After being reduced to a beggar in the mortal world, he got the help of his mentor, Patriarch Subhuti, to reshape his body and return from hibernation under the alias Sun Ape. In order to save the monkey tribe from danger, he bravely traveled to the underworld, gathered allies from all sides, and faced the secret layout behind the Three Realms step by step. With the help of friends from the three realms, Sun Wukong breaks through the shackles and gets rid of his own inner demons. Finally, he returns to the name of the Monkey King, protects the peace of the Huaguo Mountain, and embarks on the westward journey again.
