Neuro re-materializes in the real world, deducing that the sphinxes are data uploaded from supercomputers in the city; when he finds one at a research facility, he destroys it. HAL uses the drug on Higuchi, who helps him create a new electronic drug which works faster but does not last as long. Another sphinx is put on a truck driven by Higuchi. During a chase, Higuchi uses a bridge of people to cross a chasm but Neuro crashes into it.
