"The door might need some handling."
Qian Cangyi stood by the door and glanced at the door on the left side, worrying that once he went inside, the door might shut. So, he activated the leader to the Time Tomb gang, then rushed to the desk in one second, spending double the time dragging the desk to the door to block it, and then ended the skill.
Although doing this might lead to the situation where ghosts outside prevent the door from closing, with the skill as a holed card, it's completely acceptable. Instead, having the door close during an investigation could result in being unable to react in time. Moreover, even with the desk blocking it, the door might still be forced shut; however, if that's the case, it indicates that it's impossible to prevent the door from closing by normal means.
