After years of torture and torment in the most brutal prison in the Five Planes, the famous 600-year-old Demon Shepherd escaped along with several prisoners, taking advantage of a mysterious incident. However, the trackers that had been implanted in his body, Ka and Ba, caused him to be pursued everywhere he went. His plight got a lot worse when he stumbled upon a Key that the Heavenly Union seemed to desperately want. The bounty on his head skyrocketed; the whole world was after him. His life turned into a nightmare. He couldn't even shit in peace, let alone cultivate. And now, they have finally cornered him. Fortunately, he knows a Yantra, and his only chance to escape death is by... killing himself.
