The soul-binding had given Wang Xiao too many ideas.
Yanyan was the second test. He'd tethered her the same way as Yin Yue, familiar soul, easy to connect. Now he could tap into her dark energy, swing his sword with her essence fueling it, without fully devouring her.
A weapon on standby.
But every leash was also a risk. If she grew too wild, if she learned to pull against him… better to bind her now, when she was pliant, than wait until she was a disaster with teeth.
That was his role. The anchor. The center that kept these women from wrecking the world in their moods and rivalries. And if he had to cheat, manipulate, or tie their souls down in the dark, so be it.
A moment of negligence, and one day they'd turn on him.
"Y-Your brain's the size of a walnut! Stop annoying me!"
"Hm... Walnut?" Wang Xiao turned at the sound.
