Silver Fox of the Three Kingdoms

In May of the 24th year of Jian'an, it began to rain on a large scale in Yangzhou, Jingzhou.

The rain was not heavy at the beginning, and in some places it didn't even rain, and the sun was still scorching hot, such as Jiaozhou and the southern part of Yangzhou and Jingzhou. Only Jingbei and the northern part of Yangzhou at the mouth of the lower reaches of the Yangtze River began to rain.

Nanyang is in the center of the rainy season. Due to the Qinling Mountains, the upper reaches of the Li River are the center of heavy rain in Funiu Mountain, and most of them are mountainous areas. Historical floods have been severe and heavy rain has poured.

Therefore, starting from May 22, after the heavy rain came as expected, the riverbed of the Lishui River, which had a low flow rate due to the drought in the previous period, quickly filled up, and the river water began to surge, gradually overflowing the riverbed, and the water level of the river valley also began to rise. .

However, this still does not affect Cao Jun, because the valley has not been filled, and the water flow only reaches half of the entire river channel. Therefore, in order to threaten Cao Jun's camp, the water level must at least cover the entire river and start flooding to the flat ground.But in just one or two days of heavy rain, there will not be such a large water flow.

But until the beginning of June, both Cao Hong and Zhao Yan had a premonition that something was wrong.Because they expected the torrential rain to last for a day or two at most, but now it seems that it has not stopped. The torrential rain is still falling, and it is more during the night than during the day, and the whole world is covered by the torrential rain.

For this reason, they had to immediately send someone to ask for help from Yecheng, and when Cao Pi got the news that Shen Chen had dug a trench and knew that it had been raining for the past few days, he immediately sent the letter to Chang'an.

But Cao Cao had not yet received the letter. On May 26, after three or four days of heavy rain, the valley of the Lishui River was finally filled.

At this time, in the depths of Funiu Mountain, dark clouds enveloped the entire sky, and the torrential rain caused the streams in the mountains to swell.

After the upstream river valley reached its limit, the dam used to intercept the Lishui River in Funiu Mountain was finally washed away by the current. With a loud noise, finally in the afternoon of this day, the mountain torrent erupted, like a gap between heaven and earth , the whole earth trembled.

"Boom!"

"boom!"

A loud voice resounded through the world.

In Yecheng, Cai Du, who was staying behind, overlooked the Lishui River in the north. He saw a loud explosion in the Lu Mountains in the west, followed by countless mountain torrents pouring down, covering the entire valley of the plain.

The torrential rain hit Cai Du's face. He held up a bamboo mat in his hand and was wearing a coir raincoat, and the raindrops slid down the edge of the bamboo mat.

Even though it was mid-morning eclipse, the sky was black. With the slanting raindrops and the howling forest, the forest in the distance seemed to be collapsing. The forest was crumbling in the wind and rain. After the loud noise, a large number of yellow fresh The soil was washed out and many trees were washed away.

Then the nearly red muddy water flowed into the plain, and the Lushan Mountain in the west of the Funiu Mountains turned into a waterfall at this time, and an unknown number of kilometers of land was submerged. The power of nature was fully revealed at this moment.

"Captain."

A lieutenant beside Cai Du stepped forward and said, "It's too dangerous here, let's retreat east to the highlands of the Dabie Mountains."

Cai Du smiled and said: "It's okay, General Zuo once said that the topography of China is high in the west and low in the east, and the difference between the north and the south is not that big, but since the Lishui River flows south, it means that at least the topography around Yecheng is higher than that in the north. Kunyang, the flood will not come this way."

"But the inside and outside of the city have been submerged."

The deputy general looked outside the city. Yecheng is actually far away from the flood outbreak point of Mount Lu in the west, more than ten miles away.

Funiu Mountain to the west of Nanyang Passage is more than 20 kilometers away from Dabie Mountain to the east, and Yecheng is in the center, so the flash flood in the distance will not submerge this side in a short time.

But the water level has skyrocketed, and the entire Nanyang channel is covered with a layer of shallow water, and the direction of the Lishui River is continuously rushing towards that side.

Fortunately, the materials in the city had already been transferred to the higher mounds in the east, otherwise Shen Chen's army would have lost a lot of materials.

Even the temperature seemed to drop a few degrees under the pouring rain.

Cai Du said calmly: "Since the general said it, it must be right. Our city is two feet seven feet high. I stand on the tower, and I don't believe that the water can flood it. Materials can be transferred, but we must stick to it." Here, once the battle changes, Yecheng must not be lost."

"only."

The lieutenant had no choice but to leave angrily.

Now there are only two thousand soldiers in the city, although Cai Du believes that there will be no mistakes in Shen Chen's plan.

But he also has a responsibility, that is to defend Yecheng.

If the entire city is left empty, in case Cao's reinforcements arrive in time after the war, he must at least ensure that Yecheng is still under Shen Chen's control.

So after he transferred the civilian husbands, auxiliary soldiers and supplies in the rear, he had to lead the remaining soldiers to guard the city.

And just as Cai Du was watching the mountain torrent collapse more than ten miles away.

At this moment, the water level in Shen Chen's barracks in the pavilion located tens of miles away from Yecheng had obviously exceeded the ground, submerging the entire barracks, and all the ships placed on the school grounds were floating.

Shen Chen is now in a big boat in the central school yard. The boat is not a building boat, but a medium-sized fighting boat, more than ten meters long and three meters wide.

Due to the lack of time, there are no extra-large ships, only small and medium-sized ships. There are currently three warships, and the rest are basically small troop carriers such as Maotu, Lulu, and Walking Ships that can carry 30 people.

But the roof was built on the boat, and the rainwater could not enter the cabin.When the water slowly submerged the school yard, the small troop carriers floated up, but not very high, and the warships stood still.

The main reason is that although the Lishui is overflowing now, the water level is only about one foot, just over the ankle of the person, and it is in the middle of the calf, which is not too deep.

Therefore, unless it is a small scout ship that can only take one or two people, troop carriers and medium-sized warships will definitely not be able to float.

"General."

In the cabin on the second floor of the battleship, Gan Ning opened the window and watched the big raindrops falling outside, wondering: "This boat can't float, are we overestimating the rain?"

Shen Chen sat cross-legged on the master seat of the cabin and read a book seriously, the table case was still lit with candles, when he heard Gan Ning's words, he smiled and said, "No hurry, wait a little longer."

"The main reason is that the rain will stop soon."

Gan Ning smacked his lips and said, "I've seen a city flooded by two days of rain before, but although the rain was heavy, it didn't seem to raise the water much."

"The amount of rainfall is different."

Shen Chen remembered the predicament of a city before crossing. The rainfall in that city reached [-] to [-] millimeters in three days, which is equivalent to a year's rain in three days.

The heavy rain in Nanyang is heavy, but the rainfall is definitely incomparable, after all, it is so heavy that it is still behind.

Like the Battle of Xiangfan in history, it rained for more than ten days, and the water level directly rose by five or six feet, and the height of more than ten meters submerged Fancheng. The rainfall is probably comparable to that of the city in later generations.

However, Shen Chen had previously built a large number of dams in the mountains upstream of the Lishui River. If all goes well, the dams will not be able to withstand self-destruction, and there will be a wave of floods for a short time.

Although due to the vastness of the Henan Plain, it is estimated that a large amount of floodwater will be carried away, but if the water level rises a few feet, it should be possible to sail.

"Woooooooooo!"

At this moment, a desolate horn sounded from behind.

Gan Ning jumped up immediately, but he bumped his head because of emotion, but he didn't care about the headache, he turned to Shen Chen and said, "General, you're here."

"I heard, order to open the gate of the camp!"

Shen Chen said immediately.

"Quick, play the drums."

Gan Ning immediately got out of the hatch and shouted to the outside.

"Dong dong dong dong!"

Suddenly there was a sound of drums on the battleship.

"Hurry up!"

Hearing the sound of beating drums, the middle battalion started to move first, and the soldiers from each battalion put on coir raincoats one after another and boarded the boat in the rain.

All the soldiers in the surrounding battalions boarded the ship except for some who stayed behind.

The soldiers climbed onto the boat one after another, took off their shoes, poured out the water, and put on their shoes again.

The rain almost covered the sound of the horns, but amidst the noise of countless horns, gongs and drums in the entire camp, the soldiers finally started to march according to the previous arrangement.

The soldiers at the gate of the camp in the north began to open the camp gate. The gate of the camp was opened outwards. Almost at the moment when the bolt was taken down, the water flowed from south to north and was rushed to both sides by the water, opening the gate of the camp wide open.

Immediately on the southernmost mound of the South Camp, the soldiers who had just blown their horns watched the tumbling flood roaring towards this side, and the speed was really too fast.

Almost not long after Shen Chen gave the order, a huge current flooded directly into Dongying, where his home was near the Lishui River.

With a "bang", the outer fence of Dongying was directly broken, and then a large amount of water flowed into the camp.

Fortunately, the soldiers had climbed to the high place a long time ago, looking at the huge power of the torrent below with fear, many of them were clinging to the high oars fixed on the mound, the wind and waves were too strong, they were afraid of being blown down by the wind, or A wave came and swept them away.

But their worries are obviously superfluous. The rain this time is definitely not comparable to the Battle of Xiangfan and the catastrophic floods of the Yangtze River in later generations. It is just the normal rain in the Meiyu season in the Yangtze River Basin.

The real heavy rain is still two months away.

So the floodwater rose to a height of one foot, about [-] meters. Their earth hill was more than two feet high, and they couldn't submerge them at all. At most, their feet were wet when the waves below hit the shore.

Soon the big water flowed into the camp, and more floods spread to both sides, especially the south bank of the lower reaches of the Li River. After all, Huaxia's terrain is high in the west and low in the east.

The Wuyang garrison on the south bank of the Lishui River was the first to suffer and was directly submerged by the flood.

The water flow on the north bank was relatively low, but in this continuous heavy rain, it must not be too low. The flood continued to flow northward along the Lishui River and went straight to Cao Jun's main camp.

At this moment in Cao Jun's camp, Cao Hong was standing in the arrow tower on the earth hill, looking up at the sky, the sky was gloomy, and the cloudy weather seemed to make him breathless.

The world is dark, Shen Chenjun was only three or four miles away from them before, standing on the high ground of the earth mountain, he could see the Nanyang army barracks on the opposite bank that stretched for more than ten miles.

But now it's so dark outside that I can't see anything clearly.Occasionally, a thunderbolt illuminated Cao Hong's worried face.

He never expected that it would rain for three or four days.

Their camp and Shen Chen's camp were both located on the north bank of the Lishui River. After the Lishui River surged, the two banks naturally became the first targets of overflow. As a result, Shen Chen's army and their camps all suffered.

However, Shen Chen's army had attacked the camp many times in the past few days, digging a large number of canals outside, and the water flowed straight to his camp along the canals.The drains in the camp were completely insufficient, because the drains were connected to the Lishui River, and the Lishui River had already overflowed, and there was nowhere to drain it.

As a result, their camp was completely submerged in water. The water flowed into the camps along the gaps between the fences, reaching a depth of more than a foot, covering the calf, and rising every day. The soldiers had to migrate to high places and dirt hills .

Fortunately, they built a lot of earth hills before, and there were wooden platforms on the fence around the camp for soldiers to defend, so they could barely stay behind. Otherwise, the soldiers might have already fled away.

"General."

Zhao Yan saw Cao Hong's expression was ugly, so he comforted him: "Although our camp is flooded, Shen Chen probably won't feel well either."

"I'm afraid that he will build a ship."

Cao Hong shook his head.

Zhao Yan said with a smile: "The water is only one foot deep. A small black-topped boat with a few people may be able to go, but he has an army of tens of thousands, so how many such small black-topped boats will be built, the general can rest assured."

Cao Hong thought for a while and said, "The guards are right. I hope this heavy rain will pass as soon as possible."

Zhao Yan comforted again: "We have already sent people to Yecheng to ask for help, and the prince will definitely send people to Chang'an to be determined by the king of Wei. If we wait a few more days, the king of Wei will send reinforcements from Wuguan to help us."

"Ah."

Cao Hong nodded, suddenly remembered something, and said, "Before I told you to take good care of the granary in the army to prevent it from getting wet. How is it now?"

Zhao Yan said: "General, don't worry, everything has been properly arranged."

"That's good."

Cao Hong felt relieved.

After the establishment of the camp, the granary is also the top priority.

At that time, the construction of granaries was to build a circular high cylinder with soil on the spot. The bottom should be at least three feet above the ground, and the top should be covered with thatch to prevent moisture.

Judging from the current situation, the water flow is less than one foot, so it should not be able to flood the granary.

But Cao Hong was afraid that if the rain continued for more than ten days, if the water level rose to three feet high and submerged the bottom of the granary, it would be terrible.

Although the bottom is sealed with soil, the bottom is soaked in water, and the water may soak into the pottery granary, so Cao Hong is still very worried about this. In the past two days, Zhao Yan has asked Zhao Yan to transfer some of the grain to a higher place.

The heavy rain was still falling, and the rain water hit the wooden planks above the high oar, making a crackling sound.

Another thunder flashed in the distance.

At this moment, Cao Hong suddenly heard a strange voice, and asked Zhao Yan, "Gu Jun, did you hear that?"

"Hear what?"

"The sound of running water."

"Water flow?"

Zhao Yan turned his head to look at Lishui in the south.

The waves of the Lishui were rolling, and the sound of the water flow was very loud. Apart from the sound of rain, howling wind and occasional thunder, there was only the loud noise of the big river outside.

He said: "Not far away is the Lishui River, and it is normal to have the sound of water flowing."

"But it's getting bigger and bigger, so listen carefully."

Cao Hong's face was serious.

Zhao Yan also listened carefully, and he really heard the sound of huge waves like waves in his ears.

It gradually covered the rain, the sound of the wind, and the original flow of Lishui, and then there was a "bang", as if something had been broken.

"Boom!"

There was a loud bang between heaven and earth, and the thunder flickered again.

Cao Hong and Zhao Yan's eyes widened suddenly.

They saw that in the south, the eastern camp of Shen Chen's army was washed away.

Immediately after, a terrifying huge wave swept over the Lishui River, the waves were several feet high, rushing towards them like mountains and seas.
