The hot air balloon rose at a speed slightly faster than Lin Xian had anticipated, and it was still picking up pace.
With the increase in altitude,
the wind also grew stronger, blowing the helium balloon further from Sky City.
This was the wind direction predicted from the beginning.
The invasion of Sky City was not an operation that could be carried out every day.
Weather and wind direction were crucial.
It didn't matter if the hot air balloon drifted a bit away from Sky City; they just needed to glide horizontally a little longer when the time came.
But if the wind blew the hot air balloon towards Sky City...
they'd likely hit the airspace defense laser zone before reaching a safe altitude, resulting in instant defeat.
Gradually,
Lin Xian sat in the rising hot air balloon, going higher and higher.
The crowd on the ground turned into a tiny bright spot.
The air became cold and biting, with frost beginning to form on the helmet's visor.
