Chapter 683 Alchemy Room!

Three days later.

At this time, the underground tens of feet below, the appearance has changed greatly.

Wei Hong walked down the passage, the temperature rose as he went down, but he seemed not to notice it, his face was very calm, and soon he came to a black stone door.

He slowly pushed the stone door open and walked in directly.

After entering, the heat wave that was originally coming was directly isolated behind the stone door, and could not cause any impact on the inside, as if the inside and outside of the stone door were two different worlds.

At this time, what appeared in front of Wei Hong was a ten-foot wide underground secret room. The four walls of this secret room, including the floor and ceiling, were all made of a black rock like the door.

This black rock is called basalt.

Basalt has a very special effect, that is, it can completely isolate heat, so this basalt has become an excellent material for major sects to build various alchemy rooms under the ground lung fire vein. Wei Hong prepared some in the fairy city that day, and it just came in handy at this time.

By building this alchemy room with basalt, he doesn't have to worry about being affected by the underground fire.

On the left side of this alchemy room, there are two four-layer stone shelves, and next to the stone shelves is a smooth stone table that is one foot long and three feet high. These things are made by Wei Hong using local materials, and they are very simple.

In the center of the alchemy room, there is an area surrounded by basalt bricks and stones. This area is about one foot square, with eight steps downward on all four sides. Below the steps is a layer of red rock plane, five feet square, with a dragon head connected to the red rock in the middle. The dragon head is about one foot high and is made of basalt. It doesn't look exquisite, but it looks very similar. The dragon head's mouth is open upwards, and there are some complex divine patterns carved around it.

This dragon head is the underground fire mouth he built, and the area where the underground fire mouth is located is the alchemy area.

Wei Hong walked to the alchemy area, reached out and touched the storage room, and a one-foot-high alchemy furnace appeared in his hand. Then he threw it lightly and sent out another spiritual power. The alchemy furnace immediately became more than seven feet high, and landed steadily on the dragon head with a clang. The three legs of the alchemy furnace also landed around the dragon head.

At this moment, this second-level middle-grade dragon-tiger Bagua furnace was completely displayed in front of him.

This is a two-ear three-legged alchemy furnace, the whole body is bronze, and it looks quite simple. The furnace body is divided into two layers, the upper one is small and the lower one is large. Both layers of the furnace body are cylindrical, just like a gourd.

The furnace body is carved with exquisite and complex patterns. The patterns are winding and tortuous, and seem to contain unspeakable mysterious power. There is a winding five-clawed golden dragon in front of the furnace body, and a colorful tiger on the back. The patterns of Bagua and some complicated runes are also carved around the dragon and tiger.

The top of the furnace is a hemispherical lid, and the edge of the lid is also beautifully decorated. Circles of patterns ripple like water waves, which looks very beautiful.

On the front of the furnace, in the center of the five-clawed golden dragon, there is a round furnace door.

The alchemy furnace is now standing on three legs, and each leg is carved into the shape of an animal claw, tightly grasping the ground, appearing extremely stable.

Next to Wei Hong, there is also a stone table, on which there is a white jade array plate, and in the middle of the array plate is a low-grade spiritual stone.

He came here this time just to start practicing alchemy.

"Try it first, find the feeling, and get familiar with the second-level pill formula."

Wei Hong stretched out his hand and flicked it, and more than 20 boxes were placed side by side on the stone table.

At this time, he shot a spiritual power to the white jade array plate on the table, and with a slight pinch of the formula, the dragon head under the alchemy furnace immediately sprayed a thick red flame, tightly wrapping the bottom of the alchemy furnace.

While the furnace was warming up, Wei Hong flicked his hand and opened the lids of all the boxes, revealing the spiritual flowers and herbs inside, as well as some spiritual fruits or rhizome-like materials.

Then he took out more than 20 five-inch-high white jade bottles from the storage bag and placed them in convenient locations.

After the furnace was warmed up, Wei Hong directly picked up a Tianhai flower and threw it in through the round furnace door.

This is the first step in alchemy, refining materials, that is, extracting the essence of these spiritual flowers and herbs and burning all impurities out.

When the Tianhai flower was thrown into the furnace, he immediately controlled the array plate to increase the fire and began to burn it with a high fire so as to burn all the impurities in the Tianhai flower.

Slowly, as the temperature rose sharply, the surface of the Tianhai flower began to turn brown, and the petals curled up, and then slowly burned into gray ash and fell directly to the bottom of the furnace.

Wei Hong kept controlling the fire and observing the situation inside the furnace at any time.

In less than a cup of tea, the Tianhai flower was completely burned, leaving only a pile of thumb-sized blue powder, which was the essence of the Tianhai flower.

Seeing this, he immediately reduced the heat, then stretched out his hand and sent out a spiritual power to gently wrap the small pile of blue powder and took it out. Then he immediately picked up a white jade bottle and controlled the spiritual power to put all the blue powder into the jade bottle.

Pop!

He gently closed the bottle stopper and put it aside without paying attention.

Then Wei Hong picked up another snow jade grass and threw it into the alchemy furnace again to continue refining.

Purple salvia ginseng.

Xingling grass.

Qianjin vine.

Yunlin flower.

One by one, spiritual flowers and herbs were thrown into the alchemy furnace, and then they were continuously refined into essences. Then, Wei Hong took them out and put them into a white jade plate, waiting for subsequent processing.

This time, he tried to refine the Jade Flower Pill.

It took him almost three hours to refine the first step.

After putting the essence of the last spiritual herb into the jade bottle, Wei Hong couldn't help but mutter to himself: "This second-level pill is indeed much more complicated than the first-level pill, and it is much more difficult. If it is not directly promoted to the Great Accomplishment Realm, it may take two or three years of practice to refine the materials in this first step. It is no wonder that alchemy is the most resource-consuming skill among the four arts of cultivation."

After trying to refine the second-level pill, Wei Hong understood more clearly why many cultivators could not choose the skill of alchemy. It was not only because of insufficient talent, but also because alchemy was too expensive. Without strong financial support, it was really difficult to become an alchemist above the second level.

Apart from other things, the consumption of alchemy materials alone is enough to stop most cultivators.

Once a furnace of elixirs is directly wasted, it means that all the materials have been wasted. If you want to continue practicing, you must continue to invest until you have consumed countless materials and truly mastered the alchemy technique.

"Fortunately, I don't need to do this, otherwise I can't bear it no matter how many spirit stones I have!"

Wei Hong sighed in his heart, and then began to continue the next step of alchemy.
