Initially, the Golden Light area extended thousands of kilometers. However, the smaller the Golden Sphere became, the smaller that area did too. By now, half of the Golden Sphere's Energy was gone, and Celis made sure it lost a lot more than it was using with its attacks.
Thanks to that, the Golden Light area had already diminished in size to less than a thousand kilometers, and that's also why Foliana was able to arrive to Kentucky in time to help. Well, if push came to shove, Kentucky would have immediately burnt his Celestial Bloodline to escape that situation, but that would have weakened him by quite a large amount. It was still a very good thing Foliana helped.
There was another good thing about the Golden Light Area becoming smaller. They got to Tanxan and Zangeshu faster!
[Here we are!]
