Karma wasn't just bondage, it also represented orthodoxy and legacy, even if a true sect was destroyed. As long as someone inherited this legacy, he would become the new Sect Leader of Xuanwei Sect and rebuild it.
So the root of it all was here, and the Sect Leader of the Xuanwei Sect had placed this root on Gu Shanhai, seemingly using him, but in reality, he placed the entire lifeblood of the Xuanwei Sect on him.
"First, your sect will cool down then I'll take your karma away."
Now, he couldn't accomplish these, but in his past life, he could.
Even if he couldn't obtain the complete strength of his previous life through the Previous Life Biluo, replicating even a tiny fraction was beyond the resistance of this world's karma system.
Gu Shanhai wasn't just acting out of spite, there were benefits too, otherwise, he would have gone miles to hunt down the Xuanwei Disciples.
The most valuable thing in this world was indeed karma.
