Wang Dong, I Request a Urine Test—Someone Used Technology

At her words, the students immediately picked up the pace, streaming out of the classroom and sprinting toward the field.

Lin You's expression remained unchanged, without the slightest hint of concern. Beside him, Xiao Xiao looked somewhat worried. After hesitating for a moment, she stayed behind as well and said softly, "I'll bolster your courage. Don't be afraid—you're not fighting alone."

"..."

Lin You could not help but laugh helplessly.

Zhou Yi looked calmly at Lin You, clearly curious. "Student, how did you avoid my pressure just now?"

Lin You had made no attempt to conceal his actions earlier. He had clearly used his Martial Soul, and even revealed his Soul Ring. There was only one Soul Ring, though, not enough to surprise her. In fact, at his age, having only one ring meant he lagged behind other talented students, who already had two or three. There was nothing worth noting about it.

Yet this student, who seemed so ordinary and unremarkable, had not shown the slightest fluctuation in his aura when facing the pressure of a Soul Emperor. Even when she deliberately intensified the pressure upon him, he had merely been forced to summon his Martial Soul and resist to some extent, while still having the spare attention to look at her.

She was curious, which was why she had deliberately kept Lin You behind. She wanted to see what was so unusual about him.

"It's nothing. Someone at home never bothers to rein in their pressure all day long. I'm just used to it."

Lin You's expression turned subtly strange. That little rascal Huo Yuhao was perfectly capable of restraining her mental pressure around Huo Yun'er, yet it somehow stopped working when it came to him. Sigh, how strange. It was truly baffling.

Zhou Yi's smile gradually stiffened, to the point that even her human-skin mask nearly failed to imitate it.

Used to it? Was that something a person could get used to?

Fine, fine. Burning newspapers at a graveyard—trying to fool ghosts, were they?

"Alright, alright. Hurry up and go."

Seeing that she would get no answer, Zhou Yi waved her hand, signaling for the two of them to go run their laps.

Lin You looked even more helpless. I told the truth, but you refuse to believe me. Long hair, short sight.

"Ah? Oh!"

Xiao Xiao hurriedly ran out after him, still completely confused.

What were they talking about? Why didn't I understand a single word?

Beyond the New Student Teaching Building lay Shrek Plaza.

The plaza was not particularly large, paved with broad slabs of Granite Marble. It was harder on the feet than the four-hundred-meter rubber track from Lin You's previous life, but Soul Masters had far stronger physiques than ordinary people. As long as they ran seriously, they could finish within one shichen.

Three hundred meters per lap; one hundred laps made thirty kilometers. One shichen meant two hours, so they had to run around fifteen kilometers per hour—about the cruising speed of a standard electric scooter.

After Lin You and Xiao Xiao joined the running formation one behind the other, quite a few people turned to look at them. Clearly, someone had been shocked by his bold move earlier.

Damn, this guy's got nerves of steel. None of us dared to poke the hornet's nest, but he actually said what everyone was thinking. He's a real boss.

As he ran, Lin You did not deactivate his Martial Soul. With a casual motion, he beckoned Xiao Xiao to follow behind him so he could break the wind for her, conserving her strength and endurance.

"Huh? Why isn't there any wind?"

Xiao Xiao stayed close behind Lin You, voicing her surprise.

"Uh, sorry. I almost forgot. Give me a moment—I'll set it up."

Lin You smiled awkwardly and focused his attention. He began guiding nearby Hydrogen Element and Oxygen Element to combine into Water Molecule, which slid slowly past both sides of Xiao Xiao at angles he had set, stirring up cool breezes carrying a moist freshness.

In an instant, Xiao Xiao's spirits lifted, and her whole body seemed invigorated.

In truth, Lin You had begun manipulating his Martial Soul the moment he started running.

Besides physical ability, running also meant dealing with Air resistance. The longer one ran, the more apparent that resistance became. That was why marathons often required pacers to break the wind and minimize the pressure of wind resistance.

Yet Air resistance was fundamentally tied closely to Particle Motion.

Air resistance was the force that hindered a moving object due to the elastic force exerted by the Air.

When Lin You ran through the Air, he interacted with it. These interactions included collisions and friction between airborne molecules and the surface of his skin, as well as changes to the Air's flow caused by his movement. Together, these effects produced the Air resistance that hindered his motion.

More specifically, when something moved through the Air, the molecules ahead of it were compressed, forming a high-pressure zone, while the Air behind it became sparse and formed a low-pressure zone. The pressure difference between front and back was part of Air resistance.

Therefore, when an aircraft approached the speed of sound, it encountered what was known as the sound barrier. At that point, the Air molecules ahead of it were heavily compressed, forming shockwaves and causing Air resistance to rise dramatically.

But once Lin You revealed his Martial Soul, all Air resistance vanished.

It was as though he had transformed into a Black Hole that devoured everything, greedily swallowing every type of element rushing toward him. Not only did his speed suffer no loss whatsoever, those elements even provided him with abundant kinetic energy.

Ignoring Air resistance sounded easy, but in reality, achieving such a feat was as difficult as ascending to the heavens for ordinary people.

Simply put, only a vacuum had no Air resistance.

Objects moving in a vacuum would drift endlessly into the distance, and Lin You was currently in just such a state. He practically seemed to be flying. If not for gravity holding him down, he would not even have been able to stop!

Even Xiao Xiao behind him found it much easier. Lin You had devoured all the resistance, while the flowing Air around her was filled with moist water vapor that replenished her body and eased her fatigue. Lap after lap, the other students gradually began gasping for breath, but her face remained rosy, her lips glistening with moisture, and her complexion full of vitality.

Time passed quickly. As the number of laps increased, the runners' breathing gradually grew heavier and their steps increasingly sluggish. Their pounding footfalls sounded like drumbeats. Only then did the gap in physical fitness and cultivation become fully apparent.

Even the pinkish-blue-haired boy who had been leading the pack was covered in sweat, but Lin You and Xiao Xiao were exceptions.

By now, those two had not even shed a single drop of sweat. They looked as relaxed as though they were taking a stroll.

Xiao Xiao, running behind him, looked even more at ease. After running all this way, she even felt that the longer she ran, the more comfortable her legs became. There was no soreness or weakness at all; the more she ran, the more energized she felt!

"This is so easy! The Oxygen Element is actually this amazing? You-ge is incredible!"

As she ran, Xiao Xiao still had plenty of energy to spare and chatted intermittently with Lin You ahead of her.

Lin You's Oxygen Element had long since been at work.

When the human body underwent intense exercise, an insufficient oxygen supply caused muscles to break down metabolically under anaerobic conditions, producing metabolic byproducts such as lactic acid.

When these byproducts accumulated in the muscles, they stimulated nerve endings and caused soreness, swelling, and weakness.

Increasing the body's oxygen supply could promote the breakdown and removal of lactic acid and other metabolic byproducts, thereby easing muscle soreness. This turned the exhausting, potentially body-damaging act of running into a lighter form of aerobic exercise.

"Huh?"

The pinkish-blue-haired boy running alongside the front turned in surprise to look at Lin You and Xiao Xiao, his eyes filled with shock.

Come on, we're all exhausted from running, and you two are treating this like a field trip?
