All of this was listed on the first jade token Tang Yin bought.
The content on the second jade token talked about Blue Pearl City. Blue Pearl City was owned by a powerful sect in the south zone called Deep Pearl Sect. The Deep Pearl sect was a Rank 3 Organization with a peak Qi Transformation Realm cultivator in charge.
The Deep Pearl Sect also supposedly housed one more Qi Transformation Realm cultivator. But this was just a rumour, nobody knew if it was true.
The Deep Pearl Sect owned 3 cities, one of them was Blue Pearl City. A peak Spirit Vein Condensation Realm cultivator was a City Lord of each city, including Blue Pearl City.
The third jade token Tang Yin had bought talked about any recent events which had taken place in the south zone. Tang Yin brought this jade token because it was cheap and would provide him with enough information about his surroundings.
