It turns out there's a shimmering azure Water Storage Pearl at the bottom of the pool.
[Water Storage Pearl, an item that can store water. Wearing it reduces damage from water-based skills.]
Not all the underground river water is being stored away by the Water Storage Pearl; the Pearl's capacity isn't that vast.
Instead, the Water Storage Pearl is nurturing itself, absorbing a large amount of water to grow.
"A level-three Water Storage Pearl can store fifty-eight tons of water. If left here to continue nurturing, it might break through to level four."
Li Cunxu won't leave it to nurture further, because waiting for it to reach level four would take forever. Besides, this is a public resource secret realm, and if left until the next visit, it might be taken by someone else.
However, Li Cunxu doesn't immediately interrupt its nurturing. If he does, without it absorbing the underground river water, the water here will quickly rise.
