It took nearly 40 minutes for Lin Jiangbei to complete the sampling of 12 people.

At this time, Ye Luping also rushed back from outside and handed two bottles of gallic solution to Lin Jiangbei, "I was afraid that one bottle would not be enough, so I bought two bottles on my own initiative, and it was not expensive anyway!" ”

Lin Jiangbei nodded, the more he came into contact with Ye Luping, the more he could discover Ye Luping's advantages. No wonder he was able to follow Zhou Fengshan for five or six years, and there was really something!

"Brother Lu Ping, I have one more thing to trouble you." Lin Jiangbei said, "The sample test results will not come out until an hour, you now collect all the weapons of the twelve of them, and then lock them in a basement room in a group of two." After the test results come out, release the people who are not suspected! ”

Ye Luping turned his head to look at Zhou Fengshan, Zhou Fengshan waved his hand and said, "Just do what Jiangbei tells you to do!" ”

Ye Luping no longer hesitated, walked up and arched his hand at Chen Haitao, Gu Siqiang and others, and said, "Everyone, I'm sorry!" Let you suffer a little grievance for the time being. ”

Chen Haitao smiled bitterly, he didn't expect that he had just fired Xu Zhiji's gun before, and when he turned around, his gun was going to be dropped, which was really unpleasant!

He reached out and took out his matching gun from his waist, and even handed the pistol with Xu Zhiji to Ye Luping.

Seeing that Chen Haitao took the lead, the others naturally didn't dare to say anything, so they all took the initiative to take off the matching gun and handed it to Ye Luping. Then Ye Luping put them in groups of two and put them in a cell in the basement.

Seeing that Ye Luping walked back with the key, Lin Jiangbei said to Du Chenghu again: "Inspector General, the light in the basement is too dim, and you may not be able to see the reaction between the sample in the ampoule and the gallic solution. Your office on the second floor is brightly lit, and the students think it's better for us to go there! ”

"Okay, let's go!" Du Chenghu immediately agreed, and accompanied Lin Jiangbei to his office on the second floor with Zhou Fengshan.

Entering the office, Du Chenghu and Zhou Fengshan stared at Lin Jiangbei hopefully and began to test the samples with gallic solution. But he didn't want Lin Jiangbei to put the tray in his hand on the desk, rubbed his cheeks with his hands, and shouted: "Oh, I'm so tired from acting!" ”

Du Chenghu and Zhou Fengshan were shocked, and looked at Lin Jiangbei in disbelief: "Acting? What kind of play are you playing? ”

"Principal Zhou, Inspector General, I'm sorry." Lin Jiangbei said: "What the students did in front of them was acting. The so-called gallnut solution can detect oleander leaf powder, which is completely made up by students, and the gallnut solution will not turn pale green if it comes into contact with oleander powder. ”

Du Chenghu almost didn't squirt out a mouthful of old blood.

He pinned all his hopes on Lin Jiangbei, who knew that what Lin Jiangbei said before was actually made up nonsense? Wouldn't he be killed by Lin Jiangbeizi now?

However, Zhou Fengshan was calmer, knowing that since Lin Jiangbei had painstakingly performed such a scene, he must have his reasons, so he asked: "Jiangbei, what is your purpose in acting this scene?" ”

"Of course, it's to fish out the poisoning suspect!" Lin Jiangbei said, "However, the chief inspector asked me if I could quickly find out the poisoning suspect, and if the student replied that he said no, then I am afraid that all twelve people who were secretly tortured would be locked up for a long and tedious screening work." Not only is this a lot of work, but it also doesn't allow for time. So in a hurry, the students came up with such a way to see if they could fish out the suspect who was poisoned. ”

Although he understood what Lin Jiangbei meant, Du Chenghu still shook his head and said, "Jiangbei, I don't understand, how can this method fish out the poisoning suspect?" You yourself said that the gallnut solution will not react with oleander powder! ”

"Chenghu, don't be impatient, you listen to Jiangbei first!" Zhou Fengshan waved his hand to let Du Chenghu keep quiet, and then motioned for Lin Jiangbei to continue.

Lin Jiangbei looked up at Du Chenghu, "Chief Inspector, let's put aside the matter of gallic solution for the time being, and first go back to the matter of Wang Longfei being poisoned, logically reasoning, who is the most suspicious of poisoning." ”

"Well, you say!" Du Chenghu nodded.

"First of all, the person who poisoned him must recognize Wang Longfei and know his identity as a Japanese spy before attacking him." Lin Jiangbei said, "And Wang Longfei was carried into the underground torture room in a sack, that is to say, except for the four people in the underground torture room, no one else saw Wang Longfei's appearance, and they didn't know that Wang Longfei was in the sack, so they had no reason to take the initiative to poison him." ”

"That's true!" Du Chenghu pondered for a moment and agreed with Lin Jiangbei's statement, "The rules of the secret torture department are very strict, and when the torture is carried out in the torture room, unrelated personnel are forbidden to go over. And I hadn't heard anyone in the torture room mention anyone going to the torture room, so the others didn't know who was being interrogated in the torture room. ”

Speaking of this, Du Chenghu's eyes narrowed, "Jiangbei, do you think it's possible that someone has a problem with the four elite henchmen I sent to you to capture Wang Longfei?" Two of them came here with you, although they said that they left after handing over Wang Longfei to the torture room, but in the middle, there was still time to commit crimes. ”

"This possibility can basically be ruled out!" Lin Jiangbei knew that Du Chenghu was concerned about it, "Chief Inspector, they knew two days ago that we were going to arrest Wang Longfei, and they also helped me do a lot of secret investigation work. If any of them had a problem, they would definitely secretly notify Wang Longfei to escape in advance, so how could they do this and cooperate with me to arrest Wang Longfei back, and then find a way to poison Wang Longfei to death? ”

Hearing Lin Jiangbei say this, Du Chenghu secretly breathed a sigh of relief. You must know that those four henchmen are his elite team in Hangzhou, if something goes wrong with the four of them, then the blow to him will be even greater than the betrayal blow of the entire secret torture department.

"According to your analysis, the person who poisoned Wang Longfei is among the four people in the torture room?" Du Chenghu said.

"Yes!" Lin Jiangbei said, "Because Chen Haitao also knew two days ago that we were going to arrest Wang Longfei, so if he really has a problem, he won't wait until today to make a move." ”

"In that case, there's no need for you to act!" Du Chenghu slapped the table and said, "We directly arrested the four people in the torture room and interrogated them one by one, I don't believe that we can't find that Wang Balamb!" ”

"Chief Inspector," Lin Jiangbei shook his head and said, "We don't have that much time, and I can't guarantee whether this poisoning suspect has other accomplices in the secret torture department." So it's better to lure the snake out of the hole and let the poisoning suspect jump out by himself. ”

"What's the trick to lure a snake out of a hole?" Du Chenghu and Zhou Fengshan asked in unison.

"It's easy!" Lin Jiangbei reached out and took out a small box from his pocket, picked out a little from it with a cotton swab, added a little to the ampoules of the four members of the torture room and Chen Haitao, and then said with a smile, "Oh, that's it!" ”
