If they were outside, dealing with a 7th level Earthly Core Realm cultivator would still be quite difficult for him. However, within this great desert, the essence qi of all cultivators was suppressed. In other words, the strength of the middle-aged man in yellow robes was at most equivalent to the 3rd or 4th level of Earthly Core Realm.
Under these circumstances, killing him was naturally as easy as turning over his hand.
Li Yun reached out and grasped the Mansa Flower in his palm. Then, he sat down cross-legged and began absorbing the flower's energy.
Under his absorption, the Mansa Flower swayed gently, and clusters of yellowish-brown light bloomed from its petals. The light scattered like flowers falling from the hands of a celestial maiden, then slowly merged into Li Yun's body.
