It was a day close to November, the weather was already cold, the students rarely went out, Su Bai was copying books in the library, according to his current speed, he felt that if he wanted to write down all the books in the palace silently, he could write until death!

Su Bai was copying a book, he heard a sound behind him, and the sound of hurried footsteps sounded behind him, Su Bai looked back, and saw a 'swarthy' student running over, stained with a lot of ashes, Su Bai knew at a glance that this was coal dust.

Just as Su Bai was wondering if this student had gone to dig coal, he saw this student running to his side with an excited face, panting and saying, "Wait for the master!" Waiting! Run, run! ”

Su Bai was a little confused when he heard this, grabbed the warm tea in front of him and handed it to the other party: "Drink saliva, say it slowly, what did you run?" ”

The student didn't say anything polite to Su Bai, he took it and drank it all, and after drinking all the tea, he seemed to have recovered a little physical strength, and after taking two deep breaths, he said to Su Bai: "Waiting master, the steam engine, you can run with wheels!" ”

Su Baiteng stood up on the stool immediately, and didn't ask the student anything more, just ran out!

He couldn't help but be excited! He knew all too well what this invention meant! It's something that can change history!

When Su Bai ran to Suzaku Academy, he saw that there was smoke in the courtyard, and he could hear the sound of metal rubbing, and when he walked into the courtyard, he saw a mini locomotive more than one meter high, whining in the courtyard!

The rails below it are a circle, surrounding most of the yard, and the small train turns around the tracks. Next to him was a group of students from Suzaku Academy, running in circles with the small locomotive, and they were not too tired.

Su Bai finally understood why the student who went to inform him was covered in coal dust, and all the students of Vermilion Bird Academy were like this now, and when they saw that the train was running slowly, they threw coal into the stove.

When Su Bai saw this scene, tears flowed down instantly!

No one can understand his current mood, in the Tang Dynasty thousands of years ago, looking at things in the future world, that kind of mood cannot be described.

No one noticed Su Bai, and everyone's eyes were on the small train emitting black smoke and white water vapor. Only the student who went to Su Bai at the same time, when he caught up, what he saw was Wushuang Hou's face that had already been occupied by tears.

The student jumped, thinking that the coal smoke had reached Hou Ye's eyes, and hurriedly ran over and said, "Don't burn, don't burn, don't you see the smoke to Hou Ye?" ”

The students looked in the direction of his finger, didn't they, Su Bai was standing not far away, looking at him with red eyes. Several students were startled and hurriedly began to turn off the fire, and Su Bai said at this time: "No, no, don't do it, keep burning, I want to watch it run for a while"

The students all heard the slight tremor in Su Bai's voice, but they all thought that this was Su Bai's excitement when he saw the little train.

After hearing Su Bai's instructions, the students became even more capable and excitedly demonstrated to Su Bai.

This first-generation small train can be said to be a problem, but it can't hide the shining points on its body, looking at the small train in front of him, which is only one meter high, Su Bai can already see what the Tang Dynasty will be like in ten or twenty years!

Now with the steam engine, you have your own capital, trains, ships, everything!

"Hey, hey, master, how about it, I didn't disappoint you."

When Su Bai was distracted, a laugh came from behind him, and when he looked back, he saw Lu Yuan, the little guy, looking at Su Bai with a dark face, and when he saw Su Bai looking at him, he gave Su Bai a smile and leaked a mouthful of small white teeth.

Under the backdrop of the black face, the teeth are exceptionally white, and if it is night, it will definitely make people mistakenly think that whose teeth are sperm and float out by themselves~

Su Bai was a little distracted, and then heard Lu Yuan continue: "This train can run, I am a great contributor!" ”

Su Bai became interested when he heard this, and couldn't help asking, "Oh? How do you take the most credit? Say it and listen to it, if it's true, the master will reward you well! ”

As soon as Lu Yuan heard this, his eyes lit up instantly, and he stared at Su Bai with cute eyes and said, "What the master said is true?" ”

Su Bai raised his hand and gave him a violent shudder, deliberately pretending to be dissatisfied: "What words! Did the master lie to you? ”

Lu Yuan thought about it very seriously, and then nodded affirmatively: "Yes!" ”

Su Bai almost didn't come up in one breath, and said in disbelief: "When did I lie to you?" The little guy said indignantly: "The last time I took the exam, the master said that if I got into the top three, I would let me go out with Mingzhu for a day, but I took the first place in the exam, and you didn't let me take Mingzhu out to play!" What else is it dangerous for children to go out! ”

Su Bai's old face turned red, he no longer looked at Lu Yuan, and turned his head to continue to look at the little train.

Lu Yuan didn't seem to see that the master didn't want to mention this topic, and continued to say on the side: "This is the master of Ju County!" Who dares to hurt us both in Ju County! Who doesn't know that Mingzhu is your heart's top meat! ”

Lu Yuan was still talking endlessly, and Su Bai automatically filtered it, and now he was not thinking about these trivial things!

Lu Yuan didn't care, and continued: "I actually had a concept of this steam engine a few days ago, but there was a little problem with the seal, the seal was not heat-proof, the heat-proof was not sealed, and then I could only get to a blacksmith whose technology can be called the world's top technology as early as possible to try to seal, fortunately, we are now successful."

After Lu Yuan finished speaking, he glanced up at Su Bai, and saw that Su Bai was still looking at the little train, he didn't care, and continued to bow his head and said: "Then it is the conversion of heat energy into kinetic energy, fortunately, there is your drawing, this step is not too difficult for us, after experimenting with the opportunity, we made this thing you call the little train!" Master, can it change Datang? Train, train! A car that can walk with fire! How many cows and horses are left! ”

Su Bai glanced at his favorite third disciple, he was smart and smart, but after all, he was shallow! What he was thinking about now was how to leave the cow horsepower, but Su Bai was already thinking about how to get Li Shimin to agree to him laying the railroad tracks! Running through the north and south!

If Datang's railway network is built, distance will no longer be a problem!

The train finally stopped, and there were two or three thousand people on the outskirts of Suzaku-in! After they all heard the news, they came to see the excitement, and at this time, Wang Qincai, a teacher from Vermilion Bird Academy, walked up to Su Bai and said with an excited expression on his face: "Waiting for the master!" It's done! ”

Su Bai smiled and patted him on the shoulder and said, "Very good!" You've worked hard these days, take a good rest! ”

"To be able to do things for Hou Ye, Wang Qin is not hard!"

Wang Qin's voice was very loud, he could see that he was very excited, Su Bai also understood his current mood, Su Bai smiled: "Have a good rest, in two days, there is still a big job waiting for you!" ”

Hearing that there was still a big job, Wang Qin's eyes lit up, and he now said to Su Bai that he really admires it!

Not to mention anything else, the drawings of this steam train are waiting for them, they are not fake, but the drawings are given to others, and others can also be manufactured, it is nothing more than the reason of time.

Now Hou Ye said that there is still a big job waiting for him, what strange things will be built this time?

After Su Bai saw this train, he couldn't hold back his excitement a little, and shouted without looking back: "Yuan Hong!" ”

"In!"

"Go to the Prince's Mansion to deliver a message, and let His Royal Highness the Crown Prince make sure to come to Juxian County in the next two days!"

"Yes!"

Su Bai turned his head and glanced at the people behind him, there were two or three thousand people, and it was definitely a very unreliable thing to hide the news, but forget it, there was nothing to hide about this kind of thing, and even Su Bai was thinking, should I take the initiative to publicize this matter!

Su Bai checked the small train, and it was really rough, and many places were just simply welded. Some people may ask, in ancient times, there were no electric welding machines, how did they weld? In fact, it is very simple, the current brazing is actually a transformation of ancient welding.

Su Bai carefully checked the steam engine again and made sure that he would not explode due to excessive pressure before leaving.

On that day, all those who participated in this experiment received 200 credits! Those who have made significant contributions and outstanding contributions will be rewarded with 300 credits! If you go to exchange it for money, this is a few hundred taels of silver!

In an instant, Suzaku-in Temple became a sea of songs and laughter!

……

As soon as it got dark at night, Yuan Hong had already arrived outside the gate of the Chang'an Prince's Mansion!

"Two brothers! Please also report it, just say that Wushuang is waiting for the house, Yuan Hong asks to see! ”

Outside the prince's mansion, Yuan Hong turned over and dismounted, and said to the two guards at the door. Who doesn't know the relationship between Wushuang Hou and the Prince's Mansion? The two guards didn't say much, one went in to report, and the other led Yuan Hong directly inside!

Yuan Hong also knew through Su Bai's tone of voice that this matter was really anxious, so he was not polite at the moment, and directly followed the guards into the prince's mansion.

Every time Su Bai came to the Prince's Mansion, Li Chengqian would come out to greet him, and Yuan Hong naturally didn't have this identity.

Honestly walked into the room, Li Chengqian was sitting on a chair, and Ji Da was sitting opposite, and the two were drinking tea and chatting.

After seeing Yuan Hong come in, Ji Da gave him a big smile, he also knew that this was Wushuanghou's henchman, so he naturally didn't dare to offend.

Li Chengqian turned his head, and when he saw that it was Yuan Hong, he smiled and said, "What's the matter, Yuan Hong?" Come to the palace at night, do you have anything to worry about? ”

Yuan Hong clasped his hands into fists and saluted: "My family asked me to come to the Prince's Mansion to deliver a message, and I also ask His Royal Highness the Crown Prince to go to Juxian County in the next two days!" ”

Yuan Hong learned ten percent of Su Bai's tone at that time, and Li Chengqian couldn't help but be stunned after hearing it, but he also knew that if there was nothing important, Su Bai would definitely not let him go to Ju County! And it's so urgent!

Li Chengqian thought for a while and asked, "Do you know what the matter is?" ”

Yuan Hong thought for a while, and then said with some uncertainty: "Your Highness, before I came to the Prince's Mansion, my grandfather invented a car."

"A kind of car?"

Li Chengqian asked with some doubts, Yuan Hong didn't care who made the train, in his opinion, all this was his own grandfather!

Hearing the prince ask himself, Yuan Hong nodded and said: "That's right, that car is very strange, you can walk without a cow horse, it sprays black smoke and white gas, it looks a little scary"

As soon as Li Chengqian heard it, he came to his senses, what is it, without cattle and horses, and still emitting black smoke and white gas?

Li Chengqian turned his head to look at Ji Da, but Ji Da shook his head and said, "Your Highness, the students don't know either."

Li Chengqian thought for a while, looked at Yuan Hongdao, and said: "Go back and tell Wushuang Hou that within two days, this palace will definitely go to Ju County!" ”

"Yes!"

Yuan Hong agreed, and was about to retreat with his hands in fists, but Li Chengqian stopped him and took out a handkerchief in his arms. Then he took out his prince's seal and stamped it on it, and said: "It's curfew now, if you meet a soldier who stops you, you can show them this seal, so as not to cause trouble."

After Yuan Hong thanked Li Chengqian, he turned around and left.

……

The next day, just after the end of the morning dynasty, Li Shimin was having breakfast with the queen, when he heard the little eunuch outside the door whispering: "Your Majesty, see you at His Royal Highness the Prince"

"Cheng Qian?"

Empress Eldest Sun asked some questions, Li Shimin thought about it, and understood what Li Chengqian was doing here, and ordered softly: "Let him in"

"Yes"

The little eunuch agreed, and walked out of the hall backwards, and it didn't take long for a steady footstep to come, and then Li Chengqian walked into the hall outside the door, and saluted: "The son sees the father and the queen mother!" ”

Empress Changsun smiled and said, "Qian'er, come over and eat some together."

Li Chengqian raised his eyes and glanced at Li Shimin, and saw that Li Shimin did not say anything, so he walked closer, and the little eunuch on the side took a soft pier and asked Li Chengqian to sit down.

The family ate quietly, and the eldest grandson queen kept serving vegetables to the two, all of which the other party liked to eat.

"Going to Juxian?"

Li Shimin was the first to ask, Li Chengqian was not surprised, what he knew, if his father didn't know, then he would be surprised.

Li Chengqian didn't intend to hide anything, nodded lightly, and then picked up a pair of chopsticks and put them in his bowl, eating very happily.

Li Shimin continued to ask: "Go see the train?" ”

"Trains?"

Li Chengqian also questioned that he really didn't know what train was, and Yuan Hong didn't tell him.

Seeing Li Chengqian's appearance, Li Shimin knew that Li Chengqian probably didn't know anything now. Sure enough, when I looked at Li Chengqian again, I saw the curiosity on his face. Li Shimin actually had a feeling of pride, and said after coughing lightly: "That Wushuang Hou invented a kind of train, as long as the fire is burned, it can move forward."

Li Shimin said it very plainly, in fact, he didn't even understand what the use of that train was......
