What kind of existence is the major case in The Longest Day in Chang 'an?

In the novel, the big case technique helps the protagonist solve many things and makes the audience exclaim what kind of existence the big case technique is.

In fact, the author's design of this big case is indeed exaggerated in this play. There is also Xu Bin, the official of Jing 'an Department of Eight Products. It is incredible that a person can invent a major case handling program similar to a bug.

This transaction is simple and trivial, whether it is solving a case, looking for someone, or predicting the future. But in fact, if we explore the working principle of major cases, we will find deja vu. Because with the knowledge of modern people, we can regard it as a computer process. The user's input instructions are interpreted by the computer countless times, and a more accurate result is obtained, just like the big data that has recently become popular.

The invention of the major case technology in the play originated from the inventor Xu Bin's research on technical figures for many years, which enabled him to develop such a set of methods for processing archival data.

But in the Tang Dynasty, it was not easy to invent this. First of all, you should know all kinds of information all over the country, update the information status in time, and prevent calculation errors.

The traffic conditions and the speed of information exchange at that time were extremely unrealistic. Secondly, if you want to deduce the result, you must need a lot of paper to calculate it. With the productivity level of the Tang Dynasty, it was difficult for the government to support daily paper. Even if the government has the money to provide it, the supply of paper will inevitably be insufficient.

So why did the author fill this bug-like tool in this realistic novel? I think it's for the artistry of the novel. To attract readers with the tool of interpreting major cases is bound to have a good artistic effect, which was whimsical at that time in the Tang Dynasty.
