Any single one of the four commanders could be an existence that could reign over all parts of the world with absolute ease. Now that the four of them joined forces to gang up against a single human, one could possibly imagine the sheer might of this lineup.
If it were anyone else that had to go against these four, they would most likely be disintegrated into dust immediately, without any room for resistance.
Sealing the Heaven and Earth, all four commanders unleashed their ultimate moves, as their True Skill seeds churned. It was as though the Heaven's Will of the Ancient Saint World was their direct source of energy, with four beams of light shining down from the Heavens onto them, channeling additional power to them consistently.
