After hearing Jia Jiayin's words, Li Zexuan suddenly realized that he was still wondering why these students were still washing clothes at this point, it turned out that it was because there was no soap horn to help wash it too slowly!

The earliest ancients used plant ash as a stain remover because it contained potassium carbonate, which could remove dirt from clothes. In addition, according to the record of the "Examination of the Work": practice silk, take the column as ash, Wu Chun its silk, real Zhuze device, shake the mirage. The mirage in this sentence is shell ash, which contains calcium hydroxide, mixed with plant ash, can generate potassium hydroxide, and when it is immersed in water to wash silk fabrics, it reacts chemically with the oil attached to the surface of silk fabrics to produce "potassium soap", which can wash silk fabrics clean and bright.

Subsequently, the ancients in the Wei and Jin dynasties began to use soap horn and bath beans to make clothes, and soaphorn can produce foam in water and have the property of decontamination. Later, Sun Simiao invented a new method of washing clothes, which is to wash the dirty blood on the pig's pancreas, tear off the fatty liver on it and grind it into a paste, add soybean flour and spices, stir evenly, and after the ventilation is air-dried, it becomes a bath bean that can wash away the dirt of clothes.

"Okay, I got it~! However, military training belongs to a special period, and the conditions will naturally be difficult, so you don't have to pay too much attention to it, as long as the clothes don't stink! After the military training, there will be everything in the academy~! ”

Li Zexuan said lightly.

At the beginning of the construction of the academy, he did leave some places for shops, but he had been too busy and had not had time to engage in "investment promotion", so there was basically no other place to spend money in the academy except for the canteen.

As for whether he makes soap or not, it depends on whether he is in the mood or not.

"Yes, Mountain Chief~! Students get it~! ”

Jia Jiayin arched his hand and walked towards the dormitory.

Li Zexuan nodded secretly in his heart, and said in his heart that although this kid looks a little vicious, his temperament and knowledge are okay. Men, in the end, they still rely on their talents, and there are more celebrities who were ugly in ancient times but eventually got ahead.

"Lizheng~!"

After Jia Jiayin left, Li Zexuan yelled loudly, and then said: "Start standing in a military posture, Pang Feiji, you come to supervise them, whoever moves irregularly and is secretly lazy, give him overtime~!" Do you understand~? ”

Pang Feiji wiped the sweat from his forehead, there is a prince and two princes here! Li Zexuan asked him to keep an eye on him, didn't he want his old life~?

"Huh~?"

"Yes~! I understand~! ”

Under Li Zexuan's pressure, Pang Feiji hurriedly agreed.

Li Zexuan nodded with satisfaction, and then said, "Hmm~!" Starting tomorrow night, after the end of the day, you and other instructors must go by dormitory to find out who violates discipline, just like today's punishment method, you are not allowed to sleep when you are not in the child, you know~? ”

"Yes~! Mountain Chief~! ”

Pang Feiji is bitter~! They are actually quite tired from being instructors during the day, but now that they are drafted, they have a lot less time to rest!

............................

Thousands of miles away, the country of Wa, the acres of mountains outside the capital of flying birds.

"Lord, the king of the Wa Kingdom sent a messenger here, and now he is outside the camp, do you want to see it~?"

In the big tent of the Chinese army, Li Xiaogong was looking at the big map on the table, when suddenly a herald came in and bowed.

Li Xiaogong raised his head and said lightly: "Let him come in~!" ”

"No~!"

After a while, a short man in a Japanese suit walked in, bent down and saluted Li Xiaogong: "Yoko Ono has seen His Excellency the Emperor~!" ”

This sentence can be said in extremely pure Chinese, and with a Guanzhong accent, Li Xiaogong raised his eyebrows and said: "You can still speak Chinese~?" ”

Yoko Ono bowed slightly and said: "The Central Plains culture is broad and profound, and the whole country admires it very much, and I just rely on my father Yu Yin, and I have studied in the Central Plains for a period of time, so I can speak some Chinese~!" ”

In 607 AD, the first Japanese government mission to the Sui Dynasty of China finally arrived in Luoyang, and the head of the mission was Yoko Ono's father, Sister Ono.

In 609 A.D., Ono Meizi came to China again as an envoy to send the Sui envoy back to China. And also brought a group of international students and overseas monks. Yoko Ono was also among them at the time. Therefore, for the customs and culture of the Central Plains, Yoko Ono knows a lot about it.

Li Xiaogong nodded slightly, and directly communicated with a Japanese man who could speak Chinese, his heart would be somewhat comfortable, and after a while, he asked, "What did Queen Tuigu send you over~?" Why didn't she come to see the king in person~? ”

Arrogant!

It can be said that Li Xiaogong's attitude is extremely arrogant! But Yoko Ono's face only changed slightly, and she didn't dare to make any rebuttals at all.

"Back to the prince, the saint is in poor health and it is inconvenient to leave the palace, I hope the prince will understand~!"

Yoko Ono said slowly.

"Hmph~! It's inconvenient to go out of the palace~? Does she still want this king to go into the city to see her in person~? ”

When Li Xiaogong heard this, he glared and said angrily.

Yoko Ono hurriedly made a look of sincere fear, bowed down and said: "The prince forgives the sin, it is really the saint that she is old, and she has been in poor health recently, so she really can't leave the palace." ”

"Old? How old is it~? ”

Li Xiaogong asked a very rude question, but who made him strong! Where there is strength, it is a master, a weak country has no diplomacy, and a strong country has hegemony! This is a truth that can be put in any era.

Yoko Ono's face was red, he gritted his teeth, and then said: "Back to the prince, she has entered the year of ancient rarity this year~!" ”

(Sixty sixtieth flowers, seventy ancient rare)

Li Xiaogong actually didn't know the age of the Queen of the Japanese Kingdom, but after hearing it at this moment, he let out an "oh" in surprise, and then said: "I see~!" It seems that Queen Tuigu really wants this king to enter the city to see her~? ”

When Yoko Ono heard this, she was inexplicably excited, but she smiled flatteringly: "When I came down, the saint said that if the prince is willing to deign to enter the palace to see him, he will definitely get the most grand welcome from the Japanese country, and the golden beauty will inevitably make the prince enjoy it inexhaustibly~!" ”

"Bastard~!"

Li Xiaogong slapped the table and said angrily: "Cheap girl in the lower country, dare to use it to charm this king~?" ”

"Yes, yes~! It's a mistake to say the wrong thing, and please atone for the prince~! ”

Yoko Ono was angry in his heart, but in fact he kept slapping him in the face to beg Lee Hyo-gyong for forgiveness.

"Hmph~! Since Queen Tuigu wants to see this king, then this king will go to the city! It just so happened that this king also had something to say to her. ”

Li Xiaogong "snorted" and then said.

Yoko Ono was overjoyed, but Li Xiao next to him was shocked, and hurriedly said: "Lord, don't do it~!" If there is an ambush in the city of the king, if you encounter any more accidents, your subordinates will die~! ”
