When the two of them walked to the top of the slope, they saw two peaks in front of them, and the spring of the hot spring was between the two peaks. The big mountain peak is towering into the sky, and the small one is more than ten zhang high, but it is strange that there is not a single grass or tree on this small peak, but a bare big stone stands there.

Tianci stepped forward, came to the bottom of this stone peak, felt a hot breath rushing to his face, touched it with his hand, this stone wall turned out to be very hot, thinking, there is a fire in this underground, no wonder there will be hot springs gushing out here.

The Taoist priest led him to the side of the stone peak, and saw a row of stone steps carved out of the stone wall, and went up along the stone steps, and at a height of five or six zhang above the ground, there was a hole the size of a pot lid.

"This is the Dan furnace opened up by the ancestor back then. The Taoist priest pointed to the mountain peak and said.

"When my master encountered an accident, he told me about it when he was dying, and told me that I must take good care of this furnace, saying that it would take another sixteen years to complete the great work and achieve one of the great feats of this sect. For the past 16 years, I have been guarding this mountain, collecting rare herbs and beast bones day and night, and smelting them in this furnace in spring and autumn. ”

"Are you saying that this entire mountain peak is actually an alchemy furnace?" asked Tianci.

"Yes, I heard the master say that the ancestor found that there was a fire here, which lasted for many years, and the belly of this mountain peak was hollow, and it happened to be divided into three rooms, including Danding (reaction room) and Huachi (sublimation room) and condensation room (distillation room), which was a natural alchemy furnace, which was just used for the refining of the unique qi pill that was passed down from this sect. ”

God-given is because I have heard the master talk about it. This Qi Dan belongs to the Inner Dan Technique, which is an important cultivation method of Taoism, and is a kind of Taoist Qi Alchemy (Qigong), which uses the cultivation of internal strength to sublimate and improve the limit of the human body or achieve the purpose of immortality.

Practicing this technique, they are all masters of advanced Taoism, taking the human body as the Dan furnace, refining the "five qi in the chest", and finally reaching an extremely high level of internal cultivation, so it is called "Inner Dan". Many Taoist immortals have extremely high attainments in this area, but due to the limited life of people, even if they are Taoists who have reached the age of ancient rarity, the time spent on cultivation in their lives is only about thirty or forty years.

The alchemy patriarch mentioned by Daoist Buji actually thought of using the naturally formed warm fire pill furnace here that is similar to the human body to carry out internal and external refining, and it is not limited by human life, old age, sickness and death, and can be passed down from generation to generation, extending the limit time of cultivating inner pill by several times. This idea is really exquisite, and it will cultivate what a profound internal power Qi Pill it contains.

"The ancestor carved a hole in the lower part of this stone peak, and according to the secret recipe of this door, his lower chamber was filled with three immortal pills, yellow pills, red stone grease, dansha, realgar, haloxian, alum stone, calamine, pengsha, mercury frost, mica and other alchemy stones, and then sealed the hole. In the middle room, another hole was opened, and rare medicinal materials such as fairy grass and tiger bones were put into it in spring and autumn every year. The priest pointed to the hole in the stone peak and said.

Buji led the heavens to the back of the stone peak, only to see that at the foot of the stone peak, a small hole was chiseled, and inside the hole was a stone nest, in which some black liquid was gathered, glowing with some oil.

"The golden stone medicinal materials in the stone peak, fumigated by the internal fire, sublimated gas, in the upper room of the stone peak, gathered and condensed into drops, and then infiltrated and infiltrated by the stone body on the yin side of the stone peak, and finally gathered into a pill paste in this stone nest. ”

Buji said with tears in his eyes: "I don't think about it, this year has reached the time of the hundred years of the refining of the Qi Pill that Master said, and after I uncovered the place marked the place where the Pill was taken according to the method explained by the Master, I found that there was only a handful of black water, and there was no Pill Pill." Could it be that I made a mistake and broke it down?"

After listening to him, Tianci approached the cave and took a closer look, sniffed it, and felt a strange fragrance. He put his hand into the hole again, and reached above the opening, and felt it around.

He took out his hand, and saw a fingertip stained with black marks, which looked black and shiny, like an ointment-like thing, and put it in front of his nose and smelled it, and there was also a strange fragrance.

Tianci thought for a while and said to Daoist Buji, "Can you smash the stone wall above this cave and take a look?"

When Nabuji heard him say this, his eyes also lit up, and he said, "Yes, you can try it." So saying, he went to the side and took a large stone and smashed it against the stone wall above the entrance of the cave.

Knock, knock, knock, he smashed seven or eight times in a row, and saw that only some stone slag had fallen from the stone wall, leaving a few small pits, which were actually intact.

Tianci took the stone and tried it a few times, but it was still fruitless, the stone wall looked very hard, and it could not be easily smashed open.

"By the way, I have a solution. Tianci put down the stone and thought for a while.

"I went and gathered some firewood, and set it up on this mountain wall, and burned it with a great fire, and then we took some water, and poured it on the hot stone wall, and we might stir up the rock. Tianci said.

"That's all there is to it. Buzi replied.

After the discussion was settled, the heavens went to the woods to collect some firewood and put it on the stone wall.

Buji went and gathered some branches and dead grass, made them into a large basket, and then went to the stream and dug up some soil and pasted it on it, and made a large mud pot to dry in the sun.

An hour later, when the mud basin was almost dry, the heavens lit the firewood, and the fire burned violently on the rock wall for a while, and when the firewood was almost burned out, Buji filled the mud basin with a basin of water from the stream next to it, and poured it on the burned stone wall.

I only heard the sound of "bang la la", and a burst of green smoke suddenly came out of the stone wall, and when I looked at it again, a stone crack had cracked on the stone wall.

After they repeated this three more times, the stone wall was already cracked.

Buji picked up the big stone and threw it down on the stone wall, only to hear a loud bang, and the outer layer of the stone wall was smashed open, and several pieces of broken stone fell from the stone wall.

When they went up to take a look, they saw that the outer wall of the stone peak had been broken, and the inner rock was exposed, but they saw that the inside of the rock was covered with all kinds of cracks, extending from top to bottom.

Tianci looked down along the crack in the stone, and saw that the gap in the lower part was covered with black mud plaster.

He pointed there for Buji to see, and said, "Is this a refined elixir, it seems to be all stuck there." ”

Bu Ji leaned in and took a closer look, and suddenly felt a strange fragrance coming to his nose, and he couldn't help but be overjoyed: "Yes, exactly, I found it, I found it!haha...... Haha......"

After a burst of ecstasy, Buzi leaned down and used a thin branch, carefully, slowly, to pluck the black ointment-like substance out of the crack in the stone.

The Daoist priest of Nabuji lay there like this for more than an hour, and then he completely took out all the pills, crumpled them into a ball, the size of a fist, black and shiny, revealing a strange brilliance.

Buji held the ball of pill in his hand, and his eyes emitted a strange brilliance: "This is the miracle created by this sect in the past hundred years, Dingkun Divine Pill!"
