It might take weeks, and he didn't want so much time gone before he found Boss Danzo seeing as he might be in trouble.
Gustav proceeded to scan from building to building one at a time. It was a long and arduous process, but his brain and eyesight were functioning so fast that he only needed to stare at a person for 0.1 seconds to scan their face and figure out if they were what he was looking for or not.
It took over two hours for Gustav to scan this area of the districts. Checking every person within the buildings, streets, and even public roads.
At this time, it was already nightfall but surprisingly, even though the skies were still bright.
Gustav looked up, staring at the star-shaped flaming pearl up in the sky. It was still dazzling with immense flames radiating like an artificial sun in the sky. The light from it prevented the city from entering nightfall like it was supposed to.
