"Are you sure this is okay!?" Li Huan asked, uncertainty crawling at his skin as he stuck to the ceiling plank like an agitated cat.
"Perfectly certain" Zhao Fang said as he held binoculars.
"Why are we even doing this!?" Li Huan shrieked in the microphone that was attached to the earpiece he was wearing.
"To save the victims? what else!" Zhao Fang gritted his teeth as he continued to look around to make sure Zhang Wei doesn't enter.
"Fuck my life" Li Huan whispered as he slowly tried to reach the vent.
"Did you reach it?" Zhao Fang asked, his eyes moving to find the other.
"Yeah..." Li Huan's voice was heard in the other end.
"Did you open the door?" He asked again and Li Huan once again answered with a 'yeah'.
"Why the fuck is his vocabulary limited at this time?" Zhao Fang wondered before sneakily walking towards the door.
The door creaked open once he gave it a light push.
"It really is open..." Zhao Fang walked inside quietly and started looking for the vent.
