Sign a Contract with a Crocodile and Start Overthrowing the World

Qian Jitong had his limbs chopped off by a killer and thrown into an alley because of a video dug up by his friend. When he was about to die, a crocodile claiming to be a god appeared. The killer soon returned. For his own safety and the safety of his brother, Qian Jitong agreed to sign a contract with the crocodile at the cost of doing something big with it. "A big cause is a big cause. Anyway, I am in this situation because of the so-called big cause." Qian Jitong thought this way. What a good friend dug out is a video that can overthrow the entire world. How can it not be considered a big cause?
