Thorn, stab, stab!

Several flames reverberated in the cave, and the pale cyan inner wall of the cave began to burn, covered with a layer of red flames.

After a short time, about a dozen breaths, the flames disappeared, and an arched white pattern appeared on the inner wall, as if the bluestone had been burned to lime gray.

"What is this?"

Long Zun walked over and pressed it with his hand, the white arch seemed to be a door, only to hear two clicks, the door opened, revealing another stone cave behind the inner wall.

"This ...... It's actually a suite. ”

Long Zun's eyes widened incomparably, it was obvious that the cave was connected to the stone cave behind, and there was only a stone wall in the middle, and the fire alchemy technique was the key to open the two connected gates.

Step inside, step into the back of the inner wall, as if through an invisible barrier, a wave of heat rushed in.

"Hey, it's still warm in winter and cool in summer, go to the inside in the winter, and stay outside in the summer. Long Zun laughed to himself.

In front of him is also a cave that is no less than the outside, more precisely, the two are connected together to form a complete cave.

The place where he stayed before was only a part of the cave mansion, Yao Feng's personal disciples, and he didn't prepare an alchemy furnace, is that still the cave mansion of Yao Feng's personal disciples?

The heat wave inside the room is surging, at least more than ten degrees hotter than the one outside, and the inside and outside are simply two different seasons.

Walking further inside, bypassing the obstruction of a stone wall, the vision suddenly widened, and I was able to see everything in the room, including the furnishings inside.

In fact, there is nothing to furnish, just one more alchemy furnace, which occupies nearly one-third of the position.

Under the alchemy furnace, there was obviously a round bronze stone slab of the same color as bronze, and there was a hole in the middle, and there was a flame in it, and the heat wave in the middle should be produced by these flames.

"This ...... It should be the earth fire! I've only heard that Yao Feng has the Earth Fire Alchemy, and this is the first time I've seen it. Long Zun stared at the red flames and whispered.

The alchemy furnace is there, the medicinal materials are also prepared, the earth fire is also there, and the things needed for alchemy are almost all ready.

Therefore, Long Zun couldn't help but start alchemy, you know, this is his first alchemy, he is inevitably curious, and he seems a little impatient.

Reaching out and grabbing one of the handrails of the alchemy furnace, he raised his hand and shook it, and the alchemy furnace weighing two or three hundred catties directly threw him on top of the earth fire, causing the earth fire to scorch the bottom of the alchemy furnace.

"Blazing fire, burn your ass, heat the pot before alchemy. Long Zun said to himself, completely treating alchemy as a stir-fry.

The earth fire was full of firepower, even if no one controlled it, the alchemy furnace began to heat up after a while, and there was obviously white gas wafting out from the bottom of the alchemy furnace.

"The pot is hot, and you have to put medicine. As he spoke, he took out a whole portion of the medicinal materials of Bigu Dan, picked out one of them, and threw it into the alchemy furnace.

After a while, the medicinal herbs thrown into the alchemy furnace turned into liquid and rolled inside.

Long Zun grabbed another elixir and threw it into the alchemy furnace, but this time the alchemy furnace did not refine this elixir, and it took a long time to melt a little.

"This is, you want me to add fire!" As he spoke, he recited the mantra the most, his hands kept moving, and one after another fire control techniques were played, and the ground fire under the alchemy furnace suddenly became intense.

The surrounding temperature became significantly higher, and the melting speed of the elixir in the alchemy furnace began to accelerate.

Wait until a whole elixir turns into a liquid, and the liquid that supports the original existence in the alchemy furnace mixes together, intertwines, and finally turns into a pale cyan stream of water, flowing at the bottom of the alchemy furnace.

"Haha! I'm a genius. Long Zun laughed twice and boasted.

Alchemy is a mixture of various medicinal materials, and it can be regarded as success to refine the pill you want to refine, but the first and most important step is the fusion of the medicinal liquid.

Among the ten parts of Bigu Dan medicinal materials, there are five kinds of medicinal materials in one of them.

The liquid refined from the two medicinal materials has been fused, as long as the remaining three medicinal materials are put into the alchemy furnace at one time, so that these medicinal materials can be fused, you can do the final step to condense the elixir.

If you want to alchemy, you must first master fire alchemy in order to control the earth fire, so as not to fail in alchemy.

Of course, if you are a fire attribute and practice fire-based exercises, you can rely on your own flame alchemy, but the Dan recipe is different, and the Dan Fire required is also different.

Therefore, most alchemists choose to use fire to refine, unless it is that kind of power, and their own Xuan power cultivation is sufficient to support the refining of pills.

While using fire alchemy to control the earth fire, Long Zun slowly added the remaining medicinal materials of Bigu Dan to the alchemy furnace.

Soon, the remaining three medicinal materials were all put into the alchemy furnace by him in turn, and the five medicinal materials were completely fused together.

Next, only the step of Ning Dan remains.

Ning Dan is the most important thing in alchemy, Ning Dan fails, all the medicinal materials in the Dan furnace are in vain, and the most you get in the end is a pot of useless residues.

Only this step is missing, the first furnace of Bigu Dan is about to succeed, Long Zun's expression is solemn, it takes a long time, he doesn't want to make a failure in the end.

"Knot!"

The mouth spit lightly, the movements of the hands were as smooth as flowing clouds, and one by one the hands were duel on the Dan furnace, controlling the temperature of the Dan furnace and the scorching degree of the earth fire.

This step is the most consuming Xuan power, that is, his Xuan Power cultivation has reached the peak of the martial artist realm, otherwise just one knot pill can suck him dry.

Most of the Xuan power in the body was used up, and the pill finally began to condense slowly in the Dan furnace, and a faint fragrance wafted out of the Dan furnace, and a sip of it could relieve some of the hunger.

"It's done. Long Zun felt the formation of the Bigu Dan in the Dan Furnace, removed the earth fire, and reached out to open the lid of the Alchemy Furnace.

A black pill the size of a thumbtip flew out of the Dan furnace, and Long Zun hurriedly reached over and grabbed it in his hand.

"This is Bigu Dan, how is it different from what I used to eat!" Long Zun frowned slightly, looking at the Bigu Dan in his hand.

The black root was very different from the kind of Bigu Dan with a cyan halo he had eaten, and the Bigu Dan he had eaten was all round, like nature, with a round and smooth surface.

But the condensation pill he just refined in his hand is different in color, and the surface is pitted, as if he has suffered a disaster, and his face is numb.

If it weren't for the medicinal fragrance emitted was the same as the Bigu Pill he had eaten in the past, he almost thought that he had refined a strange pill.

However, even if it is not a strange pill, it is also a defective product, congenital defects, this thing, he doesn't dare to eat it, and the provincial master dies before he can get started, and he becomes a guinea pig who tries medicine.

Burst!

At this time, the black Bigu Pill in his hand made a sound like a fart, and then the pill dried up, and finally only a black paste remained.
