Get to the Point
From the previous chapter where Dao Ancestor said he let Guang Cheng have a peak at the deduction, he is basically admitting to having manipulated him. To Changshou's face, he said that with a smile, saying 'What can you do?'. Now, its time for the people to pay the piper. Changshou's Dao of Balance demands that every action have a consequence. Kudos to him, keeping his morals even though they make things more difficult for him. That is why is Dao Heart cannot be easily moved or shaken.
