Standing in front of the camp gate, watching Deng Heizi and Gao Liang leave, Wang Zheng was still a little reluctant, and now he finally understood how Yu'er and Wang Liu felt when they said goodbye.

Although the opponent this time is not even as good as the water bandits, Wang Zheng is not worried about the safety of Heizi and Gao Liang, but in the foreign battle, casualties are still inevitable, how can you know who is the loser.

Wang Zheng inadvertently bent his arms tightly, Yu'er seemed to feel something, looked up, smiled sweetly at Wang Zheng, still quietly leaned on his shoulder, blinking at the team that was gradually moving away.

"Xietai, Xietai! The test was successful... The test was successful! ”

Fan Ruohai came running with a gray nose, holding a bird gun in his hand, excited like a child.

After hearing what he said, Wang Zheng looked sideways, and he was also surprised, and couldn't wait to ask:

"What, how far can you hit this time?"

"If you go back to Xietai, you can wear iron armor within 100 steps, and the power is still strong 150 steps away, fortunately not disgraced!"

"Good!"

Shouting hello, Wang Zheng took the first bird gun in Fan Ruohai's hand, like a treasure.

"This is the power that a bird gun should have, Fan Ruohai, you and the craftsman of the blacksmith shop have made a great contribution this time, and immediately put this bird gun into production, and the more you make, the better."

In fact, this bird gun finally tried to succeed, thanks to Song Yingxing, it was in March of the tenth year of Chongzhen, a generation of famous books "Heavenly Creations" was published.

“... Where the hammer bird is hammered, first take an iron as big as a chopstick as the cold bone, wrapped in red iron hammer. The first is three connections, the interface is red, and it is trying its best to collide. After the combination, the quadrangular steel cone is used as a big one, and it is rotated through it to make the aurora clean, and there is no blockage in the medicine. ...”

Song Yingxing's Tiangong Kaiwu is known as the encyclopedia of the 17th century by Westerners, and is the world's first comprehensive work on agriculture and handicraft production.

The book consists of 18 chapters in three volumes, covering agriculture and handicrafts, such as machinery, bricks, ceramics, sulfur, candles, paper, weapons, gunpowder, textiles, dyeing, salt making, coal mining, oil extraction, and other production techniques.

The sophistication of his thinking profoundly embodies the state of the productive forces of the budding capitalism of the Ming generation, which is breathtaking.

The production process of this bird gun alone has been used for hundreds of years, until it was completely abandoned during the rise of the Westernization Movement in the late Qing Dynasty, from the first arquebus to the Second World War for hundreds of years, which can be said to have a long history.

Wang Zheng once heard the craftsmen say that before the publication of the Sky Kaiwu, the bird guns made by the Wei Institute were generally riveted, but it was inconvenient to manufacture, and it was fixed with two copper hoops in Wanli year.

But in this way, it is inconvenient to clean, Song Yingxing's method has the best of both worlds, which greatly shortens the production time of the bird gun, and indirectly provides great help for Wang Zheng to create the bird gun.

After listening to Wang Zheng's words, Fan Ruohai hesitated, and Wang Zheng asked again and again, and he said another problem.

Although it is no longer a problem to make a serious bird's gun, the progress is stuck in the raw materials.

At that time, if the bird gun wanted to be practical, the gun pipe had to be made of fine iron, and only the gun pipe made of such fine iron could be strong and durable, and there would be no shoddy explosion of the guard when shooting, as was the case with the first bird gun of the Wendeng camp.

The problem is, according to the craftsman, this kind of refined iron needs to use a full ten catties of crude iron to smelt a pound, and now Wang Zheng is not short of silver, and after hearing this, he is also very puzzled, isn't it very easy to solve, just send someone to buy it.

But the craftsman also said that although the crude iron is not worth much now, there are not many in Jiaodong, and the origin of the crude iron is generally in Shaanxi, Henan and other places.

Wang Zheng also understood when he heard this, it is estimated that Zhang Xianzhong and other rogues are now making the chickens and dogs restless, and such a heavy thing as crude iron is inconvenient to transport, of course it can't be transported at this time.

In this way, if you want to make bird guns in batches, the ochre mine that has just been discovered on Yangma Island must be taken.

Seeing Wang Zheng and Fan Ruohai talking while walking, Yu'er knew that they were talking about important things, and she had been following her obediently and listening quietly.

Even if it is made of fine iron, it is quite cumbersome to make, usually the fine iron is first rolled into two iron pipes, one large and one small, with large and small, so that the two are tightly attached, and then drilled into a smooth and straight pipe with a steel drill.

The drilling process is very precise, the average craftsman can only drill about an inch per person per day, and it takes about a month to drill into one, even if the old craftsmen found by Fan Ruohai have years of craftsmanship, they are only slightly faster, and this kind of work is not careless.

Walking to the shooting range, Wang Zheng motioned for the others to retreat, wanting to try the first shot of the bird's gun in person, but he just leveled it, but he heard Shao Yong behind him say loudly:

"Adults, let's let the little ones try the guns, once the bore is blown up..."

When Fan Ruohai heard this, he was also a little worried, if he blew up the credit, it would immediately become a sin of losing his head, and he was about to say something, but he saw Wang Zheng waving his hand.

"It's okay, this official still believes in the craftsmanship of the craftsman in the hands of the shopkeeper Fan, and there is no need to persuade him again."

Under Shao Yong's signal, a salt ding hurriedly draped a general's iron armor on the straw man eighty steps away, everyone felt a little hanging, and Fan Ruohai even thought about God bless.

After all, the concept of the small power of the bird gun is still ingrained in their hearts, and the straw man is eighty paces away, even the firearms of the Liaodong border army cannot penetrate the iron armor of the tartar at this distance.

I saw Wang Zheng clenching and leveling the bird's gun, igniting the fire rope, aiming at the straw man eighty steps away, at this time his eyes narrowed, his heart was also very nervous, he took a deep breath, Wang Zheng pulled the trigger violently.

"Bang!"

The white smoke rose suddenly, and there was a loud bang, even the people watching from the periphery were clearly in their ears, Shao Yong waved away a salt ding, ran forward in person, and when he saw this scene, his eyes immediately widened.

Dong Youyin looked over there for a long time and didn't listen to him, so he stepped forward to check anxiously, almost dropped his jaw in shock, and stammered:

"My dear mother... This... This..."

I saw a hole in the black hole on this iron armor, but the solid lead bullet was missing, and Shao Yong immediately called Yanding to look around.

"Found it, my lord, buckshot is here!"

A descendant of the salt ding found this lead bullet twenty paces away from the iron armor, and everyone looked at the bird gun in Wang Zheng's hand, and they couldn't believe it.

It turned out that the bird gun, which could only fight birds, why did it become so powerful in Wang Zheng's hands?

Not only did he pierce the iron armor, but he also flew forward for about twenty steps before losing his strength and falling to the ground, how could this be possible!

Wang Zheng exhaled lightly, but he didn't feel excited, walked to the straw man eighty steps away, looked at the iron armor with a frown, and asked in a deep voice:

"Shao Yong, where did this iron armor come from?"

Shao Yong heard Wang Zheng's question, and hurriedly said: "If you go back to your lordship, this is from the armory, and the iron armor worn by the generals of the Wendeng camp in the past. ”

Nodding, Wang Zheng touched this iron armor, it turned out to be the armor issued by the imperial court, no wonder it was pierced so happily.

Wang Zheng had never seen the Tartars, and he didn't know what the iron armor on their bodies looked like, but judging from what he knew, it must not be like this so-called iron armor of the imperial court generals.

Thinking of this, Wang Zheng frowned, the power of this bird gun is just enough for now, if it is taken to Liaodong to fight against the Tartars, I don't know how to die.
