Lynn stared wide-eyed.

Without another word.

He quickly opened the counter and pulled out the high-quality enhancement potion his teacher had meticulously researched from the cabinet's mouth.

"Please try this one, I guarantee you'll be satisfied this time."

Lynn said seriously.

[Top-grade Frenzy Potion]: Can greatly enhance all-around abilities and cause the target to enter a frenzied state.

He placed the blood-red potion bottle on the table.

Without a doubt.

This potion was absolutely the top-quality medicine their Bloodsaw Potion Shop kept in reserve!

The Black Knight reached out, grabbed the potion bottle, and drank it all in one gulp.

Instantly.

A red glow flashed across his body, and faint traces of blood-red appeared in his eyes—clearly the potion taking effect.

[Ding! Crisis Level 20%]

"Minimal effect."

The Black Knight casually tossed away the empty bottle, saying hoarsely:

"This kind of potion might work on weaker creatures, but for me, it's basically negligible."

"......"

Lynn stared wide-eyed, quickly pulling out another high-quality potion from under the counter, saying:

"Then please try this one!"

"Trash quality!"

[Crisis Level 30%]

...

"How about this?!"

"For treating hemorrhoids."

[Crisis Level 40%]

...

"This one is absolutely the best!"

"Expired!"

[Crisis Level 60%]

"......"

Several minutes later, Lynn looked gravely at the collection of empty bottles on the counter, then at the clearly impatient Black Knight.

Obviously, for a Black Knight of this level, the potions their shop sold simply couldn't meet his requirements.

[Crisis Level 91%]

Lynn's heart grew somewhat anxious.

This seemingly simple task.

Actually carried no less danger than those he'd done before.

"It seems your shop can't provide any better potions."

The Black Knight raised his head, cracking his neck with a clicking sound, saying hoarsely:

"You're wasting my time."

[Ding! Crisis Level 95%]

"Wait a moment!"

Seeing the crisis level about to max out, Lynn reached out, adjusted his monocle, and said calmly:

"Our shop has one more potion that I believe will absolutely meet your requirements, but I don't have it in stock—I need to brew it on the spot! You can wait for me for a while, I guarantee it's the best potion!"

The Black Knight said hoarsely: "Oh?"

Lynn said calmly: "If this potion still doesn't satisfy you, you can chop me down right then and there!"

[Ding! Crisis Level reduced by 5%]

The Black Knight's glowing eyes showed a flicker of interest as he said lightly:

"Is that so? Fine, I'll give you half an hour to brew it. As you said, if it doesn't satisfy me, I'll chop you down."

"Deal!" Lynn said seriously.

...

Lynn quickly rushed to the backyard. ɴᴇᴡ ɴᴏᴠᴇʟ ᴄʜᴀᴘᴛᴇʀs ᴀʀᴇ ᴘᴜʙʟɪsʜᴇᴅ ᴏɴ novelFɪre.net

Without another word.

He directly pulled out the recipe rewarded by the system when he healed that Origin-Level Monster from his system space.

[Critical Hit Potion]

[Quality]: Special

[Materials]: Origin-Level Biological Tissue x1, Explosive Fruit Pulp x1, Hell Clover x4, Black Bat Wing x1, etc.

[Description]: A potion that can greatly increase critical hit rate, but comes with some negligible strange side effects...

The reward for healing the Origin Monster.

This was absolutely the best potion he could offer.

"Nothing ventured, nothing gained. The potion recipe rewarded by the system should definitely be better than other potions in this world!"

Lynn's expression was serious.

He quickly rushed into the warehouse, gathering various brewing materials needed for the potion.

Most of the materials had corresponding stock in his teacher's warehouse.

And the most difficult to obtain Origin-Level biological tissue—he had that too.

Last night when fixing that Headhunter's teeth, he had collected plenty of tooth fragments and that monster's oral mucus.

He had kept it all.

Absolutely premium material.

After preparing the materials, Lynn quickly rushed to the alchemy lab in the backyard.

Ready to start brewing!

His alchemy level wasn't very high, but two years of learning from his teacher had greatly improved his skills.

"Start brewing!"

[Ding! You ground medicinal powder, alchemy experience +1]

[Ding! You extracted explosive fruit pulp, alchemy experience +1]

[Ding! You purified slime mucus, alchemy experience +1]

Bubble bubble—

In front of the large vat, Lynn stirred the thick, viscous mucus continuously emitting strange bubbles with a stick.

The fire burned fiercely.

Lynn wore a mask, his expression serious.

"First add black bat wings, then mandible wolf spider fangs."

[Ding! You added potion materials, alchemy experience +1]

Boom—

The large vat of potion instantly turned from white to purple, bubbling up with one skull-shaped bubble after another.

Lynn stood indifferently before the large vat, stirring continuously.

The potion in the vat kept transforming through various colors—red, blue, black, purple, and more.

Time flew by quickly.

Soon.

Twenty minutes passed in the blink of an eye.

[Ding! You brewed Critical Hit Potion x1, alchemy experience +10]

Accompanied by system notifications.

Lynn quickly poured the potion into empty bottles, placing them rapidly on the table counter with a series of taps.

A full ten Critical Hit Potions!

Instantly giving him an additional 100 points of alchemy experience.

[Critical Hit Potion]: For humanoid creatures only, can increase target's critical hit rate by 100%, but comes with some small side effects...

"Whether we can pass this hurdle depends on this potion's effectiveness!"

Lynn's expression was serious.

...

Main hall.

Lynn seriously pushed the black-red Critical Hit Potion toward the Black Knight.

He adjusted his monocle, saying solemnly:

"Critical Hit Potion, our shop's newly launched high-quality potion. You're the first customer for this potion—its effectiveness will be determined by your judgment!"

The Black Knight glanced at the plain-looking potion bottle.

He played with it in his hand, saying lightly:

"Are you sure this is the best potion you have here? Think carefully—if this potion still doesn't meet my required standards, I'll honor our earlier agreement and chop you down."

Lynn said calmly: "I absolutely guarantee your satisfaction!"

But truthfully, Lynn's heart was drumming with uncertainty.

After all, he didn't have a precise understanding of how effective this potion really was.

But at this point.

He really could only trust the system's quality!

Click—

The Black Knight opened the wooden stopper on the potion bottle.

Instantly, a faint pungent odor wafted out, and the moment he smelled this scent, the Black Knight suddenly froze.

Foul stench! Clearly the smell was absolutely unpleasant.

But surprisingly, just smelling this medicinal aroma made him feel a significant reaction in the power surging through his body.

For someone who had been taking potions for years.

This was a sensation he hadn't experienced in a long time.

He became serious.

Picking up the potion bottle, he opened his mouth and drank it all in one gulp.

Hum—

Almost instantly, he immediately felt an intensely bitter heat surge roaring through his body.

"This... this power!"

He trembled as he looked at his own arms, suddenly standing up.
