Taking off the ribbon, Yuan Fang stroked the screw buckle with his fingers and said, "The effect is good, now wait for the materials to be shipped, and everyone will work harder." ”

At midnight that day, the convoy arrived at Long Roundabout on time, and a large number of copper ingots were loaded onto horse-drawn wagons at the docks and sent to the blacksmith's furnace, as well as silk, but not for bunching, but for the protective layer on the outside of the fuse.

The fire of the blacksmith furnace had reached its peak, and the copper ingots were melted and poured into the mold, and Yuan Fang waited anxiously.

The mold was opened, and the orange-yellow shell cover appeared in front of Yuan Fang's eyes, cooled down, buckled, and then installed on the top of the shell, which was tightly closed and perfect.

Yuan Fang slept for a day, and he was still very energetic at night, but Sang Rou and they couldn't, in the middle of the night, Xia Yi and Ye Qingru came to change shifts, Sang Rou and Jieyue had already fallen asleep together, and Yuan Fang was still busy with his hollow cannonball shells in high spirits.

It was another sleepless night, and the blacksmiths were already tired and depressed, so Yuan Fang kindly sent them back to rest, and asked Guan Xiaoyun to drive the carriage over to bring the fruits of this night's labor back to the studio.

On the way back, Yuan Fang was in a very good mood, whistling all the way, greeting anyone he saw from afar, and the soldiers who passed by were all inexplicable and hurriedly returned the salute.

When passing by the residence, Yuan Fang shouted: "Stop." Guan Xiaoyun was taken aback, and the reins in his hand almost fell off.

Stopping the carriage, Guan Xiaoyun turned around and asked, "Dean, what's wrong?" ”

Yuan Fang ignored Guan Xiaoyun and said to Ye Qingru and Xia Yi, who were also taken aback: "When you arrive, you two will go back to sleep first, and then Sang Rou and they will get up." ”

Ye Qingru shook her head and said, "No, I want to accompany my brother-in-law." ”

Yuan Fang glared and said, "Look at how tired you are?" If you continue to stay up like this, you will become a yellow-faced woman, listen to me, go back and sleep well, and then go to me when you wake up, no one will stab me here, besides, isn't there still Xiaoyun. ”

Guan Xiaoyun nodded vigorously: "Yes, there is still me." ”

Xia Yi pursed his lips and said, "It's just him, maybe I'll run away with the red clothes at some point, brother-in-law." ”

Yuan Fang waved his hand and said, "Okay, this is an order, don't you worry about Xiaoyun and Erniu, it's a big deal to let Erniu and them follow me." ”

In the past few days, staying up late with Yuan Fang, it is too much to sleep for three or five hours a day, Ye Qingru is indeed tired, in order to better protect Yuan Fang, Ye Qingru nodded, pulled Xia Yi off the carriage and went back to rest, just like Yuan Fang said, this is Changhuan Island, it is a naval base, and the possibility of an accident is negligible, and there are Tian Erniu and them, Yuan Fang's safety should be no problem.

Xia Yi looked at the sky and said, "Sister Qingru, hurry up and sleep, wait for those artillery to start firing artillery, and you won't be able to sleep when you want to." ”

Ye Qingru found two cotton balls and handed them to Xia Yi and said, "Wait a minute, plug your ears, you can be stronger." ”

Xia Yi pointed at Ye Qingru: "Sister Qingru, it turns out that you have been prepared." ”

Ye Qingru said proudly: "I learned it from the sisters on night duty, they all go out day and night, and there is no way to solve the problem of cannon sound, they can't hold on for a long time." ”

The carriage continued to walk towards the studio, Yuan Fang sat on the cart and smiled proudly, the reason why he let Ye Qingru and Xia Yi go back, first, he really felt sorry for them, let them go back and have a good rest, second, Yuan Fang also had a purpose, the shell casing was there, and the next thing was to fill the gunpowder and fuse, this work was quite dangerous, because Yuan Fang didn't know if the so-called copper lid and iron bullet case would rub sparks, Ye Qingru and Xia Yi both knew about it, if they were there, they would definitely not let Yuan Fang take risks, But someone has to do this job, and Yuan Fang doesn't want others to take risks for him, especially Ye Qingru and the others.

When she came to the studio, Tian Erniu took over Yuan Fang's escort work, and personally led people to guard Yuan Fang's side.

Gunpowder, fuses, and sealed rubber blocks are all ready-made, Yuan Fang drove Guan Xiaoyun away, asked him to go to the beach, check the situation of those cannons, to put it bluntly, just find an excuse to send him away, such a dangerous thing Yuan Fang of course will not let him stay, and Tian Erniu and a few of them, Yuan Fang also let them stay away.

Everything was ready, there was no one else nearby, Yuan Fang rubbed his hands and began to charge.

First of all, Yuan Fang opened the lid of a cartridge case, wiped it with a clean rag, and after making sure that there was no stagnant water and moisture in it, he scooped a spoonful of gunpowder and poured it into the cartridge case, looked at it, and continued, until Yuan Fang stopped filling most of it, how much gunpowder should this thing be filled? Yuan Fang had no experience, so he could only cross the river with a stone.

After thinking about it for a long time, Yuan Fang decided to try them all, so he first filled the first cartridge case, and then closed the lid with the long fuse inserted, and buried the fuse inside in the gunpowder place.

Next is the most dangerous work, Yuan Fang took a deep breath, held the lid with both hands and turned it carefully, just turned a little, Yuan Fang was already scared out of a cold sweat.

No, it can't go on like this, and if the shell doesn't explode, I guess I'll be paralyzed first.

What to do? Yuan Fang circled around the workbench several times, looking at the cannonballs that were only one step away from completion, and he was shocked and frightened.

At this time, Tian Erniu's voice came from outside the door: "Brother-in-law, the supply airship from the Chamber of Commerce has arrived, bringing a lot of silk, do you want to go and have a look?" ”

The sudden voice scared Yuan Fang into a thrill, and after listening to Tian Erniu's words, Yuan Fang's mind flashed: "Erniu, you take someone over to have a look first, I'll go over later." ”

Tian Erniu scratched her head, looked at the closed door and wondered, "Brother-in-law, what's wrong today." ”

Tian Erniu left, Yuan Fang found a thin strip of cloth to come back, he thought so, and used a thin cloth to pad the link between the cartridge case and the lid, so as to avoid friction between the two, causing sparks to ignite the gunpowder inside.

But when Yuan Fang returned to the workbench with the cloth strip and was about to do it, he stopped again, although this could prevent sparks when turning the lid, but the cloth seemed to have static electricity, and Yuan Fang was often electrocuted when he got off the taxi in the past. Yuan Fang didn't know what kind of situation could produce static electricity, he wasn't sure, so he couldn't take risks, he hadn't lived enough, and he didn't want to end up with no bones.

What to do, what to do, Yuan Fang was so anxious that he turned in circles. Calm down, Yuan Fang forced himself to calm down, found a box to sit down, took a deep breath, and then began to think, so copper and iron dry grinding is absolutely not good, silk is too risky to make cloth pads, so what else can be used?
