章 990: Different

The Riemannian Echo was a technique to sense gravity that he had created by inserting esoteric substances that were sensitive to gravity and reacted in specific ways to gravity. He inserted them deep into his body so that he would effectively be able to treat them as sense organs inside his body capable of sensing warps in space-time.

That didn't mean that the esoteric substances merged with the cells of his body, or became connected to his nervous system like other sense organs did. No.

It meant that he could sense their reactions to gravity inside his body and thus deduce the curvature of space based on that.

Right now, he was in a bit of a similar situation.

Just like back then, he was definitely unable to sense what he needed to. Considering that he overcame the problem with gravity, there was a chance that he could use the same solution to overcome that problem with the electromagnetic field.
