Chapter 198 Spiritual Vein Resonance, Difficult Fusion!
Inside the quiet room,

Lu Yu sat cross-legged, his eyes filled with extreme solemnity.

He took a deep breath and slowly adjusted his state. He had his own considerations regarding the removal of the spiritual veins from his body.

Although things are different now than in the simulation, where he has a Celestial Supreme Protector who can easily separate his spiritual veins, his situation is still special.

His spiritual veins were not innate, but were formed later by a strange fire. Strange fire is the most violent energy in the world, and spiritual veins formed with it are far less stable than naturally born spiritual veins.

If he had a congenital spiritual vein, there would probably be no way to remove it; but because it is a strange fire spiritual vein, it gives him a chance to separate it.

And the source of this opportunity, coincidentally, was the method given to him by the founder of this method, namely the Meridian Opening Method created by his younger brother Yan!

Yan Di originally created this method to test the stability of the strange fire spiritual vein, but he almost blew up the strange fire spiritual vein he had just created, and unintentionally created this meridian opening method.

Now that I want to strip away the spiritual vein, I need to use this vein-opening technique to break through the spiritual vein's limit and cause it to explode!

This decision was undeniably insane, but Lu Yu couldn't think of a better way to remove the spiritual veins from his body.

"To become strong, one must endure what ordinary people cannot..."

Lu Yu muttered to himself, a resolute look flashing in his eyes. Then he formed a hand seal, and countless golden light spots rose from the acupoints all over his body, like dazzling starlight.

In an instant, the surrounding天地能量 (heaven and earth energy) was frantically drawn in and converged.

Upon internal inspection, four particularly dazzling golden starlight rays emerged within his body, rapidly traversing his meridians like swimming dragons. As the Meridian Opening Technique continued to operate, the gathered energy became increasingly abundant, and Lu Yu's aura began to fluctuate violently, becoming extremely unstable.

After an unknown amount of time, when the four golden dragons within its body finally merged completely with the immense energy surging in from the outside, reaching a destructive critical point—

The aura emanating from Lu Yu's body had become extremely violent, sometimes rising violently like a volcanic eruption, and sometimes falling suddenly like a tide. A faint golden light shone through his skin, as if his whole body was about to burn up completely in the next instant!

Veins bulged on Lu Yu's forehead, and the cold sweat evaporated before it could even seep out due to the intense heat surrounding him. He clung to the last vestige of clarity, struggling to hold on, and gritted his teeth as he said:

"burst!"

Boom!

A deep, thunderous explosion suddenly erupted from his body! A searing pain instantly swept through his entire body!

The strange fire spiritual vein, meticulously crafted by the Floating Pagoda Fire, suddenly collapsed, and a terrifying energy shock erupted from within, instantly severely injuring him!
Blood gushed out, and even the bare white bones were exposed between the chest and abdomen!
The violent energy ripples relentlessly destroyed everything in their path. The defensive array of the quiet room broke down in response, the walls crumbled, and rubble flew everywhere!

Such a huge commotion immediately alerted the outside world. Little Fairy Doctor and Medusa arrived at the scene immediately, and what they saw was Lu Yu's miserable state of being covered in blood and barely breathing. The two of them turned pale instantly.

"Cough cough..."

Lu Yu coughed up several mouthfuls of blood, struggling to raise his hand to signal them not to come closer. He was covered in blood, with many deep wounds exposing bone, yet he still forced himself to speak, "It's alright... I'm fine..."

His voice was extremely hoarse and weak, each word sounding like it was uttered with all his might, clearly he was forcing himself to stay awake.

"How did it get like this..."

Little Fairy Doctor's eyes immediately reddened, and tears silently streamed down her face.

Lu Yu forced a smile, enduring the excruciating pain, and raised his hand to stop the two who were about to step forward. Without hesitation, he took out an eighth-grade, seven-colored Bone-Regenerating and Blood-Melting Pill and swallowed it.

Once the elixir entered the body, its immense medicinal power instantly dissolved, and its miraculous effects, known as "restoring flesh and bone and nurturing life," began to manifest.

The horrific wound on his chest healed rapidly at a speed visible to the naked eye, the new flesh tinged with a pale pink, and his breathing quickly became steady, as if he had been reborn.

Even so, Little Fairy Doctor was still worried and insisted on staying to take meticulous care of Lu Yu for several days until his injuries were completely stable. Only then, at his insistence, did she leave, turning back again and again. The quiet room returned to silence.

As Lu Yu sat alone, the harrowing scene of his self-destruction of a level-four ley line not long ago uncontrollably surfaced in his mind—the violent energy nearly tore his meridians apart inch by inch, his body on the verge of collapse, and the excruciating pain was still etched deep into his soul.

The fourth-level earth vein is already so terrifying. If this eighth-level divine vein were to explode out of control within his body... Lu Yu took a deep breath. The consequences would be unimaginable. He would probably be reduced to ashes in an instant.

A brief silence followed, the air thick with a suffocating heaviness.

However, after only a moment's hesitation, the last trace of doubt in his eyes receded like the tide, replaced by an unwavering determination.

The path to becoming a strong person is always against the will of heaven; how can one stop moving forward out of fear of potential dangers?
His eyes sharpened, and without the slightest hesitation, he swallowed another Grade 8 Seven-Colored Bone-Growing and Blood-Melting Pill that he had prepared beforehand.

The moment the pill dissolved, a powerful life force surged into his entire body.

"I choose three!"

As soon as he silently recited the mantra, Lu Yu felt a burst of light before his eyes. A ball of light, enveloped in a soft halo and seemingly containing eight divine rays flowing endlessly, slowly emerged.

That was the source of Qing Yanjing's Eight Divine Meridians. Even the slightest wisp of aura emanating from it caused the surrounding space to tremble slightly.

Before he could take a closer look, the dazzling purple light instantly entered his body.

The next moment, a strange energy radiating a noble purple light appeared around him. Upon introspection, eight brilliant purple moons appeared within his body, encircling him and radiating a vast and ancient power—this was Qing Yanjing's Eight Divine Meridians!
"hiss……"

The process of merging with the divine veins brought unimaginable pain. Lu Yu couldn't help but gasp, his brows furrowed, as if every inch of his meridians and every strand of his soul had been forcibly torn apart and then reshaped.

The power of the eight purple moons was so domineering that it almost burst his body!

Suddenly, countless fine cracks appeared on his body, like a piece of porcelain about to shatter. At the same time, the medicinal power of the Bone-Regenerating and Blood-Melting Pill rapidly unfolded, and a vast amount of life force surged out, painstakingly repairing these cracks.

His body cycled between shattering and rebuilding, just as Lu Yu's consciousness was about to be overwhelmed by the boundless pain—

The medicinal power of the Bone-Growing and Blood-Melting Pill has finally been exhausted.

At this moment, of the original eight purple moons within his body, five had already dissipated, but three still shone with intense purple light, like out-of-control ferocious beasts, frantically assaulting his body on the verge of collapse.

"Are you going to fail?"

Lu Yu's eyes darkened, and a strong sense of resentment welled up in his heart.

Just as he was about to fail, the black pagoda within his body suddenly trembled, its surface radiating a deep, eerie light! Countless ancient and mysterious runes emerged from the light, flowing endlessly around the pagoda, exuding an indescribable, vast aura!
The three raging purple moons seemed to be drawn by something, suddenly calming down. They no longer charged wildly, but instead emitted a gentle purple light, intertwining with each other to form a hazy glow that slowly enveloped the body on the verge of collapse.

Nourished by this gentle power, Lu Yu's body felt as if it were bathed in a spring breeze, and the excruciating pain he had experienced gradually subsided. His pale face gradually regained its color, becoming flushed with a faint rosy hue.

A warm current surged through my body, and every cell rejoiced, greedily absorbing this pure and gentle energy.

I do not know how long it has been,

Lu Yu slowly opened his eyes. Upon looking inward, he saw that although the Purple Moon was no longer visible, it had perfectly merged with his physical body, and there was no longer any distinction between them.

Before he could even feel the new power surging within him, an extreme exhaustion originating from the depths of his soul crashed over him like a tidal wave.

The thrilling fusion just now had completely exhausted his mind and physical strength. Now that the crisis had passed, his willpower, which he had been holding on to, suddenly relaxed. He felt a darkness before his eyes, as if all his strength had been drained away in an instant, and his body fell forward uncontrollably.

With a thud, he fell into a deep coma.
