As soon as he saw Anne's adoring eyes at him, Yang Nianzhong was proud, leaned back on the sofa, looked at Anne and said with a laugh.

"Little trick, little trick, really when people all over the world are idiots, this little trick has a little life experience that everyone knows, and they all know the way to crack it."

As soon as she saw Yang Nianzhong's mouth, she didn't say how she found the secret on the paper, which made Anne very angry, sat down next to Yang Nianzhong, grabbed the soft flesh of Yang Nianzhong's soft underbelly, and made a 180-degree rotation.

Yang Nianzhong gasped in pain, slapped Annie's little hand, put his arm around Annie's shoulder, and said with a smile. "My silly girl, have you forgotten those chemistry lessons you learned as a child?"

"The tricks used by the so-called agents, our chemistry teachers have explained the principle to us, in fact, it is very simple, one is hot processing, one is acid and alkali neutralization."

"When I was a kid, I won the first prize in an experiment in a handicraft class, which was to chop and juice a lemon, then write my name on a cotton swab on a piece of paper, and when the paper was dry, I gave it to everyone to crack the secrets on the paper."

"But no one cracked it, but I didn't expect it to be cracked by my chemistry teacher with a cup of hot coffee."

Anne was interested at this time, and asked as she looked at Yang Nianzhong with wide eyes. "How did you find out? What exactly is the principle? ”

Yang Nianzhong smiled slightly, and pointed to the iron that was still energized on the coffee table. "It's very simple heat treatment, and you know that lemon is a natural preservative that dries quickly when applied to paper."

"But when the lemon-coated marks are heated at high temperatures, their chemical structure will change and the traces will remain on the paper, in fact, this is how the earliest agents used to deliver secret messages."

So that's the case, this time Anne is interested, every hotel room actually has a fruit basket with lemons in it, Anne found a blank piece of paper, squeezed lemon juice with a cotton swab to remove her makeup, dipped lemon juice on the blank paper to write her name on the blank paper and then blow dry.

Press it up with a hot iron and pull it gently, and sure enough, the letters written by lemon appeared, and the difference from the hidden diary font found in Yang Nian is that the newly made lemon juice font is darker, and the traces found in the blank space of the diary are lighter.

Maybe with the passage of time, the function of lemon juice has diminished, anyway, after heating, all the hidden words in the diary are revealed, and Anne began to translate to Yang Nianzhong.

In fact, the hidden part is very simple, it is the secret that this missionary Schneider does not want people to know, this Schneider is a descendant of the baron, of course, during the First World War, Germany was defeated, the emperor abdicated, and the nobles in Germany were not as beautiful as they were at the beginning.

Many of the privileges of the nobility were taken back, but you can't deny that the wealth that these nobles had accumulated over several lifetimes was enough for these children and grandchildren to squander. Because he could not inherit his father's title, Schneider was very fond of preaching, and at the age of 18, he went to Beiping, which had just overthrown the Manchu Dynasty and formed the Chinese government.

To say that it is a missionary is actually to come to the East under the guise of missionary work to seek excitement, this kid eats, drinks, prostitutes, gambles on everything except the real mission, and there is no one who is left behind, and there is a special mastery of what is there? That's collecting antiques.

At that time, the land of China was bullied by the Western powers, whether it was the end of the Qing Dynasty, the foreigners in the West did not dare to control these foreigners living in the East, who dared to clean him up? I know that he is breaking the law and making small moves, but you don't dare to catch him.

This boy relied on his brother to inherit the title, gave him money to support him in Beiping, and began to buy antiques on a large scale, and then transported them to Germany by ocean freighters to hand them over to his brother and store them in his own castle.

And in order to maintain his luxurious life, this kid is equivalent to buying these Chinese antiques at a low price and selling them at a high price to his stupid brother to make a profit. The boy knew that the situation was serious, and he reverted to his hypocritical pretense as a missionary, and ran back to Hong Kong, but he couldn't stay for a few years before Hong Kong fell.

This kid has been hanging around in Beijing for so many years, and he has bought treasures from the descendants of princes and nobles, and these superb treasures are all carried with him, and he will not sell them to that stupid brother.

The kid also fantasized about when he would save enough money to return to Germany with these priceless antiques, buy a piece of land, marry a wife, have a few children, and live a free life as a manor owner.

But I didn't expect that people are not as good as heaven, and as soon as they stabilized in Hong Kong, they were surrounded by the Japanese army and the British troops stationed in Hong Kong that year, and the cowhide blew loudly, and Hong Kong could not fall in their hands for a year and a half. But I didn't expect that after just ten days of fighting, the whole of Hong Kong was occupied by the Japanese army, and it was brutally ruled for more than three years.

As for this Schneider, it is not a problem to rely on the identity of the Germans, but the Japanese army was too greedy back then, and they knew that these foreigners had money, so they issued a very unacceptable order.

Westerners who ordered Hong Kong to leave Hong Kong were allowed to leave Hong Kong again, but although they could only carry 15 kilograms of luggage, including their passports, a small amount of cash, clothing, and toiletries, they were not allowed to carry the rest.

Whether you're a high-class person in Hong Kong, an American, a German, or a British, this kid was disguised as a missionary and built his own chapel in a small village in the countryside.

There is a big banyan tree behind the church, and there is a land temple next to it, after the Japanese army occupied Hong Kong, this kid packed his treasures in an iron box overnight and buried them under the big banyan tree in the open space behind the church.

I'm afraid that I forgot to make some lemon juice, and wrote in my notebook, the time, place, quantity, name and other important information of those treasures I buried.

So the question is, why did this Schneider appear in Hong Kong with his diary and his carry-on luggage on board an ocean freighter to return to Germany? It's very simple, this kid's luggage is overweight.

Then they were seized by the Japanese military police, and after opening the box and inspecting it, the Japanese were afraid that these Westerners would take away any evidence of their evil in Hong Kong, such as diaries and letters, and then destroy them all.

This Schneider carried this diary with him, which had a black cover on it, and a golden cross on it, all of which were detained, including the Bible, and the people were caught up with the ship, and the things were left.

The Japanese army destroyed the books and letters they had confiscated, but the number of Japanese soldiers was too small, and they were too lazy to do this kind of dirty work, so they handed over this kind of work to some Hong Kong people to complete.

The Hong Kong man who burned the books was illiterate, but he was a Catholic who saw the cross and the Bible. The boy couldn't bear to burn the Bibles, so he secretly hid them and took them out at work.

It was given to his son, who was a schoolboy, and brought the two books to his school library, where they were kept in the library's most secret book.

A few years ago, the library was renovated and these books were sold to those small traders and hawkers who bought antique books, and then they were bought back by Yang Jianzhong in the antique book store.
