Sabak, the legendary city that dominates one side, has reached the pinnacle of its military power under the rule of the tyrant Wu Sheng, who used his dragon-slaying sword and iron-blooded wrists. However, absolute power breeds absolute arrogance and suspicion. Wu Sheng regards tyranny as the only truth, suppresses all dissenting voices with the dragon-slaying knife, and deeply implants fear into the foundation of the city. The deputy city lord Shadow Fang, a careerist who lurks in the shadows, keenly captures the cracks and resentments that quietly spread under the high-pressure rule. He carefully weaves a cobweb of betrayal, secretly unites with foreign enemy forces that have been coveting Shabak for a long time, and patiently waits for the opportunity that can subvert everything.
