Destruction

On the nearby mountain peak opposite the World Tree Nordrassil, Malfurion finally heaved a sigh of relief after seeing Archimonde die.

In fact, all he did was awaken the ancient souls through the ritual and the Horn of Cenarius. The horn didn't have the ability to command the ancient souls.

So in fact, the attacks launched by the ancient souls against Archimonde were all Nordrassil's own actions. It had guided the souls to attack Archimonde only to protect itself.

Moreover, it was actually impossible to kill Archimonde with just the self-destruction of the ancient souls alone. Among the attacks was the energy that Nordrassil had transmitted to Archimonde.

Nordrassil was rooted in the second Well of Eternity, so its existence was a powerful magic network node that could transmit a massive amount of magic power energy.
