At this time, the sky was gradually darkening, and Li Xiang confidently erected the small rocket in the center of the courtyard under the gaze of everyone, and the long fuse was exposed. Pen "Fun" Pavilion www.biquge.info

Li Xiang stood up and looked at the sky, then took a deep breath and said: "This rocket is actually very simple, that is, it is loaded with gunpowder in a bamboo tube, and the volume of gunpowder will expand thousands of times when it burns, and then it will be sprayed out from the tail of the rocket to generate thrust to send the rocket into the sky." If the thrust of gunpowder is large enough and the volume is large enough, then it can fly for miles. ”

Li Kang nodded and said, "It sounds reasonable, it's just that this rocket, my father heard that it is easy to fall, is there such a thing?" ”

Li Xiang smiled: "Yes, the rocket is easy to lose balance in the air and fall halfway, so it needs a set of stable flight devices." Na, it is a few triangular wing surfaces at the tail, after the rocket is launched, these ****** surfaces can make the rocket rotate rapidly, so as to achieve the purpose of stable flight. Just like a spinning top, as long as it keeps spinning, it is stable. ”

In fact, this bamboo rocket is a bit similar to the Congreve rocket, but at the front end of this bamboo rocket, it is loaded with fireworks, and Li Xiang uses a super 3D printer to print out some parts, so that it can release fireworks in the air like a spreader.

Li Kang also understood at a glance that the tail of this rocket was the same as the feather arrows shot by the soldiers, and the feathers were added to the back of the arrows, and the effect was the same, that is, to stabilize the flight of the arrows in the air, which was also the key for the archers to be able to accurately shoot the target at a long distance.

The little girl Yuru looked at Li Xiang more and more differently, in her eyes, Brother Li is omnipotent, this rocket specially made for her made her heart a great satisfaction.

Since Xue'er was washed away from her memory, she has slowly adapted to the life in the Li family, and she is slowly not afraid of Li Xiang, and she is naturally full of expectations for the rockets made by her young master, and what girl doesn't like to watch the brilliant fireworks?

"Let's all stand away, this rocket is also a dangerous thing, in case of an explosion, it's not a joke!" Li Xiang looked at everyone, "Now that I'm lighting the fire, you guys just wait to enjoy this different fireworks show!" ”

Seeing Li Xiang's solemn expression, everyone hurriedly retreated a few feet away and watched Li Xiang light the fire carefully.

At this time, Li Xiang took a fire fold, lit it in the dim light, and carefully moved it to the fuse of the rocket, although he was quite confident, but in case of emergency, after Li Xiang lit the fuse, he also hurriedly retreated a few feet away, standing with everyone, waiting for the moment when the fuse burned out.

The fuse was burning, countless sparks were scattered, and Li Xiang's mood became tense and complicated, this time it was actually a rocket artillery test, and he didn't dare to guarantee whether it would succeed.

As the fuse burned out, under the gaze of several pairs of eyes, a bright flame came out of the tail of the bamboo rocket, except for Li Xiang, the others had not reacted, the bamboo rocket flew into the air with a whoosh, a beautiful trajectory crossed in the night sky, the bamboo rocket flew to a height of about 20 zhang, and then began to scatter fireworks into the air like a goddess scattering flowers.

Beautiful fireworks bloomed, everyone was crazy, this fireworks is too beautiful, and the bamboo rocket is indeed magical enough! In previous years, although you can see fireworks in Lin'an City every Lantern Festival, the fireworks released by this bamboo rocket are different, it draws a beautiful scenery in the night sky, it is lonely, but more beautiful.

Li Xiang looked up at the fireworks in the night sky, and couldn't help but sigh in his heart, the fireworks bloomed brightly, in this cold night sky, showing a special beauty. Beauty is always ephemeral, like fireworks, just in that moment, a flash in the pan, and then disappear without a trace.

A moving voice sounded in his ears, it turned out that Yuru looked at the fireworks excitedly, and couldn't help but chant a famous poem: "The east wind blooms thousands of trees at night, and the stars are like rain." BMW carved cars are full of incense, the sound of the phoenix flute moves, the jade pot turns brightly, and the fish and dragon dance all night. The moth snow willow is golden, and the smile is full of dark fragrance. The crowd looked for him thousands of times, and suddenly looked back, but the man was there, and the lights were dim. ”

After reading this poem, there seemed to be countless stars in Yuru's eyes, anyway, Li Xiang felt so, because Yuru's beautiful eyes were looking at him affectionately at this time.

Not only Yuru, but even Xue'er's eyes when she looked at Li Xiang became confused.

Li Xiang coughed lightly and said: "Sister Yuru, this time I am fortunate not to be dishonored, and I have finally completed the task, how about it, this firework is still beautiful, right?" ”

Yuru nodded again and again: "Brother Li, you are so powerful!" Such beautiful fireworks are really rare in the world, Yuru is thinking, I am afraid that tonight, the entire people of Lin'an City will be overwhelmed by this fireworks! ”

The entire city of Lin'an is toppled but not so much, because Lin'an City is a metropolis with a population of one million, and although this rocket flies high, there are still many places where you can't see it.

At this time, there are indeed many people who have seen this different fireworks!

The concubines and ladies of the palace also saw the beautiful fireworks in the sky, but this beautiful fireworks only made them sad, because the beautiful fireworks withered quickly, isn't this just like their lives? The beautiful years are short-lived, and once you enter the deep palace, you are tantamount to pinning everything on the emperor, but how many people can be favored?

At this time, Emperor Lizong was admiring the moon in the imperial garden with his most beloved concubine Yan Guifei, and suddenly saw a beautiful fireworks in the shape of a ribbon blooming in the sky, then Yan Guifei was attracted, and when she saw the fireworks passing, Yan Guifei cried and said: "Your Majesty, this fireworks are so beautiful, but unfortunately they passed away in an instant, and the concubines thought of themselves, entered the palace at the age of fourteen, fortunately the emperor had mercy, but the concubines had passed away, just like the fireworks in the night sky, for fear that the emperor would never pay attention to the concubines again!" ”

Seeing Concubine Yan crying, Emperor Lizong hurriedly held her fragrant shoulder and said, "Aifei, I will never dislike you!" If the concubine likes it, I will immediately send someone to find the person who set off the fireworks, and then put some fireworks for the concubine to enjoy slowly, okay? ”

"Your Majesty, the concubine is just a momentary emotion! This is a matter of labor and mobilization, the concubines dare not let the emperor do it, and some people say that the emperor is not! Yan Guifei said sullenly.

Emperor Lizong patted his head and said with a smile: "Ai Concubine, look at my memory!" Actually, I don't need to look for it, I know who made this firework! It must have been set off by Li Xiang, the prisoner of the country's prison, and I will summon him tomorrow and ask him to make some more fireworks for his concubine, okay? ”

Yan Guifei saw that the emperor loved her so much, and she was naturally very happy in her heart, so she took the initiative to lie in the arms of the old emperor, although the emperor was old, but what did it matter? Which concubine doesn't want to fly on the branches at one time, she was finally favored by the emperor, naturally she wants the emperor to spoil her forever!
