After entering the city, Aizen didn't go directly to Viggo's residence but instead headed to his room at a certain inn.
He knew that Viggo would undoubtedly learn of his return immediately. The entire city was practically filled with the Heavenly Demon Clan's informants.
These informants weren't just disciples of the Heavenly Demon Clan but also members of its subordinate faction, the Heavens and Earth Society.
There was a Heavens and Earth Society branch in Triesenberg city, and within the city, one could occasionally spot some loafers wearing black clothes and hemp shoes. These were members of the Heavens and Earth Society.
These thugs had no remarkable Sorcery skills, but they were numerous.
As local bullies, they collected protection fees under the Heavens and Earth Society's orders and wandered around gathering intelligence through idle chatter.
The authorities generally turned a blind eye to their activities.
