After the prosperous Tang Dynasty

It's almost summer, and the flowers in Duke Yan's mansion are blooming brightly and delicately.

As soon as Li Wenning came in, Princess Ningqin who came up to her greeted her kindly and took a close look at her with a smile. Then she sat together and said: "The last time I saw you was in Xingqing Palace, half a year has passed gone."

Li Wenning showed a slightly shy smile, leaned on Princess Ningqin, lowered his voice and dared to say softly: "I have always missed my aunt, and my father often talked about things when I was a child in private, but——"

Princess Ningqin stretched out her hand and gently covered Li Wenning's unspoken words, and after she directly pushed back all the maids waiting in the room, she showed a trace of sadness and helplessness, and said softly: "His Royal Highness and I are together. From his mother, his situation is unknown to others, but I understand it..."

Yan Guogong Zhang said that he had been prime minister for many years, and he assisted Xuanzong to create a prosperous Kaiyuan Dynasty. He had worked hard and made great achievements, so he naturally had a high position and weight.

Previously, Xuanzong had listened to Concubine Wu Hui's slander, demoted the abolished prince Li Ying, E Wang Li Yao, and Guang Wang Li Ju to the common people, and even ruthlessly executed the three sons together, which made the kings quite frightened.

Under such circumstances, even if Li Heng was appointed as the prince by Xuanzong, he still felt as if he was facing an abyss and walking on thin ice.

What's more, Xuanzong himself had no intention of defending Li Heng's status as the crown prince, otherwise, Li Linfu and others would not have attacked the crown prince so blatantly.

Li Wenning is only an 11-year-old girl now, but, as the third daughter of the prince, she was born in the palace, and grew up in the top power center since she was a child. Some things have long been her instincts.

Nestling beside Princess Ningqin, Li Wenning did not hide it, but directly told the news that Prince Li Heng learned at the court meeting in Xingqing Palace today, but of course she would not mention it, and she came to the Duke of Yan's mansion by herself The purpose of visiting Princess Ningqin was to ask her cousin Zhang Dai about what happened at the foot of Ximing Temple...

"On that day, Wen Ning happened to be in Ximing Temple with his elder brother and third younger brother." Li Wenning said softly: "Later, I met my cousin outside Ximing Temple, and he just said hello and passed. Today, I heard my father tell Xiao Liu After what happened to Mother, the more Wen Ning thought about it, the more afraid he felt, and he couldn't help but want to visit his cousin..."

When Princess Ningqin heard this, she was also frightened for a while.

At Xu Guogong's mansion, Pei's famous post was sent over early this morning, saying that she would come to pay her respects. Princess Ningqin naturally also knew about her Jiulang Zhang Dai's helping Liuniang of the Xiao family.

However, she only thought that Xiao Liuniang and Pei Shi were separated, and then met Jiulang, and the two of them sat and waited together in the tea shop for a while, who would have thought that Xiao Liuniang had encountered such danger before, and, That villain even met his own Kuro head-on...

For the first time in her life, Princess Ningqin was glad that Jiulang from his family was a domineering man since he was a child, and he was spoiled by Yan Guogong Zhang Shuo and was naturally arrogant. Know how ostentatious he is.

However, even being secretly pointed at, ridiculed by a dude, or even bullied, is much more reassuring than having no one around when you are in danger...

"That little bastard, you didn't even tell me about such a big thing!" Princess Ning covered her heart, and immediately became scared. She took two deep breaths before she calmed down a little. She held Li Wenning's hand , Thinking of his son, he couldn't help murmuring: "It's a good thing you miss him, otherwise, I'm afraid I won't know what's going on until Mrs. Pei comes here in person."

At this time, the sky was getting late, and the afterglow of the setting sun slanted in through the exquisite carved wooden panes.

Li Wenning looked up, guessing that it was time for school to end, and Zhang Dai would be back soon.

Princess Ningqin naturally remembered this, and said to the maid who was waiting outside, "Qingluo, you go to the door and wait for a while. When Jiulang comes back, bring him directly to my place."

The servant girl who was called Qingluo immediately responded crisply.

Princess Ningqin pulled Li Wenning to talk for a while, and about a quarter of an hour later, there was the sound of brisk footsteps like a gust of wind, and Zhang Dai, who was dressed in exquisite silk and satin, had already rushed in, "Aniang, are you looking for me?"

After the words fell, Zhang Dai saw Li Wenning who was sitting there with a smile, and couldn't help showing a little surprised expression, "Cousin is here too?"

Li Wenning said generously: "I heard about Xiao Liuniang's injury, and remembering that you were also in Ximing Temple at that time, I couldn't help feeling a little worried, so I came to see you."

After all, Zhang Dai was still young at this time, and his mind was straightforward. After listening to Li Wenning's words, he didn't think much about it at all. On the contrary, he still had a bit of heroism that he hadn't finished displaying in front of Xiao Yansui, who looked very well-behaved yesterday. When he came up, he waved his hand and said boldly: "Cousin, don't worry, Jiulang is not afraid of those villains!"

Princess Ningqin hugged her little son, and couldn't help pinching his little face lightly. After hearing what he said, she wished she could just shut him up at home and endorse him honestly. Do mother's worry.

Li Wenning just said: "Don't worry, Ximing Temple was so dangerous yesterday, I still feel afraid when I think about it, my aunt and I are thinking about you, so it is impossible to let go."

Princess Ningqin nodded in agreement, but Li Wenning's words touched her heart.

After hearing these words, Zhang Dai was a little shy. He scratched his head, and after a while, he regained his energy. Without asking Li Wenning and Princess Ningqin, he fully described his "heroic and martial arts" yesterday. He showed off all his actions again, to reassure his mother and cousin.

As he was talking, thinking of Xiao Yansui who was sitting in the tea shop very quietly and obediently yesterday listening to him, Zhang Dai's words paused for a while.

——Yesterday I seemed to say that I want to take her to release paper kites!Spring is almost over, and after summer, it will not be so easy to find a windy weather suitable for flying paper kites.However, Xiao Yansui still has injuries on her hands, so she has to wait until she recovers from her injuries, and I don't know when she will be able to come out to play with her...

Li Wenning just listened quietly, but kept all the important things in his heart, and after having dinner with Princess Ningqin and Zhang Dai, he took the carriage and returned to the Prince's East Palace before the dark night completely engulfed him. .

After Li Wenning returned to the East Palace, he first went to see his father, Prince Li Heng, and repeated Zhang Dai's words emphatically, before saying: "According to what Cousin Dai said, those villains are really not good enough to stand on the stage. A ruffian and a rascal, the guards around him will clean up those people as soon as they make a move, it really doesn't look like a reliable person."

Prince Li Heng couldn't help but fell into deep thought, muttering to himself: "The surrounding area of ​​Ximing Temple has been quiet for a long time, how can it be such a coincidence that there is a group of local scoundrels who didn't come early or late, but happened to bump into it yesterday."

"Maybe someone is behind the scenes." Li Wenning said.

Prince Li Heng frowned slightly, lost in thought, he waved his hands casually.

Seeing this, Li Wenning didn't say much. After saluting to his father respectfully, he quietly withdrew.

Prince Li Heng was the only one left in the study. His eyes scanned the picture scroll on the case, and he thought to himself that Li Chu had already painted the portraits of those three people. Li Wenning said that those people were probably ordinary marketers. Scoundrel, in this way, if you want to find out the whereabouts of those people, you might as well find a reliable broker on the streets of Chang'an City and let them search for them.

After all, those guys who have become brokers, among other things, the best thing is that they know everyone from all walks of life, and they can get connected and get online...

Outside the window, the moon is white and the wind is clear.Inside, candles flickered.

Xiao Yansui sat in front of the desk, a bean lamp reflected her fair and tender face, as if it also dyed it with a touch of warm color.

After putting down the pen, Xiao Yansui recalled the whole process of the saponification reaction that he had just written, turned his head slightly, and caught a glimpse of the whole set of distillation equipment. And the inconvenient fingers slowly wrote stroke by stroke: "caustic soda, lard, distilled water, spices, long-handled copper spoon, pure copper pot..."

In fact, the saponification reaction is very simple, but because the main component of porcelain contains silicon dioxide, especially the surface part, and sodium hydroxide will react with silicon dioxide in a high temperature environment to form sodium silicate and water, which will lead to the failure of experimental equipment. Therefore, the casserole used in the distillation is completely excluded. It is better to choose a copper vessel made of simple copper as the container for the experiment.

After Xiao Yansui made the list, she handed it directly to Axiu, "Prepare a copy for me tomorrow."

Axiu nodded, took a look down at the list, and then was stunned. The pure copper pot and the long-handled copper spoon are all good. Together with the lard, there should be ready-made ones in the kitchen. For spices, Liu Niang's It's in the house, and as for caustic soda—

Axiu hesitated and said, "Liu Niang, caustic soda is too dangerous..."

Xiao Yansui blinked, just looked at Axiu, but didn't speak.

Axiu has always known Xiao Yansui's temper. She is obviously a child, but she usually behaves quite mildly. She seldom loses her temper, but she also has big ideas.

As long as it is Xiao Yansui's decision, there are very few people who can make her make a change on weekdays, and it is even more difficult to make her give up...

Meeting Xiao Yansui's calm eyes as if nothing had happened, and after a while, Axiu gave in quickly, and replied in a low voice: "My servant understands, I will send someone to arrange it tomorrow morning, and I think it will be fine before noon."

Xiao Yansui finally smiled and nodded slightly.Knowing that there is already caustic soda at this time, for herself, it saves a lot of effort, otherwise, she would have to think about making sodium hydroxide from slaked lime.

However, after a pause, Axiu looked at the list carefully, and asked with some uncertainty: "Liu Niang, what is the so-called distilled water?" She subconsciously glanced at the distilling device used today, It's a bit of a guess in a trance, but I'm not sure.

Xiao Yansui let out a soft "Oh". I used to say that I was used to it in the laboratory, and today I happened to use the copycat Tang Dynasty version distillation equipment to get two bottles of distilled alcohol out, so that Xiao Yansui listed When I made the list, I wrote it down with distilled water.

But to be honest, if you just want distilled water, there is no need to use this device. The big pot for cooking on the kitchen stove collects the water droplets formed by the condensation of water vapor hanging on the pot lid. It is already ready-made distilled water.

Thinking of this, Xiao Yansui simply said directly: "Tomorrow, when the big pot on the stove is used to boil water in the kitchen, first clean the lid of the pot, and then just put the water on the lid away for me. .”

Axiu nodded immediately, this is easy, and there will be time to tell the kitchen staff to do it tomorrow morning.

After arranging everything properly, Xiao Yansui got up from the case and went back to the bedroom, intending to lie down and sleep.

In ancient times, there were no electric lights, and candles were lit at night. The weak light really hurt the eyes. In addition, if you make yourself nearsighted now, there is no place to wear glasses, so even if you are bored, Xiao Yansui still tries to Avoid reading and writing at night when there is insufficient light.

In order to pass the time, sometimes lying in bed early but unable to fall asleep, Xiao Yansui memorizes the periodic table of elements or the square root table in his head when he has nothing to do. Some things are not easy to write down by yourself, so you have to keep them firmly in your mind. The most reliable.

The most common numbers in the student days, the square root of 2 is approximately equal to 1.414, the square root of 3 is approximately equal to 1.732, and the square root of 5 is approximately equal to 2.236. Xiao Yansui has long remembered these commonly used numbers in exams. It's a kind of thing, maybe one day it can be used when calculating formulas.Now, I often do mental calculations every night before dreaming. After a long time, the number of commonly used numbers in Xiao Yansui's mind has expanded many times than before-the more I don't have a computer, the more I use my brain.
