I am engaged in construction in Datang

The newspaper was in turmoil, and the women in the village...

Maybe quiet?

"Come on, open your mouth, ah——" Li Yin was wearing a white coat, a mask, and a bright bronze mirror on her head.

The sun is shining brightly today. Xiaoxia is lighting candles opposite, and everyone is trying their best to ensure sufficient light.

She coaxed Fang Xuanling to open his mouth as if she was coaxing a child.

Then he put the forceps into his mouth, and with his other hand holding a bamboo stick, he pried Fang Xuanling's mouth open and turned it back and forth inside.

"Uh, ah..." Fang Xuanling felt the movement in his mouth and retched a little.

"Duke Liang, your premolar is badly damaged." Li Yin clamped the tooth on the lower right side with pliers, moved it back and forth, and told Fang Xuanling which one it was.

"Ouch, be gentle, be gentle." Fang Xuanling couldn't bear it anymore and started to cry out: "My tooth always hurts, and stuffing elm bark into it doesn't help."

"Of course it won't work. The damage you've done is quite deep." Li Yin put down the tools in her hands and began to prepare drill bits, hammers and other things.

"This... is it time to pull it out?" Fang Xuanling was a little scared.

He wanted to get his teeth fixed when he had toothache before, but now that it doesn’t hurt anymore, he doesn’t have the courage to do so.

Every time he passed by a dentist's shop, he could always hear heart-wrenching wails. He even went in to take a look, but all he saw was a bloody mouth, so he hurried out in fear.

"It doesn't have to be removed. I need to see how deep the damage is." Li Yin comforted the old man: "Don't be afraid, I've given you anesthesia. If it doesn't work, I'll give you some wine."

Li Yin obtained the formula of Hua Tuo's Ma Fei San from the system, which included both drinkable and compressive formulations. According to the system's instructions, she gave some to Fang Xuanling to drink and also applied it on his gums, taking a two-pronged approach.

It’s not as good as the anesthetics of later generations, but the effect is pretty good.

Plus with the silver needles blocking the senses, there shouldn't be any big problems.

Fang Xuanling felt that the place on his shoulder where Li Yin had patted him started to grow hair, and then he felt the roots of his teeth start to ache and itch, as if they were covered with sesame seeds.

"I won't pull it out anymore, I won't pull it out anymore!" Fang Xuanling was scared.

He lifted the white cloth on his body and was about to leave.

"Hold him down!" Li Yin was shocked and blurted out.

Good man, we have already put you here and prepared everything, how can we ask you to run away?

Zhao Erniu moved quickly and grabbed Fang Xuanling's shoulders, while Xiaosong and Xiaoyang secured him.

Then several people took out strips of cloth and tied Fang Xuanling to the treatment bed.

Li Yin picked up the fallen white cloth and covered it.

This was to prevent saliva from staining his clothes, but in Fang Xuanling's eyes, it looked like he was covering his head.

Fang Xuanling accepted his fate and glanced over, seeing Li Shimin and others walking towards him in the distance.

He was supposed to hold a government meeting today, but he had an appointment with Master Li to get his teeth fixed, so he asked for leave and did not go.

Hey!

Unexpectedly, I met him at the village.

So Fang Xuanling stopped howling, it was too embarrassing.

"Sister-in-law!" Li Shimin saw a group of people gathered in a circle under the scorching sun from a distance and thought that something new had happened.

"Brother!"

Hearing Li Shimin's voice, the surrounding tenants spontaneously made way for him.

Then, Li Shimin and his companions looked at Fang Xuanling from afar with tearful eyes.

Fang Xuanling: "..."

"..."Li Shimin, Wei Zheng and others.

"Brother, I'm repairing Duke Liang's teeth!" Li Yin looked excited, holding an awl in his left hand and a hammer in his right hand, and strode over.

"Um……"

"Very good." Li Shimin looked at Fang Xuanling again and felt that today was not the right time to come.

"Xiaosong, hurry up and get the brothers' toothbrushes."

Li Yin instructed Li Xiaosong, then turned to look at Li Shimin and the others: "Brother, ask me to show you guys later."

Looking at Li Yin's sparkling eyes, Li Shimin couldn't say no.

I deceived myself into thinking that my stepsister was a great doctor!

I just like to play a little.

Li Shimin took a few people to brush their teeth, and the tenants over there surrounded Fang Xuanling again.

He turned his head to take a look, and felt that Fang Aiqing was going to be torn into pieces and swallowed in the next moment.

Without external interference, Li Yin began to repair Fang Xuanling's teeth.

"Duke Liang, how do you feel?"

"Shut up, shut up..." Fang Xuanling was in a daze, and the Ma Fei San began to take effect.

"Q——!" Li Yin said something that only she understood, and others thought it was an interjection.

She smiled and said, "I'll seal a few more acupuncture points on you."

A quarter of an hour later.

"Duke Liang?"

"..." Fang Xuanling was already confused.

Half an hour later, Li Yin wiped the sweat from her forehead.

"Fortunately, no nerves were damaged." If no nerves were damaged, there was no need to extract it.

"Steel sheet." Li Yin said to Xiaoxia. It is used to circle the teeth, so that you can apply ointment to shape them later.

It was two hours later when Fang Xuanling woke up.

"Awake?" Li Yin took out the plaster and said, "Come and bite it, and I'll wrap your teeth in gold."

Fang Xuanling was still confused. He turned his head and saw a fat man lying next to him.

Turning around again, I saw the faces of Li Yin, Li Shimin and others.

Then he woke up.

"I... am okay?" He spoke with a lisp and his gums were swollen.

"It's almost done." Li Yin said. It has to be covered with gold, otherwise it will be bad for the body if it comes into contact with the silver paste for a long time.

"Hey, it doesn't hurt!" Fang Xuanling said again. It's just that his gums are swollen, which is acceptable.

So he bit the plaster, and someone in the village took it away to make gold braces. There was only one person like him, so there was no need to wait.

Not long after, Xiao Yu, who was lying over there, also woke up.

The Duke of Song's mansion was wealthy, and Xiao Yu was old and loved sweets, so his teeth were the worst damaged. On the other side, Li Shimin and his companions were not in any trouble.

After working for a while, everyone except the two dentists finally got to eat.

I made rice rolls, salty porridge and milk-flavored steamed buns. The steamed buns were only half the size of an egg and were very enjoyable to eat one at a time.

The bowl for porridge is also small, about the size of a palm.

If you don’t want to eat salty porridge, you can eat steamed dumplings and mung bean soup to cool down and quench your thirst.

Li Shimin picked up a small steamed bun with a milky flavor and stuffed the whole thing into his mouth. He also ate a piece of cold cucumber and drank a mouthful of porridge. He felt comfortable.

"Sister, now more than 700 students who are studying for the second-class certificate have returned home, but from the news I got, the spread is not going smoothly. What should I do?"

Li Yin put down the bowl of soup and said, "If we wait for two months, everyone will see the benefits of the biogas digester and will definitely follow suit."

"Plus, the weather is good now, and the first batch of ponds will be put into use in late July or early August. In this way, the people who follow suit will also be able to enjoy the benefits of biogas this winter."

“So, my brother is worried about the remote areas that are not well-informed and cannot catch up with the biogas digesters this winter.”

Li Shimin nodded. His sister understood him: "The people in the south are fine. I am worried about the people in the north."

Even if someone brings a team to build it, what if everyone doesn’t believe it?

Or what if everyone believes it but has no money to build it?

Li Shimin never worried about how the rich would survive the winter. What he worried about was the poor people who could not afford charcoal.

"This problem is easy to solve." Li Yin drank the salty soup in the bowl in one gulp. If she didn't drink it, it would get cold!

"Brother, the most difficult thing is not asking the people to build biogas digesters, but what should the people who make a living by selling firewood and charcoal do after the biogas digesters are built?"

“When new or old technologies are innovated, the common people may not be the first to benefit, but they will definitely be the ones who suffer.”
