At the special operations headquarters, Aoki sat on the main seat, opened a Kangxi dictionary at random, and looked it up. Watanabe Ichiro also picked up a yellow code book, and after putting it down, there was still a camera and a pocket watch on the table, and then Manna took out a pen from it, unscrewed the back cover, handed it to Aoki, and said with a smile: "These are all seized from the captured people." ”

Aoki looked at it, then lost interest, shook his head and said, "It's all some old tricks, can't it be a little fresh?" ”

At the Shanghai underground station of the military command, Song Mian took the telegram he had just collected, and after reading it, he said dejectedly: "All our secret liaison stations and radio stations in Shanghai have been destroyed by the special operations headquarters. He slapped the document on the table and said angrily: "The key is the code, which has been deciphered by them, and this time we have suffered heavy losses." ”

Pressing his hands on the table, he shook his head, sighed, and said, "I didn't expect the devil to use Feng Manna so much, this Feng Manna has become our opponent." ”

"Report!" Song Mian replied, and Lan Rouge came over, handed the report directly to Song Mian, and said, "Chongqing emergency call!" Song Mian took it, opened it and looked at it, and Manna then said: "Shangfeng strictly ordered us to quickly rebuild the urban liaison station and restore the radio station. ”

Song Mian did nod and said, "The stationmaster secretly left several liaison stations and radio stations in Shanghai, which can be activated now, but for now, the key is to find a way." Shake the codebook in his hand, "Send this codebook into the city, this codebook uses the new technology of foreign devils, and this foreign devils have eaten our secret losses, so that we have taken a big advantage." ”

Blue Rouge nodded and asked, "Does the devil know?" ”

Song Mian said with a smile: "According to the information we have so far, they shouldn't know yet, so oh we have to put it into use as soon as possible, and find a way to send this codebook into the city as soon as possible." ”

Blue Rouge smiled and said: "This is very easy, you give it to me, and I will memorize all the passwords in my mind, so that I don't need to bring the codebook, and I will be responsible for passing the password." ”

Song Mian shook his head and said, "In case you fall into the hands of the devil, under the torture of the devil, there is a possibility of telling the password." Resulting in the destruction of the entire Shanghai station, it is necessary to use other means to carry the password into the city to facilitate timely destruction. "It's a pity that what they don't know is that this operation is not so important at all, it is just a part of the plan to go up, and they are just a few small chess pieces in the plan. It doesn't matter at all whether it's dead or alive.

At this time, several people who were eating were all sad, only Rouge was eating alone, and suddenly saw several people staring at him, and asked puzzledly: "Don't eat, what are you staring at me?" Do I have flowers on my face? ”

A girl who had a good relationship with her said, "Why? Wait until you figure it out! ”

Manna did smile and asked, "Why am I all thinking about it?" ”

The woman sighed and said, "Among us, you are the most flexible and intelligent, if you can't think of it, there will be no hope for us for a long time." ”

Several other people also nodded in agreement, and then a staff member said: "Yes, if the code book can't be sent out in time, then all the combined cargo stations in Shanghai will be paralyzed." Zhang Guosheng said: "Smith's codebook is the only one that can be used, in case it is discovered by the devils, it is impossible for us to have a backup password for at least a few months." ”

The other person also nodded and said, "So, there must be no mistakes." At this time, Lan Rouge thought to himself: If it is useless to say that the sky has changed, can't you say something that has made achievements? Speak; "Pick up useful said. We all understand and know those truths! ”

Several people remained silent, picked up the steamed buns, and ate them, Rouge thought to himself: I won't talk about it now, but is it possible? It's all up to me, when will I be able to figure it out? He knocked on the table with his chopsticks and said, "Say! Don't stop, just throw bricks and stones. ”

looked at the few people who were pretending to be deaf and dumb, slapped the table, and said solemnly: "Say! Everyone has to say one! ”

Zhang Guosheng held back for a long time and said, "There is." Several people looked at him with hope, "wrote a small note and stuffed it into the steamed bun," and after hearing his statement, several people suddenly looked like deflated balls. Then the other man put his foot on the stool and said, "Hide the password in the shoe." ”

Manna said in disgust, "Put your feet down and eat?" The man smiled apologetically and put his foot down.

Manna anxiously asked, "Can you get something fresh?" ”

The girl who had been peeling the egg skin had not spoken, suddenly said, "If only we could write the code on the egg whites while the eggshells were still there!" ”

Manna stared at the egg that had been peeled off the shell, and suddenly fell into deep thought, and suddenly remembered that when she was in college, a professor once did an interesting experiment, at that time, because he was not interested in the theory at all, he fell asleep in a daze, and when she woke up, the professor had stopped talking about the theory and started experimenting.

Then he took out an egg from his pocket, took out the white vinegar and wrote a few words on the egg shell, asked a few classmates to look at it carefully, and asked, "Do you remember the words I wrote just now?" ”

Several students nodded and said, "Remember, that's good!" "Now do you see if the words are still there? Those classmates took a closer look and found that they couldn't see the words they had just written. The professor smiled and said: Vinegar is easy to volatile, and everyone must know this truth, so these are not the point. The point is that after I cook the eggs, you'll see what weird happens.

So he put the eggs in a beaker, heated them with an alcohol lamp through an asbestos net, boiled them, and when the eggs boiled, the professor took them out, and when the eggs had cooled, he said, "Do you remember when I first wrote in vinegar?" ”

"Return the motherland!" The professor nodded with satisfaction and said, "Okay, next I ask a student to peel this egg, and something incredible will happen." Many people were puzzled when they heard this, their eyes widened, and they stared at the egg in the student's hand, and then everyone looked at the egg in amazement, because four words appeared on the egg, to serve the motherland.

Lan Rouge, who woke up at that time, was also surprised, and later understood the principle, but in the eyes of many people at the time, he thought it was very interesting, and then slapped the table and said with a smile: "This idea is good, it is worth trying." ”

The woman was taken aback and asked, "Rouge, no!" This...... Can this really be done? ”
