It is well known to future generations that the Qiantang River tide on August 18th is famous all over the world.
But most people don't know that from the pre-Qin Dynasty to modern times, due to the geostrophic deflection force and the alluvial extension of river mouth sediments, the spring tides along the East China Sea have been slowly moving southward.
In the pre-Qin and Han dynasties, the trend flourished in Guangling (Yangzhou).
During the Wei, Jin and Six Dynasties, it flourished in Wu County (Suzhou).
After the Tang and Song Dynasties, it flourished in Qiantang (Hangzhou).
In the era in which Zhuge Jin lives, the largest tidal wave in the East China Sea happens to be in Guangling City.
During the Wenjing Dynasty of the Western Han Dynasty, a famous Han poet and a native of Guangling wrote a poem praising the tide in Guangling: "At the beginning of spring and autumn, there are often big waves with terrifying momentum. When they reach the north of the Yangtze River, they hit the red bank, which is especially rapid."
The name of Meicheng's Fuwen was also very famous at that time, and it was known as Jia Yi and Sima Xiangru.
As for his popularity in later generations being lower than that of Jia Yi and Sima Xiangru, the main reason is that he was from Guangling, which belonged to the state of Wu in the early Han Dynasty, and served King Liu Bi of Wu. Liu Bi later launched the Seven Kingdoms Rebellion.
Liu Bei had entered Xuzhou less than two years ago. He had never been to Guangling City or seen the Guangling tide.
Today happened to be the hottest tide day of the year on August 18th, so I went with Zhuge Jin to watch the grand scene at the mouth of the Hangou River.
By the way, wait until the tide recedes to see how many fish Zhuge Jin can catch with the latest improved version of the drift gill net.
What a joy.
However, waiting for the tide was too boring, so Liu Bei continued to ask Zhuge Jin for advice on the improvement process of the gill net.
Zhuge Jin had nothing to do, so he explained slowly.
He first took the first bamboo gill net and showed it to Liu Bei. As a layman, Liu Bei didn't see any clues at first glance.
Then I compared it with the second version, and found that the wide side of the bamboo slices in the first version was arranged parallel to the direction in which the net extended, while in the second version, the bamboo slices were arranged vertically, with the sides facing the water flow. direction.
This principle is easy to understand, and Liu Bei understood it himself.
Obviously, the first version must have had too much resistance when it was washed away by water after being put under water, and the water-facing area was too wide, so it was easily washed away. In the second version, the thin side faces the water flow, which can separate the water potential and make it much more stable.
Then Liu Bei looked at the third version. Based on the second version, perforated hemp ropes were added to the bottom and large rocks were tied to further prevent it from being washed away.
But the third version is obviously not good enough. Zhuge Jin said that after conducting experiments, he found that although the stones tied to the bottom will not be washed away, they will still be washed away and they will no longer face the current head-on, blocking the cross-section of fish and sticklebacks. The area has become much smaller.
So in the final fourth edition, he added an additional hollow bamboo tube that was completely watertight on the top of the bamboo canopy, and used the hollow bamboo tube as a buoy to ensure that after the tide washed over, the buoyancy force would always pull this end upward.
In this way, a net in the middle, a buoy on top, and a big rock at the bottom can be considered to be completely stable up and down. Even if it is tilted, it will automatically return to the right position as long as there is buoyancy.
Zhuge Jin actually didn't know how to make a gill net before, he only knew a concept.
But who told him that he has strong logical thinking and is good at imagining and deducing spatial geometry. He worked it out for more than ten days and several more experiments.
Liu Bei originally thought that the final product was unbelievable, but now after seeing Zhuge Jin's "development process" and so many intermediate iterative versions, he was completely convinced: Zhuge Jin's way of thinking was far more unbelievable than the result itself.
He definitely didn't rely on some flash of inspiration or seeing it from elsewhere.
He has a really good brain, knows the smallest things, and can immediately start to solve problems when encountering them.
"A small piece of bamboo can actually create the fourth generation in just a few days. Each generation is slightly improved, and the agility of intelligence is rare in ancient and modern times."
While Liu Bei was sighing, thunder was rolling in the distance. He looked up at the sky in surprise and saw that although the weather was cloudy, there was no thunderstorm.
Soon after the attendant explained, I learned that this was not the sound of thunder, but the sound of the tide.
Liu Bei also felt a chill in his heart, like thunder and wind, he sat upright and solemnly, ready to admire the wonders of the world.
Zhuge Zhan was not surprised. In his previous life, when he was studying in college and working in a provincial capital, he had seen a lot of great tides.
But the solemn expressions of others also impressed him, so he also showed some respect for nature.
Soon, the tide in the distance was like a line, rolling upstream from the direction of Hailing, pushing back the natural current of the surging Yangtze River.
Especially when the crest of its own river wave collides with the reverse tide, a shock wave with superimposed wave crests is formed, which can instantly rise into the sky and then dissipate, making a group of inland outsiders marvel.
Liu Bei doesn't read poetry. At this moment, he only feels like shit in his heart.
Sun Qian was the one who read the most poems and poems among all the people. He couldn't help but recite a few passages from Mei Cheng's "Guangling Chao Fu" and Wang Chong's poems from this dynasty (Eastern Han Dynasty).
Liu Bei couldn't help but curl his lips after hearing this: "What can be said about the ancient poems? Gongyou is elegant and elegant, so he can compose his own poem."
Sun Qian quickly apologized and said, "I have little talent and little knowledge. Meigong's masterpieces are precious and precious. It is really embarrassing to write them down."
Liu Bei was a little dissatisfied: "Can that official gift be as powerful as Tzuyu?"
Zhuge Jin, who was standing next to him, never expected that this would cause him to get angry, so he quickly hinted: First of all, I didn't provoke anyone...
But Liu Bei said: "I have always known people with extraordinary talents and wisdom. They know everything about everything. Ci and Fu are a small way. Maybe Ziyu doesn't bother to study it, but with your wisdom, even if you just utter a few sentences, it will definitely not be wrong, and it counts. This is the end of the journey - if I could chant, I would be able to say a few words, but unfortunately I can't do it at all."
Zhuge Jin originally refused to be a copycat because he thought it was boring to pretend to be a slap in the face. He doesn't need to be famous among the general public now. Those things are of no value to him and prevent him from living a low-key life.
But listening to Liu Bei's sincere words, he also knew that Liu Bei was not trying to get away with it out of spite, but sincerely felt that "I'm so uneducated, I can go all over the world with just one word of shit", and he wanted to find a few words to express his emotions at the right time.
In this case, Zhuge Jin had a thought: "Since a general has a blockage in his chest and cannot express his feelings, and he sees a beautiful scene but does not know how to describe it, Jin just uttered a few sentences casually. However, since he is reciting poems and poems, he must add some color."
Liu Bei was stunned for a moment, then overjoyed.
Zhuge Jin has always been a guest, aloof from everyone, and has helped so much, but has never been able to repay him. It was rare that Zhuge Jin actually opened his mouth to negotiate terms with him. Of course Liu Bei was eager to return the favor quickly:
"Hey, sir, you are omnipotent, but you still have some use for me? There's no harm in asking!"
Zhuge Jin just made a small fuss, called out to the few people sent by Mi Zhu next to him, and said to Liu Bei: "This brother Tang, and the others next to him are all good people running river boats. Zizhong temporarily assigned them to me." Yes, he also brought three hundred guards and sailors.
Jin asked the general: I will compose a song for the Guangling Chao in a while. If the general is satisfied, he will ask Zizhong to formally donate these three hundred people, their boats and farms to me.
I am not greedy for wealth, but after the incident here, I need some free manpower to go to Yuzhang, Jiangxia, Xiangyang and other places to conduct overt and covert inspections to find out how my uncle and brothers are doing.
The general also knows that his uncle was forced by Zuo Rong and Zhu Hao last year. Now he only knows that he was defeated and retreated to the west. However, he does not know the specific information and has to investigate slowly. There was a lot of trouble in Guangling the past few days, and I didn't dare to use the general's troops to deal with family matters. "
Of course, Liu Bei didn't wait for him to finish speaking, and immediately said that he would transfer all these to Zhuge Jin. He would tell Mi Zhu personally, even if it was a loan instead of a gift.
Zhuge Jin saw that he agreed readily, so he said: "Okay, then my poem is worth three hundred guards. Now that we have played with it, why not use the gill net method and set it up as well?" Luck.
After watching the tide for a while and putting down the bamboo nets, I bet that with these two hundred nets today, I can catch more than 20,000 kilograms of fish when I close the nets at night, that is, one hundred kilograms per bamboo net.
If I can't do it, my gill net method will be given to the general in vain. But if I can do it, I can be considered to have alleviated Guangling’s military food crisis. Then I have another request:
In the future, Tang Guang and others will find out the details of my uncle's whereabouts. If the situation becomes critical, they will ask the general to lend me thousands of troops and horses, along with military supplies, for several months to cross the river to rescue my uncle. "
Without saying a word, Liu Bei agreed again: "This is right. If it weren't for Ziyu's plan, most of the more than 10,000 troops in our army would have fled or become withered bones in the graves. Huaiyin was surrounded and fell. How desperate was our army's situation when Pi was stolen?
The way I can survive today is all thanks to Tzuyu. So even if you can't catch any fish with this bamboo raft, if you can find out the detailed whereabouts of your uncle and if you are really in danger, I will lend you troops and horses. But in that case, the military supplies for the accompanying army would not be guaranteed, and Tzuyu would have to raise them on his own. "
When Liu Bei spoke to him, it was entirely his own people who spoke openly and without any cover-up.
Tell him the truth: If you can't help me catch fish, I will still lend you soldiers, but I won't lend you rations, because I will starve to death myself. If you can still help me catch a lot of fish and my own soldiers don't starve to death, then I will not only lend you soldiers, but also give you rations for the army.
This makes sense.
"happy."
The other party was cheerful, so Zhuge Jin was also cheerful, and he ordered others without moral integrity: "Here comes the pen!"
It's a pity that no one brought pen and ink with them during the outdoor sightseeing tour, which made the situation awkward.
Upon seeing this, Liu Bei quickly pulled out one of his two-pronged swords, lent it to Zhuge Jin, and pointed to the river beach aside:
"Why don't you just use your sword to carve on the river beach, and you don't have to worry about the beauty or ugliness, so you can copy it later."
Zhuge Jin looked around and found that there was really no better solution, so he took the sword and scratched it crookedly on the sand:
“When you hear thunder and tremors in a hundred miles, you stop playing the strings for a while.
The company rode out from the mansion and waited on the river to watch the tide.
The sun is shining, the autumn clouds are scattered, the sky is floating, and the east sea is wide.
The stormy waves come like snow, and it's cold when you sit down. "
This is an ancient chant that he saw when he went to Wangjiang Tower to watch the tide in the provincial capital in his previous life. It was written by Meng Haoran of the Tang Dynasty.
Now I have no choice but to say sorry to Lao Meng, and then slightly change the place names. Everything related to Qiantang is changed to Guangling, and it will work.
"Good poem, really good poem." Liu Bei didn't know the grammar, but seeing that it was catchy, very suitable for the five-character Chinese music, and very powerful, he felt it was very powerful, and he immediately started reading it loudly.
After Zhuge Jin finished writing, he put down his sword and reminded others: "Don't be too good at poetry. The tide has reached its peak. Hurry up and sink these bamboo rafters while the water level is at its highest!"
Also, please don’t tell others that this song is composed by me. His reputation is too great to travel around, looking for his uncle and brother, and he is easily targeted by bad guys. "
Zhuge Jin knew that he would have many far-off missions in the future, so it was better to keep a low profile for the time being, which would be helpful for his safety.
