Summer smoothies and cold drinks are just a spice for life, in the shocked eyes of Old Doctor Ge, Zhao Yuan lifted the lid of the basin tightly, and a cool air came to his face.

"This ...... This ......," Dr. Ge was completely shocked.

Could it be that Brother Zhao really knows how to be immortal, this big summer, he turned a basin of water into ice under his eyelids.

"Wow, Master Zhao, how did you do that?" Xiao Qi also asked in shock.

Maybe the amount of saltpeter is a little small, and the sugar water in the copper basin is not very well frozen, only a few pieces of floe ice are frozen, but the water containing saltpeter in the wooden basin is completely frozen.

"You can really make ice, but it's a pity that Miss isn't here." Guo Dudao.

"Just a bag of saltpeter can turn water into ice?" Old Doctor Ge looked at Zhao Yuan and asked.

"Yes, when the nitrate is in the water, it will absorb a lot of heat, and the water will freeze, and in some prosperous cities, some merchants sell ice in summer, which is how it is obtained." Zhao Yuan said with a smile.

"Quick, give me a taste." Doctor Ge couldn't wait to say.

"It's a little less, Xiaoqi, you can divide it for everyone." Zhao Yuan said with a smile.

The ice containing saltpeter in the wooden basin is not edible, but it can be put in the house to cool down, and when the ice in the wooden basin melts and dries, saltpeter can be obtained again.

After Xiao Qi gave no one a glass of sugar water with ice cubes, Zhao Yuan picked up a glass of ice water and began to taste it.

"Hey, comfortable." A cool breath slid from the mouth through the throat, penetrating the heart and making the heart fly.

"Brother Zhao, you have such a secret recipe, you can open a shop in the city!" Squinting his eyes and tasting the sugar water and ice drink, Dr. Ge said.

"I don't have the energy or time." Zhao Yuan smiled and shook his head.

"It doesn't seem like it takes much effort, in terms of saltpeter, I have a channel here, but the cost is too high, so much saltpeter, to make these edible ice, but this cold thing, you can't eat more."

"This saltpeter can be used again, although it is in the ice now, but it can be used again after the ice melts and dries." Zhao Yuan said with a smile.

Zhao Yuan has no idea about making summer ice drinks, but Xiao Qi on the side is a little moved, he has been working in Wanjia for so many years, and he has also saved some money, I don't know if I can talk to Master Zhao, let the family come to the city to sell ice, in the past, Wanjia bought ice here, and I heard the purchasing manager say that the price was very expensive.

"Master Zhao, can we use your secret recipe?" Xiao Qi asked a little apprehensively.

"Do you want to make your own ice water to drink, of course, don't forget to bring me a glass when you make it." Zhao Yuan said with a smile.

"It's not...... Oh, no, it's not ......, I mean, can I let my family use this secret recipe to sell ice in the city? Xiao Qi asked with a little stammer.

"Do you want to open a cold drink shop?" Zhao Yuan thought for a moment and asked.

"Either open a shop, or make ice and sell it in the city, my family's money is not enough to open a shop." Road.

"Miss Xiaoqi, you don't have enough money to open a shop, I have some money here that I can use first." Without waiting for Zhao Yuan to speak, Shao Meng on the side said.

"Who wants your money, besides, Master Zhao hasn't agreed yet." Road.

"Is this, is there a situation? Xiaoqi, I have no opinion on you using this formula. Zhao Yuan looked at the two and said with a smile.

In the past six months in Zhao Yuan, he basically doesn't spend his own money on food and housing, Shao Meng and the others have each saved some money, and Shao Meng is the oldest among them, and he has reached the age of saying goodbye.

"No, no, Dr. Ge, can I buy saltpeter from you, you can always give me a cheaper." Xiao Qi hurriedly waved his hand, and ran to Doctor Ge as if evasively asked.

"Yes, Miss Xiaoqi can come to Jishitang to find me at any time, but it's still quite heavy to buy too much saltpeter, and someone needs to help carry it." Doctor Ge said with a laugh.

Among Xiaoqi, Xiaocui, and Xiaojuan, Xiaoqi is a native of Danling, and has been working in Wanjia since he was a child, and his family rents land outside Wanjiacheng, which is considered to be employed by Wanjia. And Xiaocui and Xiaojuan were indeed sold to thousands of homes because their families were poor.

"It looks like there's a play." Zhao Yuan looked at Shao Meng and Xiao Qi, and thought secretly in his heart. When the time comes, talk to the second brother and promote these two people.

In Zhao Yuan's view, he has no culture, but he is smart and clever, and he is quite disciplined, and Shao Meng, after a few months of work and training, has changed a lot and is quite capable. If the two can succeed, it will be a good thing. Zhao Yuan rolled his eyes and smiled secretly that he was going to be a matchmaker.

With a basin of ice to provide cool air, everyone also returned to the house, Zhao Yuan chatted with Dr. Ge, from the medicinal properties of saltpeter to Dr. Ge's profession, Zhao Yuan's erudition made the old doctor admire.

"I can see it, Brother Zhao, you can be a doctor." Old Doctor Ge said depressedly.

"I'll just talk about it, but I don't know how to heal." Zhao Yuan said with a smile.

"Brother Zhao really doesn't have the development of medical skills, as long as you learn medical theory and accumulate cases, I guarantee that you can definitely become a generation of divine doctors like Zhao Si Divine Doctor, and even higher than Zhao Si's achievements."

Zhao Yuan has more than one classic book about medical skills in his mind, not only has a lot of knowledge of traditional Chinese medicine, but also a lot of knowledge of Western medicine.

"I'm very lazy, it's enough to be a doctor, with people like the fourth uncle and the old doctor." Zhao Yuan said with a smile.

"It's a pity."

"By the way, my fourth uncle's medical skills were not so high before, but after carefully studying the "Thousand Golden Prescriptions" of the former medicine king, his medical skills improved, and when the fourth uncle came back, I asked the fourth uncle to show you this book." After chatting with Doctor Ge, Zhao Yuan knew that Doctor Ge was a person with noble medical ethics, so he said.

"What, the Medicine King's "Thousand Golden Prescriptions", I heard that the Medicine King wrote such a classic, but I have only heard about it, but I didn't expect it to be obtained by Zhao Si Divine Doctor." Doctor Ge said in shock.

"Serendipity, serendipity." Zhao Yuan said with a smile.

After the book was written, although it was copied and cited by everyone, the whole book was rarely circulated, and it was not officially published.

"Can I really see something so precious?" Doctor Ge asked incredulously.

"Of course, when the fourth uncle comes back, I'll ask him to bring you a copy of the book." Zhao Yuan nodded and confirmed.

……

After sending the old doctor away with anticipation in joy, Zhao Yuan learned some about her family's situation with Xiaoqi, and gave a lot of pertinent opinions and suggestions for this girl who wanted to start a business, which made Xiaoqi firm in his idea of making summer ice drinks. 8)
