Many Histories, The Time Has Come

Before making his move, Wang Qi had deliberately shouted "Uncertain Sword" for a reason.

The Uncertain Sword was not the Misty Unfixed Cloud Sword.

Most importantly, it lacked the process of turning into a probability cloud, of Sword Qi becoming clouds. Its core was not the observer-effect explanation, commonly known as the "Copenhagen interpretation."

This was a sword art he had perfected through reincarnation. Its core was DH—decoherent histories.

The states a system experienced within the same span of time were not unique.

The past was not unique, the future was not unique; only the "present" was unique—this was the explanation for wave function collapse! Because the "present" in which "observation" occurred was unique, it could only exist in one unique location, thereby forming definite microscopic particles!

And the Uncertain Sword was that very "present."

From infinite pasts, it cleaved out the single sword of the "present" from among infinite futures!

It was only that the mind-image spacetime of reincarnation had been simulated by Mi. Sword arts performed there might not necessarily be usable in the outside world.
