The wall of the new village was also built at the same time as the granary.

The construction of this circle of walls with a length of 500 meters was intermittent, and this time it was completed in one breath.

The new village has actually changed its purpose and is no longer for living. Because it is planned to build an outer city wall in the future, it is no longer appropriate to call the new village a new village, so Ye Qing changed the name to the inner city.

Now there are more people in the tribe. The original four doors are not very convenient for people to communicate with each other. Ye Qing opened two slightly smaller doors on each wall, so there are twelve doors in the entire inner city.

The twelve gates are evenly spaced, which makes it much easier for people living outside the inner city to enter and exit.

The door opening is also very wide, with four ox carts entering and exiting at the same time with four main doors. Six ox carts entering and exiting at the same time with four main doors.

In this era, land is not valuable. As long as you have the ability, then try your best to enclose the land.

The road is built more wide, with only the benefits but no harm.

While the tribe members were busy building barns and inner city, Ye Qing started another task.

During the recruit training, the tribe planted soybeans were harvested.

Before the soybean harvest, the patriarch led his breeding team to collect enough seeds to be planted in the coming year.

The patriarch's breeding team has also expanded.

He absorbed the older witch, who was already unable to do physical work among the relocated tribes, into his own breeding team, which expanded his breeding team to twenty people.

As for the young and strong witches, there are naturally other people waiting for them.

Wild soybeans are first grown manually, and the yield is not very high.

According to the final statistics, the yield per mu of land is only about 100 kilograms.

You know, this acre is a large acre of 1,200 square meters, and the output is very low.

The main reason for low yield is that after the soybeans mature, many pods explode automatically.

The soybeans sprinkled on the ground were basically gone by the time of harvest by insects, ants and mice. Even the remaining ones were moldy, rotten, and useless.

Ye Qing had no choice but to do this.

If you want to obtain soybean varieties whose pods will not explode automatically, you can only continue to plant them year by year and cultivate them slowly.

Ye Qing didn't know how many years it would take, maybe ten years, maybe a hundred years, or a thousand years.

In this era, there are advanced scientific and technological means. If you want to cultivate excellent varieties suitable for planting, you can only rely on stupid methods, that is... planting year by year, selecting seeds year by year.

At this time, Ye Qingbian thanked his ancestors extremely.

Thanks to the rice seeds left by ancestor Minming that will not automatically leave even if they are mature.

It was hard for him to imagine how he would ensure that the people of his tribe would have enough food if the rice planted would still be automatically threshed like wild rice.

No one can tell how many years of cultivation the ancestors have had, but the process must be very long.

Archaeologically, the earliest site where rice planting was the Shangshan culture in the upper reaches of Qiantang River, which was more than 11,000 years ago.

Even the tribe is more than six thousand years away.

This is an extremely long time!

The ancestors are great!

...

The soybeans were harvested, and Ye Qing began to process the by-products of soybeans.

There are soybeans with more by-products, and Ye Qing only chooses a few to process them.

The first one is soybean oil.

The lack of edible oil has always been a very distressing thing for Ye Qing. Although there are animal oils that can be used by chance, there is still too little animal oil.

With a stable source of soybeans, from now on, the tribe's edible oils will have a stable source of food.

The processing method of soybean oil is not difficult.

It's just a word for squeezing.

The tribe members have seen oil pressing, but at the end of last year, a lot of tung oil was squeezed.

But soybeans can also squeeze oil, which surprised the tribe.

Ye Qing put the dried soybeans into a hydraulic mill and crushed them. He removed the shell through a blower, and then crushed them into powder through a hydraulic mill again.

Stir in the soybean powder in a pot until it is slightly yellow, and then press on the press.

The press has also been improved, and it is no longer the leverage press that was last year.

Ye Qing rebuilt a spiral press.

The key component of the screw press is the manufacturing of nuts and screws.

Without strong lathes, screws and nuts can only be cast.

Therefore, the screws and nuts are quite rough, and it is impossible to have modern precision.

For this reason, the screws and nuts made by Ye Qing are very large in size and are equivalent to the thickness of an adult's arm.

Inadequate accuracy, cannot match?

Stupid method, polish.

After casting, it is polished by hand.

A press only requires a set of screws and nuts. The polishing work does not actually take much time.

Wrap the fried bean flour in cloth, put it in the press, then turn the handle, rotate the screw, and a round bronze plate slowly press down.

When pressed to a certain extent, oil began to seep out of the small holes on the wall of the thick, round container surrounded by bronze plates with dense holes.

Seeing the increasing amount of golden transparent soybean oil, the people watching the tribe began to get excited.

They are not excited because they have edible soybean oil.

They were excited because of the golden color of soybean oil.

The yellow color of soybean oil is very bright. This color is extremely beautiful for the tribe, and it is an ultimate temptation.

This is the color of the artifact, the color of silk, and the same color of soybean oil, it looks very unusual.

They all praised:

"So beautiful!"

"Look, it's like silk, bright and slippery!"

"The same color as the artifact, is this...the magic oil?"

Ye Qing: “…”

God tm God Oil!

Soybean oil is for eating...

The pressed soybean oil is very heavy in color and can only be considered rough refining and will not enter the circulation link in later generations.

There is also a refining process for pressing soybean oil in later generations.

However, for the tribe, such soybean oil is enough, and refining is not necessary and cannot be done.

In this era when many tribes cannot get enough food, this is already a luxury.

In the final result, Ye Qing calculated that for 100 kilograms of soybeans, the final oil squeezed was only ten kilograms, and the oil yield rate was only ten%.

One hundred kilograms of soybeans only produce ten kilograms of soybean oil...

This is very luxurious!

Soybeans are also food!

Of course, the bean cakes after pressing can also be eaten.

However, tribal rice and dried fish are sufficient, so these undespicable bean cakes will not be used as food.

The ultimate use of these bean cakes is to... feed pigs, chickens, and cows.

Seeing the best food and finally used feed for breeding livestock, the tribe members felt very distressed.

In addition to heartache, they suddenly realized that the tribe was completely different from before. Faced with more and more food, they now have room for choice and can choose...

This was completely unimaginable before!
Chapter completed!
