The moment Ace activated his ability, both of them vanished as the trees managed to grab nothing but empty air.
With Ace's current strength, it was easy to escape these trees that seemed to have only instincts; they were no real threat as long as someone knew how to avoid them.
The next moment, they both appeared far above the black forest under the neon sky and continued to rise above. Only now did Ace sense a powerful restriction of laws the higher he got, so he quickly stopped.
Eva's eyes shone as she looked at the forest below, and she smiled, "Good work. I was about to obliterate them."
Then she hesitated before she told Ace through the voice transmission, "I think those trees are abyssal beings."
Ace was surprised, "Are you sure?"
"I'm 80% sure. It is a secret realm that belonged to one of the rulers of the abyss, after all. So, it isn't a big deal for them to have beings of the abyss. We should be more careful." Eva gravely stated.
"Just what is this abyss?" Ace couldn't help but ask as he became increasingly curious about the abyss.
Eva hesitated momentarily before gritting her teeth and revealing, "Since you can already understand the forsaken language of the abyss, it won't be a big deal to tell you. Within my inherited memories, I found vague knowledge about the Nine Everlasting Heavens and Ten Eternal Abysses!
"The Heavens and Abysses are two sides of the same coin. This means that each Heaven has a corresponding Abyss, the only difference being that Heaven exists above while the Abyss is below. Both sides have their own rules and laws. Most importantly, their own races and inheritances.
Ace hugged her back as he gently said, "Don't worry about it too much. You did well telling me about this information. Now I won't be in the dark and know my goal."
Ace's eyes shimmered coldly, 'For each heaven, there is a corresponding abyss, huh? But there are only nine heavens, while the abysses are ten. Does this mean the abysses are more powerful than the heavens? Then there is the system, the enemy of Heaven, while I don't know what stance the system had for the abysses.
'Tsk, what a headache. I'm still a slightly bigger ant in the grand scheme of things; I need the power to survive and protect those who are dear to me. I don't want to end up like the previous heaven's stealers...'
Ace's eyes were filled with complex emotions as he got some clues about his end goal or at least what needed to be done so he would not end up dead.
"Alright, let's go. We need to find the trial or whatever is hidden in this place. I have a feeling that this place might have more mysteries related to the abysses." Ace solemnly stated before he flew in the direction where his thief sense was pointing him with Eva.
The black forest was massive; it had no end, even after flying for half a day.
However, after a few more hours, Ace suddenly stopped as his eyes went wide when he looked far ahead. Eva also sensed something as she looked in the same direction, and her eyes widened.
A few miles away from their position, they finally saw the end of this grand forest; however, what they saw, they weren't expecting it at all.
Because there was an endless blackness like space, and just looking at it, a chill went down both of their spines.
With trepidation, Ace couldn't help but ask Eva, "That isn't the entrance of this heaven's corresponding abyss, right?"
