Coming into His Own as a Treasure Refiner

The next day.

Cheng Buzheng left his Cave Mansion and headed straight for the shop Ma Chang had opened.

After meeting up, the two headed together for the Earth Fire Chamber in the Immortal City.

Although cultivators could refine artifacts and pills in their Cave Mansions, the spirit fire created with their magical power could not compare with Earth Fire, whether in purity or temperature.

Only after breaking through to the Golden Core Stage could a cultivator match Earth Fire, unless they obtained a Heaven-and-Earth Spirit Flame.

But whether a cultivator advanced to the Golden Core Stage or obtained a spirit flame, both required them to sustain it with their own magical power.

For extended pill or artifact refining, it was best to use an Earth Fire Chamber. Not only could this greatly improve efficiency, it could also better temper the Spirit Pills or artifacts produced.

Of course.

Heaven-and-Earth Spirit Flames were an exception!

But refining with a Heaven-and-Earth Spirit Flame consumed a great deal of magical power, making it impossible to keep going for long. It was the best choice only for a single artifact or a few batches of Spirit Pills.

Likewise.

Earth Fire had its shortcomings: it was less stable than spirit fire produced by a cultivator!

But for Alchemists and Artifact Refiners with ample experience, these issues were nothing. They mattered only to cultivators with limited skill in the Immortal Arts.

For Artifact Refining masters like Cheng Buzheng and Ma Chang, controlling a little Earth Fire was as easy as child's play. It wasn't worth mentioning!

That was why Cheng Buzheng had come to the Earth Fire Chamber to refine the Godly Extreme Pill.

Before long.

The two walked together into the Earth Fire Chamber's main hall, and Cheng Buzheng immediately rented an Artifact Refining Chamber.
