In terms of overall capability, the fleet of the Heaven's Origin Sector did not suffer too many losses in the previous battle. Their formation was not messy, their spiritual shields were solid, and they had sufficient fuel and ammunition.
In regard to experts, it was not that the Heaven's Return Fleet did not have their own Nascent Soul Stage Cultivators, Divinity Transformation Stage Cultivators, and Giant God Soldiers. In fact, their top combat ability was even higher than that of the 'barbarians'.
But in terms of fighting will, or rather, their mysterious 'belief', they were simply 'zero', if not negative, when compared to the crazy outburst of the enemy.
