Exploring Immortality Cultivation-Chapter 326 - 80: First Level Sword, Harmony

"Why, why!" Wang Qi held his head, desperately pondering.

Why did my killing skill turn into Mosaic Slash?

This isn't scientific at all!

Bao Xiaoya leaned close to Wang Qi and asked, "Senior Brother, have you used this sword technique outside before? — You know, sometimes the moves you come up with on your own might have some issues that prevent them from working, and then here, the moves that don't work just show up as those disorderly, chaotic images."

"My move is supposed to 'work', how could it possibly not work?" Wang Qi said with a somber face, "And I clearly used it outside!"

Bao Xiaoya, with her index finger against her temple, speculated, "Could it be completely different from the existing spells of the Immortal Alliance, so the calculator couldn't deduce the effects? That shouldn't be the issue though. Unless it is one of the top Great Skills with a weight of ten, calculators can't parse it in a short time — and all the top Great Skills with a weight of ten are in the Spirit Rhinoceros Library, and they wouldn't need parsing... could it be... Senior Brother, is this possibly a new top Great Skill?"

Wang Qi shook his head, "That's impossible. I've seen the Great Skills with a weight of ten, the Life Flame of the demoness Ai Qinglan of Tianling Ridge... My swordsmanship consists only of 'a single strike', it can't possibly compare to something like the Life Flame."

"The effect of 'a single strike'?" Bao Xiaoya tilted her head looking at Wang Qi, "What do you mean by that?"

"My swordsmanship is based on the first-order logic of calculus... Do you understand predicate logic?" Since he had decided to collaborate with Bao Xiaoya on Probability Theory, Wang Qi treated her as one of his own, without hiding his own killing techniques, "My swordsmanship derives from predicate logic, and consists only of a single order, a single strike. But this one strike is absolutely valid, complete. However, because it is predicate logic, there can only be one strike."

In predicate logic, atomic propositions are broken down into individual terms and predicates. Individual terms are objects that can exist independently, and they can be either concrete objects or abstract concepts. Predicates are used to describe the properties of individual terms or the relationships between objects. Quantifiers, which are used in propositions to denote quantity, come in two forms: universal quantifiers (?), which mean "all" or "every", and existential quantifiers (?), which mean "there exists some" or "at least one". Predicate logic that contains only individual predicates and quantifiers is called first-order predicate logic, also known as narrow predicate logic.

First-order predicate logic is very primitive, so primitive that it can't even accurately describe a concept; "defining a natural number" is beyond the capacity of first-order predicate logic.

However, according to the Godel Completeness Theorem proven by Wang Qi, or what could be called the Wang Qi Completeness Theorem in Shenzhou, only first-order predicate logic is complete, and all valid propositions under first-order predicate calculus can be proven.

Therefore, if it is limited to a single strike, that absolutely valid single strike possesses unmatched power!

Wang Qi spoke earnestly, "You should remember, in this system, if you speak, you err, if you think, you mistake. The only things that can explain this principle are my paper and this 'single strike'."

This means, this single strike cannot be combined with any subtle sword techniques, cannot include any variations, it must simply be "one strike."

Bao Xiaoya nodded repeatedly, stunned. She asked, "Such a powerful single strike, Senior Brother, have you named it yet?"

"Just 'First-Order Sword'."

Bao Xiaoya looked flabbergasted and exclaimed, "How can such an amazing description have such a name?"

Wang Qi chuckled lightly, "You really are particularly stubborn about such trivial matters."

"Not at all," Bao Xiaoya blushed, a rare occurrence, "This is your first theorem, Senior Brother, and I personally think it's a remarkable theorem. Such an incredible theorem naturally leads to an incredible single strike, and this strike also deserves an incredible name..."

"Alright, let's think about what the cause might be." Wang Qi stood up, slashed twice more, still resulting in a large expanse of mosaic.

Damn it, Holy Light, mosaic, just need a Shadow to complete the Harmony Force, right? Or should it be called 'Harmony' in the Immortal Hero World?

Bao Xiaoya also thought hard, "The Illusion itself shouldn't have any problems... Senior Brother, your swordsmanship can be executed... Where exactly did the problem arise?"

Wang Qi swung his sword twice more and sighed, "Let me try a few more times..."

"You try a few more times, and you'll have to be ready to sell yourself to the Bo Family," suddenly, Feng Luoyi appeared in front of Wang Qi. He glanced at Bao Xiaoya, then said, "Or are you planning to marry into their family directly?"

Bao Xiaoya's face blushed, "Senior Feng, how can you make such a joke?"

"Teacher Feng," Wang Qi greeted, "What brings you here? Is it related to my swordsmanship? Do you know why this is happening?"

Feng Luoyi sat down and said, "Indeed, it is related. Do you know the principle of the calculator? You should understand this."

Wang Qi nodded, "At the most basic level, it's about the binary decision of existence and non-existence, yin and yang. Countless binary decisions accumulate to form a system..."

"A very perfect logic conceived by brother Turing, like a tower soaring into the clouds," said Feng Luoyi. "However, our mathematics is not yet complete. When building this system, no one can see whether its foundation is on solid rock or in a bottomless swamp."

This is another technological disparity caused by different physical laws in two worlds. The Cultivators have studied the soul for eighty thousand years. Although the Ancient Method has many misconceptions, much of the experience has been analyzed by the Modern Method. The understanding of the soul in Shenzhou far exceeds Earth's understanding of the brain.

Then, Elder Ji Turing drew on the human soul and used mathematics to analyze human thought, creating the first calculator, the Bronze Immortal.

This is actually a huge technology black box. Elder Ji himself is not fully aware of the principles of the calculator and the Ten Thousand Immortals Illusion Realm, but he still built it and learned to use it.

The Shenzhou Cultivators cast a tower from above the clouds; this tower reaches into the clouds, but those above the clouds could never see its foundation.

Then, Wang Qi's first-stage sword is a divine skill based on the block of mathematical logic, something outside of Elder Ji's theoretical realm. The Ten Thousand Immortals Illusion Realm could not reflect it.

Bao Xiaoya looked at Wang Qi, full of admiration, "To think... to think you went even further than Elder Ji!"

"If we're really talking about skill level, I still lack quite a bit compared to Elder Ji, it's just that I was very lucky this time," Wang Qi humbly admitted.

Feng Luoyi asked again, "Speaking of which, your first-stage sword is indeed a good move. I couldn't say before seeing it, but this should at least be a weighted-four swordsmanship, if you refine it further, you might achieve a weighted-six—this could even be recommended as a True Inheritor in the Five Great Sects."

Wang Qi said joyfully, "Actually, Junior has another gain."

Bao Xiaoya was shocked, "Senior Brother, you still had something up your sleeve? That's not very noble!"

After pondering for a moment, Feng Luoyi guessed, "Is it something like 'seeing through'?"

"Teacher Feng, you're incredible," Wang Qi expressed his admiration. "Only first-order logic is complete, and the more complex an opponent's swordsmanship, the larger the underlying logical system, and the more likely it to contain errors. I can spot the inconsistencies between an opponent's moves and break them. I've unofficially named it 'Striking the Discordant!'"

Wait, is this actually the Way of Harmony?
