In the small courtyard, Zhao Yuan reclined on a reclining chair, directing Shao Meng and Xiao Qi to prepare for ice making.

After waiting for a while, Zhao Yuan fell asleep on the recliner in a daze.

Shao Meng saw Guo Du and Xu Xiang return to the small courtyard with Doctor Ge.

"Master, wake up, Guo Du and they are back, and there are guests." Looking at Zhao Yuan, who seemed to be asleep on the recliner, Shao Meng stepped forward and patted him lightly and said.

"I'm back, why did I fall asleep?" Zhao Yuan rubbed his face with his hands, got up and looked outside the house.

"Master, we're back, this is Old Doctor Ge from Jishitang." Guo Du was carrying a bag containing saltpeter, and when he saw Zhao Yuan looking at Ge Qing, he hurriedly introduced.

"Welcome, Doctor Ge, I'm Zhao Yuan, please in the house." Although I don't know why a doctor will follow, but it is a guest at the door, Zhao Yuan greeted.

"Brother Zhao, I took the liberty to come to the door and disturbed me." Doctor Ge stroked his beard and said.

Several people came to the hall and sat down the host and guest, and Guo put saltpeter on the table beside him.

"Master, Dr. Ge is not worried that we will buy so much saltpeter, for fear that we will use it blindly, so we must follow and take a look to rest assured."

"I'm just worrying, when I look at Brother Zhao, you are not a messy person." Ge Qing said with a smile.

"Doctor Ge is benevolent, and the kid admires." Zhao Yuan stood up and arched his hand.

"When I was in Jishitang, how could I say that the old doctor didn't believe it, and he didn't sell us all the saltpeter in the pharmacy, but only bought back twenty-five catties, I don't know if it's enough?" Seeing this, Guo Du also said with a smile.

"The pharmacy needs to have medicine on hand, what if there is a patient who needs it, and the pharmacy is gone." Old Doctor Ge glared at Guo Du and said.

"Yes, yes, didn't you leave a lot of it!" On the way back, Guo Du realized the old doctor's mouth.

"Be polite to Dr. Ge, how can you speak?" Zhao Yuan also glared at Guo Du.

"That is, do you know how to respect the elderly?" Doctor Ge also said loudly.

The old doctor was about sixty years old, his hair and beard were gray, but his face was ruddy, he looked energetic, and his voice was loud, very similar to the old Chinese medicine doctor that Zhao Yuan had seen in later generations.

"Master, you don't know who Doctor Ge admires the most, it's the fourth uncle of the master, Mr. Zhao Si." Guo Du drank Zhao Yuan, didn't feel anything, and said with a smile on his face.

"What, you are the junior of Doctor Zhao Si, do you know where he went, I still want to ask him for advice, one of my patients, I thought of a lot of ways to be cured, as soon as I took over Doctor Zhao Si, I will get rid of the disease immediately?" Doctor Ge said in shock.

"I don't know where the fourth uncle went, but he stayed in the county for almost two months, didn't you see him, Doctor Ge?" Zhao Yuan asked.

"He's too busy, how can I bother." Doctor Ge said with some pause.

In fact, it wasn't because Zhao Si was too busy that Ge Qing didn't go to get acquainted. When Zhao Si first came to the county to give everyone a low-cost or free medical treatment, he had already heard of Zhao Si's name. However, I heard that Zhao Si was not very old, so Ge Qing was not interested, and said to the guy and granddaughter in the pharmacy at that time that such a person only knew a few home remedies, so he was ashamed to treat everyone.

Later, Zhao Si's reputation became bigger and bigger, especially after curing several old patients that Ge Qing had treated, he knew that he had gone away this time, and later he was embarrassed to see Zhao Si. However, the Zhao Si in his mouth has also changed from the original barefoot Langzhong to the current Zhao Si divine doctor.

"It's a pity, I don't know where the fourth uncle is now, otherwise I can introduce you to Dr. Ge, the fourth uncle has always been very obsessed with medical skills, and he can learn two hands from Dr. Ge." Zhao Yuan didn't know that there was such a section in it, and said with a smile.

Zhao Si really has the talent of a doctor, and in the original village Langzhong, he was able to reach the current level with only a "Thousand Golden Prescriptions" given by Zhao Yuan, and now he is famous in the county.

"Don't worry, by the way, Brother Zhao, what are you buying so much saltpeter for, you can't follow those Taoist priests to use for alchemy or something, that thing is not a good thing." Doctor Ge asked.

On the way here, Guo Du repeatedly assured the old doctor that saltpeter was not used for eating, but it was related to Zhao Yuan's ice-making, and he never told the use of buying saltpeter back.

"It's not alchemy, I'm not interested in that, I bought saltpeter and came back just to make some stuff." Zhao Yuan said with a smile.

"You're not going to make gunpowder, are you?"

"No, Dr. Ge, if you have time, let's take a look." Zhao Yuan said with a smile.

For saltpeter ice, Zhao Yuan did not intend to keep it a secret from everyone.

"Okay, I'm free."

"I'm going to bring in what I've prepared." Shao Mengjian and Zhao Yuan were about to make a move, so they were about to walk towards the courtyard.

"Don't move into the house, let's go straight to the yard, Dr. Ge, please." Zhao Yuan waved his hand and said to Old Doctor Ge.

Xiao Qi and the three of them were about to serve tea to Ge Qing and Zhao Yuan, and when they saw this, they had to bring the tea to the courtyard.

"You guys have a good deck chair, I sit?" When he came to the courtyard, Dr. Ge saw the recliner where Zhao Yuan was sitting, his eyes lit up, and he said with a smile.

"Doctor Ge, please." Zhao Yuan smiled and nodded.

Wooden basins, copper basins, clear water, lids, saltpeter, sugar, everything was ready, and Zhao Yuan took a few people to start operating.

"What are you doing here?" Looking at the pile of things in front of him, Old Doctor Ge was completely confused.

"Master Zhao is going to give us the immortal method." Said from behind Doctor Ge.

"Where are there immortals in this world, and there are still immortals, little girl, where are the gods and gods in your head." Old Doctor Ge shook his head and said while drinking tea.

"Why not, I know that there are Jade Emperors, Monkey King ......" Xiao Qi heard the old doctor's words, and defended dissatisfiedly, spit out a lot of fairies and ghosts in his mouth, it seems that she is a fan sister of "Journey to the West" again.

"That's just a myth and a story, the old man has lived for so many years, and he has never seen these fairies and ghosts you said." Old Doctor Ge put down the teacup and said with a smile.

"Hmph." Xiao Qi didn't know what to say, snorted lightly, ignored Doctor Ge, and watched Zhao Yuan's operation intently.

Zhao Yuan saw that the amount of saltpeter brought back by Guo Du and Xu Xiang was not large, and he was worried that the ice making would not be successful, so the water brought from him had passed for a while, and the temperature had risen a little.

"Go get a bucket of water again, it's not cold anymore." Zhao Yuan said to Shao Meng.

In summer, the well water is very cold, and the lower the temperature, the less energy needs to be sucked away when the water freezes, and the more likely it is that ice production will be successful.

The saltpeter bought from the pharmacy has been processed, and the purity looks quite high, and it is all fine and small crystals.

When Shao Meng brought the well water again, Zhao Yuan put the saltpeter into the big basin, carefully paved it in the basin, and then prepared the place where the copper basin was placed in the middle of the basin, thickened and put some saltpeter, and put all the saltpeter brought by Guo Du into the basin.

"Hey, it's all in the basin?" Old Doctor Ge frowned and looked at Zhao Yuan's operation.

Zhao Yuan put sugar and water in the copper basin and stirred it to dissolve all the sugar into the water, put the small copper basin filled with a small half basin of sugar water in the center of the large basin, poured a certain amount of water into the large basin, and immediately covered the entire large basin tightly with a lid.

"It's really strange, the old man still doesn't understand what you're doing?" When Zhao Yuan finished getting it, Old Doctor Ge said loudly.

"Doctor Ge, you'll find out in a moment." Zhao Yuan smiled mysteriously at everyone. 8)
