Cell 5 'Death Surveillance' seems to follow the mechanism of the 'Lifting Game'.
According to the original rules of the 'Lifting Game', this game is very safe. At that time, Chan Ran played quite well, just getting pinched a few times, with the biggest negative impact being that he might have trouble holding a fineliner pen steadily.
But in this game, it's no longer 'surveillance' but 'Death Surveillance', and the punishment has changed from whipping to a nail gun.
The nail gun was a tool that appeared in the 'King's Judgment', and its power is actually greater than that of a real nail gun. If it hits a vital area, it's almost a sure kill.
Literally, cell 5 is the most dangerous.
As for cell 6, it seems somewhat ambiguous in meaning.
Upon entering this cell, there are two choices: The first choice is to randomly select a cell from other cells, but it's very possible to pick the dangerous cells 4 or 5.
