To complete Stone's quest in Sunken City Underground, you'll need to start at the Living Pod area. The quest involves helping him find his friend Hubert, and it also requires you to find a Nutrition Cube. This guide explains how you will be able to retrieve it.

Before you start, you'll want to keep your gear that provides you with poison resistance or carry antidotes for protection. Locate Hubert and provide him with the requested items - 3 Mud Balls and 1 Salted Mud Ball. Interact repeatedly with all items to get them delivered.

Next, you need to feed Hubert the nutrition cube. After fulfilling his request, he'll then reward you with an item in return. Proceed by retrieving their nutrition cube that appears as a purple item; use the elevator to reach the area where the Nutrition Cube is located. There are enemies in the area, so you will need to explore carefully.

Once you get your hands on the cube, return to Hubert and give it to him. You'll need to carefully navigate through the spikes to stone and interact with him to retrieve another item, which in return completes the quest.

Completing this quest also unlocks the "Friends United" achievement, and it marks the end of Stone's story arc in AI Limit.
