The obsidian of the Dugu clan, Yang Li did not value it very much, in fact, he reached a trade agreement with Dugu Cheng to go to the north bank of the Yellow River to reconnoiter the terrain and distribution of forces, and prepare for the future enemy and annexation.

The so-called soldiers and horses have not moved, and the grain and grass go first, and the first thing is the reconnaissance operation.

Before the Mongol Empire sent troops to the Russian countries, it sent Subutai and Jebe to reconnoitre, preparing for the future large-scale westward expedition, bloodbathing Eastern Europe, entering Central Europe, the conqueror's feat was not a fluke, and under the brave and fierce skin of the Mongol iron cavalry, there was a plan that two generations of genius commanders had to spare.

Yang Li is glad that he did not travel to the Southern Song Dynasty or the Qing Dynasty, otherwise the difficulty of recovering China would have become hard, and in ancient times, everyone only had the concept of tribes, and the sense of civilization was weak, and there was no iron law of pork piercing the intestines in later generations, and there was no scruple about who Maria's father was, so the population integration after the conquest was quite pleasant.

The distance between the Dugu clan and the black blood clan is close, Yang Jiao wants to go over to find out, although the general terrain is familiar to him, but the vegetation, water system, what specific soil, and what can be used as cultivated land, everything must be personally investigated.

There are many ways of reconnaissance, from word of mouth, to rangers, to unmanned reconnaissance aircraft in later generations, human warfare continues to integrate with the development of science and technology, and reconnaissance methods have become diverse.

However, Yang Li had to stabilize the economy of the sharp increase in slaves after the tribal war, and also had to deal with the distribution of interests among slave owners, and also instructed the new group of people who joined the ruling class to manage slaves and grow crops, and even had rudimentary legal texts that he needed to formulate, and the most primitive medieval courts needed him to establish, and he certainly could not go out to reconnoiter in person.

The cost of sending scouts is high, but the benefits may not be sufficient, because according to the number of coalition troops gathered by the black blood clan, there are at least 10,000 settlements in the north, that is, across the Yellow River and towards the west.

The population was too large and the land was too large, and the small-scale scouts simply couldn't have enough information, so Yang Li took another approach, which was to send caravans.

The so-called caravanserais, nominally for trading obsidian, are actually for spying on the military and gathering intelligence.

Yang Li has to judge which tribes can be co-opted at that time, which ones need to be eliminated, which ones can be used in alliances, and which ones need to be divided.

This is task one, task two is to find a new place for azurite mines, if it is close, it will be hit, and if it is far away, it will be traded.

Trade with different cities, judging whether a trade deal can be reached, is secondary.

Through trade with other tribes, Yang Yu was able to bring to them a small number of advanced production techniques and social concepts in the riverbend, such as the obsolete lacquerware-making technology, as well as the finished pottery products, plus the wooden plough used by manpower, to live in these settlements and communicate with their people, so that their living habits and production methods can be understood.

Of course, it is not excluded that the hostile tribes are closed, but with the Dugu clan as a collaborator, which clans can go and which cannot, they can naturally learn through them.

At noon half a month later, Dugucheng ate half a deer leg and took his five clansmen on the road generously.

The fat man had teary eyes and waved goodbye to his cousin: "Rong Rong, you must wait for me to come back, you have to believe that I will be able to rescue you!" ”

"Goodbye." Jiang Rong smiled kindly.

Dugu Cheng was followed by a caravan of thirty-seven people, of which twenty-five were pulling carts to pick up goods, five were maintaining goods, and five were wearing obsidian blades at their waists, holding round shields, carrying wooden bows and arrows, and escorting them.

The two caravan leaders joined the team, one of the leaders was Zhang Zifang, an old merchant from the original ash wood settlement, and the deputy leader was Lie Shan Huang, Lie Shan Qi's second son.

Yang Li specially handed over the few obsidian blades to the guards of this caravan, and told them to put safety first, to explore the terrain and vegetation first, and to communicate with the tribes later, and to arrive at the Dugu clan is a great achievement.

He had considered letting Xue Bijiang serve as a caravan guard, but the incident happened suddenly, and the young man couldn't go.

What happened, two days ago, Yulia took Zhen Mi out to play, and the little tiger alarmed a small herd of bison and drove towards the river.

In the past, if it was a dozen bison rushing at the same time, it would have taken a lot of effort to hunt, but now there are good hunters in the riverbend, and there is a standing semi-professional army, so everyone rushes up and catches the bison.

In the entire river bend, the only person who can tame an adult bison is Xue Bijiang, this guy has amazing balance ability, jumping on the bison, the butt is stuck to the back of the cow, allowing the cow to jump on the top corners, and he can't even touch a single hair of the teenager.

After struggling, it is often Xue Bijiang who walks leisurely, occasionally going to the side to drink water and eat meat, but the bison is stunned and paralyzed on the ground, unable to move, and has a stubborn temper to come again.

There is a big black cow that is so different, with a wide frontal bone, dragon horns, more than one person tall, and a visual weight of nearly two tons.

What is Longmen Kok?

Ordinary bison, some of the horns bend to both sides, and some rush up, but this Longmen horn is straight forward, impartial, as long as the cow lowers its head, the Longmen horn is two gun-like killing weapons!

Huya practiced with this guy, but people were not convinced, because when it rushed over, it was dodged by Huya, and then it was defeated in a head-on wrestling, so this cow felt that his strongest attack move was not cracked, and he was not convinced.

But when it came to Xue Bijiang, it was different, the bison raised the horn of the dragon gate and rushed forward, the young man saw the opportunity, put his hand on the horn, and the whole person was like a big ape, and he borrowed the strength of the cow's neck in a moment.

This is a move that positively resolves the big bison, and people are convinced.

So when Yang Li and Mao Mei were walking by the river last night, they saw Xue Bijiang riding a bison and passing by.

"Hey, young man," Yang Li felt a little incredulous, "don't you use that kind of square-shaped red cloth to tame them?" ”

"No need, big chief," the boy scratched his head, "and what you said about poking it in the back with a little javelin and piercing its spine with a bayonet sword, it's really not at all ......"

This is the bullfighting scene mentioned by Yang Li when he told the story to the boy and Xiao Zhen Mi at that time, and the Spanish bullfighters did just that, and there was a link in the middle, that is, the war horse wearing heavy armor and blindfolded appeared, and the knight on horseback used a horse to attack the bullfight.

"Look, the future human beings are becoming more and more dependent on foreign objects, this is really the world is declining, people's hearts are not ancient, our people can be empty-handed, the so-called agility is not enough, equipment to make up, this is the truth."

If we wait for the cubs of the two bison to grow up and then go to the plow, it will not be possible in three or four years, since we can directly catch the adult cattle and tame them, it will naturally greatly shorten the agricultural development process.

A few days later, the bronze plough came out and put on the big black.

Da Hei is the bison head of Longmen Corner, this guy is currently Xue Pijiang's exclusive mount, only Xiao Xue is alone, and whoever dares to approach others will take the horn arch, and he is a bully in the river bay.

"Do you want me to take something to eat and lead it to the front?" Yulia asked, she found some grass out of nowhere, and tried to discuss it with Yang Li.

"Yes, as long as you have the same running speed." Yang Jiao pointed to the ground.

Mao Mei looked over there, only to see that the little tiger walked over to provoke the bison at some point, successfully pulled the hatred, and was chased by the angry cow and ran all over the ground, and finally one dodged carelessly, so that the cow's nose arched and picked, and suddenly flew into the sky.

"Over there, over there!" Zhen Mi shouted as she ran.

Huya caught up in three steps, caught the little tiger, and returned it to Lori.

Yulia was stunned for a moment, she thought she didn't have the ability to escape like a little tiger, so she dismissed the idea of provoking the bison.

The other bison were brought over and watched together, and the use of cattle as a tool for cultivating land was a great advance in the productivity of human history, before the advent of steam and even firepower, animal power represented and advanced productivity, that is, cattle were not cattle, nor were they ordinary food, but tractors.

These bio-tractors, combined with bronze ploughs, will efficiently reclaim land for more people to cultivate, solve the problem of food for population expansion, and at the same time, bring more food surpluses to accommodate more people to thrive on the land.

Yang Li chose to reclaim a piece of land on the south bank of the Luohe River to the east of Hewan Land, which had not been divided before, because the soil was compact, and there were many scattered stones in it, and it was very laborious to use manpower to reclaim.

It's not that everyone can't work together to remove the stones and forcibly reclaim them, but there is fertile soil on the south bank of the Luohe River, so it can't afford to invest a lot of money, and you can't get along with such a piece of land.

But in full view of all the slave owners and slaves, Yang Jiao wants to prove to everyone that even such a land can be completely easily solved, I can do it now, and you can do it in the future, because the strength of human beings cannot be compared with the large herbivores, they use plants as fuel and muscles as internal combustion engines, and can accomplish things that human bodies cannot do.

Xue Pijiang broke a branch and pumped it on the black cow's buttocks: "Big black, let's go-"

With Xue Pijiang tearing out his voice and shouting, the ploughing ox began to move forward, and the bronze plough cut deep into the land under the action of the angle, separating the soil below, turning up the brown soil rich in organic matter below, weeds and stubborn stones, all separated under the beveled blades of the bronze plow, Yang Li assigned the rear plough to plow, the old farmer was excited, and the corners of his mouth grinned to the back of his head.

Watching the hard-to-remove stones shatter as the bronze plough progressed, the slave owners who came to observe were amazed and began to anticipate what would happen to their land in the future.

"I said, Lao Wang, if you give me a plow and a ploughing ox, then my slave will be able to reclaim twice as much land next year! I can have ten more sons, eight of them will be warriors to fight for the big chief, and the remaining two will join the caravan, and our family will become the largest family in the Riverbend!" ”

"It's beautiful, old Song, who the land is distributed to is calculated by the big leader according to his military exploits, which means that what your family could do with four hard labor prisoners can do now, now two can do."

Lao Wang couldn't help but fall into deep thought: "What about the remaining two?" ”

Old Song's dark circles became more and more obvious: "Of course, it is the farmer who has been liberated into freedom, and the great chief said at that time that when every peasant can use the ploughing ox and farming tools, the future of the river bend land will change again, and they will become farmers who work for us, and we ourselves will not even have to go to war, but become the feudal lords who rule them." ”

Lao Wang squatted down, grabbed a handful of dirt, and rubbed it vigorously, feeling the time 1s1s pass by at his fingertips: "I see, I can't wait to experience what it's like to be a 'lord'." ”

Yang Li didn't know what the two obscene slave owners were discussing, but what he did know was that with the promotion and application of high-efficiency productivity and production tools, more manpower would be liberated, and slavery would no longer be suitable for the river.
