I learned skills in a different world

The armaments and weapons were shoddily made and could not be used on the battlefield. The soldiers' uniforms were only a thin layer of catkins and did not keep them warm at all. Under these circumstances, it became increasingly difficult for them to fight the Humang people.

They all felt chilled by this situation, but they knew that they could not lose or retreat. Behind them were their relatives and the people of Wei.

When Lin Feng and Shen Fangshi discovered new high-yield grains, they were very happy. If they wanted to be free from the control of the imperial court, Yuchengguan must be self-sufficient.

Therefore, the importance of potatoes to them was far beyond Shen Fangshi's imagination. After all, he only learned about the lack of food at the border from system tasks and Lin Feng's mouth. He did not know that the Wei army's difficulties had reached this level.

"General Li, the snow is falling so hard, can the people's houses bear it?" The snow showed no sign of decreasing, and Shen Fangshi was a little worried.

Li You didn't expect that Shen Fangshi could still think of this, and admiration flashed in his eyes.

"Don't worry, it snows heavily every year in Yucheng Pass. The people's houses are very solidly built and generally won't collapse. Even if they collapse, we will immediately send troops to rescue. The people are also very experienced in dealing with snow disasters."

Since Chu Kui guarded the border, he had all the power in Yucheng Pass.

Even though Yuchengguan was not wealthy, he managed Yuchengguan in an orderly manner, with strict military discipline and strong cohesion between the army and the people.

Then, Li You curiously asked casually: "Aren't the houses in your Linjia Village not collapsed by the weight of snow?"

Shen Fangshi was startled, and quickly lowered his eyes and lowered his voice, "...it seems like I didn't go out very often before, so I didn't pay much attention to this."

Li You regretted it as soon as he said it. Linjia Village was almost completely slaughtered by the Hu Mang people, and all Lin Gu's relatives were killed. Didn't he cause people sadness?

At this time, seeing Shen Fangshi's seemingly sad expression, Li You felt even more guilty, "Hey, I, Xiaoten, am really sorry."

"It's okay, General Li, don't worry about it. I feel relieved knowing that the heavy snow will not cause too serious a situation."

Seeing Li You apologizing to himself, Shen Fangshi felt slightly relieved.

It seemed that he was not vigilant enough. The original owner Lin Ku was from Yuchengguan, but he did not have much memory about these things. He naturally ignored them, but how could most people not be familiar with the place where they had lived since childhood.

Fortunately, this time, I could just say a few words to make things right. If I say something I shouldn't have said without thinking next time and expose my flaws, the consequences would be disastrous.

Shen Fangshi reflected on it, thinking carefully about whether there was anything he had missed before that he had not noticed.

After Li You left, Lin Feng and others also got up. They were a little worried when they saw the heavy snow. They couldn't wait for breakfast and ran to the potato field.

Shen Fangshi finished his breakfast slowly. There was not much variety in the food. Breakfast was only sweet potato porridge, but Shen Fangshi added Lingquan water and it tasted good.

Shen Fangshi didn't have a separate room now, but unlike Lin Feng and the others, he stayed in the fields all the time during the day. Lin Feng and the others knew that Lin Gu was practicing carpentry so that he could inherit the family business, so they didn't bother him. After Chu Kui knew about it before, Shen Fangshi was also given a set of carpentry tools.

Therefore, he could take classes in his room during the day. He wanted to learn basic carpentry skills as soon as possible.

Shen Fangshi went back to bed and lay down. Occasionally, Lin Feng and the others came back and saw him sleeping. They thought he was in poor health and wanted to rest more so as not to wake him up.

"If you want to be good at carpentry, you need to be proficient in using various tools. We use many, many tools when doing carpentry work. Today we are going to learn one type of carpentry tool, the saw."

Shen Fangshi listened with great interest.

I saw the carpentry teacher pointing to the saws on the table and introduced: "Saws are divided into wire saws, large straight saws, small straight saws, and round eye saws. The main methods of using saws are cross-cut saws and straight saws. Type, horizontal material is sawn wood horizontally, straight material is sawn wood vertically...

This strip saw blade is also called a "saw blade". It is a frame saw. It is fixed with bamboo clips. The tightness and angle of the saw blade can be adjusted. Frame saws can be divided into three types: coarse, medium and fine according to the length of the saw blade and the tooth pitch. "

Every time the teacher talks about something, he will point to that part of the saw and explain in detail.

“粗锯锯条长650—750mm，齿距4—5mm，主要用于锯割较厚的木料；中锯锯条长550—650mm，齿距3—4mm，主要用于锯割薄木料或开榫头；细锯锯条长450—500mm，齿距2—3mm，主要用于锯割较细的的木材和开榫拉肩。

You need to know these by heart so you know which type of saw to use when making different utensils. "1

Shen Fangshi carefully noted down the characteristics of different types of saws and decided to try them later.

By the time Shen Fangshi finished his class, only an hour had passed in reality.

After he decided to make a wooden repeating crossbow, he practiced many times in the space simulation room.

After his hands were no longer rusty, he planned to slowly start making crossbows. With the tools Chu Kui sent him, he also taught himself several basic carpentry skills, and he planned to try his hand first.

What Shen Fangshi wants to do is an arm crossbow. This crossbow is light enough, highly maneuverable, and has an effective range of up to 400 meters. It also incorporates modern technology, which can not only be used for defense and ambush, but is also lethal enough.

However, the performance of the crossbow material has a considerable impact on the power exerted.

The metal crossbow frame is better than the wooden crossbow frame, and the crossbow body can also greatly withstand tensile force. However, given his current conditions, he can only choose cheap and easy-to-obtain wood.

In addition to the crossbow body, crossbow arrows are also very important. Crossbow arrows are divided into three parts: arrows, arrow shafts and arrow feathers. The arrow shafts can be made of light and tough bamboo or wood, while the arrow feathers are made of the worst goose feathers.

But the arrows cannot be careless. Shen Fangshi can't find the right metal now. Even if it is available in the system mall, he will not buy it. The source cannot be explained, and he might be regarded as a spy.

Therefore, Shen Fangshi planned to replace the arrowheads with hard wood first. After the crossbow was made, he would take the sample and let Chu Kui, the general, solve the material problem.

And the lethality of this crossbow was not strong enough. Shen Fangshi decided to improve this crossbow into a bed crossbow and a cart crossbow after learning more woodworking knowledge. In this way, its power and range would be greatly increased, whether it was for siege or It can play a huge role in defending the city.

Now that the wooden repeating crossbow was almost completed, Shen Fangshi picked up a small component and began to install it according to the drawings.

He has practiced this step many times in the space simulation room and is already very skilled at it.
