Stone Era: Restarting Civilization

The person who undoes petrification by his own power is called "Ishigami Senkuu".

Pan Changgong has personally experienced the feeling of being petrified. During petrification, although the body cannot move, the consciousness still exists.

The brain can still think, but if the brain wants to think, it also needs to consume energy, and it consumes a lot.

Turning into a stone without replenishing energy, but still being able to think, is in itself a violation of the law of energy conservation, the law of nature.

If it does not violate the laws of nature, it can only be explained that petrification itself is a kind of energy that can be absorbed by the human body, so people can still think after turning into stone statues.

Therefore, if someone is in the dark, his consciousness does not sink, and he keeps his mind active all the time, it is actually possible to rely on this kind of water to grind his kung fu, consume the energy of petrification, and finally get out of trouble.

It's just that it's rare for anyone to have such perseverance.

Ishigami Senkuu was an exception, and after waking up, he immediately knew how much time he had experienced.

When he was petrified, Ishigami Senkuu was thinking in the dark all the time, but he didn't go crazy. By counting every day, he confirmed that he woke up after 3700 years.

Ishigami Senkuu was 15 years old when he was petrified. He just finished high school. He was very obsessed with science since he was a child. He actively and systematically learned a lot of scientific knowledge.

Possesses strong mental arithmetic ability and is a genius.

After waking up, looking at the other petrified stone statues around him, he immediately realized his situation, and firmly wanted to rely on his own scientific ability to find a way to break the petrification, revive all mankind, and re-establish scientific civilization.

On the other hand, after Pan Changgong had learned his lesson, he did not choose those more practical strong adult men for the next resurrection object.

Instead, adult females are specifically chosen to be resurrected.

Although adult women are not as strong as adult men in terms of physical strength, they are more stable. Women are not as aggressive as men, and they are relatively less dangerous to Pan Changgong.

This time, Pan Changgong learned to be smart, and did not reveal to any of the resurrected people, including Chiba Xihe, the method of making the miracle water.

After the dozen or so traitors died, Pan Changgong revived a dozen newcomers, without exception, all of whom were female, and quite pretty.

In such a primitive ecological environment, women who are weak in strength are completely vulnerable groups.

At this moment, they were looking at Pan Changgong with admiration.

Pan Changgong was very satisfied with their attitude and confirmed the correctness of his current behavior.

"The toilet pit has been built, and it will be convenient for everyone to go there in the future. If you want to turn Mitiangong into a qualified fertilizer, you should regularly add a small amount of wood chips or wheat straw to Mitiangong. Remember not to bring Plants with leaves are thrown in. The purpose of this is to balance the carbon and nitrogen content in the rice field, and at the same time absorb the water in the rice field to prevent the growth of bacteria. You must stir regularly, and it can be used after half a year. Did you hear me clearly?"

"Understood, Master Pan." All the girls said in unison.

Human rice fields are a good thing. In addition to being used as fertilizers, they can also be used as an energy source.

When rice paddy is exposed to the air, it will react with aerobic bacteria and fungi in the air, and ferment rice paddy, so that it can be used as a fertilizer.

However, if rice fields are placed in a sealed container, anaerobic bacteria will grow, and the anaerobic bacteria will react with the organic matter in rice fields to produce methane.

Methane is combustible.

In today's oil-gas-free world, methane plays an important role.

However, relying on the accumulated rice fields to obtain methane, the total amount of rice fields needed is huge. The amount of the dozen or so people I have can only be used as fertilizer. When the population increases in the future, methane will be considered.

In the early stage of crop planting, for the purpose of feeding more humans, the main purpose is to ensure the quantity, not the taste.

Therefore, staple foods such as wheat and rice are temporarily less cultivated.

Potatoes, sweet potatoes and corn are mainly grown which are easier to survive.

Under the guidance of Pan Changgong, combined with the fertile soil left behind by thousands of years of evolution, a bumper harvest came in the first year.

It was precisely because of this bumper harvest that Pan Changgong used the water of miracles to resurrect many people, all of whom were women without exception.

The current Pan Changgong has been revived, with nearly a hundred people.

Because there is enough food in abundance, the uneaten food should be preserved to prevent it from rotting in vain.

In the past, Pan Changgong never considered food preservation, because he has always been alone, and it doesn't matter whether the food will be wasted, but now he needs to calculate carefully.

The reason why food spoils is mainly due to the existence of microorganisms.

All life on earth, including microorganisms, needs water in order to grow and reproduce normally.

So as long as the food is dehydrated, it can naturally inhibit the growth of microorganisms, so that the food can be preserved for a longer time.

Pan Changgong, who has a wealth of agricultural knowledge, ordered his subordinates to dry or air-dry the uneaten grain before putting it in the warehouse.

However, the progress of this processing method is relatively slow, and there is no problem if the amount of food is not large.

If the quantity increases, it will be inconvenient, and other ways to preserve food will need to be found.

That is to pickle the food.

Pickling also aims to eliminate bacteria and achieve the goal of preserving food.

But this requires a lot of salt or sugar.

The source of sugar is sugar cane and sugar beet, and it is too extravagant to use this method when it cannot be grown on a large scale today.

Gang Jing is close to the sea, and a large amount of salt can be obtained by drying sea water.

On the other hand, half a year after Ishigami Senkuu's resurrection, his childhood friend "Taiju Oki" from the same school also revived.

Taiju Oki was 16 years old before he was petrified. He was a simple-minded man with well-developed limbs.

With the cooperation of the two, Ishigami Senkuu also succeeded in inventing the miracle water by relying on his genius brain and rich scientific knowledge.

And in a crisis of being attacked by a weak lion, he used the water of resurrection to resurrect "Shishio Tsukasa", who is known as the strongest primate.

Shishio Tsukasa was 18 years old before Petrochemical, and lived with his seriously ill younger sister, in order to provide high medical expenses for his seriously ill younger sister.

Participated in many underground boxing competitions, and gradually became famous, with strong fighting experience.

Shishio Tsukasa killed a lion with one punch, successfully defusing the crisis.

However, precisely because of the appearance of Shishio Tsukasa, many uncontrollable results appeared in the sequel.
