18. Feedback Resonator, Cargo Chassis & Cavitation Silencer

Interact with the base NoA to get the Black Box - Singer signal marker. Head toward it.

Tip: Attach a Beacon to the back of the Tadpole for marking routes. Not necessary if you have a good sense of direction.

Pick up Singer’s Black Box at the marker. Next to it is the Mingchan Wreck (Therapy Room), with a small platform nearby.

Go to the leftmost platform first. Scan Tadpole Cargo Chassis 2/3, Thermal Generator, Advanced Battery 1/2. Follow the wire at the platform edge downward.

At the lower level, scan Advanced Battery 2/2. Open the nearby box for Titanium, Copper, Copper Wire, Basic Battery.

Return to the metal wreckage by Singer’s Black Box. Enter the first room — pick up Black Box - Hua Jie and Survival Tool. Turn left to the next room.

In the left room, scan Feedback Resonator 1/2. Use the Repair Tool on the door, enter. Two levels: ground has Modification Station to scan; upper (through lit ceiling hole) has Work Light to scan.

Back at the Singer Black Box location, head N 20 about 200m behind the wreckage. Find a Dive Elevator wire. Upper platform: scan Tadpole Cargo Chassis 3/3, download log data. Medkit and other items nearby.

Follow the elevator wire down. A pink light beside the wire, and another pink light far to the NE.

The pink light marks a Mingchan wreck. Don’t enter yet — drop a Beacon first (need the Feedback Resonator to come back). ~475m from the Angel Comb marker.

On the other side of the wreck, follow an extending wire to the edge. Find a platform with supplies to scan.

From the platform edge, look down to find a cave with glowing silver flowers (appear where silver ore is present). Enter the cave.

At the cave bottom by the silver flowers, scan Feedback Resonator 2/2. Nearby Tail Tribe boxes to scan.

Continue along the rock wall north to find a green area.

North of the yellow-green liquid pool, pick up Black Box - Xi Dama 2. Scan the metal structure 3 times to unlock Metal Farm.

Around Xi Dama 2’s location, the ground has Mineralized Clinker — use the Sonic Resonator to break them for Meteoric Iron. Collect at least 10 — needed later.

From Xi Dama 2, look SW to see a pink light on the upper rock wall. Head up from the pink light.

On the upper rock edge, find a platform. Pick up Cavitation Silencer Recipe and download data. Scan some already-unlocked blueprints. Follow the wire from the platform edge down to scan Tadpole Cargo Chassis.

Warning: Beyond this platform is the map boundary. Crossing it triggers a Shark Leviathan swarm kill.

Return to base. Upgrade the Sonic Resonator to Feedback Resonator at the Modification Station.

Note: Strontium needs to be crafted in the Processor from Celestite.
