Chapter 280: Liu Bowen (I)

"Thank you, thank you, Governor." Jiao Yu happily agreed while trying his best to break free from Zhu Chongjiu's claws.

Different from the random rewards of other princes, under the rule of the Huaiyang Governor's Office, there are standard bonus numbers to correspond, and the merits at all levels can also be recorded in the performance appraisal of the bureau, as a reference for future promotion, and the merit is a special merit, and the winner can directly withdraw the bonus of 1,002 and 24 yuan from the household bureau, or the equivalent of gold and silver satin.

At present, the best building lot in Yangzhou City has just been cleared out, that is, the location next to the general manager's line, each mu is only about 20 yuan, and half of the bonus is enough to buy a house foundation of more than 20 acres, and then spend seventy or eighty yuan, which is enough to build a courtyard with a garden, a complete masonry structure, and even the road is paved with cement.

"Don't forget to build a special gun mount for this kind of gun, otherwise it will be a big trouble to fix it in the event of a war." Zhu Chongjiu thought about it and reminded him in time.

From the birth of the four-pound gun to the present, it has been based on the experience summed up in the actual combat, at least six times of heavy improvement, in addition to the latest increase in steel core and rifling, among the other improvements, the most influential is to manufacture a special gun mount integrated with the gun carriage, which makes the four-pound gun in the field, no longer need to be fixed with sandbags and soil, but at any time put down the other end of the gun truck, smash the above fixed frame into the soil, you can directly turn the gun carriage into the base, and then according to the special adjustment bracket on the gun carriage, Adjusting the initial angle of the gun at any time greatly improves both flexibility and deployment (Note 1)

"Yes, villain, my subordinates know." Jiao Yu is still not very comfortable with his identity as the dean of engineering, and habitually calls himself a villain.

"We don't have anyone here." Zhu Chongjiu patted Jiao Yu's shoulder, smiled and encouraged, in the eyes of people in this era, craftsmen are cheap jobs, even if they earn more money, they can't compare with scholars, traditional concepts can not be reversed in a day or two, he can only take a more gentle way, little by little.

"Small, small, lowly duty, minister, minister knows." Jiao Yu's eyes suddenly turned red, and he leaned over respectfully and made a long bow, choking in response, "Don't worry, jade, jade will definitely let the lord see a small cannon that can shoot scattered bullets within ten days." ”

"I'm waiting for your good news." Zhu Chongjiu smiled and nodded vigorously.

The other party is a technology nerd in this time and space, and in this person, Zhu Chongjiu can even faintly see the shadow of Zhu Dapeng in another world, so as long as he can, he will support and take care of this person.

Jiao Yu could obviously feel the importance that Zhu Chongjiu attached to him, so he tried every possible way to repay this kindness, hesitated for a moment, and said with red eyes, "Lord, Yu still has a mention of yì, I don't know if I should talk about it." ”

"Say it, it's all your own people, what's so taboo, even if it's wrong, I promise that no one will trouble you." Zhu Chongjiu glanced at him in surprise, his eyes full of encouragement.

"This, this, subordinates, Yu wants to say, wait, after the new iron-making furnace is built, it is best to change the fire gun to use the machine qì to boring the pipe." Jiao Yu struggled for a moment and whispered with great difficulty.

"Boring pipe, the original double-layer sleeve welding method, didn't you also create zào, why did you change it back." Zhu Chongjiu was slightly stunned when he heard this, and asked with a frown.

"Then, at that time, there was no three-edged boring machine, and no one could guarantee that the pipe drilled out would deviate somewhere." When Jiao Yu heard this, not only his eyes were red, but his face was almost dripping blood, "So, so the double-layer sleeve welding method must be better than the drilling method, and because of the residual welding lines in the pipe diameter, the double-layer sleeve welded barrel is only flat and flat, which is far more accurate than the barrel drilled." ”

Zhu Chongjiu once listened to Jiao Yu's report, and can roughly understand the principle, the barrel rolled out of the iron sheet, no matter how smooth it is polished, there will be traces of welding on the inner wall, and a circle of spiral welding lines inadvertently plays the function of partial rifling, so the barrel made by the double-layer sleeve welding method, after becoming a musket, is basically more than 80 steps, and it can also ensure a certain accuracy, rather than a musket like a drill pipe, and the projectile does not know where it flies away from 50 steps (Note 2)

He was strange, obviously the double-layer sleeve welding method was very mature, why Jiao Yu wanted to retreat to the drilling method, was puzzled, and heard Jiao Yu carefully add, "But the final stage of the sleeve welding method to make the barrel, the final stage is all manual, not only time-consuming and labor-intensive, the thickness of the tube, as well as the size of the inner diameter, can not guarantee unity, and the use of the barrel method, whether it is the initial iron rod, or the final barrel, all can be with the help of machinery, as long as the size of the mold and the three-edged boring knife are consistent, the barrel produced is exactly the same, In addition, if the barrel is changed to steel, it is possible to use a stick with a spiral wire to put it inside and crush the rifling, or even to use a special small corner rifle to draw the rifling inside as if it were a gun. ”

"You mean, in the future, all muskets will be rifled." Zhu Chongjiu keenly captured Jiao Yu's idea, and couldn't help but ask loudly, "What about steel, can our steel be supplied?" ”

"You can build a few hundred of them first, and match them with the Governor's guards." What Jiao Yu wanted was not to change the armor of the musketeers of the whole army, but to ensure the safety of his own lord as much as possible, "Then after the new iron-making furnace is built, Yu will work with Master Huang and others to figure out how to get more steel. ”

"Okay, just do as you say, don't think about it by yourself, pull a few more masters, and let them do it with you." Zhu Chongjiu thought for a while, and nodded lightly again, "In the future, there will definitely be more than a few of you in the Engineering Academy, you have to learn to take apprentices and assign tasks to them, otherwise, you will exhaust yourself to death." ”

He admires Jiao Yu as a technology madman, so he does not hesitate to point out how to become a leader of a science and technology team, because of gratitude, Jiao Yu is also willing to work hard to improve himself, in order to better repay his weight, the two major technology nerds talk about it, from science and technology to team management, and then from performance goals to task modularization, unconsciously, I forgot where I was, until there were people standing around me, I suddenly woke up, smiled and shook my head.

"Governor." Huang Lao Er glanced at Jiao Yu enviously, and then reported loudly, "After the cannon test, the longest range and effective range, as well as the results of shooting at different distances and angles, are all recorded on paper, and those with flowering bullets are also recorded in the back." ”

"Okay." Zhu Chongjiu took the record book and checked it roughly, and then returned it to Huang Laoer, "Find someone to copy a few more copies, and hand them over to the Engineering Academy, the Industrial Bureau, and the Grand Governor's Office for archiving, and keep a few points in your own hands, which will be used to train gunners for other artillery regiments in the future." ”

"Yes." Huang Lao Er put away the record sheet like a baby and responded loudly.

"Is there a tendency to blow up the chamber, but the problem has already appeared, and it has been dealt with in time." Zhu Chongjiu thought for a while and continued to ask.

"Nope." Huang Lao Er shook his head and responded very proudly, "On average, each shot thirty times, there were no cracks on the barrel, and the temperature was not too high. ”

"Then find a cannon to continue the test firing, and when igniting, people try to hide as far away as possible to avoid injury, and see how many cannons can be fired in a row at most."

"Yes." Huang Lao Er saluted again, but did not leave immediately, but glanced at Jiao Yu again, and then said in a somewhat envious tone, "Just now, when you were teaching Master Jiao face-to-face, Governor Luo, Director Lu and Shi Xuezheng came to look for you together. ”

"What are they looking for me?" Zhu Chongjiu Xun looked around, but there was no shadow of Robben and the others, and asked loudly.

"Governor Luo said that the shooting range is an important place for the military state, and he has a few civilian officials, so he will not come in, please ask the guards to bring you a message, saying that he is waiting at the gate of the barracks."

"This Luo Qingyuan, he pays a lot of attention to it." When Zhu Chongjiu heard this, he couldn't help but complain in a low voice, deep in his heart, but he appreciated this person a little more, looked back at Jiao Yu, and then looked at Huang Laowei and Huang Laoer and others who were trying to shoot together, nodded, and ordered with a smile, "Then you go on, I'll go and see what they are looking for me." ”

"Congratulations to the Governor." All the people straightened up and saluted him.

Zhu Chongjiu returned the military salute with a smile, and surrounded by Xu Hongsan and other guards, he strode outside the shooting range, and before he could reach the gate of the barracks, he saw Luo Ben, the prefect of Yangzhou, Shi Nai'an, the new governor of Yangzhou Road, and Lu Kun, the director of the School Bureau of the General Administration, waiting there with anxious faces, pacing back and forth while waiting.

"What's the matter, is the sky falling, and the three of you can't solve it at the same time." Zhu Chongjiu hurriedly walked a few steps and asked everyone loudly.

"Governor." The three of them gave a salute and said in unison, "The governor finally pulled out, hurry back to the city, Liu Ji, Zhang Yi and Song Ke, the three, came together." ”

"Liu Bowen, he is actually willing to come." First laughed at others and couldn't hold their breath, Zhu Chongjiu himself was so happy that he almost didn't jump, "Where, hurry, take me to see him immediately." ”

"He, they" Robben, Shi Nai'an, and Lu Kun looked at each other, and stopped talking.

"What's the matter, they're gone again." Zhu Chongjiu's heart sank suddenly, and his face was full of disappointment.

"No, no, no." Robben hurriedly waved his hand and added loudly, "Zhang Yi and Song Ke both agreed to go out, but my uncle Liu Ji just wanted to open a academy in Yangzhou, he said that he was disheartened and didn't want to be an official anymore, and he just wanted to find a safe place in the future and pass on his master's knowledge." ”
