"Let me take a look," Lin Fan extended his hand, three fingers resting on Liu Qinghui's wrist. A stream of purple spiritual energy flowed in.
The malevolent energy was still present, and much stronger than before, gradually corroding his internal organs.
Calculating the time, over half a month had passed since he first treated Liu Qinghui.
With the illness's progression, his organs would completely fail within three to five days, leading to death.
Lin Fan had originally planned to visit tomorrow, but since Liu Qinghui had come to him, it saved him a lot of trouble.
After the examination, Lin Fan had a question.
This malevolent energy was very strange; it didn't belong to any of the gold, black, or white witchcraft, nor was it spiritual energy.
"Hmm?"
Suddenly, Lin Fan raised his hand.
Because of this malevolent energy, it had actually launched an attack on him.
"Seal!"
Lin Fan let out a low cry and sharply extended his sword fingers.
"Roar!"
A purple dragon phantom appeared, coiling around his arm, and swiftly burrowed into Liu Qinghui's body.
"Purple Dragon Suppresses Evil!" Lin Fan shouted.
"Ah!"
The malevolent energy within Liu Qinghui's body let out a pained scream upon encountering the purple dragon phantom.
Lin Fan gave it no chance, waving his right hand as nine silver lights flashed.
The next moment, nine silver needles appeared on Liu Qinghui's body, each inserted precisely into an acupoint.
The nine silver needles formed a circular formation, tightly imprisoning the malevolent energy within.
Then, Lin Fan crossed his middle and index fingers, sending nine streams of purple dragon phantoms towards the nine silver needles.
The purple dragons roared, winding upwards, coiling above the silver needles.
The dragon heads all aimed at the malevolent energy in the center, completely trapping it.
This was a divine ability Lin Fan had comprehended after refining the dragon horn: Purple Dragon Suppresses Evil!
Originally, this was a formation used in combat, with nine purple dragons sealing nine directions, and he himself positioned above them, capable of trapping peak experts.
Since his primary profession was medicine, he had modified this formation into a method for healing.
The malevolent energy within Liu Qinghui thrashed wildly, attempting to break free.
But the nine purple dragons simultaneously spewed flames, forming an extremely powerful defensive barrier.
"Suppress!"
With a command from Lin Fan, the barrier rapidly shrank and squeezed.
He then extended his sword fingers again, releasing spiritual energy to form a colossal purple sword.
It erupted with dazzling light, shooting up into the sky.
A pillar of purple light shot straight from the medical hall into the heavens, scattering the clouds.
On Liu Qinghui's chest, a twenty-centimeter-long purple light sword stood upright in the center.
Although this sword was embedded in the middle of his chest, it caused him no harm.
Lin Fan swept his right hand across Liu Qinghui's chest, and the nine silver needles vanished instantly.
Then, he drew out the purple light sword.
"Ah!"
Impaled on the tip of the sword was a mass of black malevolent energy.
It had an irregular shape, resembling a pool of black sewage.
"Xiao Fan, what is this?"
Liu Qinghui frowned, no wonder he felt so terrible. Having such a disgusting thing inside his body, who could feel comfortable!
"The malevolent energy has materialized. This is a very skillful technique, likely not achievable by ordinary experts."
Lin Fan clicked his tongue in amazement. This malevolent energy had no energy fluctuations, yet its malevolent intent was incredibly potent.
Malevolent energy was different from witchcraft or spiritual energy. It was formed by refining malevolent thoughts and was usually formless, merely a field of energy.
Only powerful experts, or those possessing powerful magical artifacts, could refine malevolent energy to harm others.
Just like the male lead in the Mì Mi production crew, he had refined malevolent energy into a gaseous form, but it was extremely weak, only capable of harming ordinary people.
Upon encountering Lin Fan's purple spiritual energy, it surrendered without even resisting.
This was because the male lead's own strength was low, and he lacked any powerful artifacts.
However, the malevolent energy before him was different. Not only had it materialized, but it also left no residual aura, making it impossible for Lin Fan to identify the true culprit.
"Can you tell what it is?" Liu Qinghui asked.
Lin Fan shook his head and muttered to himself, "Could it be innate malevolent energy?"
He was shocked. If this were innate malevolent energy, then Liu Qinghui's villa must be incredibly unlucky!
"Old Man Liu, have you been to any extremely ominous places before?" Lin Fan asked.
Liu Qinghui pondered for a moment, then slapped his thigh. "I remember! A while ago, I attended a gathering with my old comrades, and we visited a battlefield where we once defended against foreign invaders."
Lin Fan's eyebrows rose. That explained it.
What kind of place was a battlefield? During wartime, tens of thousands of people died daily, causing malevolent energy to accumulate and naturally form; it was perfectly normal.
Lin Fan had read some records in the "Supreme Equilibrium Canon." After large-scale wars between mortals, the battlefields would be shattered.
At that time, kind cultivators would specifically go to places after battles to purify the malevolent energy.
Otherwise, over years of accumulation, extremely terrifying Yin-Sha lands would form, and anyone passing by would have malevolent energy enter their bodies.
Young people would be fine; as long as they didn't linger too long, it wouldn't matter.
But Liu Qinghui was an old man in his seventies or eighties. No matter how powerful he was in his youth, in his later years, his body's Yang energy would significantly decrease, making him most susceptible to the life-threatening effects of malevolent energy.
"Xiao Fan, what are you thinking about?"
Seeing him lost in thought, Liu Qinghui couldn't help but ask.
Lin Fan snapped back to attention. "Nothing. Can you tell me where the battlefield you visited is?"
Liu Qinghui pointed west. "It's on the border over there. That battle was incredibly fierce, with countless casualties!"
"The broken pot that you took was found by my granddaughter there."
"Hiss~"
Lin Fan gasped.
Since the broken pot was found there, the owner, that powerful being who treated a hundred-year-old ginseng and silver-heart grass like trash, likely cultivated in this area.
Lin Fan felt it was necessary to go and take a look.
To see what treasures that powerful being from back then might have left behind.
If his strength allowed, he would also purify the malevolent energy there to prevent further harm to others.
"Xiao Fan, tell me the truth, who exactly are you?"
Liu Qinghui hesitated for a long time before asking.
Lin Fan rolled his eyes. "Just a doctor, my medical skills were all learned from my grandfather."
He didn't know Liu Qinghui well enough to tell the truth.
"Is your grandfather Senior Lin Sheng?"
Liu Qinghui's old eyes twinkled with keen light, as if recalling something.
"You know my grandfather?"
Lin Fan was surprised. This old man was in his seventies or eighties, why did he call his grandfather "Senior"?
Based on his age, his grandfather, if still alive, would be at most in his early sixties.
"More than just knowing him, my old life was saved by Senior Lin!"
Liu Qinghui clasped Lin Fan's hand. "Fate is truly a wondrous thing! Back then, on the battlefield, I was surrounded by the enemy and fighting for my life, prepared to die for my country."
"At that very moment, Senior Lin descended from the sky and annihilated the entire enemy army with his bare hands, as if a war god had descended!"
"He left after the deed, but his great military merit was attributed to me."
"I never expected that fifty years later, his grandson would save my life again."
Lin Fan was stunned upon hearing this.
After composing himself, he asked, "What did you see my grandfather look like? How old was he?"
Liu Qinghui looked at the ceiling, recalling, "He was lean and sinewy. He looked to be in his late forties, wearing a golden witch robe, so he must have been from the Golden Witch Sect."
