This sentence made Xiao Zheng angry, looked at this handsome young man and said: "Little brother, I wore a night coat in the middle of the night to seek medical treatment, I think you are not lightly ill."

Xiao Hai kicked the young man on the leg behind him and said, "If it weren't for the fact that you don't look like a thief, you would have been abolished a long time ago, you were so full that you were uncomfortable and put these broken iron pieces in your pockets, tell me quickly, what are you here for?!" How do you know that the young man still stiffened his neck and said: "I came to seek medical treatment, but I want to come by the way to see how you make this hundred steel, and the result is like this, I knew that I wouldn't come, really!" ”

Xiao Zheng looked at the young man without speaking, and when he stopped talking, he took out a small paper bag from his arms, opened it and had a black pill the size of a soybean in it, and asked Xue Rengui to break his mouth open, regardless of the young man's struggle, the pill went into his stomach, and after a while, let people untie the rope.

Seeing the confusion on the young man's face, Xiao Zheng said to him with a smile: "The medicine I just fed you is called 'Eroding Intestine and Brain Rotting Pill', you know me, I must also know my medical skills, there are a few worm eggs in this pill, and they will begin to grow after they reach your stomach and intestines, and they will start to eat your intestines slowly, and then they will crawl down your veins to your head and suck your brains, at this time you may crawl on the ground like a dog, and maybe you will also eat." It's also possible that you won't be able to move your whole body, and your face will become like tree bark, and when the insects eat up the flesh in your body, then it will explode with a bang, and of course you won't die until it explodes. The medicine I gave you won't flare up for three days, so you should go back and find your master, and after three days, you won't have to look for me."

After listening to Xiao Zheng's words, the young man's face was distorted with fright, his teeth clattered, and he said with a sigh of relief: "You, you, you are talking nonsense!" Xiao Zheng looked at him and said happily: "Okay, even if I talk nonsense, do you feel a kind of ant-like pain in your stomach now, hurry up and go to your master, it's really incurable." The young man covered his stomach in a cold sweat, looked at Xiao Zheng with fear in his eyes, and said hoarsely: "You are so ruthless!" With that, he turned and jumped onto the wall and disappeared into the night.

Seeing that this young man was gone, Xiao Hai looked at Xiao Zheng with some fear and said, "Brother, is there really such a terrifying poison in this world?" ”

"There's a fart! That's a fire-venting pill I just made today, and my stomach hurts for a while after eating it, and I'm fine after going to the toilet twice, do you want to take one too? ”

"Don't! Brother, I'm not so angry, but you also play this trick badly enough, and you are clever enough", Xiao Hai was also frightened by Xiao Zheng's words.

The next day, Xiao Zheng was giving lessons to the children, and an ox cart with a shed came from outside the courtyard gate, and the young man who was caught yesterday and a middle-aged man in his forties entered the courtyard with gifts. Today, the young man changed his outfit, his black hair was tied with a cyan cloth belt at will, he was dressed in a cyan cloth shirt, his eyebrows were long and sideburns, his slender and gentle eyes, his nose bridge was straight, and his fair skin was not inferior to Jin'er. The smooth and fair face smiled but showed a bad feeling, but it made people look comfortable from the bottom of their hearts, and the cold wind blew the ponytail on his head, adding a touch of unruliness to his sunny handsomeness.

Jin'er was a little daze when she saw this young man, her eyes were full of stars, Xiao Zheng coughed several times before calling Jin'er's soul back, turned around and glanced at Xiao Zheng and said, "It's much better looking than you!" Xiao Zheng was so angry that he glared at her.

The two came in and put down the gifts, turned around again, and the middle-aged man got into the car and picked up an old man with gray hair out of the carport, and the young man pushed a wooden chair out of the back of the car, exactly like the wheelchair of the offspring, and the old man was pushed into the yard while sitting on the chair.

I saw that the old man sitting in the chair was over sixty years old, but his eyes were extremely clear, but there were not many wrinkles on his face.

The young man was probably scared enough last night, and after seeing Xiao Zheng, he instinctively covered his stomach and shrunk his neck to hide behind the middle-aged man. The old man sat in a wheelchair and said to Xiao Zheng: "Mr. Xiao, the little grandson is stubborn, please Haihan for the inconvenience caused to you these days", after speaking, the old man also smiled at Xiao Zheng with eyebrows, quite like an old child.

Seeing that the old man was so funny, Xiao Zheng said with a smile: "Old man, it's okay, I'm just curious how you understand the kid's situation so clearly?" At this time, I saw the middle-aged man pushing the chair take out a letter from his arms and hand it to Xiao Zheng, opened it and saw that it was written by Sun Simiao to himself, to the effect that the old man's leg disease seems to be only solved by the operation you once said, and the handwriting is also written by Sun Daochang, and the letter cannot be fake, because he has never said the word surgery to others.

After Xiao Zheng finished reading the letter, the old man pointed to the two people next to him and said: "These two are the children and grandchildren of the old man. Mr. Xiao's exquisite production of farm tools made me greatly impressed, seemingly simple farm tools, but it contains iron control, wood, arithmetic and other aspects of the university, can make these exquisite farm tools out of all are great wisdom, just the old man has a leg illness to talk to Sun Daochang about this matter, listen to Sun Daochang said that these farm tools are made by you, the old man also has to ask you for this disease, .......".

The old man has a lot of knowledge, but he talks endlessly, making people unable to interject, and the middle-aged man on the side does not dare to speak because of the etiquette, only the young man last night, one will look up at the sky, one will look down at the ground, looking at the old man is also in a hurry to interject himself, listening to what the old man said, Xiao Zheng felt more and more that the three people who came were not simple.

Taking advantage of the old man's pause, Xiao Zheng hurriedly interjected, "Old man Gaojian, you have been talking for so long, can you tell the boy your tuba, the three of you have been talking in this courtyard for a long time, you have to go to the house to sit down and drink saliva, rest and let me diagnose your pulse, and let the kid enter the friendship of the landlord."

The old man looked at Xiao Zheng and said with some displeasure: "You baby, what are you anxious about, you have to let the old man finish his words, okay, the old man loses, this is the old man's son loses Hui, and the one you caught last night is the old man's grandson." I'm not a loser in this iron line, and it's not the old man's interest, I just wanted to come and visit you directly and ask at the beginning, but this kid is too curious, he wants to see everything, and there is no malice in the first place, and now he has planted a big heel in you."

"It turned out to be Luban, old man, disrespectful, disrespectful! Please forgive me for the offense of the juniors last night", Xiao Zheng looked at the three people and laughed in his heart, he caught such a big fish with one pill, and then said: "It's okay, let this kid suffer a loss, and let him have a long memory."

At this time, the male loss Ruoyi in the back said a little anxiously: "Grandpa, your old man will help me ask him for an antidote, if there is no antidote tomorrow, you will be cut off from your grandchildren", Jin'er laughed out loud when she heard the young man say this.

The old man blew his beard and glared at the public and said to Ruoyi: "You idiot! Boasting of being smart all day long, I don't think I'm used to you, like Mr. Xiao, a person who can take out such a delicate farm tool to benefit the world, and give medicine in these villages, he will use this kind of subordinate means to deal with you, really! It's nothing more than scaring you and making you grow your brain! Stay and go! ”。

The old guy's eyes are poisonous, and he saw through Xiao Zheng's methods at once. After finishing speaking, he turned his head to Xiao Zheng and said: "Last night's incident, my son has been watching from behind, and the old man has told him that as long as he can't die, leave him alone, and let him know that there are people outside the world, and there is a sky outside the sky." Xiao Zheng felt a chill behind him after hearing this, and these old rivers and lakes are still much more tender than himself, the praying mantis catches cicadas, and the yellow finch has forgotten the truth behind him.

Looking at this incomparably handsome Gong Ruoyi, Xiao Zheng smiled evilly and said: "Yesterday, I saw that you were too angry, and I gave you a pill to make you diarrhea, and when you have no strength to turn your legs and stomach, you won't pick up other people's walls."

Gong Yi Ruoyi angrily pointed at Xiao Zheng and couldn't say a word, Gong Yi Hui, who had not spoken, looked at Xiao Zheng, and then looked at his son and shook his head with a wry smile.

Helping the male to the kang, the trouser of the left leg faded above the knee, and seeing that the old man's knee was swollen, he concentrated on touching the tissues around the knee, and gently pressed the lesion.

When asked about the medical history, the public lost the plantar said that a few years ago it was only after the winter pain, Sun Daochang gave some decoction to take the medicine and can still walk, this year in the winter, maybe the body bones are not good or I don't know what's going on, the knee is swollen all of a sudden, and the pain at night can't stand it, find Mr. Sun, but Mr. Sun said that he wants to use a knife to cut off the things inside, but Mr. Sun said that you are the first person in the world who can use a knife, so he threw the old man to you, originally Sun Daochang also wanted to come with me, Look at how you perform this surgical technique, and then Sun Daochang didn't come when he had a patient to be treated.

"Boy, the old man is counting on you on this leg," said the man, stroking his beard. Taking advantage of the time to speak, Xiao Zheng finished diagnosing his pulse again, and after the comprehensive examination, Xiao Zheng had a bottom in his heart, the old man had a bone spur on the calf bone under the knee and a bone spur on his head, and it was on the surface of the bone, and it was a simple operation in the later generations, but it was still to be treated with great caution in the Tang Dynasty.

Xiao Zheng looked at the public and asked, "Old man, is your family rich?" The old man was stunned for a while, and said with a smile: "Boy, it depends on what you say, if you can really cure the old man's leg, the old man will take you to prostitute all the courtesans in Chang'an City, and the old man can still afford the money."
