Obviously, the density of stone is greater than that of water. If a stone is placed in water, it will immediately sink. But why does it skim across the water when skipping stones?

It’s speed! The speed carried by the stone allows a denser, heavier stone to skim across the water surface, and it’s only when the speed is exhausted that it finally sinks.
Austin’s eyes suddenly lit up with brilliance, and he had an epiphany.
"No, rather than speed, it’s about movement! The movement of the object changes everything!"
The stone’s movement allows it to defy convention by skimming across the water. If Fighting Qi could be moved in a way to sustain its high energy without dissipating, like the skipping stone on water, it could achieve powerful remote attacks!
Austin had no clear understanding of the essence of Fighting Qi. He only knew that it dissipates quickly after leaving the body. However, within and near the body’s surface, it’s unaffected. This phenomenon couldn’t be explained by mere diffusion from high to low concentration; there must be a more profound connection causing Fighting Qi to dissipate in the air.
But regardless of the relationship, movement can alter many physical properties. Austin’s analysis using the analogy of the stone skipping on water could be worthwhile.
"Movement can endow objects with different characteristics. The principle of Gale Foot is more about creating a vacuum wave with rapid foot strikes than just attacking an enemy. The vacuum wave allows the rapid movement of the air blade upon striking air, maintaining strong motion and retaining formidable slashing ability even after traveling long distances!"
From a realistic viewpoint, if a sudden vacuum appears in a localized space, the surrounding atmospheric pressure rushes into the vacuum area immediately, refilling it in an instant.
This characteristic is pretty similar to Fighting Qi, which also dissipates quickly in the air after leaving the body.
More importantly, aside from how Gale Foot’s vacuum slash wave allows for remote attacks, Austin couldn’t initially discern how the vacuum wave inflicted such severe damage.
But that fleeting inspiration enlightened Austin to a new world.
Perhaps the result is due to movement!
Not the vacuum wave’s movement, but the movement of airflow.
When water flows rapidly under high pressure, it can form a jet cutter that slices through metal and stone. Similarly, the movement of air can create astonishing effects.
In videos from his previous life, Austin once saw an experiment where airflow was accelerated to massive speeds using an air compressor, enough to sever a wooden log in seconds.
The principle behind Gale Foot might very well be the same!
Surpassing supersonic kick techniques cause extreme air compression upfront, forming a vacuum wave. Meanwhile, the airflow driven by the toe’s movement rapidly circulates along the vacuum blade’s surface at terrifying speeds surpassing the speed of sound.
During flight, the vacuum and airflow create a cycle and balance. The pressure difference between vacuum and atmospheric pressure maintains the rapid rotation of surface airflow. This causes the Gale Foot Slash Wave to advance swiftly while the small portion of airflow near the vacuum wave remains in high-speed motion until the vacuum wave is filled by air and dissipates, with the fast-spinning air blade losing momentum due to air resistance and fading away.
In Austin’s theoretical analysis, the Gale Foot Slash Wave consists of two critical components: the forming vacuum wave and the rapidly rotating air blade on its surface. Together, they form a perfect circular cycle, culminating in a remote attack technique like Gale Foot.
In this configuration, the rapidly rotating air blade is the main source of Gale Foot’s destructive power. It enables the vacuum wave to sustain itself briefly in the air and leverages the atmospheric pressure to convert its pressure differential into the air blade’s driving force.
"Gale Foot can utilize a collaborative cycle between vacuum wave and air blade to form a slash wave with powerful slashing ability. Can I create a magic-modified version, using detached Fighting Qi in combination with the air blade, to form a Gale Wave?"
Having clarified the cause and effect of Gale Foot, Austin’s eyes radiated with unprecedented brilliance.
"It’s certainly possible! Compared to vacuum, Fighting Qi as an energy can be controlled to move quickly, and combining the two to create a Gale Wave’s power will surely be stronger than the original Gale Foot!"
Understanding the principle opened everything up. The previously stalled Gale Foot Slash Wave experiment group moved to the next phase.
The first step in upcoming experiments is the Fighting Qi Sword, attaching Fighting Qi from the body to the sword blade.
Fighting Qi dissipates for unknown reasons after leaving the body. However, attaching it to one’s sword doesn’t cause this. In fact, within the realm of human warriors, many use techniques like Tornado Slash and Wind-breaking Slash, where Fighting Qi is attached to the sword blade to enhance its destructive power.
While attaching Fighting Qi to a weapon consumes it quickly, as long as the weapon is in hand, it won’t vanish like detached Fighting Qi that dissipates within tens of centimeters, increasing attack potency due to the weapon’s nature.
The first step of Fighting Qi Sword was mastered by all the test group’s beastmen within just a couple of days.
Previously, while the Gale Foot Slash Wave training group hit a bottleneck, the Extraordinary Beastmen in the test group hadn’t been idle. They practiced slashing thousands of times daily, trying to guide Fighting Qi onto the Bronze Greatsword and unleash it into a flying slash. Although with no results yet, each beastmen’s arm swelled from long hours of intense sword-swinging, laying a solid foundation for Fighting Qi Sword.
The second step involves rapidly driving and rotating the Fighting Qi attached to the sword.
This is no simple task, as Austin lacked a systematic training method for this. Even the combat techniques used by human mercenaries remained rudimentary, primarily focusing on Fighting Qi Sword as a basic means of applying Fighting Qi.
Without references, Austin had no choice but to let the beastman test group explore, exchanging insights daily to discover how to keep the Fighting Qi on the sword in motion.
