The underworld is incredibly dangerous, he doesn't want Sabobo, Qing Yang, and Hu Xiaoliang to follow him, planning to go there alone with Black Pot, hence he comes to learn Sabobo's spell.
——After all, Sabobo's mother and son have reunited, he doesn't want Sabobo to risk herself for him.
Sabobo also knows his purpose for learning the spell, she is moved, and says: "I'll teach you another one, called Lin She, it guarantees you're without worries. Even your father, I didn't pass it on to him!"
Chen Shi stayed in Gaoshan County for two days before mastering Lin She, he bows to Sabobo saying: "Sister Qiutong, tomorrow, I'm heading to the underworld to find my mother, you and Uncle Qing Yang must leave the Western Capital quickly, we'll meet again at Qianyang Mountain in Xinxiang!"
Sabobo nods with emphasis.
Chen Shi hands the Fox Grapes Mirror to Sabobo, saying: "Grandma, take this mirror immediately, travel a thousand miles east, wait for me in the mountains."
