Crossover in the Anime World

Shi Shen Qianku wants to open up wasteland, because now that the population is large, there is obviously not enough wheat. Because primitive people have small appetites, while old humans have large appetites, macho men can eat very much, and it is best to have meat every meal.

However, land reclamation is obviously not that simple. The first thing is the water source. Farmers and farmers 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 cost of land reclamation. big. Because there is no irrigation water conservancy, the cost of land reclamation will be extremely high because manpower is required to carry water.

Another problem is water accumulation during the rainy season. Farmland is not only afraid of less water, but also afraid of too much water. When there is too much water during the rainy season, if there is no drainage, the crops will die.

The second is the destruction of farmland by birds and insects. 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, 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 will fly around in flocks, making the scene completely dark, and among them, sparrows are the most conspicuous.

Therefore, land reclamation 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 an 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 was completely determined by God's will. More or less water was beyond human control.

Dulan discovered that after coming to this era, the farming gene in his body seemed to have awakened, which was called a clear-cut approach. Sure enough, farming is an instinct burned into genes. In any world, food issues are given priority, and in this world it becomes more and more obvious.

If you don't use superpowers, then there are so many details to consider for farming and reclamation.

Why was the Qin Dynasty able to unify the Central Plains? It is because of the two major water conservancy facilities: Dujiangyan and Zhengguo Canal, one in Shu and the other in Shaanxi, that 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 to build multiple water conservancy facilities. nation.

Ishigami Qiankong 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 look for oil resources, but after 3,700 years, the terrain had changed long ago, and even if he knew the general direction of the oil, he could not find it.

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, the balloon is not absolutely safe, but Ishigami Senku 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. Machines can be used." Since we have not tamed cattle, we can only skip the bioenergy stage.

In fact, it’s not just the cows 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, humans 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 skin, because it is spring, the animals are very active, and they have hunted a lot of prey. A large amount of leather is put together, and the Ogawa bar is turned into a huge bag.

Du Lan stood on the tree and watched Shi Shen 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 to find a catalyst for nitric acid production and produce more nitric acid as quickly as possible. Then they sailed to the New World to find corn, hoping to produce more alcohol as soon as possible. In short, they wanted to produce as much resurrection liquid as possible and resurrect as many people as possible.

But now, after Ogawa Gang's teachings, didn't he 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?

Du Lan couldn't help but look at a small statue that Wu Ding and Fu Hao had found, and thought about sending a spy to ask. In fact, Duran can completely see through the mind of Stone God Qiankong, but that would be too cheating.

This small statue is the sister of Shishioji. She still maintains the posture of lying on the hospital bed, but she can be cured by removing the petrification. Because petrochemical energy is so magical, it can cure all diseases, and even old scars can be removed with one click.

It was so miraculous that Duran was amazed. It was the first time for Duran to see such a special healing light.

The petrification ray 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 glued back with adhesive before weathering occurs, it will still be intact when the stone statue is removed.

While lifting the petrification, it also took 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 de-petrify. 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 an egg. Suddenly, the petrified shell is peeled off, and a new person will be reborn.

The girl stood in front of Duran blankly. 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 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 it is all 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. "
