After Transforming into a Toad, I Worked Hard to Become an Immortal

I'm wearing a book. Dressed as a toad in a novel about sadomasochism and deep spiritual cultivation. His appearance does not last more than three sentences. Because the heroine is going to use the gallbladder of a big snake to make elixirs, she asks the hero to find something to make a trap to lure out the big snake. The original body was just passing by while jumping around looking for mosquitoes to eat, and was stared at by the male protagonist. In a matter of seconds, the original body quaked, and the male protagonist presented his body to the female protagonist, and then was sent into the stomach of the big snake. But it doesn't matter, I will take action. Work hard to become an immortal and take revenge.
