When the system creator was killed mysteriously, Lu Chen encountered an unprecedented paradox in his retrospection: a tampered memory, and a dead person staring at him. The truth is shrouded in mystery, and he finds himself entering a huge maze of lies, power and human weakness. Every step of his pursuit is questioning everything he believes in.
