Capítulo 693: 221. Seize the spring water? _3

Noland Lee's thoughts wavered, and he cast a "Mind Beacon" towards the nearby sea island of Island 102353.

"Changing perspectives, if I were Fagen, where would I station my spy to watch?"

While using "Mind Vision" to achieve vision leaps, Noland Lee was thinking quickly.

The sea island map obtained from Kaiden's deconstruction appeared in Noland's mind.

He compared the distribution of the islands to the Demon Brain Parasite's cave as the center, drawing a circle with a radius of 40 kilometers.

In this circular area, anyone could observe the surroundings of the cave occupied by the Demon Brain Parasite using their naked eye + telescope combination.

If this circular area was extended by one or two hundred kilometers, people in that range could no longer see Island 102353. They would have to rely on extraordinary means to observe the surroundings of the cave where the Demon Brain Parasite resided.
