One Piece of Song Dynasty

Liang Hongyu asked: "Sir, why does that glass ball become brighter?"

Li Xin replied: "Madam, that's because it can light up because of electricity."

Li Jing asked: "Brother, what is electricity?"

Li Xin asked back: "Have you two seen thunder on a rainy day?"

The two women nodded and said, "I've seen it before."

Li Xin said: "That is electricity. Electricity has always been around us, but it is invisible and intangible. Of course, we cannot touch it. There are still things like thunder and death on rainy days."

Liang Hongyu asked: "Officer, what is the use of doing this experiment? We can neither see nor touch electricity, so what use is it to us?"

Li Xin replied: "This experiment at least proves the existence of electricity. There are still many things we don't know around us. We should not be afraid of these unknown things, but should also take the initiative to explore and understand them." Unknown things, they may be of great help to our lives, such as this electricity. Madam, you asked what the use of electricity is. Let me tell you, the most basic use of this electricity is for lighting. Now it lights us up at night. They all use candles. When we have a larger and more stable generator in the future, we can no longer use candles and just use light bulbs for lighting. Electric lighting is much brighter than candles. By then we will The scenery you see at night will be much more beautiful than it is now.”

Liang Hongyu imagined it for a while and said, "The Nu family still can't imagine what the beautiful scenery the officials said is like. I really want to see it soon."

Li Xin nodded and said, "Madam, don't worry, you will see it soon."

Li Jing asked: "Brother, how do you know so much? Why haven't I seen you talk about it before?"

Li Xin smiled and said: "Don't say it, don't say it. Just know that your brother and I didn't invent this. I also learned it from others."

Li Jing said: "Okay, brother, then I can usually look at these things with these Confucian scholars."

Li Xin replied: "Of course, my sister is also interested in these."

Li Jing nodded and said, "Well, I think it's quite fun."

Li Xin said: "Okay, since you are literate anyway, you should be able to understand their books. If you have any questions, please come to me or ask others for advice."

Li Jing replied: "Yes, brother, I understand."

After the test, Li Xin stepped forward and said, "Zhao Xi, you did a good job. I will give you both a reward of ten taels of silver later."

Zhao Xi, Liang and Peng clasped their fists and said, "Thank you, lord."

Li Xin then said to the Confucian scholars: "Everyone, you must not only learn thoroughly the knowledge in those books, but also study it more deeply. The knowledge in the books is only a small part of the known knowledge, and there are more. There is so much knowledge waiting for us to discover.”

The Confucian scholars replied: "Yes, Lord, we all understand."

Li Xin continued: "When you do experiments, you can do them in several related subjects together, such as physics, chemistry, metallurgy, and arithmetic. Some aspects of these subjects are interoperable. This time Zhao Xi and Liang Peng will do it. Very good, one of them is studying physics and the other is studying metallurgy. The two of them collaborated to make a generator to prove the existence of electricity. I hope this kind of thing can happen more often in the future, and I will give you a reward every time it happens."

All the Confucian scholars clasped their fists and said, "Yes, Lord."

Li Xin and Zhao Xi said: "Now that the existence of electricity has been proven, I hope you will continue your efforts to build a bigger and better generator as soon as possible, so that electricity can truly enter our lives. Of course, it depends on you two alone." It’s not enough, as someone just said, we need to unite more people to do it together.”

Zhao Xi replied: "Yes, lord, we will not let you down."

The discovery of electricity can be said to have brought Xinghan Island into a new page. With Li Xin's speech, the enthusiasm of the Confucian scholars was once again mobilized. Several discoveries will be made on Xinghan Island in the following period.

Li Xin, who returned to his home, thought about it for a while. The life of a light bulb made of bamboo silk was only more than forty hours, which was still too short. Tungsten was also needed, and tungsten was used for more than just light bulbs, including national defense, energy, health, materials, etc. It has important uses in many aspects, but in this era, no one knows about tungsten ore, only you know it.

There are many tungsten ores in China in Jiangxi. Li Xin thought for a while and wrote down the specific shape of the tungsten ores, and then sent it to the housekeeper Li An and asked the housekeeper to collect the ores. Of course, in addition to the tungsten ores, Li Xin also wrote down the details of the tungsten ores. The two other rare metal ores found are lead and zinc mines in Jiangxi and manganese mines in Fujian. The other ores can only wait until later. These rare metal ores can be said to be picked up for free and no one wants them. It is collected good times.

In the blink of an eye, time entered September, and on this day Emperor Tianzuo came to Nanjing with his children and ministers.

After Niu San saw Emperor Tianzuo and others, he ran back to the mansion and reported to Liang Xinghui: "Mr. Lang, Emperor Tianzuo has come to Nanjing. I saw him on the roadside just now."

Liang Xing stood up and said, "Oh, are you sure?"

Niu San replied: "I'm sure, the main road is guarded by Liao soldiers. I saw the guard of honor of the brigade entering the city. With such a large formation, I guess it's Emperor Tianzuo."

Liang Xing nodded and said: "Okay, you send someone to wait in the tunnel. If Emperor Tian Zuo is really coming, those two eunuchs will definitely send us a message. When they see those two eunuchs, they will come and notify someone."

Niu San cupped his fists and said, "Yes, Langjun."

At night, Niu San sent a message: "Lang Jun, Xiao Dezi is waiting for you in the tunnel."

Liang Xing said: "It seems that Emperor Tianzuo is really here. Let's go to the tunnel."

Liang Xing and Niu San entered the tunnel together and saw Xiao Dezi at the end of the tunnel: "How about it? Emperor Tian Zuo is here with his family."

Xiao Dezi said: "To tell you the truth, it was Emperor Tian Zuo who entered the imperial city with his family members and ministers."

Liang Xing said: "Okay, you go back and tell Xiao Shunzi that in the past two or three days you have to find out where Tianzuo Emperor Princess Yelu Yuliyan lives, as well as the security situation around her residence, or what she does every day. , will go somewhere often.”

Xiao Dezi replied: "Yes, sir, I understand."

Liang Xing ordered: "After we have found out everything, come to the tunnel at midnight and report. In the past few days, someone will be sent to wait in the tunnel at night."

Xiao Dezi nodded and said: "Yes, sir, I understand. I must have found out everything about the eldest princess."

Liang Xing patted Xiao Dezi and said, "Do your best. After this is accomplished, you two will be rewarded heavily."

Xiao Dezi clasped his fists and said, "Yes, sir. I would like to thank you first."
