The moment Evan entered the portal, he felt his body sinking rapidly as if he had jumped into a muddy swamp, and his vision turned black.
Evan had entered portals many times before, so he didn't panic because of the sudden blindness and waited patiently.
Within a few seconds, his vision recovered, and he found himself drifting forward in a narrow void tunnel. Some distance away, he noticed Velgoth, who looked like a dead fish, struggling to maintain his balance as the void tunnel moved rapidly around him.
Because all of Velgoth's powers were sealed by Evan before he threw him into the World Passage, Velgoth still hadn't recovered from the blindness, and his fragile body was slowly being corroded by the powerful void energy that filled the tunnel.
Although Evan saw that Velgoth's condition wasn't good, he didn't unseal his powers, fearing that the void tunnel wouldn't be able to withstand the pressure of a Rank Five Core Evolver.
