Wu Tongguang said: "Yes, I know that he must be able to think of a way to open it." ”

Li Wutong said strangely: "What do you mean? Are you saying he still needs to 'want' a way to open? ”

"Yes, you reminded me."

"I reminded you?"

"When I was in the hospital, when I deduced that the eighteen characters were garbled, you said that since Li Qingfeng and Zhuo Shaoqing were a pair of partners, would this string of garbled characters be the exclusive encryption method for the two of them."

Li Wutong said: "Yes, it should be the exclusive way for the two of them." ”

"That's exactly the problem!"

Li Wutong was stunned by him.

Wu Tongguang said slowly: "Since the two of them are partners, why didn't Li Qingfeng come to Nanjing to directly hand over the information to Zhuo Shaoqing, but instead went around in such a big circle?" ”

The "going around a big circle" he refers to refers to Li Qingfeng handing over the cipher text, that is, the simple score of "Guiyan", to Zhuo Shaoqing, and handing over the mother copy of the correct character to Professor Zhu; When the password and the parent book converge, the translated sentences are still a bunch of garbled characters.

"You mean ......"

Wu Tongguang said categorically: "Yes, this shows that Li Qingfeng is no longer a liaison who trusts him 100%, that is, Lei Yin Zhuo Shaoqing!" ”

He continued: "In other words, for the information left by Li Qingfeng, Zhuo Shaoqing and we are actually standing on the same starting line, this is obviously Li Qingfeng's direct contact, if it weren't for his suspicions, what reason did Li Qingfeng have to lead Zhuo Shaoqing around such a big circle, wouldn't he just hand over the list to Zhuo Shaoqing?" ”

"Also, Zhuo Shaoqing hastily covered up the eight small characters 'Winter Attack Laishui' left by Li Qingfeng on the wall, not to protect this clue, but to create obstacles for us."

"Although the intelligence is a garbled code in the end, I believe that with Zhuo Shaoqing's intelligence, he will definitely be able to restore the truth."

When Li Wutong heard this, he almost wanted to beat Wu Tongguang: "You already know that Zhuo Shaoqing is a traitor, and you still give him your mother's book!" ”

Wu Tongguang said with a smile: "Since I dare to hand over my mother to him, I will naturally have a certain certainty, and if I expose him in person when I am in the hospital, he and Zheng Biwan will rob him, and the consequences will be unimaginable." It's nice to say that I'm going to get out alone, but you're still lying in a hospital bed......"

Li Wutong was not disgusted and said, "I dragged you down by saying this." ”

Wu Tongguang looked at the password box on the stone table intently, and said, "Since I dare to hand over the diary to Zhuo Shaoqing, then I believe that he can't take the list." ”

Li Wutong was happy in her heart, she had absolute confidence in Wu Tongguang, since he said this, he naturally had his deployment, so what did Wu Tongguang think, she couldn't figure it out when she broke her head.

Wu Tongguang continued: "Wutong, before handing over the diary to Zhuo Shaoqing, I have already cracked the password. ”

"Well done! Let's talk about it. Li Wutong said happily.

"I just converted the notes of "Guiyan" into numbers, and after eliminating the empty characters, I got 18 groups of numbers, and the Chinese characters corresponding to these 18 number groups were found in the mother book like this: 'Forward Count, Forward Smoke, Smoke Turned into Fire, Forward, Smoke, Smoke, Smoke, T

Li Wutong said: "Yes, but it's just a string of garbled codes." ”

Wu Tongguang said: "We also need to deal with this string of garbled characters. ”

"How to deal with it?"

"Many of those 18 numbers are repeated, and you try to eliminate the duplicate numbers."

Li Wutong did as he said, and eliminated the repeating number groups at the back and in front in turn, leaving only the eight number groups of 1231, 1653, 232, 21231, 1217, 4652, 4231, and 721.

"What kind of Chinese characters do you look at?"

"Hell, you've given all your diaries to 'Comrade Lei Yin', where can I rummage through Chinese characters?"

Wu Tongguang said with a smile: "You can find it from the 18 Chinese characters just now, 1231 corresponds to the 'former' character, and so on, you can just eliminate the same words in the 18 Chinese characters." ”

Li Wutong then tried, and found that after eliminating the repeated Chinese characters, it became "forward counting smoke and turning fire into fire." ”

"What does that mean?" Li Wutong was confused.

Wu Tongguang said: "If you turn this sentence upside down, you will know what Li Qingfeng wants to say." ”

The sentence is reversed, "Seek fire and turn into smoke, and move forward." ”

"This ......" Li Wutong still didn't understand.

Wu Tongguang said with a smile: "This is the password to open the password box!" Its sentence should be 'looking for fire to turn into smoke, counting forward', Li Qingfeng said like a lantern riddle, guess what will turn into smoke when it encounters fire, and such things are related to his latent actions. ”

Li Wutong thought for a moment and said, "There is, it's gunpowder!" His code name was 'Seeking Fire,' and he wanted to find out among the enemy's troops the 'gunpowder' buried in our army, and the 'gunpowder' turned into smoke when it encountered fire! ”

"That's right!"

"However, you just said that the password box is opened by typing a numeric password, what number does 'gunpowder' represent?"

Wu Tongguang said: "Gunpowder is one of China's four great inventions, and the first gunpowder was not used in weapons. The discovery of gunpowder originated from ancient alchemy, and the medicine king Sun Simiao wrote about the refining of an element in the process of alchemy, and this element is the main element of gunpowder, which is sulfur. ”

Li Wutong didn't interrupt him, and waited for him to continue.

"Sulfur is the substance that 'seeks fire to turn into smoke', and the following 'number forward' refers to the number represented by 'sulfur' to be counted one place forward!"

The order of sulfur in the periodic table is 16, which means that the password to open the password box is 15.

Reasoning to this point, Wu Tongguang sighed, when Shang Qingyuan died, he also used the numbers 8 and 0 to convey to Wu Tongguang that the order 80 in the Mendeleev element table was mercury, so that Wu Tongguang escaped Xiao Guodong's mercury base test.

Finally, the last layer of code has been deciphered!

Li Wutong let out a long breath, but after Zhuo Shaoqing defected, he cracked the password first and opened the password box in front of him.

Wu Tongguang looked at her with a worried face, knew what she was thinking, and said: "Silly girl, although Zhuo Shaoqing opened this box, what he took away was not the real list!" ”

"Really?" Li Wutong said excitedly.

Wu Tongguang gently touched the box, which was about three fingers thick, and it was obviously ironstone poured on the stone table. His nimble fingers touched the right edge of the box and found two small square spaces, each containing two pluckable beads with Arabic numerals engraved in embossing.

He gently turned the orb and turned the code to 15, only to hear a soft "click" sound, and the layer below the box opened.

A list of miniature films appeared in front of Wu Tongguang and Li Wutong.
