The Eternal Number One Crazy Son-in-Law

Liu Feng marries into the Tang family, the least powerful of the four great families in Qingshi City. His wife is cold and aloof, his sister-in-law is hot-tempered, his mother-in-law is ruthless, and his father-in-law is a timid man afraid of his wife.

By chance, Liu Feng obtains the legacy of a mysterious powerhouse and comprehends a thousand-year-old sword intent and the true meaning of chaos. He gradually establishes himself in Qingshi City, makes a dazzling impression, and shoulders the burden of the Tang family.
