Bone Grand Authority, Bone Control.
As long as he continued expending divinity, he could restrain any target with bones indefinitely.
In theory, Qin Feng used the power of the Bone Grand Authority to control the bones inside the target's body. If its bones could not move, naturally, its entire body could not move either.
Unless the target could instantly pull out every bone in its body and discard them...
At that moment, because the dark element flying dragon's attributes were extremely high, the ongoing divinity cost of using Bone Control on it was also considerable.
Qin Feng spent over 220,000 divinity, yet could only restrain it for 0.01 seconds.
But those 0.01 seconds were already enough for Qin Feng!
As long as he could touch his opponent...
Instant Annihilation!
Since his combo points would be fully refunded, effectively never being consumed, Qin Feng had already accumulated over twenty-seven million combo points, enough to increase Instant Annihilation's damage by 270,000 times!
This special effect came from the Cursed Slate of Illusory Dream God Lutas, effectively forcing Qin Feng's maximum damage up by several orders of magnitude.
Of course, the fundamental reason was that, after evolving, Qin Feng's Void Lock skill allowed his combo points to stack infinitely without an upper limit...
When the dark element flying dragon was restrained for 0.01 seconds by the grand authority ability, Bone Control...
Qin Feng flashed over with Space-Shattering Shadow Kill.
Once again, a single strike of Instant Annihilation, plain and simple!
The dark element flying dragon, whose health had also increased by over 390,000 times, still had its health bar emptied in an instant!
With that, all nine elemental flying dragons had been slain!
As the system notification announcing the completion of the challenge arrived...
The nine elemental flying dragons' health bars were restored.
