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. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. 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?

A new work from the author of 'My Senior Brother is Too Steady', welcome to enjoy it!-------[Science Fiction Apocalypse Setting + Alone Cultivation Protagonist, Not a Mindless Feel-Good Story]This is a shattered world where human civilization barely gasps for air on a planet ravaged by the Blade Beast catastrophe, the flame of civilization in underground fortresses flickers intermittently, and human elites in space are brewing a final plan to strike back at the Blade Beasts, but the future of humanity is dimly lit by fading stars…“So,”a Mahayana Realm expert, who after cultivating alone for one hundred and twenty-five years failed his tribulation and became a Residual Soul in this 'peculiar' world, sighed deeply as he looked up to the sky:“What the hell does this have to do with me?!”

There was a special patient in Spruce Hospital. A person in vegetative state and coma that the tree doctor, So Lee-yeon, has been hiding for two years…‘Don’t wake up. Please don’t wake up.’It was her dream to live quietly so she prayed every night. Then one day, by pure miracle or failure, the person in vegetative state woke up!“Did you come to suck this poor bastard’s dick?”In front of the man that lost his memory and common sense, she told a lie that couldn’t be turned as she was afraid of his mu*derous instinct.“I’m your w-wife, Kwon Chae-woo.”To the man who buried someone alive and tried to kill her two years ago!

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?
