Therefore, there was also the saying of cooperation between artifact refiners. There were three types of artifact refiners. The first type was when one person did not use any tools and guaranteed to use their own spiritual fire to refine the artifact. However, it was impossible to continue refining for long. Because the consumption was too great, they usually only made very simple and ordinary things.
The second way was to use a weapon furnace. A weapon furnace was a special furnace for refining weapons. It was guided and controlled by the spiritual Qi of the weapon refiner. However, the weapon refiner did not provide energy to the weapon furnace. The energy used by the weapon furnace was provided by crystals. The crystals could pass through the weapons and produce spiritual fire. Then, the materials would be refined. During the whole process, the Qi Practitioner only needed to control the fire, shape the spirit weapon, and inscribe arrays.
