As Liu Yu spoke, everyone knew it was that guy named Yun Xing talking again, and they all turned their heads with interest, wanting to know what he was going to say this time.

"Hehe, I just want to ask, did Your Excellency understand the illness of this patient in front of you this time?"

Yun Xiao wasn't bothered by Liu Yu's threatening words at all, but as soon as he spoke, everyone couldn't help but recall what had happened earlier, and a strange feeling rose in their hearts once more.

Earlier, Yun Xing had identified the mutated yellow bile worm inside the patient and had spoken up suddenly, but now, Liu Yu hadn't done anything yet. Could it be that he saw something amiss again?

"It's just a guy rendered comatose by medicinal poisoning, what's so special about it?"

It must be said that Liu Yu is indeed a genuine Spirit-grade Advanced Pulse Refining Master. He had only just begun but was also able to discern the patient's condition, and this statement seemed to reclaim some of the dignity that belonged to a meridian refining genius.

Upon hearing this, a few people surrounding the patient showed a trace of realization on their faces. Many among them were Spirit-grade mid-and-low-level Pulse Refining Masters, albeit with some doubts in their hearts, they dared not be completely confident.

The so-called medicinal poisoning spoken by Liu Yu wasn't truly a deadly poison but a special substance produced when a cultivator consumed an elixir with attributes that didn't match, hence causing the issue.

It is said that medicine is three parts poison; this saying isn't frivolous. Even elixirs refined by Medical Pulse Masters can't be consumed indiscriminately. Carelessness might cost one's life.

This phenomenon is remarkably similar to the Dragon Tree Spirit Little Dragon's "One Thought to Transform Myriad Poisons." Once these so-called medicinal poisons settle in the body, they can severely disrupt physiological functions, resulting in permanent comas like the person in front of them.

In fact, clearing medicinal poisons is a rather laborious task. First, you must locate the medicament's position, second, during the clearing process, any misstep might harm the patient's body, worsening the situation.

However, this was the selection examination site for Refining Cloud Mountain disciples. Although it was said earlier that curing the person would be considered a passing, if Liu Yu found the right method and cleared a bit of the residual medicinal poison, it would be considered a reluctant pass.

Everyone understood this logic, yet they couldn't comprehend why Yun Xing would speak out to stop Liu Yu at this moment. Did he see something different from what Liu Yu did?

"Medicinal poison?"

As many people nodded slightly, Yun Xiao responded strangely and then said, "That's not wrong per se, but can you guarantee to expel the medicinal poison from his body?"

"Hmph!"

This time, Liu Yu didn't respond to Yun Xiao's words, believing the lad merely intended to mess with him. A moment later, an extremely strong invisible force burst from the center of Liu Yu's eyebrows, precisely his Spirit-grade Advanced soul.

With this powerful soul, a streak of white light flashed between Liu Yu's fingers, and immediately a trace of blazing heat swirled around him. Everyone knew that at this moment, Liu Yu was certainly summoning his Ancestral Vein Fire.

Regarding the method of expelling medicinal poison from a patient's body, more than a few people were knowledgeable. Although there were various methods, Liu Yu was undoubtedly using the most common one now.

Which was to use his Ancestral Vein Fire to enter the patient's body and, together with his formidable power of soul, gradually burn away the medicinal poison inside the patient.

During this process, the patient suffering from medicinal poisoning would undoubtedly endure immense pain. The external Ancestral Vein Fire not only had to evaporate the medicinal poison inside him but might also touch his internal meridians and organs, potentially leading to death due to carelessness.

"Pfft!"

As Liu Yu's Ancestral Vein Fire entered the patient's body, shortly after, the latter spewed a mouthful of fresh blood, laced with a streak of pitch black, making everyone understand something.

"Ah, young people!"

Seeing this, everyone believed Liu Yu's technique was taking effect, while the guy named Yun Xing shook his head and remained unconvinced. However, at this moment, no one else voiced a disturbance.

Even the Chairman Lu Liancheng and others in the head seats sat unmoving, seeming as if they hadn't noticed anything amiss. This method of resolving medicinal poison was indeed considered standard.

As time passed, the arrogance on Liu Yu's face grew a few shades stronger, as he suddenly realized that expelling the medicinal poison this time seemed not to consume much time, possibly eradicating the patient's internal medicinal poison entirely in front of everyone.

Liu Yu had a strong confidence that this time he could certainly win back his stance and regain the face he just lost, proving that the title of Lushan City's top meridian refining genius wasn't for nothing.

"Pfft! Pfft! Pfft!"

However, just as the thought crossed Liu Yu's mind, the patient in front of him suddenly showed a change, vomiting three mouthfuls of black blood in succession, suggesting that something might be amiss.

This indeed seemed like the patient was expelling the residual poison from his body, but after the three mouthfuls of blood, the patient's breath was almost imperceptible, as if he might die any moment.

As he sensed the patient's breath growing weaker, the arrogance on Liu Yu's face instantly vanished, replaced by a shadow of gloom, for he finally realized he had made some mistakes.

When expelling medicine poison, vomiting a few mouthfuls of black blood is typically no cause for concern and can even indicate that the poison is gradually being driven out.

But usually, after vomiting black blood, the patient's breath should grow stronger as the toxicity is being expelled from the body, naturally improving health; it shouldn't be growing weaker like now.

After all, Liu Yu is a bona fide Spirit-grade Advanced Pulse Refining Master. Upon discovering this situation, he had already stopped his Ancestral Vein Fire, and then from his Waist Storage, pulled out a round elixir, stuffing it into the mouth of the patient in front of him.

This is an elixir Liu Yu himself refined to greatly supplement Qi and blood. Although it's a consumable elixir, it has also reached the Spirit-grade Advanced level, indicating his high regard for this assessment.

In Liu Yu's opinion, it's not his method that was wrong, but simply inattentiveness, having overlooked the patient's physical condition. Such an intense detoxification process made it natural for this person's frail physique to be unable to withstand it.

And this Qi and blood-replenishing elixir should easily salvage the situation; as long as he can ensure the patient doesn't die today, Liu Yu still has a chance.

"Tsk tsk, giving him a Qi Boosting Pill at this time, are you in a hurry for him to die faster?"

Unexpectedly, just as Liu Yu performed the action, a familiar voice followed, and at this moment, he had already sent the Qi Boosting Pill into the patient's abdomen using a special technique.

"Nonsense, distracting me!"

Liu Yu didn't respond to Yun Xiao's words; having cultivated the Meridian Refining Technique to the Spirit-grade Advanced level, he naturally possessed a steadfast heart, and would certainly not be shaken by mere words.

But this wasn't something unchanged by Liu Yu's steadiness. In terms of understanding worldly ailments, even Lu Liancheng, the Branch Leader of the Lu Mountain City Meridian Refining Master Guild, probably couldn't compare with Yun Xiao, let alone the Spirit-grade Advanced Pulse Refining Master, Liu Yu.

Poof!

Thus, in the next moment, when Liu Yu fed the patient the Qi Boosting Pill, the latter's face initially showed a flush of color, only to then spurt out a mouthful of crimson blood again.

Whoosh!

At this moment, a gusting sound suddenly rang out, followed by a blur before everyone's eyes, as an elder figure appeared on the other side of the wooden platform, none other than Lu Liancheng, the Chairman of the Meridian Refining Master Guild.

However, Lu Liancheng's face was also somber at the moment, seemingly something had slipped from his control, even making the originally calm him unable to sit still.

"What's happened to Chairman Liancheng? Could it be that the patient indeed has issues?"

Seeing Lu Liancheng's actions, many had thoughts, considering this was the Meridian Refining Master Guild. His sudden action indicated something was indeed wrong.

If Liu Yu's previous approach hadn't been wrong, Lu Liancheng wouldn't be acting this way; if this assessment led to a patient's death, the Meridian Refining Master Guild could not escape blame.

"Move aside!"

Seeing Liu Yu's hand still resting on the patient, Lu Liancheng sternly ordered, causing the latter to shiver and finally retreat a few steps with a pale face.

Even if Liu Yu's background was notable with the support of the Liu Family, in front of this Meridian Refining Master Guild Chairman, he dared not show the slightest defiance.

Moreover, Liu Yu vaguely considered some matters—was his move really wrong this time? Yet, there was indeed residual poison in the patient's body, or perhaps his technique was flawed?

While Liu Yu was utterly puzzled, Lu Liancheng who rushed forward didn't spare him the slightest attention. He saw Lu Liancheng's withered old hands flying, consecutively pointing at over a dozen acupuncture points between the patient's chest and abdomen in a swift, breathtaking manner.

"No wonder he is an Earth Rank Middle Level Meridian Master, though this method… might not be of much use!"

Already sensing Lu Liancheng's power of soul, Yun Xiao first murmured in admiration, then lightly shook his head; with his knowledge, he naturally knew what this Guild Branch Leader intended, but the final outcome might not be desirable.
