Wu Tongguang and the two of them are about to solve the case, but according to Xu Bohao, if they solve the case, they will leave, and in this way, Mr. Bao will also suffer. Therefore, when Wu Tongguang asked Mr. Bao to notify the other four people to come over, he instinctively realized the crisis.

Mr. Security finally couldn't hold it back: "Instead of waiting for Captain Xu to come over, I'll catch them first!" He didn't know where to find a spear, walked to the door of the lounge, and raised the gun tremblingly.

Weapons can hurt people, but such weapons are obviously not very deterrent in the hands of such a security gentleman.

Li Wutong was at a loss for the second monk, Wu Tongguang had already walked over, and he still kept smiling: "Sir, don't be nervous, the murderer is not you." ”

"Don't come here!"

"What's wrong? I suggest you put down your gun right away. Wu Tongguang said in a commanding tone.

"Stop acting, you two aren't from the Garrison Command at all." Mr. Guard shouted hysterically.

Wu and Li glanced at each other: "It seems that it has been pierced." ”

Wu Tongguang continued to pretend and said fiercely: "You have to think clearly, what are the consequences of pointing a gun at me like this?" ”

Mr. Guard, as if greatly frightened, let out a shout, a "snap", and the spear went off.

The bullet hit the ceiling, and although it didn't hit Wu and Li, it would definitely attract more security and even the police station.

Wu Tongguang was not surprised, and said, "It seems that someone called you, right?" ”

Mr. Security said in a trembling voice: "Captain Xu said, if I don't hold you back, my whole family will die, you are not allowed to move, just stand in this place, Captain Xu will be there soon!" ”

Li Wutong said: "This Xu Bohao, threatens the whole family at every turn, this kind of person is too hateful, I have to punch seventeen or eighteen bullet holes on him the next time I meet." ”

Wu Tongguang couldn't bear it, and comforted him: "Don't worry, we won't leave until the truth is all figured out." Since we are against Xu Bohao, you should know who we are? ”

"You ...... Are you from the Communist Army? ”

Wu and Li didn't answer, and they acquiesced.

Wu Tongguang said: "We are good people. ”

Mr. Bao said: "I can see that you are good people, but I can't help but listen to Xu Bohao's words, this Nanjing city is still the world of the Kuomintang." ”

Li Wutong said: "Soon it won't be!" ”

Mr. Bao said excitedly: "I don't care, anyway, don't bother me at this moment." ”

Wu Tongguang said: "If you guard the door like this, we won't be able to leave, you can rest assured." Why don't we talk about Professor Zhu's case? ”

Mr. Bao said, "What is there to talk about? Don't you already know who the murderer is? ”

"I already know who the killer is, but I'm still a little unsure. Did someone ask you to take us to the third floor lounge? ”

"Yes, I called the academic office, and someone in the academic office said it."

"Well, I have one last question to ask, walking from the academic affairs room on the first floor to the lounge on the third floor, Secretary Wang Nianru said that he needed 2 minutes, what do you think?"

Mr. Bao thought for a moment and said, "I'm afraid it will really take so long." ”

Li Wutong said: "I understand what you want to confirm, 'that person' didn't return to the academic office on the first floor at all, so what he said about 'no time to commit crimes' is nonsense!" ”

Wu Tongguang said slowly: "Only 'that person' can deliberately ask Mr. Security to take us to the third floor, and 'that person' is the secretary Wang Nianru!" ”

Mr. Bao said: "It's him, he asked me to take you to the lounge on the third floor, saying that Professor Zhu will be there after class!" ”

"Secretary Wang Nianru."

The whole situation was like this, Wang Nianru was ready to kill Professor Zhu quietly, choosing to use the heart-urging needle as a tool, he deliberately informed Professor Zhu that there was a visitor on the second floor, and asked Professor Zhu to hurry down, and then he did not follow back to the academic office on the first floor.

According to the three students, they didn't see him again, so we thought that after he saw Professor Zhu, he went back to the teaching office, and it took 2 minutes to walk from the teaching office to the lounge on the third floor. ”

"However, the crux of the problem is that if everyone didn't see him in the corridor, it doesn't mean that he went downstairs to the lounge, and when Professor Zhu walked to the second floor, he not only went downstairs, but ran to the top of the building, using gravity and lead needles to stab Professor Zhu."

After Professor Zhu was poisoned, he took medicine in time to suppress the abnormal heartbeat, and because he couldn't rest assured of what he was hiding, he insisted on going to the third floor to check, and the doors and windows were naturally closed by Professor Zhu at that time. And at this time, Wang Ruru rushed down, and he was about to collide with us, so he hibernated, waiting for us to call him, he came slowly, not from downstairs to up at all, he was from the top of the building, turned the staircase and pretended to panic, and ran towards us, his statement that he did not have the time to commit the crime is indeed a lie. That is, at first he thought that the diary was in the lounge on the second floor, and now he had no chance to rummage through the real collection, and the diary must still be here. ”

Li Wutong finally heard what Wu Tongguang said, and couldn't help clapping his hands and said, "Wonderful!" ”

Wu Tongguang didn't seem to be proud, he was thinking about another question: since the diary that Professor Zhu hid was in the lounge on the third floor, where did he hide it? He had observed the use of this lounge where things could be hidden, except for the beam above his head.

Mr. Bao said: "This is all your personal inference, Secretary Wang will come up immediately, and he will confront you after he comes." ”

Wu Tongguang said: "Well, and what is the function of this hemp rope in Professor Zhu's hand, I haven't figured it out yet." ”

Li Wutong said: "Aren't you afraid that Wang Nianru will run away?" ”

"No, I just asked Mr. Bao to inform them, saying that I found a diary and asked the four of them to help take a look, so since Wang Nianru didn't succeed, how could he leave?"

As he spoke, he looked at Mr. Guard, who nodded, as if to indicate that the four had been notified as he had ordered.

"Nonsense!" Wang Nianru's voice sounded. Footsteps sounded in the corridor, naturally Wang Nianru, Xu Zhihan, Bai Wenyu, and Situ Wenwen came.

"What is this for?"

"Guard, what are you doing with your gun?" Several students looked at the room in amazement.

Mr. Bao took a deep breath and said, "Since you're here, then don't go, let's wait for Captain Xu to come." He retreated to the door, and with the barrel of the gun, he drove several students and Wang Nianru into the room.

Suddenly, as if he had noticed something, he picked up his gun and took aim......
