The entrance of the Asylum was about a five minutes' walk from the gate, given the speed they moved.
But walking to the entrance was risky, and the only route into the building was an underground tunnel that Sinnett said led into the engine room, which was luckily where Zero was kept.
It would be easier—he and Asher could phase through the walls to get in—and faster, but then, as secure as the place was...
There were infrared cameras, lasers that detected movement, and tiles that, if pressure was applied, would generate energy and alert the soldiers.
Sinnett flipped the lid on the tunnel open and jumped in. Asher asked Nova to go ahead, and he would follow.
Once she was in, he climbed in as well and pulled the lid back over the tunnel. Surprisingly, the tunnels were clean, with passages for water that were also clean, and routes that led to who knew where.
Sinnett, however, led the way to where the engine room was located.
