Wu Guang: “Good grief! This rebirth entry is way better than everyone else’s—don’t you get an extra lifetime, or even several lifetimes? Everything you gain in a new world can be brought back exactly as it is? And every time you enter a new world, you gain another clone—doesn’t that mean extra lives?! Wait… why don’t you guys have this?”
