Applied Immortality

Spiral, the oldest of the curves humanity had grasped, was something ancient Greece’s Archimedes fiddled with, even designing the first one that carried his name—Archimedes’ spiral.
“The spiral is… logarithmic!” Wang Qi was shocked as he watched.
Shifting on the outside but maintaining its core.
This spiral’s special property was that it remained logarithmic even after all the appropriate changes were made to it. Su Junyu’s punch left plenty of ingenious options for following through. However, Wang Qi could still calculate them all.
Wang Qi blocked again.
“Euler Heavenly Origin!” Su Junyu didn’t stop, turning his hand around and using the recoil to strike.
This time, the trajectory wasn’t as fancy, but Wang Qi’s hand felt numb on contact, almost unfeeling even. Su Junyu’s punches flowed like the ideal fluid with no drag as it struck his hand.
Euler equation—ideal fluid dynamics.
The difficulty spiked, but Wang Qi showed no fear, fighting back each time.
Wang Qi’s eyes shone as he applied more force upon contact with Su Junyu’s fist. The two punches crossed, and the air shimmered around them!
The surging force unleashed by the Euler equations came fast and fierce. Wang Qi staggered two steps. As he raised his leg, Su Junyu pressed forward and kept their distance fixed.
“Cycloid!”
Su Junyu waited for him to recover before punching again.
Cycloid, or curve of fast descent, described an object’s changes under the influence of gravity. Born from the motion of a circle, this curve—called a roulette or, more precisely, a cycloidal curve—originated from the circumference, yet its arc length maintains a rational ratio to the circle’s radius. Truly, a marvel of mathematics!
Su Junyu’s fist contained endless variations as it struck, leveraging Divine Province’s gravity, using no spiritual power, just martial skill, and spinning in the air like a hurled axe for Wang Qi’s head.
“Ha!” Wang Qi shouted, using his left to intercept, still tangent to Su Junyu as always. The two fists crossed, and the air cracked.
“Formless!”
Su Junyu used the Myriad Arts Sect’s famous Formless Hand. The Weierstrass function was endless, making direct observation impossible in determining Su Junyu’s fist’s trajectory.
However, having grasped Shifting Step, Wang Qi could do it.
“Ya!” Wang Qi blurted, his fist exploding as it met with Su Junyu’s, but unlike the previous strikes, this one had to contain a bit more oomph.
“The Bernoulli family’s Heavenly Origins!” “Point group!” “Complex variation!” “Gao distribution!”
Su Junyu’s every strike would come after he shouted the theory behind it, using the fist as the blackboard in explaining their use with smooth motions. Wang Qi used his Divine Hexagram Computation and Book of Geometry to the max, running numbers like no tomorrow just to predict and block the blows.
The process had Wang Qi’s Myriad Arts Sect’s mental arts stirred. As math was run longer, Wang Qi’s yin-yang diagrams in his acupoints grew more pronounced, and the Heavenly Position axis was strengthened. At the same time, the many issues he couldn’t grasp regarding math and martial arts, and martial arts and math, all became clear with every punch.
This was the miracle of calculation!
This was the beauty of math!
Pushed around every time, Wang Qi found the exchange exhilarating.
“Awesome! This is how you grasp the mysticism of calculations.”
Like an addict, Wang Qi groaned as he got his fix, lunging with clasped hands. Su Junyu frowned, pushing a single palm ahead. Wang Qi winced, finding the palm far more complex than just coming at him in a straight line. He couldn’t see through it!
All the marvel of the antelope hanging its horn, all the profundity of the white rhino crossing water couldn’t begin to describe the intricacies of this palm. (Tamon: from a Song Dynasty poem.)
Su Junyu’s palm came for Wang Qi, pushing a soft force into his body and blocking Wang Qi’s spiritual power. Wang Qi was pushed back three steps, almost sticking to the wall.
“How was it?” Su Junyu said, “This is the true comprehension of the Myriad Arts Sect’s mental arts. Splitting your focus on understanding math and mental arts would never intersect them. This fight showed the use of numbers in moving spiritual power, combining both aspects and showing you the solution.”
Xiang Qi interjected. “Hey, moneybags, how’s the brat’s quality?”
Su Junyu entered deep thought, taking out “Brief Explanation of Nonlinear Celestial Changes Series and Its Characteristics,” saying, “You’ve been using this one, right?”
Wang Qi had to give Su Junyu credit for all his knowledge. “Yes.”
Su Junyu did something that left everyone gawking—he ripped the paper apart. “Stop it.”
“But…”
“No buts.” Su Junyu was firm. “Modern cultivation’s Secular Stage’s greatest issue is going too fast. The Nonlinear Celestial Changes Series can help you speed up your spiritual power improvements with Heavenly Origins, but few train it. Why?
“Because modern cultivation’s research into the human body has gone beyond what is needed to cultivate, making Golden Core Realm a guarantee. Geniuses have tons of time!
“It is all to purify your spiritual power, shape your foundation, and polish your Golden Core. The process needs stability and time for a truly strong foundation!
“Normal cultivation is fast enough as it is and doesn’t need any extra boost!”
Wang Qi wanted to retort. “That’s not what I meant…”
Xiang Qi changed the subject. “Junior Brother, you’re talking about how Supreme Lord, Daoist Proscribe, and all in that generation reached Primordial Spirit in years and Unfettered in a hundred? Yes, with their limited knowledge they didn’t think of taking more time to polish themselves, but do you know of the price they paid?
“To complement his foundation, after becoming an Eminence, Supreme Lord went to Myriad Arts Sect for advice from Arbiter of Arithmetic about bitter seclusion. Daoist Proscribe had it worse; he almost lost his life in his attempt to become Unfettered.”
“That’s not it.” Wang Qi cut them off. “Even if it’s just reference material, it’s still a good source of merits!”
