"The effective firing distance of our valley rifle is 200-300 meters, but the average person can aim at most to ensure the shooting accuracy of 200 meters, now the soldiers are not training long enough, the loading speed is not fast enough, it is very good to be able to load the bullet in 5 seconds after shooting, 150 meters away from the gun, the enemy can run out of 30 or 50 meters after five seconds after scattering and escaping, which also causes us to only fire about two shots on average and must start to disperse the pursuit." Ji Xinyu continued.

Chen Yu thought for a while and said: "Young Master is right, although we have a valley-style rifle, we are not skilled enough in the use of the gun, and the impression of the original battle formation has not been changed, so this situation has been created. In the future, we will strengthen the training of soldiers' gun proficiency, and then study some combat methods using valley-style rifles, so as to live up to the young master's gun. ”

Before this, many soldiers did not have a proper attitude towards the valley rifle, although they felt very powerful, but the thoughts in their bones made them just treat them as high-end toys like firearms, after this battle, their understanding of the valley rifle should rise to a higher level.

The battle ended quickly, the pirates left a corpse, and the looted things were also thrown on the way to escape, and after chasing for half an hour, Chen Yu recalled the team and began to clean up the battlefield, Ji Xinyu did not participate.

After the battlefield was cleaned, Chen Yu reported that the bandits shot 38 pirates, captured 5 injured pirates, and the villagers were basically robbed of food and materials, but a small amount of silver was robbed.

When he returned to Yeongcheon Mansion with the corpses captured and killed by the pirates, the nearby villagers lined the road with unprecedented cheers when they saw the killed and captured pirate villagers.

Before this, when encountering a pirate attack, you can only wait until the pirates are finished killing and retreating on their own, and there are very few times that you can repel pirates head-on, let alone kill so many, even if the soldiers of the guard come to suppress the bandits, they are all pretending, no one will fight with their lives, every time the bandits are scared away, even if they are meritorious, they can kill a few people even if they are a great achievement, this time the pirate corpses alone are piled up with two or three board cars, and there are prisoners behind, how can the villagers who have been ravaged by the pirates for many years not rejoice.

The villagers saw hope, this Lingchuan Mansion could protect them, the treatment of the displaced people in Lingchuan Mansion had made the surrounding villagers envious, and with this crackdown on bandits, the villagers had a deeper sense of identity with Lingchuan Mansion in their hearts.

Ji Xinyu called Futian Village Zheng over and asked Village Zheng to count the materials lost by each family and collect them in Lingchuan Mansion, and the villagers were even more grateful, strictly speaking, those were already considered the spoils of Lingchuan Mansion.

Ji Xinyu will definitely not leave those food supplies, after all, there is still more than a month before the rice harvest, these grains are the only remaining rations in Futian Village, when the losses are being counted, the guards came to report that there are 4 old people in Futian Village who failed to escape from the village in time and were killed by pirates.

Ji Xinyu felt sad, the lives of the people in this world were really too fragile, so He Xingwang found the families of the four old people, and gave each family five taels of silver to buy coffins for funerals, and the families of the four old people immediately knelt together.

This battle also made Ji Xinyu more aware of the cruelty of this world, this world is not something you can be stable if you want to be stable, and the guards of the Guards Division also fully understand the changes in the way of war with the valley rifle, and with this valley rifle, you will no longer come up and fight with the enemy in close combat.

Ji Xinyu interrogated the captured pirates and learned that they had a total of more than sixty pirates this time, led by two leaders, one of whom was killed, and the other had fled, and it was unknown whether they would organize revenge.

Ji Xinyu also took advantage of the situation and Chen Yu to strengthen the training of the guards, especially emphasizing the importance of military orders and familiarity with firearms, Ji Xinyu's requirements are to achieve at least 5 seconds of reloading, and a group of five people to take turns shooting in a team to avoid repeated kills.

After watching the training of the guards, Ji Xinyu came to the glass workshop, and the escape of one leader made him feel a little pity, if he shot at a target, the other leader would definitely not be able to escape.

After thinking about it for a long time, Ji Xinyu decided to add scopes to several valley rifles to snipe at important targets, although the current valley rifles only have a range of more than 300 meters at most, but if the marksmanship is good, it is still easy to kill the opponent's important targets by hitting the vital point at more than 250 meters.

Ji Xinyu went to the porcelain workshop to find the porcelain handle Yan Kuan, and asked about the details of making the crucible kiln, the porcelain of Zhongzhou Kingdom will use different temperatures because of the needs of different porcelain, and to control these, the porcelain handle needs to accurately grasp and control the temperature in the kiln.

Qualified porcelain handles have rich experience and skills, and only need a drop of water to judge whether the temperature in the kiln has reached the temperature they want, and at the same time can control the speed of heating and cooling, and the duration of the highest temperature, which is simply a humanoid intelligent temperature controller. The porcelain head who has mastered these is naturally also a master of building a kiln, and it is very particular about where to leave the observation hole, what position to leave the feed hole, and what position to leave the air intake hole.

Ji Xinyu wanted Yan Guang to build a high-temperature crucible kiln for making glass, and the location was built in the workshop built next to the biogas digester, and Yan Kuan said specific requirements, the high-temperature crucible furnace is divided into two parts, built with cement and clay insulating refractory bricks, the upper part is the crucible room, the lower part is the combustion chamber, and there are air heating chambers on both sides of the combustion chamber.

After heating in the combustion chamber, the furnace door is closed, and then the air is continuously blown into the air heating chamber with a blower, so that the hot air in the heating chamber is pressed into the combustion chamber by cold air, and there is a flame nozzle at the junction between the combustion chamber and the crucible chamber, and the strong flame can raise the temperature in the crucible to extremely high.

After listening to Ji Xinyu's teaching, Yan Kuan also felt that these changes could indeed increase the temperature of the crucible kiln, so he and a few helpers began to build the kiln, Ji Xinyu was worried about the quality of the coal, and went to see the situation of soil coking, and asked Aiden to test the coke made by the smelting, Aiden said that the method was a little soil, and the coke was still good.

The crucible kiln took two days to build, and the crucible was also Yan Kuan's masterpiece, but Aiden took advantage of Yan Kuan's lack of attention, and still incorporated the crucible into the space for some transformation, mainly to improve heat resistance and thermal conductivity. Then Ji Xinyu began to experiment with glass, came to the warehouse to prepare quartz stone, limestone, soda ash and other materials, let people carry them to the workshop, called Yan Kuan and a few porcelain craftsmen to stay aside and teach them again, and then began to practice.

First let the two cooperate to fix the crucible and heat it to high temperature, the crucible is red and put into the quartz sand, and then add limestone and soda ash as a co-solvent, and add some borax and feldspar as auxiliary materials, and after a while, the raw materials in the crucible have begun to melt, and after it is completely melted, Ji Xinyu adds saltpeter to decolorize, the glass is green because it contains trace amounts of iron, especially the bivalent iron is green alum is green, Ji Xinyu added saltpeter to oxidize the divalent iron to trivalent iron, and the trivalent iron is relatively stable to make the glass appear colorless and transparent.

After completion, annealing can be carried out, and finally salt is added to clarify and defoam, salt is used as a clarifying agent here, and volatilization will form large bubbles when heated, and these large bubbles will bring out small bubbles during the rise, which can reduce the bubbles in the glass, so that there are no bubbles.

After cooling the glass slightly, it is poured into a molder made of wrought iron, molded and pressed down, and after a thorough cooling, a transparent glass with a handle is successfully made.

Looking at the formation of the glass, Yan Kuan next to him was already stunned, standing behind Ji Xinyu, wanting to get close but not daring to get too close.

Ji Xinyu put the glass on the table and said to him: "Look at it, how does it feel, isn't it beautiful." ”

Yan Kuan circled around the glass, he didn't dare to touch it, and now he can't believe that this thing was just made by him, and he has already stammered a little when he speaks: "Less...... Master...... Is this a heavenly thing? ”

"This is what we just made, he is called 'glass', and after a while you recommend a porcelain craftsman who has performed well, let him be in charge of building a kiln and starting a workshop, and then gather craftsmen from outside the house to produce these things." Ji Xinyu shook his head, pointed to the glass and said.
