The fact that the Devil Clans had conquered half of the Upper Province of the Dao Martial Saint Land was a testament to their extraordinary strength. Moreover, there were many Bodiless Celestials in the Devil Clans as well, and some of them had remained in the Land of Exile. However, more and more Bodiless Celestials began to leave the Land of Exile to join their respective clan in the Dao Martial Saint Land. The devils Duan Ling Tian had encountered when he was in the Lower Province previously were nothing compared to these Bodiless Celestials.
With the Bodiless Celestials presence in the Devil Clans, the various clans' management, naturally, improved. There was less infighting among the Devil Clans. They were now united against the people of the Dao Martial Saint Land. With that, how could the Devil Clans not be strong? It was not an exaggeration to say they were as tough as an iron board now.
