Chapter 880: The Attraction Behind the Door (Big Chapter, Vote for Monthly Pass)

High Tower Interior

Accompanied by the train racing into the void, He Ao looked up at the ceiling.

The angel hadn't followed him in, suggesting the things inside the High Tower were indeed dangerous.

Ordinary B-level monsters and Transcendents couldn't detect it, but the A-level Angels seemed to acutely sense the difference.

He Ao shifted his gaze, looking ahead of him.

At this moment, he was standing in front of a closed metal door. Opening this door would lead to the High Tower's core control room.

Dried, splattered blood covered the area around the door, a small part of which appeared to be human—likely remnants from the battle during He Ao's last visit. The majority seemed to come from a large monster, probably left by the B-level Great Octopus that had been pursuing him.

Last time he was here, he had used the strength of the B-level Great Octopus to drive away the monster that had "deceived" him into coming, disguised as "Liu Nan."
