Structurally, Kageno Island was a gigantic metal island formed from four artificial islands.
At the center of Kageno Island stood a huge composite building. It had twelve floors and the shape of an inverted pyramid. It was not only the tallest building on Kageno Island, but also housed the city hall and other government offices, along with numerous hotels and commercial establishments, serving as the island's central hub. Beneath the sea, it contained as many as forty floors of artificial-island management facilities.
This building, less than two kilometers in diameter, served as a connecting structure that linked Kageno Island's four artificial islands together while absorbing and buffering the distortion and vibrations caused by ocean currents, wind, and waves between them.
Without this facility in operation, the four districts of Kageno Island might collide at any moment. Even if they did not collide, they would simply come apart. Thus, in terms of importance, this building could be called the most important place on the island.
The Nangong siblings lived in the western district of Kageno Island.
There was an upscale residential area here, and the Nangong Family occupied the top floor of one of its particularly luxurious apartments. Moreover, Natsuki was a National Demon Slayer Officer as well as an instructor for the Special Zone Security Force. Strictly speaking, even if the Nangong Family was not a prestigious clan, it could still be considered a wealthy household.
Luo Zhen left his room and entered the living room of the suite, which reminded him of a luxury hotel. Yawning, he trudged forward listlessly.
The next second...
"Smack!"
An inexplicable impact exploded against the bleary-eyed Luo Zhen's forehead. His drowsiness vanished instantly, and he crouched on the floor, clutching his head.
"Hmph."
Natsuki sat on a sofa some distance away from Luo Zhen.
