Water droplets slowly condensed on the stalactites clinging to the cave roof, though it would clearly take some time before they fell. Down below, the spring at the bottom of the lake continued to bubble up, quickly pooling into a shallow puddle of clear water.
Xia Ruofei marveled at the sight. Logically, with the spring constantly churning out water, the small lake should have filled up long ago. Why did the water level always remain at a specific height?
When he voiced this question, his turtle servant explained, "Master, there should be a drainage channel inside the spring. Once the water reaches a certain level, it stops rising. Even if too much water drips from the roof, the mixed, highly toxic water will just flow away through that channel. However, the stalactites drip so rarely that it hardly has any effect."
Xia Ruofei nodded and stood silently in thought.
