LLing Yan stepped into the gray hole. Instead of sinking or floating as he'd expected, he found himself simply entering a vast open space.
The wall Kai had opened was actually a door.
Ling Yan turned and looked behind him. Where the "door" he'd just entered stood a mirror.
As he turned, a figure burst out from the mirror. Ling Yan held out his hands and caught Mu Yuan.
Mu Yuan gasped, steadying himself. He glanced around, collected himself, and let out a few awkward laughs. "So it's a portal? Haha, haha."
Kai emerged from the mirror with an expressionless face. With a wave of his hand, the mirror, standing on the ground, shrank and flew into his hand.
It was a small round mirror, a bit like a woman's makeup mirror, small enough to fit in the palm of your hand.
Kai spun the mirror in his hand and walked towards Ling Yan and Mu Yuan.
