The environment did have a great influence on the development of primitive tribes, and it is easy to see this by comparing the tribes living on the north bank of the Great River with the blood tiger tribes.

There are three aspects: food, clothing and housing:

Clothes, this piece is not too different.

The people on the north bank of the river used leaves or plant leaves as clothing in the hot summer, and spent the rest of the time wrapped in a piece of animal skin. The Blood Tiger Tribe only wraps itself in large pieces of animal skin during the cold winter, and the rest of the time only wraps itself in small pieces of animal skin that have been cut to cover important parts of its body.

residence, there is a certain gap between the two.

On the north bank of the river, the tribes lived partly in caves, while others built rudimentary houses, which could easily freeze to death in the cold winter.

Only a small number of tribes were able to build slightly better houses, with tree trunks and branches as the framework of the houses, the roofs were mainly laid with plant leaves, and the houses were surrounded by walls made of stone and earth, which were similar to the houses that the Blood Tiger tribe now inhabited, and the possibility of freezing to death in winter was greatly reduced.

Food, the gap opens up here.

The tribes on the north bank of the river use hunting as the main way to obtain food, supplemented by fruits, wild vegetables, plant roots, and more than half of the tribes near the river will fish from the river, but the fishing method is very simple, basically holding a wooden stick sharpened at one end into the river to spear fish, fishing is inefficient.

Moreover, the vast majority of tribes on the north bank of the river live a life of hunger and fullness, and almost every year some tribesmen starve to death.

In the Blood Tiger Tribe, the ways of harvesting food such as picking fruits, picking wild vegetables and plant roots still exist in the Blood Tiger Tribe, but the Blood Tiger Tribe mainly obtains food in three ways, namely hunting, fishing and farming, and the status of hunting is still under fishing and farming.

Fishing is the most important fishing method of the Blood Tiger Tribe, which can provide a lot of meat for the Blood Tiger Tribe, and more importantly, the Blood Tiger Tribe has used fishing nets woven with grass ropes to catch fish, and the fishing efficiency has been greatly improved.

Cultivation ranks second, there is only one kind of crop planted by the Blood Tiger Tribe - round yellow beans, the beans produced by the Blood Tiger Tribe every year are enough to occupy a quarter of the annual food consumption of the Blood Tiger Tribe, but the yield per mu of beans is not high, and the farmland area cultivated by the Blood Tiger Tribe every year has reached the upper limit.

The variety of ways to harvest food has allowed the Blood Tiger tribe to barely reach the point where all its people can eat enough, and only in a few years will people starve to death.

In terms of food, clothing, and housing, it can be seen that there is a huge gap between the Blood Tiger tribe and the tribe on the north bank of the Great River.

In fact, when the Blood Tiger tribe first came to the south bank of the Great River, the way of life of the tribes on the north bank of the Great River is similar to that of the tribes today, the fishing nets used for fishing, the cultivation of crops and even the simple pottery firing technology were all obtained by the Blood Tiger tribe from other tribes through conquest, more precisely, there is a huge gap between the tribes on the north bank of the Great River and the tribes on the south bank of the Great River.

The warmer environment than the north bank of the Great River makes the tribes on the south bank of the Great River develop faster than the tribes on the north bank of the Great River, and this is still the tribe in the area near the south bank of the Great River, if it is further south, how far will the tribes develop there?

Anyway, it is impossible for the Blood Tiger Tribe to know, the Blood Tiger Tribe was scared away before it advanced further south, and could only stop in the area on the south bank of the Great River, slowly growing from a tribe of only more than 300 people to more than 1,300 people.

For many years, the Blood Tiger Tribe has been developing, but now it has been completely hit hard by the Ox Tribe, the Blood Tiger Tribe with a total population of more than 1,300 people, now there are less than 900 people left, and the direct loss of more than 400 people is still the most important adult for the tribe.

The Blood Tiger Tribe has reached the most dangerous time, and it is a good thing to be forced to return to the north bank of the Great River, at least there is no powerful tribe on the north bank of the Great River that can threaten the Blood Tiger Tribe, if it continues to stay on the south bank of the Great River, the Blood Tiger Tribe that has been hit hard may be completely wiped out by the former opponent of the Blood Tiger Tribe.

It's just a pity that the large farmland cultivated around the Blood Tiger Tribe, when it reaches the north bank of the Great River, all the adult laborers of the Blood Tiger Tribe must be busy getting food every day, otherwise many people will starve to death.

The lack of adult labor made the leader of the Blood Tiger decide to use the twenty-seven teenagers who were close to adulthood directly as adults, which alleviated the problem of adult labor shortage.

The head of the cow brings people over to watch the movements of the Blood Tiger tribe almost every day, the blood tiger tribe does not move to the north bank of the river, the head of the cow will not return with the clansmen, if the blood tiger tribe does not move, the head of the cow will use war to force the blood tiger tribe.

The Blood Tiger Tribe no longer has a choice, and the old Wu finds the knowledge of making wooden rafts from the stone slab where the Blood Tiger Tribe records the inheritance of knowledge.

The Blood Tiger Tribe fishes by the river every morning, and the afternoon and even some of the evening are used to make wooden rafts.

The wooden raft is very simple to make, just use a straw rope to tie up multiple pieces of wood, and the Blood Tiger Tribe has made a large wooden raft that can carry more than a dozen people, and the number of children is doubled.

Three days later, the Blood Tiger Tribe made fifteen wooden rafts, and the fifteen wooden rafts made five to six trips, not only could all the remaining clansmen of the Blood Tiger Tribe be transported to the north bank of the Great River, but also the items that the Blood Tiger Tribe needed to bring with them to move.

The wooden raft has been made, the Blood Tiger Tribe is not in a hurry, the adult clan needs time to practice rowing the wooden row, and the Blood Tiger Tribe also needs time to prepare a lot of food, moving to a new place, food is the most important issue.

In the middle of the third month of spring, the Blood Tiger tribe was already ready, and during this time, they also sent people to build a simple camp on the north bank of the river, but fortunately, the wooden raft did not overturn a single time when it traveled on the river, and only one male tribesman accidentally fell into the river and was finally swallowed by the river.

Choosing a good weather, the Blood Tiger Tribe was ready to move, and on this day, the Niu Leader also brought his clansmen over.

"Send the kids over first, and then these things." The biggest headache for the leader of the Blood Tiger is the stone tablets that record the inheritance of knowledge, the knowledge of hundreds of years ago is still well preserved, but they are too heavy.

On the surface of the river, which is more than 200 zhang wide, fifteen wooden rafts sail from the south bank of the river to the north bank of the river, and on each wooden raft there are two adult clansmen who hold flat logs as oars to row wooden rafts, and the speed is very difficult.

Wu was very worried, worried that the wooden raft would overturn, and the knowledge inheritance of the Blood Tiger Tribe simply recorded that the Blood Tiger Tribe came from the north bank of the Great River to the south bank of the Great River, when two wooden rafts capsized, and the turbulent river swallowed dozens of clansmen.

Wu feared that something happened, in the third trip, a wooden raft capsized, two adults and twenty children fell into the water, and the other rafts tried to lean over to rescue the tribesmen who fell into the water, but in the end only one adult and seven children were rescued, and the others were swallowed by the river.

The Blood Tiger Leader's hatred for the Ox Tribe deepened even more.

"I swear that I will absolutely destroy the cattle tribe and kill them! Kill them! ”
