The problem is that there is only one place in front of the plough where the wooden hook is hung.

If you plough the plough with two deer, you need two rings.

and then drill an eye in the wooden plow to make a ring, such a solution was first proposed by Lame, but it was immediately vetoed by Han Cheng.

Because two deer pulling a plough and a deer pulling a plough are very different, it is not as simple as drilling out one more eye.

There are too many holes drilled on the wooden plow, which will affect the firmness of the wooden plow, and secondly, the force of the two eyes is uneven, and the deer is too difficult to pull up.

It's not just the deer who struggles, but even the people who support the plough in the back.

Wu still had a limp and a strange iron head on the sidelines, and began to stare wide-eyed, but there was nothing to be done.

Han Cheng smiled and asked the limp to cut off a piece of wooden stick half a meter long and about five centimeters in diameter.

In the middle of the stick, there are two more ends that have to be drilled holes.

A wooden hook is tied to the hole in the middle, and wooden rings are tied to the holes on both sides.

As soon as these words came out, after thinking for a while, Wu and the lame face showed a look of joy.

Lame, he ran as fast as he could towards the tribe to make things that Han Cheng had done for him.

The iron head stood there confused, not understanding the reason.

The speed of the lame was extremely fast, and Han Cheng didn't wait too long, he had already brought the things made according to Han Cheng's way, and came over quickly, and the quality and quantity were guaranteed.

Han Cheng took it in his hand and looked at it, and gave a thumbs up to the limp.

Limp and laughing, extremely happy.

Han Cheng hung the wooden hook in the middle of this section of the horizontal wood on the ring of the wooden plow, and at this time, the lame and the iron head also led a well-worn deer over.

Han Cheng picked up the wooden hook that he carried behind the deer cover and put it on the rings at both ends of the horizontal wood, one by one, and the matter was solved immediately.

At this time, Tietou understood how this section of the horizontal wood that Han Cheng had made for the limp was used.

"Hah!"

After putting on the deer and holding the wooden plow, Han Cheng shouted, and the two deer began to walk forward, and the wooden plow easily entered the soil, feeling very brisk.

Two deer pulling a wooden plough together is easier than Uncle Deer's head deer.

Seeing that this result was even better than expected, Wu smiled again......

In early spring, the weather was still very cold, and the kang was still burning in the room.

The night had fallen, and the oil lamp in the room had been blown out, except for some dark red fire light at the mouth of the fire pit, which had not been completely sealed.

Han Cheng lay on the warm kang sideways, quietly reached out to Bai Xuemei's slightly bulging belly, and gently stroked it.

Listening to Bai Xuemei's steady breathing, Han Cheng's heart was calm.

After a while, he rolled over and lay down on the kang and began to think about the ploughing of the wooden plough and the deer.

The advent of the wooden plough and deer ploughing was very useful for sandy land near the river, which he himself experimented with, there is no doubt about it.

However, compared to the joy of Wu and them, the joy in Han Cheng's heart was not so much.

Because he had seen more advanced production methods, he knew that there was still a lot of room for improvement in this kind of wood plough deer farming.

Cows, horses, donkeys, and other big animals and metal mines, these things have to be found in a hurry.

Don't expect to find them all, as long as you can find one, it can also make the productivity of the Qingque tribe get a great boost.

Up to now, if the productivity of the Qingque tribe wants to increase, generally speaking, there are two main ways.

One is to expand the population, and the other is to improve the tools and change the way of working.

After the destruction of the Teng Snake, the population of the Blue Sparrow tribe has grown explosively, and for now, there is no need to increase the population too much.

The rest is to improve the tools and change the way of working.

For the Qingque tribe, which has been moving closer to farming, the most important thing at present is the work on the land.

As long as the efficiency of farming is raised, then the productive forces can be greatly liberated and developed.

In this way, it is back to square one.

Large livestock, sufficient metal, at least one of these two conditions must be met.

But the problem is that none of them can be satisfied......

Iron bacteria can't be counted on, it's too slow to get metal through that thing, and it's still possible to make some key things that are necessary and require a small number of them, and if you want to produce them on a large scale, there is no door at all!

In addition to these two things, there is one thing that is also crucial, and that is the seeds of new crops.

Up to now, there are only three kinds of crops that the Qingque tribe can call - millet, hemp, and rape.

Among them, hemp is used for wearing, and rape cannot be used as a staple food, so that the crops that can really be called staple grains are only millet.

I used to think it was okay, but now it seems that it is a bit single.

You have to go out and about, and it's a long way away.

Whether it is a large livestock or a metal mine, or a new type of crop, there is no near the Qingque tribe, which Han Cheng can be very sure.

If you want to get these things, you have to look elsewhere.

He was essentially a homeless person, but at this time, he also had to go out on an adventure-like journey.

However, this journey cannot begin yet, because at this time, it is necessary to go all out to deal with spring ploughing, and it is impossible to send too many people out.

It will certainly not take too much time to go out in search of large livestock, metal mines, and new crops, and all of them need to be well planned.

However, the tribe now has the original leader of the donkey tribe and a few members, and it will save a lot of effort to go out to explore, at least they are more familiar with the surrounding situation.

Thinking about this, Han Cheng thought of the matter of reforming the trade team with a few people from the original donkey tribe as the skeleton, and it was time to start implementing this matter and so on.

After all, this is the only means by which the Blue Sparrow Tribe maintains its influence over those surrounding tribes, and it cannot be easily abolished.

"Bang Bang Bang ......"

In the dark room, I suddenly remembered a crackling sound, the sound was not small, and it was particularly clear in the quiet room.

Don't think crookedly, it's not that Han Cheng, who can't sleep, is doing something embarrassing, but he is sitting up on a bone kang and slapping his head hard.

How did I forget this stubble!

Han Cheng thought excitedly and secretly annoyed, his mood fluctuated greatly.

If you think about this earlier, maybe the tribe has already started smelting metal utensils by this time! Where else do you need to be melancholy here!

"Cheng... Brother Cheng, what's wrong? ”

The movement made by Han Cheng woke Bai Xuemei from her sleep, and she opened her eyes and opened her mouth in a daze.

"It's okay, it's okay, it's just that I suddenly remembered something."

Han Cheng suppressed the excitement in his heart, quickly lay down, and covered the mattress so as not to run away.
