Inside Xisluo's boundary, the Stargazing Mirror of the Astrology Tower was already adjusted to focus on a certain location Negris suggested.
The boundary blocked out all light around, leaving only the direction the Stargazing Mirror was pointing, reducing various interference of extraneous light and greatly enhancing the clarity of the Stargazing Mirror.
Xisluo fiddled with the Stargazing Mirror, while inside the tower, a Witch was curiously wandering around, observing the distinct equipment of this world and occasionally exclaiming in amazement.
Whenever the Witch exclaimed, Xisluo would turn his head and proudly say, "Just some little gadgets, what do you think? Not bad, right?"
Though feigning humility, his heart was overjoyed. When does a fisherman with a room full of equipment feel the most thrilled?
