When she got up early the next morning, when she was washing, Yunmo came in with a box and said that it was given to her by the prince. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

Guo Wenying opened it and saw that it was a white hosta, or not a hairpin, but two hairpins twisted together with gold and silver wires to make a hairpin. Two hairpins stand side by side, the same thickness, only one is longer, the other is shorter, and if you pull the hair at the same time, even if you pull one out, the hair will never fall apart again. It's just that the workmanship of the skein is a little rough, and it seems to have been done in a hurry.

Yunmo said: "This is what the prince made for the adults overnight last night, the prince said that his craftsmanship is not good, so let the adults make do with it, and when he returns to the capital, he will find a skilled craftsman to make a suitable one for the adults." ”

Guo Wenying was a little stunned, this was actually made for her by Feng Jingting himself?

She watched it for a long time and was not half moved, but she was a little suspicious of someone's motives, that master's character is really not like a gratuitous payment, is this holding back what is bad?

After thinking about it, he still took it and forgot it, anyway, he was calculating her all day long, and he didn't care about it anymore.

After breakfast, he left the camp and was ordered to go to the prison office.

The supervision office of the Northwest Army is the 'crystallization of love' that Feng Jingting has been operating for several years, and it has the meaning of being raised as a son. From the beginning of the construction, a huge amount of money was invested in it, from the construction of the house to the mining of iron ore, it was all handled by him, and it was really painstaking.

In other people's words, Guo Wenying's brain is naturally different from others, and what cumbersome weapons are designed, and he is even more proficient in the art of forging, and every innovation is surprising. Under her management, the supervision department has become quite large-scale in just a few years.

It's a beautiful day, the wind is beautiful, and even the air is warm and sweet. Guo Wenying was also in a good mood, so she rode a horse, didn't even bring her own guards, and went to the supervision office alone.

Although this place is not located in the northwest camp, it is not too far away, but the road is not easy to walk, and there is a Nine Palace Maze at the entrance. It was planned and arranged by Feng Jingting himself. Feng Jingting is also quite talented, not only proficient in military books and battle strategies, but also very good at various formations, although it is an ordinary Nine Palace Array, but it has added a lot of evolution, if people who don't understand it can't turn out for three days and three nights.

Everyone knows that private military construction, manufacturing weapons is a big crime to kill the head, in order to conceal, on weekdays here is not allowed to enter and exit at will, and there is no one to see after walking for three miles. Guo Wenying rode through the formation, walked through a place of flowers, and saw black smoke coming out of the boiler from a distance.

She couldn't help frowning, although this place is hidden, but this smoke can't be covered no matter what, if it continues like this, it will become a disaster sooner or later, and then Feng Jingting will be unlucky, and he will be unlucky. The reason why it has not been discovered for more than three years should be that the hands of those people in Beijing have not yet reached here, but it is also fast, once this battle is fought, as soon as the guns and artillery appear, they can no longer hide it.

How can we think of a way to make this place legal?

Thinking in her heart, the people had reached the mouth of the valley, and the soldier who guarded the gate knew her very well, and came from a distance to lead the horse.

A school captain ran over, and shouted from afar: "Master Guo, you are here, we are waiting for you to come over with the stars and the moon." ”

Guo Wenying jumped off the horse, "But there is a problem with the artillery superintendent?"

"That's not it, adults are our backbone, we can't see people, we panic, and we don't have the energy to work. ”

Guo Wenying: "......"

This Captain Zhang's kung fu is really high-pole, she has to learn, she has to study hard.

Captain Zhang Xinfang respectfully invited Guo Wenying in, and the two shuttled between various workshops, listening to the foreman introduce the progress of each workshop from time to time.

The war is imminent, and the weapons and equipment must keep up, so before coming, Guo Wenying drew up a list and listed the required swords, arrows and other things. At this time, he handed it to Zhang Xinfang, "It's ready within a month, no problem." ”

Zhang Xinfang looked at it, with a look of embarrassment, "Time is so tight, I'm afraid it's not easy to do." Especially a few days ago, the adults took away a lot of explosives, and it will take time to distribute them now, and I am afraid that it will be difficult to get out of the fire barrels and cannon barrels in the list. ”

"It's okay to have a fire cannon, that thing is not very useful except for fire prevention, the cannon barrel must be prepared, and the artillery, how is it being built so far?" Guo Wenying said and looked at a few cannon barrels stacked on the side of the wall, the speed was still slow!

Zhang Xinfang said: "At present, four artillery pieces have been built, and six more are in the process of being built, and ten should be built in a month." ”

Guo Wenying nodded, "Ten doors are ten, be sure to make all the weapons within a month, not for one more day, tell the workers to hurry up and tell them to sleep less." After a month, they are idle. ”

Zhang Xinfang was surprised, "Will the war be over in a month?"

Guo Wenying didn't speak, I'm afraid that in a month, this supervision office will no longer exist.

Zhang Xinfang didn't know what she meant, and he didn't dare to ask more, so he just said, "Do you want to go to the firearms workshop to have a look?"

She nodded, "Lead the way." ”

Although a lot of effort was put into the construction, the firearms workshop built in the mountains still looked a little rough, and most of the houses were made of stone, quarried from the mountains, and built on the spot, with only a few pieces of wood interspersed in them, all to support the beams and prevent the stone houses from collapsing. There were seven firearms workshops, the largest of the entire Inspectorate, and a huge stone storehouse, covered with many tarpaulins, sprinkled with lime, all of which were used to protect against moisture.

It is strictly forbidden to light lamps and fires in the entire supervision office, and no fire is allowed in the kitchen, and every day meals are brought in from outside the mountain, which increases the risk of detection, but there is nothing to be done in a place full of gunpowder. Gunpowder is the most avoidant of fireworks, once ignited, the entire supervision office is like a huge explosive bag, I am afraid that the whole mountain will be blown up.

The smell of gunpowder was everywhere in the workshop, and more than two dozen craftsmen were immersed in filling ammunition for guns and artillery.

Before Guo Wenying designed the new cannon barrel, the Kyoto Supervision Bureau and the Ordnance Bureau also had artillery, but the early artillery manufacturing was made of mud as a casting mold, and the mud mold had high requirements for humidity, soil composition, and casting technology.

The mud mold is disposable, the success rate is low, and it is inevitable to have trachoma, and the barrel is also uneven, which is very easy to blow up, and needs to be used after polishing, and the process is quite cumbersome.

Relatively speaking, the iron fan casting barrel is better, with iron as a mold, the mold can be reused, the cast gun chamber is naturally smooth, less trachoma, and the quality is high. However, this requires a high level of technology, and the iron must be able to cool quickly, and Guo Wenying spent a long time researching and finding a water-cooled self-tightening method to solve this problem.

Water-cooled self-tightening is to let the cannon that has not been cooled in casting start to cool from the inside, so that the artillery has a force from the outside to the inside, which is equivalent to wrapping an iron hoop around the whole body of the gun, so that the gun can withstand higher chamber pressure, and the charge is increased The iron fan and the water-cooled self-tightening are combined, and the iron fan in the gun chamber is made hollow, and water is added to it.

In her previous life, she was a fan of weapons, and she studied engineering, and in this era, with the guidance of famous teachers, she understands it a little faster than others. Others say that she is a genius, only she knows, genius is not genius depends on where you come from, she at most just sees more than others, and sees more.
