The next day, Li Jing directly found the big housekeeper Li Zhong and borrowed a large warehouse built with bamboo poles near the riverside wharf. These warehouses, all fourteen or fifteen meters high, have the roof of Straw Hill on top, and the four walls are straw curtains, which are very simple and have been empty. Li Jing is optimistic that the place here is big enough, several acres in size, and has good lighting (in fact, it can only block the rain through the wind and light everywhere).

Then let the sword go to the town's best blacksmith Wang Laosan to find, Wang Laosan is about 1.85 meters tall, followed by the two apprentices are also about the same as him, the body is thick and strong, dark face, I heard that it is Shandong refugees, in this town has been able to live for more than 20 years, the craft has nothing to say, as soon as he entered Li Jing's middle hall, Wang Laosan hurriedly crossed his hands to salute.

"The eldest prince is looking for a villain, and I don't know what to order"

"Sit down, you're welcome, my son has a business to take care of you, Xiaomei serves tea."

Wang Laosan and the two apprentices didn't dare not sit, so they had to sit on half of their buttocks.

"Xiaolan, Xiaoju, go and bring the drawings of the young master last night" The second maid went to the study and brought the three-view scroll of Li Jing, who was busy in the middle of the night last night, with a quill pen to occupy the ink, and with a ruler to draw a movable pulley.

"Open, open. Master Wang, if you look at it, you may understand. ”

Wang Laosan stepped forward and looked at it carefully, the two apprentices were also watching from behind, and whispered and discussed in a low voice from time to time, Wang Laosan was obviously literate, and the two apprentices were also coarse in writing and ink. After a long time, I took a deep breath, and the planning of this drawing is neat, the proportion is accurate, especially the three-sided view, it is even more clear at a glance.

After reading the drawings, Wang Laosan bowed deeply and said solemnly: "Son, although Xiao Lao'er doesn't know what this moving pulley set is for, but the design of this thing is exquisite and ingenious." The drawings are shaped, and the data are all detailed. It's easy to see at a glance. ”

Li Jing hurriedly said: "Can it be made in the end?"

"There is no problem, large pieces can be cast, small pieces can be built, this specification of washing iron chains, I have ready-made goods in my shop, which are used on the dock, and this cast iron barrel, there is no problem, dare to ask what iron is used to make it."

"The pulley block is made of the best Foshan steel, and after it is done, I will give you a tempering process, and the surface needs to be strengthened to be hard, which is used for wear resistance. As for cast iron barrels to order ten, ordinary cast iron will do. Let's take a look at the pulley set first. ”

Wang Laosan calculated it and said, "There are more than a dozen men in my workshop who have enough iron, and they are working day and night, and the cast iron barrels are delivered in ten days, each fifteen taels of silver." Don't hide it from the child, this subway is not expensive, but pouring large objects with a diameter of three feet, others really don't have this ability. I dare to guarantee that there are no bubbles, no sandstone, and I usually use tung oil lard to prevent rust, and I promise that it will not be bad for fifty years. As for the wheel group, although the object is small but time-consuming and labor-intensive, it is necessary to use the best Foshan steel, not less than 50 taels per group. Half a month later, you can see if you can deliver the child. ”

Li Jing thought about it, and went out for 200 taels at once, and the silver was really not too much, so he nodded and said: "Okay, a word is a certainty, Xiaolan will give a deposit of 50 taels to Master Wang." ”

sent away Wang Laosan's master and apprentice, and asked Bai Yu to find Li Fu in the ancestral hall, Li Fu has a short figure, a pair of mung bean eyes, and looks like a round ball.

Li Fu hurriedly bowed and saluted, "I don't know what the young master commands"

"I remember that there were a lot of stone pillars left over from the construction of the ancestral hall, and they were all abandoned in the grass behind the ancestral hall."

"Indeed, there were more than a dozen, ten broken pillars three feet thick and more than one zhang long, and five large pillars four feet long and three feet thick. It's all good granite, and it's been abandoned for decades, and I don't know what the young master suddenly asked about these useless things. ”

"Don't worry about this, I'm useful, go back and find some long-term workers, and transport me to the herringbone warehouse with rolling wood, which is the warehouse on the east side of the dock that has been idle for more than ten years." Each guy gave twenty catties of rice, and went back to Xiaolan to withdraw it. ”

Li Fu usually guards the ancestral hall and has nothing to do, these stones are rebuilt and replaced by the ancestral hall, and the specifications are not suitable for quarrying, they are still goods, but they are too heavy and abandoned in the barren grass. Since the eldest young master wants it and gives him wages, why not do it, he can still have some benefits left. So he said yes.

Li Jing sent the sword to find the bricklayer and stonemason, cut a trench in the warehouse, sank the river sand, laid the stone slabs, and then built twelve stone walls, and placed the long stone pillars horizontally on the stone wall, and between the two walls there was just a three-foot diameter cast-iron barrel. The long stone pillar is used to hang the pulley block. The stonemason polished the small stone pillars according to the inner diameter of the cast-iron barrel and chiseled out grooves and perforations to wear through the huge cast-iron rings.

One meter of granite weighs three tons, and this short stone pillar weighs about ten tons.

Half a month later, Wang Laosan brought ten cast-iron buckets with his apprentices and dozens of helpers to install them on a stone seat in the middle of the stone wall. Watching Li Jing hang up the movable pulley with his own hands, pulling the iron chain without obvious effort, the stone pillar slowly rose. Almost sat on the ground with a butt. The apprentices, Lao Wu and the helpers present all grew their mouths and were almost stunned.

Li Jing looked at the stupid crowd proudly, enjoying the eyes of the crowd as if worshiping a god, and shouted to start work.

The twenty newly recruited men, under the command of Lao Wu, hurriedly packed the steamed and fried rapeseed billets with a diameter of three feet and a thickness of one foot thick wrapped in straw rope into cast iron barrels one by one, and each iron tong could be loaded into five billets.

As the stone pillar was slowly lowered again, the oil outlet under the iron pass began to flow out of the clear rapeseed oil, and the wooden barrels below began to receive barrels one by one, and after half an hour, the oil production finally stopped. Lao Wu trembled his lips and began to weigh them, his hands and feet were not good, and after a while, Lao Wu shouted, "Oh my God, the oil yield has more than doubled." ”

The problem is that people can only work in three shifts to sleep at night, but this oil press does not need to rest, only two people are enough to change shifts, and everyone else goes to deal with rapeseed billets. In the past, a processing process had to hit one day and one night, but now it only takes half an hour, the efficiency has increased by 12 times, and the manpower has been greatly reduced. Lao Wu shuddered, and this began to calculate the purchase and shipment volumes. After the group, he said with a pale face: "Young master, Chengxiang County can't sell such a large output, even Chaozhou Mansion can't digest it." Working day and night, raw materials are not a problem, and manpower is sufficient, but the output is too large.

Li Jingyun smiled lightly, "Young Master Ben doesn't plan to sell it locally, and I plan to ship it all to the north." “

Lao Wu said: "Now the north will definitely be able to sell at a good price, but the wind direction is wrong, so we have to wait until the southeast wind rises in the beginning of spring and pass with the trend." ”

Li Jing smiled: "I have my own clever plan."
