The subordinate's words were not without merit. If the Sage of the magic beasts died while the Guardian remained alive, humanity would definitely be able to occupy the entire realm.
Even in the worst-case scenario, if they cannot occupy the whole realm, they can still occupy the majority of it.
It can be said that Rezen's Innate Magic is something that can turn the tide of the war as long as he can really corrupt even Senior Beasts.
This matter was important and crucial enough that the Guardian decided to come out of the room where the Tree of Hope is placed to meet Rezen.
In the past, there was a race against time between the Tree of Hope's fruit and the assault of the magic beasts to destroy humanity.
If the Tree of Hope's fruit ripens and a new Great Mage is born before the Guardian dies, the magic beasts will lose. Even if a new Great Mage appeared and the Guardian dies, in the very last, they can maintain the current status quo and barely survive.
