I Got the Wrong Script for the Arrival of God's Favor

You walk out the door and your dog turns into a three-headed hellhound. You watch the news and the Yamata-no-Orochi emerges from Mount Fuji, killing hundreds of thousands of people. You panic. But you are not afraid, because you have been reborn with countless experiences and history. You think you can cultivate the strongest beast, become the strongest beast master, pick up the most beautiful girl, and become the strongest man in the world. But while you were practicing the contract spell, a mosquito bit you. You killed it easily. Looking at the pool of blood in your hand, you panicked. It sucked your blood and inherited your bloodline. The contract was successful. Then... I'm still so panicked, I don't want to be born again.
