Otaku Engineer in Great Tang Dynasty

"Shanchang, this firecracker is so powerful when it explodes, I wonder if you have thought about using it against the enemy?"

As soon as Li Zexuan sent away Pang Feiji in the Yunshan Courtyard, the squatter came on the back. As soon as the bearded man sat down, he asked such an inexplicable question.

Li Zexuan's heart moved, he raised his head to look at the bearded guy, and said, "Why does Mr. Zhang San have this idea?"

"The firecrackers were used in silence yesterday to almost hurt a certain family. A certain family thought of a problem last night. If the power of the firecrackers, Shanchang, you were more powerful, wouldn't it be a threat to some masters?"

The bearded guest was silent for a moment, and said blankly.

Li Zexuan didn't expect that the bearded guy would still think about this. Isn't the one he said equivalent to a thermal weapon?

"That's it! In fact, as far as I know, there is a weapon similar to firecrackers. It can shoot out under the impetus of a substance. The speed is no less than that of ordinary master masters. The user's requirements are quite low, and ordinary people who have not practiced martial arts can easily control it! I call this weapon a thermal weapon!"

In fact, the hot weapon he said is a gun.

The Chinese were the first to invent gunpowder, but at first it was used to make firecrackers. On the contrary, foreigners were inspired by gunpowder and made guns. Li Zexuan felt that when he led Datang Industry to evolve to a certain level, guns would definitely be made by then.

The bearded man was even more shocked when he heard this. He did not suspect that Li Zexuan was telling lies or alarmism. He had seen that detailed chart at sea earlier, which proved that Li Zexuan had some ability to know everything, so he heard Li Zexuan describe it. After using a thermal weapon, he was not suspicious for the first time, but shocked! If the thermal weapon Li Zexuan said really existed, then the matter would be more serious than he worried last night!

"Heat weapon? Shan Chang, is the black powder in firecrackers also used in this hot weapon?"

"Yes! But I call that powder gunpowder! The formula of the gunpowder will be different for different purposes. Correspondingly, the power of the gunpowder will be different! The gunpowder in the firecracker is the least powerful kind of gunpowder!"

Li Zexuan said lightly.

He understands that because of the martial arts skills, the beard will inevitably be a little arrogant, and now instilling a little knowledge of hot weapons into this bearded man, maybe it will make him feel a sense of awe!

"The least powerful one!"

The bearded man's pupils shrank, and then he felt a little like a frog at the bottom of a well, "By the way! The Snake Spirit Mountain was wiped out a few months ago, did you use that so-called thermal weapon?"

After coming to Chang'an City for so long, the bearded guy had already inquired about everything about Li Zexuan, so it was not surprising that he knew about the Snake Spirit Mountain.

The corner of Li Zexuan's mouth twitched, is this considered as shooting himself in the foot? I wanted to "open my eyes" to the Qiu Yanke, which made him a little in awe, but unexpectedly let the Qiu Yanke be slapped on the right side, and guessed the real reason for the destruction of Snake Lingshan!

This inside story is currently top secret! The only people who know are him and Li Er!

"Roughly the same!"

Li Zexuan gave an ambiguous answer depressed.

The guilty man took a sigh of relief. He was really frightened by the power of the thermal weapon described by Li Zexuan. A powerful martial art sect, even if it is said to be wiped out, personally brave in front of the thermal weapon. Looks so weak!

"Hey! Doesn't that mean that my generation of martial arts practitioners, who have been practicing martial arts in the cold and summer, are all in vain? In the end, they are not as good as an ordinary man with a hot weapon?"

The bearded man suddenly sighed, and his aura became much depressed.

Li Zexuan was stunned, and then he understood the real purpose of the stunner who came here today. It turns out that this bearded man was almost injured by fireworks yesterday, which caused a blow to the martial arts heart!

"Haha! Mr. Zhang San's words are absurd!"

Li Zexuan pondered for a while, and smiled: "First of all, martial arts practice is not to fight bravely with others. If Mr. Zhang San can have the outstanding strength now, presumably his martial arts perception will not be so superficial;

Secondly, practicing martial arts can strengthen your body and even prolong your life. People’s lives are short. What is more important than living two more years?

Third, although thermal weapons are powerful, ordinary thermal weapons can hardly hurt a martial artist in your realm! Besides, if both sides have thermal weapons, martial arts masters rely on their own abilities to use thermal weapons at a much higher level than ordinary people! Moreover, when faced with an attack from a thermal weapon, a martial artist is obviously more likely to survive than ordinary life;

Fourth, if Datang can really create thermal weapons in the future, it will only be in the hands of the court, and the civilians will never have them, and law-abiding warriors do not need to worry about the threat of thermal weapons!

Therefore, in general, a person with martial arts, regardless of whether there is a hot weapon in the world, he will have an advantage! Mr. Zhang San, your doubts about martial arts are unnecessary! "

If the bearded guy has realized something, after a long silence, he got up and clasped his fists and said, "It seems that someone is looking like a certain family! You are ashamed of a dozen-year-old person who is not as good as the mountain leader! Don't bother! Goodbye!"

After that, he turned around and went out.

Li Zexuan shook his head helplessly. The appearance of the guillotiner today actually made him feel quite fresh. A peerless master can actually see the threat from the firecrackers. This unique vision is no one!

Near noon, Pang Feiji came back with several packages of materials. Li Zexuan checked it and went directly to the backyard for experiments.

He wants to make real fireworks, the kind of colorful fireworks with different shapes!

To achieve this purpose, you have to add something to the fireworks!

In fact, every modern firework consists of a "pod", each pod can be called a star, the diameter of these stars is about 1 to 1.5 inches (3 to 4 cm). In a firework explosion, the atoms of each star absorb energy, and then produce light when it loses excess energy. Different chemical substances release different energy, thus producing different colors of light.

For example, when sodium nitrate is heated, electrons in sodium atoms absorb energy and are excited. When the electron high energy level transitions to the low energy level, UU reading www. uukanshu.com they release about 200 kilojoules per mole of energy, which is the energy of yellow light.

This is chemically called the flame reaction.

After different metals burn, the light emitted is different, for example, calcium element, its flame color reaction is red like a brick;

The flame reaction of copper is blue, and the flame reaction of potassium is purple. There are also many metal elements that have their own unique colors.

Knowing the flame reaction, you can understand how colorful fireworks are made. In fact, different metal elements are installed in the fireworks in different proportions. After the fireworks are lit, they will produce different flame color reactions in the sky and emit different colors of light.

As for how to control the flame shape of fireworks exploding in the sky, the person who makes the fireworks needs to arrange the positions of the metal elements in a certain order!
