Leaving the training ground, I went to the ward to visit the injured Xiao Liu. The wound on the stomach of the little fat man Liu Mingqiang has begun to scar, which is a good sign.

"You're so lucky, such a strict wound, and under such rudimentary care conditions, there were no concurrent infections."

Jack, a foreigner doctor, was originally very pleased with Xiao Liu's "good luck", but Lao Shi, another local doctor who traveled through the crowd, disagreed:

"What kind of luck, the bacteria of this era are not resistant to antibiotics at all, and it is strange that we have given him so many antibiotics that he can be infected."

Lao Shi's full name is Shi Yisheng - he was born to be called a doctor. Fujian Medical University, majoring in clinical medicine, has been engaged in surgical work for three years after graduation, focusing on trauma surgery, but this guy has been hiding among the "ordinary labor" crowd, and refuses to take the initiative to explain his specialty, saying that he doesn't want to see bloody scenes again.

Of course, in the end, it was found out, and doctors are always welcome, especially surgeons. Although there was no major damage to the crossing group itself, there were many seriously injured among their captives, and Jack alone would definitely not be able to keep it busy, so Dr. Shi had to pinch his nose and wander among the blood stains again.

Of course, the captives were not entitled to modern medicine, but the doctors trained by the medical schools in China must have studied Chinese medicine, and they knew a little about such classic works as the Compendium of Materia Medica. Using the herbs found in the crude medicine shop in the city, coupled with scientific bandaging, disinfection and nursing methods, Lao Shi dragged back a few lives from Lord Yama, and was very grateful among the captives.

But in private, Lao Shi told everyone that he was practicing with those captives.

Xiao Liu's spirit here is much better, and when Pang Yu entered, he was chattering and complaining to Lao Shi, who helped him change the dressing:

"Why do you say I'm so unlucky: everyone went out to travel together, but I had to get on this ghost boat later. Everyone went to the city gate to watch the excitement, but I was shot with an arrow in the ass! We all lived in this yard together, but I was stabbed by a guy when I went to open the door......"

"Be content if you can save your life, young man, you can still have antibiotics if you are injured now, and the next time anyone suffers such an external injury, I am afraid that I will have to wash the wound with strong salt water like the prisoners outside."

Doctor Shi stunned the little fat man with a casual sentence, he touched his belly, and imagined the ghost shouting and screaming from the courtyard where the prisoner was changing dressings every day, and he was a little palpitating.

"We're running out of medicine?"

The fat man was very nervous, he had never been confident in his luck, and it was very likely that he would be the one who needed medicine next time.

"A little more, but not much."

"Isn't there an infirmary on board?"

Pang Yu happened to hear this sentence when he walked in the door, so he casually asked - he had just sorted out the infirmary with Jack two days ago, and remembered that there was still some stock in it.

And Lao Shi raised his head impatiently:

"The infirmary does have some reserves in it, but sooner or later they will run out. In the past few days, we have consumed nearly one-third of the antibiotics on Xiao Liu alone - that foreigner's habits are too bad, and he uses drugs lavishly. In fact, there is no need to hit such a high unit here, but it is easy to develop resistance...... When the western medicine is used up, see how he catches the blind. ”

"So you're planning ahead?"

Pang Yu said with a smile - Lao Shi was holding a copy of the 95th edition of the "Color Atlas of Chinese Medicine in the Pharmacopoeia of the People's Republic of China" in his hand.

"There's no way, do you follow the customs. Speaking of Lingao, it is also a county seat, and there is not even a smart doctor. I'd like to find someone to ask for advice on TCM theory. ”

"Isn't there a Chinese medicine shop here, how can there be no doctor?"

Pang Yu was surprised, and Doctor Shi raised his head again and looked at him with disdain:

"Do you know the separation of medicines? Ximenqing's family also runs a crude medicine shop, but have you heard that he can practice medicine? ”

The other two people in the room were stunned for a moment, and then they couldn't help but laugh - this guy surnamed Shi was a bit dark-bellied, and often put on a poker face, but he told some bad jokes seriously.

Of course, the only one who could laugh out loud in the end was Pang Yu, and the poor fat man Liu covered his stomach very hard and didn't dare to make a sound, lest he burst his wound.

Holding his stomach all the way, Pang Yu finally came to the destination of his trip - the arsenal house. This house was originally a large warehouse, and of all the houses in the compound of the county warehouse, this room was the largest and of the best quality, that is, it was basically free from rain, so it was used to house the most valuable property of the people - a complete set of gun-making tools, small machine tools, and generators.

It is rightly called an arsenal. At this time, Engineer Xu Hui was sitting at the workbench, his eyes were bloodshot, and dozens of drawings were scattered in front of him, with many numbers smeared on them. Although Pang Yu couldn't read those parameters, he could make out those discarded patterns - all cannons, all kinds of artillery!

Ever since he talked to Xu Hui that night, the respectable technician has been working day and night, but there seems to be little progress. Seeing Pang Yu walk in, Xu Hui casually handed him a piece of paper, on which was a bunch of numbers, but the poor architect couldn't read anything.

"Hey, Pang Yu, the key is to manage the material. Without a metal pipe with sufficient strength, no matter how full my theoretical calculations are, I can't get the real thing. ”

Engineer Xu seemed very frustrated, and in the past few days, everyone had searched all the cargo positions on the ship, but they could not find a suitable metal pipe suitable for the barrel. The pipes used to make gun barrels have extremely high requirements for metal strength, and ordinary civilian metal pipes cannot meet this standard in terms of thickness and strength. It's not like a gun barrel, which can be replaced by a water pipe.

If you want to make steel and make guns from scratch, the workload is too large.

Pang Yuzhi didn't seem very disappointed, in fact, he came here this time to have an idea.

"Well, XCMG, I think I've found a replacement......"

Dragged Xu Hui, the two rode bicycles to the beach and boarded the passenger boat again. Pang Yu led the person to the bottom cabin and pointed to a row of round metal cylinders:

"Well, can this thing be used to craft artillery?"

Xu Hui's eyes widened suddenly, they were a few empty oxygen cylinders, I don't know how long they had been thrown here, the surface was a little rusty, but the top of the head was big, and it belonged to the standard industrial oxygen cylinder.

"We have metal welding and cutting equipment on the ship, can we use it as a gun barrel if we cut off one end of the bottle?"

Pang Yu is a layman, but the layman has the advantages of the layman - he has no prejudices and is more open-minded. In Pang Yu's opinion, the cannon is a round metal cylinder, and the oxygen cylinder is also of this shape, at least it looks like it, doesn't it?

Xu Hui circled around the bottle twice and smiled.

"It's a bit reluctant to make a cannon with this thing, the outer diameter of the volume bottle in this standard is 219mm, and the inner diameter should be 209. This caliber is definitely a large-caliber heavy artillery in artillery, but its length is only 1500mm, and there is only one meter three left after cutting off the shoulder of the valve mouth, and the double diameter is not even 7, so it has no range. Moreover, the nominal working pressure of standard industrial gas cylinders is 15MPa, and the allowable pressure can reach 18MPa, and the instantaneous chamber pressure of ordinary artillery is definitely higher than this. ”

A series of professional names made Pang Yu's eyes straighten, but before he could be disappointed, Xu Hui, a stinky old man who loves to sell guan, finally added:

"But if you really want to do it, it's not impossible. Anyway, we do not pursue over-the-horizon strikes, and there is a type of cannon that does not require high diameter and bore pressure...... As long as I can throw explosives out, I can make shells. ”

The two dragged an oxygen cylinder back to the arsenal, and pulled Huang Jiancheng, a technician engaged in metal smelting, Xiao Lang, Qin Shiqing, a technician engaged in machining, and Ma Qianshan, who was relieved from the military group, to discuss the possibility of using oxygen cylinders to modify cannons.

Xiao Lang shook his head as soon as he saw this bottle, he was a professional in machining, and he was able to skillfully operate various commonly used machine tools (turning, milling, planing, grinding, drilling, pulling, inserting), because he had worked in the machine repair for several years, even the more remote gantry planer, guide rail grinding, and vertical lathe would also be pointed, and there was a set of medium-sized machine tools on the ship, because the energy problem had not been solved and had not been unpacked. But to process artillery, this young man's opinion must be indispensable.

"Where can I use the bottle now, I have seen a lot of processing this kind of scrap cylinder in the past few years, and I want to cut corners and make it thinner than paper, and the pressure bearing capacity is definitely not enough. Besides, the double diameter is too low......"

These mechanical people seem to have cannon plots, and they are casually a string of nouns, which makes Pang Yu very depressed.

"He***, one by one, is now running to be an expert, what he did before, I have to worry about it......"

He simply ignored the frizzy fellow and turned to look at the old horse. Whether this cannon can be used or not, the old horse and Ma Qianshan have the best say -- he himself retired from the artillery unit, and he has been a soldier for seven years and has played artillery for five years, and he will definitely have to take people to operate the cannon in the future.

Lao Ma had been looking at this bottle from before, stepped forward and knocked on the bottle, listened to Pang Yu's words, and nodded without thinking about it:

"Okay, why not, I think the artillery seniors of the Eighth Route Army were even more humble than this, and they still made a loud artillery. It doesn't matter if the double diameter is low and the chamber pressure is low, let's make a mortar. ”

"Mortars of 209mm caliber?"

Xiao Lang was incredulous, and Xie Xi sneered next to him:

"What's not to do, during the Huaihai Campaign, even gasoline barrels could be transformed into cannons - have you ever heard of the famous 'cannon without conscience'? Being good at using local materials is a great tradition of our army's ordnance industry. ”

"The key is the shell, as long as the shell can be thrown at the enemy's head, it doesn't matter what means of projectile are used."

The old horse was very expert and casually drew a parabola diagram on the ground.

"The artillery is rudimentary, and at most I have more trouble calculating the trajectory, and the ruler is more complicated."

"Can it work? I've heard of no conscience cannon, that thing is almost accurate, and it doesn't matter where it hits. That's why it got the nickname. ”

Xiao Lang was still very worried, and the old horse smiled and patted him on the shoulder:

"You can not believe me, but you definitely have to believe the training course of the Hefei Artillery Academy of the Chinese People's Liberation Army. High-angle projectiles are our army's specialty, and our army's first gunner, Zhao Zhangcheng, is famous for his use of mortars. ”

The future gunners said so, and Xiao Lang had no choice but to shut up. So the matter was decided, and under the leadership of Engineer Xu, several mechanical mechanics began to trial produce the first mortar of the Ming Dynasty - the Super Great Force, which reached a caliber of 209mm.
