With things having developed to this point, Su Xiao wasn't surprised. Blood Gate was, after all, a large Adventure Group, one that dominated the Fourth Tier. There's no way they wouldn't have a few tricks.
Su Xiao glanced at Rin Tohsaka, Illya, and the others in the distance, thinking about which step had gone wrong. Very soon, his gaze settled on Illya.
The chance that A Mu and Rin Tohsaka had been tracked was low, so the problem was most likely on Illya. One possibility was that, before Su Xiao went to the Einzbern family castle, Blood Gate's people had already arrived there ahead of time and planted a coordinate on Illya.
Thinking of this, Su Xiao quickly closed in with Rin Tohsaka and the others. On the way, he put that phone into the Team Storage Space.
Right after linking up with Rin Tohsaka, Su Xiao began sensing whether there was some kind of coordinate on Illya, but he wasn't a perception type, and couldn't detect anything abnormal.
