Chương 499: A Bell

"Bagu Cave Master, behind you..." Holy Ancestor's voice betrayed his horror.

"Behind me?" Bagu Cave Master was confused. Yet, at the same time, he sensed someone breathing lightly behind him. The person was directly behind him, and he could tell they were within a half meter from him.

"When did this person arrive?" Bagu Cave Master's heart began to beat erratically.

He was a supreme expert above the Cloud Realm. In terms of battle strength, he was confident that he could rank in the top 2 among the experts currently here and was just a little weaker than Sword Ancestor.

Therefore, he could not believe that someone had approached him from behind and come so close without being noticed.

"How is this possible?"

Bagu Cave Master was terrified.

As were the Three Ancestors, Blood Bladesman, and Dong Ming King.

They all watched the person standing behind Bagu Cave Master intensely.
