Three years ago, Lin Mo, the Dragon Prison War God, retired to honor a promise. He disguised himself as the live-in son-in-law of the Su family in Jiang City, enduring humiliation after humiliation. Bearing the "Supreme Legacy" System, he bided his time, waiting for the dragon to return and rule the four seas.
When his wife, Su Yingxue, faced pressure from her family to marry and Zhao Wuji, the young master of a powerful family, kept closing in, the System awakened. He cured the tycoon’s strange illness, intimidated the southeastern generals, and revealed medical skills that stunned the world. Those who had once looked down on him were shocked to realize that this son-in-law they had dismissed as useless was actually the Yama War God, who could command life and death and reshape the world!
Watch as Lin Mo wields the System like a blade, sweeping through the powerful families and settling old scores. As he stirs up a storm of bloodshed in the city, he also protects the hard-won love he has found.
