Chapter 712: Where Does the Celestial Doctor Come From

Jiang Yushan looked at Xu Bai.

His handsome appearance did not cause any emotional stir within her.

However, the face of "Liu Yihang" immediately flashed into her mind, causing her to hesitate for a moment.

From Liu San, she knew that "Xu Bai" was a clone refined by Liu Yihang. With Liu Ruchen's demise, Liu Yihang was now the Sect Master of the Medicine King Sect.

Her expression softened slightly, and after some hesitation, Jiang Yushan finally nodded slightly.

"Since the Sect Master has said so, then let's give it a try first."

"However, in my early years, I lived in the Boundless Prison and became tainted with an overwhelming aura of malevolence that cannot be removed. Will it truly be alright?"

She frowned slightly, sounding a bit puzzled.

"Given the current demand for the Longevity Pill among Myriad Immortals Alliance cultivators, even if it has minor side effects, it should still be acceptable. After all, one leads to death from old age, while the other only causes slight physical damage. They can discern which is more important," Xu Bai said confidently.

At the same time, he briefly introduced Jiang Yushan to the background of the Soul-Devouring White Mist and the current Myriad Immortals Alliance policy encouraging cultivators to explore it.

"Just now, while flying outside, I noticed those white mist walls piercing through heaven and earth. Devouring lifespans, dividing the world…"

"A thousand years have passed, and such drastic changes have occurred," Jiang Yushan sighed almost imperceptibly.

"Now is the peak time for Longevity Pill sales, and supply cannot meet demand. Elder Liu alone cannot satisfy the need. We hope Elder Jiang can lend a hand," Xu Bai said softly.

"Refining pills… I'll give it a try first," Jiang Yushan nodded in agreement.

A hint of joy appeared on Liu San's face.

Immediately, in the alchemy room of Longevity Valley, ninety-nine Core Formation disciples were summoned, and the Grand Formation of Lifesaving Longevity was set up.

Liu San and Jiang Yushan sat cross-legged in the center of the formation, channeling their Longevity Azure Power into the Medicine King Cauldron, the core of the formation.

As soon as the two streams of power emerged, Xu Bai keenly noticed their differences.

If Liu San's Longevity Azure Power was as vibrant and full of life as spring, then Jiang Yushan's contained a faint wisp of chilling malevolence within its vitality.

And furthermore…

Xu Bai also vaguely found this malevolent aura somewhat familiar.

Xu Bai narrowed his eyes slightly, remaining outwardly calm as he waited for the Longevity Pills to be refined.

With Jiang Yushan's assistance, the formation operated almost three times faster than before. Coupled with Liu San's adept management of the grand formation, it wasn't long before the first batch of Longevity Pills was refined.

Three pills were formed. On the azure-colored, perfectly round pills, an unseasonable wisp of black cloud clung to them, appearing quite unsightly.

Even the natural medicinal fragrance of the longevity-enhancing pills was suppressed.

Even holding the pills in hand, there was no urgent desire to consume them.

"Sect Master, are these pills acceptable?" Jiang Yushan frowned slightly.

Xu Bai did not answer immediately. Instead, he tossed one into his mouth and closed his eyes to perceive its effects.

He wasn't concerned about the increased lifespan but rather focused on the malevolent aura that emerged with the Longevity Azure Power after the pill dissolved in his body, wantonly damaging his physical form.

"As expected…"

"Heavenly Malevolence…"

Xu Bai felt a heavy weight in his heart.

"Elder Jiang, could you please explain in detail what this malevolence is about?" His spiritual energy circulated, slowly repairing the damage caused by the malevolence. Xu Bai opened his eyes and asked.

Jiang Yushan was startled for a moment, then proceeded to explain to Xu Bai.

"In ancient times, cultivators underwent heavenly tribulation to ascend. This tribulation was both a trial and an opportunity. Although there was a risk of death, successful passage would grant the cultivator an infusion of immortal spiritual energy, transforming them into an immortal."

"However, later the path to immortality was severed, and heavenly tribulations no longer appeared. Yet, the killing intent of heaven and earth still needed an outlet, and thus malevolence descended upon the world."

"This was the original source of the malevolence in the Boundless Prison. Later, however, many heinous criminals were imprisoned in the Boundless Prison, intermingling with immeasurable human killing intent."

"Through the interaction of heaven and man, this malevolence became increasingly sinister and troublesome. Even though I have been free from it for decades, constantly cleansing myself with the heart of a healer, it remains difficult to eradicate," Jiang Yushan slowly explained. "My somewhat unique voice is also a result of it."

"However, with such drastic changes occurring in the Xuanhuang Realm, I wonder what the Boundless Prison looks like now," Jiang Yushan said, a hint of wistfulness on her face.

"Heavenly Malevolence, Heavenly Slaughter…" Xu Bai's face showed contemplation.

"Elder Jiang, have you ever seen this person, or a sword filled with malevolence?" As he spoke, Xu Bai conjured images of the Fisherman and the Heavenly Malevolence Sword in the air.

Jiang Yushan stared for a moment, then shook her head: "I have not seen them."

"Then so be it."

This outcome was within Xu Bai's expectations. He waved his hand, dispelling the image of the Fisherman, then said to Jiang Yushan and Liu San: "You two needn't worry. Although the Longevity Pills you jointly refined do indeed cause damage to a cultivator's physical body, the flaws do not overshadow the virtues. If the longevity-extending effect remains unchanged, I believe many people will still scramble to buy them. At most, we'll just lower the price a bit."

Dispelling their concerns, Xu Bai reassured them and told them to continue refining the pills.

"Roughly how many pills should we refine? I'm quite interested in the world after several millennia and want to go out and explore," Jiang Yushan asked directly.

Xu Bai was momentarily speechless.

He looked at Liu San, only to see him gazing at Jiang Yushan with a dazed expression, clearly not opposing her decision.

After a moment of contemplation, Xu Bai said: "Just consume half of the Longevity Pill raw materials within Longevity Valley. Otherwise, hoarding them would be a waste."

Clearly, she did not have a clear quantified understanding of the amount of medicinal ingredients in Longevity Valley. Jiang Yushan nodded, readily agreeing.

"In that case, I'll trouble you two."

Xu Bai smiled slightly and floated away from Longevity Valley.

"At the very least, she won't be able to come out for a year or so."

"However."

The figure of the old Fisherman, Tian Jue, reappeared in Xu Bai's mind.

The malevolence clinging to Jiang Yushan was strikingly similar to the aura around Tian Jue.

Yet, there was a subtle difference.

The distinction was difficult to articulate, but for Li Fan, who had experienced both, it was easy to discern.

If a fitting analogy were to be used, "two samples of seawater with different salt concentrations" might vividly describe the difference between them.

Seemingly similar, yet subtly different, as if…

"They came from two different worlds."

A sharp glint flashed in Xu Bai's eyes.

Jiang Yushan originated from the Boundless Prison and the Medicine King Sect, both of which could be vaguely found in records within the current Xuanhuang Realm.

The conclusion was thus obvious.

Long ago, a faint suspicion had begun to form in his mind.

Tian Yi, Tian Jue, Tian Yu, and the group from Cloudwater Heavenly Palace were very likely not native cultivators of the Xuanhuang Realm.

But rather…

Outsiders.
