"The impact of the waterfall is already very powerful, and then multiply it with gears, uncle, this hydraulic wire drawing machine is the reason?"

Sun Hedou was holding a notebook, holding a quill in his hand, and drawing something on it - he had become more and more accustomed to using the more simple and convenient quill pen.

"Good! Finally, the water wheel is loaded...... Team Leader Wang, release the clutch first, and then close it after installing the water wheel! Chu Fan raised his head and instructed Wang Denghai to install the water wheel with a diameter of 6 meters, composed of six spokes and a circle of wood pulp leaves, on the main wooden tower with a height of 3 meters, and then turned around and answered Sun Hedou's question, "That's right, with gears, the size and direction of the force can be controlled at will." ”

"According to Uncle Shi's words, the size of the force of gear transmission is determined by the proportion of the diameter of the gear," Sun Hedou asked as he looked at the huge water wheel, "However, there is something wrong with Hedou." ”

Chu Fan looked at him and asked, "What's wrong?" ”

Sun Hedou pointed to the last gear with a diameter of 2 meters and asked, "The diameter of the water wheel is 6 meters, and the diameter of this wheel is only 2 meters, isn't it that the hydraulic power has not been amplified, but has been reduced by 3 times?" ”

"That's not the case," Chu Fan shook his head, pointing to the bronze gear that was coaxial with the water wheel, "The power of the water wheel, the size remains the same, first transmitted to this wheel, this wheel has a diameter of 10 centimeters......" Then he pointed to the big gear with a diameter of 2 meters that was bitten with it, "Then from the small wheel to the big wheel, Brother Gongzai calculated, how about the increase or decrease of its force?" ”

Sun Hedou calculated, "So the water power has increased by 20 times? ”

Chu Fan smiled, "Exactly...... You see, there is still a small wheel with a diameter of 10 centimeters on the same axis as this big wheel, and the hydraulic power that has increased by 20 times is also transmitted to this wheel at the same time...... If the large wheel connected to it is also 2 meters, how does its force increase or decrease? ”

Sun Hedou suddenly realized, "...... I see. As far as I know, the water power increased by 400 times in the end! …… Uncle Shi's thinking is very ingenious! And the fighting heart is convinced! ”

Chu Fan smiled and turned to Wang Denghaidao, who had already installed the water wheel, "Team Leader Wang, you can close the clutch!" ”

With the pull of the bronze wrench, the gear set creaked. Hearing the tooth-sore sound of metal rubbing, Chu Fan asked Wang Denghai to release the clutch again, and asked the craftsman on the ground, "Is the vegetable oil you prepared ready?" ”

His own craftsman brought a small can of vegetable oil in response, Chu Fan dipped the brush in the oil, and carefully brushed the pinion, then turned his head and said to the stunned Wang Denghai, "Team Leader Wang, you will have to brush it every day in the future." in order to maintain the lubrication of the gear set. ”

Wang Denghai said with a look of embarrassment, "Childe...... If you brush it like this, this can of vegetable oil is not enough even twice...... This vegetable oil is expensive! "After each group is responsible for its own profits and losses, all the materials received will be priced, and he can't ignore the cost.

"Huh~~" Chu Fan glared at him after snorting coldly, pointed to the large and small gear sets, and said, "These gears were cast by yourself, and you know better than me how much silver it spent...... If the lubrication is insufficient. It won't be long before it will have to be scrapped and recast...... Gear is expensive or vegetable oil is expensive, you can measure it yourself! ”

Wang Denghai was stunned by him, and secretly stuck out his tongue - the gears were all cast in bronze. A set of gears costs enough money to buy hundreds or thousands of cans of vegetable oil!

Thinking of this, he hurriedly took the brush in Chu Fan's hand, and oiled the gear set tooth by tooth; Chu Fan's words played a huge role, Wang Denghai turned to the other extreme, and when the entire gear set was brushed, there was not much left of the can of vegetable oil that could have been used for two days.

After oiling. The tooth-sore metal friction sound was finally much quieter, and after Chu Fan watched and finished pulling a steel rod, he told Wang Denghai to do the same, and build the remaining two hydraulic wire drawing machines as soon as possible, and then take the traffic boat back to Niudao.

I just got off the boat when I arrived at the pier. An unexpected person appeared in front of Chu Fan.

――――――――――――――――――――――――――――――――――――――――――――――――――――――――――

In Jeju City, in the backyard of "Choi Kee Bean Soup Cold Noodles", in a secret room separated from the West Wing.

In the dim light of fish oil candles, Ling Ming, Chu Meng, and a North Korean who had been captured by Ling Ming on Niu Island were touching their heads, rummaging through a large pile of paper, even though it was already cold late autumn, and they were both busy sweating profusely.

"Master, look at this!" Chu Meng found a piece of paper that looked like an official proclamation from the writing paper and handed it to Ling Ming, "I understand the words of the shepherd." ”

Ling Ming took it and looked at it, nodded and said, "Brother Meng is good, this is a proclamation issued by Cui Mu Envoy to the various lieutenants, asking them to repair the docks of Jeju City...... There is nothing difficult in the world, but I am afraid of people with hearts, as long as you are willing to learn, are you afraid that you will not be able to learn Korean characters? …… With this 'shepherd', don't you recognize more than a dozen Korean words? ”

Needless to say, "Choi Kee Bean Soup Cold Noodles" is the stronghold of the Special Intelligence Division in Jeju City, and Ling Ming used the identity of the shopkeeper as a cover-up to personally improve the organization and training of this stronghold here.

And since Chu Meng saw the magic of the former Jinyi Wei Xiaoqi on Chengshan Island last time, he had to worship Ling Ming as his teacher, and after the latter asked Chu Fan and got permission, he absorbed Chu Meng into the Special Intelligence Division.

Counting Chu Meng, there are now 37 people in the Special Intelligence Division, most of them are Ling Ming's old subordinates when he was in Niudao, and the rest are all North Koreans who Ling Ming developed when he was lurking in Jingyi County - for example, the Honggu who Ling Ming fished out of the brothel in Jingyi County and is now disguising herself as the proprietress of the boss.

Except for the eight people in this stronghold in Jeju City, the rest of Ling Mingquan stayed in Jingyi County, and under the leadership of an old subordinate named Tang Huairen of Ling Ming, he used various occupations and identities to help the Fuliao army take control of Jingyi County while searching for information - of course, several people had already infiltrated Dajing County in the southwest corner of Jeju Island.

At the same time, Ling Ming also identified 12 young Liao people who he thought had potential in the third batch of displaced people, and handed them over to Tang Huairen for training in order to prepare for the next expansion of the Special Intelligence Division.

And Cui Ji Noodle Restaurant, in just about ten days from its opening, has made progress that Ling Ming did not expect.

"It is almost certain that most of the proposals to crusade against our Liao army have been approved by the Korean royal court, and the next step should be to determine the scale of the troops, as well as the competition for the position of this leading general by all forces in Korea." Looking at the thick stack of various documents and even private messages in front of him, Ling Ming muttered - these raw information will be handed over to Chu Fan along with Ling Ming's report.

Ling Ming knew very well that the reason why such rapid progress could be made was inseparable from Chu Fan's suggestion to Ling Ming on the day the establishment of the Special Intelligence Department -- to engage in intelligence, it was not necessary to disguise himself and infiltrate the herdsman's yamen to spy on him, but on the contrary, a large number of clues could often be obtained from the information obtained through many open channels.

"More than ninety percent of reliable information is often hidden in something at your fingertips!" Chu Fan's original words completely subverted Ling Ming's previous perception of intelligence work, and the example Chu Fan gave later made Ling Ming have a clear vein in his heart - collecting the other party's words and paper that were discarded like garbage was one of the most effective methods.

Ling Ming was lucky, and on the day of the opening, he became acquainted with the old man who was collecting paper along the street, and with his means, he soon found the paper burning shrine in Jeju - a place dedicated to burning paper with words on it - and then waited for the rabbit to wipe out almost all the scavengers in Jeju City; With a little lure, Jeju City's daily calligraphy and paper have a new place to go - Choi Kee Noodle Restaurant.

After only ten or so days of collection, Ling Ming had already found a large number of clues, and thus came to the above conclusion-you know, if he adopted the traditional method of Jinyiwei, he didn't expect to make such progress at all in three or two months!

Even engaging in intelligence can come up with such a strange trick, Childe is really a god! What else in the world he wouldn't?

When writing a report to Chu Fan, this sentence kept rolling in Ling Ming's heart. (To be continued.) )

PS: I'm really sorry, it's been a busy day, and it took two hours to go back to the hotel in the afternoon to rush out of this chapter, don't be surprised
