"What about people? What about people? The leader of the Blood Tiger shouted as he stood in a near-ruined tribal settlement, and more than fifty men surrounded him, looking a little dazed, rummaging through the ruins, as if trying to find something.

This is the third ruin found by the leader of the Blood Tiger, since the Blood Tiger tribe moved from the south bank of the Great River to the north bank of the Great River, the rest of the third month of spring has been busy getting food and tidying up the new home, and in the summer, the leader of the Blood Tiger takes advantage of the fine weather to take the team out to explore, looking for other primitive tribes, preparing to annex the entire tribe or plunder women.

In the stone tablets of the knowledge of the Blood Tiger Tribe, there are many descriptions of the tribes on the north bank of the Great River, and these descriptions are more similar to the Blood Tiger tribes that originally moved to the south bank of the Great River: each tribe has very few people, ranging from a hundred to two or three hundred, and the tribes with more than three hundred people are very few, and most of the tribes live by hunting, gathering wild vegetables and plant roots, using crude stone tools, and the language is very simple......

The people of the tribes on the north bank of the Great River have almost only one advantage left - taller than the people of the tribes on the south bank of the Great River, and often two people from the south bank can deal with a person from the north bank, and they have to pay the price of one death or serious injury, and the Blood Tiger tribe relied on its physical advantage to establish a foothold on the south bank of the Great River.

It's a pity that for hundreds of years, the bloodline of the people of the South Coast has been completely integrated into the Blood Tiger Tribe, and the physical advantage of the Blood Tiger Tribe over the people of the South Bank has been shrinking.

Similarly, now the Blood Tiger Tribe also has a physical disadvantage to the people of the North Shore, and the weapons are still stone spears, stone axes, and throwing spears, but the Blood Tiger Tribe is equipped with vine shields and rattan armor to make up for the physical disadvantage, and even have a little more advantage.

In addition, the Blood Tiger Tribe can fight more adult males, there are more than eighty people, on the north bank of the Great River, a tribe wants to have more than eighty adult clansmen, the total population of this tribe needs to be exceeded, but there are several tribes on the north bank of the Great River whose population can exceed five hundred.

It can be said that the Blood Tiger Tribe has a very big advantage when it comes to the north bank of the Great River, and it will give the Blood Tiger Tribe more than ten years at most, maybe the Blood Tiger Tribe will be even stronger than before the war with the Niu Tribe.

However, what happened next made the Blood Tiger Tribe stunned, and he led people to find three tribal settlements in a row, these three tribal settlements can only be described as ruins now, I don't know how long it has been since there have been no people, some stone basins, stone bowls and other stone tools are thrown on the ground at will, it seems that they have been discarded.

What about people? Where have all the people gone? Was it wiped out by another tribe or moved?

The leader of the Blood Tiger didn't know that in the past month or so, he had only harvested three ruins, and he would continue to take people to search for the rest of the summer, and only stop in the autumn to get more food.

In the Dragon Tribe, which was three days away from the north of the Blood Tiger Tribe's residence, their life was still going on in an orderly manner, and the Dragon Tribe had no idea that a stronger tribe had migrated from the south bank of the Great River to the north bank of the Great River.

The dragon tribe has not explored the big river for a long time, and the area between the south of the dragon tribe and the big river has almost been explored inside and out by the exploration team led by Yuan, and the primitive tribes over there have been conquered or destroyed by the dragon tribe, so naturally there is no need to explore there.

The construction area of Bamboo City, the third city of the Dragon Tribe, and the road between Bamboo City and Source City have been opened, and when the weather is fine in summer, Yuan will lead the team to level the road or repair the construction area of Bamboo City.

Zhucheng, like Yuancheng and Chicheng, is adjacent to the river that is nearly twenty zhang wide, and the straight-line distance between Zhucheng and the Blood Tiger Tribe almost takes a little more than two days.

In such a large area, the team led by the leader of the Blood Tiger has not yet explored here, perhaps as the exploration range of the Blood Tiger Tribe increases, the Dragon Tribe will eventually collide with the Blood Tiger Tribe and the Blood Tiger Tribe will also regard the north bank of the Great River as the place where the Blood Tiger Tribe rises, but they don't know that on the north bank of the Great River, there is already a super tribe that is several times stronger than the Niu Tribe that defeated the Blood Tiger Tribe was born.

Summer is coming to an end, and it's time for the harvest and babies to be born en masse, and in the first half of this year, the carpenters of the Dragon Tribe have made two great contributions to the Dragon Tribe: larger wooden boats and longbows taller than men.

Since the discovery of the river, Su Yan has restarted the wooden boat construction program, and has experience in the construction of the first wooden boat and the second wooden boat, the third wooden boat, the fourth wooden boat and the seventh wooden boat launched in the second month of this summer.

Seven wooden boats are comparatively larger, and one wooden boat is larger than one wooden boat.

The first experimental wooden boat was a bit small, more than a foot long and four feet wide, and could only accommodate four people.

The length of the second wooden boat was increased to two feet, and the width was increased to six feet, which was enough to accommodate more than a dozen people.

By the seventh wooden ship, the length had reached six zhang, and the width was as much as one and a half zhang, which could carry more than ten tons of cargo at a time, and could carry about 100 adults at a time.

What's more, the seventh wooden boat has been added with sails, although it is only a sail that cannot be turned, but it can rely on the wind to move quickly without paddling in downwind weather.

If you want to continue to build a larger wooden boat, the difficulty will increase exponentially, and the specifications of the seventh wooden boat are enough for the Dragon Tribe for the time being, not only can you drive on the river adjacent to the Dragon Tribe, but also can run smoothly on the big river with a more turbulent current, and when the construction of Bamboo City is carried out next year, you can use the wooden boat to transport supplies back and forth or something.

The only thing that is still a little defective here is that the sail will be able to turn in the future, and even if it is not downwind, as long as the sail is at a certain angle to the wind direction, the sail can still be pushed forward by the wind force.

Su Yan doesn't have much experience in shipbuilding, so he can only provide some ideas, and the carpenters will have to explore the rest by themselves, but fortunately, the people of the Dragon Tribe have learned to think for themselves, instead of only working every day, they don't need to worry about food, and they have time to think about other things.

In the primitive era, canoes and rafts or rafts were the first boats to appear, with the simple tools of primitive people, it was probably easier to make wooden rafts than to make canoes, and I don't know which of the two boats appeared first.

About 3,000 years ago, wooden plank ships began to appear in China, and after the appearance of wooden plank boats, it showed its strong vitality and laid the foundation for the further development and transformation of ships.

Subsequently, in the practice of long-term sailing, people created a ship that used the power of the wind to move - sailboats, and the progress from the sails that could not be turned in the early days to the sails that could be turned later was very fast.

In the Qin Dynasty, it was possible to build a sailing ship that was ten zhang long, two to three zhang wide, and could carry 60 tons across the sea. In the Han Dynasty, it was possible to make hundred-foot building ships; By the Song Dynasty, it was able to manufacture large ships with a load of more than 200 tons; In the Ming Dynasty, Zheng He went to the West to take the treasure ship, which was nearly 50 zhang long and 20 zhang wide.

At present, the shipbuilding level of the Dragon Tribe is equivalent to the level of the Zhou Dynasty, which looks poor, but it is already the highest level of shipbuilding technology in the primitive era.

In addition to the achievements of the wooden boat, there are also achievements on the bow, the dragon tribe's recurve bamboo bow has developed to an upper limit, limited by the limited conditions in the primitive era, coupled with the upper limit of the bamboo bow itself, in terms of bamboo materials, the recurve bow has not much room for development.

Several other carpenters were working on making a recurve bow from better materials, but only Yue Qi, the former patriarch of the Moon Clan, was working on the longbow.

Still limited by the times, the recurve bow is much more troublesome to make than the straight longbow, it is difficult to make much progress in a short period of time, for primitive people, in the open battlefield, the arrows shot by the straight draw longbow can have greater power and have a larger range.

The upper range of the dragon tribe's recurved bamboo bow is 30 zhang, and there is not much power at the distance of 30 zhang, and it is almost difficult to shoot through the animal skin, if it is placed at a distance of 20 zhang, a rattan shield or a single rattan armor can be shot through by the arrows shot by the recurve bamboo bow, giving the enemy who is protected by the rattan shield or rattan armor a huge damage.

On the south bank of the Great River, the Dragon Tribe's recurve bamboo bow is already the most advanced bow, and the straight bow used by the Niu tribe to defeat the Blood Tiger Tribe can't shoot through the rattan shield or rattan armor at a distance of fifteen zhang, maybe other tribes have better bows, but none of them can be compared with the Dragon Tribe's recurve bamboo bow.

With the advantage of the recurve bamboo bow, even if the dragon tribe is now fighting on the south bank of the Great River, it has a very big advantage, but Su Yan thought of a question, the recurve bamboo bow now has an advantage.

But if you want to guard against the recurve bamboo bow, it is also simple, one is to increase the thickness of the rattan shield and rattan armor, and the other is to use a thick wooden shield, this change can only be penetrated by the longbow with greater power and longer range, which is also the reason why Su Yan supports Yueqi's research.

Of course, in addition to the recurve bow and the straight draw bow, there are crossbows, but crossbows are more troublesome to make, Su Yan does not understand the production of crossbows, so he can only rely on the carpenter himself to explore, but it is better to make a longbow.

The straight-drawn longbow is too simple to make, and when studying the recurve bow, Yueqi is doing some research on the longbow, and even makes some longbow experiments out of bamboo.

Bamboo was one of the worst materials that could be used to make bows, and it was not long before Moon Qi abandoned it in search of other materials in the jungle.

The back of the arch is bent from a whole piece of wood, and the best material is purple shirtwood, which is hard and elastic, but it is not found on the north bank of the river, it may not be available, or it may be very rare and cannot be found.

In addition to purple wood, hard materials such as elm, ash, and oak are also available alternatives, but the performance is always worse.

The most common on the north bank of the Great River is elm, which is also the material chosen by Yueqi as a longbow.
