"And this, sir."

Wang Debang looked like a treasure, pointing to a drilling rig on the side, this machine has a pendant and a steel drill bit, which can fix the barrel, and then use the pendant to drive the steel head to drill the barrel, only when the barrel is overheated, it will be paused, and the drill bit also needs to be replaced, but no matter how many defects, this drilling rig can drill out of the barrel with great efficiency, which also saves a lot of manpower and time.

Drilling the barrel of the gun is really a laborious, laborious and time-consuming job without much meaning, other work can also exercise the ability of the novice, this kind of work will only consume the enthusiasm and confidence of the novice, no one wants to fight with a wrought iron pipe from morning to night.

"Congratulations, sir."

"Congratulations, sir, congratulations."

"Congratulations to Mr. Wang."

Congratulations rang out all around, and everyone had a heartfelt smile on their faces.

Zhang Han felt sincere joy and heartfelt support from the faces of these people, and he also knew that these people were happy for the reward, and at the same time, they were happy for the honor and achievements of this collective.

There are some things that you can't do without money, but not everything can be bought with silver.

Zhang Han said: "Wang Debang is rewarded with one hundred taels this time, he is the host of the technical group, although it is a collective force, he is the main person in charge, of course, he deserves to be rewarded." ”

"The technical team can choose to hold a patent, and give the corresponding remuneration for each machine in the future, or receive a one-time patent buyout reward, of course, the reward is also rich, and it will not be under Wang Debang's first technological breakthrough."

Speaking of the first technological breakthrough, Wang Debang's face was a little unnatural.

The flintlock pistol is now said to be usable, and it will definitely be usable, and the firing rate is not low, and the effective firing range is between 60 and 80 steps, and the success rate of shooting has also increased with the crosshairs, but there is still a long way to go before the standard set required by Zhang Han.

A slight change in the reed will lead to the technical deformation of the whole gun, and then have to start again, the Firearms Bureau has not made a breakthrough in the research and development of rollers and punches, the main reason is that Wang Debang put the main technical personnel in the flintlock pistol research and development group.

Zhang Han didn't ask too much about the previous situation, in fact, he was still too eager, and his current achievements were mainly due to Li Dongxue.

Wang Debang was rewarded again, Yang Hegao and Chen Yaozong on the side were not envious and jealous, their eyes were also full of pride, in contrast, Li Changnian was a little lonely.

This time, Li Dongxue stepped forward and said, "My lord, there is also a breakthrough in the weapon armor battle. ”

Zhang Han said: "As soon as I came, I had good news, and it seems that I will come often in the future." ”

Li Dongxue smiled and said: "It's a coincidence, I already planned to invite adults to come and see here, and I originally planned to wait for two more days, but the adults came, of course, please stop by to see them." ”

Zhang Han originally planned to talk to him about artillery, but today's original work plan has been postponed, so he said happily at this time: "Very good, I'll go to the Weapons Bureau." ”

The whole north of Lizhuang has been occupied by three bureaus, the original shrubs from and the grove were cut down, the ground was burned, and then the soil was rammed, and then the straight and solid road was repaired, and then the river was repaired, the water conservancy had the experience of the previous waterwheel, it was easy to drive, the position of the three bureaus was from north to south, the river was the east-west flow, one end was high and one was low, and there was a narrow place in the middle and the waterwheel was used to make the river water become a torrent, so as to drive a lot of hydraulic machines in the future...... Zhang Han did not make mistakes in this matter, although there are not many hydraulic machines now, but he has done a good job of preparing in advance.

Zhang Han had thought about the steam engine, it seemed that the principle was not too complicated, even he knew the rough, but if you think about it carefully, it is still too complicated, who told him that he didn't even finish junior high school? This thing is not something that can be figured out with a single stroke of the brain, and it took hundreds of years for Europe to come up with this thing from theory to practice, and then it has come a long way to get it really practical, and it is a bit too fake for him to directly get this big killer weapon here.

The Weapons and Armor Bureau is in the middle, the Firearms Bureau is in the southernmost, and the north is the Carriage Miscellaneous Bureau, everyone follows Zhang Han together, the two sides are not far apart, there are some storage areas in the middle, Zhang Han just stopped by to take a look at the finished products that have been made.

"The waist knife is good." Zhang Han passed by a warehouse of the Ordnance Bureau, pulled out the scabbard, looked at the blade of the imitation Qi knife, and felt very satisfied.

The blade is straight, the handle to the blade is thicker and thinner, the blade is somewhat like a willow leaf, and some are like a wider knife, in fact, Qi knife is an imitation of the knife, although Qi Jiguang has a sharp weapon and tactics to restrain the sword, the battle damage ratio is amazing, but Qi Jiguang did not ignore the advantages of the enemy's weapons, some of the waist knives of the Ming army are too thick, some of the sabers weigh seven catties, too heavy, the Qi knife weighs about three catties to four catties, narrow and sharp, with a shield, draped in heavy armor, it is indeed the best weapon for jumping soldiers.

"If you buy this knife, I'm afraid it will cost about six taels."

The iron used in the general Qi knife is more miscellaneous, and the level of forging is also high and low, and even the handle and scabbard also have quality problems, among which the Ministry of Industry is the worst in production, the waist knife of the Ministry of Industry is three two and one hand, the general military town self-made is more than the Ministry of Industry with materials and labor, generally about five taels, if the level of Qi knife here in Li Zhuang is taken out to sell, it really has to be six taels or even seven taels and one handle.

Zhang Han's heart moved when he heard this, and said, "How much does it cost?" ”

"Originally, the cost was between four or seven to five taels." Yang Hegao said: "Now with the new machine, the cost has dropped by 30%, and now it is about 325. ”

"Good, good."

The idea in Zhang Han's heart became clearer and clearer, new machines will continue to appear, which means that the cost of labor and materials will be greatly saved, the time will be greatly saved, and it means that high-quality weapons can be produced in large quantities, and the bottleneck of equipping troops no longer exists, and even more things can be done.

What's even better is that Lingqiu has solved the problem of supplying refined iron, even if Lingqiu produces refined iron, the quality is far less than that of Fujian iron, and mass manufacturing requires a large number of Fujian iron, and the cost will definitely not be reduced, and even if the cost can be reduced, Zhang Han has to have the ability to buy these Fujian iron.

"This is a wire drawing machine, which was successfully developed by the villain and Lao Chen."

The wire drawing machine in front of Zhang Han is driven by water power, and the artificial screw keeps driving the machine, and the thick iron is fixed from one end, and then the machine continues to stretch the wire, and finally what comes out is the suitable thin iron wire.

Chen Yaozong's black face was full of excitement, and he said: "With this machine, with the human hand in front of you, the chain mail can make five to ten collars a day, and there is no problem with two hundred collars a month." ”

This craftsman who can make chain mail is still a master dug by Zhang Han from Beijing, and there are dozens of apprentices with Chen Yaozong, but these hands are only made less than ten collar armor a month, mainly because it is too labor-intensive to knock on the iron ring and then inlay, the chain mail appeared in China at the turn of the Yuan and Ming dynasties, the process gradually matured, and there were also Ming chain mail in later generations, and the earlier ones were gone, China was mainly based on the armor and scale armor, and the trend of cotton armor and chain mail appeared in the Ming Dynasty, mainly because of the influence of cold and heat, soldiers and weapons, and the cotton armor province and iron and labor, anti-cold weapons are not good, but the killing effect of anti-bird guns is better, the chain mail is not anti-poking, and the defense against chopping and bows and arrows exceeds that of cotton armor.

Of course, these armors are not as high as the pure iron armor defense, but the pure iron armor is not only expensive, but also very labor-intensive and time-consuming to build, a collar of iron armor according to the previous quotation is close to the cost of twenty taels, now it must be more than fifty taels, and even in the war period, when the iron armor is seriously lacking, it is normal for a good iron armor to be sold for hundreds of taels.

The price of chain mail is not low, which causes the border army generals to accept chain mail very low, only the Beijing camp is equipped with a large number of chain mail, in the border army only elite family Ding will wear a layer of chain mail when wearing multiple layers of armor, a small number of Jurchen iron cavalry and white armor soldiers will also wear chain mail.

"Okay, everybody, you've been working hard."

Zhang Han really felt the efforts and achievements of his subordinates today, whether it was a roll machine, a wire drawing machine, or a drilling machine, these things made him feel the biggest changes he brought to this era.

Originally, of course, these things were also available in the Ming Dynasty, but all of them were purchased from the hands of the Jesu Society, whether it was a drilling machine or a boring machine and other machines, all of them were purchased, and then the Qing Dynasty, which immediately won the world, of course, did not need these complicated things, they felt that as long as there were bows and arrows, it was enough, so the door to technological progress was completely blocked, until people forced you to learn again.

In front of these machines, oiled, heavy machines themselves have nothing to call beautiful, but Zhang Han just felt a kind of beauty in the black fuselage and the strong smell of grease...... Unmistakably industrial beauty.

Although the machine in front of you and the screw that drives it are all handmade, they still exude the beauty of early industry.

Even these machines are not simple, at least in the Ming Dynasty, they do not have the ability to cast their own guns, they are all purchased from overseas.

"It's a hydraulic hammer."

Yang and others took Zhang Han to another workshop, where after being driven by a complex waterwheel, the heavy hydraulic hammer kept forging the iron ingots, which were constantly deformed and forged out of impurities, and then the craftsmen clamped the iron ingots with long iron tongs to make them look like they wanted.

"If you want a reward or a professional, you can choose for yourself."

After the inspection, Zhang Han sat in the fortification room of Yang He and others, drinking tea, and joked: "But you will become very rich no matter what." ”

Yang Hegao felt that the corners of his eyes were a little moist, his wife had given him the greatest support for a while, and he had hardly returned home, so he could go home to report the good news.

Chen Yaozong said directly: "The villains have already discussed, as long as the patent is required." ”

He smiled again: "Old Yang, isn't it?" ”

Yang Hegao nodded and said, "Yes, the water flows for a long time." ”

In the past two days, it has weakened and damaged my eyes, and the hospital casually prescribed 100 quick eye drops, which made me feel distressed.
