This also led Yang Chen to the conclusion that this sound was probably not audible to everyone.
At the very least, a high enough Divine Soul Realm would be required to hear it. His current Divine Soul Realm was probably stronger than that of an ordinary early-stage True God, which was why he was barely able to hear the sound. It was perfectly normal for the cultivators not to hear it.
After all, squad leaders usually dealt with guarding, not patrolling.
What puzzled Yang Chen was that none of the True God Realm squad leaders seemed to have heard the sound, even though there should have been some with extraordinary soul realms.
But why no one had gone to investigate remained a mystery.
As Yang Chen marveled, he knew that he couldn't make a judgment right away, so he put the matter aside for now.
His main concern at the moment was his upcoming battle on the Wind-Thunder Platform against Ming Hao.
Although, to him, this wasn't seen as anything important.
