"Well, after all, there are some subtle places that are not clearly described, so it's better for you to investigate privately!"

Seeing Holmes get up, Firena, after thinking about it for a while, also felt that instead of letting him follow her, it was better to let him go out to investigate the situation outside, after all, he was not a detective, and he could not pay attention to the things around him like them.

"In that case, then without further ado, I'll go first!"

Gracefully saluting Ferena, Holmes then turned, and in a burst of white light, his form gradually changed, and when the light completely dissipated, Holmes was transformed into an old English gentleman with a white beard but a strong spirit.

Circling Sherlock Holmes twice, Firena couldn't help but be amazed as she took a closer look at his appearance.

"Ho, it's worthy of a disguised treasure [Empty House], if I didn't know your true identity, I'm afraid I would really think of you as a stranger, and without consciously perceiving it, your magic seems to have been covered up to a certain extent!"

It's not the first time I've seen a cross-dressing treasure, as the strongest of the Knights of the Round Table, Firena has also seen Lancelot's cross-dressing treasure - not for her own glory, although both of them have a B-level cross-dressing treasure, but compared to Lancelot, the treasure used by Sherlock Holmes seems to be more able to hide his own magic fluctuations.

"Haha, thank you for the compliment, it's really my honor."

Lifting his gentleman's hat slightly, Holmes then turned the gentleman's crutch in his hand and walked gracefully towards the door.

"So say goodbye for now, master!"

"Well, I wish you can find the clues you want, but you have to remember that if you have any major clues, you must report them to me as soon as possible."

Afraid that Holmes would keep the secret in her heart until the mystery was revealed, Firena specially told him before she was about to go out, and she didn't know whether she listened to it or not.

"Of course there is no problem, after all, from the chat just now, it seems that Miss Firena, you can be a very effective assistant!"

With a slight elegant smile, Holmes said a word, and then disappeared in front of the two of Firena.

"Senior, Mr. Holmes is gone!" As a big fan of the Sherlock Holmes detective series, Matthew was a little reluctant to get his so-called gift after Holmes left.

However, through the communication between her master and Sherlock Holmes just now, Matthew also understood that the current situation was not optimistic, although it was not to the level of 100,000 urgency, but it was also difficult, so she asked without thinking too much.

"Senior, where do we need to go next? Please give us your instructions. ”

"Hahaha, take it easy, Matthew! We are now on the advantageous side. ”

Firena couldn't help but laugh at the serious appearance of her schoolgirl, then took her hand and walked towards Mata Harry's hut.

"Let's go, let's go to Paracelsus now and see if he needs our help."

Comforted by the way, Matthew recovered from his nervous tension, and when Firena and the others arrived at Mata Harry's house, they found that a cabin had been built next to the small building where the dancer lived, and Paracelsus was playing something in the cabin.

Although his left arm was severed by the Emiya, this did not affect Paracelsus's work in the slightest, and thanks to the work of the elemental robots he created, the cabin has now been turned into a full-fledged laboratory, and the plan to make the Philosopher's Stone is also well underway.

Seeing Firena's arrival, Paracelsus came out to greet them warmly, and after greeting them for a while, after learning of their intentions, he arranged for the two of them to do the simplest and easiest job, and then went about his own business without touching the ground.

The making of the Philosopher's Stone was extremely cumbersome, and although Paracelsus gave the two of them the simplest work, the refining of raw materials alone was already a headache for Firena, who had studied alchemy, and the whole refining process was extremely boring, and it would be frustrating to do for a long time.

Although Firena didn't plan to give up once, she came to the door by herself at the beginning, and now she can only knock out her teeth and swallow it in her stomach.

……

"Senpai, is it right here?"

"Matthew, yes, yes, that's the place, push harder! Uh-huh~! ”

Lying on the bed, Firena gestured to Matthew behind her, and her mouth could not help but hum comfortably as a moderate pressure came from her stiff shoulder.

The bright moonlight poured through the window into the room of Firena, who had been busy at Paracelsus until about twelve o'clock in the evening, but after a day of mechanical work, Firena was physically and mentally exhausted.

"Senior, judging from the progress reported by Paracelsus just now, the Philosopher's Stone may be able to be made the day after tomorrow!" With a smile on the corner of his mouth, looking at the chirp leaking from the corner of the little master's mouth in front of him, Matthew's eyes revealed a touch of pampering.

As a servant, Matthew loves her alone time with her master, and for some reason, as long as she stays by Firena's side, she feels a warm sense of security in her heart.

"Hmph, don't worry, since Paracelsus is sure that it will be completed in two days, then he will not easily break his promise, huh~! Let's just wait here for news from him. ”

"I wonder what happened to Mr. Holmes? If we can find the location of the evil people at this time, we will be able to gather the power of all the servants and defeat them in one fell swoop, and then we will be able to leave this world. ”

"Unless you don't do it, nothing in this world is seamless, Holmes as a 'revealer' in the world, you will definitely be able to find the evil at this time, as his senior fan, you have to have faith in him."

Enjoying Matthew's massage, Firena can be said to be very relieved of Sherlock Holmes, as a treasure that is always activated, as long as there is Lao Fu, there is no clue that cannot be found.

"Of course I know this, senior, I just want to leave this world sooner!"

"Instead of thinking about leaving this world, it's better to lie in bed and go to bed early, and only then can you have the strength to have a duel with the Wei Gong and them."

Pulling Mathieu closer to the bed, Firena then put her arms around the other's waist and fell asleep, but in the night, a pair of devil's claws were quietly reaching for them.
