Relying on modern equipment such as water guns and drones, he helps Archon Xi He resist crystal beast attacks and explores the ark's secrets.

Lin Shen unites with the Xi Guang tribe and awakened treasure picker forces to awaken the ark, defeating the star swallower with the Milky Way main cannon, guarding two worlds, and building a bridge connecting heaven and earth.
