The process of convincing the tribes along the Tao River was not easy, and those tribes who lived alone on the edge of the cluster were almost unable to feed themselves, and in the face of fragrant wheat cakes and novel stories, they often let their guard down and agreed to the northward migration of the fleet.

And those settlements that are far away from the banks of the Tao River and have begun to huddle together for warmth, they have formed a consortium similar to the tribal alliance in Yangya City, and in the face of this southward crossing dragon, the resistance of the local snakes has begun.

Going north may have a good life, but most of the chiefs are like Matsuko, and taking them over the authority to lead the alliance is tantamount to a declaration of war.

Standing at the head of the Alliance, those who came up from the water were invaders, objects to be driven out, while for the common people of the tribe, birch and camelina brought food and hope for a better future, and the attitudes of the upper and lower classes were quietly separated.

However, the reason why the leader is the leader is because he has in his hands the violent institutions that rule the alliance, and an armed battle of more than 100 people broke out along the Tao River.

Birch and Camelina's belts were all out-of-production soldiers who would not get seasick, plus thirty men drawn from the city of Sheep's Teeth, seventy people in front of the hundred-man team marched in orderly steps, and the rest of the stragglers scattered to cover the flanks and rear of the phalanx.

Blood and severed limbs were flying, the grass was dyed bright red, and the tribal leader's team of dozens of hunters was the opponent of this army that had been training every day for a year, even if it was thirty people drawn from the Sheeptooth Tribe, it was not something that their force could handle.

Birch and camelina carry out the will of Gu Guo, recruit obedient tribes when they encounter them, and fight those who are disobedient, history is written by the victors, and the process of plundering population unification will be accompanied by blood and fire.

San's tribe is a good template, but it's a top-down purge, and almost all of them aspire to live like the Gu people.

But the tribesmen of the lower reaches of the Tao River did not see with their own eyes endless wheat fields, wild boars and goats that could be slaughtered at any time, and the oppression and exploitation of the leaders were taken for granted.

Although the clansmen in the tribal alliance have a yearning for Liang Cheng of Gu State, due to the deep-rooted blood kinship and clan in the tribe, most of them are still on the side of the leader and blood kinship.

The leaders of the tribal alliance who stood on the side of the fleet were proper "traitors" in the eyes of the tribesmen, and although this colonialism-like approach would be criticized by future generations, there were now two ways to rapidly expand the population and land.

The simplest thing is to divide the important people in the city, give them knighthoods, and let them stand on their own, as long as they recognize the Liangcheng of his Gu country as the orthodoxy of civilization.

Even if Liang City declined after he left, it was not impossible for the princes to want to replace the Liang Tianzi set up by him, and there would always be princes and kings like Qin who turned the tide like Qin and unified the world.

This method is based on the fact that he is the only one time-traveler in the world, but the system seems to have more than one time-traveler.

In this way, if the feudal vassal states encounter a modern or future traveler, they can see at a glance the disadvantages of the feudal system, and once the disaster year comes, the peasants in the fields cannot pay the taxes, and there may be a hostile traverser behind the scenes, and the armed peasant rebel army can disintegrate the vassal state.

The other way is to gather all the people around him, and it will not be easy for the other travelers to rebel against him in the core area.

Gu Guo felt that he was different from the atrocities of the footbasin chicken's invasion of China, the footbasin chicken's mouth was full of high-sounding East Asian co-prosperity, but in fact, as the former little brother saw the decline of the eldest brother, the extreme inferiority complex made the footbasin face his own suzerainty more and more sick, and the idea of wanting to replace it was very loud, so the slogan of "common prosperity" became a proper invasion.

But Gu Guo really brought a good life to the tribes in the lower reaches of the Tao River.

Bronze tools have raised the city's buildings to the next level, and the first dozens of low-rise houses that could only be made of rammed earth have now been used as cattle pens and pig sheds, and a small number of people have moved into two-story wooden buildings.

The first floor of these buildings is made of wooden pillars, rammed earth and mortar, and after the ceiling is suspended with wooden beams, the second floor is a pure wooden structure.

And these are the most advanced and fashionable houses in this era, and they are naturally inhabited by those who have the ability, such as Xiaofeng, who took the lead in building a water wheel, Gui, who built a water canal, and so on.

In addition to the small wooden buildings, the most built inside and outside the city is still the rammed earth hut with kang, which is a copy of the style built by Gu Guo five years ago, and now two kilometers south of Liangcheng, a village with 30 earthen houses is rising from the ground, which is the resettlement house of those tribes south of the Tao River, and the nature of human beings to seek advantage and avoid harm will surely take them out of the cave and sow the seeds of wheat on the fertile plain.

With ox-drawn carts as a means of transportation, there was no longer a need to rely on birch bark boats to transport food and supplies between Liangcheng and the small village.

Gu Guo sat on a flatbed cart pulled by oxen, accompanied by several children who had taken the elective course in medicine, and the dirt road they had passed had been tamped to drive two ox carts side by side.

Gu Guo, who was sitting in front, pointed to the weeds that could be seen everywhere in the field, and patiently explained: "Students, that is a wild purslane, which can cure diarrhea ......"

After five years of study, Gu Guo has completely mastered the simple botanical knowledge exchanged from the system, and he is compiling the contents into a book, before the paper is made, a piece of pottery plates printed with the outlines of various plants are hung at the door of each house, and it is full of some plants for treating minor diseases.

A small group of peasants dug up common plants such as treating diarrhea, hemostasis, and colds written on pottery plates back to the city to plant, and gradually the herbal medicine field formed a scale, and a group of students interested in herbal medicine were born, so Gu Guo added two elective courses in agriculture and medicine.

Some of these students studied chemistry and some studied physics.

One of the children asked, "Teacher Ji, which part of the purslane can be used to treat diarrhea?" Is it the leaves, or the rhizomes? ”

Gu Guo smiled and nodded, then shook his head again.

The head was because the group of children were thinking about the new problem, not just because he was teaching what he knew but didn't know why, and because he didn't know either.

Simple botany is nothing more than counting the most concise kernel of the plant, but the pharmacology is completely blind.

"Do you remember the controlled experiment method taught by the teacher? When you have diarrhea, try it yourself. ”

Looking at the children's shining eyes, Gu Guo could only answer such a not very rigorous answer.
