Martial King's Retired Life - Book 13: Chapter 121

The world had changed when the System arrived, alongside the Cataclysm that filled the world with monsters. The technology was gone, replaced by classes and skills that allowed the people to fight back. When Devon ended up as a Blacksmith, a class that didn’t grant Intelligence, he had to face the reality, that his old career that he loved - mathematical sociologist - was over. Instead, he had ended up as yet another discarded member of the production class, overshadowed by the existence of the System Shops to the point of total marginalization. But, what if all he needed was to reapply his scientific thinking to the System...

He was confused, so he asked, “I have a car, a house, good-looks and money. What am I lacking in?”

This isn’t the struggle of an empire, nor the tempest of another world, and definitely not a cultivation story. This is actually a super serious (not really), super hard sci-fi novel about saving the world. Take what I’m saying seriously.(Don’t)

Okay, it’s really just a bunch of slippery leaders and their deceptive emperor having a fun time saving the world everyday.

An unmotivated otaku is transformed into the Emperor of an ancient intergalactic magic sci-fi empire, and with the aura of a stay-at-home dad, he is similar to an uncle who adopts an army of lolis. This is the hilarious story of an otaku and his freeloading army that appeared out of nowhere. Once again, this is a super serious story. This is a super-ultra-serious sci-fi story.

Have fun 😉
