Wukong had secluded himself for cultivation, laboring over the "Blood God Sutra" for several days, while the Daoist Equal to Heaven also devoted himself to the rigorous practice of the "Sutra of the Other Shore," both having achieved some progress.
Upon emerging from seclusion, they found four other brothers, the third being Peng Demon King, the fourth Lion Camel King, the fifth Macaques King, and the sixth Yu Rong King. Macaques King and Yu Rong King, aware of Wukong's bold intrusion into the Underworld to adjudicate the lifespan of the monkeys, admired his audacity and thus accompanied each other to pay him a visit. Wukong promptly laid out a banquet to host them. As they were all great demons by rank and hearty in character, they found joy in their conversation and subsequently swore brotherhood.
