Nangongjin's helicopter had been flying along the normal track before it disappeared, but on the way, it suddenly deviated from the channel, turned 90 degrees and went straight to the Haitian building.

After arriving near Haitian building, the signal disappeared.

The signal disappeared just one minute after Nangong Fuhu received the call.

That means that after Nangong Fuhu received the call, he asked Lao Zhang to turn around, and then for some reason, the signal disappeared in Haitian building.

"Haitian building!?"

Standing in front of the 40 story Haitian building, Lin Xiao found that the nearby surveillance video could only see the street, and the high altitude was a blind area.

The helicopter didn't have an accident and didn't arrive at the airport. It can't disappear for no reason. It must have landed at a certain place after the signal disappeared.

There are a row of shops opposite the building, selling groceries, medicine and several fast-food restaurants, but recently the restaurants and grocery stores have been closed, and only one drugstore is still open.

From the direction of the drugstore, you should be able to see what happened in the direction of Haitian building. If a helicopter passes by and in the dead of night, the engine sound is enough to attract people's attention.

Lin Xiao crossed the overpass and entered the drugstore.

The middle-aged saleswoman wearing a mask glanced at Lin Xiao and said faintly, "the mask is sold out."

"I'm not here to buy a mask." Lin Xiao said with a smile, "I want to inquire about something."

"What's up?" The clerk was a little nervous.

"About eight o'clock last night. Were you in the store?" Lin Xiao asked.

"More than eight?" The clerk recalled it and suddenly said impatiently, "it's closed early. What's going on recently? Who will come out in the middle of the night."

"Closed?" Lin Xiao frowned and looked inside. "Is there anyone living on the second floor?"

"The boss lives! What do you want to buy?" After the clerk was stunned, he looked very impatient. He was upset enough to go to work in such a sensitive period. He also ran to a guy who didn't buy but asked around.

Lin Xiao took out a hundred yuan bill and put it on the counter. He smiled and said, "call the boss for me."

Seeing the money, the clerk's eyes changed instantly. He quickly put it away and immediately changed his attitude. "You asked about the helicopter last night? Don't ask the boss. I saw it all."

"Oh? Did you see the helicopter?" Lin Xiao asked anxiously.

"Of course, last night when I was about to close the door to work, I heard a buzzing noise in the air, which made my scalp ache. As soon as I looked up, I saw a helicopter hovering in the air. I thought it was medical first aid, so I took a few more eyes. I thought there were serious patients again, but it wasn't."

"And then?"

"Then the helicopter stopped at the top floor of Haitian building. It was nothing at night, so I closed the door and walked home, staring at it all the time. After the helicopter stopped at the top of Haitian building, it didn't move."

"Are you sure the helicopter stopped on the roof of Haitian building?"

"Sure! No problem!"

Lin Xiao turned and left.

The clerk happily took out the money and flicked it with his finger, "it's too easy to get this extra piece, hehe..."

Haitian building is locked, the whole building is on vacation, and very few people walk quietly.

Lin Xiao quietly opened the door and took the elevator to the 40th floor. The 40 story corridor was quiet and terrible, which made Lin Xiao vigilant. He tried not to make footsteps and slowly approached the stairs on the balcony.

The fire door leading to the balcony is hidden, 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 the door open.

The sun came straight and made Lin Xiao's eyes narrow slightly. He carefully turned the corner and finally saw the helicopter parked on the roof platform.

"What happened?" Lin Xiao walked quickly. The helicopter was already empty.

According to Lin Xiao's observation and analysis, there was no sign of fighting in the helicopter. Nangong Jin should get off the plane by themselves and then take the initiative to leave.

"Strange, where have they gone?"

Lin Xiaochao glanced around and found nothing unusual.

The electronic components of GPS were destroyed by brute force.

The only exit is the door just entered.

After returning from the original road, Lin Xiao found the positions of the two cameras in the corridor, but found that the power supply was offline.

Lin Xiao came to the monitoring room. The two security guards were sleepy. In order to avoid trouble, he directly knocked them unconscious and personally transferred the monitoring on the top floor.

What's more surprising is that all the video backups before yesterday have disappeared and have been covered by today's new video. Lin Xiao is not sure whether this is an artificial intention or a systematic coincidence.

In short, all the surveillance videos are gone, and we can't see anything that happened in the building last night.

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

Vaguely, when I saw a stranger in front of me, the two security guards were a little nervous. One of them immediately grabbed the baton hanging around his waist.

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

Money is easy to do things. When Lin Xiao took out a stack of 100 yuan bills, the two security guards immediately smiled.

Fortunately, they just took a shift last night and have been working until now.

Unfortunately, they didn't find anything unusual at all, and even expressed extreme surprise at the landing of a helicopter on the roof.

"Helicopter?" The two were confused.

"When did it stop?"

"No notice."

Lin Xiao's face was black. "Really didn't you find anything unusual?"

"No," said one of the stronger guys. "These days, the company in the whole building is on holiday. There are no strangers in and out except the occasional personnel on duty."

"It's not my boast. There are nearly 1000 people in more than a dozen companies in this building. I don't say everyone knows them, but as long as I see them, I can be sure which company they are. Strangers can't escape my eyes."

"Why was yesterday's surveillance gone?"

"Yesterday?" The stronger security guard was reminded by a word and hurried to check the monitoring records, "what a coincidence, our monitoring video is covered once every two weeks, and it's just time today, so it's covered."

"What a coincidence?" Lin Xiao looked strange.

"Who are you looking for? The helicopter on the roof must be a big man? But I haven't heard that any boss in this building has a helicopter."

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

The two security guards were very confused.

Lin Xiao couldn't ask anything, so he turned and left, leaving them looking at each other.

"What a strange man!"

"Inexplicable!"

The clue suddenly broke.

At this time, Lin Xiao's mobile phone received a wechat.

Nangong Zongzhe's voice.

"The caller has found it. Do you want to go there together?"

"Where is it?" Lin Xiao's eyes brightened.
