After Da Niu and others got the scientific and technological inheritance of [intensive farming], they already knew the importance of land reclamation, and also understood the basic concepts and benefits of farming.

I have a trace of understanding and expectation of agricultural civilization in my heart.

But farming is a long process that takes a lot of time to get the final harvest.

And it also needs a lot of seeds, careful care, timely irrigation, fertilization, weeding, etc., compared with simple and crude fishing and hunting activities, it is simply tedious and boring, if they have not been brainwashed by the technology tree, I am afraid they are absolutely unwilling to do it.

Simplicity and brutality are the truth in their hearts.

Under the scorching sun, the big bull was constantly beating the wolf rider in front of him with a long wooden stick, and the wolf rider turned its fangs outward, roared viciously and viciously, and kept turning its head to gnaw on the thick hemp rope that bound them, obviously unwilling to obey the control of these new masters.

Behind the rope sleeve is a plough that keeps plowing.

The whole body of the plough is a wooden frame mortise and tenon structure, connecting the front and rear plough wheels are long and bent downward, almost touching the ground, and at the front end of the plough bottom, a large plough shovel shining with a blue-yellow metallic luster, is cast in bronze.

This is another retro masterpiece of Li Hao, invented in the Sui and Tang dynasties, the famous Quyuan plough in ancient China.

Each one is worth 500 tech points, which is five times the size of a bronze spade.

Moreover, after this kind of plough was made, not only did the number of technology points increase extraordinarily, but it also directly unlocked the manufacturing technology of the [Bronze Quyuan Plow], which has been passed down by Li Hao to several clansmen, and is still in production.

Historically, compared with the straight plough that prevailed in many dynasties, this kind of plough wheel was changed to the improvement of bending the ground, and the plow disc that can rotate freely is installed at the head of the wheel, which not only makes the plow frame smaller and lighter, but also convenient to turn around and turn, and the operation is flexible, saving manpower and livestock.

It is more in line with the principle of mechanics and can be easily pulled and ploughed by ploughing oxen.

The application and popularization of the Quyuan plough has greatly improved the labor productivity and cultivated land quality of the ancient ancestors.

It provides an important technical guarantee for the expansion of intensive agriculture in ancient times.

Until later generations, in terms of basic structure, the curved plough was the mainstream plough type of Chinese plough.

It's just that the ploughing ox has been replaced by the ploughing wolf, and the big cow is also the first time they operate, both sides are obviously a little clumsy, and there is no tacit understanding with each other, and even after a few pulls, the man and the wolf will have to fight first, until one side divides the victory and defeat, and then can continue to plow the land.

It's very time-consuming and labor-intensive.

Li Hao looked a little crying and laughing, and was very helpless, it was the first time that the eldest girl got on the sedan chair, and he could understand everyone's feelings, but this new way of working must be persevered.

If a tribe wants to develop steadily, the first thing is that the food source must be stable.

Without a stable and adequate source of food, the tribe will always live in great distress and bondage, and it will be difficult to move an inch.

Although primitive fishing and hunting seem to be able to solve the problem of urgently needed food at the moment, especially after Li Hao developed the fishing rod, the old people in the tribe can get a large amount of fish every day to supply the daily food needs of the tribe.

It looks good, but only Li Hao knows the problem here.

It is impossible to rely on primitive fishing and hunting methods to obtain large quantities of food over a long period of time.

The reason why the problem is not prominent now is simply because the population is not large enough.

Even if there were a few dozen new Beidi captives, their population would be less than four hundred.

Just this person, there is such a large forest in front of him, and he can't starve to death if he collects some wild vegetables and fruits.

But what if you want to grow to a population of 1,000? What about a population of 10,000? Or even a hundred thousand people?

How many wild vegetables, wild fruits, deer and cattle can be supplied to them in the mountains and forests, I am afraid that there will not be enough to eat!

Therefore, the agricultural civilization that has been tested countless times in Chinese history is the future way of tribal development!

Although Da Niu and the others were in a bad mood by Qu Yuan plough and ploughing wolf, when they saw Li Hao always standing under the sun and watching them all the time, somehow, the original irritable mood gradually calmed down again.

"Drive! Don't slack off and keep plowing the land! ”

……

At sunset, the old people and female warriors carried dozens of baskets full of catches, and walked slowly from the Houshan Lake with laughter and laughter.

Seeing that the big cow was still facing the loess with their backs to the sky, carefully digging the soil, and carefully burying something, they were all deeply puzzled.

They had been working in the ground for days, first cutting down trees, then digging up their roots, and now they were playing around here again, and they didn't see anything to eat.

It's really full of food, and it's been in vain here.

Isn't it nice to have this time to fish with them?

……

Ignoring the cynicism of the fishing crowd, Da Niu and others continued to work hard.

"Okay, let's work harder, and we're left with the last ridge of land...... Sowing, sprinkling ......"

As the captain of the farming team, the big cow keeps cheering everyone up, although he is a totem warrior with a thousand catties of great strength, but after a day's work, he has to control the wolf ride from time to time, and they are a little tired.

However, the results were not bad, and the cultivation was almost completed at the last point.

It's just that at this speed, Li Hao was a little dissatisfied and shook his head slightly.

Although it is to catch ducks on the shelves, it is a little difficult for these primitive people.

However, after a day of hard work, dozens of young people have cultivated four acres of land, and this efficiency definitely needs to be improved, and it needs to be greatly improved.

In later generations, several skilled peasant women were three points faster than them, and they didn't need to consume so much food.

Seeing that everyone had basically completed the cultivation, Li Hao thought about the communication system space and summoned a disc similar to the size of an iron pot.

The golden runes on it are difficult to understand, and several metal nozzles as thick as a child's arm are symmetrically erected and shiny and reflective.

This [Small Steam Witchcraft Ripening Machine], which can quickly ripen all crops in ten days, he also took it out and studied it for a long time, but he still hasn't figured out the secret, so he can only use it first.

"Doodoo ......"

After putting a full ten fist-sized spirit yuan stones into it, the witchcraft ripening machine was activated instantly, and the metal pipe kept bubbling up, making a steam sound, and the entire disc body actually flew up slowly.

Then, according to Li Hao's instructions, he flew over the cultivated land and stayed in the air at a height of five zhang.

In the mountain forest, which was already gradually darkening, there seemed to be a faint layer of rune golden light sprinkling from the fuselage, watering the ground below.

"Could it be that those runic golden glows are the secret to the ability to ripen crops?"

Li Hao narrowed his eyes and fell into deep thought.

"It seems that there are still many mysteries in the technology tree that are worth digging into!"

On the other side, Da Niu and the others finally finished sowing the last ridge of the field, drove the ploughing wolf, dragged the zigzag plow, and came back from the field as if they had been freed from some kind of shackles, talking and laughing.

also happened to see the scene of the witchcraft ripening machine flying into the sky, and they all opened their mouths in surprise, "What kind of bird is that?" It doesn't have wings, how does it fly? ”

……

When returning to the tribe, because there was no protection around the cultivated land, Li Hao asked Da Niu to leave ten young men to take turns to be on duty here.

It is not only necessary to prevent wild boars and other beasts from coming to steal the seeds, but also to protect the witchcraft ripening machine from damage.

Although it is far away from other tribes, there is basically no threat from other hostile tribes nearby, except for large and powerful tribes such as the Beidi tribe, generally no one will choose to march and sneak attack at night.

But the stakes are very high, and someone must be here to protect him day and night, so that he can rest assured.
