The host of Wenbi is the chief of the guard. He was not tall, with a silver mask on his face, and his exposed eyes seemed to have not woken up.

He ordered Luo Qianhuai and the others to step forward in turn, and looked at the row of things placed on the table in front of them. Coincidentally, these finger-length white jade chips, she is very familiar with them, and they are the ones that she gave to Mo Gongzi from the lead coffin.

There are twenty-one white jade chips, which are engraved with the heavenly and earthly branches, such as Gengzi, the words of Guiwei, but the lower part is a pattern or seal character, there are flowers, birds, insects and fish, and some are like people's names, and there are no certain rules.

However, after being allowed to watch for a few breaths, the jade chips were put away, and the four of them were brought to the table that had been laid out a long time ago, and sat down on their knees.

The exam questions have long been placed on the desk, and there are two in total:

One is to explain the use of jade chips according to their own understanding; Second, how to strengthen and improve the intelligence transmission work of the frost battalion.

Luo Qianhuai raised his eyes and looked at the other three people, and saw that their expressions were quite solemn, showing that the content of this literary test was also beyond their expectations.

She lowered her eyes, and in the flash of her thoughts, all kinds of thoughts came to her. I am very grateful to the various spy war TV series in her previous life, which brought her extremely rich intelligence work experience, even if she has never done it herself, she can still say the truth.

Problem 2 is as easy as finding something for her, but problem 1 is different. She has been getting these jade chips for a long time, and she has also seriously checked and thought about them, but she has no experience.

But if the whole question is just empty, not only will you miss the first place in the big competition, but it will not conform to the answering habits of Luo University.

Empty questions are absolutely impossible to be empty. Even if you really don't have a clue, you have to use neat handwriting to answer the paper seriously, and you may be able to get a few points if you analyze it reasonably.

Thinking of this, Luo Qianhuai decisively substituted the second question into question 1 and thought in this direction.

If these jade chips are also used to transmit information, then what will be their purpose?

The ten heavenly stems are in the front, and the twelve earthly branches are in the back, and there are a total of sixty combinations, which are used on top of the year, which happens to be one Jiazi.

But if you put it on intelligence work, that's certainly not the case. You can't pass on information only once a year, and what is the point of passing on a certain year in the past?

At this time, an article she had read in her previous life suddenly jumped into her mind.

It was a study on the development of ancient intelligence transmission, and she flipped through it in a magazine at the time, and she thought it was interesting, so she took a few more looks, and was quite impressed by one of the methods.

In order to prevent the information from being retained and revealing information, some clever people have come up with this method, which is to predict in advance forty or fifty situations that often occur and the orders that will be issued, such as floods, betrayals, troubles, assassinations, bribery, accumulation, and so on, and number them one by one.

For example, if the serial number of the assassination is ten, when passing on information, one should write a poem or a poem, or a letter or article, and put a black dot under the tenth word, and then imply the identity of the assassin in the poem, so that no one can guess that this is a murderous order.

Although the jade chips she received were few, it could be scientifically assumed that they were only part of a whole set, and that this whole set could also be assumed to refer to sixty situations or commands. As for why there is a pattern or text underneath, it can be seen as a more specific description or indication, such as who to use the counter-plot, what materials need to be procured, and so on.

Strange to say, along this line of thought, the more she writes, the more she feels it makes sense. If this is the case with the role of jade chips, then the method itself is slightly inferior to the one that is conveyed in poetry.

The reason is that this jade chip is too deliberate, and it will make people feel that there is a problem at first glance, while the poetry and family book is very natural, not easy to find, and it is easier to carry specific details.

Therefore, the one she saw in her previous life was the development and improvement on the basis of the jade chip in front of her.

But either of these two is considered to be encrypted to a certain extent, which is much more clever than straightforward writing.

Of course, both of these methods are unsatisfactory, and the content contained in them is too simple, and it is impossible to explain or deal with complex situations in detail, and it is still necessary to rely on the codebook to solve it completely.

The two sides designate a book as the secret code book, encrypt it digitally with the page number, and then decrypt it against the other party after transmission.

This method has been used a lot in spy war dramas in previous lives, but in the big Yu in front of him, if he borrows ten of their brains, he will definitely not be able to think of it.

But Luo Qianhuai didn't want to help people to the west. It doesn't matter what the purpose of the jade chips is, as long as they are written carefully and convince the examiners that they are used in this way.

On this basis, throwing out the poetry and grammar is amazing enough, and it is still worth the money when used to exchange for hundreds of cakes of gold.

When Huo Yi and the three of them handed over the papers, Luo Qianhuai was still immersed in writing a big book, writing more than a dozen bamboo slips on the desk.

Once the answer mode was turned on, Luo Qianhuai became extremely focused, ignoring everything around him.

Some people went out of the account, some people entered the account, some people silently filled up new bamboo slips for her, some people added new ink for her, and some people stood quietly beside her, looking at the content of her pen, showing an extremely surprised expression.

Luo Qianhuai put down the pen, habitually preparing to check it from beginning to end before handing in the paper, but someone's hand was faster, one step ahead of her, and put away the bamboo slips on the desk.

"Wei Lian." Wei Ying, who had been standing beside her, opened his mouth, and there was a slight trilling in his voice: "You did a good job, let's go out and rest for a while." ”

"Yes." Although Luo Qianhuai didn't know when he appeared, he relaxed from Fang Cai's nervous concentration, and did feel tired and hungry, and when he got up, he suddenly felt a little dizzy, and he shook involuntarily.

She shook her head, completely oblivious to the strange gaze of the Earth Guard Lord and the others, and walked out of the tent tremblingly.

It was midday, and it was noon, but everyone on the field was still standing honestly under the scorching sun, and no one left the venue halfway, and no one took out food to satisfy their hunger.

Luo Qianhuai approached Huo Yi, gently pulled his shirt, and asked quietly, "Brother Huo Yi, may I ask....... Will the eclipse be delivered later? ”

In the previous games, no matter how bad the contestants were at noon, they would send a boxed lunch, and she consciously asked this question as a matter of course.
