At first, Tang Xiao's life was very happy and peaceful, but everything changed when he was five years old, and his parents were murdered before his eyes, leaving only him and his big sister, Tang Yin. In addition, Tang Xiao was framed by several people when he was 17 years old, and one of them was the person he really trusted, so he was forced to spend 7 years in prison.

However, Tang Xiao was fortunate because someone saved him, but the events of that day changed his life and mindset completely, and he used everything in his arsenal to take revenge on his enemies.
