Building the Strongest Undead Empire from Scratch - Chapter 375: Another race king?

In his previous life, the MC was a total degenerate—lazy, self-indulgent, and only skilled at gaming and skipping responsibilities. One day, he dies in a ironic accident.He wakes up in a magical world, reincarnated as Eryndor Sylvaren, the youngest prince of the Ethereal Elven Empire. The elves are a proud and noble race, and their royal family is bound by strict traditions of honor, discipline, and responsibility—none of which the MC has any experience with.Luckily, he receives the “Divine System of Degenerate Growth,” a system tailored to his flawed personality. He makes the same mistake of repeating his past life only to realise that this new life has so much in store for him. Mistakes have consequences for power.NOTE: This book is a slow paced action adventure story that explores a vast fantasy world. If you like weak to strong, harem growth, high stakes, dungeons and adventurers,with a compelling storyline you should give it a try.

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?
