The fairy maid cheers for her deceased master today.

Having achieved his goal, Axelsen naturally had no reason to stay at the club.

Axe quickly found Manager Smith, nodded slightly to him, and with a perfectly polite smile on his face, said:

"Thank you for your cooperation, Manager Smith. Initial inspection shows that the club's security measures are adequate and there is absolutely no sign of any alien presence. We will submit a detailed report to the Holy See."

Angel stood obediently beside X, as always.

"That's great, Sir." Manager Smith breathed a sigh of relief and straightened his bow tie. "Please let us know if there's anything else we can do to assist you with."

"Of course." Ex nodded gently.

"However..." Manager Smith subconsciously raised his hand.

"Is there anything else?"

"It's not that I don't trust you, Sir. It's just that, are you really 100% sure there are no outsiders in the club?"

"Rest assured, I guarantee it with Angel's life."

"That's good." Manager Smith nodded again.

"That's right, don't worry...wait?" Angel suddenly felt something was wrong.

Then X almost burst out laughing, and said, "I was just kidding, Angel. Let's go."

"Don't make jokes like that anymore!... Hmm, Master, let's go!"

Holding Angel's little hand, X walked towards the door.

The club's heavy, ornate doors slowly closed behind them, the brass door knockers making a dull thud, temporarily shutting out the secret world filled with cigar smoke and the passion of combat.

■

Angel originally thought that her master would go straight back to the Miracle Workshop.

Since the owner didn't say where they were going, the default assumption was that they were going home.

To everyone's surprise, Ax immediately flagged down a carriage, heading to the London Patent Office.

Angel asked curiously, "Master, where are we going...?"

But X simply took out the cobalt blue glass bottle, turned it over, and looked again at the "M-07" number engraved on the bottom.

Ex fiddled with the glass bottle for a while before saying, "I already know what this is."

"Why!!!"

"Of course, I knew it through magic."

Ex smiled at Angel.

The formula for this potion is clearly visible on X's panel.

[Drek Vitality Essence (made in 1851) + Silver Foil Powder (refined by London goldsmiths) + Sulfur Ore Powder (ground in Somerset) + Echinacea Extract (extracted in Norfolk) = 1 bottle of Fairy Healing Essence]

This formula shows an equivalent exchange formula using the potion in hand as the material...

Therefore, the substance in this blue glass bottle is called "Derrey Vitality Element".

This must be the product name. But I've never heard of this medicine on the market before.

So, wanting to find information about it... X immediately thought of the Patent Office.

If the nobles behind the drug want to make money from it, they will definitely apply for a patent in advance.

Soon, at the patent office, an elderly administrator wearing gold-rimmed glasses greeted them with a smile. The cuffs of his tuxedo were slightly frayed, but he was still neat and tidy.

"Which area of ​​patent records would you like to consult?"

"Focus on the drug patents from recent years, no, the last two years, and look for relevant documents for 'Derui Vitality Supplement'," Axe replied politely.

After collecting a small handling fee, the administrator respectfully led them through rows of tall bookshelves to an oak compartment marked "Pharmaceutical Patent of 1850-1851".

He skillfully climbed the ladder and took down a leather-bound booklet, the gold lettering on the cover already somewhat faded: "These are the two, Sir."

Ax thanked the administrator, found a table nearby, and spread the booklet on the dark green felt tabletop.

He then carefully turned the yellowed pages.

After flipping through it for quite a while...

「……GB1850/0472号专利，德瑞活力素，主要成分：对氨基苯酚衍生物（60%）、哥伦比亚咖啡因提取物（25%）、微量印度马钱子硷（15%）……原来如此。」

Ax tapped the tabletop lightly with his fingertips, making a rhythmic sound.

Angel curiously leaned closer, her little head almost touching the medicine bottle on the table, her nose nearly brushing against the cool glass: "Master, have you discovered some secret?"

Axe casually ruffled her soft silver hair: "The applicant for this drug is: Mueller Pharmaceuticals."

In other words—

This medicine, provided by Caroline, is a patented product of Mueller Pharmaceuticals.

It's almost certain that Caroline has another identity: she's a fairy from the Mueller Pharmaceuticals company.

Ax smiled and continued to explain the formula: "It says here that its core ingredient is a para-aminophenol derivative—the main ingredient in our commonly used antipyretics—combined with caffeine extract for a stimulant effect, and then a trace amount of strychnine for a brief stimulation of the nervous system."

Angel subconsciously bit her nails: "A demonic spirit?"

"Although strychnine is highly poisonous, it can precisely activate the magical circuits within a fairy's body in extremely small doses. This is the little secret behind its ability to enhance a fairy's power... That's what it says here."

Angel nodded as if she understood, her little hand gently stroking the texture of the medicine bottle.

"That……"

"Moreover, Caroline is not an ordinary company employee."

Seeing that Angel still didn't understand, X pointed to the Gothic script on the page.

Angel also came over to take a look and found that the signature at the end of the patent read: Caroline.

It seems Caroline is not only a researcher, but also a core developer of this patent. Her role at Mueller Pharmaceuticals is certainly not simple.

It seems that the noble background behind Caroline is about to be revealed.

So he put down the patent booklet and started chatting casually with the administrator next to him.

"Moeller Pharmaceuticals is really amazing; so many patents are related to them."

"Haha, that's true."

"Which nobleman owns it? It seems like a very sophisticated company," Ax inquired directly.

The old administrator thought for a moment and said, "This is actually quite easy to investigate. Mueller Pharmaceuticals is a very famous company, and its owner... is a baron named Simon. This baron is quite well-known and has made many contributions to the city of London."

Is Baron Simon behind Caroline?

Since Officer James and Caroline are in cahoots, James is also loyal to Sir Simon.

Wait, let me sort this out first.

James once said that he actually hoped his team of detectives would continue investigating the whereabouts of the magical silverware.

In other words, Caroline and James also didn't know where the magic silverware went; they suspected that the fairy Lucy knew the inside story about the magic silverware.

Therefore, Caroline tried to force Lucy to reveal the truth, but Lucy ended up killing her instead.

But why did James warn Lucy at this point, saying not to look for her anymore?

If James's goal is still to find the whereabouts of the silverware, then does he... know that looking for Lucy is pointless?

In other words...

James believes, or James knows, that the fairy Lucy is also dead.

This is a more reasonable explanation.

No, there's another possibility. It's that James simply doesn't want to find Lucy himself... His pursuit of the fairy Lucy might be because Lucy has other secrets she doesn't want outsiders to know.

This is a headache; there are still too few clues.

Thinking this, Axe casually continued, "What great contributions did that Baron Simon make?"

"Haha, that's quite a lot. They're very famous in London."

The administrator responded with a smile.

"Baron Simon has made great contributions to the fight against cults in London."
