After the production of the barrel of the ordinary firebolt is completed, it is generally tested by double the gunpowder, while Ji Xinyu stipulates that the barrel of the Gu-style rifle needs to be tested by three times the gunpowder before it can be fused with the bolt after the barrel is made, so as to avoid the risk of exploding the chamber as much as possible.

Niu Gu's steel experimental team has been supplemented by personnel, plus the use of several machine tools, the efficiency is very high, Niu Gu began to make the bolt machine while observing the needs of the craftsmen next to him to study the new machine tool under the encouragement of Ji Xinyu.

With his own experience in making milling machines, Niu Gu also paid attention to the needs of other craftsmen, and then made the standard mold required for the barrel, and then used the lever principle to make a primitive human forging machine with bearing gears, the forging hammer fixed above the forging machine has a convex mold, and the concave mold below can also quickly create a semi-formed steel pipe blank, and finally the blacksmith takes a concave hammer to polish the steel pipe flat, so as to improve the efficiency of producing steel pipe blank again.

Along the completed cement road all the way into the workshop area, Ji Xinyu could already see the shadow of the factory in his previous life, which made him feel emotional.

Now not only has the cement road been completed, but the Lifang residential area planned by Ji Xinyu has also been led by Li Hongzhuang, the leader of the stonemasons, to build a series of double-storey small buildings. According to the drawings given by Ji Xinyu, these buildings combine the style of modern villas and ancient courtyard houses. The villa has two floors, each floor is 6 meters wide, the two rooms are 4 meters wide and 6 meters long, with a courtyard in front, one side of the courtyard is the kitchen and utility room, the other side is a closed toilet and bathroom, and the yard can also be planted with some flowers and plants.

These houses were used to house the guards brought by Lingchuan Mansion from Bashu and the displaced people received later, and they were not charged for the time being, and they were planned to be charged after all the subsequent construction was completed.

Ji Xinyu's own mansion was also under construction under He Xingwang's arrangement, and Ji Xinyu didn't ask. However, just from the area of the foundation, it occupies more than a dozen acres of land, which makes Ji Xinyu feel that it is a waste, so he also specially looked for He Xingwang, and He Xingwang's answer was: "The mansion of the prince cannot be like an ordinary house, and it is not in accordance with the rules." Ji Xinyu can only let him go.

In the city of Qiongzhou, in the early morning of the southern city, the square is extraordinarily quiet, here is the poorest family in the whole city of Qiongzhou, they are all tenants who farm for the gentry and rich families in the city, the land is not far from the south of the city, and the annual tax and silver need to be paid less than the farmers outside the city.

At this time, a few women washing clothes were gathering at the well at the intersection of the village, chatting with each other about their parents' shortcomings. A young woman with a wooden basin and a small maza in the inner street of the neighborhood came out, and greeted the others with a smile and a smile.

"Sister-in-law Xue, Sister-in-law Li, Sister-in-law Liu, you are also here."

The three people who were called looked up and saw the woman who came over and also greeted: "It turned out to be the lady of the Shen family, you also came to wash clothes." ”

"Yes, yesterday my father-in-law brought me a piece of soap sold by the Xue family firm, I came to try it today, my father-in-law saw that many people in the city have bought it before he was willing to buy it, according to the people in the firm, it can wash dirty things, and it is better than soap." The woman who was called the lady of the Shen family said.

"yes, let's try it, we'll see it too." Sister-in-law Li hurriedly came up together.

The lady of the Shen family didn't care, she first fetched a bucket of water in the well and poured it into her own wooden basin, took out a small horse and sat next to the stone, took out a piece of clothes that looked very dirty in the basin and put it on the stone, and said with a little embarrassment: "My father-in-law just doesn't know how to be clean, and he fell when he went to work outside the city yesterday, and he was covered in mud." ”

Everyone laughed and said that everyone was the same.

The lady of the Shen family took out a piece of pale yellow soap, wiped it evenly on the clothes, and rubbed it for a while, and immediately there was a lot of foam, and put the well-rubbed clothes into the water and floated for a while.

"Really clean! It's so easy to wash ......, even the most difficult collar is so clean! It's amazing. ”

"It's really better than soap! You don't even need a laundry stick! ”

Several women surrounded the Shen family lady, and asked while looking through the clothes, "This 'soap' is sold by the Xue family's firm?" How much does it cost? It's definitely more expensive than soaphorn cream. Several other women also looked at the Shen family lady with anticipation.

"It was sold by the Xue family firm, and my father-in-law said that it only cost 30 Wen, and now it seems that he will not lie to me, this soap will not be so cheap." The lady of the Shen family also looked at the clothes blankly and said.

"Shen Xianggong is an honest man, he shouldn't be able to deceive people, it's only 30 yuan? Then why can we all afford it, I will go to see it tomorrow, and I will buy one and come back to wash clothes," Sister-in-law Li said happily.

"yes, I'll see it tomorrow," echoed the other women.

"I heard that this soap can also wash the body and hair, and it can also be washed very cleanly, but I haven't tried it, so I don't know how effective it is." The lady of the Shen family said honestly with a red face.

"Since the laundry is so clean, there shouldn't be a mistake, it seems that I have to buy a few more yuan, I'll try it when I go home, it's only 30 yuan, it's really worth it." Several women spoke one after another.

After nearly a month of publicity and sales of Xuejia Commercial Bank, the sales of soap have been rising, and there was a long queue at the door within a few days of the sale, and then every day after that, the price of soap is only 30 Wen, and this month's 30,000 pieces of soap have been sold out, and Xue Rui, who originally planned to sell 10,000 pieces to Leizhou, had to give up this idea.

"Quickly bring the silver to Steward He, the Lingchuan Mansion he said is opposite Rulin Village to the north of Jiangdong, and the order volume of soap should be increased to at least 80,000 to 100,000 yuan per month." Xue Rui saw that the soap was about to be sold out, so he had to arrange for the shopkeeper to go to buy it in person.

The soap of the Xue family firm only attracted the attention of several other peers, and they inquired about the source of the soap. Xue Rui is naturally a smart person, and immediately let out the wind and only said that it was a new object from Jiangnan, and this statement did not arouse too many people's suspicions, after all, there are indeed many good things in Jiangnan, and the total import and export volume of the Xue family every month is very large, and it is still difficult to know the source of soap.

Ji Xinyu heard that Steward He reported that Xue Rui had brought a large amount of lard, and he also needed to increase the supply to 80,000 pieces per month, so he immediately arranged porcelain handles and blacksmiths, and installed two production lines on both sides of the original soap workshop, and replaced the original wooden rollers with iron rollers and added bearings, making the push and pull on the production line more labor-saving.

In addition, Niu Gu also used gears and bearings to make a fixed foot pedal and hand-cranked bellows, which improved the speed of drying and air-drying soap, greatly improved the efficiency of soap production, and the output of soap also changed from five pots a day to eight pots a day for each production line, plus the addition of two production lines, the daily production capacity increased from 1,500 to 4,800 pieces, and the production capacity of more than 140,000 pieces per month was more than 140,000 pieces, and it was completely okay to distribute 8-100,000 pieces to Xuejia Commercial Bank.

The bellows are something that has been around for a long time, but they were originally made of wood, and Ushitani uses bearings and steel to make the bellows more powerful and concentrated, and they don't dare to get too close to the fire like wooden bellows when pumping hot air.

He Xingwang did not disappoint the shopkeeper of the Xue family firm, and directly asked the shopkeeper to take away the 30,000 pieces of soap in stock, as for the monthly supply of 80,000 pieces, it is still necessary to ask Ji Xinyu, and the result remains to be discussed. The shopkeeper of the Xue family still paid very happily, but the problem came again, it was really impossible for their carriage to transport the 30,000 pieces of soap, a piece of soap was almost 200 grams, and 30,000 pieces was 12,000 catties.

Ji Xinyu asked people to pull two four-wheeled freight carriages over, each carriage loaded with 5,000 yuan, equivalent to 2,000 catties, and the same two horses pulled it, and left easily.

The center of gravity of the two-wheeled carriage is basically on the horse, and the body is uneven, the axle is laborious and the body is heavy, and it is normal to not be able to carry much goods. The center of gravity of the four-wheeled carriage is on the body itself, and the bearings reduce the friction of the axle, so it is naturally much easier to pull the horse.

Looking at the surprised shopkeeper of the Xue family, Steward He just smiled and asked Wang Fan, who was in charge of leading the team to deliver the goods, to run a few more times, and bring back more lard collected by the Xue family firm by the way.
