Vol 2 Chapter 1152: Reward? punishment!

　　 "This is the fireworks?"
On the edge of the playground, Li Erhang stood beside Li Zexuan. He looked up at the gorgeous fireworks in the sky. The surprise in his eyes was fleeting. Although he is the emperor of the world, this kind of dreamy and magnificent spectacle is also the first. See you again! He could not help muttering to himself.
　　 When Li Zexuan saw this, he couldn't help feeling a little proud. He could shock Li Er, a famous emperor, how many people in the world could do it?
However, while being proud, his eyes are still very vigilantly watching the students in the field who ran to light the fireworks. After all, this thing has blown up people, and the consequences are still very serious, so he must always pay attention. Ready and ready to save people!
　　 "Yonganhou, how can these fireworks soar to the sky?"
　　 Suddenly, Li Er asked such a "Xiao Bai" question. It seems that the sky has a very powerful attraction to the ancients!
　　 "Your Majesty, Qing Que should know this question, let him explain it to you!"
　　 Li Zexuan arched his hands and said.
　　 "Oh? Green bird, do you know the reason?"
　　 Li Tai, standing on Li Er's left hand, stood up excitedly when he heard the words, 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 projectile part of the top of the firework. Overcome your own gravity and fly to the sky quickly!
　　 And the upper end of the projectile, its fuze was ignited when it flew out of the pipe. The length of the 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 unruly Li Tai in the past has now turned into a physicist. He explained to Li Er the force analysis of fireworks and shells. Li Er, Empress Changsun, Li Chengqian, Changle and others were all taken aback. of!
　　 "Thrust, gravity?"
Faced with these new terms, Li Er was a little caught off guard. Although he glanced at the physics textbooks in the academy, he only took a few glances and did not delve into it. Of course, what caught him off guard was that his son was just After spending half a year in Yanhuang Academy, how could he know so many things that Datang didn't have before?
Seeing his father’s face full of surprise, Li Tai’s sense of accomplishment was instantly overwhelming. This is the same as some children show off in front of their parents and ask for praise after they know something amazing. Li Tai is now in this kind of desire for expression. Super strong person.
　　 "Ahem! Father, when it comes to gravity, it's actually..."
　　 "That's it! I have a rough idea of ​​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. Isn't he shameful?
　　 Li Tai had to shut his mouth angrily.
Chang Le beside 　　 suddenly thought: "Brother Xiaoxuan, since this gunpowder can push the projectile up into 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, Changle'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?
　　 "Puff~!"
　　 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 the girl hadn't had much contact with engineering, but her idea was quite bold.
"Changle, although gunpowder is infinitely powerful and can push objects to the sky, once it is ignited, it will explode instantly. It can only provide instant explosive power. We cannot control its burning speed, so it cannot provide continuous thrust. Send heavy objects or human bodies out of this land under our feet!
　　 In addition, with Datang’s current conditions, 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 did not come in person, the people he ruled would do! This is something that the Three Emperors, Five Emperors, Qin Emperor and Han Wu couldn't do!
　　 For this, make a small sacrifice, what can it be?
　　 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 has conditions for manned spaceflight in the future, as long as he is there, he will not allow anyone to mess around!
　　 Li Er knew what Li Zexuan was thinking at the first glance. He shook his head, thinking that today was New Year's Eve, he didn't say anything to blame, but said in his heart: This kid is still too kind!
　　.……………………
　　 "Boom boom boom~!"
　　 The sky of Yunshan Mountain is particularly charming tonight!
After the students in the first class finished the fireworks, Li Zexuan asked the remaining guards of the college to "come into battle together". Before, four fireworks were set off, and then more than a dozen fireworks pointed towards the sky!
　　 Colorful sparks fly up and down, blooming proudly in the air. Red, orange, yellow, green, blue, and purple, everything is perfect, colorful, decorating the night sky beautifully and gracefully, and illuminating the earth like daylight. This is really a fire tree 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 exclaiming from the first four moments to the present. Most people rarely blink their eyes, and they have completely lost the beauty of fireworks!
But tonight’s fireworks lasted unexpectedly long, one quarter of an hour, two quarters of an hour, three quarters of an hour, four quarters of an hour, and the bells of ugly time rang, but the fireworks on Yunshan didn’t mean to stop at all. While making everyone screaming, they lamented again and again, because the neck hurts from back up!
In the end, many people simply get some hay and lay it on the ground and lie down on their backs, while the rich children or the rich elders who have the conditions ask people to get pads or quilts and spread them on the roof of the carriage, and people just lie down. Go up, in this way, you can not only enjoy the fireworks in the sky, but also save worry and effort!
And Li Zexuan, after watching the fireworks for a quarter of an hour, took his wife and Lao Li's family to the top floor of the tower on the left of Guanghua Building~EbookFREE.me~ Oh, it should be Li Erdai to be exact He went there 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, through the large floor-to-ceiling windows, they could see the fireworks over the playground when lying down, it was extremely pleasant!
When 　　 was ugly, all the fireworks were finished, and Li Er stretched his waist. 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 was satisfied. Of course, he had to show his favor to the courtier. He stood up and said to Li Zexuan: "Tomorrow, oh, no, it is today, today’s Great Court meeting, I temporarily lift your ban, you kid remember Participate on time, if you are late or absent, hum~!"
　　 After all, he took Changle, Changsun, Li Chengqian and others and left, leaving Li Zexuan with a dull look!
　　 "Damn! God 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.
　　 Watch the year tonight, will he still want to sleep in tomorrow morning? Still participating in the Great Dynasty Meeting? Participate in a hammer~!
　　 Yes, Old Comrade Li thought this was a reward, but Comrade Xiao Li thought it was punishment!
