In the future, cataclysms will sweep across the world, a mysterious dark fog will cover the sky, and human society mixed with demons will be on the verge of collapse. I was once a low-level villain who was abandoned by the sect, and no one even retrieved a word of memory for me. Until one accidental day, the dragon soul hidden in the body for thousands of years awakens. Taming a dragon, making a contract, and controlling the phantom winged dark demon crow, this rising path of a magic slave is no longer mysterious in the face of my devouring talent. The month before the great destruction turned into a shocking secret: the black mist that caused the collapse of the sky and the origin of the dragon soul actually came from the same source of disaster! The endless suffering was at its peak at the beginning. Only after the fog covered my eyes did I realize that even though they destroyed me, I could still destroy their hope. I write the name of every light that is about to go out in this dark era.
