survival system

Three days have passed, the roof has been built, and the weather has become significantly colder. The cold wind will make people shake a few times.

The system also notified Yuanlu that he had learned the "wooden mortise and tenon technology" in architecture and gained [-] points.

It is also good to have the roof on the first floor. Yuanlu and the others built the door. The gaps in the windows were sealed with various limited materials, so that the cold wind would not flow into the entrance and exit to the basement. Even the first floor was okay. Let people move around and not just stay on the first basement floor.

The results of the soaking of the animal skins have come out, probably because the concentration of plant components has increased after the mutation, the animal skins that may have been soaked for a long time were softened in advance, and then Yuanlu and the black peanuts washed the small pieces of skin with Sapindus sativa, and waited. to dry.

Because Uncle Lingyuan is a "special race", and because his two sons said that their food and other distributions will be divided into three portions from the two allocated to the uncle, the exchange uncle does not need to go out to collect and hunt, but he does not want to let the uncle His physical condition deteriorated, so the uncle became the only idler in the base.

And this idler observed everyone in the base for a few days, and finally decided to follow Yuanlu every day, because only Yuanlu did the most interesting things.

This day, I also squatted aside to observe Yuanlu and Hei Huasheng making animal skins.

"You use plant vacuoles to soak animal skins?"

"En." There was only a small piece of animal skin the size of a square scarf, and Toru still cleaned it very carefully.

"Why not use alum? The tanning speed is fast, and the tanned animal hides are more durable." The uncle said that he used to have a travel friend who was very interested in that kind of mountain affairs. He would tan the prey skins obtained by hunting himself. The uncle roughly talked about some processes.

"Alum? Can it also be used to tan leather?" Yuanlu asked.

"Of course, Uncle heard it from a friend. I've seen him do it many times."

"But we don't have alum, and it has to be found near volcanic rocks. We don't have volcanoes here." Yuanlu thought about the special collection of minerals in Encyclopedia that he had read before, in which alum was introduced.

The system began to update the information because of the conversation between the two, and encouraged Yuan Luduo to extort all kinds of knowledge and experience from Uncle Lingyuan.

"It's a pity." The uncle said, but he was also very interested in seeing Yuanlu and Black Peanut's approach, "Do you want to tan next time? I can help! Otherwise, you are all adults, and you children will have to raise them." , what a shame!"

"Okay! These pieces are for our experiments. In fact, I think they should be successful, so I plan to take them to the sun and start to deal with the pile of dry and hard animal skins in the corner of the first floor." Yuanlu considered what if If you make it slowly, you may not be able to use it in winter, so you must speed up. It is always good to have someone to help.

The two moved faster. After washing all the furry animal skins, they took them to the first floor to dry outside. It is always faster to dry in the sun.

Then the three of them stood on the large pile of animal skins that exuded a disgusting thick fishy smell, and Uncle Lingyuan couldn't close his jaws in surprise for the time being.

"so much?"

"Well, these have been accumulated before I came here, and the treatment before soaking in the plant liquid is quite troublesome, but then I asked everyone to remove the fat and connective tissue after cutting off the animal skins, and the fat is still there. It can be used for frying or lighting a fire, etc., and it cannot be wasted, so it will be less likely to spoil if it is used in the sun.”

"Okay! Looks like this job won't be easy anymore! But it's okay with the uncle here! Let's do it!"

"Well, the animal skin needs to be soaked in water to soften it first. It's very convenient to carry water now, so let's do it on the first floor! The smell is so strong that everyone can't sleep at night."

For the follow-up part of the small piece of animal skin, Yuanlu also explained the general steps to Hei Huasheng, and Uncle Lingyuan also added some details, and finally made the steps of tanning the leather clearer.
