In the eyes of the Wither-Bloom Venerable, the Mo Family Four Brothers were indeed more powerful than them, but that didn't mean they could truly become the protagonists of this Realm.
The real protagonists between Heaven and Earth were True Immortals, and in the absence of True Immortals, there are still several Supreme Strong ones in the Realm, hailing from Independent Practitioners or the Immortal Gate Powers. Each of these powerhouses holds a pivotal status.
Here, they might not necessarily become the protagonist.
Only those supported by True Immortals and carrying forth the will of True Immortals had the qualifications to become the protagonist on the stage of this Realm, and only they had the right to decide the direction of the future.
