"Alas, incompetent doctors cause harm!"

Seeing that Liu Yu was stubbornly set in his ways, Yun Xiao could only sigh in exasperation. Even though he knew the method that guy was using was wrong, there was no way to intervene now—doing so would be nothing short of creating chaos.

However, noticing that Lu Liancheng and the others showed no signs of concern at all, Yun Xiao relaxed. The truth was that even he had the means to cure the man after Liu Yu's inevitable failure. Since the guy was hell-bent on heading down the wrong path, there was nothing more to be said.

Yun Xiao's sigh was not concealed, and nearby Meridian Refining Masters heard it clearly. Instantly, their gaze towards him became even more disdainful.

Compared to an old fool so advanced in age still participating in the Refining Cloud Mountain disciple selection, everyone naturally preferred to believe in Liu Yu, whom they were somewhat familiar with.

After all, Liu Yu's reputation preceded him, and as a genuine Spiritual Rank Advanced Meridian Refining Genius, this lethal Gu worm poison should pose no problem to him.

Thud, thud, thud, thud...

One must admit, Liu Yu's Meridian Refining technique was indeed impressive. As he unleashed the vast Power of Soul of a Spiritual Rank Advanced level, his right hand swiftly rose to tap the man's chest and abdomen over a dozen times in a fluid and graceful motion.

Boom!

As Liu Yu tapped on the points in the man's chest and abdomen, a strong aura suddenly erupted from the once feeble man. It was unclear whether this belonged to the man himself or to Liu Yu.

This potent aura seemed to possess a certain spirituality, roaming around the man's body before finally concentrating on his liver and gallbladder, as if something was being forced out.

"Come out!"

At a certain moment, Liu Yu shouted loudly, his right hand forming a claw above the man's chest and abdomen, as if it was grasping something invisible.

"Hmm?"

However, just when everyone believed the so-called Gu worm would be caught by Liu Yu, they waited a moment and saw nothing. Liu Yu's right hand remained empty.

"Come out!"

Apparently sensing the strange looks from the crowd around him, Liu Yu felt his face grow hot. He roared once again, the aura in his hand growing more than twice as strong, indicating he was using all his strength.

Unfortunately, Liu Yu's initial judgment was mistaken; he used methods to coax out a common Gu worm, which had minimal effect here. Pitifully unaware, this led to the current embarrassing situation.

Despite his loud shouts, nothing appeared. Liu Yu felt as if his face was being torn off and thrown to the ground to be trampled upon. In that instant, he failed to realize his judgment was wrong.

"I still won't believe it!"

Feeling his dignity damaged, Liu Yu clearly refused to accept defeat. His entire body's Meridian Qi surged, and his Power of Soul was recklessly unleashed, showing his resolve to take a gamble.

"Hey, if you keep watching, that person will lose their life!"

Just then, a somewhat familiar voice rang out, unmistakably Yun Xing. When everyone turned to look, they saw him addressing Lu Liancheng and the others seated in the chairs.

"Enough!"

This time, after Yun Xiao spoke, the sub-chairman Lu Liancheng lightly sighed. Then, an overwhelming force suddenly erupted from beneath Liu Yu, directly pushing him back three or four steps before he could regain his footing.

"Earth Element!"

Even though most people present were only at the early to middle stages of the Qi Seeking Realm and had a Spiritual Rank Three Realms cultivation at best, they were familiar with the method Lu Liancheng used. It was clearly a step above the Earth Power typically wielded by a Qi Seeking cultivator.

Under the onslaught of the Earth Element, even though Lu Liancheng held back, it wasn't something Liu Yu, an early-stage Qi Seeking Realm cultivator, could withstand. Standing steady, his face had already turned extremely pale.

Truthfully, Liu Yu wasn't injured. His pallor was due to realizing certain things from Lu Liancheng's actions. It seemed he had indeed misjudged the situation earlier.

In fact, after employing his ineffective techniques, Liu Yu had already sensed that the problem within the man's body wasn't what he thought it was—a Gu worm. Unwilling to admit defeat, he decided to stake everything on one last attempt.

Such methods might have allowed Liu Yu to succeed, but the greater likelihood was that the violent impact would first kill the man, who was already on his last legs.

Familiar with the inside story, Lu Liancheng and others initially could remain indifferent when Liu Yu took action, but when real harm to life was possible, they couldn't refrain from intervening.

Watching this scene, many people were contemplative, looking at Yun Xing with a peculiar gaze, thinking to themselves that this old fellow, who joined the Refining Cloud Mountain disciple selection at the age of forty or fifty, seemed to have some skills after all.

The gaze from Lu Liancheng and others was not on the pale-faced Liu Yu, but rather focused with interest on the person who spoke earlier, as if contemplating some words.

"Since this gentleman can see the hidden intrigue, he must have exceptional skills. Would you care to show us a demonstration?"

Lu Liancheng stared at Yun Xiao for a while, his words echoing the thoughts of everyone, as Yun Xing appeared knowledgeable, though it was uncertain if he indeed had extraordinary skills.

"Then, I'd be honored to oblige!"

Yun Xiao naturally wouldn't refuse such a request, especially since he originally came for the selection slot. Since Liu Yu was outmatched, it was time for someone capable to step up.

Under the peculiar gazes of the crowd and Liu Yu's gloomy expression, Yun Xiao leisurely walked forward and, just like Liu Yu earlier, extended the five fingers of his right hand, placing them on the person's abdomen.

"Come out for me!"

Just when everyone expected Yun Xiao to unleash his Power of Soul, showcasing his skill level, he instead shouted these somewhat familiar words.

"Is this guy doing it on purpose?"

Observing Yun Xiao's actions and hearing words identical to Liu Yu's earlier, everyone had a peculiar look on their faces, as aside from not unleashing any Power of Soul, his actions were exactly the same as Liu Yu's.

"Damn old guy, just you wait!"

Especially Liu Yu, not far away, was nearly exploding with anger, as he clearly noticed that person cast him a discreet glance after shouting, the meaning of which was self-evident.

However, Yun Xiao's identical actions and words with Liu Yu ended there, for after his shout, he slightly lifted his right hand's five fingers, and a flash of yellow light passed through. In his palm was a struggling, chirping insect.

"Is that... a Yellow Gall Insect?"

Some knowledgeable Meridian Refining Masters, observing the yellow insect struggling in Yun Xiao's hand, were contemplative, while many turned their gazes to Liu Yu, the princely heir of the Liu Family, eyes filled with doubt.

After all, Liu Yu's initial judgment was that the person was poisoned by a Yellow Gall Insect, but he failed to extract it, leading to failure.

"This isn't an ordinary Yellow Gall Insect!"

Amidst the crowd's doubts, Yun Xiao was already holding the continuously struggling yellow insect, turned around leisurely, and said, "Accurately speaking, it should be a mutated Yellow Gall Insect!"

"Mutated Yellow Gall Insect?"

Yun Xiao's words led everyone into deep thought, while the eyes of Lu Liancheng and other strong members of the guild brightened due to Yun Xing's surprising performance.

"A mutated Yellow Gall Insect can't even be considered a true Yellow Gall Insect, as they not only cause the inner gallbladder to become poisonous, but also affect the heart, liver, spleen, and lungs without exception!"

With a slight exertion of Yun Xiao's hand, the mutated Yellow Gall Insect squealed angrily, but was unable to escape.

Strictly speaking, this mutated Yellow Gall Insect doesn't even qualify as a Vein Demon. It's a foreign insect relying on the gallbladder fluids inside the human body, akin to a parasite but containing lethal poison, which would eventually cause the poisoned person to die.

However, such grade of Yellow Gall Insect poses little challenge to the Earth-rank Pulse Refining Masters of the Meridian Refining Master Guild, who likely discovered the mutation long ago.

But Liu Yu, a Spiritual Rank Advanced Meridian Refining Master, was still far from competent in both Meridian Refining experience and insight, thus only making external observations that identified it as a Yellow Gall Insect, without realizing its mutated essence.

Therefore, using conventional means would fail to extract the mutated Yellow Gall Insect, and forcibly attempting it might cause explosive energy that could lead to the rapid demise of the person by damaging their Five Internal Organs and Six Hollow Organs.

This explains Lu Liancheng's sudden intervention earlier. He could watch Liu Yu employ his skills, but once it posed a threat to the patient's life, he wouldn't sit idly by.

Liu Yu now understood the reasoning from Yun Xiao's explanation, but his anger remained unabated; instead, he cast a venomous gaze towards that Yun Xing fellow.

As the princely heir of the Liu Family, Liu Yu had never suffered such public humiliation. Naturally, he wouldn't see himself at fault, believing it all stemmed from Yun Zhi, and vowed to seek revenge once this matter settled.
