survival system

"Ding, the task is completed, reward [-] point. After the system finished speaking, it changed the content of the identification, "Rose rock salt, can be used for cooking, rich in iron and trace elements. 』

In the future, if Yuanlu can find the same thing, even if it is white or orange, he will know that it is rose rock salt after taking pictures for identification.

Because there are still many bags of sea salt in the base, this beautiful rose rock salt was received by Yuanlu as a collectible.

Turn around and continue to bring black peanuts to prepare the animal skins for the next work. The grasses that have just been classified, except for the herbs that can be used for medicine after identification, Yuanlu ordered Siyi to deal with them. Fresh herbs are not easy to preserve, so wash them clean Finally, it should be spread out to dry, and then stored directly.

And another pile of weeds or unripe fruits with bad taste have already been sorted.

"Do these weeds have anything to do with the processing of animal skins?" Black Peanut asked curiously.

"Well, there is a next step. We need to use a plant ingredient, which can soften the leather. The treated animal hide will be soft, wear-resistant, not easy to rot, and will not be so heavy. stench."

"Then why do we classify these weeds?" Black Peanut felt that this seemed unnecessary.

"Because I don't know which plant contains more ingredients that soften the skin, so I did the experiment."

Yes, Yuanlu remembered that the ingredient was tannic acid, but he was a bit vague about the treatment method. He knew that the plant should be soaked in water, and after the ingredient was released, soak the skin in it, wait for a while, and wash it off. After drying, oiling is applied to complete the tanning process.

However, the environment has changed so much now, and the plants are more or less mutated, so he doesn't know which plants have more tannin, and he also remembers that when using tannin to soak the skin, it is necessary to start with a low concentration. Only when the concentration is high can tanned leather be better.

All these concepts are told to Black Peanut, hoping that he will keep them in his head. In the future, at the base, there will be one more talent that can make people pay more attention to him.

Black Peanut thought it was amazing that the tannic acid that Yuanlu said would be contained in the water after the plants were soaked in water, but when he saw Yuanlu divided the same plants into two piles, he started scratching his head again, unable to figure out how to do this Why, but he remembered that he had asked a lot of why just now, and he was afraid that Yuanlu would get impatient and suffocate him if he continued to ask.

Seeing Hei Huasheng's expression, Yuan Lv found it funny, "Ask whatever you want."

"Well, why are the same items divided into two piles?"

"Because I want to know whether hot water or cold water is useful for plant extracts." Yuanlu is not sure which state the plant releases a higher proportion of tannins, so the same weed is divided into two parts.

This is how the experiment started. The two of them managed to get together six small pots. Fortunately, they lived in a restaurant with a kitchen attached, and some pots and utensils.

Because it was an experiment, and there were not enough weeds, Zai Yuanlu took the black peanuts and took the animal hides soaked in water, leaving the hairy side unmoved, and the fat, remaining subcutaneous tissue, After the meat dregs, fascia and connective tissue are cleaned with a knife, wash the hairless surface with sapindus chinensis, mainly to saponify and remove the remaining oil, then cut into square palm-sized pieces, soak until Soak the plant liquid with hot and cold water respectively, and then wait for time.

"How long will this soak?" Black Peanut asked, looking at the animal skin soaked in the light brown liquid, feeling a sense of accomplishment.

"I'm not sure, because I don't know how much of those ingredients are in it, so I'll observe it in a few days." Yuanlu thought for a while, what should I look like when the tanning is completed?Have to think about it.

The tanning won't be completed soon, vegetable tanning will take some time, during this time, apart from Tangning asking everyone to find a way to open the twisted and jammed elevator doors on the floor where they live, the base Everyone had to spend two hours practicing martial arts at night, and spent the day looking for food and hunting outside.
