When Cheng Li was in college, as a student majoring in mathematics, he still had some understanding of some achievements in ancient Chinese mathematics, and he also did some research, and even wrote one or two papers on ancient Chinese mathematics.

Therefore, Cheng Li has a certain understanding of "Nine Chapters of Arithmetic".

Therefore, when he saw the first question, he recognized it at a glance, which was the first question of the first chapter of the nine chapters of arithmetic.

After confirming this matter, there was no doubt that a bombshell was dropped in Cheng Li's heart.

Since Cheng Li came to this world, he has been thinking about a question.

That is, whether there is a connection between this world and the original world.

Especially when he first saw that Reiki was composed of 0s and 1s in the shape of a solid body, Cheng Li even wondered if he had traveled to a certain game world.

But all the experiences that followed made Cheng Li dispel this suspicion, and this is undoubtedly an extremely real world. Even if it is said to have traveled into the computer world, then this is also a Tiandao brand computer.

So when a computer is powerful to the limit, there is no point in dwelling on the virtual and the real.

When he was on Earth, Cheng Li learned some theories about black hole computers.

At that time, there were already some theoretical conjectures in physics, and some models of the universe were constructed, some of which were models that imagined that the universe we live in was a huge computer, and the computing core of this computer was a black hole.

When the computer reaches the level of a black hole computer, or a Tiandao computer, information is matter, and matter is information, and the barrier between the two can be completely broken.

So Cheng Li was just puzzled at the time, and he quickly stopped worrying about whether he had traveled to a game world.

Because for him now, this world is real.

But he still wondered about one thing.

That's why are the entities that make up the aura 0 and 1 instead of other symbols?

Is there any special meaning between 0 and 1? Is it a coincidence of knowledge? Or is there some deeper reason behind it?

And this time, in the arithmetic monument, I saw the title of "Nine Chapters of Arithmetic", which made Cheng Li feel even more turbulent.

"Could it be that this world really has anything to do with the earth?" Cheng Li couldn't help but doubt in his heart.

In order to find out the truth, Cheng Li knocked on the side and asked the little arithmetic boy: "What? Can I answer this question is strange? This is just a very simple rectangular area calculation problem, there is a simple formula, rectangular area = wide * from." ”

"In the unit of measurement defined in the Qingling Sutra, 1 zhang = 10 feet, 1 foot = 10 inches, 1 step = 6 feet, 1 li = 300 steps = 1800 feet, and 240 square steps is one mu. ”

"So, there are fifteen steps wide, from sixteen steps, its area is 240 square steps, that is, 1 acre, is there any problem?"

Hearing Cheng Li say this, Xiao Shutong shook his head and said, "There is no problem, but when you answered the question just now, I can sense that you did not carry out the process of calculation." You know the answer to this question beforehand and answer it right away. Rather than calculating the answer to the question. ”

Cheng Li chuckled in his heart, this arithmetic tablet of the Heart Dao is really a bit powerful, and even this can be detected.

Then he listened to the little arithmetic boy and continued: "Originally, as I said before, according to the rules, answering the questions of the arithmetic tablet trial, it will not work just to rely on the back questions. The arithmetic tablet can detect whether you really know the solution to the question when you answer it, rather than just memorizing the answer.

"So you didn't have to say that the answer couldn't be passed without calculation, but the arithmetic tablet detected that you understood the solution to this problem. Your additional note just proves that, but that's what strikes me as strange. ”

"You know it's not strange how this problem is solved, and like you said, it's a very simple arithmetic problem. After all, it's just the first level of the problem and it's not too complicated, I'm just wondering, how could you have seen this topic beforehand. ”

Xiao Shutong looked at Cheng Li with some suspicion.

And Cheng Li said quietly: "I saw a fragment of the Sutra before, which recorded an identical question, so I answered the answer without thinking." ”

Xiao Shutong categorically denied: "This is impossible, this question comes from the sutra of another plane, not the product of this plane, you can't see it in advance." ”

"Another plane?" Cheng Li's breathing became a little short.

"Yes, the universe is so vast, and there are thousands of planes in the heavens and worlds. My arithmetic tablet is a natural thing, and the inside naturally collects the classic arithmetic scriptures in the thousands of planes of the heavens and worlds.

Then, according to the characteristics of the trialists, from the scriptures in the heavens and all worlds, some questions were randomly selected for the trialists to answer according to the degree of difficulty.

"Therefore, everyone who participates in the arithmetic tablet trial encounters different topics. And one of the most important features of the arithmetic tablet trial is that it will not extract the arithmetic scriptures that have appeared in this plane as the test questions. ”

"So, the first question you just answered is not a question that has arisen in this plane. Instead, it appears in another plane. This is how to ensure the uniqueness and fairness of the trial!"

Cheng Li immediately said hurriedly: "Then do you know which plane does the calculation of this question come from?"

Xiao Shutong shook his head and said: "I don't know this, although I am the instrument spirit of the Arithmetic Tablet, my autonomy is not too strong, and I need to rely on the master to a large extent." And the trial question bank of the arithmetic tablet involves such a profound level as the heavens and all worlds, and it is not something that can be interfered with in a young age like me now. All of this is done in the internal autonomous mechanism of the Arithmetic Monument.

"If there is someone who can completely answer the 10,000-layer question correctly and completely control the arithmetic tablet, it will be possible for me to insert the specific plane from which this topic comes from.

"However, although I don't know which plane this title comes from, I know very well that it can't come from this plane, which is limited by the rules. So, I'd like to ask you, where did you see the remnants of the Sutras, which happen to be exactly the same as those of another plane?"

Cheng Li's face changed rapidly, and finally he took a deep breath and said.

"Because, I'm not from this plane, I'm from the other plane you are talking about!"

After hearing this, Xiao Shutong fell directly from the air, he looked at Cheng Li in shock and exclaimed.

"What?, you're a plane traveler?!"
