Qin Fen returned to the hotel just after midnight. After showering, he sat down at his open computer, his fingers casually dancing across the keyboard, inputting a series of special characters into the notepad.

Even during the break, he couldn't entirely forget the mission. Although he didn't yet have the venue for the concert, he needed to start calculating the components that might be required for assembling the weapon.

After learning that the terrorist, Zajjad, possessed bio-beasts and could wield considerable strength, Qin Fen was forced to reconsider the necessary firepower. The speed and power exhibited by those creatures that day were still vividly imprinted in his mind.

To achieve a silent, untraceable shot that resulted in instant death, Qin Fen needed to meticulously calculate based on the experience gained from their previous encounter.

His ten fingers flew across the keyboard. Qin Fen chose the M82A1 heavy sniper rifle as the foundation for modification. This rifle, spanning 1,448 millimeters in total length, boasting a 12.7mm caliber, weighing 12.9 kilograms, and possessing an effective range of 1,830 meters—the former "King of Heavy Snipers"—had stepped down from its throne, but its formidable destructive power had not diminished in the slightest.

Qin Fen selected a few additional components, applying minor adjustments to the M82A1, significantly boosting its sustained fire capability. This meant that sacrificing a small degree of inherent rifle stopping power would have to be compensated for by the ammunition itself.

The M8 Depleted Uranium round. With a core made of a depleted uranium alloy, its density was 2.8 times that of steel. Forget a second-tier bio-beast fusion stage; even a target wearing light-duty jungle combat power armor at a distance of one kilometer could be completely penetrated with a single shot.

"I'll observe the site once I get there and see if any further adjustments are needed," Qin Fen decided, skipping the design of even a sidearm this time, resolving to take down Zajjad directly with the heavy sniper rifle.

Having made his preparations, Qin Fen showered and headed to bed. He had a few precious days off, and tomorrow he could finally meet up with some old friends for recreation.

"Kid, we meet again..."

The familiar voice—even in his dream, Qin Fen didn't need to open his eyes to know the owner belonged to the King of Perversion, Zeng Yicheng.

Before the man could finish speaking, Qin Fen subtly tensed his legs and shot his right foot out, initiating a sudden, throat-grabbing chokehold as a preemptive strike.

When facing the King of Perversion, relinquishing the initiative to him meant there would be no chance of turning the tide that entire night. Qin Fen understood this perfectly. Hearing the voice, he immediately chose the most devious counter-attack.

"A little interesting."

Zeng Yicheng's round, fat face broke into a smile of genuine appreciation. His already thick throat suddenly swelled, crisscrossed with bulging blue veins, instantly transforming to resemble the thigh of a bodybuilder, glistening with potent, fierce energy.

Qin Fen’s finger knuckles cracked audibly. With the Dragon-Elephant Prajna Art channeled, his middle and index fingers abruptly expanded beyond the thickness of his thumb, thrusting sharply toward his opponent's jaw—that notoriously difficult spot to strike.

Zeng Yicheng's smile remained unchanged, but he simply lowered his head and opened his mouth. Teeth that looked capable of crushing steel snapped towards Qin Fen's two fingers, as if preparing to devour a sausage.

A top-tier master resorting to biting? Could he possibly be any more perverse? Qin Fen retracted his fingers and turned them into a punch, generating a whipping gust of air as he drove it toward Zeng Yicheng's mouth.

Smash every tooth in your head! How will you bite then? A ruthless glint flashed in Qin Fen's eyes. Engaging the King of Perversion meant absolutely no room for courtesy; politeness toward him was cruelty toward oneself.

The King of Perversion’s neck twisted again. In that instant, his thick neck seemed utterly boneless, wrenching sideways to snap toward Qin Fen’s wrist.

Truly worthy of his title. Simply standing still, he could achieve such effects using only his mouth.

In the blink of an eye, the changes in their maneuvers accelerated. Qin Fen’s attacks alternated between brute force and insidious trickery, barely managing to hold an even match against Zeng Yicheng, who was employing Four-Star combat strength.

After fighting non-stop for two hours, Qin Fen’s stamina began to wane. Sparring with a master of this caliber demanded one hundred percent concentration and strength every single second. The expenditure was comparable to a real battlefield moment hanging between life and death.

Smack!

A foot slammed into Qin Fen’s face. The protective energy of the Dragon-Elephant Prajna Art instantly centralized on his face, forcing him back half a step, followed immediately by another kick striking the root of his ear—a spot notoriously difficult to defend.

Thump-thump-thump...

This time, Qin Fen staggered back four or five steps to the side, nearly collapsing onto the floor.

A flush crept up Qin Fen’s face. Normally, defending the ears was a priority during combat. Being struck there and consequently defeated was genuinely humiliating.

"Progress too slow, strength too weak," Zeng Yicheng commented dryly, his expression severe.

Slow progress? Weak strength? Qin Fen froze in disbelief. How could that be?

Among his peers, Qin Fen was confident his rate of strength growth ranked among the elite group. This wasn't arrogance; it was insight derived from his study of the Martial Way.

"Displeased?" Zeng Yicheng's smile hinted that he had anticipated this exact reaction. "Do you know how much force I was using against you during our fight just now?"

Qin Fen frowned, thinking deeply. In this specialized mental space, unless the opponent openly declared their star level, it was impossible to judge their true strength based on aura alone, as one could in the outside world.

"During the collisions, you were forced back by my pure strength, retreating only three steps. Calculating that, you should have been using power between Three-Star and Four-Star..."

Qin Fen made his judgment, startled to realize that the King of Perversion had suppressed his strength to a disadvantageous level yet still managed to fight evenly. This mirrored the way Qin Fen himself fought others outside.

"You are mistaken," the King of Perversion said, his usual perversion momentarily absent. He gently wiggled his slightly stubby, fat fingers. "I was using One-Star strength."

"What?"

Qin Fen began to question his own hearing. He was intimately familiar with the power levels of One-Star and Two-Star. Against his Four-Star Dragon-Elephant Prajna Art, he shouldn't have even been able to contend with a Three-Star master, let alone One or Two-Star.

"Why don't you believe me?" the King of Perversion asked mildly. "Recall carefully: how much slower was my speed during the fight compared to yours? Also, consider how you manage to fight Meteor-level masters outside using your Four-Star power."

Qin Fen was stunned. He had been too focused on winning during the fight. Stepping back now, he realized the opponent’s speed truly felt like only peak One-Star.

"Then, those three steps back..." Qin Fen started to speak, but his eyes suddenly lit up: "You used One-Star strength... for energy displacement?!"

Qin Fen answered his own question, his throat moving several times. He himself had performed energy displacement against Meteor-level experts using Four-Star power, but that required precise knowledge of his own strength and that of his opponent, combined with exacting control over his own output!

Even so, displacing the force of a Five-Tier Meteor expert while using Four-Star power had left Qin Fen strained.

Although he knew the King of Perversion was heralded as a super-master among masters, the feat of using One-Star power to counter Four-Star strength was utterly shocking.

Especially regarding the precision of strength control—after sparring with numerous experts, Qin Fen had slowly cultivated confidence, never believing anyone could surpass him in the exactness of force manipulation.

A difference of one star level demanded incredibly precise control over force. Achieving this when three star levels separated them, a situation that should have been utterly impossible to contest, was actually accomplished by the King of Perversion.

"You can't even defeat my One-Star strength, yet you believe you are progressing quickly?" The King of Perversion was more direct than the other mentors, delivering crushing words without a shred of mercy.

Qin Fen stood rooted to the spot. He had improved so much recently, leading him to believe his control over force was already exceptional among his peers. Now, it seemed his technique was utterly crude.

"Your foundation is indeed very solid," the King of Perversion conceded. "Even I, in my youth, might not have possessed a foundation as firm as yours. However, this is not enough; it is far from sufficient. Your control over your own strength, and your ability to counter your opponent's control, is very weak."

Qin Fen nodded slowly, realizing that with higher precision in force control, he could shatter the opponent’s precise displacement mechanics the moment they clashed, allowing superior force to win—no longer a problem.

Even against a newly ascended Meteor-level master, he could use the same technique to completely nullify their attack and achieve an over-level victory!

Control! Precise control! Qin Fen’s eyes shone brighter. He had been striving for an upward breakthrough these past few days, failing to see how many deficiencies he still possessed. His solid foundation wasn't quite as perfect as he imagined.

"But not bad," Zeng Yicheng's tone shifted. "You haven't completely followed my old path; you are trying to feel out one of your own. Although it is rough and needs significant polishing, starting to explore your own method at Four-Star strength places you in a very small minority."

This technique of administering a slap followed by a sweet date... Qin Fen managed a wry smile. Apparently, everyone used it.

Zeng Yicheng stretched his shoulders. "Kid, you have that powerful move, the Raging Torrent, and you even upgraded it based on your own insights. But don't you think you also need a truly perverse ultimate move?"

"I have been contemplating it," Qin Fen admitted. "Are you planning to teach me?"

"No, no, no..." Zeng Yicheng shook his wrist repeatedly. "My style is different from others. Perversity sometimes requires innate talent. Actually, your talent isn't bad; you just lacked a guide. A genuine perverse ultimate move isn't taught; it’s realized. So I can only give you the simplest direction: true perversion is something others can never anticipate. The moment you use it, they curse you for being shameless—that is true perversity."
