"I don't know if I can transfer the subordinate to the command of General Zhengxi."

"Why?"

I didn't think about it, I can't say that Xu Da is not safe there, so I can only find a lame reason.

"The Silk Road in ancient times, the lower officials yearn for it and want to follow the footsteps of their ancestors to appreciate it."

The good end of the war, I really thought that I was going to travel, Zhu Biao was speechless for a while, but everyone thought that it was foolproof, and the tourism was similar.

"This is when the palace goes to the palace, and I mention it to my father, the hope is not very big, and it is only right that you prepare early."

"Thank you, Your Highness, Your Highness won't bother Your Highness much, and I'll leave."

Zhu Biao has a lot of things, and he is not polite, nodding.

Zheng Xiong, who left the prince's mansion, didn't go to the Jiaofang Division anymore, and went back to the pharmacy directly, Zhu Biao had no choice, that is, there was really no good way,.

Let Wu Wei gather the people in the pharmacy, and in a short time, they will be fully assembled and tell the holy decree.

"Your Majesty ordered the pharmacy physician to follow the army on the expedition, and the official is in the ranks, so you should follow along, and take care of each other."

"You don't have to worry, my Ming Dynasty has always been destroying the ancient decay in the face of Meng Yuan, and this time it will definitely be the same."

Although Zheng Xiong gave a reassurance, following the army on the expedition was still an uncertain thing, and everyone couldn't help but worry.

There was a lot of gossip and discussions, and Zheng Xiong was not in a hurry, and let everyone talk to each other.

After a long time, he stopped talking and looked at Zheng Xiong.

Seeing that the discussion was over, Zheng Xiong accosted him.

"What's the matter, have you finished talking about it, if you have any opinions, questions, or can't get out of it, you can explain it to the official in advance now, and it will be registered in the register, and it will be too late for you to talk about it."

"Withdrawal, the doctors in the pharmacy have all withdrawn, and there is no rule of law for injuries and illnesses in Nanjing City, is it a group that needs to be left behind."

glanced at the person who spoke, it was a passerby doctor who was not up or down in the pharmacy, a member of the old oil, not brilliant or sharp.

"Well, the doctors of the Sifang Pharmacy have left two people behind, mainly responsible for catching medicines. In the case of surgery, Zhang Peng stayed, in charge of surgery, and the others who followed me followed. ”

"Draw, a small handful of old bones, can't withstand the long journey back and forth, please let the small one stay in the pharmacy, the little one is grateful."

It's still the same person just now, waiting here, and the inquiry is also paving the way for himself.

Zheng Xiong didn't answer and continued to look at everyone.

"If you have any other opinions, hurry up and answer them later."

"Draw, the little mother in the family needs someone to serve, and the little one can't leave, please forgive me."

"Hmm."

Seeing Zheng Xiong nodding, the rest of the doctors hurriedly spoke.

"Draw, the child's marriage is approaching, and he needs a small operation, and he can't get rid of it."

All kinds of reasons, strange, accounting for half of the crowd, the expedition is really hard, the long-distance travel and the accident of a sudden visit at some point, there are many people who are unwilling, not to mention these old oilers.

"Is there any, no, that's it, the reason they said just now is verified by Medical Officer Wu and Deputy Yang Drawn, this official hopes that it is true, if there is any deception, don't blame this official for giving you a charge of escaping."

Seeing that Zheng Xiong said resolutely, he who had just found a good reason began to change his tone again.

"Tieling, the little one remembers wrongly, he was called old by their nickname, but he just looks old, but in fact, he is only thirty, and there is no problem with the army."

"Yes, in fact, Xiao'er's marriage is handled by his uncle and brother, there shouldn't be any mistakes, and there is no problem with the little one in the army."

Zheng Xiong's words brought back half of them, and the rest was handed over to Wu Wei for verification.

"This time it's just such a thing, it's no problem just now, those who can run and jump follow the official, the rest of the old and weak, and those who can't get out, Medical Officer Wu counts, and finally hands it over to the official, as for who goes up and who stays, wait for the official to see if it's true."

This time, the future is uncertain, and the doctor in the pharmacy can't help but look sad.

Zheng Xiong hurried to the glass factory again, and prepared a weapon for self-defense, the gun is now available, the time is tight, the task is heavy, Zheng Xiong plans to get a few steel pipes, do a few guns to defend himself.

The range of the existing firecrackers is not far, probably between tens of steps and two hundred steps, mainly due to the limitations of materials.

The principle of guns and cannons is not difficult, especially the front-loading gun, which is essentially a steel or copper pipe, sealed at one end and left with a hole at the other end for the bullet to fly out.

The steel pipe is definitely enough at this time, and all Zheng Xiong did was to get a weapon to defend himself.

The steel pipe was enough, and Wang Zheng was instructed to buy some 100 steel and some lead powder through a special procurement channel, as well as the necessities for gunpowder production, and then Zheng Xiong continued to say to Wang Zheng.

"The glass that is being smelted now is finished, don't make it again after that, this official is useful."

The melting point of steel is 1,500 degrees, and the temperature of glass is more than 1,000 degrees.

"Another mold is cast, the pipe style, one end is seamless, and the other end is left with a hole."

After instructing Wang Zheng, Zheng Xiong waited quietly.

When the steel and lead powder were ready, the glass factory began to smelt the steel, and the ready-made steel was recast, and the process was much easier.

The heat of melting molten steel is still not big, so you can only use coal to increase the blast, as for whether the furnace built can withstand it, Zheng Xiong doesn't care so much.

After some operation, the steel pipe is formed, and many things are ready-made and ready to use.

However, the cast steel pipe was a little flawed and a little pitted, Zheng Xiong first ordered it to be polished, and then made gunpowder.

One nitrate, two sulfur and three charcoal, the best ratio of black powder, 75% nitrate, 10% sulfur, 15% charcoal.

The employees of the glass factory were instructed to crush the nitrate, sulfur, and carbon they bought, and then weigh them on a small scale with high precision and mix them together.

This is black powder, the best ratio of mature black powder, otherwise there will be more or less, and the effect of fireworks will be set off.

Then the barrel was brought over and the employees of the glass factory were asked to make some ammunition of the same caliber and size out of lead powder.

Then, before the experimental charge, Zheng Xiong also got some water to wet the gunpowder to make granular gunpowder, whether it is transportation or combustion, granular gunpowder has more advantages, compared with traditional gunpowder, between one and three times.

Just a steel pipe, there is a small hole in it, pour gunpowder, compact it with a whole strip, then put lead bullet to plug tightly, and then put ignition powder in the small hole made in advance.

Open the fire fold, ignite the ignition, and with a bang, the lead bullet quickly disappears like a wild horse.

It took them a long time to find it.

At a distance of several hundred paces, buckshot was found.

Looking at the steel pipe in Zheng Xiong's hand, everyone in the glass factory looked uncertain, this inconspicuous thing was even better than a fire gun.

However, with the fire gun Zhuyu in front, the current steel pipe is only more powerful than the fire gun even if it is blessed with black powder.
