The other party obviously entered this office building, but now, it disappeared without a trace as if the world had evaporated.

That guy had a fight with Lu Yuan on the second floor, and if they wanted to leave the second floor, they had to go through the staircase. However, if the other party dragged the road far through the staircase, it would inevitably be discovered by me, and it contradicted the results of the investigation.

Since there was no trace of Lu Yuan anywhere near the second floor, it proved that he must have been taken away from there. The only explanation for this is that in addition to the stairwell, the other party has other means to take him out of the second floor.

Looking at the dark corridor, in an instant, I already had a conclusion in my heart.

Hold on to the flashlight and walk in the direction of the elevator.

Because the office building has been cut off from power, the elevator cannot function properly. However, apart from the staircase, only the elevator remains, which connects the various floors.

Just like the outside, the entire outside of the elevator door panel is also rusty, and it looks like no one has used it for a long time. However, I just raised my hand and gently cracked it, and the entire elevator door cracked a crack.

I leaned against the doors on either side, bit my flashlight, and burrowed into the dark patio.

Surprisingly, I didn't see an elevator in the patio, nor a cable as it should be, but instead a row of scaffolding, made of countless steel materials, appeared directly in front of me.

Quite different from the old elevator doors on the outside, the entire scaffolding is completely brand new, and it looks like it was built not long ago.

At this moment, I am almost certain that the secret hidden in this office building must be hidden in this elevator shaft.

Taking a deep breath and going all the way down the scaffolding, it is surprising that the inclination of each layer of steel frame is just right, even if it is a vertical climb, it hardly takes too much effort.

I don't know exactly how long I crawled in the dark patio. The dark space is like another world, which not only erases time, but also makes people forget their own existence.

Anyway, when I reacted again, there was a passage on the wall in front of me that was just right enough for a person to stand upright in and out.

Like the scaffolding on the upper floor, the passage was built a short time ago, and the cement lining of the two sides of the passage is out of place with the old exterior of the office building.

More importantly, I found a few drops of dark red blood at the entrance to the passage.

The blood penetrated into the cement, and in this darkness, there was an indescribable sense of weirdness. Could this be a trail of blood? Could it be that the mysterious man brought him all the way here after attacking Lu Yuan on the second floor?

Judging from the height, the passage in front of you is definitely one floor below, perhaps connecting to the basement of an office building. In this way, the tips Tang Yirou gave me at that time can be explained.

The group of bastards of the Yu Group are indeed hiding underground, and they don't know what they are doing secretly, at least, Tang Yirou and their eyes into the group should have conveyed such information to them.

What worries me is that with Lu Yuan's ability, under such circumstances, it is hard to imagine that he would be brought in from the second floor so easily without making any resistance. The only explanation for this is that at that time, Lu Yuan was no longer able to resist at all.

At this moment, I can't help but have a question in my heart, who is the mysterious person who took away Lu Yuan?

Looking at the dark pathway, I subconsciously swallowed my saliva, and then slowly moved towards the darkness. The path stretched forward, and after a few twists and turns in between, I walked through it for a while before finally coming to an end.

At the end of the passageway, a half-hidden roller shutter appeared. Surprisingly, underneath the roller shutter door, there was the light of an incandescent lamp. Could it be that the end of this passage and the office building do not belong to the same power supply system? After making sure that there was no roller shutter, I gradually lowered myself and carefully walked through the roller shutter.

In an instant, a dazzling white light came from all directions, enveloping my whole body, because I had been in the dark for a long time, and I was suddenly exposed to the strong light, and I felt that I couldn't open my eyes for a while.

After a moment's pause, my eyes were finally able to adjust to the light on either side. There wasn't much else around me during this time, otherwise I would have been easily subdued by those guys.

The space behind the roller shutter was bigger than I could have imagined.

I have to say that the place I am in now is like a well-renovated office hall. Smooth tiles, bright lighting, and a variety of facilities that are close to modernity.

To my left and right, there were countless passages that stretched in all directions. The walls of each passage entrance are briefly marked with signs.

On the wall directly in front of you, two eye-catching large characters are printed in bright red font, "Area A".

The moment he saw those two big words, he only felt a burst of electricity pass through his mind, and for a moment, the whole person couldn't help but tremble. The floodgates of memory slowly opened, and images of the past flashed before my eyes like a slideshow.

I've seen the same font in the abandoned underground research institute at House 37. And Ye Xianguo told me clearly at the time that the underground research institute was completely funded and built by Yu Yinghao.

Although I have only had formal contact with him once, I have also gained insight into some of Yu Yinghao's characteristics.

That guy is a rigorous, conservative person at heart. It is not difficult to see from the same suit and leather shoes of all the employees of Yu's Group. Such a person, once he gets used to something, basically will not change it.

For example, I am used to building my own research institute underground, and I like to mark the various areas of the research institute with two bright red letters such as the two bright red letters in front of me.

I'm in the underground research institute of Fuqiang Culture Company, and there is a faint smell of paint in the air around me. Judging from the information currently available, this research institute should not be more than three months away from completion.

Now that I have penetrated deep into the enemy's interior, I must be extremely cautious in every step I take, otherwise, not only me, but even Lu Yuan may lose my life.

I wanted to take out my mobile phone and inform Xu Fugui of the situation here, so that he could dispatch people to help as soon as possible. Compared with Tang Yirou's "verbal agreement", no matter how you look at it, it is still more reliable on the police side.

However, looking at the display of no signal on the mobile phone screen, my heart suddenly cooled by half. In order to prevent insiders from leaking information, the other party must have placed a signal shielding device somewhere in this underground research.

In this way, it can also explain clearly why Tang Yirou and they infiltrated the inner line of the Yu Group and could not deliver accurate information.

Without outside help, everything that follows can only be done on your own. It's just that after the previous tragic encounters, it's easier to accept this.

The first step is to be the first to rescue Lu Yuan, with his help, it will be easier to deal with things later.

However, after entering the underground research institute, Lu Yuan's bloodstains disappeared completely, and I didn't know where to find his whereabouts in the face of the countless paths around me. When I was confused, there was a slight sound in the passage in front of me, as if someone was walking towards my area.

At that moment, almost all the cells in the body woke up.

Before my brain could react, my body took the lead, listening to the direction of the footsteps and hiding in the grooves where the two passages were connected.

The sound got closer and closer, and gradually, several shadows slowly appeared on the wall directly opposite the passage.

"I heard that the assassin caught someone outside tonight?" A heavy voice came slowly from my side, and at this moment, there was only a wall between me and the guy who was talking.

As long as they take a slight step to the right, they will be able to discover my presence.

Before I rescued Lu Yuan, I tried to avoid conflict with the personnel in the institute, which would undoubtedly put myself in a disadvantageous situation. Next, I pressed my body against the wall and controlled my breathing so as not to show the flaws.

"yes, that guy is pretty good, he can actually hurt the stinger."

"Is it the police, or the traitors?"

"I don't know, wait for the results of the interrogation in the confinement room. Assassinate that guy, he will definitely not give up, no matter where he is, that kid has to be done playing! “

"Don't be idle!" At this moment, a voice suddenly came from the other end of the passage, and it seemed that there should be another group of people, who also came over at the same time: "Dark Thorn asked you to come over and take a look at the situation, here in the outer passage, did you find anything wrong?" ”

"Brother, in a shabby place like ours, we haven't seen the sun for a whole month, how can anyone find someone to come in. The assassin caught that kid on the second floor of the office building, and even if there were other people, it was probably just tossing outside the office building! ”

"Don't mind, do you dare to follow the task assigned by the assassination? Just in case, let's go out and take a look, and by the way, call up the surveillance video outside the research institute to see what the situation is. Also, bring all the guys with you so you don't get into trouble! ”

As soon as the words fell, the footsteps of those people gradually faded away along the passage I had just entered.

By the time I came back to my senses, my back was already soaked in cold sweat. It's so dangerous, just a little bit close, they found out.

I didn't expect the situation here to be so complicated, and the guy called Dark Thorn is bound to be not an idle person.

Can I have a chance of winning against such a character?
