When he returned to the second basement floor, Zheng Lanlan had already found the construction structure drawings of the No. 2 office building, and after Niu Zhiyuan studied it carefully, he breathed a sigh of relief, judging from the drawings, there were no other hidden channels such as sewers.

"But who is the inner ghost? How does he receive the enemy? After Niu Zhiyuan made some arrangements, he did not let go, but became more and more worried. In fact, if you don't find out the inner ghost, the biggest hidden danger will always exist.

After a little hesitation, Niu Zhiyuan told Zheng Lanlan about the existence of an inner ghost, who was taken aback and lost his voice: "What, there is a traitor, this is ...... Who could this be? ”

Niu Zhiyuan shook his head and said: "At present, I only know that there is a mole, but I don't know who it is." Otherwise, it wouldn't be so troublesome, just arrest the mole directly. Sister Lan, think about it, who is suspicious? ”

Zheng Lan frowned and thought for a while, shook her head and said, "Impossible!" I just thought about everyone, and I felt that everyone couldn't have an inner ghost. We have a total of 43 staff members, and the shortest ones have been here for more than a year, and all of them have undergone strict political examination. ”

When Niu Zhiyuan heard this, his brows furrowed tightly, he thought for a while, and said, "Sister Lan, you take me to your place of work for a turn, and let me meet with everyone." ”

Zheng Lanlan looked at the time and said, "There are still ten minutes to start, everyone will go to the canteen, let's go directly to the canteen, just while eating, while observing." ”

"Good!" Niu Zhiyuan immediately agreed.

The canteen is on the first floor, and when the two of them came to the canteen, people had already entered the canteen one after another, and Niu Zhiyuan found a place to sit down directly opposite the door, which could see everyone who entered the canteen clearly.

It's just that after eating a meal, Niu Zhiyuan looked at everyone who came to the canteen, although a few young men saw Zheng Lanlan constantly adding vegetables to Niu Zhiyuan, and looked at him with some jealousy, and even some hostility, but the more this happened, the less likely it was to be a traitor.

"Are there any people who didn't come to the dining hall to eat?" Niu Zhiyuan was a little unwilling.

"I just took a look, and I all came to eat today, and I didn't go out to eat." Zheng Lanlan handed over her mobile phone

Come over, forty-one names were typed on it, and it was obvious that she was also very attentive, and she did things carefully, and all the people in the future secretly wrote them down.

Niu Zhiyuan sighed, maybe his ability to observe his behavior was not enough, and the mole was hidden very deeply, and he couldn't see the problem.

After the two left the canteen, they walked all the way to the monitoring room, Niu Zhiyuan frowned and pondered all the way, remembering that in addition to the behavior observation method, he also had another content in the reconnaissance class of middle school in the past six months: personality analysis and elimination method, and suddenly said to Zheng Lanlan: "Sister Lan, I said two personalities, you can help me find it." ”

Zheng Lanlan was stunned for a moment, and without asking the reason, she said, "Okay, you say." ”

"The first type is a person who has a withdrawn personality, has no friends in the unit, and likes to be alone. The second is that the company is very popular, can get along with everyone, and enters everyone's work area without feeling anything wrong. ”

Zheng Lanlan thought for a while and said: "There are two people in the first type, one is a very old scientist, his name is Zhou Faqiang, because he is too stubborn and likes to argue with others, so he has no friends, everyone calls him old and stubborn. There is also a person named Chen Lele, who graduated from the Department of Computer Science of Kyoto University seven years ago and entered our unit to work, he is a computer master, he is a real withdrawn character, I heard that he is an orphan, usually silent, rarely participates in the gatherings of colleagues, and does not seem to have any friends. ”

Niu Zhiyuan's eyes flashed, and he said: "That old scientist named Zhou Faqiang can rule out, how old is this Chen Lele, is he married?" ”

Zheng Lanlan thought for a moment and said, "Chen Lele is thirty-three years old and has never heard of him getting married. ”

Niu Zhiyuan perked up and said, "Okay, this Chen Lele will be kept first, Sister Lan, think about it again, is there the second type of person I said?" ”

This time, Zheng Lanlan said without thinking: "You said that the popularity in the unit is very good, and he can get along with everyone, there is really one such person, his name is Bai Jinyang, the director of the office of our No. 2 research laboratory, 43 years old, has been in our unit for 20 years, I don't think he should be a traitor." ”

Niu Zhiyuan thought for a moment and said, "Listen to you."

said, the possibility that this Bai Jinyang is a traitor is very small. Well! But the one named Chen Lele needs to be investigated further. ”

Zheng Lanlan asked curiously, "How do you investigate?" ”

Niu Zhiyuan said confidently: "This is also going to trouble Sister Lan to take me to visit Chen Lele." ”

"Chen Lele lives in the dormitory of the unit, and he goes back directly to take a lunch break at noon, so we can visit now." Zheng Lanlan immediately got up and walked out.

"Okay!" Niu Zhiyuan agreed and followed.

The dormitory of Dajiang Science and Technology Biological Group is in the easternmost part, and the two of them walked through a garden and grove, Zheng Lanlan pointed to a six-story residential building and said: "Chen Lele lives in the room on the right hand on the fourth floor of the second unit, the one with the curtain drawn, let's go up!" ”

Niu Zhiyuan looked up and found that the curtains of Chen Lele's room were drawn very tightly, and he felt more and more that there was something wrong with this Chen Lele, after all, it was daylight, and the window railing was pulled tightly after eating, which was a bit abnormal.

Niu Zhiyuan asked Zheng Lanlan to go up and knock on the door, he held the pistol inserted under the coat on his waist in his right hand, and put his ear to the door to listen to the sound inside, after all, if the other party is really an internal ghost, it is likely to be a hidden master, it is better to be cautious.

"Who!" After Zheng Lanlan knocked on the door, an impatient voice came from inside.

"It's me, Zheng Lanlan." Zheng Lanlan was a little nervous by Niu Zhiyuan's actions.

"Wait a minute." Someone inside agreed, and then Niu Zhiyuan heard the sound of getting out of bed, putting on shoes, and walking.

A few seconds later, the door opened from the inside, and a man in his early thirties with messy hair and black-rimmed glasses, wearing a pair of pajamas, appeared in front of Niu Zhiyuan and Zheng Lanlan.

"Zheng Lanlan, do you have something to do?" Chen Lele frowned and glanced at Zheng Lanlan and Niu Zhiyuan, and said expressionlessly.

"Uh...... It's nothing, I just want to ask about the little software you did last time. Zheng Lanlan hurriedly thought of an excuse.

Chen Lele snorted coldly, glanced at Niu Zhiyuan, and said with a disdainful expression: "Zheng Lanlan, if you doubt me, you will doubt me, can you find a clever excuse." ”
