Ancient Ruins Master Terminal Location - Genshin Impact - Version 5.6

The Ancient Ruins Master Terminal in Genshin Impact Version 5.6 is associated with the new world boss, Secret Source Automaton: Overseer Device, located in Natlan. Specifically, this boss and its related terminal are found in an underground cavern in the Atocpan region, west of Toyac Springs.
To reach the Ancient Ruins Master Terminal and the boss:
Start at the surface teleport waypoint near Toyac Springs in Natlan.
Head south from the waypoint toward a wooden plank bridge over a ravine.
Drop down through the ravine to access the underground cavern entrance.
Inside the cavern, you’ll find the Secret Source Automaton: Overseer Device, and the Master Terminal is part of the mechanics tied to this boss encounter.
This location is also linked to the Investigator of Ancient Ruins World Quest, which may trigger while exploring the Atocpan area. Completing this quest can provide additional context and rewards, including 30 Primogems. The terminal itself is likely part of the puzzle or activation mechanism for the boss fight.
