Cha Na hurried up to the third floor, barely rounding the staircase corner when a violent explosion erupted behind him, debris and shrapnel scattering like shots from a shotgun.
Half of the ceiling on the third level had collapsed, and torrential rain poured over him, the dense curtain of water pressing down like a quilt, bending the boy so he couldn't straighten his back.
A beam of flashlight shone up from below, and on the square, a soldier still left on lookout caught Cha Na in the light before a volley of 7.62mm caliber bullets flew towards him.
Cha Na promptly threw himself to the ground, then, rolling to the side, he crawled deeper into the floor.
Bullets shattered other parts of the ruins, cascading down with the rainwater onto his back as the water streamed through the holes in the collapsed floor to the second level, forming a small waterfall.
