People in gray robes were walking here busy, transporting items or handing over affairs, and there were tinkling sounds of tinkling and tinkling everywhere, and there were busy scenes everywhere.

Chen Luo has never been to this kind of treasure-refining workshop in the future, and he can't help but be curious. He kept looking around while walking.

Maybe Ma Xiuxiu had already said hello in advance, and the people from the refining workshop did not stop Chen Luo and the man in the gray robe, and let the two of them walk in.

The two turned left and right inside, and soon arrived at a courtyard where a large black room was located, with no windows and only a gray-black stone door, which was protected and even confidential.

The walls of the room were made of a kind of black stone, and there was no gap. They looked like a whole piece of big stone was hollowed out and carved.

"Young Master Chen, when you arrive, this house is the weapon refining room." said the gray-robed man.

"What kind of stone is this? It looks very special." Shen Xiao touched the wall, and the tentacles were extremely cold and smooth, as if they were silk satin, and they couldn't help asking.

"This is a black cold stone, which is extremely strong and has heat insulation. It was mined and transported by the senior masters of this cabinet from the extreme north. If the weapon refining room is built with ordinary materials, it will be damaged in a few years because it cannot withstand the scorching temperature." The man in gray robe explained, while taking out a silver talisman and pressing it on the stone door of the weapon refining room.

A white light immediately appeared on the surface of the talisman and melted into it.

A layer of white light appeared on the stone door, but it quickly dissipated and the door slowly opened.

"Please, Mr. Chen." The man in gray robe brought Chen Luo into it.

The black room has a large space, only a dozen meters in radius. A large casting stove is located on one side of the room, and some unextinguished fiery red charcoal blocks are piled at the bottom of the stove.

Near the casting furnace is placed a large basket with special carbon stones with a slightly reddish sized fists.

On the wall next to it, two small gourd-shaped jars were hung, and I don’t know what was inside.

In addition to the casting furnace, there is also a large casting table, hammer, pliers and other tools on the other side of the room.

"Mr. Chen is not proficient in refining weapons. Please explain how to use the things here." Chen Luo glanced left and right, and soon saw the situation in the house and said to the man in gray robe.

"Yes. These are red carbon made of special materials, and the flame temperature formed after combustion is much higher than that of ordinary flames." The man in gray robe said, pointing to the red carbon stone in the basket.

Chen Luo picked up a piece of carbon stone and looked at it twice, and soon put it back.

"These small jars contain fire-nitrifying powder, which can further increase the temperature of the fire. The combined red carbon and fire-nitrifying powder can melt most of the spiritual materials. Of course, it is still incomparable to spiritual fire." The man in gray robe took off a small jar on the wall, which contained dark red powder like sand.

Chen Luo heard this and felt secretly happy.

To melt the materials of Pure Yang Sword Embryo, it does not require too high temperature. The flame of the casting furnace in front of you is enough.

The man in gray robe then explained how to adjust the flame temperature of the casting furnace and how to use various utensils on the casting table.

Remember Shen Luo in your heart.

"Young Master, do you need other things?" asked the man in gray robe again.

"No, these are enough. Next, I will stay here for a long time and don't let others come in and disturb me." Chen Luo said.

"Don't worry, Mr. Chen, I will continue to give orders. I will never let anyone disturb you." The man in gray robe said immediately.

Then, when the man saw Chen Luo, he didn't say anything to him, so he said goodbye and left with tactfulness, and closed the stone door.

After closing the door, the light outside was completely isolated. Fortunately, a piece of glowing fluorite was installed on the top of the house, which was enough to illuminate the environment here.

Shen Luo cleaned the ground of the room, cleaned up a flat open space, took out various materials for laying magic arrays, burned array patterns on the ground, and arranged a magic array.

This magic array is recorded in the Pure Yang Sword Book and is used to assist in sword refining.

He didn't know much about magic circles, and when he was in Changshou Village in his dream, he arranged a magic circle in order to take the people from Changshou Village away.

The sword-refining array in front of me is quite complicated, and Chen Luo's current cultivation level is low, far from being as good as the Dream Longevity Village, so it took three days to complete the arrangement.

According to the Chunyang Sword Technique, he inserted more than 20 pieces of immortal jade into the magic array, carefully checked and confirmed that it was correct, and then made a little trick.

The magic circle immediately emitted a red light, making a howling sound like a roar of a strong wind, and the whole room trembled slightly.

He looked happy and hurriedly made gestures to stop the magic circle.

Arrange the magic array, sink to the casting platform, waved out the many materials for refining the Pure Yang Sword Embryo and put them on it.

Instead of igniting the stove immediately, he first processed various materials, some cut into small pieces, and some ground into powder.

After working hard for half a day, I finally got the materials all one by one.

After completing the preparations, he took a moment to regulate his breathing, restored his energy and spirit to his peak, and truly began to refine the Pure Yang Sword Embryo.

He first lit the forging stove, took out a golden three-legged cauldron, and placed it on the fire.

This is a simple weapon refining furnace, which is usually something that only novices can use. It is impossible to refine weapons when sinking, so using this triangle cauldron is enough.

As the flames swept, the triangular cauldron quickly turned into a dark red color, emitting a scorching high temperature.

He flipped his hand and took a large jade bottle, poured the silver-white liquid contained in it into the cauldron, and then took a piece of fire-red spiritual wood, which was the main material for refining the pure Yang sword embryo, and threw it into the triangular cauldron, and activated the fire to calcinate.

These silver-white liquids are called Lingshi, which are a spiritual liquid that can refine impurities in wood-based spiritual materials.

Three or four hours passed in a blink of an eye. As the temperature in the triangular cauldron became higher and higher, most of the quenching dew inside was evaporated, and the residual liquid became viscous. Drops of fiery red mucus liquid appeared on the surface of the Huolin wood, and signs of melting began to appear.

Chen Luo saw this scene and took the tinea powder hanging on the wall and threw it into the fire. The fire suddenly became more and more vigorous and continued to calcinate.

Two more hours later, the firewood finally melted completely, mixed in the spirit-tempering dew, and turned into a pure fire-red mucus.

The impurities in the Fire Lin Wood have also been completely refined.

Shen Luo waved his right hand and a magic power shot out, wrapping the liquid in the cauldron.

He pointed at the tip and the fiery red liquid flew out of the triangular cauldron and landed in a piece of blue jade two feet long on the casting platform.

There is a sword-shaped groove on the green jade, and the fiery red liquid falls into it, spreading rapidly, quickly filling the sword-shaped groove.
