Although its appearance is somewhat different, it indeed bears quite a resemblance to the yam in my memory, even the smell seems almost the same.
"Is it a food similar to yam?"
Weighing the round tuber in his claw, Austin pondered silently in his heart.
This world is vastly different from the environment of his past life, so naturally, the types of food can't be exactly the same. However, these ordinary foods have at least one or two similarities, though the reason is unknown.
But these matters don't have much to do with Austin, anyway. Questions like why he traversed worlds are impossible for him to solve no matter how hard he thinks.
Currently, what's more important is the significance of the "yam".
