Chun really wanted to ask Nan about the seventh layer, but it would be hard to explain to Aileen, after all, he's never told her he has a clone.
Then forget it, it's not important, even Aileen has a clone; for an Angel to completely fall, having a clone probably isn't hard either.
Chun asked the important question: "What happened in the past hundred years?"
Nancy said: "The formula given by the City Lord started mass production, but one day there was an explosion accident at the medicine refinery, the toxic gas engulfed the whole island, and the entire island was hit with disaster. Then this tunnel also exploded, started flooding, from then on my memory broke off. I only know my task is to wait in the secret chamber for the City Lord—City Lord, please open the safe."
Does this mean only Fallen Angel Nan knows everything?
Holy shit, what kind of plot module is this, does this mean Black Flag Island must die, and even if I travel back it won't change history?
