This knee strike carried immense force, unyielding and powerful, crashing toward Uncle Chen's forehead with a dull thud, exuding an intense feeling of power!

To achieve the effect of a quick kill, Lu Yu didn't hold back at all with this knee strike, aiming directly for Uncle Chen's head, intending to kill him swiftly and then chase after Li Mufeng!

Li Mufeng had already driven away, and his speed was definitely not slow, so Lu Yu had to end this quickly. Otherwise, once the distance between them widened, it would be truly difficult to catch up!

For this reason, Lu Yu's attack was so ruthless!

This knee strike was tremendously powerful. Although it wasn't unleashed with full strength, it used eighty percent of True Power to ensure the battle would end quickly with a single deadly strike!

Seeing this knee strike blasting toward his face, Uncle Chen's expression changed dramatically, horrified.

After all, Uncle Chen was an expert himself, so he could entirely feel the terrifying force behind Lu Yu's knee strike just from the whistling wind!

If this knee strike landed, not to mention his head, even a block of granite would be shattered by it!

Thinking of this, he hurriedly crossed his arms in front of him, adopting a defensive posture to fend off Lu Yu's forceful knee strike!

But Uncle Chen underestimated the situation!

Until now, Uncle Chen was still judging Lu Yu's strength by normal standards, having no idea of the power contained in Lu Yu's knee strike!

He didn't understand at all that in Lu Yu's second stage, especially with his muscles fully engaged, Lu Yu's strength was overwhelmingly formidable!

"Defend?"

Seeing Uncle Chen's defensive stance, Lu Yu's lips curled upward as he coldly said, "Can you defend it?"

These words carried a hint of disdain in Lu Yu's voice!

Bam!

As soon as the words were spoken, with a muffled sound, Lu Yu's knee strike slammed directly into Uncle Chen's arms held in defense in front of him, and in an instant, an overwhelming force surged from Uncle Chen's arms!

This enormous power was so intense that Uncle Chen could not withstand it!

"How is this possible?!"

Feeling the surge of this overwhelming force in an instant, Uncle Chen couldn't help but exclaim.

Now he felt with his strength, he couldn't block Lu Yu's knee strike at all, and not only that, the bones in his defending arms were shattered by Lu Yu's formidable strength!

With his arm bones directly shattered, Uncle Chen's expression changed dramatically, but before he could react, the force of Lu Yu's knee strike didn't diminish, smashing directly onto Uncle Chen's face!

Bang!

In an instant, Uncle Chen felt as if his face was struck by a massive iron hammer, his mind went blank, and his consciousness quickly blurred!

The power of Lu Yu's knee strike was unparalleled, far beyond Uncle Chen's imagination.

If not for his strong arms partially absorbing Lu Yu's knee strike power, his head would have been directly shattered by it!

Yet, as Uncle Chen's consciousness rapidly blurred, Lu Yu's lips curled into a cruel smile as he slowly said, "Oh? You're not dead yet, your skills are indeed impressive!"

These words from Lu Yu were flat, without any emotion or intonation, like a machine, cold and unfeeling!

"Since one strike didn't kill you, let's add another!"

With a cold laugh, Lu Yu slightly moved and sent another knee strike directly towards Uncle Chen's head, his actions clean and quick, showing no mercy!

At this moment, Uncle Chen's consciousness was completely blurred, wholly unable to defend himself, like a slab of meat on a cutting board, left at Lu Yu's mercy!

"Die!"

With Lu Yu's low murmur, in an instant, this knee strike hit unwaveringly on Uncle Chen's forehead!

This time, there was no defense, no evasion; the knee strike was straightforward and perfectly accurate!

Bang!

With a muffled sound, Uncle Chen's skull shattered violently, his once dazed eyes filled with blood turning blood-red, his entire body collapsing to the ground like a puddle, silent and unmoving!

And from the start of the battle until now, only a little over forty seconds had passed!

At this moment, Uncle Chen, one of Li Mufeng's expert subordinates, was directly killed by Lu Yu in just over forty seconds, without any room for retaliation!

Glancing down at Uncle Chen's lifeless body, Lu Yu's eyes were filled with a cold light as he slowly turned, saying, "Next, it's time to chase Li Mufeng!"

With that, Lu Yu's entire body's muscles rippled, the muscles that were once bulging now returning to normal, but the muscles in his legs remained exceptionally developed!

In an instant, Lu Yu propelled himself onto the villa wall, raised his eyes, and looked ahead.

In the dark wilderness of the North Suburb of LA City, a car was speeding fast ahead, its bright headlights standing out in the darkness!

It was deep into the night, combined with the desolation of LA City's North Suburb, so that car could be none other than Li Mufeng's!

Since Lu Yu's rapid killing of Uncle Chen took only a little over forty seconds, Li Mufeng hadn't yet escaped too far, and Lu Yu could easily estimate that Li Mufeng was only about three kilometers away!

Three kilometers, at a normal running pace, would take about fifteen to twenty minutes, making it impossible to catch up to that car!

But for Lu Yu, this was hardly a challenge. In his condition with developed legs, he could fully sprint and cover the distance in a limited time, absolutely able to catch up with Li Mufeng!

Thinking of this, a sly grin spread across Lu Yu's face, and then he kicked off with his legs, shooting forward like an arrow, quickly closing the distance, his toes touching the ground for tens of meters at a time, filling anyone witnessing the scene with awe!

Sand! Sand! Sand!

At that moment, with the sound of footsteps, Lu Yu appeared to glide like the wind, moving through the night like a galloping leopard, raising gusts of wind behind him as he rapidly approached the speeding car!
