After ten o'clock at night, the water flow in the downstream Yangtze River Basin began to accelerate mysteriously.

Many cities far from the danger line, and many citizens still walking or relaxing by the river, heard the sound of the river's flow growing louder nearby.

"Splashing... Splish, splash..."

"What's happening?"

"Such a strong wind sound!"

"Is the wind picking up?"

"Not sure, I don't feel anything; is it windy on the river, or is it going to rain?"

The sound came from the river, and curious citizens approached the riverbank, trying to see into the river but found nothing visible in the dark. They couldn't perceive the accelerating water flow either.

"Splish, splash... Splish, splash..."

"The wind seems pretty strong."

"The wind has picked up, might rain soon, let's hurry home!"

Soon, citizens by the river dispersed and returned home, unaware of the mysterious acceleration of the Yangtze River's water flow.

Before long, the downstream Yangtze River started speeding up from the Poyang Lake area, with nearly two thousand miles of main stream accelerating, and the waters of Poyang Lake, Taihu Lake, Chaohu Lake, Hongze Lake, and Gaoyou Lake began to slowly decrease.

...

Before Lu Zheng sorted out the Yangtze's water veins, Si Lingxi had already reached the Zhujiang River area, and Liu Qingyan and Shen Ying had arrived at the Yellow River domain.

Compared to the Yangtze River's average flow of over thirty thousand cubic meters per second, the Zhujiang River only had over ten thousand cubic meters per second, while the Yellow River had just over two thousand cubic meters per second, making it relatively easier.

Si Lingxi felt the easiest; though she wasn't skilled in Water Technique, her cultivation was deep. A mere stir of her Divine Thought could envelop the Zhujiang River from source to sea, all four thousand miles of main river within her perception.

Her lips parted slightly, releasing a fragrant breeze, expanding in midair, turning into an invisible ribbon, gently falling onto the Zhujiang River below.

Subsequently, the ribbon appeared to have intelligence, spread across the Zhujiang River estuary, adhered to its surface, rapidly accelerating the water into the sea.

At the same time, the ribbon twisted and lengthened, clinging to the water's surface, expanding upstream, even extending into some major tributaries upon encounter.

Si Lingxi concealed her presence, hovering aloft, motionless. A ribbon accelerating water flow automatically formed, slowly speeding the Zhujiang River's flow, increasing its volume, while its elevated water levels gradually decreased.

Similarly, Liu Qingyan and Shen Ying had partnered up at the Yellow River, their effect not as good as Lu Zheng and Si Lingxi, but still managed to accelerate the major routes of the Yellow River in Lu Province to speed into the sea.

Within a day, the water levels of the three major water systems in Hua Country began to decelerate after continuous increase, finally reversing in the early morning, even decreasing.

...

Consequently, all this was detected by water flow monitors scattered around the banks of the three major water systems, quickly reported to various departments like meteorological bureau, flood control office, disaster reduction office, forest protection office, emergency department, and aggregated at Beidu Headquarters.

...

Three PM. 𝓯𝓻𝒆𝙚𝒘𝓮𝙗𝓷𝒐𝓿𝙚𝒍.𝙘𝓸𝙢

"Report, Zhujiang River's flow speed increases!"

"What's the situation?"

"Unknown, but the stable flow of around ten thousand cubic meters per second showed noticeable changes, reaching eleven thousand cubic meters within two hours! Local researchers have been dispatched for on-site investigation."

"Alright, noted."

...

Four thirty PM.

"Report, Yellow River's downstream, most of Lu Province, water flow increases!"

"Hmm?"

"According to Yellow River's flow monitor, from Dongping Lake section to the Yellow River Mouth, water flow accelerates noticeably, rising from a stable twenty-five hundred cubic meters to twenty-seven hundred, clearly exceeding normal fluctuation range."

"Reason?"

"Un... unknown..."

"Unknown?"

...

Six PM.

"What's happening with the Yellow River and Zhujiang?"

"Report, both locations continue to amplify, Yellow River's downstream steady at around thirty-two hundred cubic meters, increase slowed, Zhujiang River's overall flow reached thirteen thousand five hundred cubic meters, still rising!"

"Any analysis report?"

"None... Researchers and professors continue analyzing the cause."

"What's going on? Such visible water flow changes, yet no direct cause found?"

"Nothing, said it's just increased flow without any external cause."

"Continue monitoring, report frequently."

"Yes!"

...

Eight thirty PM.

"Report! Report! Yangtze River Basin has appeared too!"

"Don't rush, explain in detail!"

"Yes! Yangtze downstream rose slightly this afternoon, still within normal range thus went unreported until we emphasized monitoring flow changes, Yangtze Lake stations finally submitted data."

"Focus!"

"Yes, Yangtze's flow began rising slightly around two PM, first at the estuary, then expanded to Poyang Lake area by seven PM. Huai River area from Huainan began accelerating. An hour ago, mid-to-lower Yangtze's flow noticeably increased, from Poyang Lake down to estuary."

"Now?"

"Average flow stabilized at thirty-six thousand cubic meters!"

"Still haven't found a cause, right?"

"Yes, but all research institutes dispatched frontline researchers, professors joined analysis teams, conducting field investigations, analyzing accelerated water flow's cause."

"Maintain contact with relevant departments, update immediately if info arises."

"Yes!"

...

Eleven PM.

All related departments remained brightly lit.

Hundreds of researcher teams and related hydrological geography professors focused across lower sections of three major water systems, conducting field investigations to find river's sudden acceleration cause.

Detection boats, submarines, various analyzers, everything deployable has been dispatched, yet still no results.

"It's not scientific!"

"I've studied the Yellow River for fifty years, never encountered this!"

"No gale, no rapids, not tidal pull, same river paths, same environment, why this sudden flow acceleration?"

"If this keeps up, these rivers' downstream will replenish water capacity, thus flood alerts for the year mysteriously resolved."

"Can't sleep without clarifying the cause!"

...

Two AM.

"Report, Yangtze River area flow stabilized, fixed at forty-two thousand cubic meters."

"Report, Yellow River mid-to-lower reaches, most of Lu Province flow stable at thirty-seven hundred cubic meters, Dongping Lake's water level started declining."

"Report, Zhujiang overall flow remains above fifteen thousand, water levels begin to fall regionwide."

"Can anyone tell me what the hell is going on?"
