Mortal catcher Chen Du was born with a mutilated Dantian and had no way to cultivate.
In order to survive, he chose to receive a demon pill transplant and transformed into a half-demon walking in the dark night.
When he investigated a murder case, he found that all the evidence pointed to the "Xuanqiong Shangzun" who was the leader of the immortal world and admired by all the people.
Should he expose the truth and die together, or should he endure and lie dormant for the sake of the common people?
Chen Du chose the third path: he pulled out the broken knife from his back that was rumored to only kill demons, and pointed the blade directly at the sky above the nine heavens, filled with immortals and Buddhas.
