The merging process of two flames was incredibly easy.
Why?
Because of his superior control over his mana. The Harmony of Nine Phoenixes didn't just give him high-quality mana.
It also made his control superior. After all, he was going through enlightenment for even a few seconds in every dual cultivation.
Superior added a different meaning than stronger because his upper limit of control was increased while also increasing the base limit.
A normal cultivator couldn't control his mana until he reached the Treasured Body Realm. In that realm, one would generally start learning to control their mana.
Upon reaching the Soul Sublimation Realm, that kind of control would increase exponentially thanks to the awakening of their spiritual sense.
Spiritual Sense was a sixth sense that allowed cultivators to see beyond others' cultivation and communicate through thought.
