I'm Invincible Thanks to My Guarantee

Play a little game and travel through time? No one else has a guarantee? My guarantee seems to come up with whatever I can think of. "Dig trough, what is a five-star alien beast?" Passerby A. "Can these five stars be summoned directly?" Passerby B. "I feel like a waste." The former world's strongest man. "What, how did I draw the five-star alien beast? I have a guarantee. After thirty draws, there will be a golden legend!" Qin Ou said as he looked at the strong men below who asked him how to draw the five-star alien beast. "What's the guarantee?" A group of strong men felt that life was boring. This is a story in which only the protagonist has a guaranteed function, and he is invincible in a parallel world by relying on the guaranteed function.
