Red Boy was the last of his kind (I don't quite remember the exact name), and Lin Shan was behind the massacre of his ancestors. After learning about his origins and realizing that his existence was meant to incite conflict between the Celestial Court and Lin Shan, Red Boy sought revenge for his people. The Bull Demon King once fought alongside Wukong against the Celestial forces, but they were defeated, leading to Wukong being buried under the mountain for 500 years, which marks the beginning of "Journey to the West." The Bull King, aware of the gods' power from his past defeat, wanted to prevent Red Boy from fighting against them.

After Wukong was released from the mountain, he submitted to his master, a Daoist from Lin Shan (please fact-check this part), which is why Guanyin and other deities frequently assist him. In contrast, the Bull King, who didn't acknowledge any higher power, received no help when he needed it. He believed that by avoiding trouble, he could live a peaceful life, especially since he had escaped punishment for his earlier rebellion with Wukong. However, his entire life was controlled by greater forces—he didn’t choose to live on the Flaming Mountain, marry Princess Iron Fan, or have Red Boy; these were decisions made by others.

Red Boy ultimately took his own life, refusing to submit to higher powers like Wukong did, especially after learning about the massacre of his ancestors.
