With Alister's sword wave attack that enveloped the entire Earth, it ignored everything and only attacked the saint-level cyborgs, killing all of the saint-level cyborgs on Earth.
After killing the saint-level cyborgs on Earth, Alister also noticed the monsters who invaded Earth. Although he didn't kill them with his previous sword wave attack, it was due to thinking that it couldn't threaten the humans.
After all, the strongest monster that invaded Earth was just a mere Transcendent Emperor. All of the Monster Saints were already killed by Alister in the dimensional gap.
"Sigh, might as well kill those monsters. Although the human race can defeat them, not all transcendents are as strong as the ones in America. Since I can kill all of these monsters in just a second, no need to let Exoffus and my subordinates interfere."
Muttering those words, Alister decided to kill all of the monsters on Earth as well.
