Frankie smiled and vanished off into the tunnels, inserting his hand into his face and pulling out one of Dorian's bullets.  The man seemed to have retreated once Sayuri got down to business.  Frankie applauded his wisdom.  Frankie began to feverishly carve alchemical sigils into the blackened walls of the tunnel, running as quickly as he could to complete the sigils at an inhuman rate.<br/><br/><em>"Two Minutes!"</em>Sayuri called, driving Frankie to work faster.<br/><br/>45 seconds later, the tunnel had the proper lines of force and alchemic sigils drawn into it.  The next part would be the most difficult, Frankie reflected, as he stood at the center of the dark tunnel, holding a depleted uranium bullet in his claw.  As Sayuri began her countdown, Frankie inserted a claw into his chest and ripped himself in half, spilling huge amounts of ichor and mostly digested organs on the walls and floor of the tunnel.  Frankie dissolved into dust as he tore his body to pieces, providing the necessary sacrifice to finish the ritual.<br/><br/>Millions of years of geologic and manmade processes began to work their magic inside the tunnel, transforming residual organic matter first into saturated hydrocarbons, and then further into high explosives.  Meanwhile, the walls of the tunnel flaked off like falling snow, and forged themselves into obsidian knives and steel blades, forming themselves into a rain of flechettes suspended in a medium of nitroglycerin.  The area of packed earth above the ancient sewer cracked and weakend, turning into a barely present lid on the boiling kettle of death Frankie had created.<br/><br/>Through the sacrifice of his body, Frankie transformed a section of the underground into one huge bomb, waiting to give Sayuri a nasty suprise when she went and set it off.  Frankie's spirit retreated into the earth, already looking for components to transform into a new body as he sought cover.  He had no illusions of the bomb being able to kill Sayuri, but with any luck, she would be weakened and forced to retreat, or at least made weak enough for the rest of the DPDS to be able to handle.
