Along the road, they went deep into the Frozen Dragon Castle.
It seemed that the castle was in all directions, but after several rounds of exploration, Andrew found that most of the passages were blocked because of collapse or ice.
The remaining several passages would eventually return to the corridor on the third floor.
In other words, there was only one way to go through this seemingly stretched castle.
The deeper they went, the stronger the stench in the air became.
'There is no doubt that we are going deep into the lair of the fiend.'
The ceiling, walls, and ground were covered with a layer of brown mucus, like a mushroom blanket.
It was cold and wet, making it like the food of some creature.
"There is still no fiend ahead,"

Everyone was at a loss.
The castle was very deep inside.
But so far, no fiend had shown up.
When was the final boss going to make a move?
"Ah!"
