"I made Song Xichen into a fierce corpse and I made A-qing into the blind person she desired to be." He also cut out her tongue. But he leaves that part out. She had lied for all those years about what she was and it was partially her fault that Song Lan ended up showing up at their door. So he did what he felt she deserved.

But he doesn't hold back in what he says. There is no point in lying to the man. He might as well know and make his judgements.
