The Strongest Black-Hearted Shop Owner

Yang Tian, ​​a college student who was just waiting to die, was reborn in Tianyu Continent by an accident. "System, how much does this Nine Heavens Dragon Slaying Knife cost?" Yang Tian said lightly. "Not much, 50% off for the host, 10,000 low-grade spiritual stones!" The system said calmly in a cold voice. Yang Tian twitched the corner of his mouth, a trace of rage flashed in his eyes, and he immediately took off the Nine Heavens Dragon Slaying Knife from the stand and threw it into the cesspool. "Wait a minute, brother, I don't want money, I don't want money..." The system suddenly panicked when it looked at him, and dared to say hurriedly. Yang Tian paused, a hint of appreciation flashed in his eyes, and then walked back. This is the story of an unscrupulous system and an unusually cold host.
