The information sent back by Chen Guoyue to the Criminal Investigation Bureau is related to Li Guangping, and Cai Wenyue is keenly aware of the fact that there are definitely some problems with this laundry owner who suddenly became very generous. Because Chongming is still in the post-disaster reconstruction stage, and some time ago the government cracked down on the "gold diggers", there is no possibility of getting rich overnight, and the income from Li Guangping's laundry is simply not enough to support his recent extravagance.

The business in Li Guangping's store is still the same as before, but he suddenly became rich, which can only show that this guy has recently made a windfall, and the origin of this windfall may be an important clue.

"Li Guangping's main client is the ...... of the Dongtan International Conference," Cai Wenyue thought of this, and suddenly a clue was connected in his mind, and he picked up the phone on the table again and dialed the number that had just called.

"Boss." Chen Guoyue's voice came from the other end of the phone, and when he was outside, Cai Wenyue asked him not to address the director and other words, so as not to accidentally reveal his identity.

"There is a detail I forgot to tell you just now, when you are staring at Li Guangping, you should pay attention to see if he has any intersection with the Bagan people on the island in the middle of the lake. If you find a similar sign, let me know as soon as possible. ”

After hanging up the phone, Cai Wenyue left his office, and the next place he was going to was the Dongtan International Conference Center.

Not long ago, when Chen Bin and the others came to the Criminal Investigation Bureau, some ideas put forward by Chen Ting gave Cai Wenyue new ideas, especially the inference that the murderer she mentioned was likely to lurk on the island in the middle of the lake and had a relationship with the people of Bagan, Cai Wenyue recognized it very much.

The island in the middle of the lake is not big, and it is all the property of the Bagan people, and it is not difficult for Cai Wenyue to check them, he just doesn't want to startle the snake for the time being. Because at this stage of the case, it no longer matters who the murderer is, the murder case has become a spy case, the more Cai Wen wants to investigate, the more he wants to check the upline behind this, the following chess pieces may not be able to run on the island in the middle of the lake, but before finding clues related to the behind-the-scenes line, digging out the chess pieces too early is bound to make the case difficult to complete.

When he arrived at the Dongtan International Conference Center, Cai Wenyue went straight to the security department inside and inquired about the recent situation of people and items entering and leaving.

"Nothing out of the ordinary?" What he learned was not unexpected, and Cai Wenyue didn't expect to gain anything in this point. He asked the person in charge of the security department to get a record of the recent entry and exit information, and found that the last time Li Guangping's laundry delivered clothes to the convention center was the day after the "Snow Dragon" left Hong Kong.

Cai Wenyue thought about it for a while, and felt that this was not a coincidence, he did not rush back, but went upstairs to the office of the "Yan Group".

Cai Wenyue was going to find Zhao Kang, and Zhao Kang was busy in his work room at the moment.

"Brother Wen Yue, why are you free?" Looking at Cai Wenyue, who knocked on the door and came in, Zhao Kang said with surprise on his face, although the two were in Dongtan, they had never had a chance to meet since they came back from the United States.

"Busy?" Cai Wenyue saw that Zhao Kang's desk was a little messy, and the pictures on several monitors on the desktop flickered non-stop.

"Help Brother Zhang make something," Zhao Kang took Cai Wenyue to the rest room and poured him another cup of coffee. "Brother Wen Yue, but what's the matter with me?"

"What's been happening outside lately?" Cai Wenyue nodded and asked straight to him.

"Outside? You mean the United States? Zhao Kang was stunned for a moment.

"There are other countries."

"Well...... everything is basically normal," Zhao Kang thought for a while, and suddenly added, "By the way, there is a Virginia-class attack nuclear submarine over there in the United States that suddenly left Norfolk Port a while ago, and its whereabouts are unknown." ”

"Oh!? What is the departure time? ”

Zhao Kang reported a time, and Cai Wenyue calculated that it was the day after the "Snow Dragon" left Chongming Island, and it was also shortly after Li Guangping's laundry sent clothes to the Dongtan International Conference Center.

"Coincidentally, hehe," Cai Wenyue sneered.

"What's the matter, Brother Wen Yue?" Zhao Kang asked.

"The espionage case is over," Cai Wenyue has already identified Li Guangping as the object of suspicion in his heart, and has also deduced that the departure of the Virginia-class nuclear submarine in the United States is related to the "Snow Dragon". "The news seems to have been sent from here."

"Here? Where? Zhao Kang has spent most of his energy lately cooperating with Zhang Dada to develop software to decipher alien scripts, and correspondingly pays less attention to what is happening around him.

"There are spies inside the Dongtan International Conference Center, and the news of the departure of the 'Snow Dragon' should have been sent to the United States from inside." Cai Wenyue said.

"What?! Are you saying that the nuclear submarine of the United States is heading for the 'Snow Dragon'? God, will Brother Zhang be in danger? After Zhao Kang reacted, he couldn't help but get anxious, "The people of the United States want to do something to our scientific research ship?" ”

"It shouldn't be possible," Cai Wenyue shook his head, "The whereabouts of the 'Snow Dragon' are unknown to outsiders, and it is not easy for the people of the United States to find its location, and even if they can find it, I think most of them are carrying out tracking tasks." ”

"That's good," Hearing Cai Wenyue say this, Zhao Kang put down his heart.

"Recently, pay more attention, it's not a good thing to have spies inside," Cai Wenyue reminded him, "You should pay attention to the security of your data, but also pay attention to your own security." I'm still investigating the homicide case in Xuandong, and I already have some eyebrows about the outside members of this spy, but I haven't done it for the time being because I'm afraid that it will startle the snake. ”

"Okay, I know, Brother Wen Yue, you should also pay more attention to safety." Zhao Kang nodded, and he had already decided to divide his energy into one part. Scientific research is important, but if the internal troubles are not eliminated, it is likely that your hard work will only make a wedding dress for others.

Cai Wenyue guessed correctly, the news of the departure of the "Snow Dragon" was indeed transmitted to the United States by the spies in the Dongtan International Conference Center. After Chen Jincheng received the information sent in by Gao Ningning, he immediately sent the information through his own unique channels, although he did not know the whereabouts and tasks of the "Snow Dragon" after its departure, but he knew that the movements of this big ship were very valuable for intelligence.

Warsanton attaches great importance to this information, because not long after the academic exchange conference held at the Houston Research Institute ended, they released some extraterrestrial scripts, and the Chinese side made new moves. According to the speculation of the people of the United States, they believe that Huaguo has some unknown information, which may be the key to the departure of the "Snow Dragon".

Once the matter involves the study of viruses or alien civilizations, it is the highest level of intelligence for all governments, and the United States authorities did not dare to slack off, they used half of the satellites that were still in operation to capture the movement of the "Snow Dragon", and dispatched a Virginia-class attack nuclear submarine, which is one of the few remaining nuclear submarines in the United States, which was previously deployed at Norfolk Naval Base as an important force to protect the "heart" of the United States.

Gao Ningning's method of sending the news was very ingenious, originally she was lurking in the east alone, although she obtained some data of scientific research projects from Yang Yudeng, but there was no hidden channel to send things to Chen Jincheng's hands. Now after the showdown with Park Jae-hyo, he got this Olympic aid, Park Jae-hyo is also very powerful, he spared no expense to win over Li Guangping, who opened a laundry in Dongdong, just to use his way to change clothes for the Dongtan International Conference Center.

According to Park Jae-hyo's request, Li Guangping sent some of the clothes washed for the people in the Dongtan International Conference Center to Huxin Island, and these clothes were classified according to the names of the personnel, and among the clothes sent to Park Jaehyo were Chen Jincheng's clothes.

Park Jae-hyo handed the clothes to Gao Ningning, who quietly embroidered the information in the form of Morse code on Chen Jincheng's clothes. This code was only an early form of digital communication, but unlike modern binary code, which uses only zeros and one or two states, Morse code consists of five types: dots, strokes, pauses between dots and strokes, medium pauses between each word, and long pauses between sentences.

Morse code has long been obsolete, but it is perfect for use here, because there are very few people who understand it and study it nowadays, and Gao Ningning embroiders these points and strokes that represent practical meaning with the same color thread in the inconspicuous position of the clothing, such as the position of the collar or cuffs.

The security department of the Dongtan International Conference Center focused on whether or not to carry things during the inspection, and no one would have thought that there were some small dots and gestures embroidered on the hidden places in those clothes, Gao Ningning embroidered these things on the clothes, she could be sure that Chen Jincheng could find them, because Chen Jincheng was a senior spy, and it was impossible for him to be unaware of the abnormalities in the collar and cuffs.

After Chen Jincheng obtained the information, he only used to remove the thread of the same color embroidered on the clothes, and the clothes were restored to the original state, and no one could find a trace from them. If Chen Jincheng wants to send a new instruction to Gao Ningning, he only needs to draw a scoop on a gourd and embroider the message on his clothes in the same way.

Gao Ningning's deception is not bad, but what she didn't expect was that her opponent was Cai Wenyue. Cai Wenyue is a person, but Hua Guo has been an undercover spy in the United States for many years, and he has been immersed in the Secret Service for a long time, and he is the person who works with Kelly, the Minister of Homeland Security of the United States. Cai Wenyue has come into contact with and dealt with countless espionage affairs, and the methods he has seen are also varied, Gao Ningning's methods may be able to hide most people, but when facing Cai Wenyue, as long as there is a clue in his eyes, all the conspiracies will soon be hidden.

Cai Wenyue's sense of smell is very sensitive and his movements are very fast, while Gao Ningning is still immersed in the joy of succeeding in his trick at the moment, and he is unaware of the gaze that is about to stare at him.
