As for going further...
To ensure that nothing unexpected happened, it was best to find out what the source of the shady line was.
As he thought about it, Fang Heng focused his gaze on the crack under the great holy sword.
The strength that could freeze souls came from this crack.
Affected by the frost aura, the scattered Bones around the crack were covered in a thin layer of frost.
Bones!
Right, the City Lord's ancestor, the frost-white Bones, lived not far from the great holy sword.
Through Kou Ming, Fang Heng knew that the Federation had already found a way to open the secret passage to Frost Hell ahead of time.
At that time, he could leave through the secret passage.
When he leaves, he could take the Bones with him and complete the mission to find the ancestor's corpse issued by the owner of the Frost Fortress.
Fang Heng had a hunch that this mission might be related to the secret of the source of the shady line.
