This mountain cave is ten zhang high and over a hundred zhang wide, extremely spacious.
At a spot deep within the cave, an underground river flows through, and in the middle of the river, there is a small riverbank merely one zhang wide, where a lone eerie tree grows.
The whole tree is pitch black, about three to four inches thick and only four to five feet tall, with smooth branches that gleam with a luster within the darkness.
On the branch tips hang crimson leaves, long and narrow, each shaped like an art piece made of jade, emitting red light from inside out, subtly illuminating the cave space.
In addition...
Eight fruit, the size of a fist, hang from the tree branches, their surface also crimson, occasionally glimmering.
On one of the branches, a section remains where a fruit seems to have been plucked.
"So that's how it is..."
Turns out the Mountain Demon's fortune lies here.
