Xu Yi just saw a clue, this kid had a cold.

It should not stop breathing and suddenly die, and the problem must have another clue.

"What did this kid just eat?" Xu Yi asked.

Zhang's shopkeeper's wife couldn't stop crying and replied hesitantly.

"I ate rice just now, and today's rice is a little hard."

Hearing this, Xu Yi immediately had a chain reaction in his mind, and he thought of the problem.

The cough caused by the wind chill caused the rice in the mouth to be inhaled into the trachea, and the child's trachea was small and directly blocked inside, which led to respiratory obstruction, suffocation and hypoxia, and the child fell into a state of suspended animation.

As a traditional Chinese medicine practitioner, Zheng Qi has no way to make modern first aid measures in the face of this situation, and can only give incurable results.

At this time, Xu Yi felt the burden of another human life, which was pressed on his body.

In an instant, Xu Yi called Lao Bai.

"Lao Bai, how to deal with children's respiratory tract inhalation of rice grains?"

Lao Bai said helplessly: "You also have to take care of such a trivial matter?" ”

"Let's not be in a hurry now, it's okay to take care of some small things, don't talk nonsense, Lao Bai!"

"Okay, found it! Abdominal Pounding Method! Wrap your hands around the patient's abdomen and squeeze back and forth to let the abdominal gas rush into the trachea, forcing the gas through the trachea and flushing out the foreign body! ”

Xu Yi said to do it, and immediately hugged the teenage child in front of him from the back, and pressed the child's abdomen with his arm, so that the child's abdominal gas continued to converge to the trachea.

Poof~.

A mouthful of bloodshot foam squirted out of the child's mouth, mixed with a few grains of rice.

These grains of rice are the culprits that make the child suffocate.

"Zheng Qi, his wind and cold are not well yet, you help him massage, drink some water, and give him a Yinqiao pill by the way."

Zheng Qi replied and helped the child who had woken up to massage his chest, and on the other side, the child's mother also brought a bowl of water to help the child take the Yinqiao pill brought by Zheng Qi.

Just put the water on the child and gave the child Yinqiao Pill, and the child's face immediately looked much better. Perhaps it was a psychological effect, and the child quickly fell asleep.

The shopkeeper Zhang watched the child fake his death, and he didn't dare to breathe, and he didn't dare to breathe until the two "Langzhong" finally gave the child back.

"Two, kid this... Is it saved? Shopkeeper Zhang's voice was full of trembling.

Zheng Qi nodded while taking the pulse of the child, which was regarded as acquiescing to the words of the shopkeeper Zhang.

After another slight pause, Zheng Qi breathed a sigh of relief.

"This child suffers from wind and cold, and after taking Yinqiao pills, everything will be fine when the child wakes up."

Hearing this, Shopkeeper Zhang excitedly knelt down for the two of them.

"Two gentlemen, this is forty-two taels and six coins of silver, which is all the money in the account of the small shop, please accept it to repay the kindness of the two of you to my son!"

Seeing this money, Xu Yi and Astragalus glanced at each other.

"Lao Zheng, you should keep this money, after all, I still owe you money."

Zheng Qi glanced at Xu Yi resentfully, "I barely earn twenty or thirty taels a year, except for food and drink, I have to earn it in ten lifetimes..... And you're now... He owes me a thousand taels. ”

Xu Yi smiled and said, "Transaction, equivalent exchange." I'll give you a thousand taels, and you'll have to be ready for your price. ”

Zheng Qi nodded solemnly, and quietly took the forty-two taels and six coins of silver from the confused shopkeeper Zhang.

When the shopkeeper saw the two people guessing the riddle at this time, he was confused for a while, and he couldn't help but secretly say in his heart.

"These two people are really not ashamed, I will let them, they really take all the money...... Two guys are so annoying.... But for the sake of the son.... Give them the money. ”

Shopkeeper Zhang settled the family, and then took the two to the living room at home.

"The two of you, the medicine used by Zheng Lang just now to treat wind and cold can be described as magical. Do you want to make a lot of money through this Yinqiao Pill? Shopkeeper Zhang said solemnly.

Xu Yi almost laughed out loud when he heard Shopkeeper Zhang say this seriously.

It seems that Shopkeeper Zhang has the ghost idea of Yinqiao Pill, and wants to make a lot of money from Xu Yi and Zheng Qi, and earn back the money he handed over just now.

Zheng Qi and Xu Yi glanced at each other, and they both saw a trace of cunning "business opportunities" in each other's eyes.

"Ahem, as the creator of Yinqiao Pill, I, Xu Yi, want to negotiate a deal with you." Xu Yi said with a smile on his face.

"Xu Langzhong... Oh, shopkeeper Xu. As long as you can act as an agent for Yinqiao Pills, you can mention what you want. The shopkeeper was smiling all over his face, he really wanted to talk about this business in order to recover the loss just now.

"Ahem, in fact, we can give you the power of agency, but there are two requirements." Xu Yi said indifferently.

"Two requests? Which two? ”

"It's very simple, this Yinqiao Pill can't be sold in Huating County, it can only be sold in the countryside." Xu Yi put forward his first request.

"This.... OK. Shopkeeper Zhang hesitated, and immediately accepted it, if you can't sell it in Huating County, you can't sell it in Huating County, the water in Huating County is too deep, and you can make a lot of money by selling points in the suburbs.

"The second one, adults can cure all the wind and cold by taking ten pills, and my second condition is that each pill cannot exceed 20 yuan, and each person can sell them a maximum of 20 pills. Is this acceptable to you? ”

Xu Yi put forward the second condition, which is still very important and related to Xu Yi's next plan.

"And how much stock do you have?"

"I can give you 10,000 Yinqiao pills, and you can earn a lot of money, at least one hundred taels." Xu Yi threw out a tempting condition.

"That can be done!" Shopkeeper Zhang summed it up in his heart, thinking that this order could earn at least a hundred taels of silver, and he could still make a lot of money.

"Shopkeeper Xu, Zheng Langzhong, you two can rest assured. I have more than 20 men under my hand, and they are very diligent in their work, and it only takes two days to sell them out for you. ”

"That's good, shopkeeper Xu, this is a thousand, we will supply a thousand a day in the future, I hope the cooperation is happy!"

Xu Yi handed the Yinqiao Pill with more than a thousand packed into a box to Shopkeeper Zhang, and carefully advised.

"Shopkeeper Zhang, where's our deposit?" Xu Yi reminded again.

When the shopkeeper heard the word deposit, he couldn't help but wave his pen and gave his house to Xu Yi, and the discount was forty taels of silver.

The sale was settled, and Xu Yi and the others didn't have to stay here, so they left the hotel.

"Xu Yi, could it be that this Yinqiao Pill, you just contracted it out forever?" Zheng Qi was puzzled.

"Hehe, how is that possible? I have great wisdom. Do you still have the Silver Warp Pill on you? Xu Yi asked with a smile.

"Oh, the Yinqiao Pill is gone, but there are still two pieces of paper wrapped in pills, which I gave to the child just now, and I haven't had time to throw them away." Speaking of this, Xu Yi's smile became more playful, and Zheng Qi felt a little hairy in his heart.

"Xu Yi, why are you smiling so weirdly?"

"Look at what's written on the paper?"

"Oh, I'll see."

Zheng Qi took out the paper ball and opened it to take a look.

[If you want to buy this medicine, please go to the Zheng's Medical Center, thirteen miles southeast of Huating County. 】

"This...."Zheng Qi was a little incomprehensible, this medicine has been sold, why did he leave a note.

"Lao Zheng, you still can't turn your brain. The more this shopkeeper helps us sell. Will more people know about us soon? ”

"Let's call it grafting this time!"
