition to collecting money and workers, Wang Village also received one thing, and that was the news.

Whether it is news about the nearby landforms, or news about the territory of high-level creatures, Wang Cun accepts it.

It's just that the news received by Wang Village is the most expensive, and the most things that can be exchanged are news about minerals.

The people of the Great Wilderness don't know the role of various minerals, but how can Wang Hao not know.

The matter of a rich mine and a province is not a legend, even a rich mine and a rich Wang Hao have seen it.

Just like the small desert countries that were rich because of oil in the previous life.

There is a lot of news brought from all directions, and when Wang Hao carefully screened it, he found that there was a lot of news about minerals in the Great Wilderness.

Copper and iron ore are not uncommon, and gold and silver mines are also heard of.

But what made Wang Hao entangled was that from beginning to end, he had never heard of the existence of nitrate.

To make gunpowder, it is impossible to lack nitrate.

And without gunpowder, even if Wang Hao has a system, it is impossible to develop hot martial arts.

Without hot weapons, how can you match an enemy like a dragon in the future, do you rely on a black iron ballista?

In fact, what Wang Hao didn't know was that nitrate is usually divided into miscanthus nitrate and fire nitrate.

Fire nitrate, on the other hand, is extremely soluble in water. Large-scale mines are only possible in places that resemble desert environments where it does not rain for several years.

The tribes that come from all over the world do not live in desert areas, although they cover a wide area.

Therefore, they naturally couldn't bring Wang Hao news about the fire mine.

And Wang Hao doesn't know much about these things, so of course he doesn't know that the places where there may be fire nitrate mines nearby, only the desert where Zhao Village is located, and the rest of the places have no hope at all.

Since the knowledge is insufficient, Wang Hao can only use stupid methods to make up for it.

Wang Hao's gunpowder dream, because he failed to find nitrate, can only build it on the toilet.

In the early spring, the toilet built of adobe has some white powder in the corner of the wall.

Those white powders are nitrate, but unfortunately, the yield is too low to be used on a large scale.

Therefore, if Wang Hao wants to get a large amount of nitrate to make gunpowder, he must build a nitrate field.

The principle of nitrate is very simple, that is, the use of water purification bacteria to turn organic matter proteins and the like into ammonia, and then the use of nitrifying bacteria to oxidize ammonia into nitrate, and finally the use of plant ash to provide potassium ions to purify potassium nitrate.

This nonsense is all something that Wang Hao doesn't know which book he has read before, because of its tongue-twisting and difficult to understand, but Wang Hao remembers it.

The water purification bacteria and nitrifying bacteria mentioned above belong to aerobic bacteria.

In the toilet, the poop is very viscous after accumulation, which is not suitable for their growth, so the amount of nitrate in the toilet is not too much.

Nitrifying bacteria are afraid of light and can be easily killed by bright light.

They do not reproduce fast and at the same time prefer oxygen and high temperatures.

Therefore, when these things were recalled by Wang Hao, he had specific ideas for the construction of the nitrate.
