I fabricated myths to guide the revival of spiritual energy.

The wind was as sharp as a knife.

This is a wind gap between two main peaks, where gale-force winds of level ten or higher blow year-round. Gu Qing deliberately didn't use any formations to suppress the wind here; instead, he added a "Wind Gathering Formation," making the airflow even more violent and chaotic.

There is no podium, no blackboard, only countless flying swords swaying precariously in the wind, and a group of young people struggling against fate.

"No! My spiritual energy is about to run out again!"

A freshman from the sword cultivation department was pale and panting heavily. He had barely managed to hold out in the wind for less than a minute before the spiritual energy in his dantian was almost completely drained by the gale.

"Quickly sit down and meditate! Don't waste time!" someone beside me reminded me. "Use the sect's spiritual energy environment to recover!"

The reason these freshmen haven't collapsed from exhaustion is entirely due to the huge investment Gu Qing has made.

The concentration of spiritual energy here is far higher than outside, and the seemingly flowing and cumbersome "Taoist robes" they wear are actually engraved with miniature "spirit-gathering array patterns".

As long as they don't move around, the surrounding spiritual energy will slowly flow into their bodies.

Even so, this high-intensity competition still made them suffer greatly. Except for a very few exceptionally talented individuals, most of them had to come down and catch their breath for ten minutes after flying for just one minute.

The freshman who had been blown down by the wind rubbed his trembling thigh. "All our spiritual energy was used to fight the wind resistance. This is so inefficient! If we encounter enemies later, our mana bar will be empty before we even reach them. What's the point of fighting then?"

"Because you're stupid."

A clear, cold voice came from above.

Everyone looked up and saw a white shadow hovering in the very center of the wind gap—the place where the wind was strongest and the turbulence was most terrifying.

Chu Tian.

He is the undisputed number one genius of this year's sword cultivation department, and currently the only person who can remain calm for more than ten minutes in a strong wind.

At this moment, Chu Tian was still wearing that flowing, wide-sleeved Hanfu, his long hair dancing lightly in the wind. But unlike the others, he wasn't being blown about by the wind, and even the hem of his clothes didn't look disheveled as if it had been torn by the gale.

He was like a nail, firmly driven into the raging wind, and even... accelerating.

"Watch," Chu Tian said calmly to the students below, looking down at them.

Without further ado, he made his move.

Om-!

A very low, resonant sound came from the air.

Chu Tian did not lie down, maintaining his elegant posture with his hands behind his back. However, the air around him underwent a strange distortion.

If you had a God's-eye view, you could see it clearly:

Chu Tian did not use all of his spiritual power to push the sword, but instead used a large portion of it to create an invisible cone-shaped shield three feet in front of his body.

Spiritual power is omnipotent.

It can be a sturdy shield or a sharp spear.

At this moment, under Chu Tian's precise control, spiritual energy transformed into a perfect "aerodynamic rectifying cone." The violent airflow crashed into this invisible cone, was instantly and neatly cut apart, slid down the sleeve that should have been the "source of resistance," and then converged behind him.

"Spiritual energy is not just fuel."

Chu Tian's voice carried clearly through the air, "Spiritual energy is both fluid and solid. As long as you have a structure in your mind, it can take any shape."

call out--!

The next second, Chu Tian disappeared.

Although he was unable to break the sound barrier due to the limitations of his cultivation level, he still left a long white trail behind him—that was the turbulence generated by cutting through the air at high speed.

He was like a high-speed cruiser draped in a Taoist robe, instantly traversing the entire canyon.

The students below were all dumbfounded.

"Holy crap... is this what a top student is like?"

"He didn't fight the wind, he was... riding the wind?"

"He saved his spiritual energy from combating wind resistance and used it all for acceleration... No wonder he could fly for so long!"

"It's 'laminar flow control' from fluid mechanics!"

A bespectacled boy (a former physics Olympiad gold medalist) slapped his thigh, his eyes gleaming with fervor. "Before, we only knew how to use spiritual energy as a 'turtle shell' to withstand damage. But Senior Brother Chu Tian turned his spiritual energy shield into a 'fairing'! He eliminated most of the parasitic drag!"

……

Chu Tian did not merely demonstrate flight.

Sword cultivators are a profession of killing. Flying fast is not the goal; killing fast is.

He stared at a huge testing stone on the cliff in front of him.

That was specially made black basalt, incredibly hard; an ordinary Qi Refining stage disciple's flying sword could only leave a white mark when it struck it.

"Speed ​​is weight."

Chu Tian muttered to himself.

He extended two fingers and gently stroked the flying sword beneath his feet.

"Change."

The "spiritual light wings" that were originally deployed for flight stability instantly retracted.

All the spiritual energy no longer maintained lift, but was compressed into a single point at the tip of the sword, forming an extremely sharp "armor-piercing shock cone".

At this moment, the flying sword was no longer a weapon for slashing.

It turned into a high-speed kinetic energy armor-piercing projectile.

"go!"

Chu Tian flashed, becoming one with his sword.

With the terrifying speed accumulated previously, coupled with the instantaneous burst of spiritual power.

puff!

There was no earth-shattering explosion.

There was only a slight, muffled sound, like cutting into tofu.

The flying sword, carrying terrifying kinetic energy, instantly pierced through the three-meter-thick black basalt rock!

The flying sword emerged from the other end of the rock, its momentum undiminished, and embedded itself deeply into the mountain wall behind it, leaving only the hilt trembling wildly and emitting a buzzing sound.

The black basalt that was pierced left a smooth, mirror-like round hole that was transparent from front to back.

This is the high-temperature friction caused by extreme speed, which directly vaporizes the rock at the contact surface.

Chu Tian landed slowly and gently exhaled a breath of stale air.

His face was slightly pale, a sign of weakness after the sudden burst of spiritual power, but his eyes were frighteningly bright.

"I see……"

"In the past, we used swords, relying on the sharpness of spiritual energy to 'cut'."

"But by incorporating aerodynamic principles, we rely on speed to 'penetrate'."

"When the speed is fast enough, the air is no longer a resistance, but a track that locks the sword's edge. Any object in its path, if not hard enough, will be pierced instantly."

……

【Star-Picking Platform】

Gu Qing stood alone with his hands behind his back, on the edge of the Kunlun Mountains.

The biting wind made his robes flutter, but he remained motionless.

His gaze pierced through the clouds and landed on the black basalt rock that had been pierced.

The system panel appeared faintly before his eyes, and the data stream refreshed like a waterfall:

[Enlightenment Event Detected: The Kinetic Revolution of Sword Cultivators]

[Key Character: Chu Tian (Awakening Level: Extremely High)]

[Civilization Deduction:]

1. Your disciple realizes that the essence of sword cultivation is "ultimate offense".

2. The traditional techniques of "chopping, slashing, flicking, and stabbing" are redefined at this moment.

3. The sword technique, combined with aerodynamics, will evolve into "beyond visual range kinetic energy strike".

Gu Qing looked at the smooth, round hole, a satisfied smile curving his lips.

He had previously worried that these students might go astray, perhaps even carrying random bombs like fighter jets in pursuit of lethality.

That would be a inferior approach.

Sword cultivators are sword cultivators because they believe in "one sword can break all laws".

What does it mean to break through all laws with a single sword?

From a scientific perspective on cultivating immortality, this is:

When a flying sword has a sufficiently high cross-sectional density, a sufficiently high flight speed (approaching or exceeding the speed of sound), and a perfect aerodynamic shape, the kinetic energy it carries is enough to penetrate any defensive spell of the same level.

This is the "electromagnetic cannon" that belongs to cultivators.

"No need for unnecessary embellishments."

Gu Qing murmured to himself, his gaze deep.

"Chu Tian did a great job. He understood that the sword is not only a weapon, but also a vessel."

"As long as the aerodynamic design is solved, the flying sword can achieve a speed that ignores drag within the atmosphere."

"Then even a rusty iron bar becomes a powerful weapon at ten times the speed of sound."

Gu Qing turned around and looked at the still silent weapon-refining pavilion behind him.

Now that the sword cultivators' theories have been broken through, it's time to upgrade the hardware as well.

"Traditional flat blades, while advantageous for slashing, lack structural strength for high-speed thrusting and generate too much wind resistance."

"It seems that the next generation of the 'Kunlun-style flying sword' needs to be modified to a triangular armor-piercing structure that is more suitable for high-speed penetration."

The wind howled.

Below, Chu Tian was drawing his flying sword, surrounded by a group of freshmen whose eyes were gleaming with fanaticism.

Although this group of young sword cultivators is still very weak, they have to pant for a long time after flying for a while.

But they have found a completely new path to "extreme killing".
