A Fresh Take on the Reservoir Keeper

A freak high-voltage accident while fishing whisks Su Mu away from his mundane job as a reservoir guard and throws him into a completely unfamiliar world. Just when he thinks his watchkeeping days are over, he finds himself guarding a very different body of water—except this time, it is none other than the majestic River of Time.

Blending a mundane backdrop with grand cosmic concepts creates a delightful contrast. Our protagonist's unshakeable calm amidst the turbulent shifts of time and space lends the story a unique, mesmerizing charm.

Keeping Order in the Temporal Flow

Empowered by the River Protection System, Su Mu gains absolute control over water and its denizens. His sole duty is to maintain order, stopping rogue cultivators from swimming upstream in time to alter the past or rewrite the future.

Hilarious scenarios unfold when powerful protagonists and mighty immortal emperors are forced to pay a toll fee just to cross the river. The introduction of time-travel loans adds a clever layer of financial comedy that keeps the narrative light and engaging.

Growth Born of Inner Serenity

Su Mu stands out with his quiet, down-to-earth, and composed personality. Unburdened by grand ambitions, he simply focuses on quietly and diligently fulfilling his duty as a guardian.

Though quite weak at the start, he matures steadily through various trials, gradually growing into his immense power. His interactions with the White-Robed Female Emperor add a tender, subtle emotional anchor to his journey.

Power System and Cultivation Realms

The novel builds a rich, meticulously structured cultivation system. Su Mu's progression in his cultivation level is deeply tied to his patient accumulation of power and his expanding mastery over spacetime.

The cultivation stages include:

• None
• Qi Cultivation, Foundation Establishment, Golden Core, and Purple Mansion
• Divinity Transformation Realm, Tribulation Crossing Realm, Mahayana Stage, and Ascension Realm
• Human Immortal, True Immortal, Earth Immortal, and Celestial Immortal
• Immortal King, Immortal Emperor, and Chaos

Key Highlights

• A highly creative premise that effortlessly turns a mundane reservoir-guarding job into a grand duty of watching over the River of Time.
• A breezy, lighthearted pace, spiced up with witty subplots like charging a toll fee and offering time-travel loans.
• A refreshingly realistic protagonist; Su Mu remains grounded, mentally resilient, and calm in the face of cosmic upheaval.
• A vast and well-structured progression system spanning from Qi Cultivation all the way to the absolute peak of Chaos.

• Supporting character dynamics lack a bit of depth, often taking a backseat to system-driven dialogue.
