After turning off the video, Zhao Yu already had a certain amount of experience points, and spent 6,000 points again, using hacker instructions to keep the video that was about to self-destruct.

However, the mystery left to him by the murderer made him frown and did not understand the point.

The killer said that he had left a hint for himself, but ...... This tip...... Where the hell is it?

Could it be that the clue he said should be provided by Li Bencheng to himself?

However, Li Bencheng and the two gangsters are all dead?

How can I find a clue here?

Or...... He left the clue in Room 11, somewhere? Or was it the people who were tied up?

No......

Probably not, right?

Zhao Yu pondered that the other party's original plan must have been to wait until he entered room 11, and then use remote control to set fire.

With the fire, everything is burned out, what clues are there?

So, the clues left by the murderer shouldn't be in Room 11, so ...... Where else could it be?

Wait a minute......

Suddenly, Zhao Yu finally thought of the most critical question, could it be...... The clues that the murderer refers to are not clues on the surface, but ......

Thinking of this, Zhao Yu stood at the door of room 11 again, looked at the various electronic instruments inside, and then thought of the point.

That's right!

The murderer took so much effort to lure himself here, and so much effort to set a trap to burn this place.

So...... Presumably what he wanted to burn was the real clue he left for himself, right?

In addition to calculating themselves, the enemy also wants to achieve some of their goals, as long as they know their purpose, maybe there will be a major breakthrough in the case!

But...... Zhao Yu looked at the strange instruments in room 11, and he had never seen them before.

In desperation, he had no choice but to use another stealth identification instrument to identify a large instrument located somewhere in the room.

As a result, the identification results showed that this is a microparticle reset combination device, and in addition to the professional scientific terms in the manual, there are a lot of chemical symbols, and after looking at it for a long time, I don't know what this thing is for?

But...... Regarding this issue, it is difficult for Zhao Yu, because Zhao Yu still has 8 witnesses in his hand!

Don't forget, there are 8 people tied up in this room!

These 8 people are wearing white coats, they must all be staff here, they can always know what is being studied here, right?

So, Zhao Yu untied them one by one, first took them out of danger, and then used the stealth detector to dismantle the high-power communication instrument, so as to ensure the safety of this place.

All of them were terrified, and as soon as they got out of danger, they fled in all directions and sought help.

Zhao Yu hurriedly stopped one of the old foreign men who had no hair on his head and wore gold-rimmed glasses and asked him about the situation.

"Uncle," Zhao Yu tried to ask in English, "I'm a policeman, let me ask you, what is studying in this room?"

"I didn't know anything, I was knocked unconscious when I was fine," who knows, although the old foreigner spoke English, but the donkey's lips were not the horse's mouth, "and then, he was tied up and couldn't move...... Oops, oops...... I have an urgency to urinate, and I have an urgent need to urinate ......."

Depend on!

Zhao Yu scolded in his heart, and asked again: "Hurry up, you quickly tell me, what products do you have here?"

"Otherwise, we'll all be in danger!"

"Ahh......h We are making communication equipment! I am the designer of the signal amplification link, and I ...... We are a communications company......

"I ...... I'm in a hurry, really urgent......"

After saying that, the old man couldn't hold it back, so he broke free from Zhao Yu desperately and went to find the toilet.

Soon, with the help of these rescued people, the security guards of the building, and some other staff members came to the scene one after another, and after seeing the corpses on the ground, the scene became more and more chaotic......

In desperation, Zhao Yu had no choice but to take out his mobile phone and call Xiao Hang and Li Pearl respectively.

Li Zhuzhu, who received the call, hurried over, and this was the previous scene......

"Yes, all the surveillance has been turned off," at this time, a police officer in charge of the investigation reported to another police officer next to Zhao Yu, "I just checked, and the entire firefighting equipment has also been vandalized!"

"It's so dangerous," the officer said fearfully, "those liquids are all highly concentrated flammables, and once they burn, not to mention the 25th floor, the entire building will have to burn into a big fireball, and I don't know how many people will die......!

"Hmm......" the officer said with a solemn expression, "So, the nature is more serious than we thought, and it can even be characterized as a terrorist attack?"

"Hmm......" The officer shook his head in embarrassment, "Is it a terrorist attack, but it's not up to us to have the final say, isn't the National Affairs Section here to lead?"

"Yes!" the officer nodded, "We really can't make decisions about this matter, but...... Just to be on the safe side, I'd better call our director first! Someone will come later, and you will report ......."

"Yes!" the officer saluted, and the officer picked up the phone to report to his leader.

"Hey," Zhao Yu hurriedly greeted the police officer in Korean, and then pointed to room 11 and asked, "Tell me, what the hell is going on here?"

"I just heard these terrorists say," Zhao Yu pointed to the corpse again, "they took something important from it, and it may have something to do with the next terrorist attack!"

"Asi, won't you?" the officer was instantly fooled, quickly wiped his sweat and said, "This is just a lab for a technology company......! Is there anything that could have anything to do with a terrorist attack?"

Gee......

Seeing the police officer's reaction, Zhao Yu already knew in his heart, it seems that they don't know what this room 11 is for!

If it were just an ordinary technological product, it would be impossible to attract so much attention from the enemy, and even set it on fire.

Seemingly...... Zhao Yu turned his head and looked for Li Pearl's figure, at present, I am afraid that only Li Pearl knows best what this company does!

Seeing the time pass little by little, Zhao Yu couldn't help but be anxious.

"Hey," the officer tried to ask, "this colleague, can you tell me what happened now......?" What the hell is going on?"

"Zhao Yu!" Who knows, as soon as the little police officer's voice fell, Xiao Hang's voice suddenly came from a distance, but seeing Xiao Hang hurrying over, he asked Zhao Yu in Chinese, "Are you okay?"

Zhao Yu hurriedly stood up, waved his hand and said, "It's okay, it's okay, let's get down to business first, what I want you to do, how did you find out?"

"Wouldn't it?" Finally, the police officer next to him was dumbfounded, looked at Zhao Yu with incredible eyes and said, "You...... Are you Chinese?"

"Zhao Yu," Xiao Hang came to Zhao Yu in a hurry, and desperately took out his mobile phone and said to Zhao Yu, "I just received data from the UK, the DNA sequence of the headless female corpse is more than 99.9% similar to Simonna!!
