"Chief, this firecracker is so powerful when it explodes. Have you ever thought about using it against the enemy?"
In Yunshan Villa, Li Zexuan had just seen off Pang Feiji, and the bearded guest arrived. As soon as the bearded man sat down, he asked such an inexplicable question.
Li Zexuan's heart moved. He looked up at the bearded guest and said, "Why does Mr. Zhang San have such an idea?"
"Yesterday, the schedule office silently used the firecracker, which almost injured a certain family. Last night, a certain family thought of a question. If the power of your firecracker were more powerful, wouldn't it be able to threaten some martial arts masters?"
The bearded man was silent for a moment and said expressionlessly.
Li Zexuan didn't expect that the bearded man would think this way. Isn't what he said equivalent to a hot weapon?
"That's it! In fact, as far as I know, there is a weapon that has a principle similar to that of firecrackers. It can be fired out under the impetus of a substance, and its speed is no less than that of ordinary masters. Moreover, this weapon is very effective against firecrackers. The user requirements are quite low, and ordinary people who have never practiced martial arts can easily control it! I call this kind of weapon a thermal weapon!"
In fact, the thermal weapon he is talking about is a gun.
The Chinese were the first to invent gunpowder, but it was originally used to make firecrackers. Instead, foreigners were inspired by gunpowder and made guns. Li Zexuan felt that when he led Datang's industry to evolve to a certain level, guns and cannons would definitely be created.
The bearded guest was even more horrified when he heard this. He did not doubt that Li Zexuan was telling lies or alarmism. The detailed chart he had seen at sea had already proved that Li Zexuan had some ability to know everything. So after hearing Li Zexuan's description After acquiring a thermal weapon, his first moment was not suspicion, but shock! If the thermal weapons Li Zexuan mentioned really existed, then the matter would be more serious than what he worried about last night!
"Thermal weapons? Chief Shan, is the black powder in firecrackers also used in this thermal weapon?"
"That's right! But I call that kind of powder gunpowder! The formula of gunpowder will be different for different uses, and accordingly, the power of gunpowder will be different! The kind of gunpowder in firecrackers is the least powerful kind of gunpowder!"
Li Zexuan said lightly.
He understands that the bearded man will inevitably be a little arrogant because of his superb martial arts skills. Now, if he instills a little knowledge of hot weapons in this bearded man, maybe he will develop a sense of awe!
"The least powerful one!"
The bearded guest's pupils shrank, and then he felt that he was a bit like a frog in the well, "By the way! Snake Spirit Mountain was destroyed overnight a few months ago. Chief, did you use that so-called thermal weapon?"
Having been in Chang'an City for so long, the bearded guest had already inquired about everything about Li Zexuan, so it was not surprising that he knew about Snake Spirit Mountain.
Li Zexuan's mouth twitched. Was this shooting himself in the foot? I originally wanted to "open the eyes" of the bearded guest and make him a little awe-inspiring, but I didn't expect that the bearded guest accidentally guessed the real reason for the destruction of Snake Spirit Mountain in the first place!
The inside story of this is currently top secret! The only people who knew were him and Li Er!
"Roughly the same!"
Li Zexuan gave an ambiguous answer depressingly.
The bearded man took a breath. He was really frightened by the power of the thermal weapon that Li Zexuan described. A powerful Jianghu sect was destroyed at a word, and an individual's bravery was unexpectedly strong in the face of a thermal weapon. Seems so weak!
"Alas! Doesn't that mean that my generation of martial arts practitioners have practiced martial arts hard in the cold and in the summer, all in vain? In the end, we are not as good as an ordinary person holding a hot weapon?"
The bearded man suddenly let out a long sigh, and his aura became much lower.
Li Zexuan was startled, and then he understood the true purpose of the bearded guest's visit today. It turned out that the bearded man was almost injured by a firework yesterday, and his martial arts heart was hit!
"Haha! What Mr. Zhang San said is ridiculous!"
Li Zexuan thought about it for a while, then smiled and said: "First of all, practicing martial arts is not to fight bravely and harshly with others. Mr. Zhang San can have such extraordinary strength now, and his understanding of martial arts must not be so superficial;
Secondly, practicing martial arts can strengthen your body and even extend your life. Human life is short, and what can be more important than living two more years?
Thirdly, although thermal weapons are powerful, it is difficult for ordinary thermal weapons to hurt a martial arts master of your level! Besides, if both sides have thermal weapons, martial arts masters will definitely be much better at using thermal weapons than ordinary people by virtue of their own abilities! Moreover, when faced with attacks from thermal weapons, martial arts masters are obviously more likely to survive than ordinary people;
Fourthly, if the Tang Dynasty is able to create thermal weapons in the future, it will only be in the hands of the imperial court and never among the people. Law-abiding warriors do not need to worry about the threat of thermal weapons at all!
So, in general, a person with martial arts skills will have an advantage regardless of whether there are hot weapons in the world! Mr. Zhang San, your doubts about martial arts are unnecessary! "
If the bearded guest realized something, after a long silence, he stood up and clasped his fists and said: "It seems that a certain family has a good look! People who are dozens of years old are not as clear-minded as you, the mountain chief. You are ashamed! In this case, a certain family I won’t bother you anymore! Farewell!”
After that, he turned around and walked out the door.
Li Zexuan shook his head helplessly. The appearance of the bearded man today actually made him feel quite fresh. A peerless master could actually see threats from firecrackers. No one else had such unique vision!
.………………………………
Near noon, Pang Feiji came back with several packages of materials. Li Zexuan checked them out and went directly to the backyard to do experiments.
He wants to make real fireworks, the kind that are colorful and have different shapes!
To achieve this goal, you have to add something to the fireworks!
Virtually every modern firework consists of a "pod," each called a star. These stars are about 1 to 1.5 inches (3 to 4 centimeters) in diameter. In a fireworks explosion, each star's atoms absorb energy and then produce light as they lose excess energy. Different chemicals release different amounts of energy, resulting in different colors of light.
For example, when sodium nitrate is heated, the electrons in the sodium atoms absorb energy and become excited. When electrons transition from high energy levels to low energy levels, they release about 200 kilojoules per mole of energy, which is the energy of yellow light.
This is called a flame reaction in chemistry.
When different metals are burned, they emit different light. For example, the flame color reaction of calcium element is as red as a brick;
The flame color reaction of copper element is blue, and the flame color reaction of potassium element is purple. There are also many metallic elements, each with its own unique color.
If you know the flame color reaction, you can understand how colorful fireworks are made. In fact, it is to put different metal elements into fireworks in different proportions. When the fireworks are lit, they will produce different flame reactions in the sky and emit different colors of light.
As for how to control the shape of the flames when fireworks explode in the sky, the person making the fireworks needs to arrange the positions of the metal elements in a certain order!
