Staying in the room peacefully, Cheng Yu turned the notification sound of his mobile phone to the maximum, lay on the bed, and closed his eyes to recuperate.

Shortly after five o'clock, Cheng Yu's mobile phone made a dingdong notification tone, and he glanced at his phone and knew that it was caused by someone touching the infrared ray.

When Cheng Yu changed rooms, he mentioned to the waiter that he wanted to change to a room closer to the elevator room, which was Cheng Yu's room, which was simply arranged diagonally opposite the elevator room, and Cheng Yu only needed to open the door a crack, and the situation in the elevator room could be described as unobstructed.

Turning over and getting up from the bed, Cheng Yu walked behind the door, opened the door, and then stretched out the metal locking loop behind the door, just enough to jam the crack of the door, so that the door would not be completely closed.

Cheng Yu stood behind the door, adjusted the phone to camera mode, and then stuck the camera in the crack of the door, facing the elevator room.

Although it is impossible to see the situation of all six elevators, more than eighty percent of the space in the elevator room is within the scope of Cheng Yu's monitoring, and Cheng Fu will never be in the blind spot of Cheng Yu's vision as long as he appears.

At least, a part of Cheng Fu's body can also be seen.

Soon, Cheng Yu saw a figure appear in the elevator room, it was Cheng Fu.

Cheng Fu pressed the elevator and waited for about a minute, the elevator arrived as promised, and he stepped in.

Cheng Yu wanted to go out with him and take another elevator downstairs, but suddenly realized that something seemed wrong.

The picture of Cheng Fu stepping into the elevator just now flashed in his mind, especially the right leg he stepped out of first......

Cheng Yu suddenly reacted, where did he feel that something was wrong in his mind.

Although Cheng Fu was neatly dressed, he was wearing hotel slippers on his feet.

This kind of paper slippers are now allowed in many hotels, even when you go to a restaurant, you will be politely asked to go back and change into normal shoes.

Generally, they will wear paper slippers downstairs, either downstairs to pick up takeout, or to pick up friends.

Since Cheng Fu is wearing this pair of hotel paper slippers on his feet, this almost means that he does not plan to go out, and he will definitely return in a while.

So, Cheng Yu continued to monitor with the camera function of his mobile phone behind the door, and a few minutes later, he heard a crisp jingle when the elevator arrived, and then, he saw a white man with a height of 1.9 meters walking out of the elevator.

Subsequently, Cheng Fu also walked out behind him.

Since the white strong man didn't know which direction Cheng Fu's room was, after he stepped out of the elevator, he waited in place for a while, and almost subconsciously observed the surrounding situation.

And his actions also completely exposed his face in front of Cheng Yu's eyes, and was photographed by Cheng Yu's mobile phone.

Cheng Yu knew that this strong man, nine out of nine, was the killer from Irkutsk, Russia.

After Cheng Fu walked out of the elevator, he waved at the man, and the strong man adjusted his direction and disappeared into the elevator room after Cheng Fu.

Cheng Yu closed the door and stopped recording on his mobile phone.

Soon, there were two consecutive notification tones on his mobile phone, which indicated that Cheng Fu and the strong man entered the room one after the other, which would cause the infrared ray to be interrupted twice.

Cheng Yu knew that at this time, what Cheng Fu and the strong man said in the house must be very important, and it was likely to be related to their next actions.

However, Cheng Yu is not a real agent after all, it is not easy for him to do this, and even get the true appearance of the killer.

Even if it is a real agent, it is not so easy to install eavesdropping and even camera equipment in Cheng Fu's room just after opening the room, which requires the cooperation of the hotel.

And Cheng Yu is absolutely impossible to seek the cooperation of the hotel.

He could only wait patiently, and Cheng Yu felt that he should adjust the target of his tracking and instead stare at the Russian.

After tidying up his clothes in front of the dressing mirror, Cheng Yu deliberately lowered the baseball cap, and then walked out of the room.

From the other direction, Cheng Yu walked towards Cheng Fu's room in a long way.

went around a big circle, and in front of him was the 2807 where Cheng Fu lived, Cheng Yu lowered the baseball cap slightly again, then took out the room card and shook it in his hand, and when he walked to the door of 2807, he pretended to slip his hand and dropped the room card in front of the door of 2807.

Next, Cheng Yu naturally bent down and squatted to pick up the room card, and after picking it up, he also raised his hand and took off the infrared emitter that was originally glued to the upper left corner of Cheng Fu's room without a trace.

The whole process only lasted more than a second, and except for the one who raised his hand, the other behaviors seemed quite normal.

And the reason why this is necessary is because Cheng Yu has left a little more care, he is worried that the Russian killer who has just entered the room, out of the instinct of a professional killer, will check the settings in the room and observe the outside behind the cat's eye.

In this process, Cheng Yu avoided his face as much as possible from the range of the cat's eye, if someone behind the door was really observing, he would at most pick up the room card for Cheng Yu, and suddenly waved his hand when he stood up, feeling a little strange, but because Cheng Yu's body was very close to the cat's eye at that time, the person behind the cat's eye may not be able to see clearly that his left hand has such an action.

All in all, Cheng Yu avoided being discovered as much as possible, and took down the infrared device.

The reason why he wanted to remove it was because Cheng Yu didn't want to leave any traces, he didn't expect Cheng Fu to invite this Russian to the hotel room, and with Cheng Fu's ability and habits, it was difficult for him to observe the movement on the door frame.

But not necessarily the killer.

When he entered the door, maybe he wouldn't observe carefully because of Cheng Fu's relationship, but it was difficult to say when he went out.

Especially since Cheng Yu has decided to give up Cheng Fu's side and choose to track the Russian killer, then it is redundant for this infrared emitting device to continue to stay on the door frame.

After getting the infrared emitting device, Cheng Yu made a gesture of putting the room card in his pocket, and then walked quickly to the elevator room, turned his back to the direction of Cheng Fu's room, and pressed the elevator.

When he walked into the elevator, Cheng Yu also stepped in, and only turned around until the elevator door closed behind him.

The reason why this is so is also to ensure that even if someone opens the door to observe Cheng Yu when he passes by, it is impossible to see Cheng Yu's face.

After going downstairs, Cheng Yu went straight to the parking lot, and changed the clothes on his body with the original clothes in the car, and then he returned to the lobby and sat in the lobby.

This is a position where the elevator hall and the door can be clearly observed, Cheng Yu ordered a glass of sparkling water, picked up the fashion magazine prepared for the guests in the lobby bar, blocked his face, and pretended to read it.

Just ten minutes later, Cheng Yu saw the white strong man walking out of the elevator room.

In fact, this guy is not very suitable for the profession of killer, because his figure is too conspicuous, if he can't kill with one hit, or if the person who is killed has the support of his companions, then the process of running after the work will be more difficult.

Like this white man's figure, he would look special in any country, unless he was thrown into a bunch of models or volleyball players or something.

Because he saw that there was no figure of Cheng Fu behind the white strong man, Cheng Yu also put down the magazine in his hand, and Shi Shiran stood up.

Anyway, it was impossible for that white strong man to know him, so Cheng Yu was not afraid to meet him directly.

Before the white man, Cheng Yu walked out of the door of the hotel, and when he turned and walked towards the parking lot, he observed the white strong man with his peripheral vision, and he found that the target of the strong man should also be the parking lot.

Cheng Yu got into the Mercedes-Benz he rented directly, but he didn't rush to light the fire, but took out his mobile phone, lowered his head as if he was seriously replying to a message, or inquiring about something.

His eyes were slightly raised, and Cheng Yu saw that the white strong man was walking towards his Mercedes.

When Cheng Yu came to change clothes just now, he had already adjusted the position of the Mercedes-Benz.

Because he had confirmed the Honda Accord that Fu drove before, Cheng Yu parked the Mercedes-Benz in more than a dozen parking spaces in front of the Honda Accord.

Unless the white man came in another car, if he or Cheng Fu planned to drive away the Honda Accord, they would inevitably pass by Cheng Yu's car.

The white man looked around as he walked, looking cautious.

Seeing Cheng Yu in the car, the white man's footsteps paused slightly, and it was obvious that he was observing what Cheng Yu was doing.

Seeing that Cheng Yu was just lowering his head and concentrating on the mobile phone, the white man shrugged his shoulders, probably thinking in his heart that he was another modern person who was captured by the mobile phone.

He then walked over to the Honda Accord.

The reason why Cheng Yu thought that this white man would also use this Honda Accord was because he felt that this car should be that white man, after all, Cheng Fu had just arrived, how could he have prepared a car a long time ago.

But that's not the case.

No, Cheng Yu is lucky, but it can be regarded as a mistake.

This white man also arrived in Harbin today, and this is his first time in China, so the matter of transportation is not in his consideration.

And Cheng Fu's car was arranged by him a long time ago. If Cheng Yu had not left the parking lot of the airport before him, but left after his car, Cheng Yu would have found that when Cheng Fu left the parking lot of the airport, the parking fee for his car was as high as more than 5,000 yuan.

Because, Cheng Fu's car has been parked at Harbin's Taiping Airport for more than 140 days.

This is a second-hand car he bought when he last came to Harbin, and it has been parked at Taiping Airport since then, and the key is also deliberately hidden there.

After meeting with the white man, Cheng Fu handed over the car keys to the white man, which facilitated the white man's movements.

Anyway, the white man got into the Honda Accord and drove the car out of the parking lot.

Cheng Yu also slowly followed after the Honda Accord drove out, anyway, it was impossible for the white man to recognize him for the time being.

Following behind the Honda Accord, Cheng Yu carefully controlled the distance between the cars, but after driving two kilometers, Cheng Yu found that the driving speed of the Honda Accord seemed to become a little hesitant.

Cheng Yu knew that this was because his car had been seen by the white man before, and what Cheng Fu didn't realize didn't mean that the white man didn't realize it.

He's a killer after all.
