I Was Just a Cleaner... Until I Got the Demon Extraction System - Chapter 61: Things didn’t go as Planned

[1V1 easy read, a pampered romance] Time-traveled straight into a wedding, does it have to be this intense?“Hey, hold on, groom, I'm not your bride!”Su Pan'er fiercely resisted.Someone chuckled craftily, “Quit messing around, my dear wife!”This story is fantasy, don't compare it with actual historical context. Recommended another novel by Dou Dou: “Joy of Being a Mother in a Farmhouse”.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

Imagine being forced to live, after death, as incorporeal bodies trapped in a vast space of nothingness for thousands of years, with nothing to do but exchanging past memories with other cohabitants (read: weirdos). Everybody wanted out, but there was no way to leave the Void…

Until one day, a young man was finally summoned, as a powerful but reluctant mentor, by a bubbly and motivated but completely naive young girl. Baiyi, finally out of the Void, was the only one who could save all of the other 32 souls from their prison and his summoner might just be The Key to their freedom.

However, Baiyi had to use the techniques and abilities the other souls had taught him throughout the years, and together with his own extensive knowledge of anime and game tropes from his shady and dangerous past as an otaku, to face the biggest challenge of them all: training the clumsy young girl he was forced to partner up with… into a competent sorcerer!

This is a story of heroic adventures, cunning strategies and romantic tales. How will our MC thrive in a world completely strange to him? Where will his ambitions and abilities take him in the palace?

I am the foremost disciple of the Great Namgung Clan, Namgung Qinghui!”But it seems there is a bit of a misunderstanding.This isn’t a spell for dimensional travel, kids. It’s fiction…
