After leaving the training ground, I stopped by the ward to visit the injured Xiao Liu. The wound on the little fat Liu Mingqiang’s stomach has begun to scar, which is a good sign.

"You are so lucky. With such a serious wound and under such simple care conditions, no complications occurred."

The foreign doctor Jack was originally very happy with Xiao Liu's "good luck", but Lao Shi, another local doctor in Chuanzhongli, disagreed:

"What luck? Bacteria in this era have no resistance at all. We gave him so many antibiotics, so it's strange that he could get infected."

Lao Shi's full name is Shi Yisheng - he is born to be called a doctor. He majored in clinical medicine at Fujian Medical University. After graduating, he has been engaged in surgery for three years, focusing on trauma surgery. However, this guy has been hiding in the "ordinary" field before.

Among the "labor force" crowd, some refused to take the initiative to explain their majors, saying that they did not want to see bloody scenes again.

Of course, they were eventually found out. Doctors are always welcome, especially surgeons. Although there were no serious injuries to the time travellers, there were many seriously wounded among their prisoners. Jack alone would definitely be too busy.

came, so Dr. Shi had to hold his nose and walk among the blood again.

Of course, the captured prisoners have no right to enjoy modern medicines, but the doctors trained by domestic medical schools must have studied traditional Chinese medicine, and they know a little bit about classics such as "Compendium of Materia Medica". Use the herbal medicines found in the herbal medicine shops in the city, plus scientific

Using his own bandaging, disinfection and nursing methods, Lao Shi was able to save several lives from the Lord of Hell, and was very grateful among the captives.

But in private, Lao Shi told everyone - he was practicing with those prisoners.

Xiao Liu's energy improved a lot. When Pang Yu came in, he was chattering and complaining to Lao Shi, who was helping him change his dressing:

"Why do you think I am so unlucky: We all went on a trip together, but I had to board this ghost ship late. We all went to the city gate to watch the fun, but I got an arrow shot in my butt! Everyone

We live together in this courtyard, but when I went to open the door, I got stabbed..."

"Just be content if you can save your life. Young man, you can still use antibiotics for your injury now. Next time whoever suffers such an injury, I'm afraid they will have to wash their wounds with strong salt water like the prisoners outside."

Dr. Shi's casual words stunned the little fat man. He touched his belly and imagined the ghosts and ghosts that came from the prisoner's yard when the dressing was changed every day. He felt a little nervous.

"Our medicine is almost out?"

The fat man was very nervous. He never had confidence in his luck. 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 the ship?"

Pang Yu happened to hear this sentence when he walked in, so he asked casually - he and Jack had just tidied up the infirmary two days ago, and remembered that there were still some stocks in it.

Lao Shi raised his head impatiently:

"There is indeed some reserve in the infirmary, but it will be used up sooner or later. In the past few days, we have consumed nearly one-third of the antibiotics on Xiao Liu alone - the foreigner has such bad habits that he cannot use the medicine

Come and spend a lot of money. In fact, there is no need to attack such high-level units here, but it is easy to develop drug resistance... When the western medicine is used up, we will see how he is blinded."

"So you're planning ahead?"

Pang Yu smiled and said - Lao Shi was holding a 1995 edition of the "Color Atlas of Chinese Medicines in the Pharmacopoeia of the People's Republic of China" in his hand. In the past few days, he had been holding this book while eating and sleeping, focusing on studying it.

"I have no choice but to do as the Romans do. Speaking of which, Lingao is considered a county town, but I can't even find a good doctor. I also want to find someone to consult on the theory of traditional Chinese medicine."

"Isn't there a Chinese medicine shop here? How could there be no doctor?"

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

"Do you know about the separation of medicine? Ximen Qing's family also runs a herbal medicine shop, but have you ever 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 burst into laughter - this guy named Shi was a bit sinister, and he often put on a poker face, but told some cold jokes in a serious manner.

Of course, only Pang Yu could laugh in the end. Poor Fatty Liu held his stomach very hard and did not dare to make a sound, for fear of bursting the wound.

Holding his stomach in his arms all the way, Pang Yu finally arrived at the destination of his trip - the arsenal house. This house was originally a large warehouse. Among all the houses in the county warehouse compound, this house has the largest area and the best quality -

—that is to say, it is basically watertight, so it is used to house the most valuable possessions of the people at the moment - a complete set of gun-making tools, small machine tools, and generators.

This place was naturally called an arsenal. At this time, Engineer Xu Hui was sitting at the workbench, her eyes bloodshot. Dozens of drawings were scattered in front of her, with a lot of data daubed on them. Although Pang Yu couldn't understand those

Parameters, but you can identify those abandoned patterns - they are all cannons, all kinds of cannons!

Since talking to Xu Hui that night, this respectable technician has started calculations day and night, but there seems to be no progress. When Pang Yu walked in, Xu Hui handed him a piece of paper, and on it was

A bunch of data, but the poor architect can't understand anything.

"Hey, Pang Yu, the key is the material of the body tube. Without a metal tube with sufficient strength, my theoretical calculations will not be able to produce a real thing."

Engineer Xu seemed very frustrated. In the past few days, everyone had searched all the cargo warehouses on the ship, but could not find a metal pipe suitable for use as a cannon barrel. The pipe used for the cannon barrel requires extremely high metal strength. Ordinary civilian metal pipes, regardless of thickness,

Still, the strength doesn't meet this standard. It's not like a gun barrel, which can be replaced by a tap water pipe.

If you had to make steel and cannon from scratch, the workload would be too huge.

Pang Yu did not seem disappointed. In fact, he came here with an idea.

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

Dragging Xu Hui along, the two rode bicycles to the beach and boarded the passenger ship again. Pang Yu took the people to the bottom cabin and pointed to a row of round metal cylinders:

"How about this? Can this thing be used to process artillery?"

Xu Hui's eyes suddenly widened. They were several empty oxygen bottles. She didn't know how long they had been left here. There was some rust on the surface. They were no bigger than a head and were standard industrial oxygen bottles.

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

Pang Yu is an outsider, but an outsider has the advantage of being an outsider - he has no prejudices and has a more open mind. In Pang Yu's opinion, the artillery is a round metal cylinder, and the oxygen bottle is also in the same shape, at least it looks similar, right?

Xu Hui circled the bottle twice and laughed.

"This thing is a bit reluctant to make a cannon. The outer diameter of this standard medium-volume bottle is 219mm, and the inner diameter should be 209. This caliber is definitely a large-caliber heavy artillery gun, but its length is only 1500mm. Cut off the valve mouth of the bottle

The shoulder is only 1.3 meters long, the diameter is not even 7, and it has no range. Moreover, the nominal working pressure of standard industrial gas cylinders is 15Mpa, and the allowable pressure can reach 18Mpa. The instantaneous chamber pressure of ordinary artillery is definitely higher than this.

.”

A series of professional names made Pang Yu's eyes go straight, but before he could feel disappointed, Xu Hui, a stinky old man who loved to sell off, added one last sentence:

"But if we really want to do it, it's not impossible. Anyway, we don't pursue beyond-visual-range strikes. There is a kind of gun that doesn't require high diameter and chamber pressure... As long as it can eject explosives, I can make artillery shells.

OK."

The two dragged an oxygen cylinder back to the arsenal, and brought over Huang Jiancheng, a technician engaged in metal smelting, Xiao Lang, Qin Shiqing, a technician engaged in mechanical processing, and Xi Ma Qianshan, a commander from the military organization, and they all discussed using oxygen cylinders to modify it.

The possibility of artillery.

Xiao Lang shook his head when he saw the bottle. He is a mechanical processing professional and can skillfully operate various commonly used machine tools (turning, milling, planing, grinding, drilling, pulling, and inserting) because he has worked in machine repair for several times.

In 2006, he could even do the relatively uncommon gantry planing, guide rail grinding, and vertical lathe. There was a set of medium-sized machine tools on the ship, which had not been unpacked because the energy problem had not been solved. However, this young man's opinion was definitely indispensable when it came to processing artillery.

"How can today's bottles be used? I've seen a lot of this kind of scrap steel bottles being processed in the past few years. They cut corners one by one and wanted to make them thinner than paper. The pressure-bearing capacity of the chamber is definitely not enough. Besides, the diameter is too low..."

These mechanical people seemed to have a cannon mentality, and they just used a bunch of nouns casually, which made Pang Yu very depressed.

"They ***, all of them are here to show their expertise. I have to worry about what they did before..."

He simply ignored this irritable guy and turned around to look at Lao Ma. Whether this cannon can be used, Lao Ma Qianshan has the best say - he himself retired from the artillery unit and served in the army for seven years.

He has been building artillery for five years. In the future, when the cannon is built, he will definitely have to lead people to operate it.

Lao Ma had been looking at this bottle for fun before. He stepped forward and knocked on the bottle. After listening to Pang Yu's words, he nodded without thinking:

"Okay, why not? I think the artillery seniors of the Eighth Route Army were even more primitive than this back then, and they were still able to produce artillery that fired loudly. It doesn't matter if the diameter is small, the bore is small, or the pressure is low. Let's just make mortars."

"209mm caliber mortar?"

Xiao Lang couldn't believe it, and Xie Xi sneered beside him:

"What's wrong? During the Battle of Huaihai, even gasoline barrels could be transformed into cannons - have you heard of the famous 'heartless cannon'? Being good at using local materials and using crude materials is a fine tradition of our military's military industry.

"

"The key is the cannonball. As long as the cannonball can be thrown at the enemy's head, it doesn't matter what projectile method is used."

Lao Ma was very expert and drew a parabola diagram on the ground.

"The artillery is as simple as it gets. At most, I have to have more trouble calculating the ballistics, and the ruler is more complicated."

"Is that possible? I've heard of heartless cannons. Those things are almost impossible to hit. That's why I got this nickname."

Xiao Lang was still worried. Lao Ma smiled and patted him on the shoulder:

"You don't have to believe me, but you must definitely believe in the training courses of the Hefei Artillery Academy of the Chinese People's Liberation Army. High-angle projectiles are our army's specialty, and our army's top artilleryman Zhao Zhangcheng made his name with mortars.

"

The future gunners all said this, and Xiao Lang had no choice but to shut up. So the matter was settled. Under the leadership of Engineer Xu, several mechanical technicians began to trial-produce the first mortar of the Ming Dynasty-a super mortar with a caliber of 209mm.

Great force.
Chapter completed!
