Su Xiyue actually didn't know what the Black Qi was.
She picked it up during her fight with the three Great Elders of the Hundred Sword Sect, and had to use Spiritual Power to suppress it, which drastically weakened her strength.
Otherwise, how could she have been forced to such a point by Leng Ruyu?!
That heat didn't stop, weaving through every corner. Not only did her external wounds get some relief, but even the injuries inside—her Meridians, her Dantian—began to improve.
This…
How could it be?!
Su Xiyue was well aware of how severe her injuries were.
She was only at the peak Foundation Establishment Realm, but she had used a Forbidden Technique to forcibly display Golden Core-level power. Though she broke the formation, her Meridians and Dantian suffered tremendous damage.
She knew, even after returning to the Immortal Sect with abundant resources, she would need to recuperate for four or five years!
Only then would full recovery be possible.
