After Liu Yanzhang heard the sound, he did not stop him, while Zilong lowered his head and dialed the number.

A few seconds later, the phone was connected. Liu Yanzhang stood beside the crack in the door and looked back at the private room. However, no phone ringing sounds rang in the room, and everyone was still talking and laughing.

"Di Lingling!"

Almost at the same time, the phone ringing suddenly rang in the corridor, and Zilong suddenly looked up.

At the entrance of the stairs about thirty meters away, a man wearing a baseball cap entered the stairwell calmly.

"Chasing him!"

Zilong held the phone, shook his legs and chased after him, while Liu Yanzhang stood there after thinking for a few seconds, because he didn't want Jiang Guangnan and others to notice his abnormality, so he only adjusted his mindset and pushed the door and entered the private room with a smile.

A few seconds later, Zilong rushed into the stairwell and did not hear the phone ringing, but there were rapid footsteps coming downstairs.

"Chasing, chasing..." Zilong urged everyone, and dialed the number again with the phone, but the other party was already shut down.

"Oh shit!"

Zilong cursed, put the phone in his pocket, and then went downstairs and chased after him at a rapid pace.

Less than two minutes later, Zilong reached out and pushed open the door of the stairwell on the first floor, looked forward, and saw people rushing in the hotel lobby, and the man wearing a baseball cap arrived at the main entrance calmly.

"It's the one wearing a hat, chase him!" Zilong greeted his companion again, reached into his arms with his right hand, held the handle of the gun and chased after him.

Hotel entrance.

Zilong stood on the steps and glanced around, but he didn't see the man wearing a baseball cap. Then he turned his head and ordered: "Looking for the alley, he just came out, and it's impossible for him to cross the road!"

"good!"

"You two go over there!"

“…!”

Everyone responded, and they were about to look for the alleys on both sides of the hotel.

"Well!"

At this moment, a taxi started in front of the hotel door, and drove to the main road at a very fast speed. The window film of ordinary taxis was not too dark, so Zilong stood on the steps and could clearly see that the man in the baseball cap was holding a gun in his hand, forcing the taxi driver to leave the hotel.

"Brother Long, are you driving to chase after me?" The brother behind him immediately asked after seeing the taxi.

"When will you drive the car over? Everyone has left and I am still chasing the chicken feathers." Zilong frowned and replied, and immediately called Liu Yanzhang.

After more than ten seconds, the phone was connected.

"Hello?!"

"The person ran away from the main gate." Zilong went straight to the topic: "I didn't catch up."

"...Haha, come on, Guangnan, you're drinking less." Liu Yanzhang sat in the private room, greeting everyone, and asked with a smile, "What do you think?"

"Check the hotel surveillance immediately, but I don't have the power." Zilong responded after considering for a while: "You find an acquaintance from the Public Security Bureau and ask him to come to the hotel to adjust the surveillance in the name of investigating the case."

"Okay, okay, hehe, okay..."

"The other party wore a gray hoodie and a light blue denim duckball cap, which was very easy to identify!" Zilong reminded again.

"Okay, just do what you said. I'll go to the company to chat tomorrow." Liu Yanzhang replied and hung up his phone.

...

More than two hours later, Liu Yanzhang was still drinking with everyone in the private room, while Zilong met Guankou in the car downstairs.

After a few simple greetings, the relationship frowned and said, "It's just a little thing, I'll let me come here, so I can tell you how bad it is."

"Isn't this a hurry?" Zilong grinned: "The man in gray clothes has caused trouble in the company and is no longer showing up now. We can only ask for your help."

"Don't do this next time." After replies with annoyance, he turned around and explained to Zilong: "I can't copy his surveillance video because I don't bring the equipment... In this way, you go to their security room and go directly to them for me, and they will watch the video for you again."

"Hello, thank you!" Zilong thanked with his hands clasped his hands.

"Be kind to the point, if someone asks, you are the auxiliary police officer who helps the city bureau."

"I understand, understand!"

"Okay, then you go down!"

"Hello, please trouble you!" Zilong knew that the other party was annoyed by people like him, so he immediately pushed open the car door and walked down.

...

Twenty minutes later, Zilong only brought two people into the security room, mentioned the name of the relationship, and stood next to the computer and watched the surveillance video.

"I checked you. The man wearing a baseball cap had seven images in the hotel, but most of them were scenes of him entering, going into the elevator, and going out..." The security guard adjusted the surveillance video and whispered: "I watched it several times and felt that nothing was abnormal about this person...!"

"Have he been to any guest room? Have he met anyone?" Zilong bent down and asked again.

"No, he just walked around the third floor. Oh yes, I went to the toilet!" the security guard replied softly.

Zilong was stunned when he heard the sound: "Toilet? Please call out this video and I'll see!"

"good!"

After saying that, the security guard called out the scene of the man in the baseball cap going to the bathroom, but he kept lowering his head, so the surveillance camera never showed his face.

Zilong bent down and stared at the screen for more than two minutes. When he saw the man in the baseball cap coming in and out, he found nothing unusual.

"...Nothing is abnormal?" the security guard turned around and asked.

After thinking for a long time, Zilong suddenly pointed to the screen and said again: "Your father was touching out the picture after entering the toilet!"

"Then there is no picture of this person!"

"Don't look at him, just adjust it." Zilong waved his hand and urged.

After saying that, the security guard adjusted the scene ten minutes before the man in the baseball cap entered the toilet, and this time Zilong finally discovered a huge clue.

...

After more than ten minutes.

Zilong walked out of the hotel, lowered his head and dialed Liu Yanzhang's number with the phone.

"Hello?!"

"Is it easy for you to speak?" Zilong asked bluntly.

"I'm still having a meal, what's wrong?" Liu Yanzhang asked back.

"Then I say, listen!" Zilong responded concisely: "The boy we chased is the one who called you! Because you heard it too, as soon as I called the phone, his cell phone rang, and when we chased him, he ran out...!"

"Well, you keep talking!"

"I just came out of the surveillance room and found that this kid entered the bathroom on the third floor. At first, I didn't see anything, but I asked the security guard to transfer the scene ten minutes before he entered... I found... Jiang Guangnan also entered the toilet!" Zilong licked his lips and said, "But the private room where you eat is on the fourth floor. Why did he go to the toilet on the third floor if he has nothing to do? And not long after he entered, the person who called you also went in!"
