The male protagonist is an ordinary, somewhat reclusive man whose days are spent in the monotonous cycle of going to work and coming home. He has no idea what the meaning of life is and has always wanted to find his true self.
By a twist of fate, he transmigrates to another parallel world, where the An Lushan Rebellion is underway. There, he is still just as ordinary, but he encounters different people, different events, and a different world.
Can he find his true self there?
