"What is this place?" Chiko repeated her doubts.

Eric stared solemnly at the giant alchemical symbol, not saying a word. At this time, Leonardo*, who had passed out all the way, woke up. When he opened his eyes and saw the environment, Leonardo pursed his lips, savoring every inch of space with a nostalgic look.

"This is supposed to be the holy place of the Nicholas School. Eric finally spoke.

"What?" Catelyn was taken aback by hearing Eric's answer.

"The Nicholas School?Holy Land?" Chiko was still confused.

Eric walked over to the circular pool in the center, gently stroked the edge of the pool, and explained, "Remember Leonardo who took us to discover the alchemist's mark? In addition to this pool, I once saw a book on the Nicholas school in the private collection of a wealthy man, and there was an image of this pool. It was created by the disciples of Nicholas Flammel, Europe's most legendary alchemist, with the aim of preserving and protecting the secrets of Nicholas' alchemy. Now I understand, Leonardo, you should be one of the core figures of the Nicholas School, and one of the main guardians of the secrets that Nicholas has passed down from generation to generation. ”

Leonardo still didn't answer, but said lightly: "It's not unusual for you to know this, two years ago, today, if you can't guess it, you're not Eric." ”

Caitlyn asked, "Could it be that Mrs. Rose, who is also the Ruth in Leonardo's mouth, and the black-robed people she brought with her, are also members of the Nicholas School?"

Leonardo didn't answer, as if he was thinking about something, but his eyes already gave the answer. And Eric can better understand Leonardo's grief, after Leonardo was involved in a murder incident 2 years ago, although he not only helped Leonardo clear his suspicions, but also helped him escape from the surveillance of the Special Intelligence Department of Country E, but he did not expect to be chased and killed by the Smiling Face Army halfway. At that time, several black-robed men also appeared to protect them into the Notre-Dame Cathedral, and of course, in Leonardo's memory, they entered the underground tunnel of Bacchus. In that battle, agents of the External Security Bureau of Country F were also involved. Similar to today's situation, Leonardo's companions were not good at fighting, and suffered heavy casualties in the firefight.

Qianzi didn't expect that the struggle with the Smiling Face Army would become more and more complicated, initially thought that it would be a solo battle between the CIA and Felix of country M, but now it has been involved in the special intelligence department of country E, according to Eric's statement, perhaps the external security bureau of country F has been involved in this dispute as early as two years ago. Now, judging from the tunnel in which we are currently located, it seems that the Nicholas School, which stands behind Leonardo, also has considerable power.

Just as Qianzi was pondering, suddenly, Leonardo, who was still in deep thought, rushed towards Eric like crazy, knocked Eric to the ground, and pressed him to death. Leonardo roared with red eyes, "It must be you bastard detective." You are the only one who knows the secrets of this tunnel!I shouldn't have brought you here two years ago!" At this time, if it hadn't been for Chiko pulling Leonardo away in time, Eric would have been choked to the ground.

Eric rubbed his aching chest and retorted angrily, "I repeat, I met you in Notre Dame Cathedral for 2 years, not in this damn tunnel of the dead!"

"yes, did I hell 2 years ago! And if what happened 2 years ago was fake, then how did you get here?" Leonardo struggled desperately like a mad cow that had seen a red sight, "Damn, if you didn't want to get the secrets of the Nicholas School, you bastard detective with a head full of dollars would be kind enough to help me? Damn, I actually believed you again this time." ”

"The hell knows if your cranial nerves are short-circuited, you say I want to get the secrets of the Nicholas School? What secret? The Philosopher's Stone? Turning Stones into Gold? Immortal? Only you lunatics would believe this!" Eric shot back unceremoniously.

"In our holy places, it is rude to make such a dismissive look at the secrets we have guarded for generations. ”

A gentle voice lingered slowly through the tunnel. This voice is not Leonardo's, let alone Chiko and Caitlin's, it seems to have been born out of thin air like a ghost.

At this moment, the pool in the center of the tunnel suddenly vibrated slightly, and layers of ripples spread on the water surface from the inside out. A moment later, as if an invisible blade had split the water in the pool in half, a stone staircase appeared in the center of the pool leading to the bottom in the blink of an eye.

"Wow, wow, wow". The heels beat gracefully on the ancient stone staircase, and the mouth of the originally dark pool gradually revealed a hint of golden light. With the beat of the heels, the lights grew thicker and thicker, and except for Leonardo, the other three stared intently at the mouth of the pool in the center of the tunnel, while Chiko and Caitlyn had an extra dagger in their hands, which was originally a funerary object in the tunnel tomb.

Moments later, an old man who looked to be in his 60s appeared at the mouth of the pool. She carried an old kerosene lamp in her hand, and wore a black robe like Ruth's. She walked down to the mouth of the pool unhurriedly, took off the black hat covering her head, and unabashedly revealed her true face.

"You~you!" Caitlin was surprised to see the woman's true face, and was speechless for a moment. Since arriving in Lenkenshire, Chiko had never seen Catelyn so panicked, and couldn't help but be even more curious about the identity of this woman, who she was, and how could make Catelyn lose her temper to such an extent.

"Oh, if the Prime Minister of Country E knew that their Speaker of the House of Lords, Mrs. Hudson, had become an underground grave keeper in France, I wonder if he would be angry and launch a major impeachment?" said Eric, jokingly.

"What? She's the Speaker of the House of Lords of Country E," Chiko asked in surprise. Qianzi knows that the House of Lords of country E is also known as the House of Nobles, and the vast majority of members are descendants of the royal family, hereditary nobles and lifelong nobles of country E. Although it has been intermittently weakened by several prime ministers, it is still a political force to be reckoned with.

Caitlyn nodded, quickly regaining her composure. She added: "Not only that, but she is the most prestigious Speaker of the House of Lords in the history of Country E and the first Speaker of the House of Lords to run for the ouster of a Prime Minister. Caitlin still remembers the political turmoil of that year, when she had just joined the country E SI6, and at least half of the effectiveness of the SI6 was spent on the struggle between her and the prime minister.

Mrs. Hudson walked up to Leonardo, and she said calmly, "I have been out of office for a long time, and now I am just a scholar who likes to be quiet. ”

Leonardo angrily rebuked: "You shouldn't stay here, it's no longer safe here, Ruth and they ...... just now"

"I know. Mrs. Hudson gently interrupted Leonardo, "The Nicholas School has been hidden for hundreds of years, and now it's time for the final decision." ”

"But all of this could have been avoided, Mrs. Hudson! You know, we can do it!" Leonardo became very agitated again.
