The fog was dense along the road, and the weather was overcast. Anything beyond ten meters was invisible.
As they advanced, they could hear strange noises in the fog, as if monsters were approaching.
Ma Lin was always cautious.
Beings of the Great Demon King level were not something he could provoke.
It was very likely that this Moonlight Bottle was placed here by that ancient demon.
About two hours later, they reached the steep slope.
Then they went around the giant boulder.
Where there should have been a hole about a foot wide, there was now a plant.
It had thick, fleshy leaves of black color, with a blue-purple flower on it.
The flower smelled terrible.
Ma Lin, Brother Fa, and everyone else looked at each other in dismay.
The flower was beautiful, but its odor kept them all at a distance.
"It stinks worse than a dead mouse in a room," Picicki said.
Ma Lin examined the plant and said, "Don't you think this flower could be the key to everything?"
