Born with a Yin Body, He Is Haunted by the Demon King Every Night

In the morgue, the corpse sat up suddenly, its scarlet eyes locked on Mao Youning. It is not here to kill, but to "replenish". Mao Youning is the 180th generation descendant of the Mao family, a walking elixir, and the flesh and blood coveted by all demons. But they don't know that Mao Youning is just a forensic doctor with low magical power who relies on his ancestral jade pendant to survive. Until that day, Mao Youning retrieved a dying nine-tailed fox from the crime scene. He took human form and was as handsome as a god and as domineering as a demon. He forcibly moved into Mao Youning's house, declared that Mao Youning's body was his "antidote", and demanded money every night, forcing Mao Youning to practice double cultivation with him to extend his life. He blocked all the deadly evil spirits for Mao Youning, but he also locked Mao Youning tightly like the most sophisticated shackles. At the same time, the male ghost who has been guarding Mao Youning for hundreds of years is getting more and more anxious. He seems to know this man, and desperately delivers a broken warning to Mao Youning - "Don't believe him... He will... Kill you..." Mao Youning was trapped in a giant web woven by love and murderous intentions. One is the thousand-year-old demon king who has robbed Mao Youning by force and is intertwined with Mao Youning's life. The other is the old obsession that silently protects Mao Youning but makes Mao Youning weaker day by day. Who should Mao Youning trust? Or maybe... None of them are here to save Mao Youning?
