The pure white glow receded like a tide, and the illusion of weightlessness and sensory deprivation was quickly replaced by an unprecedented sense of fullness.

Perception was the first to return.

As if suddenly diving from thin air into the deep sea, elemental energy of all kinds, so dense it almost turned into substance, instantly enveloped everyone in the train car like warm, heavy seawater.

This concentration far exceeded any terrain Outside the Realm; according to everyone's perception, the elemental concentration here was nearly ten times higher or even more than that of the outside.

With every breath, what was inhaled was no longer simple air.

Instead, it was a surging and active flow of energy, making even Bai Cheng, who had just broken through, feel her meridians swell slightly, while Yu Nian couldn't help but let out a low cry.

"Is this... the Infinite Realm?" Yu Nian looked around the interior of the train car, seemingly trying to find some difference, but aside from the ubiquitous, dense elements, the train itself remained unchanged.
