This was an unfinished building, with nothing but cement floors, and without windows or doors installed, let alone elevators.
Wang Mengyi led the way, with Han Jiaojiao and Tian Xinyue in the middle, and Wei Jie bringing up the rear. The four of them were continuously climbing upward.
When they reached around the eleventh floor, Tian Xinyue's legs gave out, and she stumbled onto the cement steps!
"Xinyue!" Han Jiaojiao quickly grabbed her to prevent her from falling.
Drenched in sweat, Tian Xinyue almost breathlessly said, "Jiaojiao, I can't go on…"
Han Jiaojiao was also exhausted, and the two boys had been tired for quite some time. They had run all the way here, and after entering the building, they had hardly rested before starting to climb the stairs. The physical exertion was immense, and now both were gasping for air and couldn't talk much.
