Three days later, in a simple thatched hut, a kind old man finally showed a smile on his weather-beaten face as he looked at the seriously injured boy lying on the bed. Just three days ago, the old man accidentally spotted the child while passing through a valley while collecting medicine. Covered in tattered clothes and covered in blood, when he carefully confirmed that the boy still had a faint breath, he immediately used his clever medical skills to rescue the boy and take the boy back to the hut where he lived to take care of him. Now that the old man was sure that the boy was out of danger of death, he breathed a sigh of relief and smiled.

Wang Yan had a dream in which he was wandering around alone in the dark night, thunder rumbling in the sky, and terrifying electric snakes flickering in the air from time to time. Suddenly, a bolt of lightning struck him hard, and he was in pain.

The pain was so clear, every part of his body was hurting, and Wang Yan couldn't help but moan in pain. The old man, who was boiling medicine outside the hut, heard Wang Yan's moaning, hurriedly walked into the house, came to Wang Yan's side and whispered, "Child, are you awake?"

Hearing someone speak, Wang Yan tried hard to open his eyes, and what caught his eye was an old man's slightly emaciated face with a kind smile. I saw that the old man's hair and beard were gray, his big eyes were bright, his nose was high, and his mouth was covered by his beard.

"Grandpa, where am I? Am I already dead?" remembering the scene when he rolled down the slope, Wang Yan felt that he must be dead, this is another world.

"Huh. The old man smiled and said, "Silly boy, how can you talk when you die? This is my home, your body is very weak now, and some serious injuries in your body will not be healed for a while, don't talk anymore, if your body hurts, just bear with it, but don't move, wait until you heal from your injuries." The old man gently wiped away the sweat oozing from the pain on Wang Yan's face, and then said, "I'll go and see if the medicine is boiled first, since you are awake, I should feed you the medicine, so that your injuries can heal faster." With that, the old man turned and walked out of the hut.

Seeing that the old man had gone out, Wang Yan began to look at the hut. The hut was not large, but there was a window on one side, and many dried plants hung beside it, and two large gourds were placed on the ground, and at the door there was a large basket made of branches, and a few tools of unknown purpose were scattered around the basket. Wang Yan found that his wood-chopping axe was also mixed with those tools, and he remembered that he had lost the axe in the process of rolling down the slope, thinking that the old man not only saved himself, but also carefully retrieved his lost axe. There was nothing else in the hut except for the simple bed made of a few planks where he was now lying.

Wang Yan felt that his body began to ache again, and he didn't dare to move, so he had to clench his teeth and try to endure it. Because the old man had instructed him not to move.

The door of the thatched hut was gently pushed open, and the old man walked in with a bowl full of medicine, sat down beside Wang Yan, took out a wooden spoon, scooped the medicine, blew it with his mouth, and tried that the temperature was right, before sending the wooden spoon to Wang Yan's mouth and feeding him the medicine. Spoonful after spoonful, until the medicine in the bowl was drunk, he said to Wang Yan: "Child, you have a good rest, no one here will disturb you, rest assured to sleep." I still have to go out to collect medicine and not come back until the evening. Wang Yan listened, nodded, and said that he understood.

As the days passed, Wang Yan quietly recuperated under the careful care of the old man. In order to let Wang Yan recuperate with peace of mind, the two rarely talked to each other, because the old man knew that Wang Yan must have a sad story, otherwise how could such a young child enter this forest alone? During this period, the old man only told Wang Yan that his surname was Tao, and asked Wang Yan to call him Grandpa Tao, and the rest was to ask Wang Yan about the recovery of his body, so as to decide the situation of the medication, so that his body could recover as soon as possible.

A month later, Wang Yan's injuries were all healed.

"Yan'er, come here. Grandpa Tao sat outside the hut and said to Wang Yan in the house. "Here, Grandpa Tao. Wang Yan was wearing clean clothes, his little face was red because of the nourishment of herbs, and the whole person looked very energetic, and sat down next to the old man: "Grandpa Tao, what's wrong? Aren't you going to collect medicine on weekdays? Why don't you go today?" "Grandpa is not going today, I want to hear Yan'er's story, can you tell grandpa, why did you come to this forest alone and get injured?"

Hearing Grandpa Tao's question, Wang Yan fell silent. In the past month, Wang Yan has forced himself not to think about the past. Grandpa Tao took care of him so carefully that he felt warmth that he had never felt before, and he had long regarded Grandpa Tao as his own grandfather.

"Grandpa Tao, if I tell you, will you not want me anymore?" Wang Yan asked with some fear. "Why don't you want you?" Grandpa Tao frowned and asked Wang Yan. "Because I killed my own mother as soon as I was born, and I also injured the child born to my father and stepmother, and my father said that I was a demon...... "Wang Yan began to tell the story, he told his life over the years.

Grandpa Tao burst into tears after hearing this, and hugged Wang Yan: "Child, that's not your fault." You can only blame your father and stepmother for being too ruthless. If you don't dislike it, follow Grandpa to live here. Grandpa is old, and he can teach you medical skills, are you willing to learn?"

"I do. Wang Yan put his arms around Grandpa Tao's neck and was very happy: "Great, grandpa......"

The next day, as soon as the morning dawned, Wang Yan carried the medicine basket, took the tools, and followed Grandpa Tao to learn the skills of collecting medicine. "There are herbs everywhere in this forest, and you have to discern them carefully. The branches and leaves of some plants are medicines, the roots of some plants are medicines, the flowers of some plants are medicines, and the internal organs of some animals can also be used as medicines. Among them, you must distinguish poisonous herbs from poison to avoid poisoning after accidental ingestion and misuse. Grandpa Tao admonished. "Grandpa Tao, don't worry, I will definitely keep in mind every word you taught me." Wang Yan humbly accepted Grandpa Tao's teachings.

"Look over there. Wang Yan looked in the direction of Grandpa Tao's finger and saw many plants growing in a meadow.
