Ye Chen, the adopted son-in-law, was bullied by his mother-in-law and his family due to amnesia, but he secretly awakened the memory and super combat power of the Dragon King in his previous life. He endured it for three years, then broke out on the night his wife was forced to divorce. As the Dragon King, he crushed the provocateurs and discovered that his mother-in-law's family was actually colluding with traitors from the dragon clan, their old enemy. While pretending to be a pig, eating a tiger and slapping his brother-in-law in the face, Ye Chen secretly unified the underground forces, finally revealed the truth about his brother's betrayal, and returned with the dragon army as the king to protect his wife, daughter and peace.
