I like the story but limiting his Yin Yang bloodline to fire and ice seems like massive disservice. Like singling out a tiny almost watery snow flake inside a huge snowstorm.
It already has been mention the power of his current bloodline is barely the tip of the ice berg. Naturally, Lin Xiang still needs to naturally progress his way to that point.
I hope him being heavenly ruler now he can stomp halfstep divine lords so they wont be able to bully the song faction or take the article of divinites or try to lock lin Xiang up To get his secrets or something
Good chapter though
