Shen Qiang's words not only failed to relax Bai Jiao's tightly furrowed brows but instead increased her disgust.

However, at this moment, Shen Qiang felt somewhat excited.

Once again, it was proven that Shen Qiang's method was effective. By injecting True Yuan and stimulating more Mycobacterium tuberculosis to enter the enemy's body, the massive number of bacterial colonies accelerated the infection. Not only was it feasible, but it was also highly effective.

When the opponent's cultivation was within the Nascent Soul Stage, if Shen Qiang fully stimulated the tuberculosis bacteria, then in at most three minutes, the opponent would be coughing up large amounts of blood.

The damage this caused in itself was not fatal, but the psychological pressure it put on the opponent was, far greater than pneumonia, influenza, or intestinal flora imbalance could ever compare.

Moreover, this was just a single strain of bacterial infection.

If Shen Qiang concurrently used influenza, tuberculosis, pneumonia, and Thermophilic Streptococcus, then opponents below the Nascent Soul Stage would be essentially incapacitated upon infection.

As for those above the Nascent Soul Stage, there has been no test yet, so it's hard to say.

But if Shen Qiang used Star Moon's Protection for invisibility while infecting with these bacterial strains, as long as the enemy's body was still human, falling was just a matter of time.

"Sure enough, after obtaining the Mycobacterium tuberculosis, the psychological pressure it puts on the enemy is far too great. If it were just a cold or just a stomach upset, he wouldn't leave the field, but now, as soon as coughing blood occurs, they immediately lose all their composure and their minds become completely disordered. If this happened during combat, their death is certain."

Shen Qiang's eyes were bright and clear.

The trade fair continued.

At this time, seeing that Master Tianji and Li Yongjie had already left, the several elders with him not only did not show any hostility towards Shen Qiang, but their gaze became sharp and clear.

"Shen Xiao You has quite the skills. I've studied various poisons for decades and still couldn't see how you made your move. Ah, indeed, the new generation replaces the old, and it's undeniable that I'm getting old."

"Yes, Shen Xiao You's skill is innate; it's completely imperceptible. Otherwise, given Master Tianji's temper and personality, he would've lashed out and attacked long ago."

"Truly formidable; with this undetectable poison skill, there's nowhere in this vast world Shen Xiao You can't go."

In the midst of the elders' praises,

Shen Qiang slightly smiled.

Traditional poisoning methods are nothing more than using poisons to intoxicate the enemy.

But whether it's through deployment or volatilization,

There are movements, traces, and scents.

But the Plague Source is different.

What it releases are odorless and tasteless pathogens.

All Shen Qiang needed to do was simply issue an order and lend it some True Qi.

Without having to lift a finger, everyone within a twenty-meter radius or a forty-meter diameter circular area around Shen Qiang was under the cover of the Plague Source.

Even if they held their breath,

Any minor cut on their bodies would still be unable to resist the invasion of the Mycobacterium tuberculosis.

"Without evidence, you shouldn't speak carelessly. I have never attacked anyone. As a doctor, I simply observed that he was about to fall ill within five minutes," Shen Qiang said with a faint smile.

The crowd was stunned, then their eyes flashed with a mix of fear and amusement as they looked at Shen Qiang.

"We old fellows have only done two things in our lives, one is cultivation, the other is alchemy. If we really did anything else, it would surely be related to medical skill. Although we're not masters, we're quite familiar with Huaxia's medical procedures of looking, listening, questioning, and taking the pulse. When we looked at Li Yongjie just now, he was very robust."

"Hmm, indeed, whether someone is sick or not can be discerned from their complexion."

Amid the knowing looks from the many elders as if to say, "You don't need to pretend, we all know you had a hand in it," Bai Jiao's beautiful eyes widened in shock, mixed with some surprise as she looked at Shen Qiang. Just as Shen Qiang thought she might get angry, she burst into laughter and then smiled, "I knew it, you crude fellow, you're definitely not some righteous gentleman who would turn the other cheek."

Shen Qiang smiled slightly and said, "Think whatever you want, but I won't admit to it."

Bai Jiao's eyes crinkled with laughter.

She whispered and started making casual conversation with Shen Qiang, paying no attention to the trading convention whatsoever.

However, for Shen Qiang, although his attention was indeed focused on the trading convention.

Most of the materials, elixir pills, and some heavenly materials and earthly treasures that appeared at the convention were either only usable after Shen Qiang reached the Nascent Soul Stage or had readily available substitutes. Otherwise, they were simply defective or failed products.

Moreover, the strangest thing lay herein.

The so-called top-grade treasures, which were recognized as elixir pills by the Cultivation World.

Upon inspecting them with the Observation Skill and comparing them to the Medical Saint Inheritance,

they were all unqualified.

Even those elixir pills produced by renowned figures in the Cultivation World still had various flaws.

They simply didn't meet the qualification standards for elixir pills outlined in the Medical Saint Inheritance.

The only one that was barely acceptable was a Qingling Pill. The conclusion after assessing it with the Observation Skill was that it was a flawed Qingling Pill.

This pill came from Medicine King Valley.

Based on the method of refinement and its appearance, it was the only item at the entire trading convention that could truly be considered a pill.

However, Qingling Pills neither enhanced cultivation nor could they be life-saving in critical moments.

Their purpose was to treat infertility in women.

So, this item was essentially useless.

Because modern medicine has already advanced significantly, and human assisted reproduction technology has matured.

In vitro fertilization, embryo transfer, these are no longer issues.

In the black market, all sorts of surrogate services, egg and sperm donations are readily available; with money, one can have whatever they desire.

Therefore, the Qingling Pill would only be purchased by women who lacked eggs. By taking it, they could repair their damaged ovaries and thus gain the ability to conceive.

But clearly, the number of such women would not be high.

Because the majority, under such circumstances, would directly opt for buying eggs and hiring a surrogate instead.

As expected, the Qingling Pill, the only item that was barely considered a pill, eventually sold for 3 million yuan.

Definitely not worth much money.

The items that followed in the auction, one more boring than the last, were fiercely contested by others. Yet to Shen Qiang, they were merely garbage.

Naturally, he had no interest in making an offer.

So, just like Bai Jiao, he made idle small talk without much involvement.

Fortunately, Bai Jiao was pretty with a discerning eye, and conversing with her was not boring.

Soon, the trading convention was drawing to a close when Bai Jiao's sturdy, bespectacled female assistant came over and whispered something in Bai Jiao's ear.

Bai Jiao stood up immediately and gave Shen Qiang a slight smile, "Excuse me for a moment."

After that, she gracefully walked up to the auction stage, and after taking over from the auctioneer, she smiled sweetly and said, "Thank you all for coming to Cheng Xinyi's Provincial City store. The next item for auction is the ultimate treasure of this convention, the Pei Yuan Pill! It comes from a senior who does not wish to reveal his identity."

Everyone was taken aback and immediately started buzzing with conversation.

"The Pei Yuan Pill? Didn't they already sell one at the start?"

"Haha, interesting, is Pei Yuan Pill also considered an ultimate treasure?"

Among the murmurs of the crowd, Bai Jiao smiled sweetly, "Although it is only a Pei Yuan Pill, its elixir grade has surpassed legend, reaching the Divine Grade Red Pearl level! Looking across the Cultivation World, none can compare!"
