"Si Chen, quick, find clues from the surveillance in this building! Yunxi, you go and check with the security team again, to see if Xiao Xiao has gone out during this time, or if he has found anyone with suspicious deeds!"

Ling Hao thought about it for a while, then gave a decisive order, and then hurriedly went to the building to look for it.

At this time, it has been almost half an hour since the end of work, and the office building of Nuoda Shengya Group is quiet, and there is no one at all.

In contrast, Ling Hao was not surprised. Shengya Group has always adhered to the corporate philosophy of "overtime is a manifestation of incompetence", so it is normal for this situation to occur.

Ling Hao ran almost all the way, starting a frantic search from the floor where Xiao Xiao's office was located.

Rushing frantically to every corner, even every toilet, even pushing open every door check regardless of 3721.

In the entire corridor, only Ling Hao's hurried footsteps remained, and there were calls from time to time.

The heart has never been so messy.

It was as if the most precious thing had been lost, and the heart was suddenly emptied.

However, Ling Hao ran through all the floors, but found no trace of Xiao Xiao.

Jian Mei's eyebrows were already wrinkled, but he had to return to Xiao Xiao's office again.

Hong Sichen has used Xiao Xiao's office computer to directly hack into the security system of the entire Shengya Group and gain the highest control.

Then starting from the monitoring on the floor where Xiao Xiao's office is located, he quickly retrieved it.

By the time Ling Hao came in, he had already retrieved two-thirds of the way.

"How's it going?"

Ling Hao was indeed in a hurry.

For the first time in my life, I felt anxious, but I couldn't do anything about it.

"Boss, don't worry, this surveillance can only find that Sister Xiao Xiao also went down the stairs after Yunxi sent the customer downstairs, but there was no trace of her after that......"

Xiao Xiaoqian frowned, and kept calling up the surveillance videos in all corners and flipping through them, but found nothing.

"By the way, Sichen, can you locate the location where Xiao Xiao's mobile phone is turned off?"

A flash of inspiration flashed in Ling Hao's mind, and he asked busily.

I can't contact the phone when it's turned off, but as long as you find out where it's turned off, maybe you can find some clues.

"Yes, Boss, wait a minute!"

Xiao Xiao's eyes lit up when he heard Ling Hao say this.

After tinkering with the computer for a while, he suddenly said in surprise: "Strange, Sister Xiao Xiao's mobile phone is still in this building!"

"What? Still in this building?"

Ling Hao's face changed, and his voice trembled a little.

"That's right, even if the phone is turned off, I can retrieve the current location through the program!" Hong Sichen nodded, but then said disappointedly: "But this can only locate the mobile phone is currently in this building, as for which floor or corner it is, but there is nothing to be done, in the final analysis, the resolution is not enough ......."

Ling Hao sat down, his right hand subconsciously stroking the tip of his nose, but he was nervously tracing clues in his mind.

First, I met with the customer.

Then Yunxi sent the customer downstairs, but Xiao Xiao went out from the stairs.

After that, there was no trace.

The phone was turned off, but it was still in the building......

"How much is the difference between the time when the phone is turned off and the time when Xiao Xiao goes out of the stairs?"

A flash of inspiration flashed in Ling Hao's mind.

After a while, Hong Sichen stared at the screen and said, "The time when the mobile phone was turned off was two minutes after Sister Xiao Xiao went out of the stairs......"

"Two minutes, only two minutes?" Ling Hao raised his eyebrows.

"By the way, customer! Sichen, quickly bring up the video of the customers Xiao Xiao met with before!"

Ling Hao's eyes lit up, and he slapped the table heavily with his hand.

Hong Sichen, who was retrieving the surveillance video, was taken aback by Ling Hao, and glanced at Ling Hao, but he didn't say anything, but immediately started to retrieve the previous video according to what Ling Hao said.

At this moment, Yun Xi ran in panting, and said breathlessly: "Brother Ling, I went to ask the security guard, I haven't seen Sister Xiao Xiao go out for a while......"

"Boss, come and see!

Before Ling Hao could say anything, Hong Sichen shouted without looking back.

Ling Hao and Yun Xi hurriedly approached each other.

Hong Sichen pointed to the surveillance video at the gate and said: "You see, there are a total of five customers who came in, but only four went out through the gate!

"Then where did the rest of the people go?" Ling Hao subconsciously turned his head, looked at Yun Xi and asked, "Yun Xi, do you remember where the other person went at that time?"

"At that time...... By the way, there was a person who said that he had a friend who worked at Shengya Group, and he wanted to meet him, so he didn't take the elevator down together......!

Yunxi recalled for a moment and blurted out.

"This person also went out from the staircase where Sister Xiao Xiao went out later!"

Hong Sichen retrieved the surveillance video on this floor, pulled it forward in half, and found the customer who disappeared inexplicably.

"Go backwards, zoom in!"

Ling Hao's pupils relaxed slightly, and he calmly commanded.

Hong Sichen quickly called up the positive image of the customer and enlarged it on the screen.

An unfamiliar face.

"That's right, it's this man! He has a lot of freckles on his face, which makes people feel numb when they look at him, so I didn't even dare to look closely at his appearance at the time......"

Yunxi pointed to the man on the screen, confirming with certainty.

"Freckles, I was almost confused by this trick!" Ling Hao sneered and said, "Yunxi, do you know where the medical laboratory of the Shengya Group is?"

Ling Hao stared at the face on the screen for a long time, and suddenly opened his mouth to an irrelevant question.

"Ah, medical laboratory?" Yun Xi was stunned by Ling Hao's sudden question, but he immediately reacted, frowned and thought for a moment: "You should be talking about the pharmaceutical R&D laboratory of Shengya Group, right? The branch factory on the outskirts of the city is about thirty-five kilometers away from here!"

"Thirty-five kilometers?" Ling Haojian frowned slightly, his eyes narrowed for three points, he thought for a moment, and suddenly got up.

"Let's go down the stairs and have a look!"

Ling Hao said as he walked outside.

Hong Sichen and Yunxi glanced at each other and followed.

The location where the three of them are now is on the thirteenth floor of the office building of Shengya Group.

Ling Hao didn't take the elevator, but walked from the staircase where the customer and Xiao Xiao had entered one after another as shown on the video, and then climbed down layer by layer.

Every time he reached the first floor, Ling Hao had to stop and listen carefully to the movement.

And so on and so on until you get to the first floor.

The staircase is still going down.

"Yunxi, is there a basement under this building?"

Ling Hao looked at the dark staircase, turned around and asked Yunxi.

"Here's this...... It seems to be a utility room and a storeroom, and I haven't been down, but I've heard people mention it......"

Yunxi shook his head after all.

"The phone is still in this building, but there is no trace on all floors, so ......"

Ling Hao pondered for a moment, and said decisively: "Let's go, go down and have a look!"

Ling Hao suddenly had a strong feeling that Xiao Xiao should be down here!

I had only searched for it floor by floor through the normal staircase entrance, but I didn't notice that this emergency exit actually led to the basement.

Spiral down the stairs and take the twenty-second staircase to the basement.

It's empty, it's big.

The sound of Ling Hao's shoes stepping on the floor was scattered and reflected back, emitting a hollow echo.

All around, there are closed roller shutter doors.

"Xue Zi'an, come out! I know you're here, there's no need to hide!"

Ling Hao stood for a moment, and suddenly said aloud.

Yunxi and Hong Sichen's faces changed together.

The sound swayed back and forth, and the echo shook the eardrums with a dull pain.

But what shocked the two was not this echo, but the "Xue Zi'an" that Ling Hao said.

Xue Zi'an, vice president of Shengya Hospital, tied Xiao Xiao, president of Shengya Group, here? What trick is he doing?

Ling Hao shouted like this, and after a long time, there was silence all around, and there was no movement.

Ling Hao glanced at the surrounding situation, and his eyes locked on a roller shutter door with a slight gap leaking an inch at the bottom.

After making a gesture to Hong Sichen and Yunxi, Ling Hao walked slowly but firmly towards the rolling shutter door.
