Solving the case: Combining the police dog's olfactory genes at the beginning

His right arm was thicker than an average person's thigh, and his elbow bulged out like an iron ball encased in flesh. The muscles on his forearm were clearly defined, and blue veins bulged under his skin.

He held his right arm across his head, the bones of his arm forming a natural barrier under the wrapping of muscles.

Luo Fei's foot came crashing down.

The right foot slammed into the center of Tenyu Kamikura's forearm, hitting the ulna and radius bones side by side, the strongest part of the forearm.

The sound of the impact was different from the previous two—the previous sounds were low and muffled, while this sound was sharper, like a hammer hitting a chopping board.

The stone slab beneath Tianyu Shencang's feet shattered simultaneously under the force of the kick, fragments flying out and hitting his calves before bouncing away. Luo Fei's kick sent him staggering back several steps, each step leaving a cracked footprint on the stone slab.

The skin on his arm where he was kicked turned white from the impact, then quickly turned red—bruising caused by ruptured capillaries.

His arm was both painful and numb, the numbness extending from his wrist to his shoulder. His entire right arm trembled uncontrollably after blocking the kick, the trembling visible to the naked eye.

Luo Fei landed on the ground, his knees bending to cushion the impact. Then, without pausing, his right leg, using the momentum of the landing, swept half a circle from the outside, aiming at Tianyu Shencang's neck.

This was a high roundhouse kick, the arc of the leg from bottom to top was fast and fierce, the instep was stretched straight, and the veins on the instep bulged under the skin.

The wind generated by his leg as it swept through the air brushed against Tenyu Kamikura's neck, blowing all the hairs on his neck down.

Tenyu Kamikura raised his right arm again to block.

Luo Fei's instep swept across the outside of his forearm. This time, the force was slightly less than the kick that came down from the sky, but it was still terrifying enough.

A dull thud echoed as the instep and forearm made contact. The muscle in Tenyu Kamikura's forearm caved in towards the bone before bouncing back. The force traveled through his arm and slammed into Tenyu Kamikura's neck.

As he blocked with his right arm, he turned his neck slightly to the left, so the instep of the foot did not directly hit his neck, but the force was transmitted through his arm and still knocked his head to the left.

His head was tilted at least ten centimeters to the side, and the tendons in his neck were stretched to their limit under his skin.

Luo Fei pulled his foot back, his toes barely touching the stone slab, the momentum still lingering. Using the momentum from pulling his foot back, he threw a right punch from his side, the fist arcing upwards, aimed at Tianyu Shencang's chin.

This punch was an uppercut, and the point of force was not the shoulder, but the rotation of the entire body—his waist rotated half a circle as he threw the punch, and his spine was like a spring that had been tightened and then suddenly released, transferring all the power of his body to his fist.

Just how fast was Tenyu Kamikura's reaction? Even with his head tilted to the side, his left hand still managed to reach out and grab Luo Fei's punch.

His palm was more than twice the size of Luo Fei's fist, and his five fingers, spread out like five steel claws, gripped Luo Fei's fist.

His fingertips collided with Luo Fei's knuckles, producing a short, sharp sound. His fingers tightened sharply the instant they gripped, the force of his knuckles pressing down on Luo Fei's fist through his skin.

But Luo Fei had already thrown out his other fist.

His left fist struck from the right side of Tenyu Kamikura, a slight creaking sound coming from his shoulder joint as his arm swung. It was a hook punch, sweeping horizontally from the outside in, the back of his fist aimed at Tenyu Kamikura's abdomen.

Tenyu Kamakura's right hand was still numb, and the speed at which he raised it was a fraction of a second slower. It was this fraction of a second delay that created a gap in his defense.

Luo Fei's left fist slammed into Tianyu Shencang's abdomen. The fist struck a spot two or three centimeters above the navel, precisely where the rectus abdominis muscle is weakest.

Although Tenyu Kamikura's abdominal muscles were bulging as hard as rocks, Luo Fei's punch caused them to cave inwards. The force of the punch passed through the rectus abdominis muscles, through the internal organs in his abdominal cavity, and even shook his stomach.

A look of pain crossed Tianyu Shencang's face. His lips were clenched, his teeth were clenched, and his eyes were narrowed to slits. The pain in his abdomen made him involuntarily bend over, and his left hand, which was gripping Luo Fei's fist, loosened its grip.

It felt like a fire was burning inside his stomach, and his stomach was spasming violently, as if someone inside him was twisting his stomach with their hands. He grimaced in pain, revealing his two rows of clenched teeth.

But his counterattack arrived at the same time.

He lifted his right foot off the ground and kicked out at Luo Fei's chest. This kick was more powerful than any of Dark Moon Asura's previous kicks, and the muscles in his leg made a muffled thud as his foot pushed off.

His foot landed on Luo Fei's crossed arms in front of his chest—Luo Fei had already pulled his arms back to protect his chest at the same time he punched Tian Yu Shen Cang in the abdomen with his left fist, so the kick landed right on the spot where Luo Fei's forearms were crossed.

Luo Fei was kicked and slid backward, taking four or five steps back on the stone slab before regaining his footing. His shoes scraped against the stone, and a dull pain came from the spot where he had been kicked in the arms, but it was much less painful than when he had been knocked away by the Iron Mountain Lean.

He shook his arms, and the muscles in his arms relaxed again as he did so.

After he regained his footing, he raised his head and looked at Tenyu Kamakura, who was still slightly bent over due to abdominal pain. He opened his mouth and let out a loud roar from his throat.

"Again!"

The sound seemed to explode from the depths of his chest, causing the surrounding air to tremble. Then, he pushed off with his feet, sending the shattered stone slabs flying beneath him, and his body hurtled towards Tianyu Shencang like a cannonball.

Luo Fei's body collided with Tianyu Shencang's body in the center of the square, and their fists slammed into each other at the same time.

Luo Fei's right fist struck Tianyu Shencang's left shoulder, while Tianyu Shencang's left fist slammed into Luo Fei's right chest. Both of them took a step back at the same time, and then immediately pounced on each other again.

The stone slabs kept breaking under their feet, and the powder from the broken stones mixed with volcanic ash, rising up like a layer of gray mist that enveloped the square.

Their punches and kicks were incredibly fast—Luo Fei threw seven punches in a single second, with the trajectories of his fists simultaneously attacking Tianyu Shencang's head and torso from three directions: front, side, and top.

Tianyu Shencang's arms formed a wall in front of him, his forearms and fists constantly colliding with Luo Fei's fists, each collision producing a dull thud.

At the same time, his legs were also moving, his knees and feet constantly attacking Luo Fei's abdomen and legs from below, forcing Luo Fei to divert some of his attention to defend his lower body.

After exchanging more than a dozen blows, Luo Fei's left fist passed between Tianyu Shencang's arms and slammed into his chin. Tianyu Shencang's head snapped back, but at the same time, his right foot kicked Luo Fei in the abdomen.

Luo Fei's body was kicked and slid back two meters, his shoes leaving two white marks on the stone slab. As soon as he regained his footing, Tianyu Shencang rushed up, his right fist slamming down from above, the shadow of the fist rapidly magnifying in Luo Fei's pupils.

Luo Fei dodged to the side, and Tianyu Shencang's fist slammed into the spot where he had just been standing. The fist struck the stone slab, shattering it into pieces, with fragments flying outwards from the point of impact. As Luo Fei moved to the side, his right elbow struck Tianyu Shencang's ribs, the tip of his elbow hitting his ribs. Tianyu Shencang groaned and his body swayed to the left.

But at the same time, his left fist swept in from the side and hit Luo Fei's shoulder, causing Luo Fei to stagger two steps to the right.

The two men steadied themselves simultaneously, turned around at the same time, and threw punches simultaneously. Their fists collided in mid-air, knuckles against knuckles, bone against bone, the sound of the impact echoing across the square.

The scabs that had already congealed on Luo Fei's fingers shattered under the force of this punch, and blood splattered from his knuckles onto Tianyu Shencang's fist.

Tenyu Kamakura also had a wound on his fist. Although his skin didn't have a tear as big as Luo Fei's, the skin on his knuckles was also broken, and blood was seeping out from between his fingers.

Neither of them backed down.

Luo Fei's eyes were fixed on Tianyu Shencang, and Tianyu Shencang's eyes were also fixed on Luo Fei. Their pupils reflected each other's faces; Luo Fei's face was smeared with volcanic ash and his own blood, while Tianyu Shencang's face was covered in sweat and dust.

Their breathing was heavy, their chests heaving, but the fighting spirit in their eyes did not diminish in the slightest.

They've already exchanged forty or fifty blows.

When Tenyu Kamikura threw his fifty-second punch, he suddenly sensed something was wrong.

His punch didn't slow down, its power didn't diminish, and its trajectory remained precise. But when he pulled his fist back, he felt it—his muscles reacted about a fraction of a second slower than before.

The difference is extremely small, and ordinary people cannot perceive it at all. However, for a powerhouse like Tianyu Shencang, no slight change in his body can escape his perception.

His brow furrowed slightly. The wrinkles on his forehead deepened, and two vertical lines creased the skin between his brows. He continued to punch, block, and dodge, but part of his attention shifted to his physical condition.

He could feel his heart beating faster than before, pounding more frequently in his chest than he had expected. His breathing was also shallower, with less air being taken into his lungs and shorter intervals between breaths.

He glanced at Luo Fei.

Luo Fei's punching speed and power remained unchanged. His punch came at the same speed, with the same ferocity, and with the same precision as the first punch.

His breathing rhythm was exactly the same as when they first started fighting—deep and steady, with each inhale reaching the bottom of his lungs and each exhale clean and crisp.

There was no sign of fatigue on his face, no sweat on his forehead, no unfocused gaze, and no slowing of his movements.

Tenyu Kamikura's heart sank.

Weighing 300 pounds, this massive body, while granting him overwhelming power, also brought an unavoidable problem—energy depletion.

Every punch, every movement, every block he made consumed far more energy than Luo Fei's. It's like a truck and a car traveling at the same speed; the truck will definitely burn more fuel than the car.

He and Luo Fei exchanged more than fifty blows, each one a full-force attack, and his physical exertion had exceeded the limits his body could withstand.

His pace began to slow.

It wasn't that he wanted to slow down, but rather that his leg muscles were starting to fatigue after continuous high-intensity exertion. Muscle fibers accumulated a large amount of lactic acid after repeated contractions and expansions, and this lactic acid buildup slowed down the muscles' reaction speed.

When he stomped his feet on the stone slabs, he didn't exert as much force as before, and the distance he covered was shorter as a result. The sound of each step he made on the stone slabs was also softer than before.

Luo Fei noticed this change.

His eyes caught the change in Tianyu Shencang's footsteps as he moved. When Tianyu Shencang moved earlier, each step he took could shatter the stone slab, but now, as he stepped on the stone slab, only a few cracks appeared, instead of the entire slab breaking apart.

Luo Fei narrowed his eyes slightly, realizing that Tian Yu Shen Cang's physical strength was declining.

He decided to continue with the strategy of attrition warfare.

He pushed off with his foot, lunging forward, his right fist aimed straight for Tianyu Shencang's face. Tianyu Shencang raised his left arm to block, but Luo Fei's fist struck his forearm, the force of which made Tianyu Shencang's arm go numb.

While parrying, Tenyu Shencang's right fist struck Luo Fei's abdomen. Luo Fei dodged to the side, and then raised his left knee to strike Tenyu Shencang's side.

Tenyu Kamakura slapped his knee away with his palm, but Luo Fei's right fist swept in from the side and hit his shoulder.

The force of this punch was just as great as before, and Tenyu Kamikura's body swayed to the left. He took a step to the left with his right foot to regain his balance, and his foot made a heavy thud as it hit the stone slab.

His breathing became more rapid, his chest heaving more dramatically than before, and each exhale was accompanied by a hot breath.

On the live stream screen, the camera clearly captured the changes in Tenyu Kamikura's breathing. His chest heaved faster and faster, the fabric of his kimono rising and falling incessantly at his chest.

Sweat began to bead on his forehead, trickling down his hairline, down his temples, and onto his cheeks, where it condensed into beads and dripped down his chin.

The flush on his face began to fade, replaced by a lighter skin tone than usual, and the color of his lips also became lighter.

The live chat exploded immediately.

"He's tired!!! Tenyu Kamikura is tired!!!"

"See? He's not sweating at all! He wasn't sweating at all just now!!"

"Your breathing has become much faster; this is clearly a sign of exhaustion."

"It's no wonder someone weighing 300 pounds gets tired after playing at such high intensity for so long." (End of Chapter)
