It was 3-meter tall, green color being and its body was humanoid, and it seemed like it was made of the mire. It had two emerald gemstones in the place of its eyes. Moreover, it was emitting the aura of Empty River Realm!
What made Ace dreadful of this being was it can see through his breathless stealth somehow because he was attacked despite utilizing it to full power just now.
Yet, this wasn't the only bizarre thing because Ace didn't sense this being with his soul sense at all even if it was standing right in front of him. He quickly used his Heavenly Sense and could finally feel this strange being's existence.
But his expression turned instantly ugly because this being was giving off the same feeling as emerald mist like it was a part of it, if not for the strange force coursing through it even Heavenly Sense might've rendered useless.
