"Cheng Li, your location is in Room 19, Dinglie, Kun District, sit down after entering, and don't run around at will, otherwise you will be qualified for the assessment. ”

After Cheng Li got a token from the hand of a person who looked like a deacon in the examination room, he walked towards his position according to the position he specified.

This venue is divided into 8 districts according to the 8 hexagrams of the innate gossip.

The Kun district faces north, in the area directly above. Then each area is divided into ten columns according to A, B, C, D, pentohylheptoxin, and nondecan.

Each column has 1,000 rooms for players to enter.

Cheng Li calculated a little, and found that since this way, this venue can accommodate 80,000 people for the exam, and he couldn't help but feel a little embarrassed, he still underestimated the scale of this yin-yang arithmetic exam.

Of these 80,000 people, only 10 people were selected in the end, which is as difficult as you can imagine.

"You say, which 10 people will be able to enter the top ten this time and be qualified to enter the Yin-Yang Society?"

Cheng Li walked all the way, and there were voices everywhere talking about this arithmetic competition.

"First of all, Fang Xiaochun from the seedling class A, she is the granddaughter of the old man, this talent for yin and yang arithmetic can no longer be described as terrifying, basically it can be said that she is determined to win the first place in this competition. There was a man who was adamant.

"Indeed, Fang Xiaochun also participated in the competition this time, no one should be able to compare with her, even if those senior students are more advanced in cultivation than her, but when it comes to yin and yang arithmetic, they are still far inferior to her. Someone immediately chimed in.

"Fang Xiaochun?" Hearing this name, Cheng Li couldn't help but think of the three-free little Lori he saw when he first entered Class A.

"She's so powerful. Cheng Li exclaimed in his heart.

At this time, another person said: "Don't forget, there is also Wang Tianyu." ”

As soon as he heard Wang Tianyu, a nasty person, Cheng Li couldn't help but slow down his pace.

"In terms of talent, I'm afraid only Wang Tianyu can compete with Fang Xiaochun, and Wang Tianyu's father is the envoy of the Yin and Yang Society, which can be regarded as a family history. Although Wang Tianyu and Fang Xiaochun are both Miao level students, their attainments in yin and yang arithmetic alone are already comparable to others. ”

After listening to this, Cheng Li couldn't help but secretly say: "Sure enough, it's a pit father's son, it's really boring." ”

Feeling bored, Cheng Li quickened his pace.

Soon Cheng Li found his room and walked in, but what made Cheng Li strange was that this was talking about the room, but the actual surroundings were unobstructed, without any walls, only an area about 2 meters long was pasted on the ground with a talisman seal, and then a long table was placed in the area, and everyone sat on the ground in front of the table.

Cheng Li could even see any detail on the table of a candidate sitting next to him very clearly.

"You can see it so clearly on the left and right, so don't you copy it as much as you want?"

Just as Cheng Li was thinking this, the majestic voice of the Great Elder came from the examination room.

"The 87th Yin-Yang Arithmetic Competition has officially begun. ”

As soon as the words fell, Cheng Li found that a light flashed around him, and from the talisman seals attached to the ground around him, soft light continued to emit one after another, and these lights rose along the lines drawn around, and soon a square light curtain appeared around Cheng Li, like a wall, covering Cheng Li entirely.

Then from these light curtains, layers of white mist were emitted, and after a while, Cheng Li was surrounded by a wall formed by a layer of white mist, the white mist was very thick, Cheng Li looked over, and he couldn't see through any of it.

Cheng Li couldn't help but sigh in his heart: "The means used by cultivators to prevent cheating are also so characteristic of cultivating immortals. ”

Then on the table in front of Cheng Li, there was originally nothing, but now in a burst of spiritual pattern fluctuations, an antique test paper scroll appeared, and the four treasures of the study came out.

This test paper is encapsulated with a scroll, and after Cheng Li unfolded the scroll, he saw a large number of test questions appearing on it.

Cheng Li immediately read the test paper with full attention, and then picked up the pen and ink and began to do the questions.

"The first question: ask, the mathematical relationship between yin and yang and innate gossip. ”

When Cheng Li saw this, he couldn't help but wonder in his heart: "This ...... The style of the test paper produced by the cultivator is not the same as he imagined. ”

At the beginning of Cheng Li's thoughts, after all, it is the world of cultivation, and the test papers must also be in classical Chinese, which is extremely mysterious, and it is very difficult to speak. Like the books he read yesterday, they are all very mysterious, fortunately, his literary skills when he was a student were not bad, so he can barely understand it, but I didn't expect today's test paper to be so vernacular.

But later, Cheng Li thought that it was the same, after all, this exam was open to everyone, and those mortals who did not awaken the spiritual root would definitely not be able to understand those mysterious words, so the exam organizers deliberately used the vernacular to do the exam questions.

Thinking of this, Cheng Li said secretly: "The organizer of this arithmetic competition is also concerned. ”

Then he started working on the questions.

"Yin and Yang are binary mathematics, Yin is 0, and Yang is 1. ”

"Innate Bagua is octal mathematics, and each hexagram is composed of yin '--' or yang '-'. That is, Bagua and Yin and Yang can be converted into each other. ”

"For example, the Qiangua is composed of 3 yang lines to form a 'three' shape, which is Yang Yang Yang, that is, 111, which is 7 in decimal mathematics. ”

That is, binary mathematics is yin and yang yin (010) = octal mathematics is dry (7) = decimal mathematics is geng (7). ”

Writing this, Cheng Li seemed to think of something, and deliberately wrote a new line of words at the top.

"0 and 1 are my self-created characters, 0 is zero, 1 is one, 2 is 貳, 3 is three ......"

This world is not the earth after all, and there can be no such thing as Arabic numerals.

Therefore, Cheng Li deliberately marked the numerical correspondence between Arabic numerals and Chinese characters.

The simplicity of Arabic numerals is extremely important for programming, so Cheng Li did not hesitate to get out the Arabic numerals first.

After writing this sentence, Cheng Li continued to write the question.

To sum up, the mathematical relationship between yin and yang and innate gossip is as follows. ”

"Kun hexagram, for yin yin yin (000), is equal to decimal 0. ”

"The hexagram is yin and yang (001), which is equal to decimal 1. ”

"Kan hexagram, for yin and yang yin (010), is equal to decimal 2. ”

"Xun hexagram, for yin and yang yang (011), is equal to decimal 3. ”

"The hexagram is yang, yin and yin (100), which is equal to 4 in the decimal system. ”

"The hexagram is yang yin and yang (101), which is equal to decimal 5. ”

"The hexagram is yang, yang and yin (110), which is equal to 6 in the decimal system. ”

"The Qiangua, for Yang Yang Yang (111), is equal to 7 in the decimal system. ”
