Otaku Engineer in Great Tang Dynasty Chapter 1152: Bonus? punishment!

　　"This is the fireworks?"

　　 On the edge of the playground, Li Erxing stood beside Li Zexuan. He looked up at the splendid fireworks in the sky. The color of surprise in his eyes was fleeting. Although he is the emperor of the world, he is such a dreamy and magnificent spectacle. It's the first time I saw it! He could not help muttering to himself.

　　 Seeing this, Li Zexuan couldn't help feeling a little proud. He could shock Li Er, a famous emperor, how many people in the world could do it?

　　 But while he was proud, his eyes were still very vigilantly watching the students in the field who ran to light the fireworks. After all, this thing exploded to people, and the consequences are still very serious, so he You must always pay attention and be prepared to save people!

　　"Yong'anhou, how can these fireworks soar to the sky quickly?"

　　 Suddenly, Li Er asked such a "Xiao Bai" question. It seems that the sky has a very powerful attraction to the ancients!

　　 "Your Majesty, Qingque should know this question, let him explain it to you!"

　　 Li Zexuan arched his hands and said.

　　"Oh? Do you know the reason for the blue bird?"

　　 Li Tai, who was standing on Li Er's left hand, stood up excitedly upon hearing this, and replied:

　　"Father, as far as I know, the reason why this firework can quickly rush into the sky is related to the gunpowder in it! Once the gunpowder explodes, it will generate a very powerful thrust to make the firework The projectile part overcomes its own gravity and quickly flies into the sky!

　　 And the upper end of the projectile, its fuze was ignited when it flew out of the pipe. The length of this fuze was calculated by the length of the mountain, so it can be guaranteed to fly to the highest point and explode every time! This is the scene we see now! "

　　 The unscrupulous Li Tai from the past has now transformed into a physicist. He explained to Li Er the stress analysis of fireworks and shells. I heard that Li Er, Empress Changsun, Li Chengqian, Changle and others are the same. Stunned for a while!

　　"Thrust, gravity?"

　　 Faced with these new terms, Li Er was a little caught off guard. Although he glanced at the physics textbooks of the academy, he only glanced at it and did not delve into it. Of course, what caught him off guard was himself. His son only spent half a year at Yanhuang Academy. How could he know so many things that Datang didn't have before?

　　 Seeing his father, Li Tai’s sense of accomplishment bursts with surprise. It’s the same as some children show off in front of their parents and ask for praise after they know something amazing. Li Tai belongs to this now. Kind of super expressive person.

　　 "Ahem! Father, when it comes to gravity, it is actually..."

　　"That's all right! I roughly understand what it means!"

　　 Li Er waved his hand and interrupted his son's further "science popularization". At any rate, he is the supreme nation of a country. He was so "preached" by his own son. Doesn't he want face?

　　 Li Tae had to shut his mouth angrily.

The Changle on the side of 　　 suddenly thought: "Brother Xiaoxuan, since this gunpowder can push the projectile up to the sky, can it send people to the moon?"

　　 Li Er's eyes lit up suddenly, and he turned his gaze to Li Zexuan. The experience of observing space with an astronomical telescope at Yanhuang Academy that night is still unforgettable for him. At this moment, Chang Le's suggestion made him feel a little moved.

　　 Although Li Zexuan said that night, it takes at least a hundred years of technology accumulation to send humans into space, but what if there is a shortcut?

　　 "噗~!"

　　 Li Zexuan almost vomited blood when he heard the words. What Changle said was a bit similar to a rocket. I didn't see that although the little girl didn't have much contact with engineering, her idea was quite bold.

　　"Changle, although gunpowder is infinitely powerful and can push objects into the sky, once it is ignited, it will explode instantly. It can only provide instantaneous explosive power. We cannot control its burning speed, so it cannot provide continuous The thrust of the heavy object or human body is sent out of this land under our feet!

　　 In addition, with the current conditions of Datang, even if a person is sent out of the earth, there is no guarantee of his survival in outer space! After all, there is air on the earth, but not elsewhere! "

　　 Li Zexuan explained as far as possible in a language that Changle can understand.

　　 "Oh!"

　　 Changle thought for a while, then nodded seemingly.

　　 Li Er waved his hand and said: "Those who make big things do not stick to the trivial! If your kid has the ability to send people to the moon, just send them, as for whether that person can survive on the moon, you don't have to worry about it!"

　　 Old Li always has an obsession in his heart, that is God! Even if he didn't come in person, the people he ruled would do! This is something that the Three Emperors and Five Emperors, Qin Huang and Han Wu couldn't do!

　　 For this, make a small sacrifice, what's the point?

　　Li Zexuan rolled his eyes and didn't speak. He didn't bother to argue with Li Er over this matter!

　　 What a sacred thing the aerospace industry is, even if Datang is able to carry out manned spaceflight in the future, as long as he is there, he will not allow anyone to mess around!

　　 Li Er saw what Li Zexuan was thinking at first glance. He shook his head, thinking that today is New Year's Eve, he didn't say anything to blame, but said in his heart: This kid is still too kind!

　　.……………………

　　"Boom boom~!"

　　The sky of Yunshan Mountain is particularly charming tonight!

After the students in Class 1 of 　　 finished the fireworks, Li Zexuan let the remaining guards of the college "come into battle". Before, four fireworks were set off, and then a dozen fireworks were directed towards the sky!

　　 Colorful sparks fly up and down, blooming proudly in the air. The red, orange, yellow, green, blue, and purple, everything is complete, colorful, decorating the night sky beautifully and gracefully, and illuminating the earth like the day. This is really the fire tree and silver flower that never sleeps, fireworks are flying to welcome the new year!

　　The people on the Yunshan Mountain and at the foot of the Yunshan Mountain have never stopped their exclamation from the moment until now. Most people rarely blink their eyes, and they have completely lost the beauty of fireworks. !

　　 But tonight’s fireworks lasted unexpectedly long, a quarter of an hour, two quarters of an hour, three quarters of an hour, four quarters of an hour, the bells of the ugly time rang, but the fireworks on Yunshan never stopped. Meaning, while this made everyone screaming for fun, they lamented again and again, because the neck hurts from looking up!

　　 In the end, many people simply get some hay and lay them on the ground and lie down on their backs, while the rich children or the rich masters who have the conditions ask people to get pads or quilts on the roof of the carriage. Just lie on it, so that you can enjoy the fireworks in the sky, and save worry and effort!

　　 And Li Zexuan, after watching the fireworks for a quarter of an hour, he took his wife and Lao Li's family to the top floor of the tower on the left of Guanghua Building~IndoMTL.com~ Oh, it should be Li Er to be precise I took him here, because the tenth floor of the tower on the left is the office of Li Er, the dean of the academy. Only Li Er has the key, but Lao Li has never been here before. Today is the first time!

　　 entered this "dean's office", a few people lay down on the sofa, and through the large floor-to-ceiling windows, they could see the fireworks above the playground.

　　 ugly four quarters, all the fireworks were all set off, and Li Er stretched out. This New Year’s Eve, he was very satisfied, and it can even be said that it was the most satisfying New Year’s Eve in his life!

　　 Old Comrade Li is satisfied. Of course he has to show his favor to his courtiers. He stood up and said to Li Zexuan: "Tomorrow, oh, no, it is today, today the Great Court will meet. I will temporarily lift your ban on foot. You kid remember to attend on time, if you are late or absent, hum~!"

　　 After that, he took Chang Le, the eldest grandson, Li Chengqian and others and left, leaving Li Zexuan with a dull look!

　　 "Damn! God the thief! What the **** did you do wrong? Are you going to punish me like this?"

　　For a long time, Li Zexuan pointed at the sky and cursed his mother.

　　 is watching tonight, will he still want to sleep in tomorrow morning? Still participating in the Great Dynasty Meeting? Join a hammer~!

　　 Yes, Old Comrade Li thought this was a reward, but Comrade Xiao Li thought it was punishment!
