Actually, before Lin Miao arrived, Si Miaoxue had quietly entered and explored several times, although each time she went further.
But each time she returned empty-handed, except for discovering many fish in the underground river, the largest of which weighed over a hundred pounds and had extremely sharp teeth.
In terms of fierceness as individuals, they could compare to the piranhas Si Miaoxue used to keep in the backyard pond, but to confront an expert at the Meridian Passage Realm like Si Miaoxue was futile.
The section Si Miaoxue explored is estimated to be about three or four kilometers long, which seems quite lengthy.
Actually, with all the twists and turns, the straight-line distance might be just four to five hundred meters, but the general feeling is that it's extending downwards.
Because the underground water level doesn't change.
