This kind of relatively old residential area was generally semi - Open, including the unit doors of the residential buildings, which were basically open.
Xia ruofei walked straight in. There was no elevator in the old building, so he walked up the stairs until he reached the rooftop.
This building was adjacent to the one where the red signal point was located. The distance between the two buildings was only five or six meters. In addition, there was a protruding fire panel on the roof, so the actual distance was even shorter.
Xia ruofei rubbed his hands and ran to the edge of the rooftop. Then, he jumped up.
He landed lightly on the top floor of the opposite building.
This kind of heat insulation material could not bear much weight. If an ordinary person stepped on it, it would collapse easily. However, Xia ruofei's toes touched it lightly as if it had no weight. Then, he supported himself with one hand and flipped up to the roof.
