Before Mrs. Hudson could finish speaking, Leonardo stood up angrily, staring at Mrs. Hudson with his eyes full of loss and resentment, and then looked at Eric again, and suddenly fell to the couch as if he had lost his center of gravity, his eyes suddenly glazed over. Mrs. Hudson sighed softly and looked at the talented scientist with pity.

"And what is this book about?" Chiko couldn't help but want to peek into this ancient secret.

At this point, Mrs. Hudson smiled mysteriously, and she asked Eric, "How's it going, detective, there are rumors in the political circles that President Jefferson's think tank has a detective who calls himself a disciple of Sherlock Holmes." Now, then, the Holmes disciples, are they interested in unlocking the secrets that this Nicholas disciple has kept?

"I can give you one more hint, turning stones into gold. At this time, Chiko noticed that there seemed to be an unfathomable whirlpool in Mrs. Hudson's eyes.

Eric pursed his lips and folded his hands against his chin, he had to accept the challenge. So what is turning stones into gold, and what is the hidden meaning of turning stones into gold? Nicholas deduced redstone with mercury, mercury to redstone—stone to gold, and Eric faintly heard the footsteps of the truth

"Whether it's turning stones into gold, or Nicholas's account of mercury deducing redstones, both of them are converting the same class of matter, and I think the secret of this book should be related to the transformation of matter. After an intense self-brainstorming session, Eric opened his eyes and spoke the voice of truth.

Hearing Eric's answer, Leonardo let out his characteristic snort unconvinced, while Mrs. Hudson nodded approvingly and continued to ask, "Anything else?"

Eric continues: "The reason why we were fortunate enough to meet the Nicholas School was the search for the Smiling Legion, and it was the study of neurological extension and mirror reflex that led Leonardo to Paris. According to this old thing, this research has a lot to do with Dora's reagent. But the core of its theory is to replace the mirror stimuli generated near the nerve center. So, I think the secret has something to do with nerve cells, or even the transition between cells. ”

Mrs. Hudson was silent for a moment, then said approvingly, "As a layman, you can reason to this point enough to prove that Jefferson was not wrong. Hearing Mrs. Hudson's voice, Eric still didn't seem to have guessed all the answers, which really frustrated Eric a little.

Mrs. Hudson picked up a remote control board and pressed a red button. Suddenly, a black four-way projector descended from the roof of the chamber. Only a "click" was heard, and the projector projected four white lights in four directions, and in the blink of an eye, four holograms appeared in four directions. The images are all men and women in black robes, with different expressions and behaviors, but they are all lifelike.

Mrs. Hudson smiled mysteriously again: "I think some of these must be known to you. Sure enough, as he said, there are many famous historical figures in these images, and these extraordinary historical figures all have a common identity - scientists.

Could it be that these people are all related to the Nicholas School? Chiko sighed in her heart.

Eric seemed to see the doorway, and he was surprised and said, "The secret of this transformation is not just the transformation between matter and cell?"

Mrs. Hudson walked up to Newton and Leibniz's images and explained: "Yes, before Newton, we thought that the secret of Nicholas was the transformation between the elements. With the discovery of the three laws of gravity on the earth and the derivation of mathematical theorems from the mechanical formulas, the sages of the school discovered that the transformation of the world seems to transcend any attribute or category. Leonardo, on the other hand, discovered the secret of the transformation of nerve cells hidden in it, and was the first member of the school to discover the secret of transformation in biological nerves."

Hearing Mrs. Hudson's introduction, Chiko and Caitlin couldn't help but look at Leonardo, thinking that he was just a lonely genius scientist, but they didn't expect him to be able to stand shoulder to shoulder with these scientific giants.

"But according to you, Nicholas's secrets are in this parchment, so why is this silver suitcase what the Nicholas School really guards? Caitlyn raises a key contradiction.

"Because inside this silver box is the key to open the secret. Before Mrs. Hudson could speak, Eric gave the answer, "As we have just seen, this Jewish Book of Abraham is copied from Nicholas's alchemical code, so to really understand the contents of the book, you must parse these codes, and I think this suitcase should contain the code book that parses these symbols and words on the book." ”

"There's nothing wrong with that. Mrs. Hudson smiled mysteriously, "Do you want to know what the magic of this book is?" Under Mrs. Hudson's seduction, Chiko and Caitlin became even more eager for this secret that had made the great scientific legend several times, and they invariably stared at the silver suitcase full of magic.

At this point, Leonardo protested resolutely, "It's not in order, Mrs. Hudson, I think you need to know who these people are, two damn agents, plus an unobtrusive curly-haired detective who pretended not to have been to this tunnel two years ago." I even suspect that the gang that is still circling in the tunnels has something to do with him!

Eric then retorted, "Damn, use your butter-stuffed brain, if I had been through this tunnel and was with the gang that ambushed you, I should have fled with my suitcase in my arms." ”

Not to be outdone, Leonardo said: "Who knows what other intentions you have, maybe you want to follow here and make some extra money, oh, by the way, Mrs. Hudson is the Speaker of the House of Lords, and she is a good target for blackmail." Or you still want to get this "Jewish Book of Abraham", the goose has been plucked, and there is no hair left, which is very suitable for your character. ”

Seeing that the "fire" between Eric and Leonardo was about to ignite, Mrs. Hudson walked behind Leonardo from Newton's image, patted him gently on the shoulder with one hand, and made a calm gesture towards Eric with the other. Sure enough, the scolding battle between Eric and Leonardo came to an abrupt end and turned into a fight between the eyes, which made Chiko and Caitlin, who were also women, admire.

"All the answers are in this box. Open it, Eric, and I'm empowering you as head of the Nicholas School. Mrs. Hudson's mouth showed an indescribable solemnity.

Hearing that Mrs. Hudson asked Eric to open the box by himself, Leonardo was slightly stunned, this box can only be opened by a very small number of people in the Nicholas School, and Mrs. Hudson should know this very well. Although Eric had seen the suitcase 2 years ago, he didn't have the permission to open it, and he didn't even know how to open it.

Eric looked at the slightly old suitcase in front of him, and suddenly, when his fingers brushed the mottled scratches on the box, Erik's heart turned over with a strange sound:

"Open it!"
