Many things can't be delayed, and there are not enough people at the moment, so Yu Zai called Yu Liang and gave him a painted plank.

The specific operation process was carved out with a copper cone, and Yu Liang's eyes were a little straight, and he scratched his head, feeling that he could understand every step, but it seemed that something was not quite right.

Yu Zai smiled, and said seriously: "The land can be cultivated, the ashes of the burning mountain have been mixed with the soil, and the water attracted by the snake has irrigated, this land has not been used for tens of thousands of years, and the land is already very sufficient." ”

"So, we're going to use something to make sure we can land faster this year. ”

Yu Zai said: "This is just the simplest appearance, this thing can be more complicated, but we don't have a cow now, and there is no way to use more complex instruments...."

Yu Liang was a little confused.

Cattle?

During this period, cattle did not have the function of arable land in most areas, and cattle were only raised by large tribes, most of them were for sacrifices, or to take skins, eat meat, and of course there was also a use for pulling that kind of log cart and part-time business as a taxi driver in ancient times.

Because the plow, that is, the thing that Yu Zai is now preparing to let Yu Liang make, has not yet fully appeared, and only a very small number of advanced areas have the "prototype" of this thing.

Speaking of which, the plow is not a high-level machine.

But it is true that like the tribe that invented the jade wheel before, advanced technology does not mean that his combat effectiveness is high, so it is common to fight the streets or something in the mountains and seas, and the first to try to use a plough instead of a shovel board was the Hemudu people 7,000 years ago, and then the Egyptians from afar 5,000 years ago.

In short, the plough was fully popularized in the era, about the period of the Xia Solstice Shang, and the plough at this time was already an ox-drawn plow, not a human plow in the early Xia Dynasty.

At this time, most people use the tools to turn the ground, or "plow", yes, it is the thing in the hand of Dayu sculpture, Hemudu 7,000 years of title endorsement, ancient gold shovel, quality is guaranteed, and absolutely easy to use.

It is a pity that there are no cattle, mules and other major livestock, otherwise, the semi-automatic "machine" of the columbladder can also be made, this thing was invented in the Western Han Dynasty, in short, it is the first in the history of the world to be able to carry out two-tube to seven-tube operations of the "semi-automatic seeder".

Of course, the ox must be pulled in front, and the person must be supported in the back, but that's it, and then the ox pulls, the person supports, and there is no need to push, there is a funnel in front, and there are grain seeds in it, and there are rakes and ploughshares below, which can complete the work needs of ditching and planting at the same time.

Yu Zai saw that Yu Liang was still a little unclear, so he clapped his hands: "Okay, I'll work with you to make one first, this thing is not a high-end product, but it may be used to exchange seeds." ”

Although he has been preparing to start the white wolf from the Tiller Sprout Clan's empty gloves, after all, he has not really made contact yet, and now he is just a general speculation, and it is of course good to be able to add a little less chips, but he also has to prepare for both.

Since they are good at planting, they will certainly not be able to refuse such a good thing as "plowing".

And on his own side, maybe he can get a cow.... Of course, the premise is that the other party has domesticated cattle.

"Bang" the stone axe split the wood, Yu Liang found a few friends to help him lay his hands, and then in a crackling, it didn't take much time for a primitive plow to be made.

This is the first human plough, the structure is simple, the ploughshare is stone, it is easy to damage, but for agricultural production at this time, it is enough to be called an artifact.

Yu Liang set up this thing, held it in his hands, and took a few steps on the ground experimentally.

There are two kinds of manpower plough in single mode and double mode, Fei Zai is now doing the double mode, the front is a little like a rickshaw, there are two handles stretched out to lift up, and there is a place in the middle where the rattan is tied, and the following words are the structure of the normal straight plow.

Yu Liang's eyes became brighter and brighter, and he said happily to Yu Zai: "This can be simplified." ”

Yu Zai said: "There is no need to simplify, two people save some effort, and one person is very tired." ”

Yu Liang shook his head: "Isn't there a shortage of manpower in the tribe now, if you can do something by one person, don't let two people do it." ”

Yu Zai sighed with some emotion and patted him on the shoulder: "Although the strength is great, it is not used like this, protecting your body is the most important thing, compared to overdrawing the labor force, it is better to retain some strength to deal with unexpected disasters." ”

Yu Liang was a little confused, Yu Zai knew that he didn't understand the reason why he didn't understand the word "labor", maybe because he didn't quite understand the dependence between social production and human activities, but he needed to understand, and not for too long, after all, this is not a profound word.

"However, you can also use the simplified single-player version to tiller the sprouts....."

Yu Zai grabbed his hair, in order to deal with the contact problems that arose next, he had discussed at least five or six plans with others, but this kind of social activity could not be guaranteed to be foolproof, after all, this was to do business, not to exterminate the clan.

But just as something good had just been invented, a young man came over in a hurry outside.

"Wu! something's wrong, a messenger from outside has come over, claiming to be suing the master!"

Yu Pan's expression was a little nervous, and when Yu Zai heard this, he immediately stood up: "Sue Shi?"

Since crossing the river and entering the jurisdiction of Xunshan and Chaisang, the priest in charge of the presiding priest has been in a fugue state, and has not had any contact with them at all, and this suddenly came...... After all, it's still ..... Coming to ask for food?

Yu Zai pondered for a while, it seems that the estimation is wrong, maybe the Xunshan clan doesn't care about himself and the others, but the sue Shi clan ..... Moreover, in this matter, the Sushi clan can find the place of residence of himself and others within ten days, which must be inseparable from the Yuhong clan.

Yu Liang and they obviously understood, and whispered to Yu Zai: "Wu, it must be the Yu Hong clan, after they handed over the grain, they told the master that we haven't paid the grain yet, among them.... I'm afraid I don't know how many bad things I say about us. ”

Yu Zai looked serious, thought about it for a while, opened his mouth to Yu Liang, and pointed to the plow: "Hide this, and tell the clansmen, let the more tired, like the clansmen who kept vigil last night, get outside, don't rest to work, let the good clansmen hide and don't show their heads." ”

"Let Yu Yu transport the prepared 100 stone grain to the back of the leather shed. ”

Yu Liang doesn't like to talk very much, since Wu has spoken, just do it, but although Yu Pan is young, he likes to talk a lot, and he is a little entangled at this time, and said to Yu Zai: "Wu... Really give it?"

Yu Zai looked at him and nodded seriously.

"We can ignore the request of the Yu Hong clan, but sue the Shi clan, we can't help but be afraid now, I'll go and see what he wants to ask, if it exceeds the scope of normal sacrifices.......

An imperceptible fierce light flashed in Yu Zai's eyes, but it quickly hidden.

flashing a fierce light does not mean that you have to directly use an axe to cut people, sometimes ..... To understand the situation, it is not only a situation in which people are stronger than people, but also a situation in which the sky is stronger than people.

"The south of Yanze is not a good place, sometimes, strange beasts are infested, thunder and fire are split, and it is normal for people to die. ”

Yu Zai patted his face: "I'm really like a little villain, the kind that can't survive three chapters." ”

"Tell the messenger, I hope you are a good person. ”
