Later generations know: August 18 Qiantang River tide, the world famous.

However, most people do not know that from the pre-Qin period to the modern era, due to the geostrophic deflection force and the alluvial extension of sediment in the estuary, the great tides along the East China Sea have been slowly moving southward.

In the pre-Qin and Han dynasties, the tide flourished in Guangling (Yangzhou).

Wei and Jin dynasties, flourished in Wu County (Suzhou).

After the Tang and Song dynasties, it flourished in Qiantang (Hangzhou).

In the era in which Zhuge Jin lives today, the largest tide in the East China Sea occurs precisely in this Guangling City.

During the Western Han Dynasty, the Han Fu everyone and the Guangling people multiplied, and there was a praise for the Guangling tide: "Spring and Autumn Shuowang, there are big waves, the momentum is terrifying, to the north of the Jiangbei, the fierce red bank, especially rapid." ”

The name of this Fuwen was also very loud at that time, and it was similar to Jia Yi and Sima.

As for his popularity in later generations, it was lower than Jia Yi and Sima Xiangru, mainly because he was a native of Guangling, belonged to the territory of Wu in the early Han Dynasty, and served Liu Bi, the king of Wu. And Liu Bi later launched the Rebellion of the Seven Kingdoms.

Liu Bei has been in Xuzhou for less than two years, and he has never been to Guangling City, nor has he seen Guangling Chao.

Today just caught up with the biggest tide day of the year on August 18, and together with Zhuge Jin, I watched the grand occasion of the world at the mouth of the Hangou River.

By the way, after the tide recedes, let's see how many fish Zhuge Jin can catch in the latest improved version of the drift gillnet put down.

It's a pleasure.

However, the time to wait for the tide was too boring, so Liu Bei continued to discuss with Zhuge Jin about the improvement process of this flow gillnet.

Zhuge Jin also had nothing to do, so he explained slowly.

He first took the first bamboo gillnet to Liu Bei, Liu Bei is a layman, and he didn't see the clue at first glance.

Then I compared it with the second version, and found that the bamboo slices of the first version were arranged parallel to the direction of the net extension on the wide side, while the second version lined up the bamboo slices vertically, facing the direction of the water flowing on the side.

This principle is easy to understand, and Liu Bei himself understands it.

Obviously, the first version must have been put under water, and the resistance was too great when it was washed by water, and the area facing the water was too wide, and it was easy to be washed away. In the second version, the thin side is facing the water flow, which can separate the water potential, and it is much more stable.

Then Liu Bei watched the third edition, and on the basis of the second edition, a perforated hemp rope was added to the bottom and a large stone was tied to further prevent it from being washed away.

But the third version is obviously not good enough, Zhuge Jin said, he did the test and found that although the bottom of the stone will not be washed away, but it will still be skewed, no longer facing the current head-on, blocking the fish, the cross-sectional area of the fish and the stinging fish has become much smaller.

So in the final fourth edition, he also added an additional complete and watertight empty bamboo on the top of the bamboo stick, and used the hollow bamboo tube as a buoy to ensure that after the tide washes, the buoyancy will always pull this end up.

In this way, a net in the middle, a buoy on the top, and a big stone at the bottom, can be regarded as completely stable in the upper and lower positions, even if it is crooked, as long as there is buoyancy, it can automatically return to the right.

Zhuge Jin didn't know how to build a flow gillnet before, but only knew a concept of thinking.

But who made him have strong logical thinking, and the spatial geometric imagination is very powerful, and he has been drumming it out after ten days before and after, and after a few more experiments.

Liu Bei originally felt that the final product was very rebellious, but now after looking at Zhuge Jin's "R&D process" and so many intermediate iterations, he completely believes that Zhuge Jin's way of thinking is far more rebellious than the results themselves.

He didn't look at it on a spur of the moment, or from somewhere else.

People are really good at brains, see the subtleties, and can immediately start to solve problems when they encounter them.

"A small bamboo dumpling, in just a few days, created the fourth generation, each generation slightly improved, the agility of intelligence, is really rare in ancient and modern times."

When Liu Bei sighed, the thunder was rolling in the distance, and he looked up at the sky in surprise, but saw that although the weather was cloudy, there was no thunderstorm.

Immediately, under the explanation of the attendant, I learned that this was not thunder, but the sound of the tide.

Liu Bei also felt a pang in his heart, like thunder and wind that would change, sitting upright and solemn, ready to look at the wonders of the world.

Zhuge Zhan didn't feel surprised, when he was studying and working in a provincial city in his previous life, he saw a lot of tides.

But the solemn performance of others also infected him, so he also showed a bit of awe of nature.

Soon, the tide in the distance was like a line, rolling up against the current from the direction of Hailing, and the natural flow of the surging Yangtze River was pushed back.

Especially when the crest of the river wave collides with the tide against the tide, a shock wave with the superposition of the crest is formed, which can instantly rise to the sky, and then dissipate suddenly, which makes a group of outsiders from the inland amazed.

Liu Bei doesn't read poetry, he only has his heart at the moment,

And Sun Gan is the one who reads the most poems among the people, and he can't help but pick out a few paragraphs of the "Guangling Chaofu" and Wang Chong's Fuwen of this dynasty (Eastern Han Dynasty).

When Liu Bei heard this, he couldn't help pouting: "The endowment of the ancients, what is there to sing?" Gongyou has Yaxing, and you can make your own endowment. ”

Sun Qian hurriedly smiled: "I am only a shallow learner, and I am in front of the great works of the princess, and it is really embarrassing to write it." ”

Liu Bei was a little unconvinced: "That official document endowment, can it be as powerful as Ziyu?" ”

Zhuge Jin next to him never expected that this could set himself on fire, and hurriedly hinted: First of all, I didn't provoke anyone......

Liu Bei said: "I know people with outstanding intelligence, and they know everything. Cifu is a small way, maybe Ziyu disdains to specialize, but with your wisdom, even if you take a few words casually, it is definitely not bad, and it can be regarded as a trip here - if I can chant, I have to come up with a few words, but unfortunately I can't at all. ”

Zhuge Jin originally refused to be a copyist, because he felt that it was boring to pretend to be forced to slap his face. He doesn't need to be famous among the general public now, those things are worthless to him, and they prevent him from keeping a low profile.

But listening to Liu Bei's sincerity, he also knew that Liu Bei was not a yin and yang weird squeeze, but really felt that "Lao Tzu is uneducated, and he walks the world in a slot", and he wanted to find a few words to vent with emotion.

That being the case, Zhuge Jin had a thought: "Since the general has a block in his chest that he can't express, and he doesn't know how to describe it when he sees the superb scene, Jin will casually say a few words." However, even if it is a recitation of poetry, it is always necessary to add some color. ”

Liu Bei was stunned for a moment, and then overjoyed.

Zhuge Jin has always been a guest secretary, detached from everyone, and has helped so much, but he has never been able to repay him. It's rare that Zhuge Jin actually opened his mouth to talk to him about the conditions, and of course Liu Bei couldn't wait to return the favor quickly:

"Yo, Mr. is omnipotent, how can he still use me? It doesn't hurt to open your mouth though! ”

Zhuge Jin also made a small fuss, called the people sent by Mi Zhu next to him, and said to Liu Bei: "This Tang brother, as well as a few people next to him, are all good at running river boats, and Zizhong temporarily assigned them to me, and also brought three hundred guards and sailors.

Jin asked the general about it: I will compose a song for this Guangling Chao in a while, and if the general is satisfied, he will ask Zizhong to officially transfer these three hundred people, as well as their boats and granges, to me.

It's not that I'm greedy for money, but after this incident, I need some free manpower to go to Yuzhang, Jiangxia, Xiangyang and other places to investigate and secretly visit and explore the recent situation of my uncle and brothers.

The general also knew that his uncle was persecuted by Zhenrong and Zhu Hao last year, and now he only knows that he was defeated and retreated westward, but he doesn't know the specific news, and he has to investigate slowly. A few days ago, Guangling was very eventful, and I didn't dare to use the general's soldiers to deal with family affairs. ”

Of course, Liu Bei didn't wait for him to finish speaking, and immediately said that all of these were transferred to Zhuge Jin. Mi Zhu will say it in person, even if it is a loan.

Zhuge Jin saw that he agreed happily, so he said: "Okay, then my poem is worth three hundred guards." Since you have played all the games, it is better to take this method of gillnet and set up a lottery together.

After watching the tide for a while, after putting down the bamboo dumplings, I bet that today's two hundred dumplings can catch more than 20,000 catties of fish when the nets are collected at night, that is, 100 catties per sting.

If I can't do it, my method of gillnet will be given to the general for nothing. But if I can do it, I can be regarded as alleviating the urgent need for military food in Guangling, and there will be a request at that time:

In the future, Tang Guang and the others will find out the details of my uncle's whereabouts, and if his situation is critical, he will ask the general to borrow thousands of my soldiers and horses, and accompany the army's military supplies, for a few months, to cross the river to save my uncle. ”

Liu Bei didn't say a word, and agreed again: "This is also what it should be, if it weren't for Ziyu's strategy, I am afraid that most of the more than 10,000 men and horses of our army have fled now, or have become dry bones in the grave." When Huaiyin was besieged and Xiapi was stolen, how desperate was the situation of our army?

Today's life is all given by Ziyu. So even if this bamboo dumpling can't catch fish, if you can find out Uncle Ling's whereabouts in detail and are indeed in danger, Bei will borrow your soldiers and horses. It's just that in that case, there is no way to guarantee the military supplies with the army, so Ziyu has to raise it himself. ”

When Liu Bei talked to him, he was completely open to his own people, and there was no concealment.

Tell him the truth: You can't help me catch fish, and I will borrow your soldiers, but not rations, because I myself will starve to death. If you can still help me catch a lot of fish, and my own soldiers will not starve to death, then I will borrow your soldiers and give you back the rations for your army.

It makes sense.

"Happy."

The other party was refreshing, and Zhuge Jin was also cheerful, and he ordered others very undisciplinedly: "Come on!" ”

It's a pity that no one brought pen and ink with him when he was playing in the wild, and the scene was embarrassing.

Seeing this, Liu Bei hurriedly pulled out one of his double-strand swords, lent it to Zhuge Jin, and pointed to the river beach on the side:

"It's better to use a sword to depict on the river beach, and you don't have to worry about beauty and ugliness, and you can copy it again when you go back."

Zhuge Jin looked around and found that there was indeed no better solution, so he took the sword and slashed crookedly on the sand:

"Hundreds of miles heard thunder, and the strings were temporarily stopped.

Fuzhong even rode out, and waited for the tide on the river.

The clouds are shining in autumn and the sky is wide in the East China Sea.

The waves are like snow, and it is cold to sit down. ”

This is a poem of the ancients that he saw in his previous life in the provincial capital, when he went to Wangjianglou to watch the tide, and it was composed by Meng Haoran in the Tang Dynasty.

Now I have to say sorry to Lao Meng, and then change the name of the place slightly, and everything related to Qiantang is changed to Guangling, and it can be used.

"Good poetry, really good poetry." Liu Bei didn't know the grammar, but he saw that it was catchy, quite in line with the five-word Han Yuefu, and it was very imposing, so he felt very powerful, and he followed it aloud at the moment.

After Zhuge Jin finished writing, he put down his sword and reminded the others: "Don't be a good poem, the tide has reached the top, hurry up and take advantage of the highest water level to sink these bamboos!"

Also, don't tell the public that I wrote this song. The reputation is too big, it is not convenient to travel around, looking for uncles and brothers, and it is easy to be targeted by bad people. ”

Zhuge Jin knows that he still has a lot of tasks to go out in the future, so it is better to keep a low profile for the time being, which will help his life safety.
