Before heading to the rooftop of the side building, they needed to climb a tower about two meters high, because the edges of the tower had jagged bricks for cover, which made them less conspicuous and safer.
Climbing the tower was relatively easy, as there was also a sewer pipe here. Through the sewer pipe, they effortlessly reached the top of the tower.
Once out of the sewer pipe, Angel saw a slightly slanted, elongated narrow path. To thumb-sized characters like them, this was indeed a narrow path, only about two palms wide. Its purpose was to collect rainwater and sewage to prevent seepage into the floor.
"Just follow this path all the way, and you'll reach the side building. The most important thing is, this path completely avoids the surveillance range of the puppet guards. They would never think that this path is passable," Cha Cha the Rabbit boasted as he walked, explaining how he discovered this path.
