Chapter 860: A Heavenly Oath

Ace felt the terrifying auras, not just one but too many, and he never felt that sort of ghastly ambiance before. Furthermore, there was boundless killing intent emitting from these auras as if they wanted to kill everything in their path. 

Ace's heart palpitated when he suddenly sensed an extremely familiar soul signature within those auras. 

Even though it was weak, Ace would never forget the soul signature of the giant demon who forced him into the space tear in the demon continent, and he ended up in the Regal Fiend Tower!

'But it doesn't make sense! Isn't that guy supposed to be on the voyage to subdue the White Crown with the Devil Race, humans, and the Blood Ancestor forces? Just what in the world is happening? How can he be here and closer to the Union Leader, no less!' Ace's mind raced as the more thought, the more complex it all became.
