Li Anping was a little flustered and almost extinguished the candle, but fortunately, he had been on the battlefield for a long time, and he was more or less mentally prepared, and quickly regained his composure.

He was not in a hurry to open the door and go out, no matter how good Cao Ruofei was, it was impossible for him to monitor the office at home, and now it was late at night, and there was no one in the office building except for the guards at the door.

He gently placed the candle in a safe place, then opened a filing cabinet containing a lot of yellowed papers.

He took it out and looked at it, but was disappointed that these documents were some documents that had not been destroyed during the Kuomintang rule. He opened the other filing cabinets, which were either empty or containing various obsolete documents.

An ominous feeling rose in Li Anping's heart, and he turned around sharply and pulled the door, which was locked. He tried it a few times with the master key, but the cylinder didn't respond, and he tugged the door a few more times, but it didn't move.

Now his back was instantly cold, and he was fooled! fell for the cunning "barber" Cao Ruofei! It seems that Cao Ruofei has already prepared the countermeasures for being secretly investigated, but if you look a little closer, you can see the problem with the bookshelf, and the outer lock is also the simplest lock, which can be pierced open with a wire.

Cao Ruofei deliberately left such a secret room for the people who were secretly investigating him, and as soon as they entered the door, they would be locked inside. All he had to do was walk into the office and see the bookshelves moved, knowing that someone had broken into the secret room.

"Despicable!" Li Anping scolded viciously, he slapped the door panel a few times, and the door panel made a few low sounds, indicating that the door panel was very thick.

Could this door be controlled by some mechanism, if there is a mechanism it must be in the secret room, he accidentally touched it when he came in.

He came in before the door closed, and it closed without touching anything, so the mechanism was probably on the ground where it was entered.

Li Anping raised the candle and bent down to observe the ground, the floor of the secret room was an ordinary cement floor, which was integrated instead of a brick floor, not like a mechanism.

Li Anping still didn't give up, he knocked on every inch of the ground near the door with his hand and didn't find anything abnormal. Then he searched and knocked on the wall near the door, but the result was still the same disappointment.

Are you going to be locked up inside? Li Anping tried again with the master key, and he felt that the key had been matched with the lock cylinder, but it couldn't be turned, as if something was stuck in the lock cylinder and couldn't be rotated.

It can be seen that the so-called mechanism does not exist, and Cao Ruofei has done something to lock or this door. To fix the lock cylinder, there must be something like a wire, iron rod and so on that plays the role of a latch.

Li Anping opened the first filing cabinet again, found a piece of hard and thin paper, stuffed the paper into the crack of the door below, and then slowly pulled the paper in parallel. The paper was blocked directly below the lock, Li Anping pulled out the paper, and slid up along the crack of the door, the vertical crack did not block anything, and there was something blocking the paper in the crack of the door directly above the lock. There is a latch-like thing on the top and bottom that holds the lock cylinder in place from the door panel.

Cao Ruofei designed that this door could not only let in and not let out, these two bolts are automatically stuck in the hole reserved by the lock cylinder after the door is closed, so there must be a hidden buckle that can pull out the bolt.

This clasp must be near the door frame, or even on the door panel. Li Anping carefully inspected the door panel and door frame by candlelight, as well as the wall next to the door. The walls had been looked at before, and there was nothing suspicious; There are no clues on the door panels and door frames.

Li Anping was so disappointed, even if he knew in advance that Cao Ruofei was not simple, he still fell in love with him.

He has been trapped in the secret room for a long time, the candle is about to go out, he can't get out again, Cao Ruofei came early tomorrow morning and saw that the bookshelf had been moved, and he must know what happened.

When the time comes, Cao Ruofei will bite him back, saying that he is a Kuomintang spy in vain trying to steal information; Cao Ruofei may also have starved him to death in the secret room as if nothing had happened......

The candlelight is getting weaker and weaker, and it floats erratically, and this short minute or two is probably the last time for Li Anping to escape.

He regained his energy and thought about countermeasures, his eyes constantly rolling and scanning the door panels and door frames.

Suddenly, he noticed a spot above the door panel that appeared to be much smoother than the surrounding wood, and slightly concave.

This seems to be rubbed out by someone who has often touched it, and the candlelight is almost extinguished, and Li Anping can only gamble on luck. He reached out and touched around the small groove, and there was nothing unusual, and he put his index finger in the small groove and pressed it down hard.

The two crisp sounds of "click" should be the sound of the bolt popping up, and Li Anping finally saw a glimmer of hope.

Although the candle had been extinguished, he struck a match to find the keyhole, inserted the master key again, adjusted it a few times, the key and the lock were closed, and with a slight twist, the lock opened.

He opened the door, and with a dodge he walked out of the chamber, and let out a long breath. It's finally out!

Several days have passed, and Li Anping no longer dares to rashly go to Cao Ruofei's office to look for clues.

Although he often saw Cao Ruofei, he did not have the slightest chance to investigate. It is inferred from the fact that Cao Ruofei set up the secret room mechanism that he did not place anything unfavorable to him in the office.

The only way to pull out the tail of this old fox is to get close to him! He either went to Cao Ruofei as a full-time secretary, or entered the first-line team that could deal with Cao Ruofei; Cao Ruofei has a full-time secretary, which doesn't work, so he can only apply to join the front line.

Li Anping found an opportunity to ask his colleagues in the department how to apply for job transfer, and his colleagues told him that the personnel department was responsible for the transfer and designation, that is, Li Tang's department. He took a moment to go to the personnel department, and Li Tang happened to be there.

Li Tang saw Li Anping coming to him, and greeted him with a smile, since she learned about Li Anping's past, her impression of Li Anping has changed greatly. The reason for the transformation may be out of sympathy, she sympathizes with Li Anping for the loss of all his relatives; Sympathize with Li Anping for being so handsome.

Of course, the most important reason is that she was moved by Li Anping's words, she has heard a lot of arguments about serving the party and New China, and she has read from Li Anping's eyes the sincerity and enthusiasm that others rarely have, or in other words, Li Anping said those words more like an old party member who came down from the front line.

How did she know that Li Anping was really a party member, just an underground party member whose identity could not be confirmed.

"Thank you so much for letting me pass the interview." Li Anping was able to become a public security officer, but it was more because Li Tang suddenly changed his opinion of himself, and he has not expressed his gratitude to Li Tang since he joined the company. Then he said with some embarrassment, "Are you free?" Let me ask you something? ”
