Chapter 2398 Adventure and Farming

Ishigami Senku wants to open up wasteland because there are more people now and wheat is obviously not enough. Because primitive people have small appetites, while old humans have big appetites, strong men can eat a lot, and it is best to have meat every meal.

However, it is obviously not that simple to open up wasteland. First of all, there is water source. Farmers need water, but there are no water conservancy facilities. All water is taken from the lake. The fields near the lake are fine, but the farther away from the lake, the greater the cost of opening up wasteland. Because there is no irrigation water conservancy, the cost of opening up wasteland will be extremely high because water needs to be carried by manpower.

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

The second is the damage to farmland by birds and insects. Sparrows were listed as the four pests in the past because sparrows compete with humans for food and because sparrows damage farmland.

The more land there is, the weaker the monitoring is, and the more it is impossible to avoid the damage of crops by birds. Anyone who has farmed, or even grown vegetables, knows that when the season of harvest arrives, birds fly around in groups, and the scene is black and dense, among which sparrows are the most conspicuous.

So it is not as simple to open up wasteland as Ishigami Senku thought. Of course, he has invented iron tools, so using a shovel to dig canals for drinking water and using iron tools to open up the land can 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 dig water conservancy. Before the emergence of water conservancy facilities, the harvest of the fields was completely dependent on God's will, and people could not control whether there was more water or less water.

Duran found that after coming to this era, the farming gene in his body seemed to have awakened, and he was very knowledgeable. Sure enough, farming is an instinct recorded in the genes. In any world, food issues are given priority, and this world is even more obvious.

If you don't use superpowers, then farming and reclamation require consideration of so many details.

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, so that the whole country could be mobilized without worries. Qin was the only country that built multiple water conservancy facilities.

Ishigami Senku did not 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 a long time ago. Even if he knew the approximate direction of the oil, he could not find it.

If someone was sent to find it on the ground, it would be a waste of time. If it could be searched in the sky, it would be much faster.

So the balloon had to be invented.

This requires Xiaochuan Gang's super high tailoring ability. She is a member of the school's handicraft department. As long as she is given needles and thread, she can create the world.

The principle of the balloon is very simple, that is, hot air rises, and there is no need for airtight balloons. Leakage does not matter. The important thing 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 Ishigami Senku does not care at all. He is willing to take risks, because if he can find oil, he can solve many problems.

"If oil is discovered, we won't need manpower to reclaim wasteland, we can use machines." Because the cows are not tamed, they can only skip the bioenergy stage.

In fact, it's not just the cows that are not tamed. The map they opened is only a small part. There are also groups of hunting dogs and lurking bears, not to mention lions and tigers. There are all kinds of dangers in the unclear map.

However, humans don't have martial ethics. They 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 now, the animals are very active and hunt a lot of prey. A large amount of leather is put together, and the small river bar becomes a huge pocket.

Duran stood on the tree and watched Ishigami Senku doing this and that and making a great leap forward again. He shook his head disappointedly: "At this time, we should build new water conservancy first."

First, build water conservancy. In summer, it will be the rainy season. If the farmland is flooded by then, everything will be over.

"Oil won't run away, why are you in such a hurry?" Duran didn't understand why Ishigami Senku was so anxious, even though he didn't have a good foundation.

In the original book, he was so anxious to find a catalyst for nitric acid production and make more nitric acid as soon as possible. Then he sailed to the New World to find corn, hoping to make more alcohol as soon as possible. In simple terms, he made as many resurrection liquids as possible and resurrected more people.

But now, after Xiaochuan Gang's teachings, didn't they agree not to resurrect everyone and develop civilization based on primitive people?

Then he didn't need to make more nitric acid or find raw materials for making alcohol. What was he in such a hurry for?

Duran couldn't help but look at a small statue found by Wu Ding and Fu Hao, thinking of sending a spy to ask. In fact, Duran could see through Ishigami Senku's brain, but that would be too cheating.

This small statue is the sister of Shishi Wang Si. She still keeps lying on the bed, but her disease can be cured as long as the petrification is removed. Because petrification energy is so magical, it can cure all diseases, and even old scars can be removed with one click.

It was so magical that Duran was amazed. You know, it was the first time for Duran to see such a special healing light.

The petrifying ray can petrify people, but it is not death. The petrified people are still alive, and then the wind, rain and sun will weather the surface, 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 petrification is removed.

The petrification also takes away everyone's injuries and scars. I don't know if it can cure hair loss and athlete's foot, but it is probably possible, because petrification is simply a brand new look.

It can be said that there are more advantages than disadvantages.

Now Duran is going to help the lion king Si's sister to remove the petrification. All he needs is a little mixture of nitric acid and alcohol. There is no need to pour it all over the stone statue. Just pour it on the head. Then, just like a chick breaking out of an egg, the petrified shell is peeled off, and a brand 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 felt the feeling of breathing without a ventilator. It was so relaxing.

Duran smiled and tried his best to show his friendly side: "Little girl, my name is Duran, and I'm your brother's friend."

"Brother?" The girl remembered, but her brother was not around: "Where is this place?"

"This is 3,700 years later, and you have had a long sleep." Duran explained slowly, letting the girl know the current serious situation.

It must be said that those who have been resurrected are very powerful, and they can quickly accept reality without doubting that all this is a joke or just a nightmare. The girl was also confused at first, but soon her eyes became firm.

"Your brother is in a bad state now. He has been bewitched and repeated the same mistakes, entrusting his fate to untrustworthy guys." Duran really looked like a conspirator at this time: "So I hope you can help him."
