After Yuan left with the deer tribe hunting team, Tomoya turned around and went to work, as a leader, he needed to lead by example.

Su Yan also had to get busy, he needed to purify the impurity salt that he had traded from Yuan's hands.

Unpurified impurity salt is very difficult to eat, anyway, Su Yan can't eat it, Zhi can't accept it for the first time, I'm afraid that only after understanding the benefits of eating salt, will he endure the peculiar smell of edible salt.

What Su Yan needs to do is to purify the impurity salt and turn it into a snow-white fine salt, and the peculiar smell of the impurity salt will basically be expelled.

The method of purifying impurity salt is very simple, Su Yan found two large pottery bowls that can hold one liter of water.

First, a pottery bowl is filled with about one liter of water, and then all the impurities of about four taels of impurities from the transaction are poured into the pottery bowl, and the impurities slowly dissolve in the water, and the impurities sink to the bottom of the water or float on the surface of the water.

Salt dissolves into water, here we need to consider a solubility problem, about 100 grams of water can dissolve 36 grams of salt, with a liter of water to dissolve four taels of impurity salt.

After the impurity salt is completely dissolved into the water, the impurities in the brine need to be removed, and the removal method is very simple.

Take a slightly thicker straw rope, put it on the edge of the pottery bowl and stick it, the straw rope and the edge of the pottery bowl should not leave a gap, and then pick up the pottery bowl with salt water and slowly pour the salt water into another pottery bowl from the side of the straw rope, so that it can be easily filtered.

If one filtration cannot remove all the impurities, filter it several times until you get a brine with almost no impurities.

Then put the clay bowl with salt water on the stove, add firewood to burn the clay bowl, let all the water in the clay bowl evaporate, and finally what is left is fine salt that has no peculiar smell compared to impurity salt.

In the evening, Su Yan harvested less than two taels of fine salt, and Su Yan carefully put it away.

In the clearing, a fire appeared, and it was time to make dinner.

Last spring and summer, the men used to cook dinner, but now the work has been given to the women, who stick the fish together and put them on the fire.

Su Yan went over and brought a fish weighing more than two catties, he put the fish on a stone slab, and then took a stone chip and scraped it fiercely on the fish, scraping off the scales on the fish little by little.

After most of the scales on the fish were scraped off, Su Yan sprinkled a little salt on the fish, and then came to the fire and personally put the fish on the flame for barbecue.

It didn't take long for several female clansmen who were in charge of grilling fish next to the fire to turn their eyes to the grilled fish in Su Yan's hand, and they could smell a different smell from the fish they had grilled themselves, it smelled good, and they sniffed their noses.

People farther away will not be able to smell the aroma of Su Yan's grilled fish, which has spread along with the smell of other grilled fish.

There are no fish scales on the fish, and the roasting speed is a little faster, and when the fish is about to be cooked, Su Yan sprinkled a little salt on the fish again, and even Su Yan himself couldn't help swallowing his saliva.

After the fish was thoroughly cooked, Su Yan couldn't wait to eat it by the fire, but fortunately, before it was time to eat, the clansmen had not yet gathered, and Su Yan didn't want to see the clansmen looking at him greedily...... of grilled fish.

Soon, Su Yan devoured a whole grilled fish, and licked the corners of his mouth after eating, as if he was reminiscing about the taste of the grilled fish he had just eaten.

When the clansmen's dinner was ready, the clansmen gathered to prepare the meal, and they came to the fire one by one to take the food in the order of adult men, adult women, children, the elderly, and the disabled.

Su Yan picked up a grilled fish weighing more than a pound from the fire, sprinkled a little salt on the fish, and put it into the fire to roast it slightly, so that the salt quickly melted into the fish.

Holding the grilled fish, Su Yan came to Zhi, who was sitting on an earthen brick and was gnawing on the fish, Su Yan handed the grilled fish to Zhi, and said, "Taste it, it's delicious." ”

Zhi took Su Yan's grilled fish suspiciously, opened his mouth and took a bite, as soon as the fish entered his mouth, Zhi felt that this fish was very different from the fish he ate before, Zhi didn't know what "fragrant" was, he only knew that the grilled fish Su Yan gave him was more delicious, and Su Yan, who was devouring it, ate all the grilled fish he ate.

"Oracle, anything else?" Zhi licked the corners of his mouth and asked Su Yan.

"Yes, give me your fish."

Zhi handed over to Su Yan a grilled fish that he had eaten nearly half of the fish in his hand and had not eaten, Su Yan took the grilled fish to the fire, under Zhi's gaze, Su Yan first roasted the two grilled fish in the fire a little, added a little heat, and then Su Yan took out a small bag with fine salt from his body, grabbed a little salt with his hand and sprinkled it on the fish, and then put the grilled fish into the fire and roasted it before handing it to Zhi.

Zhi tried to take a bite of the grilled fish he had just eaten, and felt that the taste of the grilled fish was similar to the grilled fish that Su Yan gave him just now, and Zhi was happy to eat the grilled fish.

Zhi was only the first, and then Wu, Derpy, Adoptive Mother, Xiaohua, and Satsuki all tasted the taste of grilled fish with salt.

Zhi, Wu, and Derpy are because of their identities, and their adoptive mother, Xiaohua, and Xiaoyue are because they have the closest relationship with Su Yan, so they can eat grilled fish with salt.

The amount of fine salt in Su Yan's hands was limited, and it could not support the entire tribe to eat grilled fish with salt, but only a few people.

Su Yan didn't know when he would come to the snake tribe to trade salt again, maybe the snake tribe should also look for salt carefully, the deer tribe can find salt, and the snake tribe can't find salt.

Zhi also found it hard to believe that what Su Yan added to the grilled fish was the salt that was traded from Yuan today, and it was not absolute, there were many impurities in the salt that was traded, and the salt added to the grilled fish now was fine salt that had been purified, and there was a big gap with the impurity salt.

Su Yan also told Zhi that adding salt to roasted animal meat would also make it more delicious.

Hearing Su Yan's words, Zhi decided to go out hunting with the hunting team tomorrow, and he wanted to taste the salted roast beast meat.

In addition, Tomoya saw the importance of salt, although it is not known that salt can maintain physical strength, but salt alone can make food taste better.

The snake tribe is no longer short of food, and the pursuit of food is naturally developing in the direction of better taste, so Zhi decided to get more salt in the future, and be able to trade some salt with the tribe of the edge, and it is best to find the origin of salt by yourself.

Zhi already knows what salt looks like and tastes like, and if he encounters salt, he will definitely be able to recognize it.

The next day, Zhi returned with a hunting party with the carcass of a leopard, and in order to hunt the leopard, another member of the hunting party was slightly injured.

The roast beast meat with salt is really more delicious, and the amount of intelligent food is so large that even the Xiaohua Xiaoyue sisters can eat it.
