"Don't worry about whether I can learn it or not, you just teach me." Yuan Mingzhu thought it was fun, so she pestered Lu Ming and said.

"Okay, first of all you have to read the books yourself, I will find you some books on the principles of cryptography in the past two days." Lu Ming agreed.

He wished Yuan Mingzhu would be fascinated by cryptography, so that she wouldn't have to worry about her accidentally discovering Ziyuan.

He never expected that it was an unintentional move to get rid of Yuan Mingzhu's entanglement, and later he created a first-generation master of cryptography in China.This is something.

Only Lu Ming, Huang Yanning and Sheng Youde knew the truth about the series of things that happened to Yuan Ziyuan, and even Sheng Di was kept in the dark.

Lu Ming knows that this matter will not be kept secret for long, and everyone will know soon, so it is especially important to hurry up now.

Yuan Mingzhu knew that she had misunderstood Lu Ming, so she was a little embarrassed and felt guilty, because it also wronged her own sister.

In order to make up for it, she hugged Lu Ming intimately for a long time, and she really showed her face, making Lu Ming almost lose control.

"I said Miss, save your energy and use it when we get married and have a baby." Lu Ming hurriedly stopped.

"Damn, who wants to have a baby with you." Yuan Mingzhu was so ashamed that she couldn't lift her head.

"What do you want to do if you're married and don't have children?" Lu Ming teased her.

"No, I just won't give birth, you let Du Juan give birth to you." Yuan Mingzhu said coquettishly and madly.

"Why did it get around to Du Juan again? This matter has nothing to do with others." Lu Ming looked helpless.

Du Juan came back two days ago, took some of her belongings, and moved to the dormitory arranged by the company.Du Juan's life has a new vision, and he is very excited spiritually.

For Lu Ming, the matter of Du Juan is the end of the story.Du Juan starts a new life, finds his lover, and builds his own happy family.

Maybe Du Juan is someone Lu Ming can't forget, especially for Du Juan, but the two of them can only go so far.To become a good friend, at most to rise to a confidant, it depends on fate.

Lu Ming never had any unreasonable thoughts about Du Juan, even though he put his first kiss on Du Juan's red lips and took away Du Juan's first kiss, perhaps this is the greatest fate between the two.

A couple who are in love may not have a happy ending, not to mention that Du Juan is only in unrequited love. For the two of them, the current result may be the best ending.

"By the way, you said that Cailian and Zhang Ziyang live together every day and don't get married. What does that sound like?" Yuan Mingzhu suddenly turned the conversation to Zhang Ziyang and Cailian.

"If you are really bored, you can go dancing with Ning Xiner, or read a few novels by yourself, why do you care about their business?" Lu Ming smiled wryly.

"I just think Zhang Ziyang is shameless. He eats Sister Cailian and lives with Sister Cailian, but he doesn't marry Sister Cailian. Isn't that shameless?" Yuan Mingzhu said angrily.

In fact, Lu Ming didn't approve of Zhang Ziyang's living at Cailian's place. Is that necessary? It's not like he doesn't have a place to live.He and Yuan Mingzhu had already made an engagement, and they could hold a wedding at any time, and they didn't say they would live together.

However, both Zhang Ziyang and Cailian were his best friends, so he couldn't discuss it too much. He felt that this kind of thing was just like a fish drinking water, and he knew how warm and cold he was, so outsiders were not qualified to comment.

"I'm worried that they will just procrastinate like this. Women age quickly every day. If Zhang Ziyang changes his mind one day and falls in love with someone else, you say that Sister Cailian should not jump off a building or swallow gold." Yuan Mingzhu said worriedly.

"Miss, don't worry about Cailian. Although Cailian is a woman, she has a manly temperament. Don't say that Zhang Ziyang will not change his mind. Even if Zhang Ziyang does change his heart, Cailian will not lose himself." Lu Ming said to Cailian had always looked at her differently, but he just said that if Zhang Ziyang really changed his mind, it would be unimaginable.

"Men just talk lightly, they just talk but don't do it." Yuan Mingzhu said angrily.

"Cailian is not Du Shiniang, and Zhang Ziyang is not Li Jia. Cailian is stronger than you. She will never jump into the river with a treasure chest in her arms. Don't worry." Lu Ming joked.

Lu Ming really admires Cailian, and thinks she is a real heroine among girls, but it's a pity that she fell into the business of Changsan Shuyu, but this business has produced many celebrities since ancient times.

For example, Hong Fu ran at night, Liang Hongyu who beat the drum to fight against the gold, Li Shishi who sacrificed his life for the country, Liu Rushi who helped his husband fight against the Qing Dynasty, etc., although they are all prostitutes, they are better than many famous officials who rushed to join the enemy when the country was ruined and their families were destroyed. Too strong.

Lu Ming doesn't think that when the country is ruined and the family is destroyed, everyone should commit suicide and die for the country. That's too extreme. They should live and have to live for revenge in the future. There is hope in the future. Revenge is the mission.

"Hmph, you are not a woman, and Zhang Ziyang is your friend, of course you helped him speak." Yuan Mingzhu said indignantly.

"When did I speak for Zhang Ziyang? I praised Cailian. I praised her as a hero among women and a husband of women." Lu Ming said with a smirk.

"Hmph, you guys are full of flirts, don't think I don't know." Yuan Mingzhu pouted.

Lu Ming shut up in time, otherwise, even if the debate lasted until tomorrow morning, he would not be able to argue for a whole day. In the end, he would have to admit that Yuan Mingzhu's fallacies and heresies are all correct, and every word and every word is the truth.

Women are the truth, at least in Lu Ming's case, if there is truth in the world.

Yuan Mingzhu talked about it for a long time. Seeing that Lu Ming didn't cooperate at all, she had to shut up boringly, but she was still a little proud, thinking that Lu Ming admitted that she couldn't talk to her, and surrendered.

Lu Ming and Yuan Mingzhu are both people who do what they say they can do. The two of them drove around all the bookstores in Shanghai.Cryptography is unpopular, and almost all bookstores have never bought such books. Finally, I found a foreign language bookstore opened by a Jew in a remote street and bought three books on cryptography.

One is "History and Principles of Cryptography" written by Niemansky, a Russian Jew. This is an entry-level book. Lu Ming thinks it is very suitable for Mingzhu. The second is "Ancient Cryptography" written by an unknown Italian. The Origin and Development of the Roman Code".

Lu Ming browsed through a few paragraphs, and found that this was a genuine book that he didn't dare to shout about. It was actually a cryptography course written by the Holy See.

Perhaps because he was afraid of being persecuted by the Holy See after the book was published, the author wrote the book under his name, and even used the title of ancient Rome as a shield to protect himself.

In fact, Western cryptography is based on the cryptography of the Holy See. The Holy See was the first to develop a mature and complete cryptography system because it needed to communicate with major dioceses.

This is also the world's first cryptographic system. Later, because of the generation and rapid application of the telegraph, cryptography began to flourish and develop vigorously in various countries.

Although the degree of perfection of cryptography in various countries is different, and the development paths are also different, but when traced back to the source, it can basically be attributed to the line of the Holy See.

Lu Ming decided to go back and study this book carefully. The words he used to deceive Mingzhu on a whim inspired him. He felt that it was necessary to master cryptography. In the future, he would communicate with the United States for a long time. Passwords are inevitable and a headache. question.

He didn't want the message he sent to be easily deciphered by radio amateurs all over the world. He wanted to establish a set of Lushi ciphers.
