Leng Xuan went all the way up the stairs, listening to all directions and looking around. Fortunately, there were no surveillance cameras installed in this stairwell, and through his keen hearing, he found that the first and second floors were empty, without any sound. When he reached the third floor, he suddenly heard the sound of the door, so he quickly retreated a few steps and pressed his body tightly against the wall to avoid being seen.

   With his super ears, Leng Xuan could hear the footsteps of only one person at the entrance of the corridor on the third floor. Then, there was the crisp sound of a lighter. At the same time, there are electronic sounds of mobile phone keys. After talking nonsense with the person on the phone for a long time, he estimated that he had finished smoking, so he hung up and walked out of the corridor.

  Leng Xuan waited for a while, and when no one came out again, he began to walk up cautiously. When he reached the entrance of the corridor on the third floor, he opened the door of the safe passage to a gap and cast his eyes in. Leng Xuan saw that there was actually a hall made of transparent glass inside. In the center of the hall, there is a raised circular stage with several steel pipes standing on it. At this time, two coquettish women are performing striptease. Around the stage, surrounded by a lot of audience, one by one stretched out their hands, trying to grab a handful of ********'s plump body. There are also a few holding thick banknotes in their hands, shaking them from time to time, apparently wanting to use this in exchange for the other party's service for one night.

   Maybe the transparent glass has a good sound insulation effect, so Leng Xuan could not hear any sound. Shaking his head secretly, he turned his eyes elsewhere. At this time, a few people happened to enter the hall. They found a seat and sat in a group, and then waved to call the waiter. I don't know what to say, the waiter went away. And it didn't take long for the waiter to bring a plate over and put the things on the plate on the table.

  Leng Xuan's eyesight was good, and he quickly recognized that those things were ******, marijuana, and a smoking tube. He was immediately shocked. He did not expect that drugs are still sold here, and they are still sold in this way of ordering. It is estimated that there must be a lot of types and quantities of drugs stored here.

  Leng Xuan watched the process of openly buying and selling drugs, and couldn't help smacking his tongue. For this one crime alone, Li Cheng would have been shot several times at least. And it's only the third floor, there are two more floors above, I don't know what kind of dirty business they don't know.

   Looking back, Leng Xuan walked upstairs again. But this time, he was not so lucky. The security work on the fourth floor is obviously much stricter. Even outside the safe passage, there are special personnel to guard it. And the bulging waist is obviously equipped with a pistol.

  Leng Xuan suddenly had a headache. The security guard was standing on the only way to the stairs. No matter what method he used, he would be discovered by the other party. After pondering for a moment, his heart sank. Anyway, it's already here, and it's absolutely impossible for him to back down. In this case, the only way to solve the problem is to use force.

   He was calm, and when the security guard turned his eyes away, his body moved suddenly, like lightning, and rushed towards the security guard, his hand was like a sharp knife, and he slashed the security guard's neck fiercely. Immediately, the security guard's eyes darkened and his body fell backward. Leng Xuan quickly caught his body to avoid making noise when he fell to the ground, and then carefully dragged him to a slightly hidden place.
