Traveling from the Parasol Tree Domain to the Rainbowfall Domain through the Void Passage took half again as long as traveling to the Violet Thorn Domain at the same speed.
This was not because the Rainbowfall Domain was actually farther away than the Violet Thorn Domain. On the contrary, the actual distance from the Parasol Tree Domain to the Rainbowfall Domain was much shorter than that to the Violet Thorn Domain.
However, different Void Passages shortened distances by different amounts.
According to research conducted over the years, traveling to other great domains through a Void Passage was generally 100 to 300 times faster than flying there across the Boundless Sea.
In other words, different Void Passages had different efficiencies.
The Void Passage from the Parasol Tree Domain to the Violet Thorn Domain was the most efficient of them all.
At the same speed, traveling between the two domains through the Void Passage was a full thousand times faster than flying directly across the Boundless Sea, vastly surpassing the passage efficiency of Void Passages between other great domains.
No one knew why, just as no one knew how these Void Passages had formed.
Back then, in order to allow Qin Huaian and the others to quickly travel from the location of Kun Yuan World to Spirit Rock Island, Senior Turtle had specifically opened a small Void Passage for them.
The appearance of that passage had deeply shocked everyone in the Violet Thorn Great World.
That was because all the Void Passages in the Violet Thorn Great World were ultra-long-distance passages between great domains. The emergence of that Void Passage had shattered the cultivators' understanding at the time.
Yet the Void Passage that had appeared on Spirit Rock Island was merely one within the Chaotic Sea Region, and the distance between its
