"Is this a letter of challenge to me, or is it a letter of intimidation to intimidate me?"

This sudden mobile phone message has clearly indicated that Night Feather has been targeted by the detective killer.

"However, the killer has been arrested and imprisoned."

This is already a well-known incident of the armed investigators.

"So, the person who sent me this threatening letter is a copycat?"

Night Feather was actually more inclined to this guess.

Because when the killer became famous, Night Feather asked Rebinis to investigate all the information about this detective killer, and found that he was just an ordinary criminal who was not very powerful, so Night Feather asked Rebinis to send all the information of this detective killer to the police station, and arrested the killer who had not yet developed on the spot.

However, this copycat is a very clever criminal, and it is rumored that if this detective hitman targets a target, he will come to the vehicle that the target is going to ride in advance and plant a bomb, and then use a two-wheeled mechanical vehicle equipped with a submachine gun to remotely control the machine, constantly forcing the other party to continue to accelerate.

So, in this way, there will be two scenarios for the fate of the target person.

One is that when the vehicle is slowing down while constantly accelerating, it is killed by a bomb.

The second is to be shot with a submachine gun by a mechanical vehicle following behind.

This is a set of techniques that detectives have always used.

If the attack from yesterday evening was carried out by the detective killer who sent me the threatening letter, then there is a 90% chance that the detective killer was a copycat.

At least, from the information that Night Feather had, he hadn't heard of a case where a Detective Killer would train wolves to attack targets.

Thinking of this, Night Feather summoned Rebinis hidden in his mind and asked, "How is it, have you found this sender's network IP address?" ”

"When the other party sent the message, he used a virtual machine from the United States, and it was impossible to find out where the terminal of the virtual machine was where he operated the virtual machine." Rebinis's calm and crisp female voice sounded in Nightfeather's head.

"Yes, then cancel the search of him, and you can continue to work on your business, after all, this is a huge project, and you can't let this affect the progress of this plan."

"Yes! Master. ”

With that, Rebinis's voice disappeared from Nightfeather's mind.

"Well, anyway, I've been completely targeted by him, so I guess this mastermind behind the scenes will soon appear on his own."

"Fortunately, Bai Xue is going to stay overnight, otherwise it would be a bit of trouble to involve her as well."

In this way, Ye Yu has no worries around him at this time, and he no longer has to worry about the pond fish when he catches the criminal.

However, what was about to happen next ruthlessly shattered Night Feather's delusions.

"Bell Bell Bell ——!"

A rapid mobile phone rang suddenly, and Ye Yu just wanted to withdraw the phone into his trouser pocket, and his hand suddenly stopped in place.

The mobile phone call displayed on the interface of the mobile phone is Lou Lan, the instructor of the Assault Section.

"Why did she call me?"

Night Feather frowned, and an uneasy thought welled up from the bottom of her heart, so she pressed the answer button.

As soon as she received the call, Loulan's somewhat heroic tone became very serious at this time.

"You go to the top of the Assault Training Building now!"
