It's actually the Heart of Thunder Flame Stone!
At this moment, the people outside of Thunderflame Valley who saw this scene were all shocked, completely not expecting such a sight!
It's rumored that the Heart of Thunder Flame Stone only appears once in many years!
It's the countless collisions of thunder and flame, coupled with the shroud of cosmic energy, that can make the Heart of Thunder Flame Stone appear!
That is the purest form of the Heart of Thunder Flame Stone, everyone knows that this thing is a treasure.
Once absorbed, in the future, even becoming the Demon Palace Master might be possible.
No one had seen the previous Demon Palace Master, but everyone knew that he used to be a weak person who became strong after absorbing the Heart of Thunder Flame Stone, eventually becoming the Demon Palace Master!
But the Heart of Thunder Flame Stone is not so easily absorbed, yet it represents a great opportunity!
