I started out transmigrating and becoming a god, but the system insisted it was Journey to the West!

Su Yichen, who transmigrated into the world of Journey to the West, initially thought he would cultivate immortality and become a god like many of his predecessors, becoming an ordinary celestial emperor. Until he discovered that this world seemed quite different from what he had imagined.
"Master, are you sure this is the Journey to the West world?" Su Yichen, who was in the Tang Dynasty, looked at Sun Wukong, who was fighting against Xuan Tianji with three heads and six arms in the sky.
"Ding! System detection indicates this world is the Journey to the West world!"
"Who are they?"
"Sun Wukong, Yang Jian."
"Then who is she?" Su Yichen asked, pointing to the angel Keisha in the sky.
"Ding! Detection confirms the other party is the sage Nuwa!"
