In Tik Tok, "King Wudang also visited Old Shi Tian". Where did this come from?

From the domestic animation "Under One Man", this passage comes from the second episode of animation season 2, 4 minutes 18 seconds. Old Shi Tian is the sixty-fifth generation Shi Tian of Shi Tian Mansion in Zhang Zhiwei. He is a ten-year-old boy. He is a leader in "one is the best, two are heroes" and was recognized as an excellent master decades ago. Wang Ye, a disciple of wu-tang clan (who has now left Wudang), is also a descendant of one of the Eight Wonders. Claiming to be a poor Taoist, he is actually the third young master of the boss's family of China Shipping Group.
