Just like it's raining—
Countless fireballs splashed down like raindrops, covering the whole of Heaven City!
Those fireballs appear as tiny as raindrops when they're far away, but when they fall, you'll realize their immense size—each fireball has a diameter of about two or three meters, large enough to ignite a small house instantly.
They're evenly distributed over every street, every dwelling of Heaven City—their purpose is very clear, to kill everyone, leaving not a single survivor.
This has gone beyond mere "revenge," showing a noticeable deviation... like a beast venting its anger, biting every animal in the pen without bothering to eat them.
After the fireballs expanded, they didn't explode directly but started to slowly contract back, like a heart... rhythmically gathering the strength needed for the next pulse.
Obviously, a single burst doesn't satisfy Hassan.
