In the wasteland era where civilization collapsed and radiation dust was forever shrouded, the remains of the old world nourished ferocious mutated behemoths and twisted ecological hell. Survival is the only belief, and strength is the only currency. Lieyang, a top hunter who is as silent as a rock and carries a mysterious past, walks on the edge of extinction holding an ancient "bone blade" that contains ominous power. He is not a lone wolf. The heroic and loyal robot-arm warrior Black Falcon is his brother in life and death; the cunning and agile technical genius Red Scorpion is his indispensable eyes and ears; and the calm and wise pharmacist Qingdai maintains the team's shaky lifeline with her wisdom and medicine. The "Setting Sun" team they formed hunts in the jungle of steel and flesh, exchanging the remains of mutated giant beasts for "protein blocks" that sustain life. Every time they swing their swords, they are dancing with the god of death. Let us walk into the difficult path of survival of the setting sun team in the wasteland.
