I Asked You to Be a Snake Catcher and You Became a Dragon Slayer.

Lin Mu traveled to a dangerous world infested with snakes. Evil snakes bring disaster, evil dragons bite people, and snakes are like ghosts seeking life. The snake-taking system is being implanted, giving the host a body that is invulnerable to all poisons and can absorb snake venom to gain attribute points. From this moment on, a snake catcher appears looking for a snake bite. Others catch snakes for fear of accidentally being poisoned and dying. Lin Mu looked for the most terrifying strange snake in the world, and then stretched out his arm with a smile. "I heard that you are called the underworld snake. One bite is equivalent to stepping on the road to underworld. Come and bite me." "What, one drop of your snake venom can kill a million people instantly, let me have a taste." "You are very fierce, aren't you? Because you sealed a mountain, you can be my pet." One day, a vicious snake turned into a dragon and was about to kill it. Lin Mu appeared and slapped him to death. I'm not a snake catcher, please call me a dragon slayer. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
