How to get hydraulic oil at zero temperature in deep sea trekking

The hydraulic fluid obtained in Deep Sea Trek below zero will swim to the other side of the bridge to wipe out the alien heritage. Don't let go of the gold, silver and copper inside. Pick up three peppers and store them on the sea peppers when they are full. Remember to store two peppers for planting. The broken bridge is next to the Fiji base. After walking over, I found that I needed a hydraulic oil to control the bridge. Scan the damaged hydraulic oil unlocking drawings on the ground, build one at home, bring it over and install it, and then connect the bridge and jump the cup at the control panel.
