In the game "Portal Knight", the leap portal of the landlubber has two positions. The first entrance is located near the building by the lake outside the island. The second portal is located underground and needs to be accessed through the dungeon. You can go down from the wellhead next to NPC's residence with a mission axe, walk along the path to the end, and then see a group of people drinking, and go in through the side door to find the portal in the basement.
