"Have you practiced this before?" Fang Songhe couldn’t help but ask.
Teaching videos of Spiral Force could be found online; some were genuine, and if one practiced according to them, they could master some basic techniques.
"No," Ji Xinghuo shook his head.
As he replied, he controlled his Star Power to strictly follow the pattern of Archimedes’ Spiral, without being distracted by speaking at all.
After observing for half a minute, Fang Songhe suddenly said, "Increase the speed, keep accelerating to your limit."
Ji Xinghuo immediately did so.
The Star Power curve within his arm sped up a bit right away.
The Archimedean spiral, also known as the uniform acceleration spiral, has a fixed angular velocity per unit time regardless of the speed.
Ji Xinghuo made the Star Power curve speed up with each rotation, accelerating with each loop he managed to reach his own limit very quickly, which was about fifteen times the initial speed. Any faster, and the Star Power curve would not maintain its cohesive form and collapse.
Fang Songhe’s face remained calm, but he was greatly shocked inside.
"Increase the Star Power curve."
"The number of curves should also reach your limit of cohesion," he continued.
Ji Xinghuo quietly did as told, his mind focused, gathering all his body’s Star Power into his arm. Every dozen seconds or so, another Star Power curve coalesced.
However, as the number of Star Power curves increased to five, the rotation speed inevitably slowed down.
He balanced the two, maintaining the rotation speed at a relatively fast level, cohesive without dispersion while slowing down the pace at which the Star Power curves were formed. With each additional curve, he spent one to two minutes adapting to the current state before condensing the next Star Power curve.
Nearly half an hour passed, and the total number of Star Power curves reached 29.
Over 70% of the Star Power inside his body was gathered in his arm; the transparent arm showed parallel curves spinning slowly around the central axis.
Each Star Power curve rotated at the same speed, perfectly matching the standards of Archimedes’ Spiral!
Yet, this was actually not the limit.
Although Ji Xinghuo appeared to be struggling, concentrating, with perspiration faintly visible on his forehead, this was just a facade for Fang Songhe to see.
He realized something during the practice.
If Spiral Force was as powerful and had infinite potential as Fang Songhe said, even surpassing Star Fall Ability, then it required faster neural responses and thinking speeds to perform a massive amount of calculations in battle to unleash the full power of Spiral Force.
This gave him another reason to integrate "High-frequency Thinking."
Ji Xinghuo quietly activated the Acceleration Ring for a few seconds, and indeed, the effect was evident, making it much easier to maintain the Star Power curves.
Seeing that he wasn’t increasing the number of Star Power curves, Fang Songhe nodded and then said, "Start running at your fastest speed."
Ji Xinghuo immediately started running around the Martial Arts Arena.
Movement can be distracting; at first, he didn’t dare to run too fast or swing his arms too widely. Once he gradually got used to the state, his running speed quickly increased, sprinting around the Martial Arts Arena, his arms flailing freely while the Star Power curves remained perfectly ordered.
Ji Xinghuo ran like a cheetah, freely and swiftly, yet stable.
"That’s enough," Fang Songhe called Ji Xinghuo to a stop. Seeing him return, not flushed or out of breath, with the Star Power curves within his transparent arm still maintaining at 29 and rotating at a uniform speed, he was utterly convinced.
Such frightening talent, Fang Songhe had never seen before.
Having joined the Extreme Martial Arts Academy a hundred years ago, apprenticed to Gun Saint Xing Lie, he had seen countless martial arts talents, but none had ever shocked him like Ji Xinghuo.
Even he himself, praised by his master back in the day as one of the world’s top martial arts talents, had undergone such tests when first learning Spiral Force; in terms of the number of Star Power curves, rotation speed, running, in every aspect, he was far less than one-tenth of Ji Xinghuo.
"A talent for the ages!"
"Perhaps even the master himself can’t compare to him..."
Fang Songhe’s heart churned like the overturning of rivers and seas, and for a long time, he couldn’t speak. At that moment, he had a strong desire to introduce Ji Xinghuo to his master!
However, considering that Ji Xinghuo was a Chi Xiao Knight and already famous, the Extreme Martial Arts Academy didn’t hold much attraction for him.
The Sword Bureau wouldn’t let him go easily either.
"I’ll find a way later," Fang Songhe thought to himself, "Such a peerless prodigy, even if he can’t be recruited into the Extreme Martial Arts Academy, should be befriended first."
He made his decision, yet his face remained composed.
"Archimedean spirals are the foundation of the foundations, your talent and performance far exceed my expectations, you will definitely master Spiral Force." Fang Songhe continued, "Now practice with a different part of your body."
He applied the potion to other parts of Ji Xinghuo’s body, introducing it as "Aether Star Display Potion," which made the body transparent, revealing the internal Star Power circulation and trajectory. It was a superb aid for practicing various Star Forces, achieving twice the result with half the effort.
Soon, Ji Xinghuo’s left arm, thigh, calf, abdomen, and back all became transparent, allowing a clear view of the inner Star Power status.
Under Fang Songhe’s guidance, he proceeded to control the Star Power’s rotation.
"You have completely mastered the Star Power curve of Archimedes’ spiral; now let’s move on to Fermat’s spiral," Fang Songhe said with a complex expression.
Back then, it took him a full three weeks to practice this far!
The big screen in the Martial Arts Arena switched to a new spiral line and the polar coordinate equation.
