The origin power was hidden in the mysterious ice rod. It hadn't been released before, and it only exploded when the rod collided with Ye Wu's combat sword.
The origin Energy had ignited a trace of the mysterious ice Rod's power, causing its power to surge.
The mysterious ice rod was one of the best origin-level divine weapons. Lu Ming and the rest could not unleash the true power of the origin-level divine weapon at all. They could only activate a tiny bit of the weapon.
Origin-grade weapons contained the mark of origin. Only those at the origin realm could truly unleash its power.
This was because existences at the origin realm could control the power of origin.
As for Lu Ming, the origin Energy he controlled was too weak. He could only activate a trace of the mysterious ice Rod's power, but it was enough.
