Unlike what Churu expected, the medieval times underground dungeon she imagined wasn't what welcomed her. It wasn't being lighted by torches, there were no rusting cages or unrefined walls.
Rather, the underground base appeared to be just an extension of the house. However, though there are furniture and lounges, there were also doors that one must see to know what lies inside.
The noises Churu heard earlier, sadly, it was just the opera song resounding across the spacious hall. And yet, no inhabitant could be seen around to listen to the song. The only one in there was Louis Lu who was heading to a certain door.
When Louis Lu arrived in front of a metal door, he looked up — specifically to the CCTV. The camera slightly moved as if scanning the person standing in front of the door before a loud mechanical sound assailed their ears.
