You won’t be afraid if you learn mathematics, physics and chemistry well and cultivate immortality

As soon as the secret door in the corner opened, Master Lu stood up and walked in. Tie Zhu followed him in. Only the little rookie remained in place in a daze.

Master Lu couldn't bear it any longer and started to spray: "You brat, why are you standing there stupidly? Come on, catch up, all this spiritual energy has escaped."

"Oh, come, come, come." The sprayed small vegetable chicken quickly followed, and then heard there was a noise in the back, oh, the door closed slowly again.

Only then did he look inside. The place he was standing on was a platform and then it went all the way down. There were countless spiral staircases. He was worthy of being a weapon refiner. This design is really good.

After looking around, I walked down and realized that the spiritual energy here was much richer than outside. After taking this breath, you can clearly feel that the spirit energy circulates in the muscles and veins in the body several times faster. It is conservatively estimated that it is five to six times higher than the outside world.

Tie Zhu looked at Junior Brother Ma who was obviously surprised. There was a smile on his lips. What did he mean?

Hey, I continued walking down for about a cup of tea. Finally, it was tea time. I found a stone room covering an area of ​​about an acre. There were many brocade boxes of different sizes placed in rows of small grids on the wall. No need to guess. Good stuff.

The table in the middle looks very familiar. Oh, isn’t it the integrated stove in the kitchens of later generations? It's just that items such as pots, knives, and chopping boards are replaced with hammers, pliers, files, etc. This design, this similarity. The sink, oh, no, that one is a furnace for firing and smelting, and it can be considered a furnace.

Because as the eldest disciple, Tie Zhu had already piled charcoal into the basin, but the charcoal looked better than the ones made outside, as it was dark and shiny. I soon discovered that something was different. I lit the charcoal and pulled the cowhide box next to it to make the fire strong. The temperature of the flames turned out to be golden white, and the temperature in the basement felt like it was rising.

Seeing that the iron pillar was on fire, he went to open a vent, and a cool breeze blew in. The heat was not so hot in an instant, so he stood next to the little rookie and prepared to watch the master refining the weapon.

The class representative said: The color of the flame corresponds to the relative temperature, that is, the color temperature. Generally speaking, the lower the temperature, the less short-wavelength light and the more long-wavelength light. The color is reddish or yellow, and conversely blue or white.

The flame color and temperature of smelting fuel correspond to:

Dark red: around 600 degrees Celsius.

Deep red: around 700 degrees Celsius.

Orange-red: around 1000 degrees Celsius.

Pure orange: around 1100 degrees Celsius.

Golden orange: around 1200 degrees Celsius.

Golden yellow: around 1300 degrees Celsius.

Golden white: about 1400 degrees Celsius.

Pure white: around 1500 degrees Celsius.

White and blue: above 1500 degrees Celsius.

Sky blue: around 2000 degrees Celsius. Generally, smelting cannot reach this level and other materials need to be added to support combustion. There are also blue, purple, and black.

Note that this is only a judgment of fire color during smelting and cannot be used in other places. Fire is also divided into flame core, inner flame and outer flame. The flame temperature increases from the inside to the outside.

"How's it going? Isn't this popular enough?" Tie Zhu was bored and muttered to Musk in a low voice.

"Well, this fire is really good." The little novice praised sincerely.

"No, it's all spiritual charcoal." Tie Zhu responded in a low voice.

"Spiritual charcoal?" The rookie asked in surprise. Any item with the word "spiritual" on it is no small matter.

"This can still trick you. Well, it's all in that big wooden box over there." Tie Zhu raised his hand and pointed to a big box in the corner.

"There are so many?" The little rookie was speechless. When have you bought spiritual charcoal in boxes? What kind of family is this? After all, this is not cheap. I remember asking there, and a spiritual wood plaque cost several hundred taels of silver.

"Haha, these things are not worth much. I made them all by myself." Tie Zhu said nonchalantly.

"Did you make this spiritual charcoal yourself?" The rookie was surprised.

"Well, when I was six years old, I followed my master into the mountains to burn charcoal. It's very simple." Tie Zhu replied proudly.

"Is this really that simple?" The little rookie retorted speechlessly upon hearing this.

"It's not bad. I don't know how big this vast ridge is. Be careful and go deeper. As long as you find a low-level spiritual vein, you will be half successful. Then drive away the monsters entrenched above, cut down those trees that are more than a hundred years old, and take advantage of them. Forty circles in the heart of the tree are suitable for burning into spiritual charcoal, which can be used for refining weapons here. The outermost sixty circles and tree trunks are burned into ordinary charcoal, which can be used for blacksmithing outside. This is also the ratio of the weapons we forge here. One of the reasons why other places are better." Tie Zhu said a lot of things proudly.

Isn’t it okay to hear a little green chicken? If you use spirit wood to burn charcoal to make weapons, the smelting temperature will be obviously higher, the iron impurities will be less, and the quality will inevitably be higher.

"Okay, okay, you two are muttering somewhere, watch, I will show you how to refine this bearing." Master Lu interrupted when he saw that the iron ingots in the furnace had completely melted into molten iron. Dumb gossip.

"Aaaaah. Got it." The two idiots hurriedly stopped chatting and responded.

Then he watched Master Lu attentively as he began to refine the weapon. As expected of a master of weapon refinement, he pinched out a ball of orange molten iron and flew out of the furnace. Landing on the forging platform, he transformed into a small circle.

Seeing that the red color of the iron ring was beginning to fade, I picked up a hammer and a round iron, put the round iron around the iron ring and started beating. Soon an oblate inner ring of the shaft appeared.

Then it was soaked in water, and the sound of "bah bah bah" disappeared after a while. Then pick it up and look around, then pick it up with the file and pull it gently. Then it's completely fine.

This is simply a roundabout way.

The little rookie was thinking to himself that he was indeed a well-known weapon master in the world of cultivating immortals. The handmade ones looked better than those produced by mechanization in later generations.

Then there are the stick pillars. I saw Master Lu take out a hair-like thin wire, measure the diameter of the outer wall of the inner ring of the bearing, and then fold the thin wire in half a few times to get a size.

It's the same old trick to pinch out the molten iron from the stall. When the red color starts to fade, I change the hammer to a small pliers and start pounding.

Finally it was thrown into the water and soaked in water, then another one. It took more than thirty before I stopped. Twenty-seven iron pillars were selected and cut with a small saw to the same width as the inner ring.

Tie Zhu said, are you calling me? Unfortunately I have no evidence.

Finally, I used a file to slowly grind it to make it round and completely turn it into a cylinder. In the last twenty-seven, two slightly smaller ones were re-sawed and ground to replace the other two.

Finally, twenty-seven cylinders with almost the same length and size were obtained.

This made the rookie watching on the sidelines scream in his heart.

The outer ring is even simpler. Pick up the inner ring, place a cylinder on the left and right, and pull a thin wire against it to get the size. Next is the process of making the inner ring. Soon the first bearing in the world of immortality was built by hand.

Everything is ready, just assembly required.

This installation was so smooth because Master Lu added some pine oil. After the assembly is successful, I took the outer ring in my hand and found that it was round and round without stopping.

Xiaocaiji also proposed to add a trap between the inner ring and the outer ring on both sides of the bearing to prevent the shaft column from wandering off for a long time and falling out. This is simple and quick. Of course, in order to reduce friction, the two ends of the shaft column should be rounded. Things were corrected incidentally.

Finally, a bearing comparable to mechanized manufacturing was successfully produced. While Master Lu was recording the data, the novice picked it up and played with it. Well, this is the feeling, exactly. I can only sigh with emotion, he is worthy of being a master of weapon refining.

In the end, Master Lu grabbed the bearing from Tiezhu and said to him: It's your turn to build it. So I carefully played with this bearing that I had spent a lot of time on.

What else can I do? I can only continue to refine it myself. But nothing went wrong. After all, the detailed data has come out, so just follow the example. Finally, two almost identical bearings appeared in the refining room.

The little rookie can see it clearly and doesn't bother the two masters about anything. So he asked Master Lu for help in building a still for distilling liquor. When Master Lu heard this, he immediately got excited and dropped the bearing. So he took Xiaojiji to draw the drawings. Xiaojiji said that it would not be too late to try the bearings first and then draw the drawings later.

It's not easy to arrange. "Tie Zhu, go and replace this bearing on the carriage." Master Lu directly ordered his eldest apprentice to do hard work.

Come on, the novice can only just draw the drawings.

So the three of them went up to do their own business. Tie Zhu worked hard to change the bearing, but he was also curious about how much energy he could save by replacing the bearing. After all, he was also a weapon refiner. Although he is now an unknown person, He cannot kill his dream, which is to become a slightly famous weapon refiner.

Because he still doesn't know that his idol master was hunted for tens of thousands of miles and was finally forced to live in seclusion here, otherwise he wouldn't have this dream.

The rookie was still holding charcoal in his hand to draw the drawing, while Master Lu was staring at the drawing and asking questions while looking at it. The rookie can only explain while drawing.

After the final sketch was finished, I needed to use wood to steam the wine.

I was almost shocked, who am I? A well-known weapon-refining master in the world of immortality, whatever wood he wants, and even if wine vapor leaks out, he uses metal materials to make it, so he is not afraid of rust. Just make it from meteorite iron. As a weapon refiner master, what you lack most is, of course, rare weapon refinement materials. What is lacking most? Of course it's weapon refining materials.

Meteoric iron is not a rare thing, so a low-grade magic weapon-level wine was steamed out.

The cooling pot is forged by adding some thousand-year-old ice crystals, which makes the pot cold and not hot no matter how it is heated. As expected of the master of weapon refinement, most people can't think of this brain circuit.

The manufacturing speed of this wine steamer is more than twice as fast as that of bearings. After all, this does not require great care. Soon Master Lu brought in a large vat of ordinary wine and began to steam the wine.

The bearings of the iron-column carriage have not yet been replaced, but pots have been set up in the basement to steam wine. No matter how you describe the aroma of the wine in a relatively confined space, it's intoxicating when you take a sip, look at the little rookie's rosy little face.

"Cough cough cough" Actually, is there any possibility that it is lack of oxygen?

It is impossible for a cultivator to die of suffocation due to lack of oxygen. Spiritual energy is also Qi. What's more, this basement is built on low-level spiritual veins, so it is even less likely to suffocate to death. It's just that lack of oxygen is a symptom of the body.

Master Lu impatiently took half the cup and drank it all in one gulp, his eyes shining brightly as soon as he opened them.

"Master Lu, this wine will become richer and more fragrant the more times it is steamed." The little novice quickly persuaded Master Lu to keep drinking.

"Hahaha, okay, okay." Master Lu happily agreed.

So the two of them watched the distilled wine slowly dripping into the wine jar. Master Lu looked at it for a long time, but he was bored anyway, so he stroked his stubble and began to suffer from occupational diseases.

Watching from the side, he underestimated in a low voice: "What would happen if a spirit gathering array is added to this wine steaming method? Hey! It's a pity that I don't know how to draw a spirit gathering array. Otherwise, I might not be able to make a spirit wine using this wine steaming method. .”

The rookie who was standing aside and forced to do business suddenly had an idea flash in his mind, so he hurriedly took out his treasure and took out the small purse containing more than a dozen broken spiritual stones from his inner pocket.

The little foot is chopped, and the heart is lifted. Gritting his teeth, he took out one and handed it to Master Lu.

"What are you doing for me with the Broken Spirit Stone?" Master Lu looked at the rookie and asked in confusion.

"Master Lu is like this. Let's see if this can be ground into powder, sprinkled in and steamed together. Under high temperature, the spiritual energy may be released and fused with the wine. In this way, the spiritual wine will be successful." Xiao Jiaoji explained.

"Hahaha, yes, yes, this will definitely work." Master Lu's happy, excited and joyful mood was directly expressed as a smile on his face.

After saying that, he was about to crush the broken spirit stone and throw it in, but the rookie hurriedly stopped him.

"Master Lu, wait for a while, and then crush it and sprinkle it in when it is steamed for the second time."

"Okay, okay, okay." Master Lu readily agreed.

Then there is waiting. Waiting is the longest thing, boring and boring. Master Lu was in a good mood and finally spoke. "Boy Ma, why don't you accept me as your teacher? How about I teach you everything I have learned in my life?"

"Ah, this, this." The little rookie was shocked by this sudden topic.

"It's okay. You don't have to agree to me right now. You can think about it carefully. To be honest, I'm very optimistic about you. You are also smart and have a good brain. You have good talent in weapon refining. Follow me and learn for ten or eight years. He must also be a great weapon-refining master." Master Lu said sincerely.

"Ah, this, Senior Lu, please allow me to think about it carefully. After all, I just came back from the Luoxia Sect." The rookie could only vaguely agree.

"Well, it's okay. Becoming your teacher does not conflict with your status as a disciple of the Luoxia Sect. Anyway, you should consider it slowly and don't rush to answer me. My door here will always be open for you." Master Lu solemnly made a promise .

"Well! Thank you for your love, senior." The rookie also thanked her sincerely.

In order not to make the atmosphere too awkward, the rookie drank some distilled wine to taste.

Well, the wine smell is already relatively weak, so it’s time to evaporate it a second time.
