The route is short but defended the whole way, so arrive ready for a fight. Once you ring the bell, you have a new rest point on the outside of the tower in the Meigu Lake area.
Where the Pangzhen Sha-Chi Tower Lower Exterior bell is
On the outward side of Pangzhen Sha-Chi Tower, the bell rests on a raised stone shelf. A wooden fence stands beside it, with a pine tree and mist-covered mountains behind.
Start at the Pangzhen Sha-Chi Tower Lower Passage bell; the destination is roughly 200 m away. Hostiles cover the route: a twin-bladed Shadow Warden occupies the walkway by the log pile, while musketeers positioned on and beneath the upper ledge fire at you near the end.
When you ring the bell, “Pangzhen Sha-Chi Tower Lower Exterior” appears on the Meigu Lake area map, and Map Completion rises from 76% to 77%. Resting at the bell opens a menu titled “Pangzhen Sha-Chi Tower Lower Exterior”. Its options are Traverse, Upgrade Equipment, Store, Train Abilities, Save and Leave.
How to reach it from the Lower Passage bell
Make your way to the Pangzhen Sha-Chi Tower Lower Passage bell. Stay beside the red-lit hall until you reach the far end of its floor. From the balcony, locate the wooden staircase leading upward.
Go up the staircase to the top landing. A wooden walkway continues from there.
Continue along the walkway to the logs and planks stacked against the tower wall.
Keep W held and tap Space again and again to climb the logs. It takes three to five hops to get onto the plank floor above.
Cross the top floor to a small wall recess. Turn toward the wall, hold W, then press Space to wall-run onto the higher stone ledge.
Continue along the upper ledge to its far end. One musketeer is stationed about halfway along; another is roughly 6 m from the bell. The one nearer the bell fires straight down the ledge toward you, while two more below aim at its edge.
When you reach the ledge’s endpoint, approach the bell beside the fence. Press E to sound it, adding Pangzhen Sha-Chi Tower Lower Exterior to your map.
