In front of me is a wide rock cave, this cave is hundreds of zhang in size, about five or six zhang high.

The entrance to the outside world of this cave is located at the top of the cave, and it is a cave that can only be walked through by one person. It's just that the top of the cave has been blocked, and you can't see the other side of the hole. A series of stone steps are carved into the stone wall below the entrance of the cave, which leads diagonally to the bottom of the cave.

In the middle of the cave stands a huge furnace the size of a three-story attic. This Ding furnace is a common three-legged and two-eared round tripod, and the two ears at the upper end of the Ding furnace have touched the top of the cave.

And directly below the Ding furnace, there is a hole several zhang in size. The entrance of the cave is only one circle smaller than the three legs of the giant ding, and if the position of the cave entrance is larger, I am afraid that the entire giant tripod can be swallowed into the hole.

Yellow earth fire mixed with colorful smoke erupted from the mouth of the cave and hit the bottom of the giant dome. Under the action of the Ding furnace, only the extremely pure bright yellow earth fire entered the Ding furnace, and those colorful smoke remained at the bottom of the Ding furnace.

At the top of the cave facing the Ding Furnace, there are dozens of narrow passages. The pure earth fire in the Ding furnace is transported along the passage to the various earth fire houses.

Suddenly, a stream of fiery red magma rushed out of the mouth of the cave and rushed towards the bottom of the giant tripod like an angry wave, as if it was about to overturn the giant tripod. Under the impact of magma, Juding made a sound like thunder.

At this time, a layer of pale white spirit patterns suddenly appeared on the ground of Juding and the cave. The spirit patterns that emerged on the ground were centered on the cave entrance and distributed in a circular shape, and these spirit patterns were extremely widely distributed, extending to the edge of the cave.

After the spirit pattern appeared, the giant tripod immediately became stable, and the muffled thunderous sound quickly disappeared. Then these emerging spirit patterns slowly fell back to the ground and into the giant ding.

When the magma retreated into the cave opening, the brilliant smoke gathered at the bottom of the giant dome disappeared, as if it had been completely absorbed by the magma.

And there seems to be an invisible prohibition on the periphery of the Juding, whether it is earth fire, bright smoke or magma, it cannot escape the confinement of the Juding, and not a single trace can float outside the Juding.

When the giant tripod transforms the earth fire, it is also like a huge furnace, exuding amazing heat and fire spiritual power, making this cave extremely hot and full of rich fire spiritual power.

In this environment, even the monks did not dare to stay longer.

At this time, a monk was sitting cross-legged not far from the stone steps, meditating. The monk was naked, and his skin had turned red in the heat, like a steamed crab.

In the process of meditation, this person sometimes enters his body with countless fire spiritual powers, and sometimes expells these fire spiritual powers from his body, and so on and so forth.

In the process of absorbing and releasing the fire spiritual power, this person's muscles and bones kept twisting and staggering, and there was a sound like plucking the bowstring, which made people marvel at the amazing power hidden in this seemingly thin body.

If someone else saw this, they would be shocked. You must know that when other people come here, even if they are wearing Taoist robes that have the effect of repelling fire and cooling down, they still dare not stay longer. Not to mention meditating and cultivating here like this person.

After a while, the man finished meditating, got dressed, and took out a brush and a jade bowl filled with a dark red liquid from the storage bag.

Then the person held a brush in his right hand and a jade bowl in his left hand, and quickly walked along the spiritual patterns on the ground, and from time to time dipped the brush into the liquid in the jade bowl and pointed at the spiritual patterns on the ground.

Under the light of the earth's fire, it was seen that the spiritual patterns that appeared on the ground were not transcribed on the ground, but inscribed in the ground, about half an inch deep.

Every time the brush doesn't touch the ground, it gets in the way and can't fall down. At this time, a strange spiritual power will be wrapped around the outside of the brush, so that the brush can easily fall into the spirit pattern.

It turned out that the sunken spirit patterns on the ground were already filled with dark red liquid, but in some places the liquid in the spirit patterns had become scarce, so a brush dipped in dark red liquid dots was used to "replenish" these spirit patterns.

The spirit patterns on the ground are constantly exposed to the scorching heat of the earth, and they wear out very quickly, so they need to be checked and repaired frequently. If normal methods are used, a formation mage needs to stay here all year round. This method of liquid filling makes the repair extremely simple, requiring only one ordinary monk.

After a while, this person arrived near the Ding furnace, and under the light of the earth fire, he saw that this person was Xiao An.

Xiao An looked up at the huge Ding Furnace in front of him, and some smoke had gathered at the bottom of the Ding Furnace again. These gaudy smoke is the fire poison that everyone avoids like snakes and scorpions. As long as an ordinary monk is contaminated with a trace, the spiritual power in the monk's body will become dirty, and if it is not dealt with in time, it will leave a serious hidden danger.

It is said that in some slightly larger sects, several places will be reserved to collect fire poison when refining the furnace that filters the earth fire, and these fire poisons can be one of the best substances to increase the power of magic weapons when refining special magic weapons.

As early as two years ago, Xiao An had participated in refining workshops many times in the sect and officially became an "apprentice-level refiner".

After that, Xiao An can finally justifiably take over the task of refining weapons from the sect, and the task of "guarding the earth fire" is what Xiao An has taken over since last year.

Xiao An didn't take over this task for the contribution points or spirit stones, but the things that the Nameless Master's notes emphasized.

According to the records of the nameless master, as a refiner, he must find a place to cultivate at the Earth Fire Spirit Vein during the Qi refining period. Because only in this environment, the "Fire Alchemy Golden Body" exercise can be cultivated to a small level, so that you can smoothly absorb a spiritual fire into your body when the ninth layer of qi refining is complete.

"Unknown Master" is Xiao An's name for the monk who left refining materials in the secret room.

The refining materials in the secret room were obviously carefully edited, systematically sorting out the refining knowledge learned by the Qi refining period cultivators. But for some reason, this person did not leave any information about himself, so Xiao Anxin could only call this mysterious person "Nameless Master".

Xiao An had already participated in several explanations of refining in the sect, but found that the information left by the "unknown master" was much better than the content explained by the sect.

According to the records of the unknown master, the time it takes to practice this exercise to Xiaocheng varies from person to person, with some people taking half a year and others taking two years.

When Xiao An saw this news, he at first just took it as a joke. Because this kind of statement is unheard of in the local area, and the elders of the sect have also said many times that only when they reach the foundation building period can they choose a spiritual object with the same attributes as their own spiritual root to incorporate into their body.

But later, when I looked at the "Fire Alchemy Golden Body" exercise, I found that this exercise was extremely mysterious, which made Xiao An have some faith in the statement that the spiritual fire can be absorbed into the body during the qi refining period.

In order to confirm this, Xiao An returned to the library and checked all the books about the monk's experience. To Xiao An's surprise, whenever the relevant content is about to be mentioned in the book, there are several pages missing from the subsequent content.

At first, Xiao An thought it was caused by poor preservation, but later found that more than a dozen books were like this, which made Xiao Anxin have doubts. Could it be that the sect did this on purpose, but why did the sect do it?

Suddenly, Xiao Anxin had a flash of inspiration, remembering the last birthday celebration of Kou Gongzi, and the descendants of those sect managers in that event. If the sect deliberately concealed something from Xiao An and the others, these people would definitely not hide it from their descendants.

Suspicious, Xiao An quietly bribed a monk in the Pepsi Hall to check the status of the "Guarding the Earth Fire" mission over the years. In the end, it was found that in the past ten years, there have been several gaps in this mission, each time it has been empty for about half a year, and the longest time has been empty for more than a year.

The task of guarding the earth fire is the least popular task among all the tasks released by Pepsido, although the sect has also issued robes with the effect of repelling fire and cooling down, but the effect of this robe is too poor. After each maintenance of the ground fire, it is roasted on the outside and tender on the inside.
