Chapter 665: Critically Ill, the Mysterious Immortal of Medicine

Hunyuanzi's injuries worsened drastically, and his entire person aged by several hundred years.

He lay on a giant rock, his aura so faint it was almost imperceptible.

"Senior Hunyuanzi!" The two rushed forward in a hurry.

"How are you?"

Hunyuanzi opened his eyes with difficulty, and upon seeing the two, he revealed a bitter smile.

"I... I am not going to make it..."

"The battle with Xue Tutian consumed too much, plus the backlash from using the Forbidden Technique..."

"I fear I cannot hold on much longer..."

Hearing this, the hearts of Nezha and Zhang Wuji sank to the bottom of a valley.

If even Hunyuanzi died, then who else could stop the out-of-control Lin Xuan?

"Senior, you must hold on," Nezha said hurriedly.

"Only you can save Lin Xuan, save the entire Upper Realm."

Hunyuanzi shook his head, his eyes filled with helplessness.

"I have already done my best..."

"The current Lin Xuan... is already beyond my ability to save..."

"Unless... unless another way can be found..."

Hunyuanzi's condition was more serious than anyone had imagined.

He lay on the giant rock, his whole body looking like a dried corpse.

Originally it was just his outward appearance that had aged, but now even his internal organs had begun to fail.

Nezha cautiously probed his meridians, and his face instantly turned pale.

"How is this possible? Senior's cultivation is dropping?"

Zhang Wuji also checked in a hurry and discovered an even more terrifying fact.

Hunyuanzi's cultivation had already fallen from the early stage of the Great Vehicle Stage to the peak of the Integration Stage.

And the speed of the decline was still accelerating, as if something was devouring his power.

"This is not ordinary cultivation loss," Zhang Wuji said gravely.

"His foundation has suffered irreversible damage."

After observing carefully, Nezha discovered an even more horrific sign.

Hunyuanzi's life essence was rapidly draining away.

Just like a bucket with a hole in it, it was impossible to stop.

"Senior! Senior!" Nezha called out softly, but Hunyuanzi had no reaction.

His breathing was becoming weaker and weaker, and his heartbeat was also gradually slowing down.

If things continued like this, he likely wouldn't last long.

"We must find a way to save him," Zhang Wuji said anxiously.

"Without Senior Hunyuanzi, no one can stop Lin Xuan."

The two began to rummage through the Pills and spiritual materials on their persons.

Various sacred healing medicines were brought out, but the effect was negligible.

Those precious Pills capable of bringing the dead back to life were as useless as sugar beans in front of Hunyuanzi.

"Why is it like this?" Nezha asked, puzzled.

"These Pills were always very effective before."

After thinking carefully, Zhang Wuji reached a terrifying conclusion.

"What Senior is burning is not ordinary cultivation, but his life essence."

"In that battle with Xue Tutian, the price he paid was greater than we imagined."

"Using a Forbidden Technique like Space-Time Annihilation has already damaged his very roots."

Hearing this, Nezha's face became even uglier.

Damage to one's life essence is the hardest to heal.

This involves a cultivator's foundation; once damaged, it is very difficult to recover.

"Then what should we do?" Nezha asked.

"We cannot just watch Senior die."

Just as the two were in despair, an aged voice sounded from behind them.

"Let me take a look."

The two turned around abruptly and saw a white-haired old man standing not far away.

This old man wore simple cloth clothes and leaned on a bamboo staff in his hand.

He looked like an ordinary village farmer, but his eyes flashed with a profound light.

"Who are you?" Nezha asked vigilantly.

At a time like this, any stranger was worth suspecting.

"This old man is Yao Wuji, known as the Immortal of Medicine," the old man said calmly.

"I have lived in seclusion for a thousand years, specializing in the Dao of medicine."

"I can also be considered to have had a brief acquaintance with Hunyuanzi."

Hearing the title 'Immortal of Medicine', a glimmer of hope flashed in the eyes of the two.

The Immortal of Medicine, Yao Wuji, was a legendary existence in the Upper Realm.

It is said to be able to bring the dead back to life and restore one to health.

If it really is him, then Hunyuanzi might still be saved.

"Senior, you must save Senior Hunyuanzi," Nezha requested hurriedly.

"As long as he can be saved, we are willing to pay any price."

Yao Wuji nodded and walked to Hunyuanzi's side.

He extended his withered fingers and gently stroked Hunyuanzi's forehead.

A wisp of faint life force emanated from his fingertips, probing Hunyuanzi's condition.

A moment later, Yao Wuji withdrew his hand, his expression turning grave.

"The situation is more serious than I imagined."

"He not only burned his cultivation, but also depleted his life essence."

"His current state is already that of a lamp whose oil has run dry."

Hearing this, the hearts of Nezha and Zhang Wuji sank to the bottom of the valley.

If even the Medicine Immortal says it is serious, then there is truly no hope.

"Senior, is there really no other way?" Zhang Wuji asked unwillingly.

Yao Wuji pondered for a moment and spoke slowly.

"It is not entirely without a way."

"But it requires two extremely rare Heaven and Earth Treasures."

"Nine-Turn Soul-Returning Grass and Ten-Thousand-Year Blood Lingzhi."

Hearing these two names, the two of them were instantly stunned.

The Nine-Turn Soul-Returning Grass is a legendary divine medicine capable of reshaping life essence.

The Ten-Thousand-Year Blood Lingzhi is an even rarer treasure, possessing the miraculous effect of bringing the dead back to life.

Both of these items are things one can only hope to encounter by chance, not seek out.

Even with money, they cannot be bought; one can only rely on luck to find them.

"Senior, these two items..." Zhang Wuji said with difficulty.

"I know they are hard to find," Yao Wuji sighed.

"The Nine-Turn Soul-Returning Grass only grows in places where Yin and Yang converge."

"The Ten-Thousand-Year Blood Lingzhi requires ten thousand years of time to mature."

"The places in the entire Upper Realm that might have these two items can be counted on one's fingers."

"Then where are they?" Nezha asked hurriedly.

"The Nine-Turn Soul-Returning Grass might be in the Life-Death Valley of the Extreme North Cold Domain," Yao Wuji said.

"That place is where Yin and Yang converge, most suitable for this divine medicine to grow."

"As for the Ten-Thousand-Year Blood Lingzhi, only the forbidden ground of the Blood Demon Sect might have it."

"They have collected Heaven and Earth Treasures for tens of thousands of years; they should have such a thing."

Hearing these two places, the expressions of Nezha and Zhang Wuji became even uglier.

The Life-Death Valley in the Extreme North Cold Domain is one of the most dangerous places in the Upper Realm.

Even going there in peak condition is a nine-deaths-and-one-life situation.

In the current situation, it is even more of a one-way trip.

As for the forbidden ground of the Blood Demon Sect, that goes without saying.

Although the Blood Demon Sect suffered heavy losses, a thin camel is still bigger than a horse.

Their forbidden ground must have heavy defenses; those who trespass will surely die.

"And the most critical thing is time," Yao Wuji continued.

"Hunyuanzi's current state can last at most three more days."

"Beyond this time, even with divine medicine, there will be no way to save him."

Three days!

This news struck the two of them like a bolt from the blue.

It is impossible to travel across half the Upper Realm to seek treasures in three days.

Not to mention that the entire Upper Realm is currently shrouded in the killing Yinying of Lin Xuan.

Who would dare to go out at this time?

"Senior, is there really no other way?" Nezha asked in despair.

"For example, using other medicinal herbs as substitutes, or extending the time?"

Yao Wuji shook his head.
