Chapter 453: The Unspeakable Existence

"Are you stronger or the existence beneath the River of Life and Death?" Eren asked the author, stopping merely a hundred meters away from the river.

He had felt the existence when he was crossing the river last time. He was even informed by the Cardinal that even the Overlords couldn't return alive if they were to face the existence beneath the sea that was unseen by everyone.

Even his own soul felt slightly restless when he was near the river, letting him feel like he was truly going to die if he even entered the river for a mere fraction of a second.

The only person he knew who could have even a rough idea about the kind of existence hiding beneath was the author who was following him.

"I cannot answer you." The Author was just as vague, as if the existence beneath the river was something he couldn't talk about either. It was also restricted by the rules of this world.
