Recalling all the previous encounters, the most likely thing that could have left a trace on him is this ring.
Looking back at the scene where the Red-clothed Woman suddenly presented the token of affection, it does seem suspicious.
However, he had doubts before and had carefully inspected this ring, finding it was just a pure ring, with no hidden craftsmanship inside. If it truly serves as a tracker, how does it work?
Moreover, why did they locate him repeatedly without taking any further action?
Could it be that there was no malice?
Could it just be that woman's pure desire to control?
Or does she know his identity and wants to figure out his every move?
But all these are his imaginations, everything is out of his suspicion, and he can't even be sure if it's definitely this ring that's problematic.
So, overthinking is useless; the most urgent thing in the current situation is to determine if this ring is the problem.
