Chapter 174: Mr. Fan

Su You came to Mr. Fan's study, where Mr. Fan was packing up the manuscript.

Seeing Su You's arrival, Mr. Fan smiled and said, "Have you made friends with Yuanzhen?" ”

Su You couldn't laugh at all: "Sir, listening to your words at lunch, are you going to live here for the rest of your life?" ”

Mr. Fan said: "Mingrun doesn't have to be like this, there is nothing bad here, there are four undefeated flowers in the second forest department, eight sections of evergreen grass, although Wenhua is rough and straight, but people are enthusiastic." In my opinion, it's much better than the intrigue among the big clans. ”

Su You asked, "Mr. is from a big family, right?" ”

Mr. Fan nodded: "Sort of, it's just a concubine, and he hasn't gained fame in his thirties." The family was not virtuous, and I was forced to fry everywhere, so I was angry for a while and threw myself into the wilderness. ”

Su You arched his hand and said: "If Mr. doesn't dislike it, Meishan can live." ”

Mr. Fan shook his head and said, "That's it, I'll stay in the Erlin Department, and the big ghost master can rest assured." ”

Su You still needs to be persuaded again, but Mr. Fan raised his hand to stop: "My life's career is here, how can I waste it halfway?" Mingrun, you don't need to persuade me anymore, I'm very good here, really good. ”

After speaking, he took out two bookcases: "This is my notebook experience in the past 20 years, and I have collected all kinds of roads, customs, tribes, and the evolution of the situation in the past hundred years in Southwest Yi and Dali. ”

"The defeat of Haoshuichuan is really embarrassing. There is an important reason, that is, because the geography is unknown, and the enemy is not clear. ”

"The Yunnan map collected by Wang Quanbin in the Shu Palace is a hundred years old. If something happens in the southwest, I'm afraid it will be unbearable to use again. You take these away. ”

Su You bowed down and said: "Mr. is painstaking, and the kid sincerely admires it." ”

Mr. Fan said: "I still came to Meishan to understand that the word mutual benefit is the way to the southwest, which is still inspired by you." The dumb riddle I played with the general at noon, can you figure it out? ”

Su You asked, "Is it what Brother Holie is going to do next?" ”

Mr. Fan nodded: "Yes, let's talk about it." ”

Su You said: "The business road has been opened, and the next step is naturally to consolidate, what I want Brother Holie to do is to clear out the bandits on the business road." ”

Mr. Fan smiled and said, "That's really smart. Tell me, if it were you, how would you behave? ”

Su You said: "I don't know much about the forces around the Second Forest Ministry, I think that with Mr. Fan in charge, it is already planned and then moved, plus the soldiers of the Second Forest Department are brave, there should be no problem with force." I just want to ask, if it is cleared, what about the route of the march? ”

Mr. Fan said: "The Second Forest Department is in the north, so naturally it is advancing from north to south, step by step, until Jianchang Mansion. Such grain and grass, advance and retreat, are abundant. ”

Su You arched his hand and said: "There is too little information to determine, but from what I know, sir, I suggest the opposite." ”

Mr. Fan: "Oh? "How is it the opposite?" ”

Su You said: "I'm afraid that Mr. has been thinking about this issue for a long time, so he has fallen into a fixed situation. In fact, we came from Dali this time and got acquainted with Gao Xiangye and Xiao Yanei, and the situation should change again. ”

"If we go from north to south, there will be a problem - the bandits may be driven into Dali by us. When we return to the army, they will come back and resurrect, how can this problem be solved? Could it be that the Second Forest Department still dares to drive troops into Dali? ”

"Since ancient times, it is not uncommon for officials and bandits to collude and raise self-respect, and the bandits on the way are related to the defenders of Jianchang Mansion.

Mr. Fan couldn't help but start tapping his fingers on the tabletop and thinking.

Su You continued: "Now that Xiao Gao Xianggong has entered the Song Dynasty, my suggestion is to stay still and endure for a few more months. ”

"Then we will openly explain our plan to Xiao Gaoxiang, let him go to Jianchang Mansion, and lead the army to attack from the south to the north, at least to prevent it from the end."

"Xiao Gao Xianggong has just made meritorious contributions in literary affairs, and then he can make meritorious contributions in military affairs, I don't think there is anything unhappy."

"In this way, no matter whether the defenders of Jianchang Mansion colluded with the bandits or not, the bandits were ready to be attacked."

"If there is no collusion, they will be under the command of Xiao Gao Xianggong; If there is collusion, then you can only sacrifice your pawn to protect the car. ”

"In this way, the two armies will be flanked, and the bandits will have no way to escape, and this is a plan to cut the grass and eradicate the roots."

"After that, we will repair the relationship with Jianchang Mansion and share some of the dividends on the business road. In this way, we took advantage, increased our combat power, and cleared up the trade routes; Jianchang Mansion shared the benefits and obtained military exploits; Xiao Gao Xianggong continued to increase his prestige in China; Wouldn't it be nice to each to have what he wanted? ”

Mr. Fan said: "It's just that the circle is a little big. ”

Su You said with a smile: "Although the trouble is a little troublesome, it is better to solve it once and for all, and it is difficult to make changes." ”

"If Mr. agrees to this policy, then when the minister returns from the envoy and passes through Sichuan, I will persuade him!"

Mr. Fan slapped his thigh: "Okay!" The lion fights the rabbit, and you should do your best, you can get more strength to help, then it will naturally be more secure! ”

After setting a strategy, he moved to internal affairs again, and talked about the next thing to help the Second Forest Department.

Before walking out of the door of the study, Su You turned around again: "Sir, can you tell Su You about your hometown?" Or your real name? People like you should not be lost in history and leave no name. ”

Mr. Fan smiled slightly: "Mingrun, your idea is utilitarian." ”

Su You had no choice but to bow deeply and turn to leave.

In the early morning of the next day, Ah Ho Lie led Shi Tong to explore the copper and iron mines.

The wind in the Anning River Valley is extremely strong, and Su You only remembered that this is a windy area in Sichuan after entering the valley, so there is no need to use hydraulic power, revise the drawings, draw windmills on the boat, and make models.

China has had a vertical water mill a long time ago, and the wind mill is actually a vertical water mill that has been slightly modified.

After a year of recollection and experimental calculations, Su You has made the formula of the involute helix on the basis of the equidistant helix.

With this, the analytical formula of the involute gear can be deduced, and the involute tooth profile meshing transmission can be theoretically realized in Dasong.

This kind of gear has three major characteristics: the transmission ratio is constant; The change of center distance does not affect the transmission ratio; A meshing line is a straight line that passes through a node.

Don't underestimate these three points, in mechanical motion, the first point can maintain a constant speed, the second point accommodates errors, and the third point reduces friction and vibration.

Today's Great Song Dynasty, he is the only one who can understand the formula, and the children in the land temple are still playing circles and straight lines, just getting in touch with trigonometric functions, and are just establishing trigonometric function tables.

However, Su You was very confident in the gang of Heavenly Supervisors of the Great Song Dynasty, they could make a hydraulic clock, calculate the radius of the celestial sphere, calculate the theoretical distance from the earth to the celestial body, and find errors with actual observations.

It's just that they don't realize that this error is actually caused by the difference between theoretical calculations and actual observations.

The theoretical calculation is to treat the Earth as a point, the center of the earth, and then calculate the distance to the stars.

The actual observation is the distance from the ground to the star.

In other words, these demons have actually calculated the radius of the earth! This error is actually the radius of the earth!

Therefore, Su You believed that as long as a small hole was poked into the curtain, the clever Song Dynasty people would tear this small hole bigger and bigger, and finally completely expose the light, and understand that these may be faster than he expected.

Mathematics is the basis of materialist dialectical thinking and the way of proof, and the problem of the Great Song Dynasty is that there are talents, and they are still very refined, but there are too few.

His task is to simplify the way of expression, facilitate understanding and dissemination, expand the crowd of this gang, and then people may not need him.

Only after the formation of the group can there be the power to correct deviations.

As for whether it has to be done by yourself, it really doesn't matter.

Compared with the ideal gear, the gear used in the windmill of the second forest department is called simple and rough, and it is even rougher than that of the laboratory in Kelongli.

This is still the kind on the guide car in the Western Zhou Dynasty, that is, two large round wheels, with a good angle of holes and nails into the wooden stick, so that the wooden stick and the wooden stick bite and push each other.

The craftsmen of the second forest department nodded happily, we can see that we can do it!

The only thing that can be called more advanced is that the transmission shaft uses ceramic roller bearings brought by Meishan.

The windmill is still four-bladed, and the canvas can be rolled to adjust the size of the wind surface and adjust the speed according to the wind.

Add a stone mill, a wind row, or a lever hammer to get a mill, a large blower, and a forging machine.

It can be used for grain processing, ore crushing, smelting, and forging.

Of course, Su You couldn't personally participate in the construction, so he threw the drawings and disassembleable models to Li to tie up, pulled Ah Ho Yuanzhen by himself, and rode a horse to the mine.
