Xie Jiuniang paid attention to the situation outside for a moment before losing interest.
When they were on the other side of Shilin, her spiritual power had inexplicably begun to drain away, but later on, the rate of loss gradually slowed down. She suspected that perhaps they had reached the edge of the area and were now far from the dangerous place.
To walk out of Shilin was to walk out of danger.
Xie Jiuniang speculated that there might be something in that place.
That entity was continuously devouring the spiritual energy within a certain range. She was very curious about this secret, but unfortunately, she didn't have the guts to explore it, because she couldn't even prevent the loss of her own spiritual power earlier on.
It showed that her abilities weren't up to solving the problem.
The perilous places in the Cultivation World were dangerous precisely because of the many unknowns they contained.
