At around ten o'clock in the evening, the water flow in the lower reaches of the Yangtze River began to accelerate strangely.

In many cities that are far from the danger line, there are still many citizens walking along the river to enjoy the cool air. At this time, they heard the sound of the river flowing not far away, which began to slowly become louder.

"The wind is blowing?"

"I don't know, I can't feel it. Is it the wind blowing on the river, or is it going to rain?"

Voice Coming from the river, curious citizens came to the riverside one after another. When they looked into the river from the shore, they found that it was so dark that they could not see anything, and they could not see the acceleration of the water flow at all.

　"Crashing... rushing..."

"It feels like the wind is quite strong?"

"The wind is picking up, it may rain. It’s raining, go home quickly!”

Soon, the citizens along the river dispersed and went home, but no one noticed the strange acceleration of the Yangtze River’s flow.

Soon, the water flow of the nearly 2,000-mile main stream in the lower reaches of the Yangtze River, starting from the waters of Poyang Lake, began to accelerate, and the water levels of Poyang Lake, Taihu Lake, Chaohu Lake, Hongze Lake, and Gaoyou Lake also began to slowly decline.

　…

Before Lu Zheng sorted out the water veins of the Yangtze River, Si Lingxi had already arrived in the waters of the Pearl River, and Liu Qingyan and Shen Ying had also arrived in the waters of the Yellow River.

Compared to the average flow rate of the Yangtze River of more than 30,000 cubic meters per second, the Pearl River is only more than 10,000 cubic meters per second, and the Yellow River is only more than 2,000 cubic meters per second, so it is relatively easy. a lot of.

Si Lingxi is the easiest. Although she is not good at water magic, she has the foundation of cultivation. With a thought, the main river of the Pearl River, which is four thousand miles from the source to the mouth, is all in her. shrouded in induction.

Tan opened her mouth slightly, and a stream of fragrant wind was blown out of her mouth. It stretched out in mid-air and turned into an invisible streamer, gently falling on the Pearl River below her. superior.

Immediately after, the streamers seemed to have intelligence, and they were laid flat near the mouth of the Pearl River, close to the river surface, and the river water surged rapidly, causing the river water to accelerate into the sea.

At the same time, the streamers swayed gracefully, getting longer and longer, sticking to the water surface, and began to spread upstream. Even when they encountered some major tributaries, they would spread into the tributaries for some distance.

Si Lingxi hid her figure and was suspended in the sky. She did not move, shake, or raise her hands. A streamer that accelerated the flow of water took shape by itself, and began to slowly accelerate the flow of the Pearl River, making the Pearl River water flowThe water level has increased, and the water level, which has been high for several days, has gradually dropped.

The same goes for the Yellow River. Liu Qingyan and Shen Ying joined forces. Although the effect was not as good as Lu Zheng and Si Lingxi, it also accelerated the flow of water in most of the Yellow River's trunks in Lu Province and began to flow into the sea.

In just one day, the water levels of the three major river systems in China began to slow down from rising, and finally stopped increasing in the early morning, and even began to decrease in reverse.

　……

All of this was, of course, detected by the current detectors scattered along the banks of the three major river systems, and was quickly fed back to the meteorological bureaus in various places. , Flood Control Office, Disaster Reduction Office, Forest Prevention Office, Emergency Department and other departments, and summarize them to the Beidu headquarters.

　……

Three o’clock in the afternoon.

“Report, the water flow in the main stream of the Pearl River has accelerated!”

“What is the situation?”

“The situation is unknown, but it has been stable at one flow per second. The water flow rate of about 10,000 cubic meters has changed significantly, reaching 11,000 cubic meters in two hours! The local area has sent researchers to conduct on-site inspections."

"Okay, I understand."

　……

　Four-thirty in the afternoon.

“Report, the water flow in most parts of Shandong Province is accelerating in the lower reaches of the Yellow River!”

“Huh?”

“According to the Yellow River flow detector It shows that from the Dongping Lake section to the section where the Yellow River mouth enters the sea, the water flow has accelerated significantly, rising from a stable 2,500 cubic meters to 2,700 cubic meters, significantly exceeding the normal fluctuation range."< br />
　“What’s the reason?”

　“No…I don’t know…”

　“I don’t know?”

……

Six o’clock in the afternoon.

“What is the situation of the Yellow River and the Pearl River?”

“The report shows that the water flow in the two places is still increasing, and the lower reaches of the Yellow River have stabilized at around 3,200 cubic meters. , the rising rate has slowed down, the flow rate of the entire Pearl River has reached about 13,500 cubic meters, and it is still rising!"

"Is there an analysis report?"

"No... no, researchers and professors are still analyzing the cause."

"What's going on? The water flow has changed so much that it can be seen with the naked eye, but now even the direct cause has not been found?"

"No, it is said that the water flow is just accelerating, there is no external reason."

　“Continue to monitor and report at any time.”

　“Yes!”

　…

　8:30 pm.

　"Report! Report! It has also appeared in the Yangtze River Basin!"

　"Don't worry, elaborate!"

　"Yes! In fact, the lower reaches of the Yangtze River have There was a slight increase in the afternoon, but it was still within the normal range, so the inspector did not report it. The Yangtze River monitoring station did not report the data until we issued instructions to pay attention to flow changes."

"Let me talk about the important point!"

"Yes, the water flow of the Yangtze River began to increase slightly from about 2 o'clock in the afternoon, first at the mouth of the sea, and then gradually spread to the Poyang Lake area around 7 o'clock in the afternoon. The waters of the Huaihe River have also begun to accelerate from the Huainan area. Starting an hour ago, the water flow in the middle and lower reaches of the Yangtze River began to increase significantly, starting from Poyang Lake and flowing down to the mouth of the sea."

"What now?"

　“The average water flow rate has now reached about 36,000 cubic meters!”

　“We still haven’t found the reason, have we?”

"Yes, yes, but various research institutes have sent out front-line researchers, and professors from various schools have also joined the analysis team. They are conducting on-site inspections to analyze the causes of the accelerated water flow."

"And related Keep in touch with the department and report any news at any time."

"Yes!"

...

It's eleven o'clock in the evening.

All relevant departments are still brightly lit.

Hundreds of researchers and professors of hydrogeology were gathered in the middle and lower reaches of the three major river systems to conduct on-the-spot investigations to find the reason for the sudden acceleration of the river water.

Testing ships, submarines, and various analyzers were all available, but the result was still nothing.

“This is unscientific!”

“I have studied the Yellow River for fifty years and have never encountered such a situation!”

"There are no strong winds, no rapids, no tidal gravity, the same river channel, the same environment, why does the water flow suddenly accelerate?"

"If this continues, the downstream of several rivers can store water again. If the water is gone, this year’s flood warning will be lifted inexplicably.”

“No, I can’t figure out the reason, I can’t sleep!”

…

Two o’clock in the morning.

“Report, the water flow in the Yangtze River waters has stabilized,It is fixed at about 42,000 cubic meters. "

" Reports indicate that the water flow in most of the middle and lower reaches of the Yellow River in Shandong Province has been stable at around 3,700 cubic meters, and the water level in Dongping Lake has begun to decline. "

" "The report shows that the flow of the entire Pearl River remains above 15,000, and water levels in various places have begun to decline." "

"Who can tell me what the hell is going on? ”
