Throne of Chaos!

Even after making the Power of War a Man-Transcendent Principle, once confronted with the Evil Flux concealed in Taotie's mauve aura, Taowu suffered instantaneous obliteration—hinting that Huan Yi's Power of Evil was at least a World-Transcendent Principle…perhaps even higher! 

But despite having overpowered and destroyed Taowu in such devastating fashion, Taotie didn't feel the slightest trace of joy or satisfaction. On the contrary, as the Heaven Swallowing Peril lowered her fist, a sense of loss and emptiness spread inside her chest. 

At Taotie's back, Huan Yi stared at the Hunyuan Clock, showing no interest in Taowu's fate. 

The Four Primeval Tools had strong connections to the Four Perils. The Manuscript of Forbidden Secrets to Taotie, the Classic of Mountains and Seas to Taowu, the Compass of Four Extremities to Qiongqi, and the Hunyuan Clock to Hundun.
