"This is simple, is to take the word apart, for example, the word is composed of horizontal, vertical, apostrophe, point, fold, we can use special symbols instead" Liu Yuan finished speaking, picked up a line of brush and wrote Arabic numerals from 1 to 10 on the paper, and then explained: "This is called a number, is the abbreviated version of our one to pick up, this is a symbol that others do not know, such as horizontal as 1 to replace, stick to replace with 2, apostrophe with 3, point with 4 instead, fold with 5 instead, a [person] word can be split into a skimming and a point, Then replace it with 34, of course, this is still in the imagination, a bit messy, and it has to be slowly improved. ”

In addition, you can also use the stroke method to establish a font library, and write according to the strokes, such as a word with thirteen strokes, then write a thirteen, and then mark the first stroke and the last stroke to distinguish it; Or use the root, by the way, we can use the root, well, I can still memorize that root list, what, what is that root list, you don't know? That's right, I came up with it on my own, and I'll explain it to you. ”

Liu Yuan said a lot more, all about some skills in writing secret letters, thousands of years of accumulation, but it is really not blown, Li Er and Hou Junji listened to their eyes straight, Liu Yuan seemed to show them a world from the past, and couldn't help but admire Liu Yuan's whimsy.

"That's right" Liu Yuan suddenly remembered a wonderful method, and couldn't help but say excitedly: "Your Majesty, General Hou, I have an even more wonderful method." ”

"Oh, what a way, say it quickly." At this time, Li Erji heard that he was interested, and asked again and again.

Liu Yuan smiled: "Write the information in the egg, and use the egg to transmit the information." ”

It was a method invented by Germany in World War II, which used strong vinegar to write information on the surface of the egg, and then dried it before boiling and cooking. The word will seep into the inside of the egg, it can be said that it is seamless, no one can check it, in the Tang Dynasty, the chicken has been very common, the great poet Meng Haoran wrote in "The Old Man's Village": The old man has chicken millet and invited me to Tian's house. The green tree village is close to the edge, and the green mountain Guo is oblique outside. Open the noodle garden, and talk about the wine. Stay until the Double Ninth Day, and come to chrysanthemums. Among them, the chicken millet refers to. It is the chicken.

Eggs are available in the market, and although Dr. Nashizi does not eat "dirty" pork, he will occasionally eat a chicken or something after eating tired of mutton and game, so he said. Chickens are not rare, and eggs are not rare. At least. Li Er and Hou Junji knew what the egg was when they heard it.

When the soldiers are outside, once the food and grass are gone, don't say any pigs, chickens, dogs and cows, even the bark of trees have to be eaten, so the generals are not as arrogant as Wenchen.

Hou Junji asked curiously, "Use eggs to send intelligence?" Write the words on the outside, and there are many of them. They don't bother to check? When you encounter a rugged mountain road, a large cart of eggs is transported, bumps and bumps, isn't it easy to break? ”

"What kind of skill is that? Of course, the words were written on the inside of the eggshell, and they couldn't find them even with the lanterns. Liu Yuan said proudly.

"Written in it? Break the eggs open and close them back carefully? That's a bit unreliable, right? ”

Liu Yuan smiled and said: "No, the eggshell is not broken, it is intact, but the information has been written in the egg."

"Are you right, are you an immortal?" Li Er obviously didn't believe it, stared at Liu Yuan and said, "Liu Yuan, don't talk about it, be careful to cure you for the crime of bullying the king." ”

The shell of the chicken, when it is broken, can no longer be closed, and the shell is not broken but can write inside the egg, is it possible? Li Er asked himself if he was wise and martial, this Liu Yuan, still wanted to refer to the deer as a horse and treat himself as a faint king?

Liu Yuan hurriedly said: "Weichen doesn't dare, Your Majesty, the world is so big, there are no surprises, even if you can write in an egg, there is no need to be surprised." ”

Li Erle is happy, he is still hard-mouthed at this time, can he really do it if he is so good? Okay, let's see how you can fulfill this lie today, so I glanced at Liu Yuan and said with a straight face: "You are so sure, that's good, seeing is true, hearing is false, I ordered you to write in the egg, write it, and there will be a reward, if you can't do it, this will deceive the king, what are the consequences of bullying the king, do you know the truth?" ”

"Your Majesty, I don't know what to reward Weichen?" As soon as he heard that there was a reward, Liu Yuan immediately became energetic.

"What do you want?"

"Weichen got married on the sixth day of June, if the emperor gave me a lady as his wife, the minister would be grateful." Liu Yuan didn't think about it, and said immediately.

Last time there was a chance, Li Er wanted to fulfill Liu Yuan's wish, but Liu Yuan gave up the near and far, and did not let the household department Shangshu help, but asked Li Er to make an order to get rid of Du Sanniang's slavery, for this matter, Cui Jing's old boy almost turned against Liu Yuan, and he gave Liu Yuan a lot of face, and now there is such an opportunity, Liu Guo will not miss it.

The people of Cui's Mansion gave themselves the wild wolf and the blood knife as guards so generously this time, this love is great, and Cui Mengyao's heart is tied to herself, when she met, she was a high-ranking young lady, and she was just a lowly businessman in a small shop, it can be said that when you met in Wei, of course, it was her own "micro", even now the official rank is not high, but Cui Mengyao has always had no regrets, which made Liu Yuan very moved.

Women are also people, fame and fortune are a good thing, no one can refuse, the rich Cui Mengyao will not be lacking, Liu Yuan now has a family fortune of millions of taels, enough to make the people around him clothed and fed, that is, Liu Yuan is not good, Cui Jing, who is rich, is also very willing to let his daughter gnaw on the old, Qinghe Cui's family has a big business, how can it not be bad Cui Mengyao's mouth, now the bad is "Ronghua", that is, "name", if you get married, your wife is expensive by her husband, and there will be a lady of destiny immediately, among those little sisters, It's definitely a very face-saving thing.

Li Er nodded and said: "The appetite is not small, but with your merits, it is not too much, okay, if you can do it, I will answer you, if you lose"

"Let the emperor dispose of it." Liu Yuan said without hesitation.

"Okay, let's see what you do." Li Er still said with a look of disbelief.

Li Er has planned well, if Liu Yuan loses, he will collect the half of the lottery and the Chang'an newspaper, and the influence of the Chang'an newspaper has now attracted Li Er's attention, not to mention anything else, just a few newspapers will lure his Guanyin maid to not eat early, and read the newspaper with relish. She is also interested in talking to herself about those stories, which she couldn't see before, and she is a little unscrupulous about the queen's demeanor that she values most.

At Liu Yuan's request, Li Er asked people to bring a few eggs and a bottle of aged vinegar, and Liu Yuan, with Li Er's consent, dipped the vinegar with a new cigarette in the imperial study, and carefully wrote the eggs, and after writing, gently put them on the table. Wait for him to dry.

"Liu Yuan, didn't you say you wanted to boil? Are you going to go to the kitchen to get it, or will I have someone bring you a small one? Li Er's memory is good, and he remembered what Liu Yuan said.

"Your Majesty, no. Weichen wants you to see a miracle happen with your own eyes, all you need is a glass of water and a piece of paper. ”

"What do you want water and paper?"

Liu Yuan smiled confidently and said, "Your Majesty." Just look at it. ”

With Li Er's permission. Liu Yuan took a blank and thick piece of paper from the desk, folded it into a small pot, tore off the two threads from the clothes and tied them, poured water into them, and put the egg written in vinegar in the paper pot, and then in the surprised eyes of Li Er and Hou Junji. took out a fire fold from his arms, lit the candle on the side, and put the paper pot on the fire to burn it, to the surprise of Li Er and Hou Junji. The paper did not burn, but the water in the paper slowly began to tumble.

Hou Junji said in surprise: "This, what's going on?" Liu Yuan, do you know how to be immortal? Why is the paper not burning, but the water is boiling? ”

"This is very simple, that is, the heat of the fire has not had time to burn the paper, and the heat is transferred to the water inside, so it can't burn the paper."

Li Er was like a curious elementary school student, his eyes widened, his face was about to reach the paper pot, he looked at the pot with interest and asked curiously: "Liu Aiqing, what do you mean, this paper will not burn?" ”

Han one, where is this a celebrity emperor through the ages, it is clearly an uncle with a strong desire for knowledge, but Li Er's tone of being studious and inquisitive like a primary school student, Liu Yuan heard it for the first time, and Hou Junji also stared at the egg in the paper pot, he stared at the egg in the paper pot, as if he was afraid that the fire would burn the paper pot and the egg would fall and break, looking at his entangled face, Liu Yuan wanted to laugh.

It's not like a famous general.

In fact, stripped of the halo on his body, there is not much difference between people and people, they are both two shoulders and one head.

Liu Yuan hurriedly explained: "No, when the water in the paper pot is almost boiled, the water is boiled dry, and the heat cannot be transferred or the heat transfer is not timely, the paper pot will be burned." ”

Li Er and Hou Junji nodded secretly when they heard this, and now the two of them are becoming more and more confident in Liu Yuan's eggs, especially Li Er, who are all considering that on Liu Yuan's wedding day, it would be good to seal Cui Mengyao's husband

After about a cup of tea, the water in the paper pot had boiled nearly half, because the heat transfer was not enough, and the paper became a little brown because of overheating under the paper pot, but it never burned through, seeing that the time was almost up, Liu Yuan smiled, took the paper pot to the other side, and prepared to wait for the eggs to cool down a little.

"Liu Aiqing, is this okay?" Li Er looked at Liu Yuan, then at the egg in the paper pot, and said a little puzzled.

"Okay, Your Majesty, this chicken is still hot now, and when it is cold, please ask the emperor to do it himself, and see that he knows the dragon and the phoenix."

"Okay, I'll see if it's that magical." Li Er rubbed his hands excitedly, with an eager expression.

Liu Yuan has made a lot of contributions recently, and the Qinghe Cui family has made a great contribution, especially recently, the expenditure of the treasury is maintained by the household department, and the construction of the Daming Palace and the dredging of the river are the work of Cui Jing, the secretary of the Ministry of Industry, and Liu Yuan has been silently contributing, raising the training of the army, teaching the pressure box technique to the fine team, thinking of several ways to use secret letters to transmit information, repairing the Danfeng Chaoyang for the eldest grandson, etc., to be honest, even if Liu Yuan does not mention it, Cui Mengyao's title will not be less.

took out the things that originally needed to be given as a prize again, Li Er's abacus was not ordinary.

After waiting for a while, after Li Er got Liu Yuan's confirmation, he gently knocked the egg twice, and when the egg shell peeled off, he couldn't help but let out an "ah", and suddenly shouted out in surprise (to be continued......
