Zheng Yilun's expression was a little stiff, but he asked politely, "Mr. Lin, what's your opinion?"

"Don't be in a hurry to punish her. Finding the killer is the key. Let me ask!" Lin Xiao walked up to Li Wan. Instead of frightening him, he asked politely, "Li Wan, you tell me what you know. Did you poison director Zhang?"

"No, it's not me, it's really not me!" As soon as Li Wan's eyes brightened, she seemed to see the hope of clearing the suspicion, and quickly climbed up to Lin Xiao, "I was wronged. After I went in, I saw the man in black killed director Zhang. He also laughed at me, and then ran into the rest room."

"You mean the killer laughed at you?" Lin Xiao was slightly stunned. The news was a little unusual. It proved that the killer had no intention to kill him. His eyes suddenly turned cold. "Why didn't you say that just now?"

"I, I dare not, dare not say..." Liwan said with a bitter smile. She was afraid of being suspected. How could the killer smile at her in that case? Are you stupid?

The more the truth is, the more incredible it will be. If Liwan had just talked to Zhong Kai for the first time, he would have been beaten to death.

"Nonsense Zhong Kai sneered, "killer killed people, but also to the witnesses smile, you think we are all fools?"

"Shut up Lin Xiao stares at him, the voice is not so domineering, but also very fierce.

Zhong Kai grinned and stepped back. He didn't dare to say a word. He looked at Zheng Yilun. He didn't have any expression on his face, and he couldn't say anything. He dropped his eyes slightly and stood still like a wooden man.

"Liwan! With me, you can say whatever you want. " Lin Xiao faintly feels that there is something wrong with it. Judging from Li Wan's performance, she doesn't seem to be an accomplice of a killer. If she is, her acting skills are excellent.

Zheng Yilun seems to be a little unhappy, but under the influence of Lin Xiao, he doesn't dare to refute anything. Even if his real identity is very important, he can only bear it now.

"Mr. Lin, I think the facts are very clear, right? The most urgent task is to find out the real murderer. If I'm afraid of being late, in case the murderer escapes -- "Zheng Yilun said with a stiff smile," isn't that good? "

"Haven't you blocked all the exits? If someone runs away, it's something wrong with your people, isn't it? " Lin Xiao said with a smile.

"Er --" Zheng Yilun felt his nose awkwardly, some speechless, so he spread out his hand at will, with a look at you.

Lin Xiao's eyes turn around. In front of Zheng Yilun, Li Wan is afraid to tell the truth, but even if Zheng Yilun is not at the scene, Li Wan may not dare to tell the truth.

It's not clear why Xiao Wan and Zheng WAN are really in conflict. The reason is not clear.

"Well, from the line of Liwan, check the murderer first." Lin Xiao immediately made a decision that finding the murderer first was the right thing to do.

"All right!" Zheng Yilun's eyes flashed and clapped.

Pop!

After nodding his head, Zhong Kai grabbed the walkie talkie and gave an order to all the security guards: "speed up the investigation, all the identity information should be investigated."

There are hundreds of borrowers, most of them are students. According to the location of the surveillance video, the progress is much faster, and most of them are ruled out.

Moreover, as the key target of investigation, the identity information of each person who has contacted with Liwan should be investigated clearly.

The dead corner of the library's cameras, as well as the guests from director Zhang's office who traveled around, were also closely guarded for the strictest scrutiny.

Everyone is waiting quietly, and the time is hard, especially Liwan, who is lying on the ground motionless, is in a state of panic at any time, because her fate is completely out of her control.

Lin Xiao's eyes had been wandering on Li Wan, and he didn't know what he was thinking.

In the quiet room, the atmosphere was a little strange. Perhaps in order to break this embarrassing situation, Zheng Yilun took the initiative to walk up to Lin Xiao, made a cup of tea for him with a smile, and asked, "Mr. Lin, you must have something important to do when you come to the library? I don't know if I can help

Lin Xiao quietly grabbed the cup, gently opened the tea, took a sip and said with a faint smile, "it's just looking up some classics. About the historical books of ancient times, does captain Zheng know where these books were stored?"

"Ancient books?" Zheng Yilun obviously didn't expect Lin Xiao to come to Zhennan library. His idea was to borrow ancient books, because few people usually borrow those books. Considering the words, he asked, "I don't know what part of history Mr. Lin is interested in?"

Lin Xiao didn't hide it either. He drew a light radian from the corner of his mouth and said, "it's said that in ancient times, there were many secret gates and martial arts were rampant. I'm very interested in the legends of the eight secret gates and the nine rivers in the yellow spring."

"Oh? It's true that heroes think alike. My interests and hobbies are too consistent with those of Mr. Lin. since I was a child, I've been fond of those masters who dance swords and guns. I'm very interested in their historical legends. When I grew up, I heard that Zhennan library has the largest collection of classics. So I managed to find such a position. I usually read books when I have nothing to do. I've really gained a lot of insight. " Zheng Yilun suddenly became interested and his face became colorful. He took the initiative to sit next to Lin Xiao and talk."The whole country of Xia! The history of Zhennan library is the oldest and the most profound. Almost all the historical books and records that can be found are kept. This is a huge treasure house. " Zheng Yilun took a long breath, and his eyes were more colorful. Speaking of this library, he seemed to have a lot of topics.

Lin Xiao was slightly moved and stunned. It seemed that the origin of Zhennan library was more wonderful than he thought. He could not help asking, "where are these books? Can I borrow it at ordinary times? "

"Ha ha - Mr. Lin, you don't know something. Some classics are very precious. Most people can't borrow them at all. Even some classics are never borrowed." Zheng Yilun knows Zhennan library like the back of his hand, and his bearing is not like a security team leader at all.

"Oh Lin Xiao nodded thoughtfully, "then I want to borrow the ancient books about Jiuhe in huangquan. What procedure should I do?"

"This --" Zheng Yilun was slightly stunned. He took a deep look at Lin Xiao, and suddenly sighed, "the ancient books of Jiuhe in huangquan are the most precious. Ordinary people can't borrow them easily."

Without waiting for Lin Xiao to speak, Zheng Yilun quickly added: "of course, Mr. Lin is not an ordinary person. However, the secret code of huangquan Jiuhe is in the hands of director Zhang. Now that he has an accident, he has to apply to the curator to reset the password. The curator is very hard to speak, and no one will face him. I'm afraid it will be very difficult to do this."

Zheng Yilun, with an expression of helplessness, showed his hand to Lin Xiaotan, smiling reluctantly.

"Who is the curator?" Lin Xiao asked again.

Zheng Yilun is about to speak.

"Captain!"

At this time, Zhong Kai suddenly rushed to report, and said in a deep voice: "cable, someone found the killer's black strong clothes and put them in the toilet trash can?"

"Oh?" Zheng Yilun quickly got up. His indifferent eyes flashed across the Jing Mang in an instant and went out directly. "Let's go, Mr. Lin. let's have a look together."

Lin Xiao and Li Yueyao looked at each other and got up to follow.
