Who designed this underworld dungeon?

Description

In order to survive, Gong Qiying, who unfortunately became the master of Thane Dungeon, had to build his dungeon into an incomparable "underworld"
The door [cannot be opened from this side]
[Teleport trap triggered] treasure chest,
The 365-mile journey from the birth point to the BOSS room without any resting place
Monster knights with big bows on both sides of the single-plank bridge,
The insidious Sixth Man sneaks up on you around the corner,
There are also cesspits, poisonous pools and hidden roads that must be appreciated...
There are also masters such as Isshin Ashina, Furnace Knight, Passionate Golden Lion, Blue Eyes White Dragon, Scourge Legion, etc. who will bring you unexpected surprises!
The flaming straight sword, the wet scythe, the left bow sword, the oath of gold and stone, and the flames give me strength. All kinds of unique rewards will make you happy!
Gong Qiying: In my dungeon, the most important thing is for all the adventurers to have fun!
