The Old Plumbing Entrance is a Secret Area in 异度神剑 2. It is located on the Lower Level of the Empire of Mor Ardain.
The Old Pluming Entrance can be reached from the Mine Elevator Skip Travel point on the Upper Level of Mor Ardain, by calling the elevator to the platform, riding it down, and then exiting the elevator to the left. The ladder into the large pipe must be climbed and the 热能 Exhaust Fork is reached by continuing forward. There is a valve with a Field Skill check that keeps the door shut. It requires Super Strength level 3 and Fortitude level 3 to open the door. The Secret Area is accessible by proceeding through the door and heading all the way to the end of the pipe. The hallway in between the 热能 Exhaust Fork and the Old Pluming Entrance also leads to the Pipe Maintenance Office.
