For a few months, Yang Yu has been thinking about the black child Shi San, if it weren't for the fact that the old man Gu Nian was now unsafe outside, and Yang Yu was strictly forbidden to go out, maybe Yang Yu would really run outside the valley to find Shi San!

Anyway, Yang Yu is still a child less than ten years old, and he has a great attraction to children of the same age when he is a child.

Now when he saw Shi San coming to find him, he was overjoyed, and immediately ran towards him, shouting, "Shi San, why are you here?"

Shi San stood still and didn't move, and when he saw Yang Yu come out, there seemed to be a tangled look in his eyes, but after a while, he gritted his teeth, turned over and bowed to Yang Yu, and said while kneeling: "Request...... Help!"

Shi San suddenly overwhelmed Yang Yu at this moment, this black boy Shi San didn't do anything himself? Why is he so grateful?"Help! Save what's life?Is he injured?" Thinking of this, Yang Yu was immediately shocked, ran to Shi San in three or two steps, and helped him up!

"Shi San, are you injured, where are the injuries?"

Shi San's body couldn't struggle, and he still said in his mouth: "Yang ...... Yang Yu help!"

"You get up first," Yang Yu said, "Tell me what's going on? What's wrong with you? Let me save you?"

"It's not to save me, it's ...... My father!" Shi San obviously didn't speak fluently, but Yang Yu finally understood, Shi San came to beg Yang Yu to save his father this time, but he didn't know what happened to his father?

"Shi San, don't worry, you come with me, let's go find the old man, you tell me slowly!" Yang Yu still dragged Shi San up.

Shi San spoke very concisely, it seemed that he usually spoke like this, what he meant, Yang Yu understood, Shi San depended on his father outside this valley, but a short time ago, his father was seriously ill, and he saw that his health was getting worse and worse, and now he was dying, at this time he remembered what his father told him.

That was after the last time he and Yang Yu fought the big wild boar, after going back, his father told him that he couldn't go in that valley, there were immortals living there, and the immortals had great abilities, maybe he would be angry because he broke in without permission! But Shi San didn't think that Yang Yu was an immortal, and when he met him, he couldn't even beat the big wild boar!

But then his father still strictly ordered him not to step into the valley, Shi San was very filial and obedient, so he never entered the valley again during this time, but this time he remembered his father's words, and thought that the immortals would definitely be able to cure his father's illness, so he didn't care so much in a hurry, and went straight to the valley to find Yang Yu.

Yang Yu took Shi San to see the old man, and when he passed by the entrance of the cave, the big black dog ran up, sniffed Shi San's hand, and his eyes flashed, but he didn't do anything, and still ran back to lie at the entrance of the cave.

The old man heard Yang Yu talk about Shi San last time, and now he has really seen this black child, he also has a little experience, logically speaking, it is impossible for outsiders to appear in this valley, Yang Yu is an exception, not to mention that there is another Shi San! The old man can see at a glance that Shi San's face, neck and body are covered with a kind of bark sap!

After Shi San saw the old man, his expression was very restrained, the old man should meet the definition of an immortal in his mind, so he was a little timid! Yang Yu told the old man on the side the reason why Shi San came over.

"Old man, Shi San's father is seriously ill now, don't you know how to use herbal medicine, can you go and save his father?" Yang Yu finally said.

The old man couldn't help but smile bitterly, he did know some herbs and knew some simple pharmacological changes, but he was not a doctor, otherwise he wouldn't have to raise his legs for so long.

However, he thought about it for a while, and had a plan again, so he went to prepare for it, and said to the two children: "Go, go and see the patient, see if it can be treated!"

Shi San saw that the old immortal in front of him was willing to go to see his father, and immediately knelt down and kowtowed excitedly: "Thank you,...... Old Immortal!"

"Get up quickly!" The old man hurriedly helped Shi San up: "I'm not a god, although I've lived for a long time, the master is gone, I'll do my best, I'm not a doctor, take me to see it first."

So Shi San led the way, and Yang Yu accompanied the old man out of the cave and walked out of the valley, followed by the big black dog.

The northeast corner of the valley basin is sparsely wooded, and out of here = less than two miles outward, there is a fence wall erected in a clearing, which is basically formed by the cutting of trees next to it, and the wooden house in the middle is obviously made of those books, although rough but very strong.

Yang Yu noticed that there was a black dirt bag type thing more than one person high outside this wooden house, and he didn't know what it was for, Shi San led the two into the wooden house!

The coals in the fire pit on the ground were almost extinguished, and the simple room was hardly furnished, and on one of the beds lay a tall man, covered with an animal skin, with a haggard look and a sallow face, and now his eyes were tightly closed.

Shi San stood there, something flashing in his eyes, but he asked his lips not to speak, and the old man stepped forward to check on the man's situation, this middle-aged man was obviously Shi San's father.

Shi San's father, his dying breath seemed to be very sick, but the old man found that a faint black gas on the sallow face of the middle-aged man was shrouded in the position from the top of his head to the center of his eyebrows, which was an obvious food poisoning phenomenon.

"Child!" the old man beckoned to Shi San and said, "Come here, let me ask you, has your father eaten anything bad recently?"

Shi San thought for a while and said: "Dad is in a hurry, because there is no prey during this time, I remember that the potato pieces he gave us last time can be eaten!" Shi San pointed at Yang Yu and said, "I'll dig some to eat, and I haven't eaten anything else!"

The old man seemed to understand something, and he asked Shi Sandao, "Do you still have those potato pieces you said?"

Shi San nodded, turned around and took out some plant rhizomes from the corner of the room!

The old man knew that it was wrong at a glance, Shi San didn't know that kind of yellow essence potato pieces, and he dug up the tubers of other plants by mistake, which was obvious food poisoning, and he said to Shi San: "Wrong, these things can't be eaten, your father is poisoned"

Shi San suddenly panicked, he understood what poisoning meant, his mother and two elder brothers died one after another because they couldn't find anything to eat, picking poisonous mushrooms in the forest, and now his father was also poisoned?

"Don't be afraid, don't worry, the old man can detoxify your father!" said the old man with a smile.
