Ten days wasn't short, but it wasn't long either. To Feng Luan who was still frantically hunting the Merman Race, it was obviously too short.
After the news of the Merman Demon Thearch had been killed, the ten battlefronts at the west of the continent had been constantly routed. Whenever Feng Luan made a move, the merman demon kings would be slaughtered. If Feng Luan could appear at this pace, it was a clear sign to the experts of the Merman Race that something had happened to the Merman Demon Thearch. Otherwise, Feng Luan would never leave the Black Phoenix City.
