What is the origin of the crazy old man in the sky and the park?

Old Madman: The Holy Land of Tian Xuan is the only survivor who attacked the ancient forbidden area. His stunts are the six major imitations and Tian Xuan's footwork in the karma boxing wheel (born out of the secret of "line", but left after the old madman got the complete secret of line). It was famous all over the world, but now it's crazy. Fan Ye was taken out of the forbidden area in ancient times, and later appeared in the Taixuan Sect of Wei State. Fell into a coma because of the failure to cross the void, and left after transformation. He became a young man and met Fan Ye and others in Tian Xuan. After telling him the secret news of "Xing", he went to Shenya with them to get the secret method. Later, he came to Wei Zixing domain and was inherited by the ancient Taiyin emperor, and then he changed again. Archaean creatures that attacked in the war were also destroyed outside the territory.
