The reason why the Bai Min, the Rou Servants, and the Mao people are so obedient to Gu Yi is entirely because Gu Yi subdued them with salt, these primitive and barbaric species, and treated Gu Yi as a tribal leader and a Mao king.

Figure out what's going on, Gu Yi is called a sympathy, what kind of miserable life did these guys have before?

Anyway, this time there was a lot of brine clay, and Gu Yi was not stingy and used a small bamboo tube to fill some refined "ice brine snow crystals", and each person was given a tube as a reward for their hard work, but a group of "subordinates" were moved and couldn't wait to throw their five bodies to the ground.

But Gu Yi found that as soon as these guys got the reward, they poured it into their mouths and swallowed it without saying a word, almost fainting!

Nima~ These guys are going crazy!

No matter how delicious this thing is, can it just be poured into your stomach?

Looking at Bai Min, Rou Servant, Mao Ren and hundreds of mine subordinates, working excitedly with an almost pious attitude, Gu Yi was very satisfied.

No matter how good the gold gravel is, there will always be a day when it will be finished, and when he determined that it is feasible to make wine and salt, he immediately ranked the gold gravel as a reserve resource in the third sequence, and only used it as a short-term fund to buy grain.

After all, the gold panning project, the damage to the environment is quite large, they are just separated by a small section of the riverbed to pan for gold, has caused the nearby aquatic life to flee in all directions, if it is fully developed, it is estimated that this water-rich trap river will be abandoned, when they are still living in this natural cage-like broken valley, Gu Yi does not plan to do this kind of dry and fishing.

Fortunately, the basin of the Trap River is not too short, they are only separated by a few hundred meters of a rich alluvial area to mine, which will not cause much harm to the overall environment, and the underground river with a large amount of water will continue to bring a variety of aquatic organisms to supplement the ecosystem of the Trap River, but they are not worried that the aquatic products in the river will be extinct by them in a short period of time.

Because he didn't know about this world, it was difficult for Gu Yi to understand that these aborigines of this world were so fanatical about their work, even to the point of forgetting to sleep and eat, he only taught them a few times, these people were like performing some kind of sacred religious ritual, and they were doing their work one by one with solemn faces.

It took only a short time to refine all the brine they brought back into snow-white "ice brine snow crystals", until all the raw materials were consumed, and then they had to stop.

When the Bai people took the mine and excitedly held an altar of snow-white salt grains in front of Gu Yi, Gu Yi was speechless for a while, and the transaction will only be carried out in the monthly market next month, you have finished the work so quickly, what are you doing in the next twenty days?

After settling the accounts, the possible benefits of these "ice brine snow crystals" frightened Gu Yidu!

The so-called "brine earth" is a salt mud block obtained from the underground saline ore layer after drying the natural salt brine mud that gushes out of the ground through the cracks in the ground rock cracks, and this kind of thing cannot be used as an edible product at all under the conditions of this world.

Only those who can't afford to eat salt, the common people, in order to survive, use this highly salty mud to wrap large pieces of fish and meat for pickling, so that the food can obtain a trace of salt, or use water to dissolve it, and then precipitate, take the upper layer of salty water to cook, but the taste is not to be expected, fishy, smelly, bitter and astringent, with a strong earthy smell, so the price of brine is very low.

Tantalum (75. 6kg) brine mud is only two small gold cakes, ordinary people buy a tantalum, enough to use for several years, like Gu Yi's large-scale purchase, a one-time empty [Shuiwatun] brine shop all the brine clay, the price is even cheaper as if given away, a small gold cake can buy a tantalum.

For Gu Yi, whether it is brine mud, brine stone, or halogen crystal, there is actually no difference at all, anyway, it is all to be filtered, so it is the most cost-effective to buy cheap brine clay.

According to the calculation that one tantalum brine can filter out about fifteen kilograms of salt grains, that is, one-fifth, the 1,000 tantalum brine he bought this time will also filter out 15,000 kilograms of "ice brine snow crystals"!

But the price of "ice brine snow crystal", compared with the cheap commodity of brine mud, I don't know how many times the road has increased!

According to Gu Yi's business intelligence inquired from Nanwan Hao Shang Zhenning, at present, the entire [Zhongrong County] is located in a remote area and has not been affected by large-scale military disasters from other counties and provinces of [Zhongyouzhen], so prices are relatively stable, only slightly rising.

Although the price of strategic materials such as halogen and millet has risen slightly, compared with the outside world, it is much cheaper.

And in [Zhongrong County], there is still an average price of one gold and one hundred, which fluctuates slightly according to the distance from the grain-producing area, and the amount purchased by Gu Yi is large, and it can even be cheaper, and his four hundred grains of grain only cost three hundred and twenty large gold cakes, which is already very cheap.

A thousand tantalum brine only cost Gu Yi but fifty large gold cakes, a black halite but five small gold, a lower grade halide crystal a big gold, the middle grade ten gold, the top 100 gold, I heard that there are also such as "ice brine snow crystal" this kind of natural crystal clear and impurities of the top grade halide crystal, but it is extremely rare, usually only those Shicheng, Rongbao noble status, rich nobles can enjoy, but the price can not be measured by the price of gold.

With 50 gold brine clay, 23,800 pieces of "ice brine snow crystal" were "refined", and even if they were sold at the parity price of 500 gold, they could be sold at a terrifying price of 11.9 million gold!

How many times the profit does this have to be?

A mine with no personal freedom, but with a net worth of tens of millions, seems to make the scene too big?

Gu Yi, who was a little annoyed, rubbed his chin, squinted his eyes and thought about it for a long time. Bluestone Mine is... And maybe there are more predators behind them!

Before gaining a free identity and the ability to protect himself, I am afraid that he has to keep a low profile, large-scale production, mass production is obviously not feasible, although relying on the old dwarf under the protection of the tiger skin, but too public, I am afraid it will still bring them unpredictable danger.

Then he can only engage in hunger sales and take the route of high-level luxury goods, and he tosses these things just to improve his chances of survival, not to improve the living conditions of the people in this world.
