My Wife and Daughter Despise Me, but I Become a Master Doctor of Chinese Medicine. Why Are You Crying?

For six years of marriage, Lin Feng gave up his name and lived in obscurity, devoting himself to caring for his wife and daughter. Yet despite his wholehearted devotion, his wife and daughter still despised him. Only when he asked for a divorce did they discover that Lin Feng was a reclusive master physician of the nation, with an astonishing background! You treated me like dust back then, and now you kneel and beg for my forgiveness? Sorry. Affection that comes too late is worth less than grass.
