Zhang Yu glanced at the patch of golden light and immediately understood. This was likely an array artifact, meant to carve out a separate expanse of space for them to fight in.
This was because the commotion caused by Upper Layer cultivators clashing was simply too great. Especially for those who had attained superior fruition—when their magical power and Heartlight Seal were fully unleashed, the aftershocks shattering stars and obliterating suns and moons were nothing unusual. Ordinary lands could not withstand it, whereas fighting within a separately opened expanse of space left them free of all such concerns.
There were such places in Celestial Xia as well. For instance, he had sparred with Long Yi within the Prison of Suppression.
He rose from his seat and walked over, coming to a stop atop the golden light. Cai Li smiled at him, then felt his body sink slightly. The two of them slowly sank into that pool of golden light. His expression remained utterly calm, and in just a few breaths, the golden light swallowed them both.
When Zhang Yu looked up, he found himself standing upon a boundless stretch of land. High in the sky hung a pale white Earth Star, half-illusory and half-real, almost pressed against the side of the Earth Continent. Its immense outline resembled a broken wall on the distant horizon.
Cai Li said, "This is the Forgotten Star Domain, an array treasure of my clan. Though it may look rather strange, it is in fact no different from the outside world. Here, Zhang True Person, you may use whatever methods you wish. Even if you smash this place to pieces, I need only refine it a little afterward to restore it whole. So you need not hold back—just attack as you please." A trace of excitement
