I think my favorites are； 1. Early in the show when Lee Ui Bang breaks into the first Emperor's room and is like "Emperor, consider yourself deposed!" 2. Lee Ui Bang's death 3. Jeong Gyun's final battle with Gyeong Dae Seung + his death 4. Gyeong Dae Seung's post-death scene where he walks down the aisle with Mang Yi (but his girlfriend got relegated to the crowds?) 5. Archfiend's death
There was a dream scene where Gyeong Dae Seung woke up feeling lost and alone, but it got cut in the version I watched, I had to find the original scene on YouTube.
