In Lingyun's Illusory Realm, one could conceal a sudden surge in fortune without worrying about startling the guardian slaves. Tang Ye's signal for Lingyun to play music and construct the Illusory Realm was a matter that had already been discussed. His plan was to first discern the enemy's foundation and then launch a surprise attack to annihilate the enemy in one fell swoop.
The strategy of the chess-crazed was to generate a chessboard and then control the game from outside to kill the enemy. After Tang Ye had figured out his ability, and seeing the chess-crazed person fall into a state of self-perceived confidence, he knew the time had come, so he signaled Lingyun to begin playing.
