The two magic spiders were no bigger than ping pong balls and were transparent, making them hard to spot even in daylight.
They rummaged around by the river for valuable clues, avoiding people when they came across them or hiding in bushes or small holes that were easy to miss.
Finally, a spider found a sewer entrance not far from the river.
Covered by long weeds, the hole of the cave was barely visible. A magic spider accidentally found the place along the river's sand wall.
This sewer was about 1.5 meters high and estimated to be about half a meter wide. There was no sewage coming out of it, so it was more of a secret passage than a sewer.
One magic spider was waiting, while the other immediately rushed over.
After reuniting, the two spiders climbed the rock wall at the same time and began to explore the interior of the sewer.
