Philip to the Kali empire
After handing over Arc to the Old beast, Sam returned. Of course, the Old beast easily agreed to train him.
Arc is quite talented as he reached Level-6 transcendent stage with the limited resources he had. In fact, from what Sam knew there is no specific lineage of Transcendent stage cultivators in the empire. Arian family, the imperial family is trying to create a lineage, until it is established, they will have to face the Transcendent cultivation as an unknown thing and face it all by themselves.
But now, things are going to change.
Arc for the first time after he reached the Transcendent stage is going to receive guidance. He is a lightning elemental user, Old Beast is a Raiju who is at an extremely high cultivation level.
From what Sam knew and heard from Yanwu, the Raiju clan should be in the same realm as the Golden Sun crow clan. But Yanwu doesn't know much about them as their territories are too distant.
