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?

[Mature Content]Khalifa Fei, a famed water mage, suddenly woke up into a stupidly enjoyable book about the undead.Although she transmigrated into a cannon fodder who didn't even have a name in the book... she really didn't mind.After all, how could she possibly miss watching the book she liked in the flesh??What she didn't expect was that there would be so many... distractions along the way.Would she even be able to prepare properly with all these men pulling her to bed?

Manchester United, once a dominant force in world football, finds itself struggling under Erik ten Hag despite having the financial power to rebuild.Big-money transfers fail to restore the club’s glory, forcing Ten Hag to shift his focus to homegrown talent.Among the overlooked prospects in the U18 squad is Leo Calderon, a 17-year-old central midfielder buried deep in the pecking order.Lacking physicality and dismissed by teammates as weak, Leo endures constant ridicule from those who dominate with strength and athleticism.But during one ordinary training session, everything changes—Leo suddenly sees passing lanes no one else can, angles of play invisible to even the most talented prospects.Yet, there’s a problem. His vision surpasses his ability. The passes he attempts don’t connect, his technique unable to match his newfound awareness.Coaches dismiss his efforts as sloppy, and his struggles continue. But one unexpected observer—a visiting League One assistant coach—notices something different.He watches Leo’s movements, seeing potential where others see failure.As Leo fights to prove himself in an unforgiving system, the question lingers—can he refine his raw talent before the club moves on without him?
