It was the middle of winter, the weather was cold and frozen, and more than 200 miles on the north bank of the Jingjiang River, there was a nameless extinct volcano with snow on the tip of the mountain. At the foot of the volcano, there are seven steaming hot spring pools, among which the hottest is the strongest, and the sulfur smell is the largest, a naked man, with skin as red as a lobster, and long hair scattered, is sitting cross-legged, holding a folding fan, constantly blessing him with wind and thunder spells.

The man with his hair soaked in the hot spring pool was none other than Bai Fu, and it was now his third day in the extinct volcano. After a few days, the original soup pool was no longer effective for him, so he changed to this pool that was the hottest (nearly sixty degrees), obviously closer to the earth-fire magma, and carried more and more essence of realgar, and in order to make himself last longer, in order to distract himself, he also sacrificed treasures.

"East from Mount Tai Thunder ......" a five thunder mantra blessed the wind and thunder fan, Bai Fu was weak for a while, and wanted to continue to persevere, but he didn't even have the strength to pick up the wind and thunder fan, and the wind and thunder fan fell into the soup pool.

The weak hand grabbed two handfuls in the soup pool, but did not catch anything, and consumed a lot of physical strength, Bai Fu's body shook, his body fell backwards, and he lay on his back in the water.

"Persistence, it's not yet to the point where you can't hold on and want to faint!" "The whole body is like thousands of ants gnawing, itchy and painful, no different from a thousand cuts, but Bai Fu decided to persist and reach his limit before coming out of the water.

Bai Fu's body floated and sank in the water, and it could be seen that in addition to his face, his body was full of red blisters, and in some places, scales appeared.

After staying in the water for another quarter of an hour, when black and white scales appeared all over his body, Bai Fu, who was already full of Venus, crawled out of the soup pool with his hands and feet, and lay on the ground, like a dead snake.

It took a quarter of an hour for the hideous scales on Bai Fu's body to dissipate, but his skin was still red and covered with blisters.

"Shhhh

After getting dressed, the wind and thunder fan sunk in the pool was withdrawn, Bai Fu sat down on the stone next to the pool, silently transported the primordial spirit, and breathed.

After breathing for a long time, he went to the mountains to find a hare with a full stomach, and after finishing his mind, Bai Fu untied his clothes and pants, and jumped into the soup pool with a male goldfish jade pendant.

..................

Another three days passed, Bai Fu had no feeling for the realgar contained in the hot spring pool, and after soaking comfortably for half an hour, he dressed neatly, fed the Qingluan and the red dragon centipede, and slowly shook towards the top of the mountain.

When he reached the top of the volcano covered with snow, Bai Fu saw a large circular crater that grew bigger and bigger as he went down, and the ground was so white that he couldn't see it clearly.

"This volcano has been dormant for more than a thousand years!" Bai Fu pulled off the snow on the ground, revealing the hard and dense volcanic rock, and knocked it like a professional, and then talked nonsense.

It didn't matter how long the volcano had been dormant, so he pretended to know very well and studied it, Bai Fu searched carefully around the crater, and saw a lot of male yellow and orpiment, but they were all mixed powder, and the quality was not very good.

"Let's take a look!" Bai Fu, who didn't see the high-quality sulfur, jumped into the crater with a move in his heart.

......As soon as Bai Fu landed, the gravel and fine sand slid towards the bottom, and after feeling the terrain conditions, he moved, performed a light body technique, and swept down like wings.

Several vertical jumps, swept down for a hundred meters, Bai Fu reached the bottom of the crater, very hot, big winter, Bai Fu felt like summer in seconds.

All around was the white mist after the snow had been vaporized, filled with a thick smell of sulfur, Bai Fu held his breath and calmed down, and his eyes searched for it. It took half an hour to carefully explore the bottom of the crater, but in the rock layer after the volcanic ash solidified, I found a lot of stones mixed with realgar, orpiment, and cinnabar, that is, cinnabar. These realgar ingredients are good, the fist is big, at least condensed near the crater for more than ten years, some of the big ones, even twenty or thirty years, and he even found a child with a big head, estimated to be fifty years old.

"The fifty years of realgar are good, collect them first, and use the transitional products before the hundred years of realgar. Bai Fu thought about it, walked to the place where he found the fifty-year-old male yellow, grabbed it with his hand, and the Blue Blood Fire Sword appeared in his hand, digging down two meters, and digging out a stone the size of a child, mixed with black, yellow and red.

This stone, the black is volcanic ash, which will be blown away, the red is cinnabar, and the yellow is the realgar that Bai Fu is looking for and the orpiment that he does not want.

Whether it is realgar, orpiment, or cinnabar, they are all soft things, mostly powdery, rarely granular, but this mass of male orpiment and cinnabar aggregates are different. It has been under a two-meter-thick rock layer for 50 years, and is not only oppressed by rocks, but also baked at low temperatures, but it has formed solid crystals, no harder than rocks.

Realgar is heated at a low temperature in the air, it will oxidize into arsenic, the temperature of this crater is very hot, although I don't know whether it is the temperature of arsenic, but I am afraid that this realgar oxidizes into arsenic Baifu, and quickly included it in the Qibao gourd.

"Luckily, a 50-year-old realgar was found in this crater, and maybe you don't have to go too far into the volcano to find a 100-year-old realgar. Bai Fu thought about it, jumped into the air a hundred feet high, and after taking a breath, he fell towards the hole with a sword under his head and feet.

Bai Fu fell freely, his speed getting faster and faster, and on the Blue Blood Fire Blade Sword, there was a crimson sword more than a zhang long, cutting through the air and emitting a piercing roar. The air flow was flowing rapidly, enveloping Bai Fu into it like a gang qi shield, making his figure look a little blurry.

Bai Fu fell faster and faster, and finally the Gang Qi released by the Blue Blood Fire Blade Sword rubbed violently against the air, and the already scorching Sword Gang sparks splashed.

"Boom!" There was a loud bang, and Bai Fu fell into the hole in an upside-down posture, dusty and like smoke.

When the dust settled, a funnel-shaped pit appeared in place, and at the bottom of the pit was a dark and bottomless hole, but Bai Fu was gone, thinking that he had entered the hole.

Bai Fu did enter the cave, and rushed down nearly twenty meters before he stabilized his body. It was dim, sweltering, and there was a blind, pungent smoke that was better than he was able to breathe and his eyes were covered with a layer of gas.

Bai Fu looked down and saw a dark red light that was a little bigger, and knew that it was underground magma, and his current cultivation was a death.

After calming down for a while and adapting to the darkness, Bai Fu turned on his night vision ability, and without wasting time, his divine thoughts were emanated, and he went deep into the mountains and rocks, and quickly searched for them on the surrounding mountain walls.
