Arrow in the dark

' Then ? ' Claire asked extremely curiously. 

For the first time in her two lives, the divination mana planet in her inner world started stirring. All her spidey senses are tingling. 

' Only the Wulin patriarch returned. He said the fight was brutal. At the end of the fight, they used a forbidden spell, draining themselves, using Wulin patriarch as the conduit. Think of it like an electric shock. Not aimed towards the dragon, but towards the mana source, hoping to shatter it if humans can't use it. They succeeded, but every hunter out there died. Wulin patriarch returned with his body broken beyond recognition. Modern medicine could not have saved him. Fortunately, healers saved him. Otherwise we would never know what happened in the dungeon. ' Song Minah continued. 

' Wait a second there ! You mean grandPa Song did not return with the Wulin patriarch ? ' Claire asked, obviously surprised.
