The elder nodded in satisfaction and said,
"You don't need to be desperate. This water is different from any other; it won't produce man-eating fish or monsters. However, due to the special origin of this water, whether mortals can enter safely also depends on their fate. If one's constitution is incompatible, they will sink upon entering; if it is compatible, they will be unharmed!"
Upon hearing this, the group immediately quieted down, exchanging looks of fear. The elder continued,
"Rest assured, I will cast a spell to bring anyone who sinks to the surface immediately... those who can dive may do so."
After saying this, he took out a porcelain bottle, opened it, and flicked his fingers towards the five of them. Instantly, five medicine pills shot into their mouths,
"This is the Breath-holding Pill that I specifically concocted. After consuming it, you can breathe underwater for an hour. Don't worry about drowning!"
