How important is a large river about twenty miles wide? There is no doubt that this river can be called the mother river of primitive people.

The environment of the great wilderness is too harsh, the temperature in the dry season is as high as forty or fifty degrees, such a temperature is the same as being in the desert all year round, if there is not enough water, people will not survive at all, and it is easy to die of thirst.

The existence of such a river can ensure that countless people in the Great Wilderness will not die of thirst in the dry season!!

Although Lin Feng is now a great power of the Distraction Realm, he really can't do it if he wants to change the sky, and with this big river, Lin Feng doesn't have to worry so much, he can let the Lishan tribe take root in the lower reaches of the river in the future, saving a lot of trouble.

Lin Feng is quite afraid of trouble.

Casually swept the river with the Yuan Shen, Lin Feng finally nodded with satisfaction, because there are really a lot of fish in this river, it is estimated that no one has come to fish them before, and the fish in the Great Wilderness World are larger than ordinary fish, so the fish resources in this Wei River are really rich.

Relying on the mountains to eat the mountains, relying on the water to eat the water, relying on this Wei River, Lin Feng estimates that it is not a big problem to feed tens of millions of people.

It took Lin Feng half a day to walk along the lower reaches of the Wei River, and finally, Lin Feng felt a big surprise.

There are really a lot of primitive tribes in the lower reaches of the Wei River, the number is more than three or four hundred, although the primitive people are not good at knowledge reserves, but they are not stupid, they know that water is the source of life, many tribes have set up their homes next to the Wei River, and there are several tribes connected in some particularly good places, and these tribes are quite numerous.

In addition, these tribes have changed from simple hunting to fishing and hunting, Lin Feng saw that some tribes already had simple fishing nets, and primitive people had understood the meaning of relying on water to draught.

At the same time, the Wei River is really big and really long, and in half a day, Lin Feng flew thousands of miles, but he still didn't see the end of the Wei River.

Then Lin Feng saw a good place, it was a large alluvial plain, this plain is quite extensive, the area may reach millions of square kilometers, the plain is fertile, there are many tributaries, if it is used for farming, it can definitely build a large granary to supply hundreds of millions of people.

In addition, this plain is not only fertile land, but also countless fierce beasts running on the grassland, in groups, all of which are resources, all of which are gifts from nature.

"If several cities are built on this plain, a few more ports are built on the shore, and some large ships are built, it will not take a few decades for this plain to become the economic center of the entire Great Wilderness..."

It's a pity that due to the lack of time, Lin Feng did not continue to move forward, but Lin Feng guessed that the end of the Wei River should flow into the sea, and it will not be very far from the sea, as long as it is a modern person, it should be able to understand how rich the resources in the sea are, not to mention hundreds of millions of people, even billions of people can be fed, of course, the premise is that it can be developed.

"The Great Wilderness World is promising..."On the way back, Lin Feng thought so.

Although Lin Feng just wants to make the Great Wilderness a granary that supplies his totemic power, as a human being, Lin Feng also hopes that the people of the Great Wilderness can live well, at least they should be safe, and now that the Great Wilderness World has the innate conditions for self-sufficiency, Lin Feng does not need to use means to subsidize.

Back in Manggu, Lin Feng didn't tell anyone about the situation in Weihe, the current Lishan tribe has just merged, and the sense of belonging to Lin Feng is not high enough, Lin Feng is ready to wait for a while.

..............

The new Lishan tribe has entered a period of great development.

The cement road is paved at an unimaginably high speed, with Manggu as the center, and the cement road is paved on all sides, this cement road is hidden in the forest, with the existence of this cement road, the primitive man on the horse can reach any tribal settlement in two hours.

Of course, the scope of the ground split fruit has also expanded, and the forests in many places have been cut down, all of which are used to plant ground split fruit, according to estimates, the harvest of ground crack fruit this year will be at least several million catties, enough for the current Lishan tribe to survive the rainy season and the cold season.

There are food roads, there are roads, clothing, food, housing and transportation in the four categories, the rest is clothing and housing, for these two aspects, primitive people actually don't care so much, clothes can be praised with animal skins casually, and the aspect of living is also very casual, you can sleep when you fall.

Lin Feng didn't have any special requirements for clothing and housing, because to be honest, these two aspects are actually really difficult.

Lin Feng wanted primitive people to build houses, but Lin Feng also had to consider the impact of the rainy season, and he worked hard to repair a house, and when the flood came, the house was all washed away, so what was the point of repairing it?

Because of this, Lin Feng did not let the primitive people build houses, but the cement road was about to be completed, Lin Feng felt that the primitive people could not be idle, and finally thought, yes, just let the primitive people build ships.

Of course, it is to prepare for the following year, next year, Lin Feng is going to let the Lishan tribe through the Wei River all the way to the plain where he looks, and by the way, the tribes around the Wei River will be annexed, and if there is time now, then directly lay the foundation, so as not to be too busy next year.

If you want to build the simplest ship, then you can build it with a single log, but if you want to build a large wooden boat that can carry dozens or hundreds of people, this is quite difficult, especially when Lin Feng does not want to use modern technology to interfere.

It is easy to say that the wood used for shipbuilding is a great wilderness, and there are so many trees that they can be cut down at will, but a ship must not have wood alone, and it needs something else to put the wood together, either with iron nails or glue.

It is very difficult to make iron nails, Lin Feng is going to use glue, that is, gum, he sent people to look around, and finally found a large rubber tree, but if rubber is made into the best rubber raw materials, Lin Feng really doesn't know, so Lin Feng finally had to ask Diao Chan to prepare a rubber production method for him.

After the rubber was manufactured, the technology to make a wooden boat was already available, and the first wooden boat was successfully launched at the end of the dry season when the entire Lishan tribe was rushing to work.

The length of the first wooden boat was twelve meters, the width was five meters, and the maximum number of passengers was twenty people, although this wooden boat was nothing, but there is no doubt that the appearance of the ship opened a new chapter in the Great Wilderness.
