"A pit?"
The guard politely explained, "On the west side of Marketplace Island, a row of large pits has been dug. When the Spiritual Energy Tides come, many people hide inside them and use Magical Treasures to set up barriers to withstand the tides. Although the force of the tide still affects the pits, its power is greatly reduced."
Lin Chen suddenly realized, "So during the Spiritual Energy Tides, does everyone hide in these pits?"
The guard replied, "The pits are limited, and not everyone can hide inside."
"Why not dig more pits then?"
Lin Chen said this subconsciously, but upon seeing the guard's strange expression on his face, he suddenly grasped something and widened his eyes, "Are you not allowed to dig at will?"
The guard answered, "The island is only so big. If everyone starts digging willy-nilly, I'm afraid the island would be hollowed out in no time. Besides, if everyone dug pits, how would the businesses on the island continue to operate?"
Lin Chen understood.
