Lin Yu became blind because of stargazing and entered Ye's family. He was humiliated by his mother-in-law Zhu Li in every possible way for three years. On the night of the summer solstice, he accidentally regained his sight, but he bumped into his sister-in-law Ye Kexin dressed coolly, causing embarrassment. He then fainted and received the "Star Jue" and "Nine Needles of Returning Yang" passed down by the old man Tianhuang. Coincidentally, his mother Zhong Xuehong was dying in a car accident. Lin Yu saved her mother with nine Yang-returning needles, which shocked the hospital director Sun Mingxing with his first show of medical skills. After that, Lin Yu practiced to improve his strength while practicing medicine and accumulating contacts, treating Du Xiaoxiao, the old man of the Xiao family, etc.
