The autumn rain in the south of the Yangtze River is not inferior to the plum rainy season, a rain has been flowing intermittently for half a month, the humidity is quite heavy and cold to the bone, and there is no meaning of stopping.

But even on such a rainy day, there is still no desertion on the wharf of Huating Town, and it is in full swing everywhere. Cargo ships kept entering and leaving the port, and the special goods of the inland state capitals arrived one by one, and then were unloaded to the shore by the device installed with iron booms installed at the wharf, and the porters drove the wagons to transport the goods to the warehouses designated by the merchants for storage.

There is an entry and an exit, and this side is busy unloading, but other ships are busy loading. Either the wood, rice, spices and other goods that arrived from the South Seas were loaded onto ships and transported along the waterways and canals to Guanzhong, or the cargo ships of Hu merchants loaded with a boatload of silk or porcelain sailed down the Yangtze River and transported across the ocean to the foreign land of Fanbang.

Busy and thriving.

Fang Jun, Kong Yingda, and Yu Ming, the old man, each holding an oil-paper umbrella, walked on the cement road of the wharf.

Kong Yingda pointed to the iron gantry cranes by the river and exclaimed: "This thing is extremely reasonable, and it is really ingenious to be able to easily load, unload and move hundreds of kilograms of goods on the ship with the power of one person." ”

Fang Jun smiled: "Why, don't you always scold this for being a strange trick and a thing that can't be put on the table?" ”

Since ancient times, craftsmen have been everywhere for the pleasure, in the eyes of reading, all people only need to know the way of the sages in the four books and five classics, so that the world has no quarrel and no fighting, and will be the same as the world.

The best life is to plough and read for pleasure, go to the ground to grow food to feed one's stomach, and then read the books of the saints, this is the most perfect world.

Craftsmen are the most useless people, as long as people can eat white rice and understand the way of the saints, what is the use of making so many pleasures?

Kong Yingda snorted and glared at Fang Jun: "Is it true that the old man is as ignorant as those rotten Confucians?" ”

The old man Yu Ming was thoughtful, looked at the gantry crane and asked, "Boy, why can there be such a huge difference between the positions of the fulcrum of this iron beam?" The more force is required to lift the cargo, and the closer the fulcrum is to the cargo, the less force is required...... The old man has been thinking hard day and night lately, but he can't figure it out, why did the kid teach me? ”

The old man is a mad scientist, and like his grandson Yu Minglei, when he encounters such a problem that he does not understand, he has to figure out what is going on, otherwise he will not want to toss and turn and sleep.

Since the gantry crane was erected on the dock, the old man has become very interested in it.

He knew the phenomenon of leverage, but he had never cared about it before. Since seeing this gantry crane, he began to ponder the truth. In his opinion, this must be the most incredible truth between heaven and earth, and as long as he understands the principle, it will definitely be of great benefit to get a glimpse of the supreme heavenly dao......

Fang Jun smiled bitterly.

How can this be explained?

The law of leverage was there, and he had told the scientific madman countless times. But if the old man had to get to the bottom of why this phenomenon occurred, it would involve profound mechanical problems, and even the way the atoms move......

Well, anyway, the scientific principles of this era that the old man Yu Ming grasped cannot be explained no matter what.

The old man was still just asking about the principle, and Yu Minglei was even crazier.

Fang Jun said to Yu Minglei that hundreds of years ago, there was an old man in the West who said a sentence: Give me a fulcrum in the universe, and I can pry up the earth......

However, Yu Minglei went crazy.

First of all, Fang Jun has said many times that the ground under his feet is likely to be a round ball, which Yu Minglei can't understand and even can't accept, but it can be witnessed. He can sail away by boat and keep going in one direction according to what Fang Jun said, if he can return to the original point, then the earth under his feet is a ball, and vice versa.

But even if the earth under your feet is round, how big does it have to be?

How is it possible for a man to lift this earth with a stick?

So Fang Jun asked him to do an experiment.

The manufacturing bureau recently trial-produced a super artillery with a weight of 2,000 catties, Fang Jun prepared a hard wooden stick, put a rootstock at the bottom of the artillery, and then asked a craftsman's child to pry the cannon with both hands......

Since a child can afford a 2,000-pound cannon, then a stick ten times as long can naturally pry 20,000 catties of things, so can an innumerably long lever pry up countless times the weight of things, including the earth under your feet?

Yu Minglei's worldview collapsed instantly......

It's a mystical experience, like "there's something beyond the universe," a phenomenon that common sense can't explain or understand.

Fang Jun expressed regret for Yu Minglei's madness, this child can only slowly extricate himself from the nest and accept the reality that there are too many things in this world that our cognition cannot explain, and no one can help him.

Kong Yingda is just curious about these things, and he doesn't really care about this anymore.

The smoke and rain on the Wusong River, the hills on the opposite bank are faint, like a tiger standing on the dragon plate.

The old master sighed and said: "There is news in the capital, saying that His Majesty intends to relocate the Shui Shi Academy to Chang'an, and it is not allowed to be set up in Huating Town. ”

Fang Jun was shocked in his heart, and said in a lost voice: "Really? ”

Kong Yingda glanced at him and was speechless.

In terms of mastery of the news of the DPRK and China, Fang Jun is naturally impossible to compare with Kong Yingda, who has gone through three dynasties. Although the old master is old and his influence has greatly decreased, his disciples and grandchildren are all over the court, and it is naturally extremely easy to listen to some news.

Fang Jun was silent.

In fact, this has always been something he was worried about, but he thought that such a situation would only occur after the establishment of the Water Master Academy and when its influence became more and more influential.

His Majesty Li Er is not at ease......

According to Fang Jun's assumption, the Sailor Academy is almost equivalent to the Sailor Military Academy of the Tang Dynasty, and all the Sailor officers will come from here in the future. The person in charge of this school must have unparalleled influence among these naval officers, which is a great threat to every emperor.

It's not that His Majesty Li Er can't trust Fang Jun, but that he can't trust anyone......

Fang Jun said disappointedly: "Are you going to cancel it?" ”

Under the auspices of Yu Mingjia, the overall building of the Sailor School has been basically completed, and some supporting buildings will be built to add some software, and classes will be opened in the spring of next year......

Kong Yingda stood still, first looked up at the gloomy sky, then looked back at Fang Jun with a lost face, and asked, "Why are you so disappointed?" Do you want to do something with this school? ”

Fang Jun said casually: "Of course you have to do something, then, it's not what you think......"

As soon as the words came out, he realized the meaning of Kong Yingda's words.

Fang Jun couldn't help but smile bitterly: "After such a long period of contact, although our family has a difference in generation and age, it can be regarded as a friend who has forgotten the year." Don't you know the character of the younger generation? In fact, he is the most lazy in his bones, but he will never fight for anything that can be lazy and push it to others, so how can he have such a rebellious mind? The younger generation has never had the slightest ambition for that position, is it clear that they are looking for their own guilt......"

Kong Yingda nodded and agreed with Fang Jun's statement.

Such a academy for training naval officers will provide unparalleled prestige to those who control the academy, and those who have different aspirations will definitely benefit from it. Fang Jun's loss was unconcealed, Kong Yingda thought that this kid had something in mind......

If this is the case, it is impossible to say that you need to be persuaded by a good student.

However, Fang Jun's explanation is completely acceptable, this kid is a lazy guy, and letting him be the emperor is definitely the most uncomfortable torture......

But in this way, Kong Yingda became more and more curious.

"Then why are you so obsessed with building such a school?"

The manpower and material resources required for such a grand school are simply astronomical, and they will have to face countless years of investment in the future, which is all real money investment, and not a penny of profit can be seen!

What is the picture of such a rewarding thing?
