Advisor: Sire, sire! A great artist has appeared in the capital! His works have completed the Great Wall!
Me: Wonderful! ... Wait... we already had the plans. Did he draw better plans?
A: No...
M: Did he teach us more efficient building techniques?
A: No.
M: What did he do, then?
A: His great painting inspired the citizens, whipping the building blocks together faster!
K: They hurried, then? Did they allow the mortar to harden? Could they easily have made mistakes? How did they shape the stone faster? Could the fast shaping have chipped a brick? How do you know this wall will even hold?
A: Uh...
M: GUARDS!!!
