Kai walked through the tunnels and went straight to the library. He had used that path once, which was when he ran away from the guards, but it was still fresh in his mind, and it wasn't that hard to find it either.
The chimera was nowhere to be seen, which was a good thing. Kai still needed to find a way to deal with that creature if he ever found it down there. This time, he didn't have Luke to help him.
There was a lever in the tunnel walls, and when Kai pulled it, the passage to the library opened before him. He stepped inside the library, and the passage closed right after.
'I just hope the alarm is turned off or something…' thought Kai.
The alarm was something that concerned him, but he wasn't too worried about it. If things went wrong, then he would just return to the train anyway.
