Suspended Mountain Secret Realm.
When the fourth Heaven and Earth Dao Sound rang out, everyone stopped their actions and silently listened.
The Dao Sound was vast and boundless, echoing through the eight directions of heaven and earth, and even the secret realm could not stop it.
It wasn't until the Dao Sound faded and ceased to ring that everyone came back to their senses, causing a stir of commotion.
"The fourth Heaven and Earth Dao Sound, it has come so quickly?"
"I can feel it, the concentration of Spiritual Energy within the secret realm is increasing!"
"The fourth Heaven and Earth Dao Sound signifies that the Heaven and Earth Rules of the outside world are evolving to become even more perfect!"
...
People in the secret realm discussed animatedly.
Inside the ancient temple at the summit of Suspended Mountain.
Several powerful Wills were also in the midst of a discussion.
