Along the soft mud path, a group of people walked into a nearby waterwheel hut like a stroll. Where the scattered footprints stepped on, some newly sprouted weeds lay groaning in the foot sockets with difficulty...

Due to the lack of building materials such as lime, the path outside the waterwheel hut was only covered with a layer of rare loess and sprinkled with water. When the workers started working, some pebbles from the river would be quarried and spread on the mud floor.

Li, it becomes a road.

The conditions are difficult, so no one cares about these trivial things.

After rubbing the mud off the soles of their shoes on the threshold of the waterwheel hut, everyone walked into the house and saw a wooden rifling machine.

The rifling machine is naturally the type used in the original ordnance workshops. The wood used for the rifling machine is relatively hard catalpa wood, elm wood, and some jujube wood, which are all hard woods.

The position of the large turntable that originally required manual rotation was replaced by a small gear turntable. The waterwheel was creaking outside, and the main shaft of the waterwheel drove a transmission shaft straight into the house, and then through several groups

The transmission gear changes the rotation speed and ultimately brings a steady stream of power to the rifling machine.

What surprised Hu Changyi was that these transmission gears were also made of wood and looked somewhat fragile.

However, considering that rifling does not require much cutting, these wooden transmission wheels can be understood. After all, the processing difficulty of wooden gears is much simpler than that of steel gears, and the materials are easier to obtain.

.Yes, saving money is the key point.

There is no special pavement outside the small waterwheel workshop, but there is a layer of stone pavement inside the house. There is even a wooden work frame and workbench placed on one side of the rifling machine. Hu Changyi shook it deliberately

After a while, it’s very strong!

"How's it going? Everyone has put a lot of effort into designing this small house! There is a waterwheel with a machine, and four workers can work together in the house. Look at this workbench. The qualified gun barrels have been cut and placed here.

, the semi-finished products are placed here, and the scrap products are placed on the shelf here waiting for secondary processing!"

Minister Zhang looked at Hu Changyi and proudly introduced to him the equipment arrangements in the waterwheel hut. Needless to say, just from Minister Zhang's expression, he knew that he was indispensable among the people who designed this hut.

"It's very good! It's really good! And I think this house has good lighting and good ventilation. Now I don't feel hot when I stay in the house!" Hu Changyi is also very satisfied with the design of this cabin.

"Hahaha, of course! When the surrounding willow trees grow up, this hut will also be covered, which will make it cooler! And the light is strong in summer, even if the trees are shaded, the house can still be seen! As for the

In winter...the water channels are frozen, so nothing can be done!" Minister Zhang said with a smile.

"You are right! But to be able to utilize natural resources to this extent is probably the ultimate!" Hu Changyi said with a thumbs up.

"Haha, that's right! After reading this, our next stop is to go to Huanglong Cave! Our bullet machine has been put in and installed, and we are just waiting for debugging to complete trial production! I think you kid should be anxious too, right?"

Minister Zhang said.

"Of course I'm anxious! Without bullets, no matter how many guns you make, it's useless! That's the key point!" Hu Changyi nodded.

After hurriedly viewing the remaining waterwheel hut workshops, the group followed the mountain path and arrived at the location of Huanglong Cave.

From a distance, the entrance of Huanglong Cave seems to be much smaller, and there seems to be a large platform in front of the cave. There is also a lifting platform built with pulleys and iron frames on the platform.

But what makes Hu Changyi strange is that there is no ladder to go up in front of Huanglong Cave. This is a place 20 meters above the ground. How can people go up without a ladder? Fly up? And how do you get all the equipment in?

While Hu Changyi was confused, everyone had already reached the Huanglong Cave. Only then did Hu Changyi find out where the stairs going up to the cave were. On the west side of the platform, a straight up and down wooden ladder with a guard ring was erected there.

.

Every four meters the wooden ladder rises, there will be a small platform on the side for people to rest. The lifting platform of the pulley block is on one side of the ladder, which just blocks the wooden ladder.

"Speaking of which, you really posed a problem for everyone back then! It took a lot of effort to bring so much supporting equipment into this cave!" Minister Zhang stood under the platform and raised his head to look around the platform.

The walls were built up layer by layer, and he said with some emotion.

"It's not easy to do! And we also reinforced the outer layer of stones. Isn't it a lot of work?" Hu Changyi asked.

"Haha, it can't compare to the Great Wall! But in order to get the equipment in, everyone first carried earth and piled it up under the cave to create a slope. Then they stepped on it firmly, laid wooden tracks, and used pulleys to set up on the wall of the cave.

, everyone delivered the equipment one by one!”

"After the equipment was delivered, the earth and rocks were used on site to build this large platform, and the outer layer was protected with strips of stone! Just to build this wall, we used a lot of lime cement!

"

"Oh, what you see is just the outside. In fact, there is some space inside the platform. There are two in total. There is a solid firepower point hidden at 7 meters high and 15 meters high. Inside this firepower point, you can put three

There is a machine gun group inside, which is exactly a link in the frontal defense system of the cave!"

As Minister Zhang spoke, he raised his head and looked at the cave in the sky, with a rather emotional tone in his voice.

"Thank you to the comrades who have worked hard! You said it is easy, but if you really do it, this will not be an easy job!" Hu Changyi calculated the amount of earthwork needed and knew that it was definitely a big project these days.

"Yes, in order to build this, we sacrificed eight of our engineering soldiers!" After Minister Zhang finished speaking, he took off his hat and lowered his head.

"Salute..." Hu Changyi did not ask how those soldiers died. What he did was to lead Li Yuexuan and others to salute the mountain wall in front of them to pay tribute to the comrades who had sacrificed their lives.

Time seemed to freeze as everyone saluted, and even the surrounding mountain wind seemed to have stagnated. A full three minutes later, Minister Zhang put on his military cap and pointed his body at Hu Changyi and the others.

"Okay, let's put it down! The efforts of comrades are not in vain! At least, we have our own bullet production workshop, which will be able to solve a large number of ammunition sources in the future! Moreover, this workshop has three floors
Chapter completed!
