Stone God Qianku wants to open up wasteland, because now the population is large, and wheat is obviously not enough. Because the appetite of primitive people is small, and the appetite of old humans is big, strong men can eat very much, and it is best to have meat every meal.
good.
However, land reclamation is obviously not that simple. The first is water source. Farmers all need water, but there are no water conservancy facilities. All water is taken from the lake. The fields near the lake are fine. The farther away from the lake, the higher the land reclamation cost.
Large. Because there is no irrigation water conservancy, the cost of land reclamation will be extremely high because manpower is needed to carry water.
Another problem is water accumulation in the rainy season. Farmland is not only afraid of less water, but also afraid of too much water. When there is too much water in the rainy season, if there is no drainage, the crops will also die.
Secondly, there is the damage caused by birds and insects to farmland. In the past, sparrows were ranked among the four pests because sparrows competed with humans for food rations and because sparrows damaged farmland.
The more land there is, the weaker the monitoring is, and the less likely it is to prevent birds from damaging crops. Anyone who has planted fields, or even vegetables, knows that in the mature season, birds fly around in swarms.
The scene there was extremely dark, and the sparrows were the most conspicuous among them.
Therefore, clearing wasteland is not as simple as Ishigami Senku thought. Of course, he has invented iron tools, so using shovels to dig canals for drinking water and using iron tools to cultivate land can also increase the speed.
It took humans tens of thousands of years to enter the agricultural society, tame cattle and horses, master the laws of fertility, and learn to drill for water conservancy. Before the emergence of water conservancy facilities, the harvest of the fields depended entirely on God's will. More or less water was beyond human control.
of.
Dulan discovered that after coming to this era, the farming gene in his body seemed to have awakened, which is called a clear-cut approach. Sure enough, farming is an instinct burned into the genes. In any world, food issues are given priority, and it becomes more and more obvious in this world.
If you don't use superpowers, then there are so many details that need to be considered for farming and reclamation.
Why was the Qin Dynasty able to unify the Central Plains? It was because of the two major water conservancy facilities: Dujiangyan and Zhengguo Canal. One was in Shu and the other in Shaanxi. They built their base camp into a granary. In this way, the whole country could have troops and no worries. Qin was the only country.
A country that builds multiple water conservancy facilities.
Ishigami Senku didn't think about the water conservancy problem. He just wanted to solve the food problem quickly and then build ships to go to sea. Of course, he would not forget to search for oil resources, but after 3,700 years, the terrain has changed long ago. Even if he knew
He couldn't find the general direction of the oil either.
It would be a waste of time to send people to search on the ground, but it would be much faster if they could search in the sky.
So the balloon was invented.
This requires Ogawa Gang's super tailoring ability. She is a member of the school's handicraft department. As long as she is given needle and thread, she can create the world.
The principle of a balloon is very simple, that is, hot air rises, and there is no need for an airtight balloon. Air leakage does not matter. What is important is that it is big enough and strong enough, and it must not fall apart while flying.
Of course, balloons are not absolutely safe, but Senku Ishigami doesn't care at all. He is willing to take risks, because if he can find oil, he can solve many problems.
"If oil can be discovered, manpower will no longer be needed to reclaim wasteland, but machines can be used." Since cattle have not been tamed, we can only skip the bioenergy stage.
In fact, it’s not just the cattle that have not been tamed. The map they opened is only a small part. There are also dogs hunting in groups and bears lurking, not to mention lions and tigers. In the map that is not yet clear.
Full of all kinds of dangers.
However, human beings do not follow martial ethics and have paper armor and bows and arrows. As long as humans want to occupy the land, the beasts on this land will be unlucky.
The hot air balloon is made of animal skins. Because it is spring, the animals are very active and have hunted a lot of prey. A large amount of leather is put together, and the Ogawa bar is turned into a huge bag.
Dulan stood on the tree and watched the stone god Qiankong doing things here and there again. He shook his head in disappointment: "At this time, we should build new water conservancy projects first."
We need to do a good job in water conservancy first. Summer will be the rainy season. If water accumulates in the farmland, everything will be over.
"Oil won't run away with long legs, so why are you so anxious?" Dulan didn't understand why Shishen Qiankong was so anxious. He obviously didn't lay a good foundation.
In the original work, he was so anxious because he was anxious to find the catalyst for nitric acid production and create more nitric acid as soon as possible. Then he sailed to the New World to find corn, hoping to produce more alcohol as soon as possible. In short, he wanted to create as many resurrections as possible.
Liquid, resurrect more people.
But now, through the teachings of Ogawa Gang, didn't we agree not to resurrect everyone and develop civilization based on primitive people?
Then he doesn't need to make more nitric acid, nor does he need to find raw materials to make alcohol. What is he worried about?
Dulan couldn't help but look at a small statue that Wu Ding and Fuhao had found, and thought about sending a spy to ask. In fact, Dulan could see through the brain of Stone God Qiankong, but that would be too cheating.
This small statue is the sister of The Lion King. She still maintains the posture of lying on the hospital bed, but she can be cured as long as the petrification is removed. Because the energy of petrification is so magical, it can cure all diseases, even old scars.
Remove with one click.
It was so miraculous that Duran was amazed. It was the first time that Duran had seen such a special healing light.
The petrification light can petrify people, but it does not cause death. The petrified people are still alive. Then the appearance will be weathered by wind and rain, and the weathered area cannot be restored. If the stone statue is broken, as long as it is before the weathering occurs
Use adhesive to stick it back, and it will still be intact when the petrification is removed.
While removing petrification, it also takes away everyone's injuries and scars. I don't know if it can cure hair loss and athlete's foot, but I guess it can, because petrification simply makes people look brand new.
It can be said that the advantages outweigh the disadvantages.
Now Duran is going to help the Lion King's sister to remove the petrification. He only needs a little mixture of nitric acid and alcohol. There is no need to pour it all over the stone statue. He just needs to pour it from the head. Then it will be like a chicken breaking out of the egg.
Normally, the petrified shell will be peeled off, and a completely new person will be reborn.
The girl stood blankly in front of Duran. She felt that her breathing was so smooth. It had been a long time since she had felt the feeling of breathing without a ventilator. It was so relaxing.
Dulan smiled and tried his best to show his friendly side: "Little girl, my name is Dulan, and I am your brother's friend."
"Brother?" The girl remembered, but her brother was not around: "Where is this place?"
"This is 3,700 years in the future, and you have had a long sleep." Dulan explained slowly, letting the girl know the current serious situation.
It has to be said that the resurrected people are very strong and can quickly accept the reality without doubting that everything is a joke or just a nightmare. The girl was also confused at first, but her eyes soon became firm.
"Your brother is in a bad situation now. He was deceived and made the same mistake again. He entrusted his fate to an untrustworthy guy." Dulan really looked like a conspirator at this time: "So I hope you can help him.
