If I'm Not Good at Killing, How Can I Get a Headshot with a Flying Needle?

Everyone knows that there is a wonderful doctor in Waiyuan, known as Mr. Green Hands, who can cure hundreds of poisons with a silver needle. But no one knows that this miracle doctor has been corroded by a strange poison for twenty years, and now he only has half a month left to live. No one knows that every time he takes action, he is risking his life. Only by finding spiritual stones and planting strange medicines can we continue our lives. When he tried to cure three strange poisons for the spirit stone, he found that all the poisoners came from one person's plan. He wanted to force Lin Yu to take action and treat people. Lin Yu sneered: "I have three conditions." "Why are you negotiating terms?" "The lives of everyone here, including you and me!"
