Returning to hometown to farm: The apocalypse system arrived ten years earlier?

Chapter 12: The Best Sword
"Young man, how do you want to fight?" Master Lei asked Li Xiang enthusiastically.

Li Xiang then stated his request, asking that the old axe, sickle, axe, pickaxe, etc. that he had brought with him be repaired by adding some of this steel.

If there are any extra ones, I will help him make a high-density knife. Master Lei will know the length, size and shape after just a few words.

So, start cutting materials and get to work.

Master Lei has an electromagnetic high-frequency induction melting furnace here, and he threw the cut steel blocks into it. Although the "Rock Breaking Roller" special steel is known as the Rolls-Royce of steel, it is extremely hard and has a high melting point, but once it enters this furnace, it quickly turns red like fire.

Master Lei said with some pride that this furnace was newly bought by him and it has very good performance. It is currently the most efficient and fastest induction heating equipment for heating metal materials, and it is low-consumption, energy-saving and environmentally friendly.

After heating, Master Lei clamped the steel block out with a clamp and placed it under the air hammer for forging!
Air hammer is a kind of free forging machine. The compression cylinder compresses the air and sends it into the working cylinder through the distribution valve, pushing the piston and the hammer head to move up and down to hammer. It is flexible to operate and can extend, upset, punch, shear, forge, twist, bend, etc. It is especially suitable for forging small and medium-sized forgings.

During the process of leveling the steel, Master Lei kept praising the material for its excellence.

"It only takes me a few minutes to make other steels, but it takes me three times as long to make this one."

After beating the special steel into the required shape, Master Lei removed the wooden handle of the old hatchet, heated the raw iron red, and then hammered it under an air hammer.

It is much easier to forge this iron, and it can be completed in less than a minute.

Afterwards, Master Lei used the steel clamping technology to add steel to the cutting edge.

This is one of the important techniques in sword forging.

Qi Jiguang recorded in Jixiao Xinshu: "The method of making a waist sword is to refine the iron more and use pure steel for the blade."

Song Yingxing's book "The Exploitation of the Works of Nature" states: "The most beautiful swords are made of steel that has been tempered a hundred times, but the inside is made of iron. If it is not steel on the outside and iron on the inside, it will break when strong force is applied."

In other words, a good sword needs to have a core of tough wrought iron. After being heated, it must be repeatedly forged and tempered with a sledgehammer to remove impurities, and steel must be poured into the blade so that it can cut iron like mud without breaking under stress.

Li Xiang also filmed the entire process with his mobile phone as material for a short video.

When Li Xiang didn't understand something, he asked Master Lei.

Master Lei is a good teacher. He taught Li Xiang what annealing, tempering, and quenching are... These are all means to improve the toughness, hardness, stability, and wear resistance of the device blank.

Although the "Rock Breaking Roller" special steel is outstanding, its yield strength can reach a terrifying 1200 MPa, while the yield strength of general special steel is 600 MPa. It can be said to be a super steel among special steels.

However, in the process of forging knives, if you don't master the skills of annealing, tempering, quenching, etc., you can still produce junk products. Especially when it is mixed with ordinary wrought iron, the requirements are even higher.

Master Lei has all the tools and is very experienced. In less than an hour, he had refurbished all the old tools Li Xiang brought, and there were still more than 50 kilograms of special steel for the "rock-breaking hob" left.

This piece of steel originally weighed more than 70 kilograms. It was heavy but small in size, so relatively less material was used to repair those old utensils.

Even so, those old utensils were fused with super steel, and their weight increased greatly, making them unsuitable for grandma to use. But with Li Xiang at home, why would she need grandma to do rough work?
"There is still a lot of material left. To make a high-density knife, according to the size you just mentioned, it will probably take ten kilograms. What else do you want to make?" asked Master Lei.

Li Xiang pondered for a moment and said, "How about making the Gaomi knife bigger, thicker, longer, and wider, and making a 30-kilogram knife. For the rest, I can make a kitchen knife and a three-pronged steel fork. I'll take the rest back with me."

Because if there is any damage in the future, the excess material can be used for repair. Master Lei rubbed his ears, thinking he had heard wrongly, and quickly confirmed: "Young man, are you sure you want to make a 30-kilogram high-density knife? It should be 30 kilograms, not 30 catties? Don't do nothing and end up working yourself to death."

Thirty kilograms, how many times can an average person swing it for work? If you sprain your waist, wouldn't it be a loss?

Even if it was fifteen kilograms, no, ten kilograms, Master Lei still felt it was too heavy. A knife for work weighed three or four kilograms, which was already quite good. An ordinary hatchet was only one or two kilograms. A smaller one might even weigh less than a pound.

Li Xiang smiled faintly and said, "It's okay, I can swing it."

Master Lei shook his head like a rattle to express his disbelief.

Li Xiang took a deep breath, picked up the remaining fifty kilograms of material, tossed it back and forth in his hand, dancing with one hand. Oh my god, Master Lei was stunned!

He has now reached the first level of the extraordinary realm. To be honest, a 30-kilogram weapon, no, a chopping knife, can only be said to be barely handy. When his realm is improved in the future, he can use heavier weapons.

Thirty kilograms, or sixty pounds, is about the same weight as Lu Zhishen’s Zen staff.

Of course, Lu Zhishen’s staff is made of wrought iron, while this one is made of super steel, which has a high density and a smaller volume.

Master Lei never expected that Li Xiang, who didn't look very strong, had such great strength, so he didn't say anything more and made a full-steel Gaomi knife according to his requirements.

Even the handle is steel.

Li Xiang planned to go back and wrap a hemp rope around it to prevent it from slipping.

After quenching, Master Lei uses a new V-neck sharpening method. After sharpening, he gently scrapes the whetstone, and suddenly a melodious, dragon-like sound is heard, which lasts for a long time.

"Good knife!"

Li Xiang weighed it in his hand and was very satisfied. With this high-quality Gaomi knife, he no longer had to worry about the blade bending or cracking when cutting bamboo. That's one blade per bamboo!
Then the three-pronged steel fork and kitchen knife did not use much steel, one weighed five kilograms and the other only 500 grams.

The main thing is that my grandma also needs a kitchen knife. And it's just for cutting vegetables, so it doesn't need to be too heavy.

As for cutting bones, is there any bone that this Gaomi knife cannot cut?

Since Li Xiang was recommended by someone he knew, Master Lei gave him a discount and charged him 500 yuan for the processing fee, because Li Xiang brought all the materials himself.

Master Lei also gave him a green charcoal whetstone.

Li Xiang found a store nearby and bought a cutting machine, electric saw, electric drill, wire, nails and other items. Then he went to the market to buy ten kilograms of spare ribs and rode his tricycle back home. If he didn't go back, it would be dark.

"It costs a lot of money to come to the county town, and the financial pressure is huge!" Li Xiang hopes to save more money so that he can stock up enough supplies. When the end of the world comes, supplies, especially food, are the most precious.

After he went back, he started editing videos on his mobile phone at night. No matter what, he would just post one episode first.
