Cultivation of Immortals starts from the blacksmith shop

Chapter 5 Building a Self-Defense Knife
Thousands of sunset clouds fall, and the cold night drives away the scorching sun.

A thousand houses light a fire, and thousands of houses float in smoke.

The road is already sparse, and there are not many pedestrians left. Occasionally, passers-by are in a hurry, leaning against the corner with their heads bowed and walking quickly.

Stores are also closing their doors.

There is no curfew in Chiba City, but in the midst of troubled times, thieves rule at night, so ordinary people dare not go to the streets casually.

Lu Qi lowered the curtain of the blacksmith shop, leaving only the chimney open.

cuckoo~~
Lu Qi's stomach growled again.

He rubbed his belly and frowned, "It's not long since I finished eating, I wasn't full, but now I've made a breakthrough, my body needs more nutrition and energy, and I'm actually hungry again."

Although he was hungry, the only thing Lu Qi could eat at home was the bark, so he could only endure it.

Looking at the iron materials in the warehouse, Lu Qi's eyes were firm.

This is the basis of his fortune.

Li Mu'er was sent to guard the gate, while he was planning to work for tonight.

"Ten low-grade knives were made in seven days, five during the day and five at night, almost two knives a day and one night."

"I don't count the daytime. I can only use two hours at night. If it is too late, it will affect other people's rest, and it will definitely attract people's hatred. It may also attract the yamen servants and neighbors, and there is a possibility of exposure."

"That is to say, within two hours, I will complete a knife and create some things that I need to sell."

Lu Qi recalled the scene of forging a low-grade dagger today, and thought about how proficient in blacksmithing skills he had become in the past half a month, and that he was already a master, and he was also a master of leather refining in the first level of martial arts.

In fact, it only takes half an hour to make a low-grade knife, and a quarter of an hour to polish it, and the remaining half of the time can be used to do his own work.

"With my strength, if I sell things and don't want to expose my identity, I can only go to the dark workshop secretly operated by the Lu family and the county government. When I was young, my father took me there several times, so I don't need to expose my identity." The sale of status."

"However, the order inside the dark workshop is good, and the order outside is still very chaotic. If I don't want to be targeted, I must sell things that match my strength. I need to show the strength of the first level of martial arts, and I can sell it at that time." There are only low-grade swords."

Lu Qi squeezed his chin and thought, "Besides, the sales can't be too good. It's better to be just qualified. In this way, it won't show off the mountain. And low-grade swords have never worried about buyers, especially now that Judaomen To develop new mine veins, the recruitment of new people in the second half of the year is about to start, too many people need weapons at hand."

When Lu Qi thought about it, he began to care.

"However, I have to guard against some poor and crazy people, so I must build a self-defense weapon for myself, and kill the invading enemy when necessary. The self-defense weapon should not be too good, so as not to be targeted by those who want to."

After a few times of hesitation and thinking, Lu Qi gradually got an idea of ​​what to do.

Just start doing things.

Seeing that Lu Qi was thinking all the time, Li Mu'er thought that he felt it was difficult and was going to retreat, but just as he was about to say something, Lu Qi had already started to light a fire.

"Now my fuel is only charcoal, which burns at a lower temperature than coal. It is impossible to increase the carbon content in pig iron, and it is impossible to make it directly evolve into steel. It is difficult to shorten the production time."

"It is estimated that those senior blacksmiths either found a substitute, or found a unique iron material in this world, or used their own skills to increase firepower, so that they can forge stronger weapons."

"But now I'm only training the strength of my muscles, bones and skin externally. I can't train my breath internally, let alone release my internal energy externally, so I can't increase the firepower. There are no special materials, and there are no substitutes. I have to find another way."

Lu Qi originally wanted to use the steelmaking method to directly cast ironware, so that the hardness of the ironware can directly meet the standard, saving the time and energy of continuous forging.

But now, it's clearly not working.

"It seems that we can only use the method of filling steel." Lu Qi thought for a moment, and planned to use the method of filling steel in his previous life to obtain steel.

The so-called pouring method is not a brilliant technique, but a steelmaking method to obtain high hardness accumulated through the years of experience of countless blacksmiths in previous lives.

It is to pour molten pig iron into wrought iron, increase the carbon content of the molten iron, and reach a certain ratio to obtain steel.

However, this level of steel is still the most elementary.

But compared to cast iron cast iron, the hardness is not a little bit stronger.

Even so, in Lu Qi's opinion, it is enough.

"Okay, let's use the method of pouring steel. In this way, the hardness of the steel will be just as good as that of pig iron, and maybe it only needs a little polishing to get a qualified low-grade knife."

Lu Qi thought about it and started to operate.

The first is to get wrought iron.

There are two ways to get wrought iron.

One is to put iron ore into the steelmaking furnace and directly reduce it to sponge iron at low temperature. This is a relatively early practice in the previous life, and it was rare after the Song Dynasty.

The other is that iron ore is put into a steelmaking furnace and reduced at high temperature to obtain pig iron, which is then decarburized by the steel frying method to obtain "wrought iron".If controlled properly, steel can be tapped directly.

Lu Qi just lacks a high-temperature furnace, so he plans to use the first method directly.

Light the fire, and then put iron ore into it, after two quarters of an hour of calcination, finally get the sponge iron, which is wrought iron.

After that, start a new stove, put iron materials into it, step on the blower with one foot, blow in air, heat up the fire, raise the temperature of the stove, and quickly get molten iron.

Then there is a series of fusion pouring steel.

About a quarter of an hour later, Lu Qi took a look at the color and felt that the molten iron was no longer molten iron, but turned into steel, which was then poured into a standard knife mold and melted into a knife shape.

After cooling for a while, Lu Qi took off the knife mold, picked up the knife with tongs, and hit it with a hammer, showing a smile.

"Haha, it's done."

One-time success, obtained the steel knife.

Lu Qi used the tongs to break it again, and he was sure that the hardness of this steel knife was only [-] to [-]% better than normal low-grade knives, so he was relieved.

"It's not too strong, it's a bit worse than the dagger I hit during the day, but it's definitely qualified. It's enough."

Lu Qi burned the steel knife red, and then simply forged it. This time, he didn't need to hit 360 times, but only hit more than [-] times to smooth out some potholes. Even if it is done.

After that, Lu Qi began to install the handle of the knife, clamped it with wood chips, wrapped it with cloth, and then added some tung oil to polish the pulp, and then the knife was ready.

Just haven't started yet.

Lu Qi was not in a hurry to start, because it took him more than half an hour to build this knife from the beginning of the fire to the completion. If he started sharpening the knife immediately, the neighbors would know when he made the knife.

From the beginning of blacksmithing, Lu Qi had already noticed that the neighbors and neighbors occasionally came out to check, and even a family came to ask.

But they were all persuaded away by Li Muer.

If it is polished at this time, it will definitely be exposed.

Therefore.

Lu Qi put it aside and began to smelt iron materials, forging the weapons he was going to sell tonight, and things for self-defense.

When it's done, let's polish it together.

Sure enough, Lu Qi continued to calcine iron materials to build his own weapons. Even Li Mu'er didn't have any doubts. He only thought that he was still working on Brother Dao's low-grade sword.

"First of all, build the weapon I want to defend myself. This thing should not be too big, but if it is to be killed in one blow, it has enough deterrent power to allow me to get out as soon as possible."

Lu Qi thought of the Three-Length Army Stab, which is very good at bleeding blood, but it has a single function and lacks the chopping function of a sword.

Then it was rejected by him.

"Hey, I thought of it, that's all."

Lu Qi thought of the Nepalese army knives that were recognized in his previous life as being the most ergonomic, commonly known as dogleg knives and khugo knives.
