In the methods of cultivation Chu Zheng had encountered so far, the Path of Incense Fire Deity was undoubtedly the shortcut among shortcuts.
However, the side effects were also quite evident, as the massive death of believers would lead to a decline in cultivation.
Chu Zheng's cultivation had previously fallen by two minor realms.
Most of the time, Incense Fire Deities were in slumber. If caught off guard and their believers were killed instantly in large numbers, it could significantly weaken their power, allowing them to be subsequently cut down.
On the other hand, cultivation piled up by a large amount of Incense Fire Willpower had a quite worrisome actual combat strength.
Leaving aside the extremely powerful Martial Path Chu Zheng had seen, just the Qi Refining Lineage and Immortal Path Cultivators alone, in a battle of the same realm, could take on five or even more.
