Otaku Engineer in Great Tang Dynasty

　　 "Get married~?"

　　 After hearing Li Zexuan say that Mo Lingwei wanted to get married, Yan Shaoning couldn't help but froze, and fell silent.

People are not grass and trees, who can be ruthless, Mo Lingwei’s friendship with him, no matter how low his EQ, he can still feel it, but the happiness that everyone usually gets along with is a pleasure, but when it comes to talking about marriage, this Yan Shaoning It was a little difficult to accept for a while, or that he hadn't turned his mind and was not prepared for it!

Seeing this, Li Zexuan frowned slightly and said, "Shao Ning, do you want to lose Miss Mo? Although Miss Mo shouts to you on weekdays, she never allows others to say bad things about you behind her back. Her friendship is visible to everyone. If you lose her, I, the first brother to despise you!"

Yan Shaoning hurriedly waved his hand and said: "No! How dare I take her? I...I'm just worried that if I marry her, depending on her temperament, I won't be bullied by her every day? And his father is so high in martial arts, Not even under your martial arts in Xiaoxuan, she bullied me, if I fight back or even talk back, her father knows, he can't tear me up~?"

　　 Li Zexuan couldn't help but look stunned after hearing this. The old man is too powerful, has it become the reason why you dare not get married? This is to let Mo Huai know. Surely he will come and kill you now?

　　 "The normal girl Mo bullies you, Shaoning, do you dare to fight back?"

　　 After a moment of silence, Li Zexuan asked aloud.

　　 Yan Shaoning was startled, and then replied: "I... a good man doesn't fight with women. How can Yan Shaoning be a man of seven feet like a woman?"

　　Li Zexuan smiled and asked: "Then if you change a girl and bully you like Miss Mo, would you be happy?"

Yan Shaoning stared and said: "Xiaoxuan, what are you talking about? Other women have never known me, how could they bully me for no reason? Besides, I am not a masochist. Listen to you, who I still have to bear the anger? Let me tell you, then no! But! Yes!"

At this moment, Li Zexuan smiled with his palm: "Then sum up what you just said in one sentence is that you are being bullied by Girl Mo. You are willing to be bullied by other women, and you are unwilling. If this is the case, then Shaoning you still hesitate. What? Hurry up and get married with Miss Mo! Otherwise, if your father and his elders take photos of other famous ladies in your life, wouldn't you be reluctant to do so in your life~?"

Yan Shaoning was stunned. Although he felt that there might be something wrong with Li Zexuan's words, he couldn't find a point to refute for a while. On the contrary, he still vaguely felt that Li Zexuan's words were so reasonable. Seeing Li Zexuan staring at him, Yan Shaoning After a moment of silence, he said dullly:

　　 "The truth is such a truth, then I'll go back and discuss with my father, let him go to propose to Mr. Mo!"

　　 "Haha! That's right! Shaoning, I will definitely give you a gift when I wait for your wedding day, brother!"

　　 Li Zexuan laughed when he heard the words.

In public for private, emotional and rational, he is happy to see Yan Shaoning and Mo Lingwei walking together, and the two are fans of the authorities and bystanders. Although they love each other, if others don’t say anything to wake up, I don’t know. When will they come together!

　　 Although Mo Lingwei's personality is a bit domineering, this is exactly when Zhou Yu hit Huang Gai, one willing to fight and the other to suffer!

　　 Yan Shaoning's eyes were a little dazed, so he stood there in a daze, Li Zexuan patted him on the shoulder, and then smiled and walked forward.

　　 "Eh! No! Xiaoxuan! Why do I have to be bullied? I can..."

　　………………………………

　　 "Haha! Wang Er is here! Everyone play him!"

　　 "Yes, yes! Splash him! Who let him come the latest?"

　　 "Ah! No! My mother didn't let me play in the water. I waited for a long time before sneaking out!"

　　 "Haha! Don't care! Everyone splash him!"

In the evening, Li Zexuan accompanied Han Yuxi on a walk in the fields. The setting sun went down. As the cement ditches in Lantian County were all filled with water, children could be seen playing in the ditches everywhere. Seeing this scene, Li Zexuan could not help but remember his previous life. When I was a child, every summer, the farmland in the village needed to be pumped and irrigated. The water channel in the village happened to pass in front of his house, and he often played water with his friends in the channel. , Of course, playing in the water is cool for a while, after playing, you will be beaten when you go home!

　　 "Hehe! Lady, guess if these children go home wet after a while, will they be beaten?"

　　 Looking at the scenes in front of him, Li Zexuan's mouth made a smile, and then he said regretfully to Han Yu beside him.

　　 There is more gloating in the words!

　　 As a pillow, how could Han Yuxi fail to hear Li Zexuan's tone of gloating? She glared at Li Zexuan and said, "Msang-song, these children go back and get beaten, how do you feel that you are still happy?"

　　 "Hey! The lady is really smart!"

Li Zexuan squeezed Han Yuxi’s little hand and smiled: “This is always fair. Some people work hard when they are young, and they won’t suffer and suffer in their old age. When they are young, they only know how to eat, drink and have fun. When you are old, you can only suffer and get tired! In the same way, these bear kids are now playing in the ditch. When they return, they will naturally have to kneel and be beaten!"

　　 "Punch~!"

　　 Han Yuxi heard the words and couldn't help but "pushed" and said with a smile: "Sang Gong, you are purely perverted. If children play in the water, how can you still be unfairly related to God?"

　　Li Zexuan smiled, and then said solemnly: "Of course it is fair to the heavens. It is because of my husband who has been single for more than ten years that I have earned such a beautiful lady!"

　　Han Yuxi's cheeks are reddish, and she can't help but yell: "My husband, you are talking nonsense! Let's go back soon! Don't make mother and father wait in a hurry~!"

　　 They have now moved from Yunshan Courtyard back to Houfu in Lantian County. Yunshan Courtyard is only here when something goes wrong, and occasionally stays here. Usually they will live in the county seat!

　　 "Okay! Go back!"

　　………………………………

　　There is water, electricity, and electric lights. The next step is to start using electric lights on a small scale in Yanhuang Academy!

In the previous experiment on the bank of the Bahe River, four of the ten bulbs were exploded. The four bulbs that exploded were all because the resistance of the filament was too small, and a large amount of heat accumulated in the bulb in a very short time. , It will explode naturally!

　　 Li Zexuan later recorded the technical parameters of the bulb with stable brightness and asked the workshop to produce a batch of bulbs of this specification.

At the same time, the gentlemen of the Physics Department of Yanhuang Academy have recently been explaining courses on electricity safety to students at intervals. The purpose is to prevent students from appearing due to improper use of electricity when electric lights are promoted to the academy. Danger to life!

　　 At the same time, on the side of the road from the bank of the Bahe River to the Yanhuang Academy, electric poles made of concrete and steel bars were erected. After the poles were erected, the wires were erected!

　　 Speaking of this wire, it is really a hassle!

Although Yunshan is less than three miles away from the Bahe Hydropower Station, it is less than three miles away. The copper core in the photoelectric line weighs more than 2,000 catties when the wires are installed, because it involves "long-distance" power transmission. You must not use that very thin copper wire, you must use thick copper wire!

　　 Two thousand kilograms of good brass, and just connecting Yunshan to a place, so much brass is needed, which makes Li Zexuan couldn't help being one head two big! You must know that brass in this era can be regarded as a kind of "precious metal", and its main purpose is to mint coins! Just to get more than two thousand catties of brass, Li Zexuan spent a lot of time, because there are basically no merchants outside who have the ability to get such a huge amount of brass!

　　 You must know that from Xia, Shang, Zhou and Han, bronzes have always been a symbol of the status of emperors and princes. After the Han Dynasty, with the progress and development of social economy and trade, the currency value of copper coins became prominent, and the amount of copper used surged. China is a copper-poor country, so it was difficult to find copper in ancient times. The production and use of copper have a great impact on society. Copper produced in the Han, Tang, Song and other dynasties was an important source of government revenue. For this reason, in this era, copper is regarded as a strategic material controlled by the state. Not only do ordinary people do not need bronze, it is even more impossible to get a thousand catties of brass!

　　 The Tang Dynasty not only prohibited private mining of copper mines, but also prohibited private merchants and craftsmen from making copper ware. But because copperware is still loved by people in daily life, it is profitable to make copperware. "Old Tang Book" records, "Today, south of the Jianghuai River, there are many bronze wares, and the market is chasing profit. The sales can be counted as a tool, and the profit is three or four times. The remote people do not know the laws and regulations. Why is the supply and marketing of money making money? So the ban on copper has to be strict." "Every one thousand dollars sold is six catties of copper, and the creation of miscellaneous objects is more than six thousand catties. The benefits are thick and the sales are numerous."

The general idea is that the profit of destroying copper coins to make copper ware can reach three to six times. The money made from six catties of copper is worth one thousand, while the value of making utensils can be sold for six thousand. Do business of ruining money maker.

It can be seen that in this era, brass is not only a rare thing, but also a noble thing. It is impossible for folks to take out a thousand catties of brass. Even if someone can take it out, he cannot use this expensive brass. Go make the wires!

Although Li Zexuan could throw all the two thousand catties of copper coins into the furnace to recast, he did not do that, because he felt that doing so was disrespect for the currency itself, and destroying the copper coins privately would violate the law in the Tang Dynasty. He doesn't want to hold on to political opponents!

　　 In the end, Li Zexuan had no choice but to go to the palace to see Li Er and ask for brass!

　　Because he remembers that when the Japanese delegation visited Li Er, he once donated tens of thousands of catties of brass. Now Li Er, there is definitely no shortage of copper in his hands!

At first, Li Er heard Li Zexuan’s intentions, and of course he was unwilling to give it. But Li Zexuan said at the time: "Your Majesty, Datang has now fully used Tang Yuan, and the demand for copper coins will decrease year by year. Datang produces every year. The brass should be used in the right way! You know, the best conductive thing in the world, except silver, is copper! It is the most wise choice to use copper as the wire to transmit electricity!

　　Furthermore, the minister previously provided drawings of the waterwheel to save the people in Guanzhong from the deep waters. He has done a great job. As a generation of saints, your majesty will naturally have merits and rewards, and he will be punished! The minister does not ask for other rewards, but only asks your majesty to reward him with 10,000 catties of brass! "

In the end, Li Zexuan's boasting and shameless means of asking for rewards made Li Er pleased. Old Li angrily scolded Li Zexuan, and then drove the latter out of the palace. However, Li Zexuan returned to the Hou Mansion. Before long, the servants in the palace came to the Hou Mansion to declare the decree. The content of the decree was to commend Li Zexuan for his contribution to the waterwheel some time ago. There was no increase in officials or no rank, but Li Zexuan was rewarded with five thousand catties of brass!

　　 After listening to this wonderful imperial decree, Father Li and Ye Guozhong all stared roundly, and they couldn't laugh or cry for a while!

Li Zexuan was like a treasure. Although Lao Li didn't give 10,000 catties of brass, he only gave 5,000 catties of brass, but 5,000 catties was enough. He had asked Li Er in the palace to ask for 10,000 catties of brass. Li Zexuan was already quite satisfied with Li Zexuan’s big mouth, leaving a lot of "bargaining space."

　　With brass, the next step is to make wires!

The outer ring of the wire needs to be wrapped with a layer of insulating material. In modern times, the insulating material outside the wire is made of PVC plastic. The composition is polyvinyl chloride. It is monomers such as ethylene and acrylic acid obtained through the cracking of petroleum, and then through polymerization and other chemicals. The reaction is obtained.

　　 Although it is easy to find petroleum in Datang~www.ltnovel.com~, the technology to decompose petroleum is not fully available at present, so Li Zexuan directly uses rubber as the insulation layer of the wire!

　　 He had used this method before, but before, they were all experimental wires, which didn't cost much rubber, but now these three-mile wires require a huge amount of rubber, and Li Zexuan, who is rich and powerful, can't help but feel distressed! Mainly this rubber is too hard to get!

　　 If these rubbers are used to make footballs, the footballs made will definitely sell for tens of thousands!

　　 At this time, Li Zexuan realized that in order to promote the use of electricity in Datang, technology is a very important aspect, and raw materials are also very, very important! Must be self-sufficient!

　　If you blindly rely on "imports", it will not only cause a sharp increase in costs, but also make it easy for others to choke one's throat, which Li Zexuan is very unwilling to see!

　　 "Prepare the horse! I'm going to Chang'an!"

　　 Thinking of the source of the rubber, a person suddenly appeared in Li Zexuan's mind, and he quickly ordered Liu Feng and Liu Yun behind him.

　　 In the future, he will definitely organize elite forces in academies and workshops to overcome difficulties and refine oil, but rubber must be self-sufficient, and he must grasp both!

　　 "Yes! Lord Hou!"
