After hearing Jia Jiayin's words, Li Zexuan suddenly realized that he had just been wondering why these students were still washing clothes at this time. It turned out to be because they were washing too slowly without the help of saponin!
The earliest ancient people used plant ash as a stain remover because it contains potassium carbonate, which can remove dirt from clothes. In addition, according to "Kaogong Ji" records: When practicing silk, use the railing as ashes, and the silk will be pure and pure, and the mirage will be shaken. The mirage in this sentence is shell ash, which contains calcium hydroxide. When mixed with plant ash, it can generate potassium hydroxide. When it is soaked in water to wash silk fabrics, it reacts chemically with the oil attached to the surface of the silk fabric to form "potassium soap" , can wash silk fabrics clean and bright.
Later, the ancients in the Wei and Jin Dynasties began to use soap locust and bath beans to wash clothes. The soap locust can generate foam in water and has decontamination properties. Later, Sun Simiao invented a new method of washing clothes, which was to wash the dirty blood on the pig pancreas, tear off the fatty liver on it and grind it into a paste, add soybean powder and spices, stir evenly, and air dry in a ventilated place. It becomes a bath bean that can wash away dirt from clothes.
"Okay, I understand~! However, military training is a special period, and the conditions will naturally be difficult. You don't have to be too particular about it, as long as your clothes don't stink! After the military training, everything that should be available in the academy~!"
Li Zexuan said lightly.
At the beginning of the construction of the academy, he did leave some space for shops, but he has been too busy and has not had time to "attract investment", so except for the cafeteria, there is basically no other place to spend money in the academy.
As for whether to make soap or not, it depends on whether he is in the mood.
"Yes, Chief Shan~! Students understand~!"
Jia Jiayin cupped his hands and walked towards the dormitory.
Li Zexuan nodded secretly in his heart, thinking that although this child looks a bit fierce, his character and knowledge are not bad. Men, in the end, rely on talent and learning. In ancient times, there were many celebrities who were ugly but eventually became famous.
"Stand at attention~!"
After Jia Jiayin left, Li Zexuan yelled loudly, and then said: "Start standing in a military posture, Pang Feiji, you are here to supervise them. If anyone moves irregularly or is lazy secretly, he will be given extra time~! Do you understand~?"
Pang Feiji wiped the sweat from his forehead. There was a prince and two princes here! Li Zexuan asked him to keep an eye on him. Wouldn't this cost him his life~?
"Hmm~?"
"Yes~! I understand~!"
Under pressure from Li Zexuan, Pang Feiji quickly agreed.
Li Zexuan nodded with satisfaction, and then said: "Yeah~! Starting from tomorrow night, after midnight, you and other instructors must check the dormitories one by one. If you find out who violates discipline, the punishment method will be the same as today. Before midnight, You are not allowed to sleep, do you understand~?"
"Yes~! Chief Shan~!"
Pang Feiji felt miserable~! They are actually quite tired as instructors during the day, but now that they are drafting like this, they have much less rest time!
............................
Thousands of miles away, in the Japanese country, Mubang Mountain outside Asuka Capital.
"Your Majesty, the king of Japan has sent an envoy. He is now outside the camp. Do you want to see him~?"
In the Chinese army's tent, Li Xiaogong was looking at the big map on the table, when suddenly a messenger came in and bowed.
Li Xiaogong raised his head and said calmly: "Let him come in~!"
"No~!"
After a while, a short man wearing Japanese clothes came in, bowed to Li Xiaogong and saluted: "Ono Yoko has met His Royal Highness~!"
This sentence can be said in extremely pure Chinese, and it also has a Guanzhong accent. Li Xiaogong raised his eyebrows and said: "You can also speak Chinese~?"
Ono Yoko bowed slightly and said: "The culture of the Central Plains is profound and profound, and everyone in the Japanese country admires it greatly. I just relied on my late father's influence and studied in the Central Plains for a period of time, so I can speak some Chinese~!"
In 607 AD, the first government mission sent by Japan to the Sui Dynasty of China finally arrived in Luoyang. The leader of the mission was Ono Meizi, the father of Yoko Ono.
In 609 AD, Ono Meizi came to China again as an envoy to send the Sui envoys back to China. It also brought a group of overseas students and monks studying abroad. Yoko Ono was also among them at the time. Therefore, Yoko Ono knows very well about the customs and culture of the Central Plains.
Li Xiaogong nodded slightly and communicated directly with a Japanese who could speak Chinese. He would feel more comfortable. After a moment, he asked: "Why did Queen Tuigu send you here~? Why doesn't she come to see me in person~?"
Arrogant!
It can be said that Li Xiaogong's attitude is extremely arrogant! But Ono Yoko's expression only changed slightly and she did not dare to make any rebuttal.
"Go back to Your Majesty, Your Majesty, she is in poor health and cannot leave the palace. I hope Your Majesty will understand~!"
Yoko Ono said slowly.
"Hmph~! Is it inconvenient to leave the palace~? Does she still want me to go to the city to see her in person~?"
When Li Xiaogong heard this, he glared and said angrily.
Ono Yoko quickly made a look of sincerity and fear, and bowed down: "Your Majesty, I forgive you, but it is true that Your Majesty, she is old and has been in poor health recently, so she really cannot leave the palace."
"Already old? How old are you~?"
Li Xiaogong asked a very rude question, but who gave him a strong army? Wherever there is strength, he is the boss. Weak countries have no diplomacy, while strong countries retain hegemony! This is a principle that can be applied in any era.
Ono Yoko's face turned red. He gritted his teeth and said, "Go back to your lord, Your Majesty, she has entered her seventies this year~!"
(Sixty sixty, seventy is rare since ancient times)
Li Xiaogong actually didn't know the age of the Queen of Japan at first. After hearing this, he said "Oh" in surprise, and then said: "That's it~! It seems that Queen Tuigu really wants me to enter the city to see her~?" "
Hearing this, Ono Yoko was inexplicably excited, but with a flattering smile on his face, he said: "When we came down, the Holy One said that if the prince is willing to condescend to enter the palace to see you, he will definitely receive the most solemn welcome from Japan. Golden beauty, when the time comes, The prince will definitely enjoy it~!"
"Asshole~!"
Li Xiaogong slapped the table and said angrily: "How dare you use this bitch to seduce this king~?"
"Yes, yes, yes~! I said something wrong, please forgive me~!"
Ono Yoko was very angry in his heart, but in fact he kept slapping himself in the face to beg Li Xiaogong for forgiveness.
"Hmph~! Since Queen Tuigu wants to see me, I will go to the city! It just so happens that I also have something to tell her."
Li Xiaogong snorted and said immediately.
Ono Yoko was overjoyed, but Li Xiao next to him was shocked and said quickly: "Your Majesty, you must not do this~! If there is an ambush in the Japanese Imperial City, and you encounter any accidents, your subordinates will die~!"
