I Am a Demon Ancestor in Journey to the West

The golden light slowly dissipated. There was one more person at the entrance of the water curtain cave. No, not people. That's a monkey. A completely different monkey from Sun Wukong. He was slender and covered with jet-black hair, except for a strand of golden hair on his forehead, like a crack of lightning. His eyes were deep purple, and his pupils were like bottomless vortices that seemed to be able to swallow up all light. He wore a broken black armor, covered with cracks and knife marks, as if he had experienced countless tragic battles. The right hand is holding a long stick that is completely black. Dark red lines can be faintly seen on the stick, like solidified magma. He stood there without making any unnecessary movements, but the aura of the entire world changed. The air became heavy, and the heavenly soldiers and generals found it difficult to breathe. Even the powerful men like the Four Heavenly Kings began to tremble involuntarily when they held the magic weapon. This is a fear that comes from the depths of the blood, just like the instinctive trembling of an ant when facing a giant dragon. Sun Wukong stared blankly at the black monkey, and suddenly his only eye widened: "You... You are..." Black Monkey looked down at him. There was not much emotion in his deep purple eyes. He just said lightly: "Thank you for your hard work, fellow man."
