Why not try alchemy with Earth Fire?
Jia Ren had always used Sunfire Wood for alchemy, and with this method, he had elevated the Proficiency Level of the Profound Water Pill to Master Level. This was a miracle unprecedented in the history of alchemy. Jia Ren had, in fact, attempted Earth Fire alchemy before.
However... Earth Fire was too violent. Without the Flame Control Pill Technique, it was impossible to precisely control the flame temperature. After several attempts, all had ended in failure.
Now in possession of the Flame Control Method Gate, he could abandon outdated practices and switch to Earth Fire alchemy.
Jia Ren returned to his residence, fed the Spirit Fish bait, and headed straight for his Cave. After paying the Spirit Stones, he rented the Jia Character Cave Residence, which had Earth Fire access.
The price was double that of the Caves he previously rented, costing two Spirit Stones per day.
