The wall was not budging under pressure from Renko's fingers. However, her AIES informed her via visual display that she could probably cut through any material around her with her forearm energy blades. From her map display, she could tell that she and Isuzu were in the cargo bay, directly below the bridge.
Meanwhile, Isuzu's AIES helpfully pointed out an access tube to her, again via visual display. The access tube was just beyond a wall in the cargo bay, and could be accessed by cutting through the wall. The tube should lead directly to the Bellystabber's bridge. It would most likely be a very tight fit for them, however.
In addition, her AIES reported that there was an 85% chance that a sizable hole was blown in the hull in the vicinity of the bridge when the ship was destroyed, if she was interested in entering the bridge from outside the ship.
