Rod didn't care: "Don't worry, Book. If Asa is correct, the Supreme Will is the ultimate evil. As long as we sever the connection between the ultimate evil and the Black Ring Seal, perhaps it won't be able to influence evil thoughts anymore."
The puppet calmly said: "The master is right. The control of evil thoughts by the Supreme Will seems identical to the source feedback. Perhaps, to utterly defeat the ultimate evil, we'll have to rely on Asa."
Rod gave a faint smile. It's not an unlikely scenario, but if it truly comes to that, wouldn't saving the world be shit?
"That's really a terrible thought. Hopefully, it won't come to that."
The Book of Knowledge furiously flapped its pages, as if it had already caught its stench: "Stop saying that. Quickly forget this terrible thought... Master, besides needing to possess adequate [Source Carrier], you also require sufficiently powerful Spiritual Energy."
