Chapter 800: Using the City as Furnace

Not only was Sun Gongming shocked, but even Gu Tengfeng, Gong Cheng, and the others stared at Ling Feng in disbelief. After going through so much trouble to borrow these precious herbs, they were just going to burn them on the spot?

"Ling Feng, did you misspeak? Burn them right here?"

Gu Tengfeng fixed his gaze on Ling Feng, seeking confirmation.

"No mistake. We burn them right here." Ling Feng nodded with a faint smile.

"Young friend Ling, this is no time for jokes," Sun Gongming said with a pained expression. If they burned all these herbs, where would they ever borrow replacements?

Ling Feng raised an eyebrow. "Who said burning herbs renders them useless? Physician Jin, you must be familiar with smoke purification therapy, correct?"

"Smoke purification?"

Jin Weide, standing behind Sun Gongming, blinked rapidly. Among those present, aside from Ling Feng, he was the most accomplished physician.

After stroking his chin in thought, Jin Weide's eyes suddenly brightened. "Young Hero Ling, while smoke purification therapy has historical precedent, I've read that simply burning herbs preserves less than one percent of their medicinal properties. Even if we direct the smoke into the city, it wouldn't have any therapeutic effect."

"Physician Jin is quite right." Ling Feng nodded.

"Then why burn the Moonshadow Silken Herbs?"

Gu Tengfeng and the others were more confused than ever, like monks scratching their heads in bewilderment.

"Ordinary herbal smoke wouldn't work, but with special techniques, we can extract and concentrate the spiritual essence within the herbs into the smoke. When the Blood Spirit Corpses inhale it, neutralizing the Blood Corpse Poison will be effortless."

A faint smile played on Ling Feng's lips. Even if they refined the herbs into medicinal pills, they'd still need manpower to enter the city and administer them to each Blood Spirit Corpse—a laborious and dangerous process.

Ling Feng's smoke purification method was nothing short of ingenious.

"What special techniques?"

Everyone stared at Ling Feng in astonishment.

"Using the city itself as a furnace to refine medicine!"

Ling Feng smiled mysteriously. "This is why I asked the general to prepare soldiers with wind and fire attributes. If you trust me, have the troops follow my instructions from here on."

Sun Gongming had no other options left—he had to believe in Ling Feng now. Gritting his teeth, he said in a low voice, "All troops, heed Young Hero Ling's commands without question!"

"Yes, sir!"

The soldiers responded in unison, not daring to slack off.

Ling Feng then divided the soldiers into eight groups according to their wind or fire attributes, positioning them around the city in an eight-trigram formation. Fire attribute martial artists were tasked with burning the Moonshadow Silken Herbs, while wind attribute cultivators controlled the airflow to direct the smoke into the city.

Meanwhile, Ling Feng hovered at the center of Yanbao City, forming hand seals to execute the Nine Refinements of Mystic Fire technique.

"Light the fires!"

Ling Feng's voice boomed across the city, amplified by his martial prowess. At each of the eight positions, fire attribute martial artists ignited the herbs simultaneously. Thick smoke billowed upward, carrying a sweet, fragrant aroma.

"Direct the winds!"

As smoke rose from all directions, Ling Feng gave the next order. Wind attribute cultivators channeled their true essence, creating gentle breezes to push the smoke into the city.

Then, Ling Feng's body blazed with fiery light, transforming him into what seemed like a miniature sun. He gathered all the smoke toward himself, refining it as though it were ingredients in an alchemical process.

With a few simple hand seals, ordinary smoke became medicinal vapor capable of detoxification. Of course, this also required additional medicinal solutions—Ling Feng used his own body as a medium to transform the smoke before carefully regulating its dispersal by coordinating the soldiers' control of flames and wind speed.

(Author's note: This process resembles a catalytic reaction in chemistry. The medicinal solutions in Ling Feng's possession acted as catalysts—they didn't participate in the chemical changes themselves, so large quantities weren't necessary.)

Before long, the transformed medicinal vapor spread throughout Yanbao City, settling over every inch of ground.

The Blood Spirit Corpses below grew restless at first when they saw flames and smoke everywhere. But upon inhaling the medicinal vapor, their dull eyes gradually regained clarity.

Fifteen minutes passed!

Then thirty!

After a full hour, the ordinary citizens began awakening one after another. They looked around at each other, then burst into tears—their recent experiences had been nothing short of a living nightmare!

"It worked! It actually worked!"

On the city walls, Sun Gongming, Jin Weide, and the others laughed heartily as they watched the Blood Spirit Corpses return to normal. Ling Feng's method was absolutely brilliant!

"Brother Feng truly lives up to his reputation! From today onward, you're my idol!"

Lin Mochen gave Ling Feng a thumbs-up, his face filled with nothing but worship.

"Big Brother is so smart! I could never think of such a good solution in a million years!"

Jiang Xiaofan scratched his head with a simple, honest laugh.

"

Hahaha...

" The East Court Sword Team members shared knowing smiles. Even the usually cold Li Bufan wore a faint grin.

Gong Cheng shook his head with a smile. "Xiaofan, this isn't just about intelligence. Without sufficient medical knowledge, no amount of cleverness could devise this method. In short, it never hurts to read more books."

"

Ah?

" Jiang Xiaofan's face fell. "Then forget it. I'd rather practice with swords!"

Ling Feng descended from the sky, his face pale from exhaustion. Using an entire city as an alchemical furnace and controlling the entire process had pushed him to his limits.

This "alchemy" method was likely unprecedented in history—a technique pioneered by Ling Feng himself.

"Young friend Ling, you've worked hard."

Sun Gongming stepped forward to support Ling Feng, transferring a stream of pure elemental force into him. Ling Feng's complexion improved slightly.

"It's nothing." Ling Feng smiled faintly. "Being my first attempt, I used excessive force in some areas initially. But with more practice, it'll become smoother."

Fifteen more cities awaited this treatment. Applying the same method should quickly resolve the Blood Spirit Corpse crisis.

"Physician Jin, how much of my flame and smoke control technique did you understand?" Ling Feng turned to Jin Weide with a faint smile.

"I'm afraid I only grasped thirty to forty percent."

Jin Weide sighed with a wry smile.

"Then after observing a few more times, Physician Jin should master this method."

Ling Feng pursed his lips. Jin Weide's comprehension was somewhat lacking, but to improve efficiency and prevent the Blood God Cult from causing more trouble, they'd need to teach this technique to as many physicians as possible.

After all, the mastermind—the Blood Sword Heavenly Lord Li Qingling—had ultimately escaped.

He could only hope the other cities had military physicians with slightly better aptitude.
