The two of them came to the refining room.

Chu Xinghe handed Su Wanyue a drawing: "Senior Sister Su, you first follow my drawings to build a Xuantie plate." ”

The drawing depicts a five-sided iron plate, with grooves and some scales in the center.

Chu Xinghe saw that she didn't speak, and asked, "What's wrong?" Isn't it easy to build? Why don't I go find another refining master? ”

"Huh? No, no, I'll do it myself. Su Wanyue hurriedly waved her hand, and then explained: "I'm just a little curious, the size of this iron plate is a bit big, and the shape is also very peculiar. ”

Chu Xinghe said with a smile: "This is the Five Elements Rotating Crushing Array, I redesigned it according to the Five Elements Strangulation Array, I don't know if it's useful yet." ”

"Senior brother, you are so powerful, you can actually change the formation by yourself." Su Wanyue exclaimed.

Chu Xinghe slapped her: "Don't be a sycophant, hurry up and work." ”

Su Wanyue understood: "It turns out that the senior brother is from the horse clan!" ”

"You!" Chu Xinghe glared at her angrily, and raised his fan to feint.

Su Wanyue hurriedly covered her head with the drawings, and quickly recognized her mistake: "Senior brother, I was wrong." ”

"Heh~" Chu Xinghe turned the fan in his hand, turned his back to his back, and scolded: "Don't hurry up and work yet." ”

"Oh, got it." Su Wanyue replied in a low voice.

She first measured the size of the black iron plate, then spread a piece of cloth on the ground, took out a pile of mud, and pasted it on the cloth.

Chu Xinghe, who originally took out a rattan chair to sit on it and enjoy it, saw Su Wanyue's movements, and couldn't help but ask curiously: "Hey, little girl, what are you doing?" ”

Su Wanyue said: "I will make a mold first, and then pour the dark iron liquid into it, and the dark iron plate that comes out of this way is uniform in thickness." ”

"Mold?" Chu Xinghe couldn't help but sit up straight and look at her quietly.

At this time, Su Wanyue stopped talking, concentrating on making molds, according to the drawings, carving inverted words and inverted lines on it, and the dark iron plate that came out of this way would be the same as on the drawings.

This process must be done with complete concentration, and there is no room for sloppiness.

After the mold is done, it is dried and baked into a ceramic shape.

Su Wanyue ignited the fire again, preheated the refining furnace, and then poured the dark iron into the furnace to melt it into molten dark iron, and then in the process, she continued to cast magic tricks to remove impurities until there was pure liquid dark iron left.

Then, she added two taels of ant crystals to it and continued to calcinate until the ant crystals were completely melted.

She lifted the lid of the refining furnace again, pinched it with both hands, and used the technique of primers to pull the molten black iron in the furnace out of the furnace and slowly fall into the groove of the mold.

When the groove was filled with dark iron liquid, Su Wanyue couldn't care about the heat, and cast a trick again......

"I'll do it." Chu Xinghe pushed her aside.

He had already understood what Su Wanyue was going to do, he dispatched his spiritual power, and the spiritual power quickly entered the dark iron liquid, compacted it over and over again, and then removed the bubbles.

When there were no more bubbles in the molten black iron, Chu Xinghe used the ice condensation technique to quickly freeze the molten black iron.

The molten black iron is thoroughly cooled and formed.

Chu Xinghe's spiritual power moved, and the Xuantie Disk slowly rose into the air.

Su Wanyue was envious.

In other words, she would never be able to lift such a heavy Xuantie Plate with only spiritual power.

The black iron disc is about the size of two grinding discs, with silver flashes and matrices distributed on it, resembling a labyrinth.

Chu Xinghe put the Xuantie plate aside, and gave Su Wanyue a few more drawings: "Make me a few more Xuantie plates." ”

"Okay." Su Wanyue responded one by one, and according to the drawings he gave, she made the black iron plates one by one.

By then, it was late at night.

Chu Xinghe said: "Senior Sister Su, it's getting late, I'll take the Xuantie plate back for some follow-up processing, and I have to engrave the formation pattern on it, you first build the parts of the other parts, and after you build it, come to my small courtyard to find me." ”

"This is the small courtyard entry and exit card, you can enter at any time."

Chu Xinghe took out a wooden card and handed it to her.

"Okay, Senior Brother Chu." Su Wanyue took the wooden card and nodded.

Back to the courtyard.

According to Chu Xinghe's design, Su Wanyue made modifications again.

After class the next day, I rushed to the refining room to build the rest.

……

The formation of spiritual stones is very complex, and it is a special mineral with spiritual energy formed by mineral fossils that absorb spiritual energy and closely combine with spiritual energy under the immersion of spiritual energy for countless years.

It is also an ore in essence, with a hard texture, which is not broken by a knife, and is not afraid of water and fire.

Usually cultivating with spirit stones is to use exercises to pull and slowly extract the spiritual energy in it, but in this way, the efficiency is very low, and it is only one or two times faster than meditating and cultivating alone.

It's not as good as using pills to cultivate.

I want to extract the aura from the spirit stone.

Su Wanyue wanted to build a large crusher, relying on the bite force of the sawtooth to grind the spirit stone into spirit stone powder, and the spirit stone powder was transported through a conveyor belt into a baking oven.

Heat under the oven, the temperature is not too high, as long as there is one or two hundred degrees, the aura will be separated from the mineral powder.

Pipes and air valves are installed on the oven, and the pressure gauge is installed.

When the pressure is reached, the air valve is opened again, and the aura enters the pipe.

At this time, the aura is with a part of impurities, which needs to go through several filters to filter out the impurities, and the remaining aura enters another compression box through the pipe, and the gas is liquefied by pressurization.

The liquid then flows into the solidification chamber and lowers the temperature further to reach its freezing point, which makes it solid.

The principle is simple, but the operation is difficult.

In the past, there was electricity, machines, and intelligent control...... It is not difficult to manufacture such a set of equipment.

Su Wanyue doesn't know how to make electricity, and she doesn't understand electricity, she can only design and manufacture mechanically.

At that time, she wondered if she could use the formation of the cultivation realm to replace electricity.

After all, it all generates momentum.

Chu Xinghe's own transformation of the Five Elements Rotation Array gave Su Wanyue great confidence.

Five days later.

Su Wanyue packed all the parts with a storage bag and rushed to Chu Xinghe's small courtyard.

Chu Xinghe was not in the front yard.

She made her way to the backyard.

In the carefree pavilion in the backyard, Chu Xinghe was playing chess with Fang Zixuan.

I don't know how Fang Zixuan provoked him.

He kept yelling impatiently, "Why are you so stupid? I said that you shouldn't play here, you want to play here, just your brain, what you don't learn well, you want to learn to play chess, pigs are better than you can play......"

Su Wanyue couldn't help but be a little surprised.

Senior Brother Chu...... There will also be times when you have a short temper and such a poisonous mouth? She remembered that he had always had a good temper, and she didn't reply much when she scolded him, at most she knocked her helplessly.

Su Wanyue hesitated to step forward.

Chu Xinghe suddenly threw the chess piece: "No more." ”

Fang Zixuan said at a loss: "I'm sorry, Xinghe, I'm too stupid." ”

"It's stupid indeed." Chu Xinghe echoed.

Fang Zixuan was a little worried: "I'm so stupid, will Senior Brother Qin's mother like me?" ”

"Definitely not." Chu Xinghe said casually.

Fang Zixuan's face became even more ugly, and she was about to cry when she saw it.

Su Wanyue frowned, didn't hide anymore, came out from behind the pillar, and raised her voice and said, "Senior Sister Fang, don't listen to his nonsense. ”
