Journey to the West: I, Sun Wukong, Vow Not to Become a Buddha

I read a book, which said that Sun Wukong was actually the witch god who existed when Pangu opened the sky. He was Pangu's exquisite heart with seven orifices. He was plotted against him and transformed into a colorful sacred stone. As a result, Nuwa took the opportunity to patch up the sky with the sacred stone, which caused Sun Wukong's strength to decline after he woke up.
