Through the introduction of the high priest, Wu Han and Shan Lin learned some about the snake tribe, and the outline of a snake tribe appeared in the minds of the two, but the internal situation of the snake tribe was still vague.

The heart of defense is indispensable, the high priest is not stupid enough to tell Wu Hanshanlin about the situation of his tribe, no matter whether what they say is true or not, this Xia country can make such a big wooden boat and come to the snake tribe from a long distance, which shows that the strength of this Xia country is very strong, and it is very likely to surpass the snake tribe.

Since they can come to the snake tribe by boat, they can also send a large army to come by boat, once the Xia country has bad intentions towards the snake tribe, then the snake tribe will be in danger, and they have to be careful to guard against it.

The snake tribe is indeed a very powerful tribe, and inexplicably, the development method of the snake tribe has some similarities with the Xia Kingdom.

When the population reached a limit during the Dragon Tribe's time, the Dragon Tribe began to build a second city, moving half of the population to the second city, and as the population increased, the Dragon Tribe continued to build new cities, and the size of the cities was almost the same.

The same is true of the snake tribe, when the population reaches a certain limit, the second settlement is built, followed by the third, the fourth, and the fifth, the first residence is the largest, with a population of more than 5,000, and the other four settlements have a population of about 4,000 people, and the total population of the snake tribe exceeds 20,000.

What's more, the cities of the Xia Kingdom are adjacent to the river, and the residence of the snake tribe is also adjacent to the river, and fishing has a very high status in the Xia country and the snake tribe.

Farming is affected by climate change, and climate change does not have as much impact on fishing as farming, and in the previous years of severe natural disasters, crop yields were severely reduced, and the snake tribes relied on large-scale fishing to feed their stomachs.

The snake tribe may not have existed as long as the fishing tribe, but the development of the snake tribe is definitely a little faster than that of the fishing tribe, both tribes are able to smelt copper, weave linen, make wooden boats, etc., from the details point of view, the snake tribe's technology in these aspects is a little more advanced than the technology of the fishing tribe.

Skip the rest for now, one of the most powerful aspects of the snake tribe is witchcraft, in the legend of the snake tribe, witchcraft is given to the snake tribe by the gods, and the snake tribe can cure sick people through witchcraft.

Witchcraft is medicine, using herbs to cure diseases, not only the snake tribe, other tribes have more or less such witchcraft, even the original snake tribe, tiger tribe, when the tribe is injured, the witch will let the tribesmen look for a plant, the juice of the plant is applied to the wound, which can speed up the recovery of the wound to a certain extent.

Speeding up the recovery of wounds is just the simplest witchcraft, as wise men, the witches of various tribes will continue to try all kinds of witchcraft, and make more witchcraft, some witchcraft succeeds, and more of them fail, fortunately, they carry out witchcraft to seriously ill people, witchcraft fails, and the result is like that, if it succeeds, it is simply a surprise.

According to the law of time and population, it is often the tribe that has been inherited for a longer period of time and has a larger population, the higher the level of development of witchcraft.

The snake tribe has a long heritage, with a population of more than 20,000, and under normal development, the level of witchcraft will not be weak, at least minor diseases such as diarrhea and fever can be cured.

The Serpent tribe attaches great importance to witchcraft, and the high priests and priests also require their successors to spend a lot of energy on witchcraft, and their research attempts are effective.

According to the previous division, Su Yan's medical skills are at the advanced level, the Wu and Wu disciples of the Xia Kingdom are at the intermediate level, the clansmen who have graduated from the advanced academy have just entered the primary level, and the students who have not graduated are apprentices, so now the witchcraft of the high priest of the snake tribe can probably reach the level of the middle of the primary level.

Don't underestimate the level of medicine in the middle of the primary level, like the fishing tribe, which is groping on the edge of the apprenticeship to the beginner, and most of the other tribes are also at the level of apprentices, like those small tribes that live by hunting, they can only use plant juice to speed up the recovery of wounds.

Of course, no matter how much the snake tribe's witch develops, it can't catch up with the Xia Kingdom with Su Yan in charge.

Wu Han and Shan Lin were guests in the snake tribe, the two sides had relatively friendly contacts, and finally the two sides made some trades, the snake tribe has other things in the Xia country, there is nothing to trade, only the crops of the snake tribe are the most interesting to the third trade team, the snake tribe is a super tribe with a population of more than 20,000, planting a variety of crops.

Most of these crops are owned by the Xia country, and a small half is not owned by the Xia country, and some of them have to be traded back, before the third trade team traded upland rice from a tribe, but I didn't expect to find rice in the first residence of the snake tribe, and the new varieties of crops naturally had to be traded.

The crops planted in the five settlements of the snake tribe are basically the same, millet, soybeans, hemp, etc., but there are also a small number of other varieties of crops, and the first residence is the most, and even some common medicinal herbs are planted.

Probably seeing that the goods brought by the Third Trade Fleet were very good, the High Priest decided to take out some animal skins and exchange all kinds of goods for a small amount, without thinking too much, the snake tribe or the original fishing tribe had the same mind and wanted to study something from these goods.

The third trade fleet left, and continued to sail eastward, this trip can sail as far as the forty-fifth day, and then return, the snake tribe brought a lot of novelty to the people of the third trade fleet, and also traded some new kinds of crops, but just like that, the matriarchal clan is not a novelty, there is also a clan in the Xia country that once lived on a big tree.

Don't forget the purpose of sending trade fleets out of the Xia Kingdom, contact the various tribes, it is best to be able to carry out some trades, and it is better to be able to trade the population, so that the various tribes can feel the strength and wealth of the Xia Kingdom, but the ultimate goal is to let the tribes join the Xia Kingdom, so that the Xia Kingdom has a faster development speed.

The purpose of contacting the snake tribe has been achieved, anyway, the Xia country is far away from the snake tribe, take your time in the future, maybe one day the snake tribe will not be satisfied with its own living situation, and the entire tribe will join the Xia country.

The third trade fleet came into contact with one tribe after another, and finally turned into circles of different sizes and marked them on the map, and by the way, they would also use pen and paper to record some of the tribes they came into contact with, such as population size, strength, technology level, etc.

Until the forty-fifth day of the voyage of the Third Trade Fleet, the Third Trade Fleet turned around and prepared to return, and it was about ninety days to come and go, and it was already summer when it set off in early spring, and it was already summer when it returned, and the Third Trade Fleet could only go twice a year at such a long distance.
