The secret technique of Disappeared Dimension was a small circle on the Secret Technique Wall.
spatial sub-origin was hidden within the circle, and the secret technique was profound.
Below it was a brief explanation.
This was a life-saving secret technique.
With the progressive path of space "dimensional crack" as the core, it was fused with the mysteries of dimensional world.
After the secret technique was used, a small dot would appear in the void, creating an independent space dimension to hide oneself within.
It was most certainly not life-saving as it claimed to be. As long as the opponent wasn't blind, they could definitely notice him.
It was just a basic secret technique, after all.
If he hid in a small space dimension when he couldn't defeat his opponent, he would be caught like a turtle in a jar unless he encountered an opponent with zero spatial attainments.
