Ada pondered for a moment, then continued, "There, there exists a substance known as 'Water of the Netherworld', something almost extinct in this world. Drinking it can refine your heart and open up your senses. Of course, the chance of it happening is slim; the fewer senses you have initially opened, the more significant the effect and the higher the probability of success. For someone like you, who already has five senses open, it would have almost no effect. However, it's not guaranteed. If you're lucky, you might even be able to fully unlock all seven senses with this Water of the Netherworld, although the chances of that happening are, at best, one in ten thousand."
Ada casually smiled: "I had a premonition of all these details when I entered the fifth phase. I know the approximate location, but as to the specific conditions, we will only be able to know upon arriving at the location."
