One moment, Luo Jing was at the brink of death after accidentally touching a power outlet while showering. The next, he was in the body of a man named Garen, with memories of a past he was never a part of flowing into his head. As he slowly gets used to the body of Garen, he begins to explore a planet beyond his own logical comprehension. His journey will see him go from surviving in a planet locked in the 20th century, to wielding secret techniques so powerful that they level cities overnight. However, his journey doesn’t end with Garen. Instead this is but the first of many bodies that Luo Jing will come to wield in his mystical journey between worlds.

Qiu Qiu was born into a scholarly family. He possessed great looks and a kind heart. His outstanding grades were just as praiseworthy as the cute dimple he exposed each time he laughed. His melodic singing moved the hearts of all, and his guitar-playing skills were down-right godly. It wasn’t long before the overbearing president, Fu Ruien, fell for him, hard.

Fu Ruien: Qiuqiu, I would like to ‘support’ you.

Qiu Qiu: Oh, so you’re going to support me financially?! Like a scholarship?! Yay, that’s great!

And so, the two happily made arrangements, utterly oblivious to the fact that they both weren’t on the same page…

…..Three months later.

Fu Ruien: Are you a numbskull?! If you’re not being ‘kept’ by me, then why the hell would you call me ‘Daddy’?!

Qiu Qiu: In my defense, I saw that you were a 40-year-old uncle who still hadn’t been married, so I just wanted you to actually experience the warmth of a family!

Fu Ruien: …???

Qiu Qiu: But even if you don’t have a partner, at least you have this bright, talented and handsome eldest son who’s there for you. I mean, just where in the world would you be able to find such a perfect son like him!
