Thanks to Li Anping, who knew in advance that Cao Ruofei was a "barber", and had fought with him many times openly and secretly, he already knew how cautious, cunning and suspicious Cao Ruofei was.

In the case that Cao Ruofei has begun to pay attention to him, he can still get the job he dreams of, Li Anping keeps admonishing himself to be calm, this is not like the director of the Municipal Public Security Bureau appreciating his subordinates who have never met, but an invisible net opened by Cao Ruofei, waiting for him to fall in.

Li Anping sorted out his work ideas for the first few days, he couldn't do nothing because he didn't know Cao Ruofei's purpose, and he couldn't go with other team members to investigate the spies with clues.

Cao Ruofei hid too deeply, even if Li Anping had seen Cao Ruofei and his downline connector with his own eyes, he couldn't mobilize any strength, and he didn't dare to say that the people in the moving game were monitoring Cao Ruofei together, and he was caught when he was connecting.

Take 10,000 steps back and say, Li Anping has not read the content on the note of Cao Ruofei's joint, if it is only written one or two code words, with Cao Ruofei's cunning, he can easily cover up the past with work.

He can even say that he is here to arrest spies, because the people who connect with him don't recognize Cao Ruofei at all.

Li Anping was wondering whether to investigate the "cicada" and "swan", so that Cao Ruofei was forced to launch an offensive against him, and once Cao Ruofei made a move, his fox tail would be exposed.

It's just that this is too risky, and Li Anping needs to understand Cao Ruofei's movements first.

To track Cao Ruofei, Li Anping needs to know whether he is being followed first.

For this reason, after dinner, Li Anping told Wang Yidao that he was just going out for a stroll, and then paid attention to the movements around him while walking. For several days, he was unaware that someone was following him.

One night, he even walked in the direction of the "Cicada's" residence, almost to the street where the "Cicada" was, and he did not notice that anyone was following him.

After making sure that he was not being followed, Li Anping began to follow Cao Ruofei at night and on Sundays.

The results of the tracking made Li Anping extremely depressed, Cao Ruofei couldn't be more normal in his spare time, there were occasional overtime, books and things, and visits to relatives and friends, but there was no spy-related activities.

Where did Li Anping know that Cao Ruofei's cleverness was here. After the previous investigation, Cao Ruofei was still not sure whether Li Anping and Zhu Ting were targeting him, or whether there were people he was completely unaware of were targeting him.

Once he left behind the identity of the Kuomintang senior spy "barber" and no longer engaged in spy activities, and only appeared as the deputy director of the Municipal Public Security Bureau, even if all his downlines were caught, they all confessed, and they could confess that only the "barber" was a spy, and there was no sign to point to Cao Ruofei as a person, and there was no evidence to prove that Cao Ruofei was a "barber".

There was no result, Li Anping still didn't give up, he didn't believe that Cao Ruofei could hold his tail without showing it.

The more fruitless he was, the more anxious he became, and he began to ignore Wang Yidao's opposition and threats, and stubbornly followed Cao Ruofei as if he had gone mad.

At this time, Li Anping remembered what he found in Chen Xiao:

1333817--1233

247654--32117

What does this mean, did Chen Xiao deliberately leave it to confuse others, or was it indeed a password that he accidentally or didn't have time to destroy?

This is Li Anping suddenly remembered that the master had simply handed him some ways to crack the password, of course, even if he knew the method of cracking the password, he also needed the mother's book.

This Chen Xiao teaches physics, so it is difficult for the mother book of the code to be sandwiched in a physics book or other textbooks about physics. Li Anping thought about it and still felt that it was impossible, so he thought about it again, could it be that his code master book was hidden in that bookstore, after all, this Chen Xiao went to the bookstore every week!

On Sunday, on the way to the bookstore, Li Anping saw Cao Ruofei walking in front, and he followed Cao Ruofei into the bookstore.

Could it be that this Cao Ruofei is also looking for a password scripture in the bookstore, Li Anping thought about it and felt that he would monitor it now.

Li Anping, who was hiding in the corner and pretending to read, looked at the person opposite Cao Ruofei and was immediately dumbfounded.

In front of Li Anping, Fu Yun, who had made him think about it day and night, and hidden it deep in his heart, appeared.

Li Anping stood stunned on the spot, he never dreamed that Fu Yun would appear in front of him again, and he would appear thousands of miles away from Kunming. Li Anping was about to run up to recognize Fu Yun, but when she saw her walking towards Cao Ruofei, she walked up to Cao Ruofei and chatted with him intimately. Fu Yun was dating Cao Ruofei, and Li Anping was stupid.

He only felt that the reality was too cruel, and life gave him great irony.

When he was most bored, God gave him a perfect Fu Yun; When he was about to enter the palace of marriage with Fu Yun, Fu Yun suddenly disappeared; When Fu Yun magically reappeared, she actually walked with his worst enemy.

Li Anping had an urge to rush up and kill Cao Ruofei now, of course, he came to his senses immediately, which was a stupid idea.

Cao Ruofei not only looked at his Li Anping's household registration file, but also asked him face to face. Li Anping's file is purely coincidental to record that he never left the province, not even the area under the jurisdiction of the provincial capital.

He couldn't recognize Fu Yun in front of Cao Ruofei, perhaps, he couldn't recognize Fu Yun at all.

What is the relationship between Fu Yun and Cao Ruofei? If he and Fu Yun recognize each other, and Fu Yun said that the two of them met in Kunming, it will make Cao Ruofei even more suspicious of himself.

There will definitely be a chance to recognize each other in the future, Li Anping walked away with an indescribable mood.

Fu Yun's unexpected appearance made Li Anping confused, and the impulse buried deep in his heart surged up for a while, and soon became contradictory again, could it be that Fu Yun suddenly left him for Cao Ruofei?

As soon as this thought arose, Li Anping's heart was like a needle prick, and the more he thought about it, the more he felt that it was possible. At the beginning, Cao Ruofei should not have arrived in Kunming in December, and it is likely that he had been lurking for a long time waiting for the assassination operation.

And before that, he had his eyes on Fu Yun's parents, who were underground parties, and it was even possible that he also used Fu Yun. Fu Yun's parents were taken away by the Kuomintang authorities and imprisoned in a detention center, and then killed because of their own rescue failure.

If Cao Ruofei is sure that Fu Yun's parents are underground parties, he will either ignore them or kill them directly with his style of acting.

However, Cao Ruofei has nothing to do with this, so how can he explain that he and Fu Yun appeared at the same time in this city that did not belong to them?
