In a world where alien mutations intersect with human technological heritage, survivor Eli leads a group of displaced humans through ruined cities, alien wilderness and extreme tests. He formed an unexpected alliance with the alien leader Sarena, and constantly encountered cultural conflicts, historical misunderstandings and survival challenges between the two parties. There are three main story lines: Eli's struggle for the rebirth of the territory, the internal power struggle and mutation crisis of the alien tribe, and the scientist Bailey deciphering the mystery of the alien inheritance. After many ups and downs, Eli and Salena found consensus in self-doubt and redemption. In the end, humans and aliens worked together to solve the epic crisis, and the world ushered in an unknown new era.
