With a heavily damaged soul and the snarky remarks of a system, he began his years-long quest to recover his body.Armed with his mind, he'll educate the baby and slowly watch him turn into a good youth. However, he would have to make a choice: suffer as a ghost until he finds an alternative that might not exist, or possess his body and reincarnate.He was far from imagining how dangerous this world full of possibilities could be, prompting him to question everything he knew... Including himself and this world's intentionally blurred history.
