The medieval glass-encased oil lamps glow faintly in the narrow corridor, and the medieval kerosene lamp-style sconces that stick to the walls extend to the depths of the corridor, like this corridor is endless, and the light shines through the glass cover on the yellow sandstone walls and sprinkles on the stone slabs full of cracks, reminding him that this is an ancient college with a history of more than 700 years.

However, Yan Funing looked at the corridor where only the two of them walked side by side, and did not feel the atmosphere of the academy at all, only felt eerie and terrifying, like the prison of the Inquisition in the Middle Ages.

Yan Funing, who was wearing a mask, calmly passed through several surveillances in the corridor, and did not find anyone intercepting him, so he was a little relieved, but Yan Funing knew that it was not that the security measures of the Wanling Academy were poor, but that the building above was not the focus in the first place, it was the place where the people of the Wanling Academy studied and conducted academic research normally, and the secrets that really belonged to the inner world were all in the underground I don't know how many meters deep.

He recalled the map Li Jiting gave him, and the place that led to the real Wanling Academy should be in the library, but Yan Funing knew that he was lucky to be able to use the carrier and the shielding ring to try his luck on the surface of the not a secret Wanling Academy, and if he wanted to try to see if he could enter the underground layer, it was purely to send him to death.

Yan Funing saw the moonlight in front of him from the spire hole, he quickened his pace slightly, walked to the hole door and looked out again, the wind blowing through the hall blew his black robe, and the cool north latitude night wind was mixed with grass and earth and smells, this is not far from the location of the Institute of Biology of Wanli College that Li Jiting circled for him.

Yan Funing quietly took a deep breath and continued to walk along the corridor inside, he didn't take a shortcut, he chose the inner circle of the academy that seemed to have more escape paths, and it seemed that there was no more surveillance, and he still walked in a relatively closed corridor, even if taking the inner circle would make him feel more secure, but he still chose the path that seemed to be more dangerous.

In fact, this is Yan Funing's first official mission, he has not really been sent to "work" in the years he was sent to Imperial College, and the external mission of Taijilong is still in Russia this summer, but it is more of an "internship", familiar with Taijilong's techniques and processes, and doing inconsequential things such as monitoring or something.

Before today, Yan Funing was mainly about upgrading, establishing contacts and researching academics, in fact, he was indeed classified in the Qianlong Group at the earliest, and was cultivated as the hidden pile of the Qianlong Group in the UK, so he was also in the Qianlong Group when he interned.

Originally, Yan Funing did not have the right to choose, but the reason why he had the right to choose later was because of his outstanding academic performance, which made the upper echelons of Taijilong feel that it was a bit of a waste if a talent like him was just used to be a "hidden pile of the Qianlong Group".

The paradox is that it is difficult for people of Yan Funing's level to break into some important research institutions in the United Kingdom, so Yan Funing's belonging to that department makes the upper echelons of Taijilong very entangled, so they simply chose to respect Yan Funing's choice.

Yan Funing himself had already made up his mind to return to China, for him, the Qianlong Group was far less safe than the Kanglong Group, anyway, with his ability, it was only a matter of time before he wanted to get into the top level of the Taiji Dragon, so he naturally had to choose the safest path.

Originally, Li Jiting had already agreed to his application, and then there was a "Black Death" thing at this juncture, so Li Jiting added a condition to him, and successfully completed the task of "Black Death", even if he successfully completed his internship and let him return to China, as for entering the "Flying Dragon Group" to engage in scientific research, or entering the "Kanglong Group" to engage in law enforcement, he chooses....

At first, Yan Funing disagreed, and even wrote several emails to the domestic bigwigs who admired him, who was also the chosen one, and presided over the mathematical research work of the Flying Dragon Group, but Li Jiting just took out one thing he did when he was a child, and easily forced him to comply.

Whenever he remembered that Li Jiting pretended to casually mention that old incident, Yan Funing hated to kill Li Jiting immediately, but he knew that he lacked such strength at present, and could only believe that Li Jiting would keep his promise.

But will he really?

Yan Funing didn't know, but he would find a way to make him have to comply.

He looked up at the black sign "Aedificium edificium biology" hanging on the other side of the hole door in the hallway, and thought to himself.

———————————————————

Oxford University's biomedical engineering, biophysics, biochemistry, life science base classes, molecular biology, medicine and pharmacy are in the forefront of the world, and the research of individual disciplines can be said to be among the best, not inferior to the current genetic research of the strongest United States, the reason for this is not only the strong research strength of the United Kingdom itself, but also the United Kingdom and the United States are originally a country wearing a pair of pants, compared with Europe with a strip of water, in fact, the relationship between the United Kingdom and the United States is closer.

This is not only because of the similarity of the cultural and historical traditions of the two countries, but also because the two countries are natural allies geographically, although the empire of the sun never sets in the era of dominating the world and the United States conflicted, but in the end the two countries still peacefully completed the handover of hegemony, and the two countries have also formed a "special" alliance relationship, all along, Britain has been the most trusted, reliable and capable ally of the United States.

As a result, much of the research is shared between the United States and the United Kingdom.

However, Yan Funing managed to infiltrate the Wanling Academy this time, not because he coveted these secrets that were difficult for him to access, but because the people of the Qianlong Group discovered that the "Black Death" seemed to have a connection with an important person in the Wanling Academy.

And Li Jiting's task for Yan Funing is to contact this important person and find a way to get some secrets out of the other party's mouth, whether it is a threat or a temptation, whether it is the secret of the Academy of All Souls or the secret of the Black Death.....

At this moment, Yan Funing is ready to try his luck in the biology building, the other party is a genius in biological genetics, and naturally he is also an academic madman, there is a great possibility of doing experiments in the laboratory on weekends, if he is lucky, maybe he will be able to contact the other party today, and it is not impossible to even complete the task.

However, it seems that his luck is not so good, because the first floor knows that there is no laboratory at a glance, and now Yan Funing has walked to the second floor of the biological building, and the entire corridor is silent, which is completely different from the quaint first floor, the decoration on this side is very modern, and the doors and windows have all become alloy doors and windows, and they are very tightly sealed. The marble in the hallway is also brand new, and the sides are no longer equipped with wall lamps, but with fluorescent lamps in the ceiling of the hallway, and there is not a single ray of light coming through the frosted windows in the rooms on either side.

The carrier in the shielded state could not even use the map, so Yan Funing could only stop slightly, glance to the right, and observe the metal nameplates on the alloy doors on both sides of the corridor to see if there was a "biological laboratory" in it.

He didn't dare to stay at the staircase for longer, he could only make a judgment in a limited few seconds, whether to explore this floor or not, for Yan Funing, there was only one chance, and choosing this floor meant that he couldn't go to other floors, because going to more floors would definitely arouse the suspicion of the guards sitting in the monitoring room.

At this time, Yan Funing had already seen the last two doors on the left side of the corridor on the second floor with the words "Biological Laboratory" in black flowers on a gold background, Yan Funing's Latin vocabulary was limited, but fortunately, there was basically no difference between the English and Latin words of "Biological Laboratory", and Latin itself was equivalent to English Chinese, so Yan Funing couldn't miss it.

However, there seemed to be no light leaking out of the door and window of the laboratory at the end, which made Yan Funing a little entangled, but Yan Funing didn't have time to think about it for too long, he finally chose to continue to go up, and the situation was even worse when he walked to the third floor, the whole floor was pasted with the sign of "laboratory", and the prefixes were varied, and Yan Funing's Latin vocabulary could not be distinguished one by one.

He only recognized a "microbiology laboratory", a "molecular biology laboratory" and an "animal laboratory", and he didn't recognize the other several rooms with laboratory signs, not only that, but there was no light on this floor except for fluorescent lamps, and no light came out of the windows of the laboratory, which made Yan Funing wonder if all the people from Wanling Academy went to the formal dinner in the academy today, and no one was engaged in scientific research in the laboratory.

Yan Funing was entangled again, there was only one floor above, in case there was no laboratory upstairs, then he would probably come in vain today, and the next time he could enter the Ten Thousand Souls Academy would be a matter of the Year of the Monkey, and he could only approach the target through other means, but the tragedy was that Li Jiting did not give him that much time.

After a little hesitation, Yan Funing still chose to trust his own judgment, he didn't see the light, although the windows of some laboratories may have closed the curtains, but the lights in the preparation room were not on, which was really unscientific, and he didn't see the three letters "DNA" he wanted to see.

Yan Funing decided that he could only go to the fourth layer to try his luck, and if he didn't, he could only give up, enter a random laboratory, pretend to take something, and then return the same way, returning to the body.

He walked up quickly, the staircase and the decoration of the laboratory floor formed a strong contrast, so that he had a feeling of passing through, the corridor side is modern, and the staircase side is medieval, the stone staircase is very narrow, if it is head-on up and down, you must turn sideways to pass, an iron tubular handrail installed on the wall has been polished very smooth, shining in the dim light, the stone steps should have been repaired several times, some steps are darker in color, the edge of the gap will be slightly more, some steps are lighter in color, there are no signs of wear on them。

Yan Funing's mood was still very calm when he walked up, even if he didn't achieve his goal, everything went smoothly and he didn't encounter any setbacks, but when he walked to the corner of the third and fourth floors, he looked up and found that it was bad, because the entire fourth floor was closed, and at the end of the stairs was a fully enclosed alloy door, and unlike the laboratory on the second and third floors, this alloy door was equipped with access control, and the silver alloy door was equipped with a pitch-black electronic lock on the side of the stairs, the lock had no door handle, only two digital buttons were flashing faintly.

There was no name of the laboratory on the door, only a number "6", the number 6 is really strange to be posted here, according to Yan Funing's memory, this can neither be the sixth building, nor the sixth floor, let alone the sixth laboratory.

Yan Funing's heartbeat suddenly accelerated, he didn't look at the monitor facing him at the door of the fourth floor, but his brain was running rapidly, thinking about what he should do, he grabbed the iron pipe handrail on his side with one hand, and slowly walked up, but no matter how he delayed the time, there were only nine stairs to climb when he reached the fourth floor.

Yan Funing's heart was shocked, the number of floors of this section of stairs from the corner to the fourth floor seemed to be different, this section of stairs was made of brand new stones, not like the staircase steps below were new and old, and the number of steps seemed to be different, the stairs below were all eight steps, but this last section had nine steps, and there was one more step.

"6,9,8" The three numbers are running rapidly in Yan Funing's mind, but he doesn't have much time to think about the relationship between these three numbers, at this time he has stood in front of the electronic lock, and it is a little strange that generally speaking, the number "0-9" on the electronic lock plus the asterisk and pound button are distributed in three or four rows, which is more reasonable.

But at present, the button of this combination lock is indeed in two distributions, and there are no asterisks and pound signs, these clues seem to point to the password to unlock this combination lock, so countless numbers are like meteors in Yan Funing's mind, falling towards his heart, Hugo once said that human beings have three keys, one to open the letter, one to open the note, and one is to open the number.

Thoughts, fantasies, and knowledge are there.

Yan Funing felt that what Hugo said was inaccurate, numbers actually encompass all this, everything is numbers, if he wants to choose the most magical one of the numbers, he will definitely choose "π", this number is endless and will never be repeated, that is to say, there are countless possibilities in this string of numbers.

One of its parts must have your birthday, one of its parts must have your bank password, and even one of its parts must have your ID number.....

If you convert these numbers into letters, you can get countless words and countless combinations, maybe the story of your life can be expressed in this string of numbers, this is a string of numbers with infinite possibilities, this is a circle, this number is the most representative of the universe.....

And all the passwords he used were all taken from one of the "π", so what kind of password would the other party use?

Yan Funing's hand had been raised and placed on top of the combination lock, his eyes were staring at the black button with a faint blue light at the bottom without blinking, if the carrier could sweat, he must have been sweating profusely at this moment, "6.....6.....6!"

Yan Funing touched the middle finger of his right hand to the top of "6", and a string of numbers flashed in his heart in an instant. He steadied his breath, moved his finger to the top of the "8", pressed it gently, and the first asterisk flashed on the display of the combination lock, then he pressed "1", then he pressed "2", and finally "8.......

The sound of the electronic lock "tick", the sound slid to the side, Yan Funing quietly breathed a sigh of relief in his heart, sure enough, the password set by the other party is "Perfect number", the so-called perfect number is the sum of the divisor in addition to itself, which happens to be itself, such as 6 = 1 + 2 + 3, 28 = 1 + 2 + 4 + 7 + 14, the next third number is 496, and then the next one is 8128, and then the next one is 33550336, so far, people have only found 48 perfect numbers.

Yan Funing wasn't sure if the other party must be using "8128", but he felt that if the owner of this laboratory was the target person, maybe he would use this number, and the clues on this floor did point to the number "8128".

Now it seems that he guessed correctly.

Yan Funing walked into the room, the fluorescent lamp illuminated the inside very brightly, but he didn't have time to look at the whole room when he heard a soft sound behind him, Yan Funing looked back, the alloy door had been gently closed, and there was a big note posted on the back of the door, which was written in English: "Please change into a sterile suit, bring sterile latex gloves and a disposable sterile hat." ”

The inscription below is Hugh Grosvenor, a descendant of the Black Prince.
