Yu Fei searched layer by layer. When he reached the entrance of the corridor, he stopped and listened carefully to know if there was anyone on this floor. When he let go of his sense of hearing, he could even hear the sound of breathing.

arrive.

In this way, he searched all the way to the top floor, but it was completely unfinished to go up any higher. He stopped and knew that this building was not the target he was looking for.

After going downstairs, Yu Fei took his disguise and came to the second target. Yu Fei thought that the other party would choose the two unfinished buildings that had been abandoned for a long time, but he did not expect to find anything.

After checking that it was getting late, Yu Fei went out to call Xu Bo and learned that after Liu Chuanzhi picked up Qin Xiaohua, they were walking to the city because they had to check to determine whether Lei Pei's bone marrow matched Qin Xiaohua.

, although the probability is high, it is not 100%.

Yu Fei was relieved that he still had plenty of time, and then he and Zhu Cheng came to the last location. The building here had stopped construction not long ago, and the surrounding grass had not grown up. There were not many pedestrians around, and there was not much garbage, so it was not very

It's easy to sneak in. You are a scavenger. There is no clean hair here. If the other party is observing upstairs and you suddenly approach, this will be obvious.

But Yu Fei knew that the two men committed the crime impromptuly, so his thinking was definitely not that comprehensive. If the other person was in this building, Yu Fei analyzed it first. According to his perspective, they were in the house on the south, so he went from the north.

Or the chances of being discovered are smaller when approaching from the east and west directions.

But after thinking about it again, the other party should try their best to stay by Xu Bo's parents' side to prevent them from escaping, or if the police came to the door, they would have the lives of the hostages ready to threaten them.

Therefore, Yu Fei felt that for the father and son, one staring at the south and the other staring at the north would be the most likely choice. There were few windows on the east and west sides, and many of them were corridor windows.

After Yu Fei finished his analysis, he still didn't rush in. Instead, he started observing downstairs. Soon he found that at the edge of a window on the south side, half a head would occasionally appear looking outside, and then he quickly took it back.

He observed the other three directions for about half an hour, but found no sign of observation by the other party.

Yu Fei was finally satisfied and asked Zhu Cheng to continue observing from the outside. From the east side with the fewest windows, he climbed over the iron wall with a scavenger bag, then raised his head and stared at the window above, and quickly walked downstairs, so that he basically arrived

The opponent's observation is blind.

There is a window opening more than two meters above the head, but no frame or anything is installed.

Yu Fei jumped up from where he was, grabbed the edge of the window sill and rolled in.

After arriving at the building, Yu Fei quickly found someone's footprints in the dusty corridor, or several people. There was too little dust, so the footprints were very unclear. He only knew that someone had walked by in a short period of time.

Yu Fei checked himself to make sure there was nothing on him that could easily make noise, and then he started to go upstairs carefully.

When Yu Fei walked to the fourth floor, he listened carefully and heard the sound coming from the construction site in the distance. His eyes suddenly lit up. It was similar to the sound in the call recording. It gave a sense of distance.

Yu Fei walked more carefully, and when he finally walked out of the corridor on the sixth floor, he suddenly stopped because he heard voices.

"You still want to drink water? Do you want to drink the urine? I'll be fine if I don't kill you. There are still a lot to ask for!"

A arrogant and arrogant voice was cursing people. Yu Fei heard this voice very familiar. It was definitely Lei Pei's half-brother. Because of the recording of the call between the other party and Xu Bo, Yu Fei listened to it in order to find out useful information.

I have memorized it many times. Everyone’s timbre has its own characteristics, and it is difficult for ordinary people to change it.

"Young man, it's okay if we don't give you water. Please untie us and let us go to the toilet! It's been almost a day and a night, and I really can't hold it in any longer!"

Xu Bo's father spoke. This voice was familiar to Yu Fei, because Yu Fei had gone to treat his illness twice, and there were some conversations in between.

"If you can't hold it in any longer, pull your pants down! You are the hostages now, it's good to be alive!"

Lei Pei's half-brother still showed no humanity at all. He even said on the phone that he would ensure the safety and health of Xu Bo's parents, but what he did was not humane at all!

"Young man, we don't want to run, and we can't run away even if you don't! If it doesn't work, you can just let my wife go to the toilet. She is a woman after all! Please, please?"

Xu Bo's father's plea came. After all, we are all human beings brought up in a civilized society. This request of Lei Pei, the half-brother, was simply not something that a human being could say.

boom!

"ah!"

Immediately afterwards, Yu Fei heard the sound of fists hitting people, and the screams of Xu Bo's father came out.

"Why are you talking so much nonsense! If you continue to talk nonsense, I will throw you off the stairs!"

Then the curses from Lei Pei, the younger brother, came out.

Xu Bo's parents were frightened and did not dare to speak out anymore. This guy was so violent and it was useless to reason with him, especially after he had the absolute right to speak, it was as if he had lost his humanity.

.

Yu Fei couldn't stand hearing this anymore. He heard such things when he first came here. Before he came, he didn't know what happened to Xu Bo's parents!

Yu Fei quietly walked out of the corridor. The corridor was designed with four households on one staircase, and there were four households in total. However, now it was just a cement frame, and not even a door was installed. There was nothing inside, and there was almost nothing from the door.

You can clearly see the situation in many locations inside.

Yu Fei left very carefully to prevent the other party from discovering him in advance, which would be detrimental to Xu Bo's parents.

When he came to the second door, Yu Fei stopped because he was sure that the sound came from this door.

Yu Feimai had the urge to peek out and observe, because the other party was a father and son. If he couldn't subdue both of them at once, one of them would have the opportunity to violently attack Xu Bo's parents.

But Yu Fei was prepared in advance. He had read so many suspense books and logical reasoning books on solving crimes in vain. He picked up a small piece of broken mirror outside.

Yu Fei squatted on the ground and carefully moved the small mirror he brought out from the ground. Human eyes are very capable of capturing fast-moving targets, but if small items move slowly,

It's not that easy to spot unless you're staring.

So when the small lens stretched out a little bit, Yu Fei observed the situation inside the room through the reflection.

The door can directly look into the living room inside. Xu Bo's parents had their hands tied from behind and were squatting under the wall of the living room. Both of them looked in pain. Xu Bo's father had scratches on his arms and face.

, he was also gritting his teeth in pain at this moment, his eyes were blue and purple, and it seemed that this was the area that had just been beaten.

Xu Bo's mother was facing Yu Fei from the side. She didn't seem to be in much better condition. She was shaking slightly. Yu Fei probably wanted to go to the toilet and was trying hard to hold it in. He had reached his limit.

As for Lei Pei's half-brother, he was holding a sharp fruit knife and standing next to him with a fierce look on his face.

There was another person Yu Fei didn't notice, who was naturally Qin Xiaohua's husband. However, he made sure that this guy was not around Xu Bo's parents. As long as he rushed in, he subdued Lei Pei's younger brother and saved Xu Bo's parents.

, then it won’t help if the other party comes out of other rooms.

Yu Fei tried his best to turn the lens to observe, but still couldn't find any trace of the other party.

Yu Fei slowly retracted the lens bit by bit, turned around and backed away slowly, and went to the other side of the house, to the symmetrical room in the house. Because it was a symmetrical location, the layout of the room should be exactly the same. It became familiar after going in.

After a circle, Yu Fei's mind formed a rough outline of another apartment.

Then Yu Fei planned to take action. As long as he controlled Lei Pei's half-brother immediately, then today's rescue operation would be considered a complete success. No matter which room the other person was in, he could easily take it down.

Then Yu Fei carefully moved back step by step. The ground was very rough, just a layer of cement, so you had to be very careful when walking, otherwise it would be extremely easy to make noise. They were the only people in this building, so it was actually very

A little quiet movement could alert the enemy in advance. With such a violent mood, if someone found out that someone was coming to rescue Xu Bo's parents, they would most likely commit murder as soon as possible!

When Yu Fei just arrived at the door of the suite and planned to take another look before taking action, he suddenly heard footsteps coming from a bedroom. The last person turned out to be in one of the bedrooms. He had probably been there just now.

Rest, it’s time to step out.

Yu Fei held his breath and concentrated, it would be easier to handle once he knew the location of the last person, but he didn't expect that the other person would come straight to the door.

"I'm going out to find a way to buy some food and water!"

Mr. Qin Xiaohua's husband's voice rang out, and he ran straight to the door as soon as he spoke. The sound of footsteps was very obvious, and the soles of his feet stepped on the uneven concrete floor, making a loud squeaking sound.

If the other party didn't come out so impatiently and gave Yu Fei enough time, Yu Fei could retreat and hide, and wait for this guy to go out before going in to deal with Qin Xiaohua's son. But now that the other party came out while talking, Yu Fei thought

It's too late to hide, and the movement made by moving too fast will be discovered.

So at this time, Yu Fei decisively decided to appear immediately. The further away the opponent was from the door, it would be most appropriate for him to rush in first and strike first. In this way, he would be closest to Qin Xiaohua's son. He could kill Qin Xiaohua's husband in an instant.

It only takes a second or two to reach Qin Xiaohua's son.

The reaction speed of ordinary people is limited, so the success rate of doing this is very high. The faster you take action, the shorter the reaction time of the other party.

When he understood this truth and knew that he had no choice but to take action in advance, Yu Fei hesitated for at least a millisecond. The next moment, he kicked the soles of his feet hard on the ground, and rushed out of the place with all his strength.

He rushed to the door of the room.

Yu Fei's appearance was so sudden that neither father nor son noticed it. So when Yu Fei rushed in, Qin Xiaohua's husband saw Yu Fei and only had time to make a horrified expression, while Qin Xiaohua's son,

The side is still facing this way, so the movement of turning the head has not yet been completed.

At this moment, Yu Fei exploded with all his strength and speed. Seeing Qin Xiaohua's husband, Yu Fei suddenly drew his right hand to his chest and pulled back his arm to gather strength.

Qin Xiaohua's husband didn't have time to react. Yu Fei was in front of him. When the two of them seemed to collide, Yu Fei had already finished accumulating his strength. He thrust forward with his right arm and hit him with his elbow.

chest.

boom!

The other party felt as if his chest had been hit by a sledgehammer, and he flew backwards. All the air he breathed in his chest seemed to be shaken out, which made it difficult for him to make any sound.
Chapter completed!
