Shi Feiyu, who was practicing the Divine Fiend Incarnation Skill, didn't display any Natural Source Qi fluctuations in his body when not engaging in combat. This made it quite challenging for others to discern his true strength.
Furthermore, Chang Li's desire for immediate gains and losses caused him to underestimate Shi Feiyu's abilities. A person capable of hunting down second-grade mythical beasts was not someone to be trifled with easily. Once he initiated a fight, the Natural Source Qi within Shi Feiyu's limbs and body would explode. This instantaneous burst of energy was even more formidable than that of cultivators who condensed their Natural Source Qi in their dantian.
The moment Chang Li's fist struck Shi Feiyu, he felt a tremendous aura surging from within Shi Feiyu's body. Startled, he quickly backed away. But Shi Feiyu's actions exceeded his expectations by far. Even before Chang Li had fully retreated, Shi Feiyu's hands seized both his arms and pressed them downward.
