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?

The Special Investigations Unit is a covert organisation that no-one in the city knows about, dedicated to investigating bizarre occurrences beyond the comprehension of the living. The Chief Zhao Yunlan isn’t a simple guy either, being the inheritor of the Guardian Order, he has always been a righteous conformist, excelling between realms of the living and the dead. While investigating a school suicide case, Zhao is attracted to the calm and reserved Professor Shen Wei, but the Professor seems to be rather fickle towards him…

- Description from Novelupdates

Rhian Locke only wanted strength.To face the monster that slaughtered his parents while he watched, helpless.“I never asked to be your savior. So why should I care?”All he hoped for was to reach a decent rank, hunt that beast down, maybe become a monster hunter, and retire in peace.“I’m not a slave to the gods. I don’t exist to do their bidding.”But the world had made its decision long before he was born.“Patterns are meant to be broken.”------“Boy, I’ve bathed in the blood of your kind. I’ve crushed those stronger than you.”Lightning cracked across the sky. A hammer flew to the hand of a god.“I won’t let a deceiver’s spawn and a whore’s bastard son, stand before me and declare my end.”Rhian stepped forward, blood trailing from his mouth, eyes locked.“I’m not here to declare your end,” he said coldly. “I’m here to fulfill it.”....

A conversation with a handsome stranger leaves Ariane chained in a cellar with a strange affliction. She soon discovers that the darkness of the nineteenth century’s Deep South hides many dangers. Mages, wolf shifters and the humans who hunt them play a risky game where to stumble is to die, all under the amused gaze of the apex predators of the supernatural world: vampires.

It is never healthy to attract the gaze of the aristocracy of the night. It takes much to survive in this merciless world, but Ariane will not let that deter her. The southern belle has a bite, and she is willing to learn and to grow in this hostile new world. She will use whatever means necessary to reclaim her freedom, be it guile, charm, or those intriguing new instincts that make blood so delectable.

This is a story of vampires as I believe they should be, with their strengths and weaknesses, with their remnants of humanity and the beast inside. Updates every Friday. Mind the tags.
