"Did he say that?" Bai Yijie put down the cast-iron barrel in his hand and asked back.

Zheng Yunming nodded thoughtfully, and Yang Luo, Wang Deng, Zhu Sheng, Qin Wu and others behind him all covered their mouths and snickered.

Bai Yijie turned back and continued to look at the iron pipe in his hand, and sighed: "Master said, only women and villains are difficult to raise, this is true. ”

On the day Zheng Yunming hurried back to Xiangyang from Changsha, he could still catch up with the bidding meeting in the Shuangjing test site in the west of Xiangyang City.

The so-called bidding for the purchase of firearms was a new idea that Zheng Yunming came up with with the assistance of the shogunate. The craftsmen and folk craftsmen under the jurisdiction of the government put forward their own new types of firearms, and then performed them at the test site for the generals in Xiangyang, and the government decided whether to carry out large-scale procurement, and if the government decided to procure, the government would pay a certain amount of remuneration to the Ming people according to a certain proportion of each firearm produced, and this fee was called exclusive interest, referred to as patent fees.

As soon as the announcement of the bidding method was announced, it immediately aroused a huge repercussion in Jinghu, and some enthusiastic craftsmen immediately calculated that according to the proportion of patent fees announced by the government, the craftsmen would make a much higher profit from a new weapon than the rewards and rewards offered in previous years.

Taking the Bamboo Generals who shined in the First Jinghu Defense Battle as an example, Jinghu produced 1,600 Bamboo Generals throughout the war, most of which were equipped with the Tulong Army. According to the government's announcement, each bamboo general can collect a patent fee of 21 yuan, and according to the calculation of 77 yuan in circulation, 1,600 bamboo generals will be able to bring 2,000 yuan to the Ming person. And then General Bamboo will be manufactured in large quantities in Jinghu, and according to the law that the enemy will inevitably attack in the autumn and winter every year, the number of General Bamboo will be made in the future will not be in the thousands? Then just such a small thing as Ming is enough to make people rich.

Therefore, when the ambassador of Jinghu Manufacturing and Manufacturing, Si Zhiri, openly began to bid for firearms at the Shuangjing Proving Ground, not only the craftsmen of Xiangyang and Jiangling, but also as far away as Jingnan, Jiangxi, and even Sichuan upstream, there were craftsmen who came to win the blue eyes of the envoys and generals with all kinds of their own whimsical ideas.

The small Shuangjing test site is like a lively bazaar, and the craftsmen set up their stalls and loudly beckoned the generals to see their new weapons.

The iron pipe in Bai Yijie's hand is the Ming of Ezhou blacksmith Qian Yiwu, he named the small firearm he built according to the number of ways Zheng Yunming named the firearm, but after Zheng Yunming checked it, he thought that in the future, it would be necessary to distinguish between the large-caliber firearms that were performed by multiple people and placed on the pedestal and the small-caliber firearms cast by a single person.

The word 铳 originally referred to the small hole on the tomahawk used to fix the iron pin, and Zheng Yunming mentioned that it was used as a unified name for small barreled firearms, and since then the prestige of the gun has become one of the symbols of the Jing Chu army.

Qian Yiwu's iron gun, the total length of the gun is one foot two inches, the depth of the chamber is more than six inches, the muzzle is eight points, the whole gun is divided into three parts: the chamber, the medicine chamber and the tail hammer, the medicine chamber is partially raised for filling gunpowder, and there is a fire door on it, which can fill the fuse. A wooden handle can be installed at the tail of the firebolt, and when shooting, use your arm to clamp the wooden handle and release it with fire. The whole firearm weighs seven and a half pounds, and a soldier is enough to shoot alone, but it only uses lead weighing seven coins as a projectile, and the range is only a few dozen steps, and the lead shot is also very insufficient.

Zheng Yunming was very dissatisfied with this, although this iron gun already had the appearance of some metal firearms, and it could be seen that the Ming had some ideas of his own, but the iron gun as a whole still copied the shape of General Zhu as it was, and it was just reduced for individual use. And when I saw the appearance of this iron gun, the thickness of the pipe wall was uneven, and if it was really taken to the battlefield to kill the enemy, I was afraid that before the gun could hurt the enemy, I would be blown up and take my life first.

He motioned for Bai Yijie to put down the firearm and look at it one by one along the stall.

The house next door was a gunsmith who made bamboo and wooden guns, and when he saw the deputy commander coming over, he hurriedly bowed and handed over a bamboo gun.

Zheng Yunming was quite puzzled at the beginning, today he is making the Yamen bid for firearms, why did this person come up and present a bamboo gun that has nothing to do with firearms?

He carefully examined the gun before revealing the joints, the iron head of the bamboo gun was not directly behind the barrel, but a bamboo barrel of more than two feet, the bamboo barrel was crossed with four thick hemp ropes, the mouth was smooth, and the barrel was inserted in the back. The gunsmith demonstrated to Zheng Yunming how to release the bamboo musket, because there was no fire door, so the fuse must be put in first, and then put in three or four coins of gunpowder to compress it, and then fill the bamboo barrel with a projectile. When shooting, the soldier bends his knees to hold the spear, ignites the fuse, grasps the handle of the gun with both hands without shaking, and ejects the enemy, and if the enemy rushes close, he will install the gun head and use it as an ordinary bamboo gun.

The gunsmith proudly named this weapon, which can be used as both a firearm and a cold weapon, as a fast gun. Zheng Yunming also felt that this idea was quite in line with the current army building idea of mixing hot and cold weapons, and it seemed that there would be no flaws when using it. This hybrid spear should be a handy weapon for city garrisons.

He immediately ordered to use this as a blueprint and tried to make 500 of them to be used as weapons to defend the city.

Seeing that someone was successfully selected, the craftsmen who set up the stalls were excited, and many people were about to rush forward to show Zheng Yunming with their works.

Under the reprimand and obstruction of the back soldiers, it was not easy to start the patrol again.

Zheng Yunming saw a craftsman who was stopped by the soldiers holding a stone in his arms, and his curiosity became great, and he asked, "Is this also a firearm?" ”

The craftsman laughed embarrassedly: "The little one is a stonemason, I heard my cousin who works in the gunpowder workshop mention that now after the innovation of the capital, the production efficiency of gunpowder has increased a lot, and the supply of gunpowder in each army is very sufficient, but the iron shells used to make iron cannons are not enough every month, so the production of iron cannons is limited." Isn't a small inspiration just a shell? Isn't it the same as iron artillery to dig a nest in the stone and fill it with gunpowder and a fuse fire? And there are stones everywhere, so you don't have to worry about the lack of materials. ”

"It's a good idea," Zheng Yunming praised, "In this way, the iron artillery used to defend the city no longer has to worry about the number of them." However, the materials for stone artillery are too cheap, and you won't get much money if you charge royalties proportionally."

The stonemason smiled innocently, "I just thought about it casually, and I didn't expect it to sell for much price." ”

"In this way," Zheng Yunming said, "I used 200 guan to buy your idea and the method of making zuò, which is like adding a lot of trouble to calculating the patent fee, what do you think?" ”

The stonemason didn't expect that he could get such a rich reward for such a simple idea, and immediately thanked and accepted the reward.

Immediately after, someone offered Zheng Yunming a mud pill.

Zheng Yunming almost burst out laughing, his original plan was to hope that someone could develop a firearm with a metal body, and he only needed to procure it. I don't want someone to offer bamboo spears first, and then stones, and now even mud balls are being presented.

He flipped over and examined the large mud pellet, which had a fuse attached to it, apparently filled with gunpowder.

"There is not only gunpowder in it, but also a poison that causes smoke, which is usually stored in wooden barrels, and when the city is defended, it is lit and thrown down, which can be burned and poisoned the enemy."

After the founding of the Great Song Dynasty, there were many such arson and smoke weapons, such as the thunderbolt cannon of Jingkang's year, and the sudden fire torch in the early years of Duanping, which was named by the Ming man as the big mud ball of the 10,000 enemies, at most it was just an enhanced version of these weapons.

He was only willing to offer a hundred guan to buy out, but Zhao Kui was very interested in the improved version of this traditional weapon, and he added an additional fifty guan to Zheng Yunming's reward.

The atmosphere of the bidding meeting became more and more enthusiastic, and when Zheng Yunming was overwhelmed, there was a middle-aged man sitting in the corner, who neither crowded around him like everyone else, nor shouted loudly to sell his Ming. Just sit quietly, as if an unrelated person came in to see the excitement and didn't want to participate.

Zheng Yunming looked interesting, and told Ma Guangzu and Wang Deng to deal with the swarming treasure donors, and quietly came to this person's stall.

When the middle-aged craftsman saw the deputy capital of Jing and E suddenly coming, he panicked, and he was at a loss to pick up his Ming to show Zheng Yunming, not wanting to be overly nervous, so he dropped the fire gun in his hand to the ground with a miss.

Zheng Yunming heard the sound of the fire gun falling to the ground, which was very different from the shoddy goods in front of him, and he became interested. He leaned over and picked up the firecracker, and weighed it in his hand, which probably weighed more than ten catties. The main part is generally similar to the first shoddy firecracker, but on closer inspection, the small part is different.

The breech part of this gun is no longer straight, but is thickened from the mouth to the chamber.

Clever way, Zheng Yunming thought, whenever the gunpowder hits, the chamber pressure that suddenly appears in the medicine chamber is the largest, and the more the projectile is pushed towards the gun, the lower the pressure. This is a simple truth, but these craftsmen only learned a few months ago that there are firearms in charge of projectiles, and those who can understand this truth must be people who are extremely meticulous in their observations.

He raised his head and smiled, "You came up with this fire hammer with a thin front and a thick back?" ”

Seeing that Zheng Yunming was speaking as kindly as the legend, the craftsman calmed down a little, blushed and said, "This is very simple."

Zheng Yunming looked at the way he struggled to speak, smiled and patted him on the shoulder, signaling him not to say any more. Keep playing with the new toy in your hand.
