Open the wooden box and take out twenty small copper boxes from it, each copper box is inches square, take out one and say to Mr. Bai: "Old man, it is late spring now, the weather will get hotter and hotter in the future, people will inevitably have a heat stroke and headache brain fever, this medicine is called 'Wanjin Oil', which is made according to the secret recipe left by the ancestors." In the hot weather of summer, some people will suffer from heat stroke, you only need to apply this ointment to some important acupuncture points, such as Yintang, Renzhong, temples, you can wake up the mind and refresh your mind, and it is extremely suitable for getting rid of nausea, chest tightness, dizziness and other heat stroke symptoms .......". Bai Chuanli was a little suspicious when he heard Xiao Zheng's flickering, so he took the small copper box. "Don't believe it, old man, you are also an expert in medicine, you can try it yourself first", said Xiao Zheng and opened the copper box.

Bai Chuanli took a little white ointment in the copper box, put it under his nose and sniffed it first. I felt a cool breath rushing down my nostrils and into my brain, and my spirit was unconsciously lifted. Under Xiao Zheng's prompting, he wiped some on his temples and closed his eyes without speaking, and after a while, he opened his eyes and said to everyone: "The old man has been practicing medicine for decades, and he is somewhat famous in this Chang'an City, but it is rare to have a medicine like this that can eliminate and cure heat stroke so quickly, good medicine!" Seeing Bai Chuanli praise him so much, Xiao Zheng's heart suddenly had a bottom. Bai Chuanli then said: "There are menthol, camphor, eucalyptus oil, clove oil in this medicine, and the rest of the medicines, how to mix and how to make them, the old man can't guess."

Xiao Zheng gave the old man a thumbs up and said: "The old man is insightful, this medicine has two other advantages, that is, it can be used to prevent mosquitoes and insects, and in summer, it can be applied to the exposed skin in summer to have a strong repelling effect on mosquitoes, and you can sleep peacefully without being bitten by mosquitoes." In addition, the effect on common minor injuries and minor diseases such as dizziness, migraine, and not serious colds is quite good, but this medicine also has disadvantages, headache treatment, foot pain treatment, treatment of the symptoms but not the root cause, but it also works."

Mr. Bai nodded and waved his hand and said: "Your child is also a real person, it doesn't hurt to treat the symptoms but not the root cause, this medicine is made into a paste that can be carried at any time, it is extremely convenient to use, this medicine is enough to treat heat stroke with such a miraculous effect, and this medicine is suitable for all ages, if there is a serious illness, this medicine can be used as an auxiliary medicine, and then the main decoction can get twice the result with half the effort", the old man's eyes are poisonous, and he can see the benefits of this medicine at a glance.

Xiao Zheng smiled and said to Bai Chuanli: "Mr. Bai, the junior just came here to ask the old man to sell this kind of medicine, can Mr. Bai agree?" I saw Bai Chuanli twisting his beard and said with a smile: "In the past, the old man heard that your master and apprentice cured my nephew's illness, thinking that you just happened to be lucky, but now I am fortunate to see such a secret medicine taken by the old man, and the master is really a master in the hidden world, and the old man of this medicine will sell it on his behalf."

Xiao Zheng was also very happy to see Mr. Bai nodding, and several people divided the shares: Bai Chuanli, Zhou Bingrui and Xiao Hai each accounted for 20%, and Xiao Zheng accounted for 40%. Mr. Bai asked the man to take out the paper and pen, and Xiao Zheng began to write the paperwork on the counter. After writing nearly a dozen lines, he was stopped by Mr. Bai, only to see the old gentleman holding the document that Xiao Zheng had written half and said: "Last time my nephew sent an iron stove over, and the copper seal of this iron stove also has the words 'Yu Ji', this kind of font has never been seen by the old man before, and today I see the document you wrote The old man finally found the deity who wrote this word." The old man looks at your words like arranging troops. Righteous and awe-inspiring is a good hand, but between the lines of your words, what does it mean that these tadpoles are shaped and circled? Xiao Zheng smiled and explained to the old man that this was used to break sentences, just for fear of ambiguity when reading the document. Mr. Bai looked at the document and thought for a while, and said to Xiao Zheng: "Boy, the old man doesn't dare to say anything else, just rely on your handwriting and what kind of punctuation marks you have, and then look at the one in the document you drafted so clearly, the old man dares to say that you are famous in Chang'an City, it is a matter of day and night, and he will become a great weapon in the future."

When Xiao Zheng was about to finish writing the paper, Bai Chuanli said to Xiao Zheng and Zhou Bingrui: "The old man has something to ask for, if you can do the old man's two percent of the shares, the old man will give this share to the two of you." Looking at the puzzled eyes of the two, Bai Chuanli sighed and said: "The old man has only two daughters in his life, although there are many children in the two elder brothers' families, but they have mediocre qualifications, and it is difficult for them to enter the eyes of the old man, which is why the old man has no stepchildren, I am sixty and five this year, and after the old man is a hundred years old, I will just give more money to the younger generations of grandmen and daughters." But the most reassuring thing is the medicine hall created by this old man with his life's work, and the old man's biggest worry is that there is no successor to the medicine hall."

Mr. Bai said to Xiao Zheng: "As soon as you arrived here today, the old man felt that you had a fate in these medicine halls, in terms of medical skills, after you are a famous teacher, your old doctor also understood the medical skills just now; In terms of wit, if you test the old man's means, you will know that your kid has a lot of bad intentions; In terms of character, my nephew also said about your character, and with his shrewd eye, I believe that he will not look at the wrong person. If you are going to inherit this medicine hall in the future, the old man will not take a penny, and he will give this medicine hall to you, the old man does not want the name of your master and apprentice, as long as this medicine hall is opened, the old man's wish is enough", after finishing speaking, Mr. Bai looked at a few people with some sadness.

Xiao Zheng got up solemnly after hearing the sermon, and respectfully bowed to Bai Chuanli and said: "Back then, the first teacher and the younger generation were the village doctors who were used to the days of idle clouds and wild cranes, and now when they met for the first time, the old gentleman entrusted his life's work to the boy, if the boy did not accept it, would he not live up to the good intentions of the gentleman's life, but you look at this, you are now in good health, you will first run it in your hands, and when you are short of energy one day, tell the boy, the boy will naturally come over to help you take care of this medicine hall", after speaking, under the gaze of everyone, This article has been added as an article of the instrument.

Bai Chuanli was overjoyed when he saw Xiao Zheng write this clause into the paperwork, and the old man was extremely happy after the four of them signed and drew the charge, and asked the guy to go to the restaurant outside to buy some exquisite wine and food, during the meal, the old man watched Xiao Zheng keep drinking and liked it more and more, and when he saw that the wine was not enough, he asked the guy to run out and buy a few jars back, and the old man looked at Xiao Zheng and said happily Anyway, this shop is yours sooner or later, see that your handwriting is so good, it is better for you to write a plaque and hang it at the door, Xiao Zheng said to the old man after listening to the order, Let the guy go and buy a big brush, put the paper only on the counter, study the ink pen and write down the three big characters of "Yishitang", the upper left corner is still two words Bai Ji, and write the time in the lower right corner, after writing to the crowd said: "This word is to take the meaning of 'one treatment equally'", the reason why you still use "Bai Ji" on the left is to tell Mr. Bai that you will be a kid to take care of this shop in the future, and you will continue to use your name", seeing Xiao Zheng so sensible made Mr. Bai very moved, Bai Chuanli lowered his head and looked at the words on the paper, and said in a voice: "Good words!" Good meaning! Not only Bai Chuanli was amazed, but even Zhou Bingrui, who was coarse and literate, and Xiao Hai, who couldn't read big characters, all felt a majestic atmosphere on the paper.

Seeing that the sun was in the west, Xiao Zheng was worried about Xiao's mother and Jin'er at home, so he said goodbye to Mr. Bai, Zhou Bingrui didn't go back with the two because he wanted to stay with his uncle for two more days, Mr. Bai is also a happy person, and he saw that the two were going to leave without staying and sending them out of the store. As soon as the two of them got out of the street, two horses suddenly rushed out of the oblique thorn, one of which almost collided with Xiao Zheng, but fortunately, Xiao Haiyan quickly grabbed the reins of Xiao Zheng's mount, or he took Xiao Zheng's raw hand off the horse, and when the person on the horse strangled the horse and saw Xiao Zheng, he suddenly shouted: "It's you!" ”。
