Five years ago, Song Mo was framed by his ex-girlfriend Lin Xuerou. He lost everything and was forced to leave his hometown. Five years later, he returned with the gifted cute baby Song Xiaobao, only to find that Lin Xuerou had become the apple of the eye of the Song family, the top wealthy family in the imperial capital, while he was regarded by everyone as a "scumbag who abandoned his wife and daughter."
Song Mo wanted to keep a low profile and find out the truth, but unexpectedly discovered that Xiaobao had secretly contacted Lin Xuerou and recognized her as his biological mother. What shocked him even more was that Lin Xuerou already had a perfect fiancé - Lu Han, the number one son of the imperial capital.
In order to take back everything that belongs to him and give Xiaobao a complete home, Song Mo decided to take Lin Xuerou back from Lu Han. But every time he tries to get close to Lin Xuerou, he encounters obstruction from mysterious forces. As the investigation deepened, he discovered that the man behind the frame that framed him was actually related to Lin Xuerou's adoptive father, and Lin Xuerou did not seem to be as simple as it seemed.
When Song Mo finally found the opportunity to confess the misunderstanding to Lin Xuerou, a bigger conspiracy was brewing secretly. The mysterious organization "Shadow" is eyeing the ancient martial arts inheritance in Song Mo's body, and the mystery of Lin Xuerou's life experience also involves a shocking secret that can overturn the entire Chinese martial arts world.
