This is an incredibly powerful technique that requires the selective manipulation of your chi. This technique follows the principles of the onion theorem, If you applied just the right sort of force to a physical object, you could project it into a sub-dimension, or sub-space as it was more frequently called. This was an environment that corresponded exactly with the normal universe, except that it was smaller. Submerge, travel a mile, and surface, and you would find that you had traveled a dozen miles. Complicated as that is, it is only the beginning. For there are levels within levels. You could push deeper, to realms that are even smaller, and where the travel differential is even greater. Theoretically, if you could dive deep enough, you could emerge anywhere in the universe at the same time as you left your previous location. By applying this principle with their chi user is able to greatly enhance their strength allowing them to easily make gigantic craters or kill opponents with single strikes. Their chi is able to pass through and damage almost any substance, literally tearing it apart by causing extensive internal and external damage. User’s chi also acts passively acting as a force field by creating a pocket of space just below the fabric of our reality protecting them from damage.
