Prince Chenda nodded: "Isn't it Arabic numerals?" Recognize. ”

Leng Qinghuan vaguely remembered that Arabic numerals were introduced to China around the 8th century AD, with Buddhism, but they were not accepted, and then, at the end of the Ming Dynasty and the beginning of the Qing Dynasty, Western mathematical works were introduced to China, and they were not popularized, and the earliest use was in the first year of Guangxu.

The dynasty in which I am now belongs to the air, and there is no record in history, but the people already have the writings of the Ming Dynasty, and the palace has also initially set up an internal affairs office, responsible for the emperor's household affairs, and it is not uncommon for Arabic numerals to be introduced.

Therefore, she was not too surprised, and just asked casually: "Is Mobei already using these numbers?" ”

"No, my Mobei's culture is mainly due to the spread of Chang'an, these numbers I learned from Lord Lu, he said that it is a unique script in his hometown, how can the princess also know it?"

Lord Lu? Leng Qinghuan naturally knew that on that day at the post station, he was the personal butler of Prince Yuda, taking care of Chenda's diet and daily life, and he was silent on weekdays, not a talkative person.

Leng Qinghuan sighed: "I saw a strange-looking missionary before, and he taught me." ”

"Prince Ben still thinks that you and Lord Lu may be fellow villagers." Prince Chenda said nonchalantly: "I know so many strange and unheard things. ”

Leng Qinghuan didn't take it to heart, and Prince Chenda didn't ask any more questions, turned his face away, and continued to talk with Murong Qi, proposing to see Murong Qi's riding and archery skills and horse kung fu.

Murong Qi said two words to himself, and someone from outside came in to reply, saying that King Xuan had sent an invitation, and tomorrow he would invite Prince Chenda to hunt in the royal hunting ground, and several princes would be invited together.

He couldn't ask for it, so he immediately agreed happily.

The periphery of the royal hunting grounds is full of captive-bred herbivorous prey such as elk and antelope, which are used by the children of the royal family to practice riding and archery kung fu and relieve boredom, and there is no danger. Only in the depths of the hunting ground, Yishan took advantage of the situation to isolate a lion and tiger camp alone, and a few fierce beasts were raised in it.

Prince Chenda sincerely invited Leng Qinghuan to come along.

Qing Huan is now bulky, and it is inconvenient to participate in such an occasion, and he only has greed for the sake of go, so he politely refused.

The next morning, Murong Qi and Prince Chenda got up early, and without alarming Leng Qinghuan, they got on their horses, brought bows and arrows, and set off in high spirits.

Leng Qinghuan slept until three o'clock in the morning, then got up, packed up the food box, and went to the palace with his pocket.

At the last banquet for Prince Chenda, the Queen Mother didn't seem to have a good appetite, and she sat upright, didn't eat, and frowned.

Leng Qinghuan asked, only to know that the Queen Mother had a toothache, and she could only eat some liquid food and very soft things. Qing Huan checked it, and his gums were inflamed, and even his cheeks were swollen.

She took a few painkillers and anti-inflammatory drugs for the Queen Mother, and she could only wait until the inflammation completely subsided before she could pull out the tooth.

As the saying goes, a toothache is not a disease, it hurts to be fatal, but the ancients should not do anything about this toothache, and the imperial doctors in the hospital do not disdain to study this "carving insect skill". That's why there is a Qingqi painting style in the Spring and Autumn Period in which Qi Jinggong tied his teeth with a rope and bent over to his youngest son as a bull rider to try to extract his teeth.

This tooth decay has long made the Queen Mother unbearable, as long as it is on fire, her teeth hurt, and she can't eat for several days and can't sleep well. Listening to Leng Qinghuan say that it can be pulled out and eliminated forever, she was very heroic at that time, even if Leng Qinghuan knocked it down with a hammer, she was willing.

Leng Qinghuan entered the palace, the Queen Mother's toothache was already cured, it didn't hurt anymore, it was a little better, the scar forgot the pain, and asked Leng Qinghuan how to pull out this tooth? Is it a rope, or an arrow, or a pinched with a pair of pliers? Will it be like Mr. Wen Qiao, a famous general in the Eastern Jin Dynasty, who had dental disease to extract teeth, which caused a stroke and hung up in less than 10 days?

Leng Qinghuan was originally just a half-ass, only theoretical knowledge, no practice, but the Queen Mother's tooth has been loosened, and sooner or later it will fall out, and she can suffer less if she is extracted.

After a few words of consolation, the Queen Mother also made up her mind. Leng Qinghuan disinfected, anesthetized, and then took the tooth extraction pliers and pondered how to start.

When Lu Wu heard that she had entered the palace, she came over to join in the fun, and asked casually: "My brothers went hunting today, why didn't you follow?" ”

The medicine has already come up, the queen mother opened her mouth widely, Leng Qinghuan changed the angle, and the tooth tongs were doubled, and she hesitated to get down.

A group of big men, fighting and killing, what kind of fun am I following? You can only be greedy. ”

Besides, isn't this ball in the stomach in the way?

"Jinyu is gone, why can't you go?"

Leng Qinghuan "chuckled" in his heart: "Jinyu also went?" ”

"Yes," Luwu asked rhetorically, "you don't know?" ”

Of course I don't know, but if I did, how could I be here to study tooth extraction like no one else?

According to the customs of Chang'an, a prospective newlyweds to be married should not meet with the man. What did King Xuan invite her to join in?

You must know that Jin Yu is a troublemaker, and now at such an important juncture, in order to avoid harmony, the dog jumped off the wall in a hurry, and any means can be used.

He told Murong Qi to stay away from Jinyu, so as not to give her an opportunity to take advantage of it, so that she could rely on it. Today, Jin Yu actually went hunting with him, which is clearly wrong!

How could she have the leisure to go hunting? I'm not in the mood to contact Prince Chenda.

There was a tremor under his hand, and the Queen Mother's tooth was simply and rudely pulled out.

A ball of hemostatic cotton was stuffed into the root of the tooth, and then the medicine box was packed in a hurry.

"Bite the hemostatic cotton ball tightly and spit it out after half an hour. Then you can drink water and eat after an hour, and do not eat too hot and spicy food. Do not rinse your mouth for two days, and do not lick the socket with the tip of your tongue. ”

She told her like a broken bean, and the Queen Mother was still a little confused: "It's already pulled?" Why don't I hurt? ”

"Don't worry, after a while, the numbing will pass, and it will hurt."

The Queen Mother grinned with a rhombic mirror, feeling uncomfortable: "I'm old, my teeth are about to fall out, and I want to eat meat." ”

"It's okay, I'll find a way to put dentures for you when I go back, the peanuts and beans can be chewed fragrantly, and they look good." Leng Qinghuan picked up the food box: "It suddenly occurred to me that there is still something in the house, Grandmother Huang, I will go back first." I'll see you in two days. ”

"What's the hurry? Since I came, I ate and then left. ”

"You can't eat now, can you sit and watch me eat? Another day, another day. ”

"Are the dentures you said reliable?" The Queen Mother seemed to suddenly remember something, and was obviously very interested: "Can this still be faked?" ”

Leng Qinghuan was in a hurry to leave, and he didn't have time to explain, so he agreed: "I'll go back and ponder, and I promise to be able to confuse the real with the fake." ”

He didn't knock his head, and hurriedly went out of the palace with his pocket.

The Queen Mother kept chasing out: "This girl, what are you doing in a hurry?" I still have important things to ask. Hiss, it hurts a little. ”
