There is an immense chasm, a world of difference, between a Level 7 and a Level 8 Killing Technique.
Its hallmark is not just the need to simultaneously process nearly ten million increasingly complex Mental Power-Spiritual Energy aggregation modules per second. More importantly, it signifies a qualitative change in the intensity with which Mental Power can interfere with reality!
A Level 8 Killing Technique allows one to take the vast Mental Power already shaped into an Indestructible Projection and use it in an even more powerful way: to interfere with, and even distort, the real world!
This powerful interference is also known as—Intent!
Simply put, if a First-level Killing Technique was named the Ninefold Thunder Saber, the "Thunder Saber" in its name would be a mere metaphor, describing the saber's extreme speed and an offense as torrential as thunder.
But if a Level 8 Killing Technique shared the name Ninefold Thunder Saber, it would no longer be a metaphor!
