Comments of chapter undefined of Transmigrated Scoundrel's Exchange System

I think this is what happened: She is sovereign of equality came to lower worlds to spread her dao to empower herself when she came here and get entangled with the guy who cultivates the life dao and karma dao (this dude suppressing his realm to cultivate here) This man want to get her treasure so he somehow with his powers make her owe huge debt to this world so she can't escape from here (I dont understand why) When she realize this she put the debt to treasure and order to treasure to find someone who can carry the debt and repay it from another world. This is how Han Cai get the system or treasure. Now she wants to take the treasure back and got away from here and put all the debt to Han Cai. She was waiting him to use the treasure but he didn't use it so she poisened him with wine and kiss him and get his now karma (karma of him using the system after born as Yan Kai because I guess his karma of Han Cai is paid woth that river water torture thing) so han cai sometime make a second soul hide it in his first soul so he can move after she take away the half of the treasure (I am not sure at this part) and make a marriage contract with the witness of the dao of harmony so she can't harm him. But he stil owes huge debt to this world and he have half of what she has.This chapters are both a huge info dumb and plot reveal. I probably misunderstood some parts. I would appreciate if you could help me with those parts.Sorry for my grammar and other mistakes.
