Criminal Investigation Chronicle

Zhao Lei and others inspected the six workshops, but found nothing. They went to the row of buildings behind the warehouse and entered the exhibition hall. The area of ​​the exhibition hall is very large, more than 200 square meters. There is one person hanging, it is Li Yong.Li Yong's hands were bound. One end of the rope was tied to a steel pipe on the roof, and the other end was tied to Li Yong's wrist. Li Yong was suspended vertically in the air at a height of more than two meters above the ground. The four-meter hole is about sixty centimeters deep, and the hole is filled with sharpened bamboos, densely packed.While everyone was observing the situation, the iron door of the exhibition hall was closed suddenly, and there was a sound of locking outside.

The loudspeaker in the exhibition hall sounded, and Zhao Feng's voice came: "Officer Zhao, the second level begins. Have you seen the steel pipe with the rope tied? There is fuel in the steel pipe, and now it is heating up. I have done experiments, and 150 A heavy object of 10 catties can be melted in 10 minutes under heating. These [-] minutes are the longest time left for you. Have you seen the gun on your left hand side? There is a bullet in it, which is provided for you Props. But in this factory, I have buried a lot of bombs. If you don’t follow my rules, I will detonate them immediately. The timer starts.”

Zhao Lei looked at his watch. It was 10:25 in the morning. According to Zhao Feng, the rope would blow at 10:45.But in the huge exhibition hall, it was tidied up, except for a few bundles of ropes, there was nothing else.Zhao Lei checked the gun, and it was exactly as Zhao Feng said, there was only one bullet.At this time, Zhao Lei noticed that heat could already be seen on the steel pipe tied with a rope, and he knew that what Zhao Feng said was true. Judging by his figure, Li Yong's weight was estimated to be around 150 jin, and the rope could hold it for 20 minutes at most. .

Lu Jiang called "Second Brother" a few times, but Li Yong didn't respond, probably in a coma.Zhao Lei first went to the edge of the hole and tried the bamboo below with his hands. I don't know what Zhao Feng used to fix it, it was so strong that he couldn't pull it out at all, and it was obviously impossible to destroy the dense array of bamboo sticks under Li Yong. Yes, at least hundreds of sharp bamboo sticks were inserted into the four-meter-by-four-meter hole.Looking at the time, at 10:28, Zhao Lei was anxious, but he didn't show it, but Lu Jiang looked anxious, wishing he could grow wings and fly up to his second brother.But in this exhibition hall, there is not even a table or stool that can be used as a foothold, and the four-meter-by-four-meter bamboo stick formation under Li Yong is even more insurmountable.

Zhao Lei took out a piece of paper and quickly calculated it. Based on Li Yong's height and his arms stretched by the rope, he estimated that it was two meters long. The length of the rope was about 1.2 meters. From where Li Yong was to the edge of the hole, there were two meters left. The distance, Li Yong's feet are about two meters away from the ground...

After more than a minute, Zhao Lei explained to Lu Jiang and Lin Chong with the full drawing. plan.

Zhao Lei took the rope and tied it, and distributed it to Lu Jiang and Lin Chong. Lu Jiang and Lin Chong stood on the left and right sides of the bamboo stick formation, facing each other. Then Lu Jiang threw the rope on the left side of the bamboo stick formation and hung it on Li Yong's ankle. , Lin Chong also threw the rope and hung it up. The two pulled the rope with their hands, made a gesture, and began to tighten the rope. In this way, Li Yong, Lin Chong and Lu Jiang formed a circle with Li Yong's ankle as the top. The angle of the isosceles triangle is about 90°. The rope connecting Li Yong's ankle in the hands of Lu Jiang and Lin Chong forms the two waists of the isosceles triangle. The angles of the two waists are about 45°.

Zhao Lei looked at the time, it was 10:37, and there were only 8 minutes left.Then he said: "Old Lu and Lin, let's start."

Following Zhao Lei's words, Lu Jiang and Lin Chong began to pull the rope in their hands. Li Yong pulled towards him until the rope stretched straight, then Lin Chong let go and Lu Jiang continued to pull. After several times of pulling like this, Li Yong was pulled by Lu Jiang and Lin Chong to form a bridge with the connection between the steel pipe and the rope as the center. The fulcrum is similar to a simple pendulum movement with the rope plus Li Yong's length as the arc length.

Zhao Lei stared at Li Yong, who was swinging regularly, and checked the time. There were still 5 minutes left, but at this time, the rope that had been swayed and rubbed obviously could not last for 20 minutes, and the connection between the rope and the steel pipe even showed signs of loosening.Knowing that he couldn't wait any longer, Zhao Lei yelled "Old Lu is ready", then picked up the pistol on the left, loaded it, took aim, fired, and hit the rope with one shot. Jiang also yelled, exerted strength with both hands, and suddenly pulled the rope in his hand. Lin Chong let go of his hand. Then, the rope was shot and snapped by Zhao Lei. Lu Jiang suddenly pulled Li Yong over, and the two fell on the ground at the same time. On the ground, at this time Li Yong's hands were stuck on the edge of the bamboo stick formation, and his hands were pierced, but his head was just out of the range of the bamboo stick formation...

Zhao Lei wiped the cold sweat off his head. Lin Chong also came over to check on Lu Jiang and Li Yong. Li Yong was breathing normally and must have been anesthetized. His hands were stabbed and dripping with blood. Lu Jiang fell to the ground and pointed at himself. The sudden exertion just now, coupled with the throw of Dong Guo in front, sprained his waist.Feeling embarrassed, Dong Guo took off his shirt, bandaged it up for Li Yong, and apologized to Lu Jiang. Lu Jiang waved his hand and said nothing.

A voice came from the loudspeaker, and it was Zhao Lei's old acquaintance again: "Officer Zhao, not bad, it seems that Zhao Feng is right, these little tricks really can't help you." The person who spoke, Zhao Lei still had some impression, was Zou Xiaolong, When he was 15 years old, he planned to kill two people. He was cruel and ruthless, and the city was very deep.

Then the door of the exhibition hall was opened, and Zou Xiaolong walked in clapping his hands, looked at Li Yong who was unconscious, and Lu Jiang who had a sprained waist, pointed at Zhao Lei, Lin Chong and Dong Guo, and said, "Officer Zhao, when you sent me to In prison, I have been in prison for ten years. The prison is really a big dye vat, but after I was in prison, I was not played with like Liu Changshan. I have always played with others. After I was in prison for a month, two old men in our prison fought , resulting in one death and one serious injury, do you know what happened, those two idiots, I only used some verbal hints to fight. But after I was released from prison, I was not idle. Do you remember Hu Li? That woman killed Your wife is gone, do you want her?" Zhao Lei's hands trembled, and Lin Chong hurriedly took Zhao Lei's hands, and said in a low voice, "Brother Zhao, don't fall for it." He handed Zhao Lei another cigarette and lit it. After that, Zhao Lei's mood gradually stabilized.

Zou Xiaolong smiled again: "Officer Zhao, now one of your two helpers is unconscious and the other is injured in the waist. What, are you going to fight me?"

Zhao Lei took a deep puff of cigarette, stood up, and before he could speak, Lin Chong pressed Zhao Lei's shoulder and said, "Brother Zhao, I'll come." Lin Chong was five years younger than Zhao Lei, and his skills were better than Zhao Lei's.

Zou Xiaolong spat and said, "Why, Professor Lin also wants to do some activities?"

Lin Chong didn't talk nonsense with him, and kicked Zou Xiaolong with a whip kick.Zou Xiaolong didn't fight back, he took a few steps back and waved his hands and said, "Just kidding, I'm not Liu Chang'an, rough work like hands and feet is not my specialty, I surrender, you just tie me up, Anyway, there are still four levels, if you can’t pass the level and die at which level, someone will let me go.” Saying this, Zou Xiaolong crouched on the ground with his hands in his hands, and pointed to the rope on the ground, motioning for Lin Chong to come over and tie me up. he.Lin Chong came over and tied Zou Xiaolong tightly, searched him, and slashed the back of Zou Xiaolong's neck with a knife again, and Zou Xiaolong also passed out.After taking Zou Xiaolong and Liu Changan to the storeroom and tying them up individually, Zhao Lei and the others sat on the ground and rested. The continuous battle of wits exhausted everyone's physical strength.
