Pipebomb was quickly racing around through the labyrinthine interior of the vault. Occasionally transforming and tossing out a few mines. From start to finish the process took the better part of an hour.
When he was done he transformed back into vehicle mode and took off. He raced back outside, being sure to pile up a few extra mines around the entrance. He stepped out, making sure to stay a safe distance back. He took a moment to admire the vault as it was, before detonating the well over a hundred mines that lay within.
