"Friend, aren't you being too overbearing?"

A middle-aged man, unhappy with the bullish brute's unreasonable manner, had to raise his head to see the brute's face.

The brute was at least 2.2 meters tall, appearing to have practiced some special Martial Arts Divine Powers, resulting in robust vitality and towering size.

As for his power, he had clearly reached the Late Bone Forger Realm, even the peak was not far away.

With this strength, he was definitively among the top-ranking human mutants.

"What? You have a problem with that?"

The brute ferociously glared at the middle-aged man, his attitude unbearably domineering.

The man was intimidated by this momentum, retracting his neck in fright and hurriedly stepping back into the crowd.

"Coward!"

The brute sneered, loudly insulting him without restraint.

The middle-aged man, however, did not dare to utter a word.

"Hmpf, at least you know your place!"

The brute no longer paid any attention to the middle-aged man. He turned back to Xiao Mu's stall to look at the Flying Sword Fragment.

"I'll take this Flying Sword Fragment."

His attitude was still filled with an overwhelming dominance.

"Twenty energy fruits, cash and carry."

Xiao Mu quoted the price without purposefully inflating it.

Despite despising the brute's actions, he wouldn't mix business with personal grudges and refuse to sell the energy fruit to him.

"Twenty energy fruits?"

The brute frowned, his deep voice echoing his continuing dominance, "I don't have any energy fruits, how about a trade for something else?"

"Sorry, I only accept energy fruits."

Xiao Mu flatly refused.

Others might fear this brute, but he did not.

"Friend, don't be so quick to decline. Maybe you will like what I have to offer."

The brute's tone exuded strong confidence as if he had no fear Xiao Mu would refuse his offer.

"Oh!"

Xiao Mu grew curious, "What are you prepared to trade?"

"Have a look first."

Saying this, the brute suddenly tossed a tightly sealed small glass bottle to Xiao Mu.

Beyond its exceptional seal, it was an ordinary glass bottle. But faint hints of Spiritual Energy hinted that it contained something valuable.

What is it?

Spotting the energy emanating from the bottle, Xiao Mu's expression shifted slightly, intuiting a hint of what it might be.

He took the glass bottle in his hand and looked at the brute, "What's inside?"

The brute motioned towards Xiao Mu, implying for him to open it and see, "Open it. Then you'll know."

Xiao Mu twisted the bottle's cap off, and a rich scent of medicine wafted out.

Elixir!

Xiao Mu made a mental note.

He poured out the bottle's contents onto the lid, revealing a dark green pill about the size of a thumb.

The pill emanated a muffled light, oozing with irreversible spirituality. The scent permeated the area within a few meters with a strange fragrance.

"That's the Qingyang Pill! That is the Qingyang Pill!"

Among the onlookers, a mutant yelled out loud, immediately recognizing the name of the pill. Based on his tone of surprise, it seemed that this Qingyang Pill was no simple matter.

"Qingyang Pill? This is the Qingyang Pill?"

Another older mutant recognized the name of the Qingyang Pill, his face revealing a shocked expression. He muttered to himself in disbelief, "There really is such an elixir? Incredible, simply incredible!"

A young woman, about twenty, was staring fixedly at the Qingyang Pill in Xiao Mu's hand, her eyes almost unmoving, "I didn't think the Qingyang Pill was real. I always thought it was a myth. It would be great if I could get one."

"Qingyang Pill, it's said to originate from a certain secretive pharmaceutical family clan. This is due to a mutation that occurred in an ancient recipe owned by their family, turning it into a true elixir scripture. Based on this scripture, they refined the Qingyang Pill."

"It is said that this Qingyang Pill can be used as an energy fruit, and its efficacy is even stronger than that of an energy fruit."

"The boss is really lucky. If it were me, I would definitely exchange."

The spectators murmured among themselves, all discussing the Qingyang Pill. They felt that the exchange of the Flying Sword Fragment for the Qingyang Pill was a lucrative deal for Xiao Mu.

"How about it? My friend, would you use a Qingyang Pill to exchange for your Flying Sword Fragment as a substitute for an energy fruit?"

The muscular man had a smug look on his face, a face that was not afraid that Xiao Mu would reject him.

Xiao Mu paid no heed to the spectators' chatter.

In fact, Xiao Mu had heard of such a type of pill like the Qingyang Pill and knew that certain ancient alchemic books could indeed mutate into a true alchemy manual.

Such an alchemy manual could indeed be used to refine various kinds of medicinal pills.

If Xiao Mu were not short of resources and time, he himself would have even considered making his own elixirs.

However, one objective condition led him to abandon the idea.

The scriptures mutated from alchemy books are real. Still, the required pill ingredients are extremely difficult to find.

These special medicinal pills cannot be refined simply by gathering ordinary medicinal materials in the human world. In fact, most of the medicinal materials are mutated ones.

Each of these mutated medicinal materials is not easy to find. Gathering them altogether is even more challenging.

Xiao Mu, therefore, gave up on refining pills for this exact reason.

Even for him, these mutated medicinal materials were not easy to find.

He has the Mutation Technique that could mutate ordinary medicinal plants.

However, the problem was that many medicinal plants had unknown constituents that made a successful mutation uncertain.

Gazing at the Qingyang Pill in front of him, Xiao Mu shook his head slightly. He couldn't believe that someone could gather richer resources than him to accumulate the ingredients required to refine actual medicinal pills.

Picking up the Qingyang Pill and sniffing it, the rich fragrance of the pill was accompanied by a rather pungent smell that was barely noticeable.

If it hadn't been for Xiao Mu's keen spiritual perception, he might not have noticed at all.

"Hehe!"

He chuckled, put the Qingyang Pill back into the glass bottle, tightened the lid, and casually threw it back to the muscular man.

"What? My friend, you don't appreciate my Qingyang Pill?"

The muscular man's brow furrowed, and a thick displeasure surfaced on his face.

Without batting an eye, Xiao Mu casually asked, "How did you guys remove the toxicity after substituting ordinary medicinal materials for the mutated main ingredient?"

The muscular man was taken aback, looking at Xiao Mu in extreme surprise.

He couldn't figure out how Xiao Mu managed to spot the problem with the Qingyang Pill.

"What? There's toxicity?"

"They replaced the mutated main ingredient with ordinary medicinal ingredients?"

"So the Qingyang Pill is actually a counterfeit?"

"No wonder there's a pill that's even more amazing than an energy fruit. It turns out to be a counterfeit that replaced the main ingredient."

The onlookers gasped and started discussing loudly, finding it hard to believe.

"My friend, it's okay if you are not willing to exchange, but accusing my Qingyang Pill of having problems is crossing the line!"

Listening to the onlookers' comments, the muscular man's face turned dark, and there was a killing intent in his eyes towards Xiao Mu.

"What? You want to try something against me?"

Xiao Mu sneered while emitting a powerful energy.

It was one thing for the muscular man to bully others, but he definitely picked the wrong person to trifle with when he decided to intimidate Xiao Mu.

This unmasked energy surged towards the muscular man like a forceful tidal wave, making the air ripple like the surface of water.

An invisible force pressed against the muscular man as if he was under a mountain, and he knelt down on the spot.

"You~"

The muscular man's face turned pale, struggling against the energy Xiao Mu was releasing. Xiao Mu's power was overwhelming, making him feel like he was being crushed.

Even though it was only the force being exerted, he was completely unable to resist it.

The gap between the Third Realm and the Fourth Realm was unimaginably vast.
