Seeing the old man's hand inching closer to Xiao Yifei's chest, while Xiao Yifei was still hanging in mid-air, held by his collar, just as the old man was about to touch the treasure map, his expression suddenly changed rapidly, from smugness to shock, and then to pain.
The old man suddenly knelt on the ground, clutching his chest, looking extremely uncomfortable. Xiao Yifei, freed from the old man's grasp, was not surprised at all upon witnessing this scene, because he was the cause of all this.
Indeed, when the old man tried to take the treasure map, Xiao Yifei secretly pulled out a Green-eyed Silver-tailed Needle from his pocket while the old man was distracted and shot it into the old man's chest with a technique.
But the old man's expression was not merely from being pricked by the needle; after struggling for a while, he suddenly spat out a black blood clot and began to cough violently. "What have you done?" the old man asked incredulously, looking at Xiao Yifei.
