"Mountain Chief, this firecracker is so powerful when it explodes, I wonder if you have ever thought of using it against the enemy?"

In the Yunshan Courtyard, Li Zexuan had just sent Pang Feiji away with his front foot, and the bearded guest came with his back foot, and 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 thoughts?" ”

"Yesterday, Cheng Chu used that firecracker to almost injure a certain family, and last night a certain family thought of a question, if the power of your firecrackers is greater, wouldn't it be able to threaten some masters of the rivers and lakes?"

The bearded guest was silent for a moment, and then said with a blank face.

Li Zexuan didn't expect the bearded guest to think in this direction, isn't what he said equivalent to a thermal weapon?

"That's right! In fact, as far as I know, there is a weapon similar to the principle of firecrackers, it can be shot out under the impetus of a substance, and the speed is no less than that of ordinary grandmasters, and the requirements for the user of this weapon are quite low, and ordinary people who have not practiced martial arts can easily control it! I call this a thermal weapon! ”

In fact, the thermal weapon he is talking about is the gun.

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

The bearded guest was even more shocked when he heard this, he didn't suspect that Li Zexuan was telling lies and alarmists, he had seen the detailed chart on the sea before, which had proved that Li Zexuan had some kind of ability to know everything, so after hearing Li Zexuan describe a thermal weapon, he was not suspicious at first, but shocked! If the thermal weapon Li Zexuan said really exists, then the matter will be even more serious than what he worried about last night!

"Thermal weapons? Yamaga, did you also use the black powder in firecrackers in this thermal weapon? ”

"That's right! But I call that powder gunpowder! Depending on the use, the formula of gunpowder will be different, and correspondingly, the power emitted by gunpowder will be different! The kind of gunpowder in the firecracker is the least powerful gunpowder! ”

Li Zexuan said lightly.

He understood that the bearded man would inevitably be a little arrogant because of his superb martial arts, and now instilling a little knowledge of hot weapons in this bearded man might make him feel a little awe!

"The least powerful one!"

The bearded guest's pupils shrank, and only then did he feel a little like a frog at the bottom of a well, "That's right! A few months ago, the Snake Spirit Mountain was destroyed overnight, did you use that so-called thermal weapon, Mountain Chief? ”

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

The corners of Li Zexuan's mouth twitched, is this considered lifting a stone to shoot himself in the foot? I wanted to "open my eyes" to the bearded guest and make him feel a little awe-inspired, but I didn't expect to let the bearded guest hit the right one crookedly and guessed the real reason for the fall of the snake spirit mountain in the first place!

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

"Almost!"

Li Zexuan depressedly gave an ambiguous answer.

The bearded man gasped, he was really frightened by the power of the kind of thermal weapon described by Li Zexuan, a powerful Jianghu sect, he would be destroyed when he said it, and his personal bravery would seem so weak in front of a hot weapon!

"Alas! Doesn't that mean that my generation of martial arts practitioners, cold and summer, hard practice of martial arts, all in vain? In the end, he is not as good as a mortal man with a hot weapon? ”

The bearded guest let out a long sigh abruptly, and the momentum on his body became much more depressed.

Li Zexuan was stunned for a moment, only then did he understand the real purpose of the bearded man who came here today, it turned out that this bearded man was almost injured by fireworks yesterday, which caused the heart of martial arts to be hit!

"Huh! Mr. Zhang San's statement is fallacious! ”

Li Zexuan pondered for a while in his heart, and said with a smile: "First of all, practicing martial arts is not to be brave and ruthless with others, Mr. Zhang San can have today's superb strength, presumably the martial arts perception will not be so superficial;

Secondly, practicing martial arts can strengthen the body, and even prolong life, people's lives are short, what can be more important than living two more years;

Third, although thermal weapons are powerful, it is difficult for ordinary thermal weapons to hurt a martial arts master of your realm! Besides, if both sides have thermal weapons, martial arts masters will definitely be much higher than ordinary people in using thermal weapons by virtue of their own abilities! Moreover, in the face of the attack of thermal weapons, martial arts masters are obviously more likely to survive than ordinary people;

Fourth, if the Tang Dynasty can really create hot weapons in the future, it will only be in the hands of the imperial court, and the people will definitely not have it, and law-abiding warriors don't need to worry about the threat of hot weapons at all!

So, in general, a person with martial arts, whether there are hot weapons in this world or not, he will have an advantage! Mr. Zhang San, your suspicions about martial arts are unnecessary! ”

The bearded guest realized, and after being silent for a long time, he got up and hugged his fists and said, "It seems that a certain family is in love!" People who are dozens of years old are not as good as the mountain chief, you can see it, you are ashamed! In this case, a certain family will not bother! Leave! ”

With that, he turned and went out the door.

Li Zexuan shook his head helplessly, the bearded guest came out like this today, in fact, it made him feel quite fresh, a peerless master, he could actually see the threat from the firecrackers, and there was no one else with this unique eyesight!

.………………………………

When it was close to noon, Pang Feiji came back with several bags of materials, Li Zexuan checked it, and went directly to the backyard to do experiments.

He's going to make real fireworks, the kind of fireworks that are colorful and come in all shapes!

To do that, you'll have to add something to the fireworks!

In fact, every modern fireworks is made up of a "pod," each of which can be called stars, which are about 1 to 1.5 inches (3 to 4 centimeters) in diameter. In a fireworks explosion, the atoms of each star absorb energy and then produce light when 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 atom absorb the energy and are excited. When electrons jump from a high energy level to a low energy level, they release about 200 kilojoules of energy per mole, or the energy of yellow light.

This is chemically called the flame reaction.

After the combustion of different metals, the light emitted is different, for example, the calcium element, its flame color reaction is red like bricks;

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

If you know the flame reaction, you can understand how colorful fireworks are made. In fact, it is to put different metal elements into fireworks according to different proportions. When the fireworks are lit, they will react differently in the sky, emitting different colors of light.

As for how to control the shape of the flame when the fireworks explode in the sky, it is up to the fireworks maker to arrange the positions of the metal elements in a certain order!
