The Devouring Dragon - Chapter 8: Jaxor

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.
