The small flame landed on his Golden Core, as if the Golden Core caught fire.
Just when Li Yuanba thought it was all over, he acknowledged the small flame as its master. Energy transmitted from the void, the energy was Supreme Yin in the void, but transformed into Supreme Yang when it entered his body.
This was a special ability of his Taiji Dao Body, the energy seemed to inject vitality into the small flame, and the small flame quickly began to grow.
He perceived for a moment, only to realize that the energy from the void was coming from the 'Xuanyin Ghost Fire'.
Normally, in his human state, without the presence of a Spiritual Fire with Supreme Yang attributes, the 'Xuanyin Ghost Fire' wouldn't be affected by the Taiji Dao Body.
Once the Spiritual Fire is acknowledged as its master, it becomes a part of the cultivator's body, and when conditions are met, it would also be influenced by the Taiji Dao Body.
