The Taiji realm allowed one to teleport, an exceedingly mysterious kind of leap.
The less matter there was in the environments at the two ends of the leap, the easier teleportation became. Conversely, the harder it was, the greater the expenditure.
Thus, in this world, teleportation covered the greatest distance and operated most efficiently in a vacuum.
Teleportation was barely possible within the atmosphere, with the best conditions found at high altitudes where the air was thin.
If one was in the sea, only an immortal might manage short-distance teleportation. The expenditure would be enormous, and the tiny distance was useful only for dodging.
Underground or within high-density fluids, teleportation was completely impossible.
But compared to Earth, the fact that they could teleport at all was already incredible.
Using all their magic power for teleportation, someone in the Taiji realm could teleport five hundred kilometers in a vacuum, while an immortal could cover fifty thousand.
This allowed them to avoid space hazards to a great extent, preventing collisions caused by excessive speed.
Of course, when traveling, they still relied on flight.
In a vacuum, they could only propel themselves by expelling their own magic power, which worked on the same principle as a chemical rocket.
In a vacuum, their maximum speed could reach twenty-five kilometers per second! Since they flew individually and combined that with teleportation, their maneuverability and agility were far beyond anything Earth's spacecraft could match.
However, interstellar travel remained fraught with difficulties. Exploring a single planet often took decades just for the journey.
The reason was that their navigational abilities were far too poor!
The distances between celestial bodies were immense. From "Saturn," the planet beneath their feet, to the nearest "Venus," the third planet, the shortest distance was over forty million kilometers.
At an immortal's speed,
