Mu You had assumed that a lake in a depression like this was not connected to any rivers outside.
But when he examined the map closely now, he discovered that a small branch of an underground river did, in fact, connect to the lake from beneath the ground through a winding Underwater Passage.
That gave him two routes to the place where Froglet was trapped: fight his way straight there overland, or sneak in through this Underwater Passage.
The overland route was out of the question. The lake was too close to the Imperial Capital, so the surrounding area was bound to be heavily guarded. Fighting his way straight in would be walking to his death. Besides, making such a commotion would easily alert the enemy.
Mu You had originally planned to wait until they destroyed the tower and the guards surrounding the lake withdrew before seizing the opportunity to rescue Froglet. Now that he had discovered this underground passage, however, he could go take a look ahead of time.
With that in mind, Mu You immediately adjusted the Ghost Ship's course, making a place called Plum Blossom Town its first stop before heading to the capital.
It was still nearly a day's journey from there to the capital, but from beneath that location, he could reach the entrance to the Underwater Passage on the map by the shortest route.
