The Dao Body was the body of the Connate Cultivator. A Connate Cultivator could live over centuries among the clouds. They could tap into the energy in nature to fuel their body, and their body was able to withstand attacks from even the most powerful weapon of modern-day technology.
Although Chen Fan had not yet reached the Phenomenal Success in his Dao Body cultivation, the Dao Body he cultivated was the powerful Azure Thearch Longevity Body. Even at the Introductory Level, it was already far more powerful than most Dao Bodies at their Initial Success stage.
Even without using his Divine Sense, Chen Fan could feel that his perception of the world around him had changed significantly.
