Only Meng Hao could hear the sound of the voice. No one else would have been able to sense even a bit of it. Even though Chu Yuyan was in the volcano along with Meng Hao, she couldn't hear it either.
As the sound filled his head, Meng Hao's eyes filled with an intense look.
"The Ancient Doom Clan... Don't tell me we're in the vicinity of the Ancient Temple of Doom!? The Legacy of the Blood Immortal. An Immortal..." Meng Hao was shocked. He was relatively familiar with all the various levels of Cultivation. After Nascent Soul was Spirit Severing, then Dao Seeking and finally Immortal Ascension.
However, in tens of thousands of years, only seven or eight people had ever succeeded in reaching that stage. Even reaching the Dao Seeking stage was not common.
