The heavenly secret realm was too big and boundless. Without a map, he might really get lost here. Fortunately, Shi Buyu and the other two had given him a map astrolabe. After Xia Pingan left the blood Blade base, he flew for less than two hours and arrived at Mount Heyun.
From a distance, a mountain peak of Heyun mountain in the dark was towering in the Starlight. Its pitch-black outline was like an immortal crane exposing its neck and head in the mist. The entire Heyun mountain covered over 1000 square miles. A faintly, shiny, semi-transparent energy barrier covered the entire Heyun mountain. It was the mountain-protection formation of Heyun mountain. Because of the existence of the formation, the entire Heyun mountain was isolated and covered by the mist. Only a small part of its outline could be seen from the mist.
