The problem is that there is only a small space in front of the wooden plow for hanging the wooden hook.

If two deer are used to pull the plow, two rings are needed.

The idea of ​​drilling a hole in the wooden plow and making a ring was first proposed by Bo, but it was immediately rejected by Han Cheng.

Because there is a big difference between two deer pulling a plow and one deer pulling a plow. It is not as simple as drilling an extra hole.

Having too many holes on the wooden plow will not only affect its firmness, but also cause the force on the two holes to be uneven, making it too difficult for the deer to pull it.

Not only the deer had a hard time, but the person holding the plow behind it also had a hard time.

Wu, Lame, and Tietou, who was watching curiously, started to stare at each other, but there was nothing they could do.

Han Cheng smiled and asked Bo to go back and cut a wooden stick that was half a meter long and about five centimeters in diameter.

Drill holes in the middle and at both ends of the wooden stick.

Attach a wooden hook to the middle hole and attach wooden rings to the holes on both sides.

As soon as these words were spoken, after thinking for a while, Wu and Lame both showed expressions of joy and enlightenment on their faces.

He limped and ran quickly towards the tribe to make the things that Han Cheng had asked him to make.

Tietou stood there in confusion, unable to figure out the reason behind this.

Bo's speed was extremely fast. Han Cheng didn't have to wait too long. Bo had already come quickly with the things made according to Han Cheng's instructions, and they also ensured the quality and quantity.

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

Lame was laughing, looking extremely happy.

Han Cheng hung the wooden hook in the middle of the crossbeam on the ring of the wooden plow. At this time, Bo and Tietou also came over with a leashed deer respectively.

Han Cheng picked up the wooden hook on the back of the deer harness and hooked it onto the rings at both ends of the crossbar, one on each side. The problem was immediately solved.

At this time, Tietou finally understood how to use the crossbeam that Han Cheng asked Bo to make.

"ha!"

After harnessing the deer, Han Cheng, who was holding the wooden plow, shouted, and the two deer began to move forward. The wooden plow easily entered the soil, feeling very light.

It is easier for two deer to pull the wooden plow together than for Uncle Deer alone.

Seeing this better-than-expected result, Wu smiled again...

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

Night had fallen and the oil lamp in the room had been blown out. Only from the mouth of the fire pit, which was not completely sealed, some dark red light could be seen.

Han Cheng lay on his side on the warm kang, quietly reaching out his hand and gently stroking Bai Xuemei's slightly bulging belly.

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

After a while, he turned over and lay flat on the kang, and began to think about the wooden plow and deer plowing.

The emergence of wooden plows and deer plows is very useful for sandy land near rivers. He has personally tested this and there is no doubt about it.

However, compared to the joy of Wu and the others, Han Cheng was not as happy as they thought.

Because he had seen more advanced production methods, he knew that this kind of wooden plow and deer plowing still had a lot of room for improvement.

We need to hurry and find large animals like cattle, horses, and donkeys, as well as metal mines.

We don't expect to find them all, but as long as we can find one, the productivity of the Qingque tribe will be greatly improved.

At present, if the Qingque tribe wants to increase its productivity, generally speaking, there are two main ways.

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

After destroying Teng Snake, the population of the Qingque tribe has experienced an explosive growth. For now, there is no need to increase the population too much.

What remains is to improve tools and change working methods.

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

As long as the efficiency of farming is improved, the productivity can be greatly liberated and developed.

In this way, we are back to the starting point.

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

But the problem is that none of them can satisfy...

You can't count on iron bacteria. It's too slow to obtain metal through them. They're OK for making some necessary and key things that require small quantities, but large-scale production is simply impossible!

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

Up to now, there are only three kinds of crops that can be called agricultural crops in the Qingque tribe - millet, hemp and rapeseed.

Among them, hemp is used for clothing and rapeseed cannot be used as a staple food. So, the only crop that can truly be called a staple food is millet.

I thought it was okay before, but now it seems a bit monotonous.

I have to go out for a walk, and go somewhere far away.

Whether it is large livestock, metal mines, or new types of crops, none of them are found near the Qingque tribe. Han Cheng can be sure of this.

If you want to get these things, you can only look for them somewhere else.

He is essentially a homebody, but at this moment, he has to go out on an adventure-like journey.

However, this journey cannot start now, because we need to devote all our efforts to spring plowing and it is impossible to withdraw too many people.

Going out to look for large livestock, metal mines, and new crops will certainly take a long time, so it requires careful planning.

However, the tribe now has the original donkey tribe leader and several members, so going out to explore will save a lot of effort. At least they are more familiar with the surrounding situation.

Thinking about all this, Han Cheng remembered that he would reorganize the trading team with a few people from the original donkey tribe as the skeleton. It was time to start implementing this matter.

After all, this is the only means for the Qingque tribe to maintain its influence on the surrounding tribes, and it cannot be easily abolished.

“Pah pah pah…”

In the dark room, there was a sudden burst of popping sounds. The sound was quite loud and was particularly clear in the quiet room.

Don't get the wrong idea. Han Cheng, who couldn't sleep, was not doing something embarrassing. Instead, he sat up on the kang and slapped his forehead hard.

How could I have forgotten this!

Han Cheng was thinking with both excitement and annoyance, his mood fluctuating greatly.

If you had thought of this earlier, maybe the tribe would have already started smelting metal tools! Why would you still be sad here?

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

The noise made by Han Cheng woke Bai Xuemei from her sleep. She opened her eyes and spoke in a daze.

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

Han Cheng suppressed his excitement, lay down quickly, and covered himself with the mattress to prevent the wind from escaping.
