So basically, what I gathered from the hints they're giving out was that Wa** Yi was Qin Xian's system before. Qin Xian as the contractual villain(??) got obsessed with his system but for one reason or another Wa** Yi wanted to escape and become human. He succeeds and Qin Xian probs goes crazy and breaks away as well, in favor of searching for Wa** Yi on his own. And now things are all sorts of a mess and they're back with the system but playing different roles. 🤔 That's my guess so far.
