Grey Tree

Ace didn't dare to believe what he just felt so he hurriedly circulate his HD-Qi with the help of Dark Void to confirm what had just happened.

But to his disappointment, the Dark Void was tranquil and he didn't have any kind of strange feeling like before. It was like that feeling was just an illusion.

However, Ace's senses were never wrong before especially after he formed the Yellow Soul Core of the black wind soul. Therefore, the feeling he felt before was definitely real. But the question was just what happened and why isn't the Dark Void reacting anymore?

Ace finally made up his mind as he saw that gloomy grey trees forest. He's going for hook or crook this time.

Since there weren't any leaves on those grey trees the gaps between them seem like dark roads or mazes. No one knows where these roads lead to because there was not a single record about this kind of tree in the books that Ace possessed. But Ace was about to find out soon.
