After learning that this man actually worked for the duke Moronto family, Grace did not kill him. As an A rank powerhouse, he was definitely valuable and could be used as a negotiation tool with the duke. So he was knocked unconscious and was bound up thoroughly with a magic item. After that everyone increased their pace of the journey a little bit as everyone was interested in knowing what had actually happened with Costogolomo, Goblet of Winter's End and the Moronto family. So everyone wanted to reach the city of Moronto as soon as possible.
So in just two more days, Elena's gang were able to see the city at the distance. Utreyana was a large city but the city of Moronto was even larger. But still to an outsider like Tomoe, the city of Utreyana still looked more majestic and obviously the reason for that was the existence of the temple of pride.
