Back to the era with space materials

Chapter 374 Finalized

Huo Lang turned back, gently pushed Si Ningning away, touched Si Ningning's head again, and said in a coaxing tone:

"I know, but this is what I want to give you."

"obedient."

"Well..."

The life-long event of the two of them was a matter of course. Si Ningning didn't think that because she was a girl, she would be looked down upon if she took the initiative to bring it up. However, after some hesitation and thought, she nodded.

Just wait and wait!

It's okay to wait.

Now that everything in the team is on the agenda, they can't spare the time to properly take care of their own affairs.

"I just woke up. Are you hungry? Are you thirsty?"

Si Ningning shook his head, "How long have you had lunch? How could you get hungry so quickly!"

Huo Lang smiled and raised his chin upwards, gesturing to Si Ningning to look at the sky, "You had a long sleep this time."

Si Ningning quibbled, "I just lie down and do nothing while sleeping. The food in my stomach has not been digested yet."

But she was indeed a little thirsty.

Si Ningning licked her lips subconsciously, but Huo Lang saw through her little moves, took her shoulders and turned her around, pushing her towards the main room, "There is brewed scented tea in the pot on the table, it should have cooled down.

, it’s a good time to drink.”

"You go pour it yourself, and I'll pull down two more boards, and we'll go make leather."

"Um!"

Huo Lang's arrangement pleased Si Ningning, so she nodded without thinking and trotted to the main room.

In the courtyard, Huo Lang looked at her reveling back and shook his head with a smile, bowed and continued his work.

At about 4:30 in the afternoon, Huo Lang finally finished his work and put down a series of tools such as the scroll saw and hammer. He washed the dust off his arms and face at the well, cooled down a little, and then waved to Si Ningning.

.

Pulling out a piece of bamboo tube at random, Huo Lang opened it with a hatchet, selected one-third of the width of the bamboo piece and kept it, and waved the rest aside.

He used a hatchet to shave one side of the bamboo slices, and roughly cut out a thin blade. He tried it by pinching it, and when he felt it was almost done, he took the rabbit skin out of the basin, turned it over and washed the side with the blood, flesh and grease.

Spread it out on the big stone:

"I learned this from my comrades a few years ago before I changed my career. I don't have to pay much attention to it. The first step is to soak it. After soaking, when the skin is softer, I use a bamboo knife like this or a similar stone piece to cut it.

The remaining oil, minced meat, etc. are all cleaned up.”

"This is a delicate job, and this step of the whole process is the most troublesome. If this step is not handled well, all other work will be in vain."

Si Ningning nodded, indicating that she was listening carefully again.

Huo Lang smiled and nodded, his hands were not slow, and while he was busy, he shared some knowledge with Si Ningning, such as:

Why choose to use bamboo knives and stones to clean the remaining minced meat instead of iron knives that are sharper and more controllable?

The answer is that even if an iron knife is severely worn, its hardness reaches a certain level, so it may not look sharp, but it is actually much sharper than bamboo chips and stones.

If it is too sharp, it will lose its fault tolerance, and it is easy to accidentally damage the leather during operation.

Si Ningning tapped the bamboo knife in Huo Lang's hand: "Most Chinese people are smart, let's just talk about this. How many times did it take to experiment and come up with this little trick and conclusion?"

Huo Lang shook his head and smiled lowly:

"People are smart, but experiments cannot be said to be the same. Like when we were lucky enough to catch something in the wild before, we used whatever we had on hand when making leather. If not, we should be particular about it."

"No matter what tool you borrow, you have to be careful when cleaning it. If you are half-hearted, even if you use your hands to press the minced meat on it, you will still hurt the skin."

Si Ningning nodded obediently and took Huo Lang's words to heart.

After soaking a small piece of rabbit skin, it takes only half an hour for Huo Lang to clean it. Today is to show Si Ningning the process of making it, so Huo Lang needs to be more careful while cleaning it.

While talking, by the time we got to the next session, it was already an hour later.

After rubbing the cleaned leather several times on the stone slab, Huo Lang went into the kitchen and shoveled out two shovels of plant ash.

The rabbit skin was opened, and two large handfuls of plant ash were sprinkled on it, rolled up, and rubbed repeatedly. "Plant ash can remove oil and also have a certain cleaning effect. It is best used to deal with oil slicks on the leather."

Si Ningning nodded, his little head was racing, and after a while he asked: "Plant ash contains alkali, so it can remove dirt and oil. If we only look at the alkaline content, can lime powder also be used?"

Quicklime is an alkaline oxide, and its main component is calcium oxide. However, after reacting with water and neutralizing it, it will turn into slaked lime, thus producing "alkali".

Whether it's duck down or rabbit skin, there are always some things that are in common with each other.

Si Ningning asked Huo Lang: "Do you need to soak the plant ash after rubbing it?"

"yes."

Si Ningning asked again: "Then how did you do it before?"

"Alum, plant ash, or salt, choose any one of these three and mix it with hot water. Let it soak for two to three days, then take it out and rinse it out before proceeding to the next step."

Si Ningning thought about it for a while. This step should have the effect of degrading the protein in animal fur. If this step is done well, the leather will be softer and there will be no odor when processed or worn in the future.

"Follow your original method, but add a little lime powder to remove the smell and sterilize."

Taste affects the quality of leather, and as for "bacteria", medicine is underdeveloped in this era. Si Ningning feels that "sterilization" must be strictly controlled.

Fortunately, there is such a good thing as quicklime, which is not only simple and crude in effect, but also extremely low cost, and can directly solve many thorny problems.

"Okay." Huo Lang agreed.

Duck down and rabbit skin are not things that can be dealt with in one go. Seeing that it was getting late, Si Ningning turned over the snakeskin bag that used to contain duck feathers and washed it clean, and finally put it in a corner of the backyard to dry.

After finishing these tasks, she clapped her hands and prepared to go home:

"I've been out for a while today, it's time for me to go back."

"I send you."

"Yeah. By the way, I'll come back tomorrow morning and have breakfast here then."

"Okay, I'm ready and waiting for you to come over."

Si Ningning nodded, and the two of them walked together. When they reached the literacy class, she turned around and waved to Huo Lang, "Just send it here. There is a dormitory ahead, and this road is very busy."

Hearing this, Huo Lang stopped and looked at Si Ningning in the blurred sky, running like a cunning rabbit into the path and disappearing.

Huo Lang stood there for a while, guessing that Si Ningning was about to reach the point of becoming an educated youth, then he slowly turned around.

He silently weighed and muttered in his mind:

Still missing a cabinet...

The attic floor and stairs also need to be replenished with tung oil on both sides. In the south, surrounded by mountains and forests, there are many termites, so we must take precautions in advance.

In the dead of night, Jiang Yue was lying on the bed, half asleep and didn't know if it was a dream or something. A long flight of stairs suddenly appeared in front of her. She raised her steps and was about to step over one, but when she stepped out, she stepped on nothing.

Douji Ling was awakened from his dream.

Jiang Yue sat on the edge of the bed panting with sweat on her forehead. After a while, she recovered and realized that Si Ningning on the opposite bed had not rested yet and was writing furiously under the lamp.

Jiang Yue wiped the sweat from her forehead, put on her shoes and went to the main room to pour a glass of water. When she came back, she was standing at the table, drinking water and watching what Si Ningning was busy with.

Si Ningning was recording the steps of washing duck down and cleaning rabbit skin during the day. After writing the outline, he wrote down a number of tips in the blank space below that he thought were feasible or could be replaced in a simpler way.

Jiang Yue could still understand the text, but there were several lines of letters below, and Jiang Yue could see the question marks in her head: "What are you writing here?"

"Aren't our teams going to raise rabbits? We should be able to process our own leather in the future. I'm now considering methods to see which one is most suitable for current implementation."

Jiang Yue nodded, "I know, this is what I'm talking about, what is this? It doesn't look like foreign writing."

She tapped her hand on the notebook. Si Ningning looked over and said "Oh" calmly: "This is a chemical equation. I wrote it casually. Don't look at it."

While recording just now, Si Ningning suddenly came up with the idea, could they try to make sterilizing detergents, bleaches, etc. at the lowest cost?

But after a rough calculation, I found that I may have too few things on hand. To prepare what I need, I have to make the same formulas, do experiments to extract them, and then collect them...

Not only is it tiring, but it’s also a waste of time, so after thinking about it, I decided to forget it first.

Everything is in its infancy now, so it’s not good to spread the business too far, otherwise it won’t work, and it won’t just be her time and energy, but everyone will have to follow her.

Just focus on the present.

"You really can't take any time off. It's rare for you to take two days off, but I haven't even seen you take a break."

"I'm taking a rest right now. I'm just sorting out these things and playing around with them to pass the time."

Jiang Yue spoke loudly. If she hadn't known about Si Ningning's character, she would have almost stopped talking to Si Ningning.

Having said that, it seems like this happens every time?

Si Ningning said that whatever you mess with will eventually shine...

Jiang Yue couldn't help but sigh in her heart:

The difference between reading more and reading less is really big. For people like Si Ningning who are excellent in stages, it would be difficult for her to catch up with her even if she whips her horse and rides a horse.

Reading is really important!

People who are poor need to study, and people who are ugly also need to study. People like her who are mediocre and have no family background should study even more!

Jiang Yue clenched her hands into fists in front of her chest. Si Ningning glanced at her from the corner of her eye, wondering why she suddenly became excited.

"Did you have a nightmare just now?"

"No, it's all trivial, so don't mention it."

Jiang Yue waved her hand, took two books and sat down in front of Si Ningning.

Si Ningning's hands clearing the table paused slightly, then raised his eyes and asked her, "What are you doing?"

Jiang Yue shook the book in her hand, "Read a book!"

"Don't sleep anymore?"

"Go to sleep later! Wait until I finish reading these two pages!"

Jiang Yue's attitude was firm, so Si Ningning did not disturb her. After packing her things, Si Ningning opened the mosquito net and got into the bed. Occasionally, she would say a few words to Jiang Yue and remind her to go to bed early.

During the rest of the time, Si Ningning was thinking silently.

Zhao Hongbing is a philanthropic person. He does everything he decides to do well. He always treats the children, teachers, and members of the team with clear rewards and punishments, and the intensity is not small.

But, if there is no progress in the rabbit farm, how long can this arrogant reward and punishment system be maintained?

Although the rabbit farm is busy every day, the actual promotion is really very small.

Si Ningning knew the reason.

First, it’s the second half of the year again, and the time for storing fodder is limited. You can still take care of it when there are few rabbits, but not when there are too many.

But rabbits are so good at giving birth.

The second is the problem of processing leather.

Si Ningning has never given a clear explanation. Even if Zhao Hongbing believes in her and supports her, there are still many people in the production team who are in a wait-and-see attitude. These people are worried about gains and losses, and are afraid that their hard work will be in vain, so they act as role models when they work.

A foreign worker.

Zhao Hongbing will motivate these people, but as the captain of the production team, he has many responsibilities and things to do, and he is not covered with eyes. There are always things he cannot take care of.

Si Ningning rubbed her face against the pillow, becoming more and more determined to finalize this leather-making technology as soon as possible.

"Ning Ning?"

"ah?"

"I'm going to bed, do you still use the light?" Jiang Yue asked.

Si Ningning responded in a low voice: "No, I'm sleepy too, just blow it!"

"good."

Early the next morning, Si Ningning finished washing and put her things back in their place. Just like yesterday, she put on her water bottle and small satchel and went out to Chen's house.

Huo Lang had prepared the meal early as promised.

Breakfast was nothing special, just a big pot of multigrain porridge and four eggs. Si Ningning came over and remembered to see the duck down and rabbit skins, but Huo Lang quickly pushed him to sit down at the table.

Huo Lang divided the eggs, and there were four eggs for each person. "Eat first, and then look at it after you finish."

"Oh, okay."

Si Ningning took the egg and knocked it on the edge of the small table. After peeling the shell for a while, he couldn't help but ask: "Have you checked today? Are there any changes? Rabbit skin needs to be soaked for several days, so it won't be visible.

What's that? You can always tell something about duck down, right?"

Huo Lang nodded first, then shook his head, "I looked at it, and the duck feathers were all lumped together in the water, and I couldn't see anything."

"ah?"

Si Ningning was a little disappointed, and then Huo Lang added breathlessly: "But one thing can be confirmed, the lime water should be effective, and the duck feathers do not smell so fishy."

"real!?"

Si Ningning's deer eyes lit up for an instant, this was considered excellent news.

"I'll eat it quickly. I'll go over and take a look later. If there's no big problem, I can take it out today and let it dry and then check the situation!"

"OK."

Huo Lang nodded in agreement, and calmly peeled off the plum blossoms in his hands and pressed them into his mouth. The white and tender egg whites were conveniently placed in Si Ningning's bowl.

The author has something to say:

A few days ago, I was supposed to update it stably, but after three years of prevention, I still couldn't prevent it. I suddenly became Y, and I was stretched out on the bed for seven days. Now I don't feel so uncomfortable, but I still often feel dizzy...

It’s so painful! The little cutie who hasn’t had sex yet must be protected!
