When Su Mu hurriedly rushed home, he was stunned by the scene before him.

At some point, the river had surged, already flooding onto the banks. His stone house was already half-submerged, and the willow tree was submerged a few meters as well.

At this moment, the immersed willow tree was emitting a faint immortal light; he could sense the tree's very weak aura, sending a faint signal for help towards him.

This is bad, the willow tree won't make it, my home is about to be swept away, and my vegetable garden is finished!

Nannan stood on the back of the Cyan Ox, thus avoiding being submerged by the river water. Su Mu said to Nannan, "Nannan, don't come over, just wait for me here!"

....

Having said that, Su Mu treaded through the water, heading towards his stone house.

He discovered that many of his furniture, like chairs and stools, had been washed away by the water. But fortunately, these were just ordinary treasures, as the good treasures were stored in his Space Ring, carried with him.

Arriving at the vegetable garden, he found it completely submerged, with only the tallest Bodhi Tree visible, though it was also half-flooded.

His stone house didn't lose much, but the garden suffered significant losses!

Who knows how many spirit plants were drowned.

At this time, Su Mu turned his head toward the river and discovered that the flood had just come through from upstream, passing by his home only moments before.

It seemed to have reached here just a minute or two ago.

The flood peak was continuing downstream, and since he had been patrolling downstream, he hadn't noticed the anomaly immediately.

.....

Fortunately, the flood wasn't very large, raising the water level by just a few meters from usual.

Su Mu stood on the river's surface, using the Water Control Divine Technique to halt the flood peak.

However, Su Mu could only stop the flow of water over an area of five thousand square meters at a time.

But the river was so long, those five thousand square meters were insufficient, serving only to delay, not solve any problems.

Though he had halted the peak, the water from behind would continue to rush in unabated, forming a new peak when the next wave arrived, making it impossible to stop in time.

....

At this moment, Su Mu began to feel anxious.

This was the first time he encountered such a big problem while guarding the river, now somewhat out of his control, beyond his capabilities.

Su Mu's mind was racing, with the back flood peak set to reach here within at most half an hour, giving him only half an hour to find a solution.

He recalled the main method Blue Star used to manage floods in his past life, which was to divert the flood.

Diversion of floodwaters to other places could maintain the main river's water level. Otherwise, everything along the main river, all towns, would be flooded.

...

Su Mu hurried downstream along the river, looking for any tributaries that could be used for flood diversion.

But after searching for ten minutes, he failed to find any suitable tributaries for diversion.

Then, Su Mu found a tributary, with its entrance blocked by a stone dam, and behind the dam was a waterfall.

Standing above the waterfall, he looked down to find a deep basin-like reservoir about several hundred meters high.

Moreover, the current water level of the reservoir was very low and substantially vast, just suitable for flood diversion.

As long as the floodwaters from the main river could be diverted into this large reservoir, the river's flood crisis could be resolved.

Yet a problem arose.

The stone dam connecting the main river to this tributary, stretching thirty meters, needed to be pushed down to divert the flood smoothly into the tributary.

But the stone was extremely solid.

Time was running out, with the new peak approaching, reaching within ten minutes at most.

Su Mu unleashed his aura, his cultivation surging, pulling out the Silver Dagger and Stone Blade, his two strongest and sharpest weapons.

He held the dagger in his right hand, the blade in the same hand, and began hacking the dam frantically.

Su Mu discovered that, for cutting this stone, the Stone Blade was more effective than the Silver Dagger, opening a fifteen-meter wide hole in just five minutes.

Still not enough; it had to be a full thirty meters wide.

.....

When Su Mu knocked down the last piece of stone from the dam, the new flood peak had already arrived.

He stood in front of the flood peak, employing his Divine Techniques to divert it into the nearby tributary.

Thus, Su Mu stood on the water's surface, enduring for three hours, his complexion pale, already greatly spent, continually steering the floodwaters' direction, severely testing his Spiritual Power.

Were it not for his Celestial Immortal Great Perfection status and Level 5 Water Control Divine Technique, he could not have lasted this long.

.....

By the fifth hour, the main river's water level finally returned to normal, Su Mu lowered his hands, breathing heavily, nearly collapsing from exhaustion.

He quickly sat cross-legged to meditate, soon recovering.

.....

Su Mu stood atop the embankment, looking below; the hundred-meter-high reservoir was already full.

Wiping the sweat from his forehead, he sighed in relief.

Fortunately, he found such a low-lying reservoir for diverting floods; otherwise, he truly couldn't have managed it.

But still, fortunate this time's flood wasn't significant, for if it'd been a major one, his current Water Control Divine Technique wouldn't suffice.

To prevent the reservoir's water from back flooding, Su Mu rebuilt the demolished embankment, widening it by twenty meters and raising it by ten, ensuring there would be no further issues.

With everything done, the main river returned to its usual calm.

At this moment, a system notification sounded in Su Mu's mind:

[Congratulations to the host! Successfully maintained river stability, handled the flood, triggering additional causality-critical rewards!]

[1. Favor Points +500,000]

[2. Obtained Infinite Void Bottle]

The next second, a small white porcelain bottle appeared in Su Mu's hand, shaped like a narrow-necked vase, feeling quite light in his grasp.

This was the first time Su Mu obtained a system reward treasure through such a means.

He placed the small white porcelain bottle into his Dantian Space, planning to study it when he had leisure time.

This time, Su Mu directly earned five hundred thousand Favor Points!

Breaking his previous record, such was fifty thousand; it would normally take him many diligent months to earn!

Fifty thousand could convert into a five percent Affinity increase.

If a few more floods of this scale came, he might directly refine this river!

However, it remained wishful thinking, as such situations were rare, almost non-attainable. Though he'd been here for nearly three years, only one was encountered.

...

Su Mu returned home.

The flood had churned the courtyard into disarray, so he began tidying up, with Nannan helping and not idle either.

"Papa!"

"Come take a look, what is this thing?"

Nannan seemed to have found something, standing up and calling to Su Mu in the distance.
