[BL - Mature Content] Yao Shen is a struggling actor, virtually anonymous to the public. That is, until the opportunity to star in an anticipated new cultivation drama comes along, and it finally seems like Yao Shen's fate is turning. The only problem? He'll be playing the love interest of 'movie Emperor' Xin Hulei -- the big star responsible for all his difficulties in breaking into the entertainment industry. Things only get worse when a 'Demonic Capture System' is activated after Yao Shen's first audition with Xin Hulei. Worse becomes worrying when Yao Shen realizes the events depicted in the drama might not be so fictional after all, and that maybe there's more to it than the System is telling him... --- Yao Shen: "What do you mean Xin Hulei is one of the Demon Kings? And it's my job to send him back to the demonic realm? I'm just a D-list celebrity, how am I qualified for this?" System: "There are rewards." Yao Shen: "..." Yao Shen: "Tell me more" --- hardworking, down on his luck, determined and witty MC with a short fuse x cold beauty, calculating and sly, blackbellied Demon ML, hellbent on revenge.

Synopsis: Certain things are not meant to be touched, especially ancient weapons of unknown origin. Meet our protaganist, Juin, a less than average human from Earth; a thin, well-known weakling who was afraid of his own shadow and was basically everyone’s favorite punching bag. An incident in the past made him even more of a wimp than before. One day, while being bullied, he accidentally summoned a demon from another world. And what made it worse was that… He had summoned a Daemon King from another dimension; one who had the emotional maturity of a teenager and the mouth of a sailor. With Juin's fear of basically everything and the arrogant Daemon King who was afraid of nothing, what would the 16-year-old's life be from now onward? With the help, guidance, and insult from the Daemon King, as well as other supernatural beings that kept popping out of nowhere, Juin soon learned that he had to either grow faster or die a horrible death. Along his journey, he met with all sorts of temptations and exciting adventures, as well as finding out that there was more to what he thought he knew about himself. At the end of the day, could the Daemon King find a way to separate himself from his vessel, or are their destinies more interlinked than they thought? xxx Note from author: Except for first chapter, which is a prologue and set in another dimension, the rest of volume one would focus mostly on Earth. The first volume would focus Lucifer and Juin's developments, especially the latter's development both in skills and character. It might seem a little slow pace at first, but that's because I'm trying to build a piece everything up one by one, giving you a better immersion as you journey through the Demon King's Cowardly vessel. Honestly, I would love to hear your opinions on the development of the characters and the world.
