The helicopter that Nangong Jin was riding was flying on the normal trajectory before he disappeared, but suddenly deviated from the channel and made a 90-degree turn, heading straight to the direction of Haitian Building.

After arriving near Haitian Building, the signal disappeared.

The time when the signal disappeared was exactly one minute after Nangong Fuhu received the call.

That means that after receiving the call, Nangong Fuhu asked Lao Zhang to turn the direction, and for some reason, the signal disappeared in Haitian Building.

"Haitian Building!?"

Lin Xiao stood in front of the 40-story Haitian Building and found that the nearby surveillance video could only see the streets, and the sky was a blind spot.

The helicopter did not have an accident or arrived at the airport. It could not have disappeared for no reason. It must have landed at a certain location after the signal disappeared.

There is a row of shops across the building, including groceries, medicines, and several fast food restaurants, but recently, restaurants and grocery stores have been closed, and only one pharmacy is still open.

From the direction of the pharmacy, you should be able to see what happened in the direction of the Haitian Building.

If a helicopter passes by and when it is late at night, the sound of the engine is enough to attract people's attention.

Lin Xiao crossed the overpass and entered the pharmacy.

The middle-aged female clerk wearing a mask looked at Lin Xiao and said lightly, "The mask is sold out."

"I'm not here to buy masks."

Lin Xiao smiled and said, "I want to find out something."

"What's the matter?"

The clerk was a little nervous.

"At about eight o'clock last night, were you in the store?"

Lin Xiao asked.

“After eight o’clock?”

The clerk recalled and suddenly said impatiently, "It's closed early. Do you don't know what happened recently?

Who will come out in the middle of the night?"

"Close?"

Lin Xiao frowned and looked inside, "Is anyone living on the second floor?"

"The boss lives! What are you going to buy?"

After being stunned, the clerk seemed very impatient. He was already annoyed enough to go to work during this sensitive period, and a guy came to him who didn't buy anything but asked questions.

Lin Xiao took out a hundred-dollar bill and put it on the counter, and smiled, "Call me a boss."

Seeing the money, the clerk's eyes changed instantly. He quickly put them away and immediately changed his attitude, "Are you asking about the helicopter last night?"

No need to look for the boss, I'll see it all."

"oh?

Have you seen a helicopter?"

Lin Xiao asked anxiously.

"Of course, I was about to close the door and get off work last night when I heard a buzzing sound in the air, which made my scalp hurt.

As soon as I looked up, I saw a helicopter hovering in the air.

I thought it was medical emergency, so I took a few more glances. I thought there was another serious patient in some house, but it turned out not."

"What happened later?"

"Later, the helicopter stopped at the top of Haitian Building.

There was nothing to do at night, so I closed the door and walked home, staring at me, and the helicopter stopped at the roof of Haitian Building and stopped moving."

"Are you sure the helicopter stopped at the top of Haitian Building?"

"Confirm! No problem!"

Lin Xiao turned around and left.

The clerk happily took out the money and bounced it with his fingers, "This outer piece is too easy, hehe..." The door of the Haitian Building was locked, and the entire building was on vacation, and few people walked around quietly.

Lin Xiao quietly opened the door and took the elevator to the forty floor.

The forty-story corridor was quiet and terrifying, which made Lin Xiao become alert. He tried not to make footsteps and slowly approached the stairs that climbed the balcony.

The fire door leading to the balcony is closed, and you can even see the clear sky behind the fire door at a glance.

Lin Xiao walked up step by step and gently pushed open the door.

The sunlight pierced directly, causing Lin Xiao's eyes to narrow slightly. He carefully turned around the corner and finally saw the helicopter parked on the platform on the rooftop.

“What’s the situation?”

Lin Xiao walked over quickly, and the helicopter was already empty.

According to Lin Xiao's observation, there were no signs of fighting in the helicopter. Nangong Jin and the other two should have got off the plane by themselves and left on their own.

"Strange, where did they go?"

Lin Xiao glanced around the left and right, and found no abnormalities.

GPS's electronic components were destroyed by brute force.

The only exit is the door that just entered.

After returning from the same route, Lin Xiao found the locations of the two cameras in the corridor, but found that the power supply was in the offline state.

Lin Xiao came to the surveillance room. The two security guards were drowsy. In order to avoid trouble, he knocked the two out and personally retrieved the surveillance camera on the top floor.

What is even more surprising is that the backup of the videos before yesterday is gone and has been covered by today's new videos.

Lin Xiao was not sure whether it was artificial intentional or systematic coincidence.

Anyway, all the surveillance videos are gone and nothing happened in the building last night was not visible.

In desperation, Lin Xiao had to wake up the two security guards.

In a daze, when the two security guards were a little nervous when they saw a stranger appearing in front of them, one of them immediately went to grab the baton hanging around his waist.

"Don't be nervous! I just want to ask you something."

It is easy to do things with money. When Lin Xiao took out a stack of 100-dollar bills, the two security guards immediately smiled.

Fortunately, the two happened to take shifts last night and have been around until now.

Unfortunately, they found no abnormality at all, and even expressed extreme surprise that a helicopter was parked on the roof.

“Helicopter?”

The two were confused.

“When did you stop?”

"Not notice was received."

Lin Xiao's face turned dark, "Isn't it really noticed an abnormality?"

"No," said one of the stronger guys, "the whole building has been on holiday these days. Except for the occasional staff on duty, there are no strangers coming in and out."

"It's not that I'm bragging. There are nearly a thousand people in this building. I don't say that everyone knows them, but as long as you meet them, you will definitely be sure which company they belong.

A stranger will definitely not escape my eyes when he appears."

"Why did the surveillance camera disappear yesterday?"

"Yesterday?"

The slightly stronger security guard was reminded by a sentence and quickly checked the surveillance record. "It's a coincidence that our surveillance video is covered once every two weeks. Today is just the time, so it is covered."

"What a coincidence?"

Lin Xiao looked strange.

“Who are you looking for?

The helicopter on the roof must be a big shot, right?

But I haven't heard of any boss in this building that has a helicopter."

"Yes, I haven't heard of it."

The two security guards were very confused.

Seeing that nothing was found, Lin Xiao turned around and left, leaving the two of them looking at each other.

"This person is so weird!"

"baffling!"

The clue suddenly broke.

At this moment, Lin Xiao received a WeChat message on his mobile phone.

Nangong Zongzhe's voice.

"The person who called was found, should I go there together?"

“Where?”
