This is just perfect!
No wonder Frank and Lupus never noticed anything odd about the fake pillar produced by the Secret Tower. She had felt it strange at the time and thought the Secret Tower's ability to create fakes was too strong. Turns out, it's because this thing is a half-real, half-fake item.
As a small fragment of the True Spirit Relics, this fake pillar does not possess most of the abilities of a True Spirit Pillar, but people who have never encountered a real pillar can't detect any abnormalities even if they check it.
At this moment, Bai Fu fully understood.
"Just now, Suixi and Elon activated this fragment. It's unclear whether it was to summon an Apostle or for some other purpose, but anyway, they activated the fragment, causing Julia, the main body of the True Spirit Relics, to sense its presence. Then, Julia and I teleported over, which scared Suixi and Elon, and they instinctively asked whether I was an Apostle or an Apostle Follower."
Oh!
