Genshin Impact has added a secret teleport waypoint in their latest version 4.2 update. Unlocking this hidden waypoint will help you get closer to unlocking the "Font of All Waters (III)" achievement. The unlock criterion is based on activating all the teleport waypoints.

It is worth mentioning that the secret teleport waypoint is locked behind a cave with a blocked entrance. To open the cave, teleport to the waypoint north of Foggy Forest Path and head southeast towards the Rusty Rudder tavern.

Once here, you need to look for an NPC named Permingeat standing near a cannon. Interact with the NPC, who will offer a chance to win some treasure and a key. After a brief dialog, she will ask three questions before activating the cannon to break the rocks from the nearby mountains. Here's a quick overview of the questions and their answers:

• How many tables are there in The Rusty Rudder?
• Answer: Three
• How many employees do we have at The Rusty Rudder?
• Answer: Three
• What is not served in The Rusty Rudder?
• Answer: Romaritime Flower

Delivering the correct answers will finally activate the cannon, which will already be aimed at the boulder you need to break, so just shoot. The hidden cave entrance should be open now, spawning an exquisite chest and the secret teleport waypoint.
