At night, the crickets sing.

After writing a very long letter, Sun Ruowen, the god of medicine, tied the letter and a medicinal herb to the leg of the big snow sculpture, and let the eagle fly to the sky, fly to the Qinghai-Tibet Plateau, break through the layers of clouds and mist, and fly into the vast snow-capped mountains. It was one of the ten major tribes in Tibet, and there was also a medical saint living there. Even the blocking of time and space and the division of national borders could not stop the enthusiasm of the two to exchange medical Taoism.

Wu Yueya returned to her mansion and learned that the fat businessman was called Ding You, who was originally from Chang'an. He has a wife and a concubine, and has three young sons, and his parents died early, selling small things, which is barely enough to make ends meet.

Through Wu Yueya's repeated inquiries, this Ding You truthfully informed that the two loads of saltpeter were found on a wild mountain outside Chang'an.

The fat man Ding You was originally poor, but his body was blessed, he loved meat and couldn't afford to eat meat, so he had to go to the mountains to hunt, and found that this saltpeter was exposed on the surface, and when he dug it up, he saw that there was a lot of saltpeter buried at the foot of the mountain, so he wanted to dig it out and pick it up to Chang'an City to sell. Just do it, but the pharmacy saw that he was poor and wanted to lower the price. Ding You's chest exploded, and after a few words, he left, and happened to run into the princess.

Under the exchange of several conditions from Wu Yueya, Ding You not only told the saltpeter mine, but also joined the princess's mansion. Although the impression is not good, Wu Yueya thinks that this guy is eloquent, it is good to let him be the shopkeeper when he opens a wine shop, and he can still deceive people or something.

One of the things I care about the most is saltpeter powder, which can be cooled when melted in water, and it is really good to make cold drinks or ice cubes.

Let Ding You work hard, mash some saltpeter, bring it to Tianci Pavilion, and then return to the ear room to rest.

"Little lady, what are you doing here?" Li Wan'er put a bucket of water on the round table and wiped the sweat from her forehead.

"Does Wan'er like to eat ice?" Wu Yueya did not answer the rhetorical question.

Li Wan'er thought for a while, and then replied uncertainly, "Wan'er doesn't seem to have gnawed on ice in winter..."

Wu Yueya was speechless, too, after all, the summer is so hot, where did the ancients get the ice, even if there is, it can't stay in the summer, the winter is so cold, what cold drinks to eat, there is no invention if there is no demand, Wan'er must not have drunk cold drinks on a hot day or something.

But it's not bad to make a bowl of cold drinks now, although it's still the beginning of autumn, it's still a little hot at night, so let Wan'er taste it later.

Wu Yueya touched the temperature of the silver basin, and it was already warm. The white cane sugar water was soaked in the silver basin, and Wan'er and Chu'er liked this thing very much. Aya Wu also likes that as a modern person, the taste buds have long since undergone the ultimate evolution and become the ultimate body.

The little lynx swaggered in, followed by a little brother, Little White Tiger. The two little ones revolve around the master, the little lynx has grown up, heavy, and the cat's body has begun to fat, and recently it has always eaten fragrant meat at the master's place.

Let it climb on her shoulders, Wu Yueya felt that her shoulders sank, this little guy, is it so heavy, but it's real, I didn't notice it before.

Holding it down, Takezuki Aya began to pour saltpeter into the barrel, and after pouring it, the covered silver basin was put on the surface of the water and secured, and soon a miracle happened.

Hua Chu'er also curiously fell from the roof of the building and climbed through the window, came to the barrel, and felt a cool breath blowing, which felt more comfortable than the night breeze blowing.

Wan'er watched in disbelief as the wooden barrel slowly formed ice cubes, and looked at the little lady with her mouth open, thinking that this was the little lady's fairy art.

Wu Yueya grinned, patted Wan'er's face with both hands, and kneaded it vigorously, "You, just, no, want, this, what, surprise, surprise!" It's a very simple chemical reaction, and a cold drink is immediately available. ”

After a long time, the changes in the bucket stopped, Wu Yueya took out the iced silver basin, lifted the lid, and a cold white gas came out, the surface of the sugar water was already frozen, picked up a small wooden hammer, began to break the ice on the surface, and then poured it into the bowl, and one person shared a share.

Hua Chu'er drank a bowl first, her teeth gritted the ice cubes and slammed them, sweet and thirst-quenching, it was still ice, how did the little lady get it.

Li Wan'er took a sip, choked, coughed lightly a few times and began to drink in a big gulp, it was so delicious, it turned out to be ice.

"Little lady, I still want it!" Hua Chu'er said immediately after drinking.

Li Wan'er took a sip of the remaining sugar water from the corner of her mouth, and decisively picked up the silver bowl with both hands and stretched it out to the little lady like Sister Chu'er, I want it too!

Wu Yue Ayale got up and gave each of them a bowl, "Okay, okay, you are both princesses tonight!" ”

The three of them smiled heartily, and said that the night had passed so happily... Well, 99.9% of Hua Chuer, who drinks too many cold drinks, is squatting in the toilet... (The unique toilet of the Tang Dynasty has something to do with pigs...) ）

On the second day, the autumn sun rose as usual, the days did not change much, and everything was as usual.

Yu Chaoen brought news that the peppers had bloomed.

This news is not bad, but Wu Yueya has long known that the pepper is blooming, and Hua Chu'er reported it to her in the morning, although she doesn't know why she found it earlier than Yu Chaoen, but there is no need to care so much.

Wu Yueya sat on the bluestone steps of Tianci Pavilion, looking up at the sky, a figure flashed in her mind, it was Lu Ziji, and she wished in her heart, hoping that Brother Lu could be relieved.

This kind of miss is only for a moment, and she asked Xiaomi next to her to call Yu Chaoen.

"Princess, just give me orders!" Yu Chaoen bowed his head respectfully and stood in front of Wu Yueya.

"I'll give you one thing, pull the princess's personal guard out, and buy me all the poor families in Chang'an City who sell their sons and daughters, the most important ones are those who sell children about twelve years old, this matter must be done for me, and the matter of chili land will be put aside for the time being!" Wu Yueya tapped her fingers on her knees, supported her chin with one hand, and expressed quietly.

"Yes, the little slave must do it! It's just—" Yu Chaoen solemnly assured, and then stopped talking.

"Say!"

"The princess is a daughter, please don't go to the field to plough the land, just leave it to me and other slaves!"

"Well, I see, you go down!"

"Yes, thank you for your understanding!"

Yu Chaoen walked down, first returned to the ear room where he lived, touched the harrier that passed on the credit, took out a piece of dried fish and fed it to eat, and then knelt down on the couch in front of the bookcase, and wrote a few times.

Probably talking about the princess's movements, the princess's house is scarce, and the princess wants to buy teenage children to raise as confidants...

Yu Chaoen continued to write, copied a copy of the letter, put it on the bamboo slips on the legs of the two harriers, and stood in front of the harriers for a while. He looked at the harrier, and the harrier looked at him.

Untying the clothes on his chest, Yu Chaoen glanced at the remaining wounds that had not yet healed, his eyes narrowed in a dangerous arc, and then he put on his clothes neatly, took out the letter from the bamboo tube of the harrier's legs, lit the letter with flint, burned it to ashes, and then pushed open the door, and led the princess's order towards the place where the princess's personal guard was stationed.

The door closes, leaving only black ashes drifting in the sunlight under the windowsill...

At the same time, in the Manichaean gambling house in the west city of Chang'an. Yang Zhao (Guozhong's former name) carried a chicken that was killed by fighting, with a few chicken feathers on his head and a purple piece on his body, this is the thirteenth time he has come to gamble, and now it is impossible to borrow money anymore, and the notoriety is all over the family.

He walked down the street in a daze, except for the dead chicken in his hand, all he had left was a pair of long underwear, which was pointed at by pedestrians, and many of the women who were shopping closed their eyes and turned away to look at him with disdain. A month later, under the arrangement of his family, he walked on the grass covered with hoarfrost, followed a group of refugees, and led the government's order to go to Jiannan.
