All the way to the other side of the lake, Canglong City. Although Yao Ran has had a lot of experience leaving this time, www.biquge.info he has not been away for a long time.

There are no major changes in coming back to Canglong City this time, everything is going according to plan. A lot of times things are uneventful, and there is a lot of repetitive and tedious work.

What is especially troublesome is that the people working around you are extremely ignorant, and Yao Ran's patience was destroyed again in the next three months.

Obviously it was common sense in Yao Ran's consciousness, Yao Ran didn't realize that these things should be taught to primitive people, but felt that they should be known.

But slowly Yao Ran found that the common sense that he had been learned by the society, by his parents' side, and from his teachers was a simple common sense that had been passed down for thousands of years and exchanged for life or more.

For example, a heated iron pot will be very hot, for example, tomatoes should not be eaten with crabs, they will be poisoned by arsenic, for example, light bulbs should not be stuffed in the mouth. For example, there must be no open flame in the flour mill, otherwise it will ignite the flour in the air and cause an explosion. For example, lime powder cannot be cleaned with water when it enters the eyes, but it can only be washed with oil so as not to burn the blind eyes.

After figuring this out, Yao Ran's complaints decreased a lot, and he tried to convince himself to be patient, but the reality was cruel.

The mechanical principle of artificial spinning machine and loom is very simple, the spinning machine is the spinning wheel, Yao Ran made a kind of hand-shaking spinning wheel, the spinning wheel is composed of wheels, crank handles, spindle rods, brackets, bases, etc.

The base of the spinning wheel made of wood is 70 cm long and has the shape of "gong". There is a small bracket ingot rod at the upper horizontal part of the "work"; There are two square columns at the lower transverse place of "work" is a big support, the column distance is 50 cm, and the upper end of the column has the round hole of the axle of the driving car, 35 cm away from the base. There is a crank at one end of the shaft.

When spinning, one hand holds two strands of cotton to dip the end into water and stick it to the spindle rod, and the other hand shakes the rocking handle, and the driving wheel drives the spindle rod to rotate rapidly, and the height of the hand holding the raw material and the spindle rod usually spin the two strands of cotton together, and move backwards while putting the material.

When the spun thread reaches its length, raise your hand and wrap the thread around the spindle rod. Then, the hand holding the cotton descends back to the level of the spindle rod. You can spin the next thread. This is done repeatedly to complete a thread.

There are many kinds of looms, but if they are not upgraded to above the industrial scale, Yao Ran can only choose some simple, the simplest is the most primitive waist machine, one end is wrapped around the waist of the weaver, and the other end is pedaled with the foot, but in this way, people can not leave, and come back to weave again after leaving, and the thickness and tightness of the cloth will become different.

The loom that Yao Ran is preparing to make is a traditional loom with a wooden bed-like frame, one end of which is a column full of warp threads, and there are six wings at both ends of the head, which can be controlled and rotated.

Not far from the nose is installed an erected frame, whose function is to pull two threads through the horizontal rod above, which is similar to the traditional brown one, which is to separate the separated warp threads and facilitate weft insertion and weaving.

The reel is a rectangular line brush with the same width and height of about 20 cm as the head, the lower part of the reel is connected to two pedals by the lead rope, and the pedal is stepped on in turn, and the reel is divided into two layers, and the warp thread that evenly passes through the thin eye is divided into two layers, and the weaving shuttle passes through the middle of the two layers of warp, leading the weft and the warp to be staggered, and then the cloth is formed through the extrusion of the machine.

This loom is not so difficult, but it is more complicated and troublesome to operate, but there are still advantages, that is, the speed of weaving, and the quality of the finished product are very good.

Yao Ran made ten looms in batches, and the efficiency of a single spinning wheel like thirty spinning wheels was still average.

The manufacture of these textile equipment, the training of female operators, and another teacher training course, these complicated tasks trapped Yao Ran in Canglong City for three months, Yao Ran broke out, and Wei Mu himself stayed in Canglong City, dragging his family and leaving in the direction of Yao Zhai.

Wei Mu smiled in his heart, Yao Ran stayed in Canglong City for a few months, and now the side of Canglong City facing the grassland has been planted with corn, after Yao Ran's selection, the seeds are manually pollinated in a timely manner, and the full corn cob has grown to the length of a palm, and it can be harvested at the end of this month.

Yao Ran predicted to Wei Mu before he left that nearly 10,000 catties of corn could be produced from these two hundred acres of land. Although there are 10,000 catties of corn, they are distributed to the whole tribe, nearly 2,000 people, and no one can get five catties of grain, so the scope of corn planting must be doubled again.

Now the cultivation of land has become an important big project in Canglong City, and Canglong City has now become the largest city of the entire Yao clan, whether it is the urban population, the scale of aquatic products, or planting are undoubtedly an important base of the Yao clan.

Yao Ran handed over the management of this place to Wei Mu, the first point is trust, and the second point is a recognition of Wei Mu, such a city is not good, that is, a big village, a population of three or four hundred, and a few hundred acres of land are not as much as the land of a big landlord's family.

So before Yao Ran left, he asked Wei Mu to expand the current cultivated land by five times. There is no need to cultivate intensively. According to the previous method, there is a forest belt for every ten acres of land, and the road can also be used as a windproof.

The people take food as the sky, after the food is sufficient, they have to find something to do, food and clothing and think about it***Laziness will breed when there is no crisis, after Yao Ran left Canglong City, the first stop to arrive was Cotton City, I don't know if Yao Hemu got the news, or this kid really reformed, there are still about 5 miles away from the city, Yao Ran actually found the sentry.

It was really the sun that came out in the west, Yao Ran walked into the cotton city with a smile, and the wooden wall in front of the walled gate had been piled up with a layer of stone walls.

The front door looks very sturdy and imposing, but only this one wall is piled with stones, and the other walls are not reinforced in this way, and when you enter the city, the streets are not clean, and they are not very dirty.

Seeing Yao Ran's carriage enter the city, many people stopped to watch, wanting to see who was coming. The entire Yao clan counted more than 2,000 slaves, and a quarter of them were subdued on the other side of the lake, and nearly a fifth were newborns.

Why is it said that there are one-fifth newborns, because of Yao Ran's reward policy, coupled with the continuous growth of the team led by Hua Tuo, the survival rate of newborns has doubled. Miscarriages and dystocia in women are becoming less and less common. Naturally, it is not surprising that there are three or four hundred more babies in the entire Yao village in a year.

It turned out that the snow river in Dahe Village, the black pearl-like woman, also gave birth to a big fat boy, but Yao Ran didn't see it.

Most of the people who stopped on both sides of the street knew Yao Ran, and they had all spoken to Yao Ran and listened to Yao Ran's lectures. Seeing that it was Yao Ran, they all stepped forward to salute and say hello reverently, Yao Ran was no stranger to this feeling, but he still enjoyed it. (To be continued.) )
