(Many brothers questioned why they didn't make firearms, and the next two chapters explained, and there will be developments in the future, so there is no hurry.) ）

In the second year of Emperor Jingdi, with the arrival of the New Year's Festival, it was the prelude. The shareholders of the Royal Industrial Group not only received a large amount of dividends, but also received a novelty called "firecrackers".

In the mansion of Sun Kunxie, the prince of the pawn state, the people were busy preparing the Chinese New Year's Eve dinner, and all kinds of exquisite meals gradually filled several large round tables in the main hall. Because Li Guang, the Taishou of Tianshui County, was in charge of the army outside, the eldest son Li Danghu, who was only twelve years old in Chang'an's Li Mansion, took care of the house.

Gongsun He and Li Danghu have been promoted to the prince's concubines a few years ago, with a rank of 600 stones, which is considered a high position compared to their peers. Although they have not yet become a soldier, because the two have been in charge of the army for a long time, they have faintly gained some power. Gongsun Kunxie was born in the Huns, his surname was heroic, informal, and he didn't put on the elders shelf, and even let Gongsun He and Li Danghu sit at the same table with him, which made the two embarrassed.

The other Gongsun clansmen in the Gongsun Mansion did not have any objections to this. Although they are now in the Han nationality, they have retained a bit of the surname of the grassland people, and they are already respected by the strong. In the face of strength, seniority is not a problem at all, and several uncles of Gongsun Kunxie are still alive, but they still respect him.

Fortunately, Gongsun He's surname was lazy, and Li Danghu was even more nervous, three or two jars of old wine were in his stomach, and both of them were drunk and called Gongsun Kun evil brothers, and they were almost choked to death by several old men of the Gongsun family. However, Gongsun Kunxi didn't think it was wrong, but looked at his baby son proudly and laughed.

As a vassal state that manages the internal and external affairs of ethnic minorities, the news that the military minister Shan Yuqin led hundreds of thousands of Xiongnu to invade Yanmen, but finally returned in vain, naturally could not hide from him. Contacted that at that time, Gongsun He was away from home for a few months, and after he came back, he was promoted to the prince's concubine at the age of twelve. Born in a family of generals, what is more glorious than making great achievements. Although the matter is confidential and cannot be announced to the public, Gongsun Kunxi's actions today are to implicitly announce to the clansmen that Gongsun He is the next head of the Gongsun family.

As night fell, people lit a bonfire in the front yard, took out the prepared bamboo, and threw it into the fire, and the air in the bamboo cavity was heated and expanded, causing the bamboo cavity to burst, thus making a crackling sound.

The children ran out of the main hall, laughing around the fire, their little faces full of excitement. The drunken Gongsun He left the wine table with great interest, ordered the servants to fetch a few firecrackers, staggered to the bonfire in the courtyard, and threw it into the bonfire with his hand.

"Not good! Hurry back! Seeing this, Li Danghu, who followed him, changed his complexion greatly, yelled at everyone, and then pulled Gongsun He's collar back.

There was a loud crackling, campfires dancing, and sparks splashing everywhere. A large number of small red cannonballs were blown away, hitting the surrounding people, and a large number of them would explode immediately. There was a burst of chickens and dogs jumping in the front yard, the screams of women, the cries of children, and the shouts of men, mixed together, noisy, and made the eyes of the head of the family, Sun Kunxie, tremble, and his beard turned up in anger.

When the Royal Industrial Group sent someone to send this firecracker, it explained the usage in detail, and demonstrated it several times, and repeatedly stated that it should be used carefully. Now that the baby son is so nonsense, it really makes Gongsun Kun cry and laugh. However, when he saw that many of his clansmen's clothes had been scorched with blackened holes, and their exposed skin had also been burned, Gongsun Kunxie began to face up to the power of the firecracker, and there was a lot of playfulness in his eyes.

Among the heads of the top powerful families, there must be many bad guys, and there are absolutely no stupid ones. On this Chinese New Year's Eve, with the sound of earth-shattering firecrackers sounding one after another in the Northern Quejiadi, many Han magnates began to seriously examine the situation. They are soberly aware that the purpose of the Royal Industrial Group to give shareholders a large number of firecrackers is probably not the so-called happiness of His Majesty and the crown prince, but a declaration and warning. They had no doubt that the seemingly lethal firecrackers, if they collected a certain number, would be quite powerful.

According to common sense, when the emperor has this kind of thing in his hand, he will often hide it as a backup hand in case of emergency. However, His Majesty's grandiose announcement is now public, and the implication is quite intriguing.

Emperor Jing, who had a family banquet in Changle Palace and returned to the imperial study of Weiyang Palace, squinted his eyes slightly, looked at Liu Che on the side seat, and asked quietly: "Why did the emperor agree to give King Liang two more carts of firecrackers?" ”

Liu Che's face was full of innocence: "Uncle Huang seemed to be very interested, so he casually agreed." ”

Emperor Jing raised his eyebrows and said disdainfully: "Don't bluff me, according to your cunning surname, you naturally know what King Liang has in mind!" ”

"Uncle Huang still has any ideas, but he just wants to find out the details of the firecrackers, maybe he still wants to secretly make more in private." Liu Che pursed his lips and said jokingly: "I'm afraid there are a lot of powerful people who have the same idea as him, and I think someone has already split and checked it." The black powder in firecrackers is simple and mixed several times, and it is not difficult to know the formula. ”

Emperor Jing agreed with his jaw and said with a slight doubt: "Oh? Knowing this, why did the emperor announce such a sharp weapon to the public? ”

"Black powder is a weapon? It's just a money-making thing. A few days ago, didn't Erchen show his father various weapons made of black powder in the Yulin Camp? Father thinks it can be of great use? ”

Emperor Jing thought for a moment and shook his head: "The clay pots filled with black powder you made need to be ignited with fire in advance. ”

Liu Che shrugged his shoulders and said, "What my father said is extremely true, whether it is range or power, it is far from enough. If it is used in field battles, it will at most panic the enemy for a moment, and it will not be very effective. Besides, this black powder is very susceptible to moisture, and in the rainy season, once it is not properly managed, it can no longer be used. Moreover, the black powder ignites when it encounters fire, and if it is stored in large quantities, the hidden danger is very great, and I am afraid that it will hurt itself before hurting the enemy. ”

Emperor Jing frowned, and asked quite unwillingly: "However, if this black powder is collected in quantity, the power is still considerable, doesn't the emperor have other good ideas?" ”

"Erchen can make guns and artillery, relying on black powder to shoot projectiles a hundred steps away, but the power is too small, the range is too short, and it is not needed in field battles for the time being." Liu Che was silent for a long time and replied helplessly.

Liu Che deeply understood that even after the appearance of black powder for a thousand years, by the end of the Ming Dynasty, the firearms battalion equipped with firearms and artillery was still abused by the Manchurian Eight Banners cavalry in the field and could not find the north. This is also the fundamental reason why he disdains to be secretive, Liu Che does not believe that King Liang and the Han magnates can make a big killing weapon with black powder, otherwise it will be an insult to the wisdom of the entire Chinese nation for more than a thousand years.

What Liu Che doesn't understand is why other traversers with the halo of the protagonist don't announce it, and they have to guard the gunpowder workshop with heavy troops, which is pure nonsense! **, in the early Tang Dynasty, there was a saying that there was one nitrate, two sulfur and three charcoal, and the best ratio of 75:10:15 was completely known to the people in the late Tang Dynasty. In the history of China, which dynasty was overturned by black powder?! Secrecy is pure egg pain!

It was not until great advances in metallurgy that it became possible to use hand-held gunpowder weapons such as muskets. However, black powder has low energy and low power, and there is smoke and solid residue when burning, making firearms extremely powerful and efficient. It was not until the advent of explosives such as smokeless gunpowder, ** and nitrocellulose (nitroacid cotton) that the absolute advantage of hot weapons over cold weapons was truly formed.

Emperor Jing was silent for a long time, and asked quietly: "In a few days, we will march into the land of Henan, can it come in handy at that time?" ”

"Erchen can make a firearm called an explosive pack, but the inside is not wrapped in black powder, but the so-called high explosive, and it is no problem to use black powder as the ignition powder to collapse the city gate and city wall." Liu Che pondered for a moment and said seriously.

"So good! In this battle, it is inevitable to attack the city, if you can blast open the city gate and city wall, it will greatly reduce the damage of our Han soldiers! Emperor Jing's spirit was shocked, and he hurriedly sat up straight, obviously attaching great importance to it: "If it is really as the emperor said, it is really a great achievement!" ”

Liu Che said confidently: "Although the father and emperor can rest assured, everything is on the son." ”

Indeed, as a master's degree in chemical engineering, high-explosive ** is not difficult for Liu Che.

Nitrocellulose is nothing more than soaking cotton in a mixture of nitric and sulfuric acid to wash away excess acid. Glycerol can be separated by heating sulfuric acid and fat together, and half of glycerol can be prepared by dropping into a mixture of nitric acid and two concentrated sulfuric acid. Wood pulp is mixed with ** to make a high-explosive liquid Dana explosive. The ** is added to nitrocellulose to prepare colloidal dana explosives.

The "father of modern explosives" Nobel added ammonium nitrate to Dana explosives to replace part of the ** to make a safer and cheaper "special Dana explosive", also known as "extra strong yellow gunpowder".

It can be said that with the completion of a large number of sulfuric acid plants, all the raw materials of special Dana explosives are complete, and as long as Liu Che is willing, he can manufacture a large number of special Dana explosives at any time.
