Gu Yi roared unbearably and drove away the mine clerks like the children waiting in line for the Ferris wheel, leaving only Suiqian with one of his subordinates in charge of the mill. They didn't need their efforts. They just poured the unpeeled millet in and swept out the pounded one. The two of them were enough to take care of ten stone mortars and donkey heads.

But after a while, the Pincai ran to Gu Yi with a panic look on his face. The hydraulic mill was pounding rice too fast. Ten stone mortars were used at the same time. Soon, a large pile of millet was pounded out. Gu Yi had to order a temporary suspension of work. This is a typical manifestation of productivity exceeding demand.

Moreover, the pounded millet is mixed with millet bran, so it cannot be used directly. It has to be used in the process of wind removing bran. However, how to separate millet bran from the piled mountains has become another problem.

If you use the principle of rice weight and light bran to remove the mixed millet bran in millet with the wind, although the efficiency is a little slow, there is a way at least. But in this deep well-like sinking valley, there is not even a trace of wind, then that's not a big deal? You can't blow it slowly with your mouth, right?

In desperation, Gu Yi had to invent a wooden "hand-cranked bran-removing drum". This thing was very common in the countryside in the early days. There were several windows on the wooden drum of an octagonal spinning wheel. By shaking the wooden handle, the millet and millet bran poured into the inside roll. As long as the shaking speed is controlled, the centrifugal force can be used to easily separate the rice and bran.

The birth of the "hand-cranked bran removal drum" naturally surprised the mine clerks. The eyes of Gu Yi were full of respect, and they also worked hard to do the work assigned by him. They obviously regarded him as a master at the level of "Lu Ban".

Gu Yi didn't care about these small objects that he "invented" casually. As long as it could meet the requirements, he never thought that the things he made casually would have an impact on the world...

Winemaking experiments and wine cultivation were carried out simultaneously. After all, he is only sweet wine now. It is not enough to make good wine. The quality of wine is slowly accumulated. After hundreds of generations of elimination and selection, the best wine can be selected as a "greed" to pass on to ensure that the quality of each brewing is consistent.

This process is called "professional terms" inherited by Gu Yi from his hometown's small wine shop, and the reason is nothing more than cultivating the fungi in the wine. Gu Yi is not like in the original world, he can buy the prepared wine for a few cents. Everything has to be cultivated from scratch.

Therefore, this leads to Gu Yi being an experiment rather than making wine. All the large and small pottery jars bought from [Shuiwatun] came in handy, steaming the processed millet, adding glutinous rice, mixing water, putting it into the jar, and sealing the cellar.

Fortunately, he now has many helpers, and he can do the work by opening his mouth and directing him. Otherwise, he would not be able to do such a large-scale experiment alone.

When he opened his mouth and ran off his legs, everyone, including Ge Qiao, was commanded by him, was wandering around and was not idle for a moment. He himself carried a stack of booklets bound by leather paper, and used a "pencil" made of a woman's eyebrows to draw, and kept writing and drawing on the booklets. In the eyes of everyone, this behavior became more magical and mysterious, and became more and more unaware.

After finishing the winemaking work, before everyone could breathe a sigh of relief, Gu Yi found work for everyone. On this trip, they bought a lot of braised soil, packed in straw bags and piled them under the shed. If they were eaten, it would be enough to pickle more than 100 people into mummies.

But Gu Yi bought these braised soils not for eating. After some "market survey", Gu Yi found that the world was extremely "salt shortage". Even those high-ranking officials and nobles lived by eating natural salt crystals. This was undoubtedly another way to make money for Gu Yi.

The brine soil is diluted with water, the salt content is filtered out, impurities are adsorbed with specially-fired charcoal, and then multiple filters are performed using a filter made of coarse to fine quartz sand and layers of brocade cloth.

Finally, I set up a large cauldron, added black stone to stew and cooked crystals, and obtained pure snow-white salt grains by boiling salt, which is what the world's great officials and nobles called "ice-brown snow crystals". In fact, in Gu Yi's opinion, this thing is at most coarse salt, and even refined salt cannot be considered.

However, for this world where even the "high-quality braised crystals" eaten by dignitaries are astringent and bitter, and maybe mixed with gravel that can break off big teeth, this "ice braised snow crystal" as white as snow and fine as sand is something they have never heard of or seen!

Seeing that Gu Yi was able to "refine" the "ice and snow crystal" from the black brine mud, not only those mine clerks, but even the white people regarded it as miracles and almost knelt down to kowtow to Gu Yi, the "Tianshi Shangxian", which scared Gu Yi. After asking, he realized that salt was not just the seasoning he imagined, but an extremely rare survival necessity.

People do not have the strength to eat salt, and will be weak and prone to illness. However, more than 90% of ordinary people in this world eat "light food", that is, the "original flavor" without oil or salt. If you don't have any oil or salt, you will be roasted with fire and boiled with water. It's considered delicious food.

Why do people in this world clearly have a rich nature, but only eat a few things?

The main reason is that they lack effective cooking methods and seasoning assistance. Most of the natural ingredients have an original flavor. They are fishy and bitter when eaten in their mouths, and are not considered to be something that can be eaten.

For ordinary people, salt is a nourishing medicine for strengthening their bodies and expelling evil and diseases. For the soldiers who rely on their strength to make a living, salt is a treasure that enhances their strength!

Previously, Gu Yi took out a little salt foam filtered out from the bruxite that he had cheated from Ge Qiao, and convinced Baimin, Roupu, Mao people and headed him because salt, whether in the Baimin's war team, Roupu and Mao people's tribes, they are rare materials controlled by the commanders, leaders and chiefs. Only when they make meritorious service will they receive a little reward.

As soon as Gu Yi met, he took out the "ice-brown snow crystal" they had never seen before and gave them food. It was equivalent to the behavior of Qianjinshi horse bones, and they had enough to make them work for him. Otherwise, with Rou Pu's barbarity and the brains that were not much smarter than gorillas, how could he be so obedient and obedient under Gu Yi?
