Three years ago, Lin Yuan, the "Yam Luo" in the underground world, mysteriously disappeared after a shocking battle, leaving behind countless legends.
Three years later, the Qin family in Tianqiong City gained a son-in-law who was known to everyone as a "waste". He endured ridicule and was willing to live in the mortal world just to keep a promise and protect her who was cold on the outside but soft on the inside.
However, when the wealthy families are in conflict and the storm rises again, the safety of the family and the dignity of the beloved are both hanging by a thread.
Lin Yuan finally understood that true protection is not about giving in and forbearing.
When he slowly raised his eyes, the ferocious dragon hidden in the abyss finally revealed its dazzling edge.
"I once walked through mountains of corpses and seas of blood, just to find peace."
"But if peace is broken, I don't mind... Creating another mountain of corpses and a sea of blood."
This is the story of a king of soldiers who returns to the city and sweeps away everything but devotes his tenderness to one person.
