On Our Wedding Night, I Discovered the Crown Prince's Hidden Illness - Chapter 20 - Be Diligent

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?

Hi there, I’m Chen Mo, as you’ve already noticed from my name, I’m a main character profile, or at least that’s how it was supposed to be. For legal reasons, I won’t be disclosing my real name, I’m a typical corporate slave working 996 at a game development company.Although I hate it, its not all that bad, I hop on with my non-existent friends every now and then doing the usual stuff, yk, cranking 90s, getting the Ws(never) and reading some dogshit wuxia novels with negative translations but I still make it work.That was my life until I was transmigrated into the world of cultivation and took over my boy Chen Mo’s profile RIP lol. Chen Mo’s your typical MC profile, yk, has talent, then gets spiritual roots removed or whatever, engagement annulled, just the usual stuff.Anyway, enough about that, during my transmigration, I somehow got to keep my programmer job, don’t ask how idk either. To pay tribute to my boy Chen Mo for taking his account before he had his heaven defying opportunity to take revenge, I’ll build a sect for all MC profiles in the world. Your engagement got annulled? here’s a cultivation system, your sect got destroyed? here’s a god-level cultivation technique, your spiritual roots are broken? here’s some more.

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?
