With the death of the Spear Hero, Shield Hero, and Sword Hero, all of the six invading heroes were finally eliminated.
When Alister had used his Movement Petrification (Gold) talent, the petrification of those three heroes' movement allowed Zanna and Ignis to seize the opportunity of killing the three heroes.
Not only were their movements petrified, but their mana and abilities were negated by Alister's negation superpower. If not for Alister's abilities and simulated talents that could surpass the six heroes' hero authority, it would have taken a lot much longer for them to defeat the heroes.
With the defeat of the six heroes, the greater spirits and advanced spirits started restoring the spirit realm.
Since they had successfully defended the spirit realm, all that was left was to deal with the aftermath of the war.
