As you explore Wuthering Wave's new Mt. Firmament area, added today in the 1.1 update, you may come across a strange building surrounded by a red laser grid.

Inside this strange building is what appears to be a puzzle, a chest, a few items and, most importantly, no way to get in, at least at first glance.

Inside the building in the Loong's Ridge region of Wuthering Waves, you'll see a moving platform that is out of reach behind the red laser grids.

Here you need to switch to a character with a ranged attack or the ability to shoot the moving platform towards the door until you reach the glowing blue button. Yes, it's that simple.
