What worked in theory did not always work in reality.
All sorts of unforeseen accidents could happen in reality.
And as the person putting these theories into practice, my mindset and actions would directly affect whether they worked.
"The greatest difficulty in Soul Swap lies in hypnosis."
I explained to Li Fuguang, "My hypnosis usually exploits people's habitual thinking and weaknesses. I can hypnotize any ordinary person, but I might not be able to hypnotize Wu Huaqing. You know Wu Huaqing best. Anything unusual I do could arouse his suspicion."
"More importantly, you're the one Wu Huaqing is most interested in. If you left my body ahead of time, I'd be going to see him alone. He definitely wouldn't kill me. He'd only imprison me. In that case, even if I used Soul Swap, he'd merely be trapped inside my body. Nothing more."
"So you couldn't leave my body ahead of time. You had to come with me to see Wu Huaqing."
"But as long as you came with me, Wu Huaqing would deal with you first thing."
After hearing me out, Li Fuguang grew thoughtful. "So... I had to let Wu Huaqing seal me away, leaving him without any reservations and allowing your Soul Swap plan to proceed smoothly. Is that right?"
I nodded.
But he went back to fretting over the same question. "You still could've discussed it with me beforehand. Don't you trust me?"
I hurriedly said, "It's not that I don't trust you. If we'd worked everything out beforehand, I was afraid it would all seem unnatural and make Wu Huaqing suspicious. Besides, you... really didn't do anything before he took you down..."
Li Fuguang flushed and hastily argued, "That was because, because I was already missing one of my own souls, and... and I'd reincarnated.
