Hunter x Hunter - Season 1 Episode 12 : Last x Test Of x Resolve! 2014

The team stays inside a small room for fifty hours and keep themselves from getting bored. Then they spend the remaining time going to a series of traps and tricks. At the last room, they encountered two doors and are forced to either choose the long and hard path (45 hours) in which all of them may use or the shortcut (about 3 minutes) wherein two of them must be left behind. As disputes break out among them, Gon comes up with an ingenious idea of opening the long way and breaking through the wall to go to the shortcut so all five of them pass this phase.
