Sci-fi

Worlds overlapped, and Alien Species descended.

Strange entities emerged one after another, as the shadow of evil spread wildly.

The calm of life was shattered, and Zhang Xiaoman, inside a fish's stomach, accidentally consumed a system named “World-saving Plan”.

From then on, he became the only person among all humans with Extraordinary Power.

…

Inventing an ancient oath, he established a unique methodology, Cultivated Dark Energy, founded an organization, took Control of the Transcendent, and resisted invasions.

Well, this is actually the story of how a Big Con Man bluffed his way into saving the entire world.
