Qingbo Stockade Exploration Guide

Eavesdrop on the Landbreakers to gather some intel. It seems like you can't fully comprehend the conversation, so you continue to head to Qingbo Stockade.

Continue down the path to get to Qingbo Stockade. At the end of the path, you encounter a closed gate and a wheel that can open it.

Mi Fu spots a supply crate and suggests that it might have something useful. Open the supply crate nearby to get Ferrium Bottles.

Open the Tools bar and select the Jet Drone. Use the Ferrium Bottles to fill the Jet Drone with water. Hold the attack button while aiming at the wheel to open the gate.
How to Spray and Change Water Type

Pass through the gate to finally enter Qingbo Stockade. You begin to think about Tangtang's whereabouts and Ardashir's motives before going further in the area.

After thinking of a plan, follow the path on the water to enter Qingbo Stockade. Head up the stairs to find Stockade residents blocking your path.

Defeat all 4 enemy Stockaders to continue on your path. After defeating them, you begin to interrogate the Stockader, who confesses that they have been working with the Landbreakers.

Mi Fu gathers intel that Tangtang is being held captive. Go deeper into the area to find Tangtang and rescue her. Follow down the path and defeat Stockaders along the way until you reach the stairs at the end.

You need to find a way to rotate the bridge to get to the other side. Roam around the area and try to find the mechanism that can rotate the bridge.
| Find a Way to Rotate the Bridge | |
|---|---|
| 1 | ![]() Head to the right to find Stockaders passed out in cages. Mi Fu tells you about what the Stockaders had gone through in the past that led them to who they are today. |
| 2 | ![]() You can find clues nearby to know more about what happened. There will be a note to your immediate right about a Stockader joining the Landbreakers. |
| 3 | ![]() Follow the path to find a cave where more Stockade residents are trapped. At this point, you will not find the mechanism to rotate the bridge. |

Head up to the cages and rescue the trapped Stockade residents. The residents tell you that they were jumped in the middle of the night and tell you where Tangtang is.

Head south of the cave to continue your search for Tangtang. Another gate blocks your path to Qingbo Stockade.

Equip the Jet Drone tool and use the Ferrium Bottles you got earlier. Spray water on the mechanism in the area to the right of the gate. Opening and entering the gate will complete the mission.
