Pay Enough, and the Gods Won't Die in Thirty Seconds, or It's a Bad Deal

[Cthulhu Mythos + High Martial World + Smart Protagonist + No Mindless Power Fantasy + Decisive and Ruthless + Plenty of Twists] The stage is set for disaster. Even demigods are cannon fodder. In this age, there are undying ghosts, monsters that corrupt and warp perception, cunning and cautious demons, and omniscient, omnipotent gods. Humanity can only survive in the cracks between disasters by relying on professionals. Gu Ming transmigrates by chance. But the only thing he awakens is the F-rank profession [Bodyguard]. He goes from a celebrated prodigy to someone everyone despises. His brother steals his girl, his girlfriend dumps him, and his team kicks him out. But no one knows... Though his profession seems useless and low-ranking, he has actually bound himself to the [Myriad Heavens Professional Bodyguard System]! From the start, he obtains the Mythic Trait [Evenly Matched Domain: When activated, it ignores cause and effect, selects the strongest person in range, and forces them to fight on equal terms! It can stack with other skill traits while active, with no upper limit!] [Escort the Seraph back to the divine realm and obtain 'Heart of God: Awaken your divinity and receive the blessing of a god's status!'] [Seal ghosts and demons, and defend the crumbling edifice to obtain 'Yin-Yang Doppelganger': one yin, one yang, a god or demon with a single thought, inheriting the same traits!] So what if the ghosts can't be killed? So what if they are creator gods? As long as you pay up... even the gods will kneel before me!
