A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century.

Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory?

Ten years after her parents’ divorce, the grandmother who raised Chu Tingwu passed away, leaving her to be shuttled back and forth between relatives.At this moment, an entity claiming to be a “Cub Rearing System” suddenly appeared, wanting to bind itself to her and cultivate her into an outstanding graduate of its program.Just as Chu Tingwu was about to refuse, she saw her personal attributes on the system interface—[Name: Chu Tingwu][Species: Cat]Chu Tingwu: Something’s not right here…Due to a bug, the system had identified her as a kitten.Her stats were those of a cat, but her appearance remained human.How should an exemplary human-cat be raised? Sleeping, causing mischief, eating until she became as round as a pig?However, the reality turned out to be quite different: extreme sports, expert bird-catcher, master mouse-hunter, catching invasive fish barehanded with dynamic vision, using camouflage and tracking skills to film documentaries of rare birds, nearly making the social news as a suspected retired special police officer.For the first lesson in cultivation, the system said gravely:“A cub cannot live alone. We need to find you a cat mother… I’ve already detected a suitable candidate nearby. Go to the target location quickly, little one, and let the cat mother adopt you.”Chu Tingwu looked up as an advertisement fluttered into her hand:[Sunshine Pet Hospital: Limited-time half-price pet neutering, one month of free food with every pet adoption]Chu Tingwu: Who exactly is adopting whom here?

Chu Chen silently watched the group of system hosts who had been playing with the system he created to the point of collapse, and drank tea very calmly.

“You don’t really blame me for the rewards you get. I’m only responsible for the system delivery system. You blame me for being like this…”
