His father disappeared here when he was eight years old.

Old Liu suddenly remembered his father's murmur before his death: "When the Liu family's blood meets the mind-breaking mirror, the century-old conspiracy of light and darkness will restart." Before he finished speaking, the glass in the entire city began to twist and deform, and countless mirror faces emerged from the void, giving out a sneer of shadow: "Descendants of the Liu family, are you ready to become a sacrifice of the mirror civilization?"
