Children are in the woods, in the direction of the most dense trees, left and right. After a while, they passed through the dense forest, came to the bottom of a waterfall, and passed through the waterfall, and under the waterfall was an extremely wide cave, wide inside and small outside. At first, only one person was allowed to enter and exit, but after a few steps, the cave became wider and wider. The hole is very deep, flat and entering, the road is accessible in all directions, the more inside, the more its hole opening, if you are not familiar with this hole, you will inevitably get lost in the hole, you can't find the exit. It's sparsely populated, and no one has ever been here. Not to mention that some people have discovered that there will be such a world under the waterfall.

Children have been living here for ten years, and they are no longer familiar with this cave. The cave is darker and darker the further it goes, but it is unhindered for children, and after living in the cave for a long time, they will naturally develop the ability to see things in the dark. But I saw him turn left and right, and after a while, he came to the end. At the end is a large circular cave hall, which can accommodate more than a hundred people. There is a round hole on the top of the cave, and the round hole leads straight out, and the light shines through the round hole, which just illuminates the hole. The cave is filled with all kinds of medicinal herbs. The child walked around the place where the medicinal herbs were stacked, but saw an alchemy furnace that was burning brightly. Sitting by the fireside sat an old man with a white beard, about sixty years of age, and extremely emaciated. At this time, it was autumn, and the weather had turned cold, but the old man's stove was burning extremely vigorously, and it was unusually hot by the stove. The old man held a fan in his left hand and fanned slowly. Eyes slightly closed. The demeanor is extremely leisurely.

Children are extremely naughty. Whispered behind the old man. I wanted to scare the old man. Before he stretched out his hand, the old man had already said, "Yun'er, you little ghost spirit spirit you want to scare grandpa again, don't you?" The child's name is Dugu Yun. It was an orphan raised by this old man. I discovered this cave ten years ago and lived in this cave.

Duguyun retracted his hands and said, "It's not fun at all, every time you demolish it, grandpa." The old man opened his eyes and said with a slight smile: "You kid, didn't you say that you went to collect medicine? The old man was very kind, smiled and said, "Lie and lie to grandpa again, right?"

Dugu Yun said: "It's true." I didn't lie to you this time. Duguyun sat on the old man's lap, hugged the old man's neck with both hands, and said, "Grandpa, I did a good deed today, do you believe it or not?" The old man stretched out his hand and hugged Duguyun into his arms and said, "Believe." Of course Grandpa believes in Yun'er. Dugu Yun: said: "Then grandpa guess, what kind of good thing is good?" The old man said: "It's better for Yun'er to tell grandpa, grandpa can't guess." Duguyun said: "It's boring, grandpa is like this every time, it's not fun." He said, "Forget it, let's tell Yun'er to grandpa." Yun'er was going to go up the mountain to collect medicine today, but when she got to the forest outside, she happened to bump into someone hanging herself, and Yun'er couldn't see death without helping, so Yun'er rescued the man. Grandpa, do you know why that man hanged himself?" the old man said, "Grandpa is not a fairy, how can he know." ”

Dugu Yun said: "Say it, grandpa, you must think it's funny." The old man said, "If you hang yourself, you will hang yourself, what is the interesting reason?" Grandpa wanted to know. Duguyun told the servant. But he laughed. Actually, it's not funny at all. It's only because Duguyun wants to introduce his grandfather into the circle that he pretends to be funny.

Sure enough, when the old man heard this, his face suddenly turned ugly. looked at Dugu Yun and said: "You saved him, have you promised others to treat people." Duguyun pretended to be strange and said: "Hey, I haven't finished talking now, how can grandpa guess it." The old man said, "Do you still need to guess this? With your child's temperament, you have almost finished learning your grandfather's skills." It's almost like actually healing people. Will you let go of such an opportunity?" Dugu Yun grinned and said, "It's still grandpa who knows Yun'er best." ”

The old man said: "Don't be too happy, although you have learned your grandfather's skills, but you are still young, but you have zero experience, and you also treat Zhu Fafu, that Zhu Fafu is not a good stubble, if you have a business trip, then you will get into trouble." Dugu Yun said: "Then what should I do?" The old man said: "In Grandpa's opinion, it's better not for you to go." Study in this cave for a few more years, and when Grandpa has passed everything on to you, then you can go outside and practice medicine and save people. Duguyun stood up and said, "Then how can I do it, I have promised that person." How can a manly man turn his ear on his ears? That's not a villain who doesn't believe in his word. The old man said, "You are only twelve years old." It's just a child, and adults won't take it seriously if it's a child, so how can it be regarded as a backlash. ”

Dugu Yun said: "No, grandpa's words are not right. But the character of mortals is not cultivated from childhood. Moreover, Yun'er studied medicine to treat people. If you don't save yourself when you see death, then what's the use of Yun'er studying medicine. Grandpa, what are you refining medicine in this cave all day long?" The old man's face suddenly turned blue and purple for a while. Because these words had pierced deep into his heart, and reminded him of how he didn't study medicine when he was young to treat people. The old man pondered for a moment. Duguyun looked at his grandfather and froze, feeling very uneasy, thinking: "Is it too heavy for me to speak, and I hurt my grandfather's heart." But when I thought about it, my grandfather had no skills, but he hid in this cave and didn't deal with outsiders. Isn't it a shame to be alive?

The old man thought about it for a long time, and his heart floated up the past, what a beautiful scenery he was in the past, he was respected as a living immortal by the world, and he didn't know how many lives he had saved with a pair of wonderful hands. But now, in order to avoid the pursuit of a powerful opponent, he has been hiding in this deep mountain for more than ten years. Ignore the outside world. Where does this come from? Thinking about it, the old man thought of the child in front of him. Duguyun was raised by him, and for more than ten years, Duguyun has become his only comfort.

The old man's face turned a little better, and he said, "Yun'er." No matter what you say, grandpa is suffering, and in short, grandpa will not agree to let you go to see a doctor. Dugu Yun said unwillingly: "Whether grandpa agrees or not, Yun'er is going to decide anyway." Grandpa, you can't stop Yun'er, no matter how you stop me, as long as there is a chance, Yun'er still has to go. At that time, Yun'er was afraid that she would not plan to come back as soon as she left. The old man didn't expect Duguyun to say such a thing. Looking at his resolute eyes, I knew that this kid had always done what he said. couldn't help but sigh: "You kid, grandpa really can't do anything about you." How about an agreement between our grandfather and grandson?"

Dugu Yun knew that his radical method had already worked, although he was happy in his heart, he didn't look happy at all, and asked, "What agreement?" The old man said: "The patient's grandfather can help you treat, but there is a condition, you have to stay with your grandfather in the future, and you can't leave your grandfather for at least five years." By the end of five years, you've learned all of your grandfather's skills. At that time, no one could bully you when you went outside. Grandpa is relieved, okay?" Duguyun knew that his grandfather was for his good, and his heart was very moved, hugging the old man and crying: "Grandpa, you are so good." It's all Yun'er's fault, which makes you sad. Grandpa rest assured, Yun'er will stay by his grandfather's side for the rest of his life and will never leave his grandfather. ”

The old man hugged Dugu Yun and said, "Silly child." But in his heart, he was secretly praying that he would not let his opponent know about this time he went out of the mountain.
