Didn't the ancestor of High Heaven Pavilion make a space array near the sect which the sect disciples later used when the central families came to attack them?
@AbCdE321@noore iirc he made it clear that it was unintended, when yang kai was askin him if he knows how to go back there yea? so it was just a fluke from an external artifact n that's the result. i could b wrong, but im kinda sure that's how it went down for the most part.
