A Professor of Magic at Hogwarts - Chapter 29: The Chamber of Thought

‘Royal Roader,’ the game that I ruled as an overlord was ending its service. Shit! It was my life’s only pleasure.

The last day! I used all of my strength and in-game connections to defeat the final boss monster, Demon Heros.

As a reward, I earned a Marble of Wishes.[Please state your wish.]My wish? [Royal Roader’s renewal as reality.]I was just joking. I really only wrote it as a joke…

The worst thing that Shui Ruoshan think he ever did? He wrote the story of “The Strongest King in History”.

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.
