Li Ang looked down at the glass cylinder on his left shoulder, known as a battery. The contents of the cylinder must be some kind of energy liquid that can charge this suit, allowing it to alleviate my shock symptoms. Or it's also some kind of drug, part of which is delivered directly into my body to relieve shock.
Li Ang thought about it and tried to pry the glass cylinder. It's fixed on top; it can't be pulled or twisted off. If I force it, I might shatter the glass cylinder. This thing is a battery; I'd better not mess with it. I'll also have to be careful not to break it when I move later.
He stepped up to the metal door and tried to twist the L-shaped doorknob, but it wouldn't budge.
He kicked the door lightly, and the dull thud that resulted was proof enough that this door couldn't be broken by human strength.
This thick? A vault door?
