Indeed, from the very beginning, Xu Feng's intention of using his devastating spells to kill and injure some of them was all for this moment.
There was a limit to how much he could deal with so many players grouping together to siege the city with the monster waves.
Not even Carmen would be able to handle this much pressure despite being a Summoner herself who could summon numerous creatures.
After all, even if one had the stamina and motivation to persevere through, the mana that one player could have wouldn't be able to receive a massive boost.
Even if one had mana reduction or recovery potion, sooner or later, the mana would run out.
And that was precisely the obstacle Xu Feng faced when he was finished using Absolute Undoing, Sanctuary Light, Wrathful Restoration, and Origin's Wrath.
The combination of all these skills consumed most of his mana, which resulted in him having to play a passive yet pretentious role.
