The most powerful family in Black Tiger City is undoubtedly the Fang Family.
The Fang Family boasts five old ancestors, plus the previous generation's family head who is currently in seclusion, attempting to break into the Spirit Qi Realm. Their strength is unmatched by any other family.
The strength of the Ye Family is also formidable, only slightly less so than the Fang Family.
Over the years, the Fang and Ye families have been like fire and water, openly and secretly fighting and irreconcilable.
It is very likely that the Ye Family had a hand in the incident with the Fang Family's heirloom medicinal herb.
However, as long as the head of the Ye Family is not a fool, they would certainly leave no evidence for the Fang Family to use against them.
