The Spirit Desert Civilization's interworld teleportation technology was something known as the Storm Eye.
These Storm Eyes looked like endlessly raging tornadoes, with countless black grains of sand swirling within them.
Seeing past the surface, Richard could tell that the essence of this storm was the same as a Wizard Dimension's Teleportation Gate. Both created spatial singularities, entangled them, and thereby opened a passage between two worlds.
However, compared to Wizard Dimension technology, Sand Spirit technology was somewhat more primitive.
Richard and Sha Mantian arrived at the Storm Eye. Although Richard could travel through the Endless Dimensions, before the alliance was formed, the Sand Spirits were unwilling to reveal the coordinates of their home world.
Thus, Richard could only take the cross-domain passage, traveling through one world after another.
Once they entered the storm, the expected battering of sand never came—the grains were merely projections from the inner Curtain and had no effect whatsoever on the outer Curtain.
The gale howled beside Richard's ears, yet the sound seemed distant, as though it came from another world.
Amid the howling wind, Richard suddenly felt the world around him spin. A powerful suction force abruptly wrapped around his body, as if he were inside a straw while someone with astonishing lung capacity was drawing in breath from the other end.
Buzz!
A humming sound rang beside Richard's ears.
This was not tinnitus. It was the energy around him resonating.
The next moment, Richard entered a pitch-black passage like a pearl in bubble tea.
But the suction did not vanish. It carried Richard along, propelling him rapidly toward the other end of the passage.
"What is this? A boost?"
Richard spoke to Sha Mantian beside him.
Sha Mantian had the appearance of a strange creature with a wolf's head and a human body.
