[Crossover] Passing Through the Planes

Terminally ill and waiting to die, Tang Baizhi has little to leave behind in this life besides his younger brother and sister. But before he can die, his little sister disappears ahead of him. Tang Baizhi, whose family is filthy rich, joins forces with his younger brother to search everywhere, but they can't find her. Then a System drops out of nowhere, and they learn that his sister may have gone to another plane. To find his sister, he kidnaps the System and travels to countless planes, putting up countless missing-person posters. But who could have guessed that every time he passes through a plane, things are perfectly fine, only for him to end up taking a knife or being blamed for something in the end? Tang Baizhi, tough despite his disabilities: Don't cry :), I'm still doing my best to find my sister today. Tang Baizhi: I'm just passing through. I'm not doing anything (^~^) Planes: I don't believe you.
