The man who once stood at the top of the global mercenary and intelligence world (codenamed "Ghost") was disheartened by the death of his beloved and exiled himself to a small oriental city, trying to integrate into the ordinary. However, an "old will" that accidentally fell into his hands revealed an ultimate secret that could subvert the world structure. In an instant, all the top forces in the world - legendary mercenary groups, transnational intelligence agencies, secretive plutocrats and underground empires - all turned against him. He must use his most primitive wisdom and strength to fight a bloody path for the dead, the living, and the future of this world in this global hunt, and be crowned the true "king."
