For someone of Lin Mu's cultivation base, a situation like this should have been enough to knock himself out.
Even if it wasn't from fear, just the sheer pressure of Qi and energies here would have resulted in the same.
As such, it didn't make sense why he was still standing. This was also enough for Holy Topaz Emperor to figure out that Lin Mu was the one being targeted by Feng Baxing and had survived all this without a single hair missing.
'For a Celestial to interfere despite the laws of the Immortal Court… just how valuable is he for such a favor?' The Holy Topaz Emperor wondered, having no idea that not only was Lin Mu behind Feng Baxing's current condition, but that he had also killed his eleventh son too!
Of course, even if he found out about it there was no way he would dare to act. Especially not until he figured out more about the situation and learned just what kind of power s were at play.
