After Marrying a Vegetative Princess, I Went Crazy With Joy! - Chapter 237:

Fifty years ago, Dragon City transmigrated to the Other World. Alone in the world, they lifted the banner of Earth’s civilization and fought against the terrifying forces of the Other World.

Leon and his father, Artorias, are the last remaining scions of a once powerful and illustrious family of lightning mages. After barely surviving an attack that destroyed their home fifteen years ago, they now live in the dangerous Northern Vales, a desolate wilderness far away from civilization. But those who want them dead are strong, patient, and relentless, and it is only a matter of time before they find the two they seek...

The maniac who was crazy about all kinds of fields such as military and steampunk had been reincarnated.

However, his father was King Sejong the Great?

The mania-wise king and his crazy maniac son.

Along with the ministers, and countless humans who were getting exploited.

Even today, the night of Joseon was filled with the light of overtime.

The world ended, and from its ashes, a new society rose. One where strength was law, and the weak were nothing more than dust beneath the feet of the powerful.Malakai Von Sanguine was meant to be great, a direct descendant of one of the grand families of the dome, the Sanguine Clan. But at seven, he lost everything: his parents, his future, and his ability to evolve. Branded as worthless, his life became a living hell, forced to survive in a world where the unevolved were walking corpses.But fate wasn’t done with him yet.One fateful encounter changed everything.He evolved.What he acquired was something far beyond the limits of his clan, something most wouldn’t believe possible. A power that defied the very laws that governed their new society.Now, there is only one goal: revenge.The people who took everything from him… he will hunt them to the ends of the earth. He will burn their names from history and carve his vengeance into their very bones.No mercy. No forgiveness. No escape.They will die screaming.Or he will die trying.
