Bring The System To Datang

After the meal, the people went to various places.

Li Yi took a pen to copy medical books, copying and learning.

Pei Yaoqing also sat at the desk, thinking about things, taking notes from time to time.

Li Chengqi fiddled with the light bulb and the pedal generator. He found that the light bulb was not bright when the speed was slow.

As he speeds up and slows down gradually, the brightness of the bulb changes together, and when a lot of power is applied, the bulb maintains a constant brightness.

"What is the reason?" Li Chengqi wanted to figure out the principle between the speed and the brightness of the bulb.

Then from the outside, the window of the room he was in was flickering and flickering, which was a bit scary.

In the room next to the yard where Li Longji was, someone was riding the pedal of the bicycle and connected to Li Longji's study.

The palace sent him the memorial handed in today's political affairs hall. Gao Lishi simply approved it and sent it to Zhuangzi without making up his mind.

Li Longji enjoys the benefits of electric lights, and the people in the next room need to rotate.

"It's better than a candle." Li Longji found that the light hanging in front of his head didn't shake, it was always bright.

The Queen couldn't sleep, so she strolled slowly in the room and chatted with Tao Hong.

There is also a light bulb in her bedroom, covered with a frame of red gauze, and the light coming out is warm.

"Taohong, what do you think if this lamp is used by wealthy people?" Queen Wang looked up, avoiding the light again.

"Someone will be punished for kicking and kicking. If they can't kick or light up, they will be beaten." Tao Hong saw the person kicking outside the room.

There are cast iron gears and chains in Zhuangzi, and there is a chair to sit on, and the kicker's legs are not fast.

When changing to someone else’s house, I can’t bear to use good iron for gears. According to the proprietor, the gears can’t be used once they turn.

Queen Wang was full of bright heart. When she heard Tao Hong's words, Bai gave her a look: "I didn't tell you to kick, the people of the world feel distressed?"

"Isn't it the same in the palace?" Tao Hong pouted.

"Don't be afraid, look at what Uncle does. The windmill does not turn from time to time. He can't let the farmer run on and generate electricity all day."

Queen Wang looked as if I was not in a hurry, wait.

Zhuangzi gave a new method and took it back to the palace.

Right now... continue to be kicked.

"Take things home tomorrow, and send a set to Baifudian, the others..." The Queen stopped.

"I heard that people in several palaces have complained." Tao Hong revealed the news.

"Sabur is here with me, of course they quit, they almost made Zhao Lifei's son Li Ying the crown prince, which is very risky."

Queen Wang was very upset about this.

There are too many women, all kinds of concubines, Zhaoyi, Jieyu, and talented people.

"Queen, you have to come to Zhuangzi every three to five times. Only when you get to Zhuangzi, your majesty will not take other people, unless you are ill and too medically inadequate."

Tao Hong gives an idea.

"Will not take others?" Queen Wang was not sure.

"The proprietor said that the wretched wife will not go down in court. Your Majesty will take other women. The proprietor promises not to give a good face." Tao Hong explained her analysis.

"Okay, Uncle people are good." Queen Wang issued a card, as long as she can stabilize her position, it is a good person.

***

The good guy Li Yi copied it very carefully. He checked every page he copied, but he didn't dare to make any typos.

After writing an hour, Li Yi stopped and copied these today.

He looked up at the light bulb. The dealer insisted on coming over to generate electricity manually. Li Yi didn't succeed in stopping it, so he left the dealer to exercise there.

"When wind power and hydropower cannot form a unit, the current and voltage are unstable.

Hydroelectric power generation is okay under supersaturation, but there are not rivers everywhere.

There is lead, and it is very pure, there is also green alum oil, yes, it is dilute sulfuric acid. "

Li Yi thought of lead-acid batteries. Lead has long existed and its purity is high.

Dilute sulfuric acid must be admired by Master Pill Refining, who refines all kinds of things, adds things in, takes out a chemical reaction, and takes them out for people to eat. It's a lot of metal.

"After the Chinese New Year, it's cold, I can live a lot, I can't be too busy." Li Yi muttered and shouted to the outside: "Sleep."

"Proprietor, I'm going back." Swish, with the sound, the light went out.

The next morning, the people who had eaten all left in a rush.

Li Longji brought three sets of human generators, a large box of light bulbs, the light bulbs were not used for carrying, and there was no tungsten wire.

Li Chengqi brought five groups and said that he was helping Yi brother to test. Li Yi said that I believed in your... evil.

Pei Yaoqing took a set. He wanted to do propaganda, asking the rich to watch it first, and then do it himself.

Get free light bulbs from Li Yi, and you will have to pay for using light bulbs after the new year.

As they left, skaters arrived, and it was most convenient for those who lived in Zhangjia Village last night.

"Dongzhu Li, give me another look. The one who jumps up and turns in a circle, I think I can do it by looking at me." Someone shouted to Li Yi.

"I can't." Li Yi always felt uncomfortable with his right ankle as soon as he heard the jump and circle, and firmly refused.

Turn around and go for a walk to digest food, and then go to teach the students for half a day.

When Li Longji went back there, he was entangled by the three prime ministers.

The dynasty did not open this morning, and all the various departments and officials need to say are in Yao Chong's hands.

"What is the thing that your majesty brought back today?" Yao Chong asked curiously first without mentioning official duties.

"Uh..." Li Longji was in trouble, he brought less, and the Zhengshitang should have a set.

"For things similar to candles, I will use them for you first, and then give them to the Zhengshitang." Li Longji made an excuse.

The three prime ministers looked at each other and felt so sad.

"Your Majesty, the marriage of Turks..." Yao Chong said.

"No, in the future, anyone who wants to marry me in the Tang Dynasty will only allow foreign daughters to enter the Tang, but not Tang women to marry outside." Li Longji gave the answer.

"Why?" Yao Chong asked.

"The mountains are high and the road is far away. It's very difficult to meet each other. I don't want to let the princess go outside to endure hardship." Li Longji looked like I was a good father.

The three prime ministers look at each other again, can they have such reasons? Your Majesty, the princess you promised others is not yours, right?

The early Princess Wencheng was a distant relative.

Princess Jincheng, who is in Tubo, is the daughter of Li Shouli.

Are you reluctant to let go of someone else's daughter? Oh my!

Li Longji didn't want to explain, and said to three people: "People with Tubo and Turkic border markets, regardless of whether they are private markets, are not allowed to take out the Datang equipment. No craftsman can.

The good technology wants to stay in Datang, stop it once it can stop it, and tell them to learn it, isn't it because they have money and food to come and beat us. "

When the prime ministers listened, they instantly understood why they didn't marry out. Every time they married a princess, they had to bring craftsmen and technology with them.

"The officials understand." Yao Chong agreed.

He also feels uncomfortable giving good things to him, being careful.

The queen on the other side went to Baifudian and gave a set of things.

Three sets, one set in her place, one set in the office of His Majesty, and the last set for the Supreme Emperor.

Others didn't, even the well-loved Wu Jieyu, who was good at singing and dancing, and pleasing to people.

As soon as Queen Wang and the team arrived at Baifudian, Concubine Doulu took her hand to sit down and talk.

"Queen, you can't travel too fast in the palace, you must be careful." Concubine Doulu glanced at the queen's belly and said.

"I know, today I was anxious to give you good things, now they all know, huh?"

Queen Wang asked about her pregnancy. She kept it from her, but she couldn't keep it from her.

"I don't know if it's a man or a woman." Concubine Doulu told Queen Wang that others could only guess.

"I don't eat food from the palace, nor do I drink any medicine. I'm not afraid." The Queen said grinningly.

Concubine Doulu was a little relieved, after listening to the own man, Zhuangzi's Li Yi's medical skills were extremely good.

She knew that only when the Queen Wang was in a stable position could she feel at ease, and Li Dan was also safe.

Concubine Doulu doesn't know the history, but she can feel it.
