Datang's free and easy concubine

Chapter 1719 Propagation
Chang'an City has already curfew, but Duke Lu's Mansion, which was originally quiet, suddenly became noisy again.

Cheng Chumo led the guards excitedly into the Duke's Mansion, Cheng Chumo jumped off the horse and strode towards the inner courtyard. He has been out of the house to oversee the work these days and has not returned home, so he is really homesick.

Just when he walked into the backyard, Cheng Chumo raised his eyes and saw his father striding over.

After being away from home for so many days, I didn't expect my father to rush out to greet him personally when he heard the news of his return.

So moving!

It's not in vain that he has been exposed to the wind and sun for so many days!
After a while, Cheng Chumo suddenly realized that there seemed to be something wrong. Why was the old man still holding a wooden stick in his hand?
"Father, why are you still holding a stick in your hand? What are you going to do?" Cheng Chumo hurriedly stopped and asked in a daze.

He suddenly had a bad feeling.

"Well, you bastard, after returning to Chang'an, instead of going home to see my mother, you would go to Sleeping Flowers and Sleeping in Liu Xiaoyao to be happy? See how I will deal with you, you bastard today!" Cheng Yaojin shouted violently.

"What sleeping flowers and willows? Dad, I just returned to Chang'an! As soon as I entered the city, I went back to my residence!" Cheng Chumo yelled as he turned his head and ran away.

Cheng Yaojin shouted violently while chasing him: "Do you think your father is a fool? The city gates are closed, how did you enter the city? Can you still ask to open the city gate?"

"Of course I can't open the city gate, but Your Majesty can! I entered the city after His Majesty!" Cheng Chumo explained loudly.

"The more you talk, the more outrageous you are! You bastard is going back to the city, does His Majesty still go out of the city to welcome you?"

"Ouch! Ouch! Your Majesty and the Empress went to Sujiazhuang! Su Cheng made a generator that can produce lightning for lighting!"

"Su Cheng can create thunder and lightning! Why don't you say that Su Cheng can call wind and rain?"

"Father, it's true! Su Cheng really created lightning and used it for lighting! We all saw it! Yuchi Baolin, Li Chongyi, Li Zhen, Changsun Chong and the others saw it! If you don't believe me, just ask the boy!"

Cheng Yaojin called the boy over and asked, while Cheng Chumo stood beside him grinning in pain.

After asking for a while, Cheng Yaojin finally understood what happened.

"Su Cheng can really create lightning to illuminate?" Cheng Yaojin looked incredible.

Cheng Chu nodded silently and said: "Isn't it? We were all dumbfounded. The electric light is so bright that it can turn into a beam of light and can illuminate far away! Su Cheng specially made an electric light and intends to install it on the train for night lighting .”

"No, Dad, didn't you know that Su Cheng is making generators in Chang'an?"

Cheng Yaojin slapped his thigh and said angrily: "Su Cheng has been busy building railways, and he never sees the end. Who knew he would do such amazing things without making a sound!"

Cheng Chu said silently: "Father, now you know that I was wronged?"

Cheng Yaojin glared at him and said, "Can you blame me? Who told you not to say it earlier?"

Cheng Chumo stared innocently and said, "Why didn't I say that? You don't believe me!"

Cheng Yaojin said straightforwardly: "Nonsense, who will listen to what you tell and who will believe it?"

This sentence choked Cheng Chumo. After thinking about it carefully, he felt that what his father said was right, and he really couldn't blame him. No one would believe it if it happened to anyone.

Who is to blame?
If you want to blame, you can only blame Su Cheng!
"It's all Su Cheng's fault!" Cheng Chu mo grinned in pain.

Cheng Yaojin also nodded and said, "Yes, it's all Su Cheng's fault, no, you bastard, why didn't you work hard as a supervisor and came back?"

Cheng Chumo hurriedly said: "The railway construction is complete!"

Cheng Yaojin cried out in surprise after hearing this: "What? The railway has been built? Hahaha! You bastards have done a good job! The railway has been built, and Su Cheng didn't say when it will open to traffic?"

Cheng Chu shook his head silently and said: "I don't know, it seems quite troublesome to hear Su Cheng's meaning."

"The railway has been built, so where is the trouble? Forget about it." Cheng Yaojin waved his hand and said, "Tell me about the electric light first!"

While Cheng Chumo was spitting, Chang Sun Chong also walked into the study quickly.

Changsun Wuji raised his head and smiled, "Are you back?"

Changsun Chong nodded and said: "The construction of the railway is completed, so they are all back, but Su Cheng said that they need to test a few more times, and make sure that the railway and the train are safe before opening to traffic."

Changsun Wuji nodded slightly and said: "He is very thoughtful. The speed of the train is so fast, and it's okay to pull goods. If you pull so many people, you really have to be more cautious. How did you enter the city at this time?"

Chang Sun Chong explained: "Originally, we couldn't go back to the city tonight. We went to Sujiazhuang, but Su Cheng was experimenting with generators and electric lamps, making lightning for lighting. Your Majesty and the Empress also went to see the experiment. After watching the experiment, We will go back to the city with His Majesty and Empress Dowager."

It turned out that this was the case, Empress Changsun couldn't help but wondered when she heard it, and then he asked suspiciously: "Generator? Electric light? Make lightning for lighting? Are you right?"

Chang Sun Chong said with a smile: "It sounds unbelievable, but I saw it with my own eyes. However, it is not a spectacular scene like lightning and thunder, but a steam engine is used to drive a generator to run, and then a rubber-wrapped copper wire is used to transmit it to a On the glass lamp, the glass lamp will emit a dazzling light."

"That's the electric light, it's amazing and very bright, but Su Cheng can also gather the electric light together to form a beam of light, which is not only brighter but also can shine far away!"

"The reason why Su Cheng made electric lights is to install them on trains so that they can run at night..."

Chang Sun Chong described it carefully, and Chang Sun Wuji listened very carefully, and asked his doubts from time to time.

However, Chang Sun Chong couldn't answer most of the questions, because he didn't know much.

Changsun Wuji pondered for a while, still with an incredulous expression on his face, and said with emotion: "It's really amazing that Su Cheng can make lightning lighting!"

Changsun Chong nodded and said: "At first it sounds really miraculous, but Su Cheng said that thunder and lightning have nothing to do with gods, it's just a natural phenomenon. Moreover, it's not the big battle of lightning and thunder in the sky, it's just lighting up like a lamp."

Changsun Wuji slightly nodded and said, "Even if it's just to create a very small lightning, that's amazing. Who would have thought of lighting with lightning in the past and present? Don't even dare to think about it!"

"Besides, after listening to your description just now, the electric lights made by Su Cheng are very useful!"

"Su Cheng doesn't appear in the court these days. All the civil and military officials in the court thought he was busy building the railway. Who would have thought that he would turn out the electric light without making a sound!"
