MTL - The Demon Lord of the Shadow Queen - Chapter 10 learn the truth

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

When the game reappeared in reality, the world went crazy.

Shang Yinhe originally thought he was just playing games, until he horribly discovered: All the games he has played are reproduced in the real world!

The world turned to a strange trajectory.

Expert: There must be a mastermind behind the earth’s change!

Shang Yinhe: That’s me.

Crowd: The brave man who saves the world has a beautiful face!

Shang Yinhe: That’s me.

Earth: Thanks to the Guardian Alliance for protecting me.

Shang Yinhe: That’s me too. #It’s me, it’s me, it’s me#

- Description from Novelupdates

Set on a giant, almost finished bridge between Sadogashima and Niigata. Abandoned by the government, the bridge, and the giant man-made floating island at the center, has become a city of criminals and societal drop-outs.

Set in the same world as Durarara, but 15-20 years later. There is almost no overlap between Etsusa Bridge and the other novels.

It’s the vacation of a lifetime, a trip to a remote island filled with geniuses and murder.
