In the end, we could not convince the stubborn old man to abandon his plan to shoot and scatter the chickens and eggs, so we had to continue to walk all the way to the depths of the castle with irritation, regret and respect, and we crossed the library with millions of books, recorded the entire history of alchemy and various academic materials, walked around the alchemy experiment site with all kinds of incredible and magical props, housed all kinds of great ideas, and even ventured past the ruins that had been devastated by the battle and explosion, and experienced first-hand the unwavering will of the European Institute of Resistance......

"What the hell is going on!?" I yelled at the top of a staircase that was on the verge of collapse: "Why do you have only one floor of stairs here?

Didn't get physical reinforcement like me, Mickey and the others were even more unbearable than me, all of them were panting and sweating on their foreheads, and Sherdon, who was in the worst health, even simply pumped over, and could only be dragged by me like a dead dog, Mitchell squatted on the ground and gasped for a long time, and finally spoke "Ping...... This is not usually the case...... We used alchemy to develop a short-range jump teleporter and applied it to the stairs, so that no matter which floor you want to go to, you can reach it by taking one staircase......"

"Then now to defend against the invasion, turn off this device, right?" After so many years in the Institute of Asian Studies, I have long learned to be indifferent to all kinds of anti-heaven inventions, but there is still a doubt in my heart: "But we have dozens of floors to crawl around like this, right? How big is your place?"

"Instead of shutting down the device, it's activating the defense mechanism," McCourt added, "The random rearrangement of the two points of connection of all teleporters, i.e., the shuffling of the floors to which each staircase leads, is a defensive tactic that the European Institute has to adopt in the face of an irresistible intrusive force." ”

"What do you mean?" I jumped in my forehead, "In other words, you don't know which floor each staircase leads to, do you?"

Seeing that I wanted to get angry a little, Carl hurriedly played a round: "No, no, no, this is just a protection strategy formulated to delay the enemy's advance and gain time to counterattack, the connection between each floor is still the same, but the linear connection of the original three-dimensional space has changed to the radial connection of the four-dimensional space, and theoretically each radiant is within the coordinates of the space geometry......

I shook my head: "I didn't understand ......"

"In other words, the path to the bottom is still there, but the disrupted connections of the floors have lengthened the distance several times, and we will always get to where we want to go by moving forward, and the same is true for our enemies, so we must speed up and get to the warehouse before the enemies!"

"Then who can tell me how long we have to go?"

"That's a good calculation!" "The hairy boy Glebe jumped out: "The main body of the whole castle is eight floors, with four staircases on each floor, calculated according to the principle of probability and statistics, and the number of permutations and combinations that may occur after random arrangement is calculated by the formula of 32*31*30......"

"Enough is enough!" I interrupted the babbling bear kid with a twisted face: "I don't want to hear it!

The reason why I am so emotional is because the words of this unlucky child deeply touched the pain and regret that have been deeply buried in my heart for a long time: I think about how high-spirited I was when I just took the college entrance examination, I know astronomy and geography, humanities, physics and chemistry, and functional geometry is only idle, but it is the laziness and slackness of those years in college, so that the eighteen-year-old mastered the probability differentiation and was good at calculus "There are several ways to insert the boy and the four girls cut the line" I have become a twenty-two-year-old who has failed countless courses and can only play DOTA......

I couldn't get into graduate school and couldn't get into the civil service, I was abducted by Chen Sanshan to find a job in the talent market, and finally I was reduced to the point where I was exhausted and dealt with a bunch of crazy scientists every day, this is the price I paid for not insisting on studying hard, so sometimes I always wonder, what would it be like if I didn't skip class and go out to play games, but study hard? At least today, when Glebe threw out this series of formulas, we can say with disdain: "I will count this thing when you wear open crotch pants ...... this thing"

Seeing the self-pity on my face, Mickey also thought that I was desperate for the future, so he quickly encouraged me and said: "Wu, don't do this! You have to see the optimistic side! Every time we walk up the stairs, there is a theoretically 3.125 percent chance of reaching where we are going!"

It is indeed very exciting, I reluctantly mobilized my optimistic cells, excitedly thought, although we have climbed nearly 50 floors and have not reached the place we want to go, although the probability of going the wrong way is as high as 96.875%, but according to the general reverse probability calculation rule of probability statistics, the probability of us going wrong in the next layer is 1-96.875^50=?...... Forget it, let's go on, man, how can you be embarrassed to say that you have worked hard if you don't go down a hundred floors......

So I followed McCourt and the others to continue to climb up and down the labyrinth-like floors, I don't know how long I walked, during which Sheldon was relieved from the state of rolling his eyes, but when I heard that we were trying to climb a hundred floors, I immediately hummed and chirped and pretended to be a dead dog, refusing to get off my back and walk on my own, the only thing that is gratifying is that we didn't encounter a single enemy along the way, which is considered lucky, of course, it is not necessarily lucky, after all, with my level of mathematics, there is no way to calculate the probability of encountering an enemy in this situation……

"We succeeded! right away!" Walking into a hall again, Karl pointed to a statue of four white-bearded old men in robes in the center of the hall, and said to me excitedly: "This is the main entrance hall of the European Institute, and it is our main entrance and exit here! If you think of the floor where the Omega warehouse is located as a basement, this is the entrance on the first floor! We are only one step away from the basement!"

"Oh, is it?" I replied enthusiastically, but I knew in my heart that this fat man was just doing his best to cheer everyone on, and even a waste like me knew that if I walked the stairwell again, the probability of going to the basement and returning to the rooftop was the same......

"Bang!" Just when I was lazy and couldn't get motivated, the door of the main hall was suddenly knocked open, and a tall figure covered in blood pushed the door steadily.

I stared at each other for a long time as the two men who burst through the door saw a sense of absurdity come over me, and I asked, "I say, which of you can do the math, what is the probability that we will meet Statham's kid here?" )
