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?

Lucy Gray was a tech genius—until a stranger smiled, pulled the trigger, and ended his life.But death wasn’t the end. It was a recruitment.Dragged before a pantheon of ancient gods, Lucy learns his soul has been drafted into the Holy War—an eternal bloodbath in which Gods fight across shattered realms. Out of thousands, he was soul #4,000, chosen by Seraphine, the Goddess of Rebirth and Suffering.Now reborn in a dying world of Ogres, Giants, Beastkin, Dragonkin, and Elves, Lucy is a human among legends—a species exiled and nearly forgotten, for reasons that make him hated.Armed with nothing but defiance, sarcasm, and a bizarre ability to steal and master the powers of others, Lucy has one job: survive the impossible.The gods wanted a pawn.They got the wrong dead man.

Murong Lingran, who was originally an ancient person, accidentally traveled to the 21st century and lived for 20 years. She was killed when she was bumped and killed while trying to save her child on the way to moving house.

She returned to the ancient times and saw her original family again. Before she could rejoice, she found that she was being swept out of the house, and their family was injured and scattered, and they didn’t even have a place to live.

She clenched her fists, it doesn’t matter, there is space behind her and the omnipotent gods and beasts help, no matter how big the difficulties are. There will be money, houses, fields, manors, shops, and family reunions. It’s just that she didn’t expect that she would accidentally hug the thickest thigh, the kind that doesn’t want to be hugged.
