I am a mage, with an infinite mana bar!

Faced with the threat of death, he became agitated and spoke with absolute certainty, not at all like someone who was lying.

So, the original owner didn't die because of that potion?

Lynn hesitated for a moment, then said sternly, "You're a spellcaster too, aren't you? Swear to me that what you just said is true."

The bat's face was somewhat distorted, but seeing that things were turning around, it could only snort coldly and struggle to raise its right claw.

"By magic above, by the Brown Star which governs the fate of all living beings, I, Carlisle Reid, swear that what I have just said is the truth."

Lynn nodded in satisfaction.

The world's oath to the "Brown Star" is really useful.

"Let me go! Why should I let a man like you hold me like this!"

As soon as Lynn let go, he slipped behind the partition in the hotel room's changing room.

Gray smoke billowed, and then a young man with black hair and red eyes emerged from behind the partition, dressed in a suit.

He was indeed handsome, with pale skin and deep features, yet he also possessed a somewhat effeminate air.

The vampires in this world don't seem to be considered an evil race. Because they need to drink fresh blood frequently, they like to live among humanoid races and obtain food through trade... Lynn recalled quickly.

Carlisle gritted his teeth and glared fiercely at Lynn, seemingly still reeling from the anger of being misunderstood and coerced.

But when his gaze fell upon the Frost Ring beside Lynn, which was in a semi-standby state and radiated a dangerous aura of cold light, he immediately shivered and looked away while adjusting his collar.

"Where's the medicine?"

When he saw Lynn extend his hand to him, Carlisle frowned, a hint of doubt in his red eyes.

"Didn't I already pay a deposit? Otherwise, you wouldn't have come all the way to knock on my window in the middle of the night. I must say, you're quite trustworthy."

Although there were gaps in her memory, Lynn could easily guess, based on Carlisle's account and the note tucked in the book, that the original owner must have secretly contacted Carlisle's "informant" to buy more drugs while "high on the drugs" and had paid a deposit in advance.

However, you obviously won't get any discounts when buying medicine a second time.

Carlisle proudly raised his chin. "Of course! I'm the most trustworthy potion merchant in all of Roan!"

As he spoke, he reached for his waist, then looked at Lynn with a strange expression and said, "Didn't you just say your friend died after drinking my potion? You really are a liar. You're not trying to take advantage of me to lower the price, are you...?"

He spoke the second half of his sentence very softly, but it didn't stop Lynn from hearing it clearly.

The Frost Ring was instantly placed against his neck.

"Stop dawdling and get the medicine out now."

Carlisle's already pale face turned even paler, and she shakily handed him the medicine bottle.

But he kept muttering to himself, "You, you're acting like one of those drug addicts who're high on Raman's Herb! Strange, my potions don't make people addicted..."

Lynn took the so-called "angel and devil coexistence" potion and examined it closely.

This is a bottle of potion that looks very strange. Through the glass bottle, various colors condense into a murky mass, and it keeps changing.

It's hard for you to describe exactly what colors you saw.

Lynn wanted to open the bottle to smell the aroma, but Carlisle immediately stopped him.

"Don't open it carelessly. Once opened, drink it within a short time, or the potion will lose its effect!"

Lynn remained expressionless and asked directly, "What ingredients did you use to make this medicine?"

His performance was extremely imposing due to the imminent threat of the Frost Ring.

Carlisle was clearly angry, but he suppressed his rage and patiently explained, "This is a trade secret. How could I possibly tell you? Besides, I've sworn never to say it..."

He glanced at the potion in Lynn's hand and continued, "I can assure you that all the materials I use are legitimate, safe, and in accordance with the standards of the Potion Making Code!"

"Originally, its effects would have been even more unpredictable, but thanks to the meticulous optimization by the genius pharmacist Carlisle," he raised his chin and patted his chest, "its negative effects have been kept within an acceptable range, but correspondingly, the positive effects have also been weakened considerably."

Lynn recalled what he had just said: "A one-in-half chance, success means making a fortune!"

What are the positive effects?

Seeing that the conversation had finally gotten back on track, Carlisle felt much more relaxed and began to introduce the topic with great interest:

"There are many possibilities. For example, for a period of time, you will gain a unique charm that makes you invincible in your interactions with the opposite sex. It's worth mentioning that the opposite negative effect is that you will gain strong attraction to the same sex..."

"For example, you might temporarily gain a magical ability that can help you solve your current difficulties. Even better, if you're lucky enough, drinking this potion could permanently enhance a specific ability you desperately need!"

A permanent upgrade?! The positive effects of this potion are incredibly powerful? However, the difference between its upper and lower limits seems quite large…

Lynn was surprised, but outwardly he just looked at Carlisle calmly. He realized that as long as he didn't interrupt, the guy could keep talking.

"Moreover, after the improvements made by the genius pharmacist, that is, me, the 'Potion of Destiny' has undergone a revolutionary innovation—"

"If you drink it and experience a negative effect, then the next potion of fate you drink within a month will definitely have a positive effect!"

He seemed to have forgotten the Frost Ring so close at hand, and became extremely smug, saying to Lynn, "Therefore, the price will double if you buy it within a month! Such a good potion, I can only make a maximum of three bottles a month! And that's only if I'm extremely lucky! Charging you 3 gold coins isn't unreasonable, is it?"

"3 gold coins?" Lynn almost lost control of his expression. His entire fortune was only a little over 2 gold coins!

Carlisle held out his hand to him, saying with an expression that said, "Selling it to you at this price is practically giving it away for free. You've paid a deposit of 1 gold coin, so you have 2 gold coins left."

"..."

Lynn silently put away the potion, and then gently brushed Carlisle's hand away under his shocked gaze.

"My name is Lynn Lowell. You claim to be a noble vampire, yet you don't even understand basic social etiquette?"

Carlisle's face stiffened upon hearing this. Vampires have always been proud of their bloodline and identity, and he did not expect Lynn to target this point.

Before the other party could react, Lynn continued his pursuit, his tone icy:

"The friend I mentioned before met with misfortune after drinking your potion and going insane."

"So, it's an undeniable fact that you indirectly caused my friend's death, Mr. Carlisle. What would happen if I reported this, along with your illegal sale of counterfeit medicine, to the authorities? Mr. Barton of the Magic Association is extremely intolerant of any wrongdoing."

Carlisle's face turned extremely ugly, especially after hearing Barton's name, as if he had suddenly thought of something bad.

"What I'm selling isn't fake medicine. I've explained it to you so many times, you should understand by now. It's the 'Potion of Destiny,' a miraculous medicine!"

Lynn's expression softened, and his tone was slightly regretful. "Mr. Carlisle, of course I'd like to believe you, but unfortunately I don't have the chance."

"How about we use this potion you brought today as evidence? If what you say is true, not only will our misunderstanding be cleared up, but I will also help you win over other customers."

"For example, Miss Eli, daughter of the Lord of Roan City and the Frey family."
