"Elder Guan, did something happen to the Dean?"

Even before Guan Rufeng spoke up, Qian Sanyuan impatiently asked because the Dean of the Heavenly Hospital was the top leader responsible for President Lu Yanji's closed-door cultivation affairs.

Since the time President Lu Yanji returned from Xuanyin Hall, he began his closed-door cultivation, stating that he would not emerge unless he broke through to the Heavenly Realm, perhaps pressured by that Holy Grade Heavenly Spirit.

Lu Yanji knew that if he didn't break through to the Heavenly Realm and allowed that Heavenly Spirit to return to its peak state, it might become unrivaled on the entire Tenglong Continent, causing endless suffering.

But what Lu Yanji did not expect was that during his closed-door cultivation, a Strange Spirit had already begun to ravage the Eastern Domain of Tenglong Continent, even rendering Impermanence Island wiped out.

If not for a young man named Yun Xiao emerging seemingly out of nowhere, this Strange Spirit's momentum would have undoubtedly swept the entire Tenglong Continent, and by the time he completed his breakthrough, all he would see was a devastated continent.

For such a long time, nothing unusual had happened with Lu Yanji; everything progressed step by step. Qian Sanyuan and Qingmu Wu still had high confidence in the President.

They never imagined that one day the President's closed-door cultivation would encounter a change. Although the cause was unknown, Guan Rufeng's expression had already told them something.

"Well... I'm not quite sure myself. Vice President, let's go and take a look together!"

Who would have thought that as Qian Sanyuan urgently questioned, Guan Rufeng didn't give a direct answer. His face remained anxious with a hint of confusion, and without waiting for Qian or Qing to speak further, he turned and led the way.

"Yun Xiao, you should come with us to take a look!"

Just as Qian Sanyuan was about to follow Guan Rufeng out of the courtyard, he spotted a roughly dressed young man out of the corner of his eye and suddenly felt moved, immediately extending an invitation.

Perhaps, in Qian Sanyuan's heart, he no longer saw Yun Xiao as merely part of the younger generation, especially after witnessing the amazing methods he used to help Liu Mo, Ling Wan, and others find their breakthrough opportunities.

Qian Sanyuan could see that after Yun Xiao broke through to the Middle Stage of Floating Life Realm, his Meridian Refining Technique might not be inferior, and in many ways, he might even outshine himself.

Lu Yanji was a middle-level Heaven Rank Meridian Refining Master. Even he encountered some issues, so Qian Sanyuan doubted his own Meridian Refining methods could help. It might be better to involve this remarkable young man.

"Hmm!"

Yun Xiao naturally wouldn't refuse Qian Sanyuan's proposal. He knew that back in Extreme Yin City, Lu Yanji had saved his life, so both sentimentally and reasonably, he couldn't ignore this.

Moreover, if anything were to happen to Lu Yanji, this vast Lianyun Mountain would be left with only Qian Sanyuan and Qingmu Wu, both Late-stage Floating Life Realm powerhouses, along with Guan Rufeng, who had just broken through to Early Stage. Overall strength would undoubtedly plummet.

All these years, the Meridian Refining Master Guild was revered not just by their Meridian Refining Technique but primarily supported by Lu Yanji alone in terms of Meridian Qi Cultivation Combat Power.

Lose this pinnacle Lingyun Realm figure, the guild's strength could not compare to other first-class forces like Demons Mountain and Ling Kong Island.

After all, within the Double Islands and Double Mountains, there were Lingyun Realm powerhouses. Lu Yanji was indeed the pillar of the guild and could not tilt even slightly.

At this point, Yun Xiao, led by the three elders, arrived at a black-green interwoven grand hall, seemingly the location where President was in seclusion.

"Huh?"

Upon seeing the hall, Yun Xiao's powerful Power of Soul sensed a peculiar aura, causing him to exclaim softly with some guesses forming in his mind.

"What's going on?"

Beside him, Qian Sanyuan and Qingmu Wu also sensed that peculiar aura. As they approached, they noticed some unusual phenomena with the black-green hall.

The grand hall, originally in alternating black and green colors, now had a thick layer of green mist swirling on the left and a rising black mist on the right.

At the intersection of black and green mist, there were signs of mutual infiltration, looking very mystical. Yun Xiao wasn't aware that prior to this, the periphery of the hall hadn't had these black and green mists.

"It seems to be emanating from within the hall. Could it be that President..."

Qingmu Wu's gaze showed a trace of fear as he muttered while staring at the green mist, although he didn't finish the sentence, his deduction was clear.

"Hmm, the green mist should be the 'Yuan Ming Spider Poison' that President once refined, but the black mist, I'm not too clear about!"

The one speaking this time was Guan Rufeng, the Director of Heavenly Hospital. Perhaps the reason he reported to Qian Sanyuan immediately was that he discovered something amiss.

The elders of the Meridian Refining Master Association knew that the President in the hall wasn't a simple Medical Pulse Master or Poison Vein Master, but rather a master of both.

Moreover, Lu Yanji's talent was extraordinary, and his proficiency in both Medical Pulse Technique and Poison Meridian Skill was exceptional, reaching the middle-level Heaven Rank. Truly, he was a rare genius in Meridian Refining on the Tenglong Continent.

As for the "Yuan Ming Spider Poison" mentioned by Guan Rufeng, it was a potent poison refined by Lu Yanji from a fortuitous encounter.

The Yuan Ming Spider was an extremely rare and highly poisonous Pulse Demon on the Tenglong Continent. It was said that this venomous spider-shaped Pulse Demon solely dwelled in the deepest parts of mountain ranges.

Each Yuan Ming Spider had its own territory, and if any human or Pulse Demon trespassed, they would be poisoned to death, without exception.

No one knew how Lu Yanji found the Yuan Ming Spider or refined its spider venom into his innate poison, but such a venomous method was what supported his long-standing dominance at the top of the Heavenly List.

The Yuan Ming Spider Poison hadn't caused any backlash against Lu Yanji, instead enhancing his combat power significantly. Many elders of Lianyun Mountain believed the President must have a way to counter the spider poison.

However, now that the Yuan Ming Spider Poison formed a green fog enveloping the hall, it was likely a sign that the President couldn't control it.

The terror of the Yuan Ming Spider Poison needed no further explanation. If uncontrolled, not just Lu Yanji but even many cultivators of the Meridian Refining Master Association might be lethally poisoned.

"In that case, the black fog should be some force used by the President to suppress the Yuan Ming Spider Poison?"

Upon these thoughts, Qian Sanyuan quickly responded and pointed towards the black fog on the right side of the hall, speaking with grave seriousness.

After these words, the two beside him slowly nodded, as the black and green fog seemed to possess a subtle suppressive force, clearly applied intentionally.

Although none of the three sensed what the black fog truly was, they knew the President's techniques were beyond their comprehension, and he might indeed suppress the Yuan Ming Spider Poison.

"Black Wood Qi!"

As the three major figures of Lianyun Mountain were at a loss, a low voice came from nearby, drawing their puzzled eyes to the rough-clothed youth, Yun Xiao.

"What Qi?"

Upon hearing this unfamiliar term, Qian Sanyuan and the two others showed a hint of confusion and instinctively asked, their voices filled with deep uncertainty.

"I said the black fog is called Black Wood Qi, a special force used to neutralize potent toxins!"

Yun Xiao didn't turn around, his gaze still fixed on the black and green mists, but his explanation cleared their confusion.

At this point, Qian Sanyuan and the others no longer cared how Yun Xiao knew of Black Wood Qi; they just wanted to know if it could suppress the Yuan Ming Spider Poison and keep the President safe.

"If I'm not mistaken, the cultivation technique of our President should be the 'Black Wood Poison Technique'?"

Knowing what the few behind him were thinking, Yun Xiao's eyes glinted slightly as he spoke softly, though his tone held a sense of certainty, as if he was fully confident.

"How do you know?"

Guan Rufeng, who had just quelled his shock at Yun Xiao's breakthrough to the middle-stage Floating Life Realm, was directly startled by the latter's words, indirectly answering Yun Xiao's question.

Even Qian Sanyuan and Qingmu Wu beside him looked at the young man with faces of astonishment, finding him increasingly unfathomable.

Indeed, the President's cultivation technique was known as the Black Wood Poison Technique, but it was a high-level Heavenly technique, one that others couldn't cultivate.

Only uniquely gifted individuals like Lu Yanji, skilled in both medical and poison cultivation, could cultivate the Black Wood Poison Technique to small success, as it was tailored for cultivators with dual mastery.

Although Lu Yanji hadn't reached the Heavenly Realm's high-level to cultivate it to great success, it was the formidable nature of this technique that allowed him to dominate the Tenglong Continent's major forces and secure his place at the top of the Heavenly List.

However, despite the technique's apparent power, it had many downsides; perhaps Lu Yanji himself knew them but outsiders like Qian Sanyuan and Qingmu Wu did not.

Yet none of this escaped Yun Xiao, who was a Long Xiao Battle God in a past life, recognizing that his chance to repay Lu Yanji's life-saving grace had finally arrived.
