On the banks of the Cheonggye River.

Standing tall in the Jiangning warehouse, it was in full swing at this time, and the employees were busy. Some of them are carrying the jars, while others are moving the jars to the warehouse next to them for temporary storage.

In the brewery, a huge cast-iron pot is steaming, and on top of it is a double-layered cast-iron pot, in which cold water is fed into the middle, forming a cooling device, and the cold water is brought in by a bamboo pipe from a large wooden barrel on a high platform, and then flows into the waste pond, and finally discharges into the Qingxi River.

Accompanied by Xu Xiaoying, Wu Qing watched his design become a real thing, and a sense of accomplishment arose spontaneously in his heart. He strolled among the hired laborers, lingered among the various fermentation pools, and watched the crystal clear liquid slowly flow into the wine vat at the end, the aroma of wine was fragrant, and Wu Qing smiled sincerely.

"I've seen Childe!"

"Childe is well!"

The greetings from the hired workers made Wu Qing feel that he was recognized, although the status of merchants in this era was low, but they could eat a mouthful of food, which was also a good deed, not to mention, the new model of large-scale employment was much fresher than that of slaves and servants. Wu Qing hopes that in the future, all workshops will use this employment model, and they must sign a pledge for at least five years, and re-enter into an employment relationship every five years.

For this kind of employment document that is not a deed of sale, the county commander Lu Zhaolin specially discussed it with Wu Qing, and soon Lu Zhaoling was persuaded by Wu Qing, so that there is such a prosperous scene today.

Wu Qing saw that there were many hired workers carrying water, and he asked strangely, "Sakura-chan, what are these people carrying water for?" ”

Xu Xiaoying thought for a while and said, "The water in the big bucket at the height was used up too quickly, so I had to assign ten people to carry the water. ”

Wu Qing frowned, this is obviously the reason why there is no power equipment, if there is a pump and electricity, it will directly pump water from the river for condensation. Moreover, there is no temperature control, so the cooling water is also opened to the maximum, not to mention waste, but the quality of the brewed wine is good and bad.

Wu Qing sighed, it is not generally difficult to engage in industry in Datang, even this light industry is difficult to start. Looking at the sweaty employees who carried the water, Wu Qing's mind suddenly flashed.

Wasn't there a physicist named Archimedes in ancient Greece? In order to be able to use the Nile River to irrigate farmland, he invented the manual auger pump, which later became known as the Archimedes spiral principle.

Wu Qingke knew the principle of Archimedes spiral very well, and he didn't go to see the paper workshop and sugar workshop at the moment, so he returned to the Wu Mansion.

Entering the house, he went into the physical laboratory alone, there were ready-made tools and wood in the real room, he first hollowed out a bamboo tube, and then put a small wooden pole on the eye, and then sawed the wood into pieces, carved into a semicircle piece by piece, and then needed to carefully inlay these wood chips on the original wooden pole, and finally put the wooden pole into the bamboo tube, fixed at both ends of the bamboo tube, and made a simple Archimedes spiral pump, of course, Wu Qing brazenly prepared to be crowned "Wuqing spiral pump", Although the Tang Dynasty had frequent exchanges with the countries of the Western Regions, it was far from reaching the spark of cultural collision.

It took three days to do it, and three days later, Wu Qing came to Jiangnan Boat Line with a simple spiral pump.

Behind the Jiangnan Chuanxing Walled Building, there is a mansion that covers a vast area, which is the mansion arranged by Dong Xiaowan for the descendants of the public loser, Yuwen Debate Machine and Yuwen Yiyang, father and son, according to Wuqing's will.

At this time, the father and son were working on a ship with a deep draft, and were making a series of improvements to the hull based on the experience of their predecessors.

"Uncle Yuwen, Brother Yuwen!"

A hearty voice suddenly came from behind him, Yuwen father and son, who were busy, were startled, Erhu put down the work in his hand, turned around and saw that it was Wu Qing, and the two hurriedly bowed: "I don't know if the son is coming, I hope to forgive my sins!" ”

Wu Qing smiled and said: "I'm really happy to see that you were able to design such a ship in such a short period of time, if I guessed correctly, this should be a sea ship with a deep draft of tens of thousands of stones!" ”

Yuwen father and son were stunned, that's right, they were designed tens of thousands of stone sea ships, ready to surprise Wuqing after January, but they didn't expect people to see it, Yuwen father and son instantly showed a worried look on their faces, and then arched their hands and said: "Childe is really smart, my father and son are not as good!" ”

Wu Qing was speechless, and then said: "Uncle and Brother Yuwen's design, I have only designed it before, so I know something about sea ships, so I recognized it when I saw this model." ”

When the two heard Wu Qing's explanation, they would also be suspicious, who let Wu Qing have the halo of "prodigy" on his head.

Yuwen still saw that Wu Qing was not here for the sea, so he asked: "Gongzi came here today, I think there must be some orders, and I also ask Gongzi to show me, my father and son will never regret it!" ”

Wu Qing took out the model of the spiral pumping machine from the cloth bag and said, "This is my recent invention zào, you can take a look, what can you find?" ”

Yuwen debated the light in his eyes, and then received it in his hand, to be honest, he had heard of the legend of Wuqing for a long time, and he didn't realize until today that those rumors were really true. Although he didn't know what this combination of bamboo tube and wooden pole could do, it must have been useful.

Wu Qing smiled: "Uncle, you can put it in the water and take a look." ”

Yuwen Yiyang took the bamboo tube, then put it in the barrel, and tried to turn the wooden pole, and suddenly a stream of water came out from the top. Yuwen Yiyang didn't see anything. But how could Yuwen Debater, a child of the Mo family, not understand?

He excitedly snatched the bamboo tube, then spun the wooden pole and saw a stream of water be pumped out of the barrel. Yuwen debated his hands tremblingly, and said: "Gongzi is really a god, and he can use the technique of the mechanism to transport water from the place to the height, which is much more clever than Ma Jun's keel waterwheel." ”

Wu Qing's face couldn't help but blush, fortunately, he had already stolen countless achievements of the predecessors, and he had cultivated thick skin and thick flesh, so after a while, he said seriously: "I want to build a water tower in the winery, just use this pumping mechanism, I hope that Uncle and Brother Yuwen will improve it, and then install it on the water tower." ”

At this moment, the arrogant Yuwen Yiyang also lowered his arrogant head, the wisdom that the master of the organ Ma Jun can't compare, can he compare?

Yuwen said cautiously: "Please rest assured, son, in just a few days, my father and son will definitely have results!" ”

Wu Qing smiled with satisfaction, and then walked out of the house, but saw Dong Xiaowan coming at a gallop, Wu Qing knew that he couldn't dodge, so he stopped, and when Dong Xiaowan approached, Dong Xiaowan glanced at Wu Qing, and then walked directly into the house, and cooled Wu Qing aside, Wu Qing was stunned, and felt that this girl was not here to find herself. I felt strange in my heart, but I heard footsteps behind me. Then he felt a soft body close to his back, and his hands wrapped around his waist.

I only heard Dong Xiaowan say resentfully: "Stinky boy, am I so scared of you, even if I can't marry you, I will be content with you like this!" ”
