The world's top mercenary "Shepherd" was seriously injured and retired after being betrayed. He infiltrated the border military camp under the pseudonym Jingwen and started as a cook at the lowest level. He wanted to secretly pursue the truth, but he was involved in the pursuit of overseas mercenaries and the conspiracy of ghosts in the military camp. When the dormant "Dragon Spine" system awakened and the thousand-year ancient martial arts inheritance was revived, he had to make a choice between the road of revenge and the responsibility of guardianship - this time, he fought for the people behind him.
