The ones who died were all Soul Masters, who, despite being able to achieve the strength to fight against a Titled Douluo with the aid of Soul Guidance Devices, simply couldn't match the physical robustness of a true Titled Douluo. Under the sudden, terrifying momentum unleashed by Du Busi, they burst and died instantly.
Not just them, even the Dragon God Douluo Long Xiaoyao's strength plummeted in the face of the momentum burst forth by Du Busi, his face filled with shock.
"You crazy old poison, you're actually burning your life force. This will trigger your soul core to explode!"
