Otaku Engineer in Great Tang Dynasty Chapter 1132: Hot weapons and improved fireworks!

? "Shanchang, this firecracker is so powerful when it explodes, have you ever thought of using it against the enemy?"

In Yunshan Guest House, Li Zexuan had just sent Pang Feiji away on the front foot, and the squatter came on the back foot. 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 customer, and said: "Why does Mr. Zhang San have this idea?"

"The firecrackers were silently used on the schedule 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 greater, wouldn't it be a threat to some masters?" /

The bearded man was silent for a moment and said blankly.

Li Zexuan didn't expect that the bearded guy would think about this, isn't the one he said is equivalent to a thermal weapon?

"Yes! In fact, as far as I know, there is a weapon that is similar to firecrackers. It can shoot out under the impetus of a substance. The speed is no less than that of ordinary master masters. This weapon has very low requirements for users, 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 extent, guns and guns would definitely be made by then.

The stunner 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 before, which proved that Li Zexuan had some ability to know everything, so listen. After Li Zexuan described 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? Shanchang, is the black powder in firecrackers used in this heat weapon?"

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

Li Zexuan said lightly.

He understands that because of his martial arts skills, he will inevitably be a little arrogant, and now instilling a little knowledge of heat weapons into this bearded man might 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! Snake Spirit Mountain was wiped out a few months ago, did you use that so-called heat weapon?"

Since coming to Chang'an City for so long, the guillotiner has already inquired about Li Zexuan, so it is not surprising that he knew about the Snake Spirit Mountain.

Li Zexuan's mouth twitched, is this considered as shooting himself in the foot? I wanted to "open my eyes" to the guillotine beard, and made him a little in awe, but unexpectedly let the guillotiner be slapped upright, guessing the real reason for the destruction of the snake spirit mountain!

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

"Almost!"

Li Zexuan gave a gloomy answer.

The guy with a beard 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 destroyed, it is personally brave It would seem so weak in front of you!

"Hey! Doesn't that mean that my generation of martial arts practitioners, the cold and the summer, and the hard practice of martial arts, are all for nothing? In the end, they are not as good as a common man with a hot weapon?"

The guy with a sigh suddenly sighed, and his aura became much depressed.

Li Zexuan was stunned. Only then did he understand 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!

"Hehe! 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 and fiercely with others. If Mr. Zhang San can have the high level of strength now, presumably his martial arts perception will not be so superficial;

Secondly, martial arts can strengthen the body and even prolong life. People's life is short. What can be more important than living two years;

Thirdly, although thermal weapons are powerful, ordinary thermal weapons can hardly hurt martial arts masters 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, in the face of thermal weapon attacks, martial arts masters are obviously more likely to survive than ordinary lives;

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!

So, 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 stood up and clasped his fists and said: "It looks like a certain family! You are ashamed of a dozen-year-old person who is not as good as a mountain leader! You are ashamed! , A certain family won’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!

.………………………………

As it approached 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 goal, you have to add something to the fireworks!

Actually, 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, thereby producing different colors of light.

For example, when sodium nitrate is heated, electrons in sodium atoms absorb energy and are excited. When electrons transition from high energy level to low energy level~IndoMTL.com~ they will 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 are burned, 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.

If you know the reaction of the flames, 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 when fireworks explode in the sky, the person who makes the fireworks needs to arrange the positions of the metal elements in a certain order!
