The iron clanged on the door, and a quiet passage appeared before him, identical to the one he'd travelled before.
But out of caution, he still took a glance at the back of the iron door, the side through which he had entered.
There, he saw an iron plate hanging silently as if it had not been the source of the clanging noise just moments ago.
Rust-eaten secret marks were engraved on the plate, inscribed with a proverb from the "Iron Law of the Night Watchman": "The Tower of No Bell, effulgent Netherworld Light, whose mighty sound reverberates across the nine seas and the vast wilds."
Lin Yi reached out to touch the iron plate.
"Ding..."
A familiar taste, a familiar recipe, and in his mind, as if a transition CG was playing, emerged the slender figure hammering a tool, and then the figure quickly vanished.
"The taste is right... I'm on the correct path!"
Lin Yi stepped through the iron door without hesitation.
