Entrance Examination (II)

The bright starry sky overhead is like a dream, and more than 20,000 people in the formation have no intention of appreciating, two-thirds of the exam time has passed, there is only one hour left, the people who are in the back of the eighty are catching up, and the people in the top eighty do not dare to slack off, for fear of being overtaken by the people behind, especially close to the passing line of eighty, the competition is quite cruel.

"Hey, I didn't expect that I, Ye, would also have a day through the back door. Ye Xiao is very unwilling, but he is helpless, if he is given a year to familiarize himself with the knowledge of this world, or to study the way of formation, the possibility of passing the test by himself is still very high, but unfortunately time is not waiting.

The number of stars in the sky is decreasing more and more slowly, partly because the remaining questions are becoming more and more difficult, and partly because many people at the bottom of the rankings have given up struggling.

Ye Xiao looked up at the starry sky in the sky, some areas were sparse, and some areas were still dense.

"I don't seem to have read the question of that area, the density of stars is the highest in the entire starry sky, it should be the most difficult area, but I don't know what type?" Ye Xiao broke the jar, and at the same time wanted to satisfy his curiosity. Set your sights on a star that is not too big or too small.

"Heavenly machine class, three-star difficulty, four points, the barbarian realm, the fairy realm, and the demon realm all have day and night, why are day and night born?"

Ye Xiao knew the answer the moment he saw the question, but he was not sure. "I deliberately noticed when I incarnated as Kunpeng in the formation of "Getaway" before when I traveled to the Savage Realm, the Savage Realm is no different from the earth and a sphere, and so on, the fairy realm and the demon realm should be planets, and the physical laws of the universe where they are located are all different from the earth, but they are not completely different. If I don't have enough aura, I still can't get rid of gravitational flight, which means that the difference between the two cosmic laws is aura. Which laws apply and which ones are the same is a question worth studying. ”

"The Three Realms are all spheres, and their rotation causes the ...... of day and night"

The four points were successfully obtained, but Ye Xiao's face became serious, "The people in the Three Realms are not as simple as I thought, they already have a full understanding of this universe, those great powers are omnipotent in the heavens and the earth, like the earth is a sphere, and the planets revolve around the perseverance, they may already know all this astronomical knowledge." ”

In order to verify what he thought in his heart, Ye Xiao once again set his eyes on a huge star.

"Heavenly machine class, seven-star difficulty, sixty-four points, how to measure the vast geometry of the wilderness realm?"

"Sure enough..."Ye Xiao knew that since this question appeared here, then there was an answer, and there were already people in the Three Realms who had mastered a lot of knowledge. The Barbarian Realm is so vast that it is almost impossible to map with human power, and this question is actually about how to measure the surface area of the planet in the Barbarian Realm.

The human beings on earth have given the answer to this question as early as the ancient Greeks. The ancient Greek scholar Eratosthenes was influenced by Aristotle's "Heaven" and was convinced that the earth was a sphere, and he chose two cities on the ground that were basically on a meridian from north to south. Alexandria and Aswan in Egypt, and then at noon on the day of the summer solstice, the sun exposure of the two wells was observed at the same time, and it was found that in Aswan, the sunlight could directly hit the bottom of the well, while in Alexandria, the sunlight could only hit the wall of the well, and the light had an angle of 7.2 degrees in the vertical direction of the wall of the well, and the reason for this angle was precisely because the ground in Alexandria and Aswan City presented curved surfaces.

Eratosthenes calculated the distance between the two cities based on the time the caravan spent on its way through the two cities. According to the geometric theorem, the circumference of the earth is calculated, and the surface area of the earth can also be obtained at the same time. Although there is a certain error between the calculation results and the real earth, it generally reveals the true size of the earth.

Ye Xiao concocted it in the same way and informed him of the calculation process, and Xingchen was silent for a long time before slowly disappearing and turning into Ye Xiao's points. "It's... Isn't it that these ambiguous answers are all determined by Mr. Mu himself? This is more than 20,000 people, and Mr. Mu can scruple at the same time!"

At the same time, Mu Chengshu, who was outside the Heavens Star Fighting Array, frowned, "Could it be that some of the little ghosts of the Mo family secretly ran down to play? ”

As the so-called lost mulberry elm in the east corner, Ye Xiao couldn't compete with these natives because he was born on the earth, but he didn't expect that because the knowledge he mastered from the earth was not useless, even though the physical rules of this world are different, there are still traces to follow, there is a way to follow, at least the mathematical logic still exists, and the π pi will not change because of the other world.

"Heavenly machine, eight-star difficulty, one hundred and twenty-eight points, the journey of the avenue, the speed of the line, even if the teleportation array is not teleportation, ask the extremely fast geometry?"

"My God, no, the people here even understand the principle of the invariance of the speed of light, this is the basis of the theory of relativity...... "All the teleportation arrays in the Three Realms, the teleportation charm is actually not instantaneous, and there is still a speed limit in it. However, the communication speed of the mother stone in Ye Xiao's hand is definitely faster than the speed of light, this Ye Xiao had done experiments when he was talking to Youyou before, "If it's not the speed of light, then what does the ultimate speed of this world have to do with it?" Ye Xiao instantly thought of the culprit who changed the physical laws of this world-aura.

"Heaven and earth have aura, and the spirit son is the foundation, and the ultimate speed of aura transmission may be the limit of this universe, which is different from the upper limit of the speed of light on the earth. If this is the case, then you can use the characteristics of the mother stone to measure, as long as the two people holding the mother stone are far enough away to have a certain time difference between the two soul calls, then the distance between the two divided by the time difference is the limit of the transmission speed of the mother stone, and this limit should be infinitely close to the extreme speed of the Tao. When Ye Xiao said the measurement method, he successfully scored this 128 points, and his ranking rose directly to more than 70.

Ye Xiao, who was obsessed with answering questions, didn't care about these, he just wanted to know what are the similarities and differences between this world and the world where the earth is located, and what is the level of mathematical knowledge in this world.

"This question is actually a math problem, and it is not very difficult, and it is worth eight points. When Ye Xiao slashed a four-star question again, the outside world was already boiling.

"Moved and moved, this person named Xiao Ye surpassed Mu Bufan!"

"Time is not over yet, the victory or defeat is still very uncomfortable, Mu Bufan still has hope!" The other person was more optimistic about the elixir genius Mu Bufan.

"It's a pity that Chu Hongchen and Yehua collided with each other's formation geniuses at the same time, and they responded to each other's results. Chu Tianji, who was onlookers, sighed, "Who is this Xiao Ye? Why can a third-class tribal kid be ranked first? What is he good at? This matter Chu Sleeve, you go to investigate clearly, if it is really a talent, we in White Tiger City must not let it go." ”

An old man beside Chu Tianji hurriedly promised, "Okay, master." "This person is the brother of Chu Yi, Chu Tianji's henchman, who has died, and Chu Yi has no choice but to reuse it, which can be regarded as compensation for them.
