After Lin Yuan's comprehension of the space-time domain entered the Seventh Realm, as long as he was within the range of space-time he could sense, he could materialize an incarnation at any location.
The Sixth Realm of space-time allowed Lin Yuan's thoughts to travel instantaneously.
Here, 'instantaneously' still requires time.
Albeit exceedingly brief.
But the Seventh Realm of space-time allows Lin Yuan to descend synchronously.
There is no doubt that this is much stronger than the Sixth Realm of space-time, which requires crossing an actual distance.
There may be obstructions along the way, such as certain perilous space-time terrains that cannot be crossed by space-time travel.
In contrast, the Seventh Realm of space-time is different; no matter how many perilous labyrinths separate the locations, as long as they are still within the range of space-time Lin Yuan can sense, he can descend directly.
