After refining the Heavenly Heart Flame, Chu Zheng's cultivation in the Immortal Path had advanced further, entering the late stages of the Spirit Spring Realm.
Even for those with high-quality Immortal Bones, reaching this stage would normally require at least a few years of devoted cultivation.
For someone like Fu Quanliang with lower-quality Immortal Bones, if there were no elixirs to consume and one were to follow the orthodox path of cultivation, reaching this stage would take at least a century.
In just less than a few months, having refined Divine Fire twice in succession, Chu Zheng's cultivation had seen astonishing progress.
Such rapid advancement actually came with significant risks.
Refining Divine Fire was an extremely dangerous task, but under the repaired panel, these risks were forcibly smoothed over.
Just in the process of refining the Heavenly Heart Flame alone, Chu Zheng's body was dried out hundreds of times, nearly exhausted of its oil and burnt to the wick.
