Chapter 45 Window Paper

"If you see any good ideas in other places, you can also say them together, as long as it works, I will give you a gold ingot!" Zhu Bayi nodded slightly, and then continued to lure with gold. He remembered that before entering the workshop, Ivanov also asked a question about ironmaking. It's only the beginning, and it's all about the left and right. I can't be sure, this guy has seen a better way elsewhere, but he is reluctant to share it with others, and is holding it in his hands and waiting to make a lot of money in the future!

Sure enough, traveling thousands of miles is like reading thousands of books. The veteran ruffian wandered around all his life, and his knowledge was far greater than that of the craftsmen who stayed at home. Hearing Zhu Eighty-one say that there was more gold to take, he immediately cracked his big mouth full of yellow teeth, and said with a smirk: "Of course there is, of course there is." That, that iron, can't be made directly with peat. You, on the side of the capital of the Great Yuan Dynasty, have long used coke. It is to build a kiln like charcoal, and pile peat in it and burn it slowly. Then it will be stuffed for seven or eight days, and when it is watered, a large amount of coke will be extracted. Iron is made of this thing, and the fire is hard, and the iron that is smelted is strong. It's so much stronger than using charcoal! ”

"You old thing!" Zhu Bayi gently patted the back of Ivanov's head and counted it with a smile. "It's just a drop of money, holding a few big ingots of gold, and I'm not afraid of not being able to sleep?! Okay, Jinzi, you can go to Mr. Su at any time, that is, the place where you received the armor today. From today onwards, you will leave me here to teach everyone to make water hammers and burn coke! When will you get these two things out, and when will you come to me again! ”

After all, I thought that in this era, the information is not smooth, and there are many useful techniques that the craftsmen here in Xuzhou may not know, nor may they be able to master. Then he turned his gaze to Xu Hongsan and ordered loudly, "You go to Mr. Su in a while and ask him to give an order to the entire left army in my name." Whoever knows about the new methods of striking iron, making cannons, and making weapons can go to the Jiang's workshop and report to Master Huang. As long as he reports something, Master Huang can use it. I will reward him according to the size of the use. The greater the use, the higher the bounty, at least one copper coin, no cap! ”

"Yes!" Not only did Xu Hongsan answer very loudly. The eyes of the other blacksmith masters also lit up in an instant. The craftsman household, father to son, son to grandson, from generation to generation, who doesn't have a little bit of the trick of pressing the bottom of the box? In the past, everyone was like Huang Lao, afraid that the ancestral secrets would be stolen and learned, so they always had to keep a hand when they worked. Now that the Governor has promised a heavy reward, it is worth reconsidering whether to keep those unique skills in his family and pass them on to his son, or to exchange them for cash.

With similar thoughts, many craftsmen began to give Huang Lao crooked ideas for process improvement. There are also some who have no special skills in their stomachs, and they focus all their energy on the manufacture of bronze firecrackers, hoping that the rod they have made will win in the final choice and be favored and rewarded by the Governor.

Even so, when the first batch of bronze firecrackers was produced, half a month had passed. It took about a little time for the first primordial water hammer to be erected on the side of the creek, and it was only after the tightening of the upstream river was completed that it was ready for testing.

Zhu Eighty-one was overjoyed when he heard the news. Immediately, he ordered Mr. Su to come up with a sum of money and reward all the craftsmen involved in making the fire hammer and water hammer. Then he walked to a secluded place in the wilderness with the craftsmen holding the bronze firecracker, and began to fill the gunpowder one by one, realizing the power and strength of the new firecracker.

Because of the use of bronze with different formulas, the fire guns of different magnifications are fixed side by side on the pre-built earthen wall, and when the sun shines, it is immediately colorful. However, Zhu Eighty-one didn't have the heart to appreciate the beauty of this metal, and after everyone retreated to a safe distance, he immediately ordered a fire.

All I heard was "Boom! "Boom!" "Boom!" "Boom!" With a few sounds, the earthen wall where the firebolt was fixed was blown up into smoke and dust, and at the same time, the wooden target erected fifty paces away was also smashed by the projectile and the debris flew around, and it was no longer visible to the original.

"Hurry up and take a look, there are still a few shots that haven't exploded!" Before the smoke cleared, Zhu Eighty-one was the first to rush over and pick up the firecrackers next to the earthen wall one by one. I saw that two of the seven firearms had exploded, and two of them had cracked, and he had completely withdrawn from the competition. The other three doors, each looking heavier than the other, were all intact, except that one of them was so hot that a puff of green smoke immediately rose from the touch of his fingers.

At this time, no one cares about the pain in their hands, so they quickly wipe the wall of the fire gun with a damp cloth to cold, and then increase the amount of gunpowder and try again. In the second and third rounds of volleys, the three firearms still persevered, and it was difficult to distinguish between them. In the fourth round, when the amount of gunpowder was increased to three and a half weights, the hottest firearm was finally torn open from the inside, and it was no longer possible to participate in the follow-up practice.

The remaining two firecrackers were almost seven feet long. The caliber is almost three and a half times the original, from one and a half inches to four and a half inches, and the wall thickness is as high as four inches. According to the standard of another time and space, that is, about ten centimeters. It can no longer be counted as a firecracker, it is equivalent to a small bronze cannon.

However, the effective range of these two primitive bronze cannons is several times stronger than the one you saw a few months ago. It can shoot a large lead projectile specially made by Huang Laowei for these two firearms three hundred steps away, and can also smash a deep pit that is not big or small on the ground. If it is smashed on a person, even if he wears a large lotus leaf armor like a Rakshasa man, I am afraid that he will have a rotten stomach and die on the spot.

In addition to being overjoyed, Zhu Eighty-one ordered everyone to replace the projectiles prepared for several small firearms and test them again. The two bronze cannons could shoot 24,500 projectiles at a time, and the door panels of about 100 paces were full of pockmarked points. Fifty steps can break the leather armor, and if it is within twenty steps, the iron armor can also be bombarded into a sieve, and the gods can't stop it.

When the craftsmen saw the results, they all cheered loudly with excitement. Mr. Su, Yu Changlin and others, who had specially rushed over to join in the fun, were also surprised and delighted, and bent down to congratulate Lord Du Du on creating two more artifacts to defeat the enemy. Zhu Eighty-one was very happy in his heart, and ordered Mr. Su to take out the money and reward the makers of the two "fire guns" that persevered to the end, Huang Lao Crooked and Lian Lao Hei. Then he pointed to one of the ones that looked a little delicate and said, "This material doesn't need to be changed, and the caliber is reduced to less than two inches." The projectile is about the same size as the caliber, and the charge starts from five cents and is tried little by little, until the bore is blown up, and see what can be made in the end!"

When Lao Hei heard this, he quickly agreed, took the treasure fire gun and bounty he made, and ran back to work in the workshop.

Zhu Bayi looked at his back and shook his head, squatted down, drew a rough appearance of a later rifle on the ground with a tree branch, and pointed out to Huang Lao, the head of the workshop, "If his firecracker can be made according to my requirements, you can find wood and embed the firecrackle in the wood according to this look." As for your firecracker."

Looking at the thickness of the wall of the firebolt, he reluctantly accepted the reality, and while drawing on the ground, he ordered, "Just double it again, the caliber, the length of the tube, and the thickness of the wall are all enlarged in equal proportions." Then make a shelf and wheels, put it on it and push it away. If it succeeds, it will simply be called artillery! Remember not to make it too heavy, too heavy, you can only use it to defend the city! ”

"Alas, don't worry, this time, I will definitely be able to let you see a sample of the artillery within ten days!" Huang Lao patted his chest crookedly and said confidently.

"Take it slowly, don't hurt anyone, it's a little longer, and it doesn't matter!" The two souls have been fused for half a year, and Zhu Eighty-one can basically accept the slower pace of life in this era than the ox cart. Nodding his head, he smiled again.

"Yes! Governor, wait to hear the good news. Huang Lao crooked slapped his chest again, and carried his extra-large firecracker and bounty with his apprentices, and also happily went back to continue to do scientific and technological research.

"Although I have made two fours, after all, I have seen the light of day, which proves that my path is successful." While comforting himself in his heart, Zhu Eighty-one also followed everyone back. When I walked to the river and saw the water hammer that was trying to turn, the last trace of regret in my heart instantly flew away without a trace......

This thing isn't really anything new! The first half of the waterwheel has been used since the ancient Central Plains, especially south of the Yellow River. Some time ago, the Great Yuan Dynasty built water conservancy and built a lot of waterwheels to drain silt. Therefore, many old craftsmen in the workshop have seen the original with their own eyes. They took everything they had learned, put it together, and pieced it together a few sketches of the water hammer drawn by Ivanov, and they made it very easily.

This waterwheel, which combines the characteristics of the East and the West, is not only more beautiful than any of the originals, but also uses three bronze gears to bite and drive, and the efficiency is more than a little higher than any of the originals. (Note 1)

As for the mechanism for the forging hammer to pull up and fall, it is a layer of window paper. It's nothing more than a coordinated fit between the lever, the counterweight and the hammerhead. For the craftsmen who had just finished helping Li Sicang make the return cannon, there was no difficulty at all. Replace the heavy sand bucket with a bucket, replace the cannonball bucket with an extra-large hammer, and then pull the water from the river into the bucket repeatedly. Whenever the large bucket on one side of the lever is filled, the lever is pressed down and the hammer on the other side is pulled up. When the hammer is pulled to a certain height, it triggers the mechanism to instantly empty the water in the bucket. Under the effect of the leverage effect, the hammer head of more than 500 catties quickly smashed down, smashed on the red-hot iron, and the red stars splashed in all directions, and in three or two strokes, it was completely smashed into a board-shaped.

"Can this waterwheel work with gears to drive the drill bit?" Seeing that the craftsmen knew how to use gears, the gun-making fire in Zhu Bayi's heart was ignited again, and he pointed to the waterwheel that was about to start running, and asked the craftsmen in a low voice.

"Yes!" The craftsmen's eyes lit up and they replied, "Put a vertical wheel here, a horizontal wheel here, and then use a horizontal wheel to drive the leather strings." Having a waterwheel instead of a diamond bow and pulling the back end of the drill pipe back and forth is definitely faster than turning it by hand. It also outputs evenly. Dudu, you are really Maitreya Buddha, and you know everything. Such a simple trick that we haven't figured out in our lifetimes! ”

Note 1: The waterwheel of the Yuan Dynasty was driven by a wooden gear occlusion.
