A botched rescue mission with an unknown objective cost Zhou Yu his team members, while leading him progressively closer to the multinational biotech corporation Juli’s research core.

In order to protect his botanist younger brother Zhou Qing, Zhou Yu accepted employment under the Juli Corporation, and is dispatched to a parallel world—Nibelungen.

Nibelungen’s biological systems are completely different from the world Zhou Yu is from. To live in this place, Zhou Yu must follow three great laws:

The first law, fear is the sign of the hunted, so you must never show fear.

The second law, the more beautiful an organism is, the more dangerous they are. Do not approach them, and do not trust them.

The third law, do not be misled by the mimicry of S rank organisms. They understand your mind, and they know how to entice you. Always remember that they have no human emotions or love. All humans are no exception to them.

Finally: We wish everyone can live happily in Nibelungen.
