Seeing a group of people busy, Ye Mengqiu leaned over to Li Hao's side and asked in a low voice, "Lord Wang, these two ...... What is it? ”

Li Hao pointed to these two things respectively and said, "The one on the left is a steam locomotive, and the one on the right is a steam engine." ”

Ye Mengqiu still looked at Li Hao with a confused expression, it was obvious that he didn't understand what a steam engine was, let alone what a steam locomotive was.

Seeing that he didn't understand, Li Hao thought about it and explained, "Cows and horses know. ”

"Yes." Ye Mengqiu nodded.

Li Hao said: "This steam engine is equivalent to a cow and a horse. ”

Ye Mengqiu's face was dazed, it was obvious that he didn't think that these steel things had anything in common with cattle and horses.

Li Hao continued: "Let me ask you, what is the use of cattle and horses? ”

Ye Mengqiu said: "Cattle can plow the fields, they can pull carts, horses can be used as mounts, and they can also pull carts. ”

Li Hao said: "That's it, the steam engine can carry people, can also pull the car, see that the car is not, the car is a car powered by a steam engine, the cow and horse run for a long time, will be tired, but the steam engine will not, as long as there is fuel, the steam engine can keep moving." ”

Ye Mengqiu's brain is still very flexible, thinking about Li Hao's words carefully, the more he thinks about it, the more surprised he becomes, the more shocked he becomes, a car that can sail indefinitely, what a magical thing.

At this time, Li Hao said again: "The steam engine belongs to the power source, which can provide power for all machinery, of course, there is no machinery yet, there will be in the future, my big ships know it, if a large steam engine is built, it can also be installed on my big ships, when the time comes, my ship will sail faster, and it is not limited by wind force and wind direction, and you can go wherever you want." ”

Li Hao's words had completely shocked Ye Mengqiu, Ye Mengqiu looked at the steam engine in disbelief, and couldn't believe that this strange machine was so powerful.

Soon, the fire in the furnace of the steam engine was whirring, the white steam was spraying outward, the steam engine slowly rotated, Ye Mengqiu saw the steam engine turning, and immediately frowned and asked, "That's it?" ”

Li Hao smiled: "Don't underestimate this rotation, if you install a track, link other machines, you can drive other machines to rotate, all the machines, have a circular motion as the starting point, and then the effect into other power, you will look at the steam locomotive, see if the steam engine can drive this car." ”

The steam locomotive is a bit big, and the steam engine installed on it is also a bit big, so the preheating is a little slow, and after a while, the steam engine wheel on the steam locomotive rotates, and the track drives some of the wheel axles of the car to rotate, Cheng Qingyun sat on the car, and pulled the gear lever hard, and suddenly the car went forward, the speed was not very fast, but it really moved.

Cheng Qingyun began to turn the steering wheel, and the car suddenly began to turn, and after turning in one direction, he walked happily in the backyard.

Cheng Qingyun was dumbfounded, in his impression, no matter what kind of car, either animal power or manpower, otherwise it would not be able to move at all, but this steam locomotive is so magical, it can move just by constantly spraying steam, and the speed is not slower than that of horse-drawn carts and ox carts.

After a long time, Cheng Qingyun drove the steam locomotive back to Li Hao, got off the car and saluted Li Hao, and asked, "The student is ugly, and I ask the teacher for guidance." ”

Li Hao smiled and said: "What else can I point out about, even if it is for the teacher, you can't build this steam engine and steam locomotive, you really didn't disappoint the teacher!" Attaboy! ”

Cheng Qingyun was praised by Li Hao, and he was so happy that he said: "Teacher, we have built a larger generator, and the power storage technology has also been improved, and now the entire school classroom is equipped with electric lights, oh, by the way, now the electric lights have also been improved, the filament is thin enough, the smallest electric lamp, the power is 100 watts, and the voltage is also stable at 220 volts." ”

"Hmm." Li Hao nodded with satisfaction and asked, "When can I power up my villa?" ”

Cheng Qingyun said with a smile: "Before this summer, the students are already planning to start erecting power poles, the electricity generated by this generator should be enough for your villa, but it is impossible to want more, after all, the river is too small, the power is not big enough, and the students have done their best." ”

"It's okay." Li Hao smiled and raised his eyebrows, "Don't we have a steam engine now, as long as we build a huge steam engine, build a huge generator, and use the steam engine to drive the generator, isn't this enough?" ”

"That's what the teacher said." Cheng Qingyun smiled and nodded, "The students think the same way, but the students have a budget, and I'm afraid it will take 100,000 yuan." ”

Li Hao said: "If you are short of money, even if you go to Chang'an to find Shi Najie to ask for it, I have greeted him for the teacher, how much you want, how much he will give." ”

"Thank you!" Cheng Qingyun was extremely excited.

Next, Cheng Qingyun took Li Hao to visit the classroom, and sure enough, there were electric lights in each classroom, although now the sun has set, twilight is approaching, and the classroom is dim, but as long as the light wire is turned on and off, the lights are on, and the whole classroom is bright, Wu Lei and Ye Mengqiu are magical.

Seeing so many classrooms equipped with electric lights in Datang, Li Hao's heart warmed, he was in the countryside when he was a child, the conditions were poor at that time, his primary school was the kind of old-fashioned brick house, the ground in the classroom was dirt, and the lights in the classroom were all ordinary incandescent lamps, similar to these bulbs in front of him, such a scene reminded him of his primary school days.

Looking at the dazzling lights, Li Hao was so excited, he did it, he really did it, the steam engine appeared, alternating current has become a climate, it only needs to be promoted on a large scale, it can be used throughout the country, this world, because of his arrival, has completely changed, how can he not be excited.

"Shall I ...... Tell Li Shimin...... "Li Hao stood alone in the corner and whispered to himself.

If you want to promote science, the best way is to get the emperor's help, that will be the supreme help, Li Hao pondered for a long time, and finally decided to report the matter to Li Shimin, so he turned around and walked outside the classroom, and said loudly: "Go!" Back to the lodge! ”

Li Hao returned to the villa, went straight to the study, and began to write the note, the content of the note is relatively simple, just a general introduction to the magic of the steam engine and electric light, his purpose is to let Li Shimin come to see it in person, because these things cannot be moved to the Taiji Palace.

Early the next morning, Li Hao took the song to the Taiji Palace, Li Shimin was in the Ganlu Hall and Li Zhi together to review the song, when he heard that Li Hao asked to face the saint, Li Shimin was very happy, and immediately announced the meeting.

Li Hao entered the Ganlu Palace, stood still in the center of the hall, saw that Li Zhi was also present, and greeted him with eyebrows and eyes, he couldn't help but smile, and then saluted: "Minister Li Hao See the emperor, see His Royal Highness the Prince." ”

"Poetry is not polite." Li Shimin smiled and waved his hand and asked, "Is it a good thing or a bad thing to come to see me so early in the morning?" ”

Li Hao raised his head and smiled: "Your Majesty, the minister has brought great news to Your Majesty. ”

"Oh?" Li Shimin raised his eyebrows when he heard this, he still knows Li Hao very well, although Li Hao is public, but he is very realistic when offering treasures, and he can be called a lot of good news or good things, but the good news is the first time to hear Li Hao say, so Li Shimin smiled and asked, "Good news, how good?" Is it better than Zhenguan rice? ”

Li Hao smiled and said, "It's more than that." ”

"Really?" Li Shimin was a little overwhelmed when he heard this, and hurriedly said, "What good news, come quickly." ”

Li Hao held the music with both hands, and Xu Lian hurriedly went down to hand it over and sent it to Li Shimin.

Li Shimin opened it and beckoned to Li Zhi: "Zhi'er come and see." ”

"Yes, Father." Li Zhi hurriedly walked over to him and watched together.

After reading it, Li Shimin looked at Li Hao with strange eyes, and asked suspiciously: "Is there really such a magical car in the world, it can move itself without oxen and horses, or manpower?" ”

"Back to Your Majesty, yes."

"And that electric light." Li Zhi asked excitedly, "You don't need to add oil to light the fire, it will light up as soon as it is turned on, and the brightness is comparable to that of thousands of oil lamps?" Really? ”

"Back to His Royal Highness the Prince, yes."

"You're not deceiving me, are you?" Li Shimin was still incredulous, and said, "How can there be such an incredible thing in the world? ”

Li Hao said: "Your Majesty might as well move to see, hearing is false, seeing is believing." ”

"Hmm......" Li Shimin pondered for a moment when he heard this, and suddenly turned his head to Xu Lian and said, "Xu Lian, prepare for driving, I want to go to Lantian to see if what King Qiongnan said is true." ”

"Yes." Xu Lian hurriedly went to prepare.

Soon, Luan drove ready, five horses driven, Hua umbrella palace fan, thirty palace maids, thirty attendants, ten imperial doctors, ten vehicles, two hundred Jin Wuwei, one thousand Yulin army, the team battle was huge, and the mighty march out of Chengtianmen.

Li Shimin left the palace, the movement was naturally not small, and the ministers came to stop and inquire after hearing about it, after all, it is not a trivial matter for the emperor to leave the palace, if there is no legitimate reason, the ministers can dissuade him.

Even if Li Shimin showed Li Hao's recital to the ministers, those ministers didn't believe it after reading it, shouting that Li Hao's bewitching words confused the public, bullying the king, and weaving a series of charges against Li Hao, Li Hao looked at this group of ignorant ministers and shouted like clowns jumping off the beam, just standing there laughing and silent.

After they finished shouting, Li Hao smiled lightly: "Everyone, even if Li is a bully, do you have to wait until Your Majesty goes to see it before you can convict Li?" ”

The ministers were stunned when they heard this, and then they all shouted: "Okay, I'll accompany the holy driver to see your magic car and magic lamp, and when the time comes, see how you lie!" ”

So, a large number of courtiers joined the team and went to Lantian together.

Because the team was too large, when they arrived at Lantian, it was already evening, and when Li Hao took them into the school, twilight fell, and the whole school was pitch black.

Standing on the playground in front of the teaching building, Li Hao suddenly shouted: "Turn on the lights!" ”

Suddenly, the lights in all the classrooms of the entire school were turned on, because there was a person standing in each classroom, who was responsible for turning on the lights, and the ministers and Li Shimin were suddenly dumbfounded, and they didn't know what to say.

Li Hao shouted again: "Turn off the lights!" ”

In an instant, the lights in all the classrooms went out, and the surroundings returned to a state of darkness.

"Turn on the lights!" Li Hao shouted again, and the lights in all the classrooms turned on again.

"Turn off the lights!"

"Turn on the lights!"

……

Li Hao asked people to turn on the lights and turn off the lights over and over again, all the classrooms were brightly lit for a while, and it was dark for a while, and the ministers were all standing there in a daze, they felt that they had been slapped in the face by Li Hao, and they were beaten very hard.
