Three hundred years ago, the Abyss descended. Humanity took shelter in colossal dome cities, unaware that the Council was raising them like livestock for sacrifice. Tan Tianxing has been stuck at the weakest Body Tempering stage for three years. Burdened by his master's death and carrying a sealed black blade, he humiliates the aristocracy in a single battle and astonishes the entire city. Investigator Shen Xiaoxian, tycoon heiress Su Nian, and hacker Lu Pangzi join him in forming a resistance squad. After defeating formidable enemies and storming the Council building, he uncovers the truth about the Abyss. When the Council launches its sacrificial plan, Tan Tianxing finds the evidence needed to awaken the people. Drawing strength from ordinary people's faith, he transforms into a giant and severs the connection to the Abyss. With the deception finally exposed, he refuses to seize power and ventures alone into the wasteland, forging a legend of a Body Tempering warrior who slays gods.
