When i read the chapter, i found that oda is an intelligent writer. He made dof very intelligent. Dof sent "fairies" so that they would steal zoros sword and that too the "treasure of wano" so that both zoro and that samurai would run to get the sword. In the meanwhile luffy hears about the mera mera no mi. Now only swordsman can enter the fight and both swordsman are not there. Neither brook. Now i think that luffy will ask the blind man to win the competition for him or he will go himself with the sword.
This whole shows that oda is good at making storyline. Makes me remember kira of death note.
