Rule? Isn't It Just a Word Game?

Human resentment has been condensed into rules, and those who enter must abide by them or die. This was the consensus of all the night watchmen until Lin Shen appeared.

Each of the strange copies was cleverly decoded by him - together with them - using word games. But when he fought his way to the end, he discovered: Those enemies hiding in the dark, the lunatics who hunt their own kind... Are just the foreshadowing.
