Qiao Xuejun asked, "Sister Li, how many fish skins have you tanned? Are they all like this?"
Sheep skin, cow skin, and rabbit skin can all be used to make clothes. However, when they are harvested directly from animals, they are all raw skins and cannot be used directly, otherwise they will deform, deteriorate, and stink.
Tanning is necessary to turn raw hides into finished hides. This is the case with all leather crafts.
Tailor Li hesitated for a moment and said, "Not too many. I just tried a few that were similar to this eel skin."
Qiao Xuejun said: "Then help me try something else to see if it can be tanned like this eel skin, making it soft, windproof and waterproof."
Tailor Li nodded and agreed: "Sure. Are you useful?"
Qiao Xuejun nodded: "Yes. The temperature is going to drop, so we need to build a greenhouse to keep the experimental field in the back warm. This is it, there is no tarpaulin."
"Yes." Tailor Li responded immediately, holding the fish skin in his hand, "This is suitable for making tarpaulin."
Qiao Xuejun: "Yes, it's just a little small."
Tailor Li said, "It's okay, little one. Just sew some seams. We have quite a few people in the tailoring room."
In the tailoring room, Tailor Li took in a few more female apprentices.
Qiao Xuejun: "I think if those large fish also have this trait, we wouldn't have to spend so much effort."
Tailor Li nodded. "Yes, there is a lot of work right now. All the people are laying stones for the defense wall outside. Blue oil production is also being stepped up, and a few more boilers have been added. They also need manpower."
Tailor Li's apprentice also said, "Yes, the patrol team went to the dormitory area last night to mobilize people. They said that they would form a salvage team in a few days and sail to the city to look for things. They asked everyone to sign up enthusiastically."
Qiao Xuejun had heard Zhao Xian mention this matter before.
Tailor Li said, "Fortunately, we recruited quite a few people this time, otherwise there would be no one to do these jobs."
Qiao Xuejun thought, no wonder the system has even come up with a way to use pheromones to promote reproduction. Now that there is no equipment, productivity can only rely on population size.
If there are not enough people, there will be no one to do the work and the work cannot be carried out.

Regardless of whether Tailor Li could find a larger fish skin to make a tarpaulin, eel skin would definitely work.
Now that we have a source for the tarpaulin, the next step is the beams and columns.
Qiao Xuejun went to find Zhao Yun.
Kuang Qianli was in Zhao Yun's workshop, where several people were holding pliers and screwdrivers, studying the mechanical exoskeleton on the table.
Qiao Xuejun knocked on the door: "Deputy Minister Zhao."
Zhao Yun and others looked up.
Kuang Qianli saw that it was Qiao Xuejun and smiled: "Qiao Qiao, why are you here?"
He even deliberately glanced behind Qiao Xuejun.
Qiao Xuejun knew what he was looking at: "Doctor Wang is out on a mission and is not here." Did he think they were here to visit him?
Kuang Qianli was slightly disappointed when he heard this.
Zhao Yun also greeted him: "Teacher Qiao came to see me?"
Qiao Xuejun nodded and got straight to the point: "I heard that the temperature might drop. I plan to build a greenhouse and I want you to help me draw up a design."
Zhao Yun frowned and said, "It's no problem to produce the drawings, but resources are tight recently, so I may not be able to do it."
He was afraid that Qiao Xuejun would think that they didn't take it seriously, so he went on to explain, "We have reached a deal with the Sea Fortress, but the steel they provided is not enough for the fortifications. We have to rely on the fishing team to find some ready-made ones to make up for it."
Zhao Yun was in a dilemma: "If the defense is not repaired, the experimental field will repeat the same mistake. So it's not that we don't want to build defenses for the experimental field, but we really don't have the materials and there is no other way."
After hearing what he said, Kuang Qianli said, "You really don't know our Qiao Qiao at all! She asked you to draw the picture. If you can do it, just do it. She has probably thought of everything else."
In Kuang Qianli's eyes, Qiao Xuejun has always been a very capable person. In the shelter, they are responsible for following Qiao Xuejun's orders, and Qiao Xuejun can basically handle all matters, big or small.
Qiao Xuejun smiled and said, "Indeed, we can stop using steel for now."
Qiao Xuejun stepped forward and said, "I plan to use wood as beams and frame supports, and then put tanned fish skin on it to imitate a greenhouse."
Zhao Yun was surprised when he heard this: "Tanned fish skin?"
Qiao Xuejun: "I just went to the tailor's room to check it out. It's pretty good. It's similar to plastic sheeting, very flexible, windproof and waterproof. I think I can give it a try."
Zhao Yun quickly understood: "Oh! That sounds good. Wood can also be used as support. It can also be made into a mortise and tenon structure without the need for nails and screws."
Qiao Xuejun: "Resources are tight, so I plan to build a greenhouse for the two acres of rapeseed land first. It will save some materials."
Zhao Yun made a rough estimate and said, "Let's look at the fish skin area. Five acres of land will definitely be enough for the wood area."
Qiao Xuejun: "Then you can help me draw a picture and mark the size so I can show it to Sister Li. We can make it as big as we can."
Zhao Yun: "Okay, tell me what else you plan to plant in this greenhouse? Do you want to make it multi-layered? I've seen greenhouses with multiple layers."
Qiao Xuejun: "Of course it's good to be able to do it, but aren't we short of materials?"
The several-layer ones that Zhao Yun mentioned are vertical planting farms. If the cultivation racks are made into two layers, two more plots of land can be superimposed on the original rapeseed, which is equivalent to directly expanding the land by three times, from 2 acres to 6 acres.
It is very suitable for growing some shallow-rooted and short crops, such as green leafy vegetables, such as lettuce and spinach, which can be harvested quickly and mature in one month, or fruits, such as strawberries and blueberries.
Zhao Yun: "You can use wood first. If it can't bear the weight, just make one layer."
Qiao Xuejun nodded: "If there are enough materials, we will do it."
Even if it's just one layer, that's double the land, enough to grow a lot of things.
Zhao Yun was very fast. He had finished the drawing by the time Qiao Xuejun came back from lunch.
Qiao Xuejun took the drawing and looked at it.
He designed a conventional arched greenhouse, with a total of four greenhouses.
The picture shows the detailed dimensions and shape of the tarpaulin, and even the required length and area of the tarpaulin (also known as the fish skin) have been calculated.
Qiao Xuejun: "You are quite fast."
Zhao Yun was very satisfied with the compliment: "Little greenhouse, sprinkle some water."
Compared to the design of the base, this small greenhouse is much simpler.
