Seven Divine Trees.
Their origin remains unknown, as does the era they hail from.
To most civilizations, when their own civilization emerged, the Seven Divine Trees were already present.
Throughout these eras, it's not that no one has attempted to obtain the Seven Divine Trees, but their strength is never sufficient to make the Seven Divine Trees surrender, or rather, their status is not enough for the Seven Divine Trees to acknowledge them.
And for a divine object like the Seven Divine Trees, even force cannot seize them decisively.
Just as every era has its own supreme treasure, while the power of such treasures is limited, they are indestructible.
Even if a supreme treasure meets its extinction in a short time, as long as the era doesn't end, it has a chance for self-repair and rebirth.
As an existence with a history even older than supreme treasures, the Seven Divine Trees naturally possess this ability.
