"Master, you have a point. If my senior sister came to investigate me, we'd certainly be innocent. All the blame would fall on others, and I could then plausibly feel compelled to join the Devil Sect."
Ji Changsheng was a reasonable person. He thought the Master made sense, so he was quickly persuaded, thus recognizing his own foresight.
"Master, do you notice how considerate I am? To infiltrate the Devil Sect, I deliberately did the job of framing and smearing so clumsily, just so people could tell at first glance. In this way, the investigation team would have reason to expose my actions, and I'd have a sufficient reason to gain everybody's sympathy when joining the Devil Sect. When I'm forced to join the Devil Sect, you can use this opportunity to take action, to build a good reputation against the Sword Immortal Yi and the Heaven Connecting Commerce Association."
