Creepy tunnels
These four were fully aware that this entire experience wasn't going to be a walk in the park but the deeper they went into the dark tunnels the bigger the urge to walk back up the stairs.
The only light coming through was from the door they had left open bringing to light the horrific conditions within these tunnels. The empress dowager's pavilion was a gorgeous structure, a grand palace reflecting the prestige of Hyesong nobility but in truth, it was like a golden peach with rotten insides. No one could have imagined that this beautiful structure could house such a horrible place.
The tunnel walls were made of stone and the ground wasn't plastered which meant it was basically soil with wet patches in various places. The stench was even more unbearable. It was a mix of rotten flesh, mould and plenty of other indistinguishable things.
