A disaster turned Yuechen Island into a world unto itself. The entire island was sealed off, with no access by air or sea and all passage forbidden.
The people on the island were abandoned. Its population had originally numbered over ten million, but after the "green crystals" ran rampant, only a little over six million remained. Those who survived adapted to the polluted island, and some even mutated, making the situation more complicated.
After the disaster, the islanders banded together for warmth, forming numerous independent groups. The whole of Yuechen Island became a patchwork of these factions.
How will the protagonist, who has gone from ruthless to compassionate, rely on his own wits and carefully laid plans to build the ideal world he dreams of, one step at a time...?
