Otaku Engineer in Great Tang Dynasty Chapter 731: Negotiation~!

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 the washing was too slow without the help of saponins!

The earliest ancients used plant ash as a stain remover, because it contains potassium carbonate, which can remove dirt on clothes. In addition, according to the "Kaogongji" record: practice silk, use the column as gray, shun the silk, realize all kinds of Zeqi, shake the mirage. The mirage in this sentence is shell ash, which contains calcium hydroxide, which is mixed with plant ash to produce potassium hydroxide. When it is immersed in water to wash silk fabrics, the oil attached to the surface of the silk fabrics chemically reacts to produce "potassium soap" , Can wash silk fabrics clean and bright.

Later, the ancients in the Wei and Jin dynasties began to use soap jade and bath beans to wash their clothes. The soap jade can generate foam in the water and have decontamination properties. Later, Sun Simiao invented a new method of washing clothes, that is, 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 well, and air dry in a ventilated place. It becomes a bath bean that can wash away clothes and dirt.

"Okay, I know~! But the military training is a special period, and the conditions will naturally be tougher. You don’t need to pay too much attention to it, as long as the clothes don’t smell bad! 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 reserve some places for shops, but he has been too busy and has not had time to "attract investment", so besides the cafeteria, there is basically no other place to spend money in the academy.

As for whether or not to make soap, it depends on whether he is in this mood.

"Yes, Shan Chang~! Students understand~!"

Jia Jiayin arched his hands and walked towards the dormitory.

Li Zexuan nodded secretly in his heart, saying that although this child looks a bit fierce, his character and knowledge are okay. As for men, they are still learning in the end. There are more celebrities who are ugly in ancient times but eventually stand out.

"Stand at attention~!"

After Jia Jiayin left, Li Zexuan shouted loudly, and then said: "Start standing in the army, Pang Feiji, you come to supervise them, whoever acts irregularly and is lazy in secret, give him extra time~! Understand~?"

Pang Feiji wiped the sweat from his forehead. There was a prince and two princes in it! Li Zexuan asked him to watch, isn't this killing him~?

"Huh~?"

"Yes~! I understand~!"

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

Li Zexuan nodded with satisfaction, and then said: "Yeah~! From tomorrow night, after Haishi, you and other instructors must check the dormitory one by one. If you find out who violates the discipline, the punishment is the same as today. No You are not allowed to sleep when you arrive, do you know~?"

"Yes~! The mountain is long~!"

Pang Feiji feels bitter~! They are actually quite tired as instructors during the day, but now that the draft is like this, their rest time is much less!

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

Thousands of miles away, Wa Country, Asuka is near the mountains outside the capital.

"My lord, the king of the Kingdom of Japan sent an envoy, and he is outside the camp. Would you like to see you~?"

The Chinese army's big account, Li Xiaogong was looking at the big map on the table, suddenly a messenger came in and bowed.

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

"No~!"

After a while, a short man in a Japanese suit came in and bowed to Li Xiaogong and said, "Yoko Ono has seen the Lord King~!"

This sentence can be spoken in extremely pure Chinese, and it also has a Guanzhong accent. Li Xiaogong raised his eyebrows and said: "Do you still speak Chinese~?"

Yoko Ono leaned slightly and said: "Central Plains culture is broad and profound, and the whole country admires the Japanese nation. I only rely on my father Yu Yin. He has studied in Central Plains for a period of time, so he 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 Yoko Ono's father, sister Ono.

In 609 AD, Sister Xiaoye came to China again as an envoy to the Sui Dynasty. And also brought a group of overseas students and monks studying abroad. Yoko Ono was in it at the time. Therefore, Yoko Ono knows a lot about the customs and culture of the Central Plains.

Li Xiaogong nodded slightly, and talked directly with a Japanese who can speak Chinese. He would feel more comfortable in his heart. After a while, he asked, "What did the Queen Tuigu send you over? Why didn't she come to see this king in person~ ?"

Arrogant!

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

"Go back to the prince, her dragon body is not good enough to go out of the palace. I hope the prince will understand~!"

Yoko Ono said slowly.

"Huh~! Inconvenience to go out of the palace~? Does she still want this king to go into the city to see her~?"

Li Xiaogong heard this, staring angrily.

Yoko Ono quickly made a look of sincerity and trepidation, and then said: "The lord, forgive me, she is really old. IndoMTL.com~ Recently, the dragon is in poor shape and really can't go out of the palace."

"How old is your age? How old~?"

Li Xiaogong asked a very rude question, but who made him strong? Wherever there is strength, it is an uncle, a weak country has no diplomacy, and a strong country has hegemony! This is a truth that can work in any era.

Yoko Ono's face is red, he gritted his teeth, and then said: "Going back to the prince, she has entered the ancient year this year~!"

(Sixty sixties, seventy years old and rare)

Li Xiaogong was actually not sure about the age of the Queen of the Kingdom of Japan. At this moment, after listening to him, he gave a surprised "Oh" and said, "That's it~! It seems that Queen Tui really wants this king to enter the city to see her. It~?"

When Yoko Ono heard the words, she was inexplicably excited, but she smiled flatteringly on her face: "When I came down, the saint said that if the prince is willing to condescend to enter the palace, he will definitely receive the most grand welcome from the country, the golden beauty At that time, the prince will definitely enjoy endlessly~!"

"Asshole~!"

Li Xiaogong patted the table, and said angrily: "Slacker, you dare to use it to charm this king~?"

"Yes, yes~! I said something wrong in the next, please let the prince atone for your sin~!"

Yoko Ono was very angry, but in fact, he kept slapping the face to ask Li Xiaogong for forgiveness.

"Huh~! Since Queen Tui wants to see this king, then this king will go to the city! It happens that this king has something to tell her."

Li Xiaogong "hum", then said.

Yoko Ono was overjoyed, but Li Xiao next to him was shocked, and quickly said: "My lord, don't do it~! If there is an ambush in the King City of Japan, if you encounter any accidents, your subordinates will die~! "
