After an unknown amount of time of exploration, as the layout of the rooms that appeared appeared more and more consistent with the drawings, both Han Zhen and Chu Feng gradually showed relaxed expressions on their faces.

Along the way, Kaichi never encountered another attack from that faceless monster, and the originally tense atmosphere between the two people also eased a lot.

After some questioning and talking just now, Chu Feng also determined that the next goal is to find the exit first, try to send Han Zhen out of the building, and then find the route to the high-rise according to the original plan, rather than trying to rescue him.

The missing Fang Qin.

However, if possible, he still hopes that Han Zhen can stay and help. After all, he has always believed that just because he has not encountered monsters does not mean that the place is really safe.

If he was attacked by those things after being separated from Han Zhen, Chu Feng would still feel a little unsure.

However, Han Zhen's attitude just now made it clear that he did not want to get involved in this dangerous matter, which made Chu Feng unable to speak.

Just when he was debating whether he should take advantage of the situation to ease slightly and ask for help again, Han Zhen, who had been walking in front, suddenly stopped.

Chu Feng, who was thinking about the matter in his mind, couldn't stop for a moment and almost bumped into the opponent's back. Fortunately, he reacted in time and stopped. Then he asked with a slight hesitation: "What's wrong?"

"There is a sound ahead." Han Zhenyan replied concisely, and in front of him was a corner outside the wall. At this time, Han Zhenzhen was stopped behind the corner, and his sight was blocked by the wall, so he could not see what was behind the corner.

Sound? Could it be those monsters again?!

Chu Feng was shocked, and her nerves, which had been relaxed because she had not been attacked, became tense again.

But before he could react, Han Zhen blurted out again: "It shouldn't be those monsters, it seems to be the sound made by some machine."

When Han Zhen said this, his back was turned to Chu Feng, who was behind him, so the latter did not see the thoughtful and confused expression on his face.

But after he finished saying this, Chu Feng, who had remained silent for a moment, also vaguely heard a strange sound like the ticking of the pointer of some kind of precision instrument coming from behind the corner of the wall, but the sound was extremely subtle.

It seemed a bit intermittent, so just now it was completely covered up by the footsteps of the two people moving forward. It was not until he stopped and kept quiet that Chu Feng barely heard a little bit.

This sound…

"Somewhat familiar!?"

"Where have you heard it?"

The two of them said this almost in unison. The next moment, Chu Feng's pupils suddenly widened. He seemed to suddenly think of something. He pushed away Han Zhen who was blocking the front and rushed towards the corner of the aisle ahead.

go out.

Han Zhen quickly stepped aside to get out of the way when Chu Feng reached out to push him. Then he noticed that Chu Feng, who had been following him, rushed forward quickly.

Suddenly, he realized something and stepped forward to follow Chu Feng's figure.

Walking out from behind the wall at the corner, the narrow corridor only continued for three to five meters before suddenly opening up.

A broad hall appears

In front of the two of them, the wall of the hall near the exit of the corridor was still a bloody red reflected by the red light projected in the corridor. However, farther away, the red light gradually weakened, but it fell into darkness, which could only be blurred.

See the outline of the room clearly.

That strange ticking sound was coming from a strange-looking machine in the center of the empty hall. At this time, there were two signal lights, one red and one green, flashing intermittently on the machine. The faint flash seemed to happen at any time.

Will interrupt normally.

The moment he saw the strange instrument clearly in the dim illusion, Chu Feng rushed over quickly, bent down and picked up the instrument with the screen from the ground.

At the same time, Han Zhen, who was following him, also remembered the strange and familiar ticking sound. It was the strange instrument with unknown purpose that he saw in the lobby on the first floor when he entered the building.

But compared with that time, the flashing red and green light spots on the instrument seemed much dimmer at this time, and even the continuous ticking sound was much weaker, as if it would lose power and stop running at any time.

"Have you seen this thing?" Han Zhen, who was following Chu Feng, was the first to ask.

"The magnetic field detector can measure changes in the magnetic field within a certain range." Chu Feng did not turn around, but stared solemnly at the pointer jumping back and forth on the dial of the instrument in his hand, and answered Han Zhen's question in a thoughtful tone.

"What does detecting a magnetic field mean, and why is there such a thing here?" Han Zhen continued to ask.

This time, Chu Feng finally looked back at Han Zhen and replied quickly: "I brought it in. There is a saying that ghosts are just hallucinations caused by changes in the geomagnetic field affecting the human brain, so I brought this machine.

Detect the magnetic field inside this building, but I left it in the lobby on the first floor before, I don’t know why it appeared here.”

Hearing his explanation, Han Zhen was stunned for a while, but then he reacted and said urgently: "That means this corresponds to the lobby on the first floor? Can we go out directly from here?"

Chu Feng was still immersed in the shock of seeing this magnetic field detector just now, but when he heard Han Zhen mention the topic of going out, his expression froze again.

He raised his head and looked around. Except for the faint red glow from the corridor where the two people just walked out, the whole room was empty and dark.

However, from this fuzzy gray scene, Chu Feng could still barely discern that the overall layout here was similar to that of the lobby on the first floor of the building.

And Han Zhen's sight had even penetrated the darkness and saw the two closed doors on the wall at the other end of the room. They were two huge sliding doors that opened on the left and right. Different from the wooden doors they passed through all the way, whether they were

Both the height and width are much larger. What's more important is that the material of the door doesn't look like wood. Instead, it looks like a translucent glass material. What's strange is that the glass door should be transparent. Even with Han Zhen's eyesight,

I couldn't see what was behind the door, I could only see a dense darkness that couldn't be broken.

At this moment, Chu Feng spoke again: "Being able to see the instruments I left behind here at least proves a guess, that is, we are still inside this building. As for being able to escape from here, it is just a matter of time.

My guess is, if you want to leave, you can try to find an exit in the hall."

Obviously, Chu Feng did not have the ability to see clearly in the dark, so he had not yet noticed the two strange doors on the opposite side.

"Show me the drawings." Han Zhen spoke again.

But Chu Feng only thought that he was going to find an exit, so he handed over the drawing in his hand without hesitation.

However, Han Zhen just unfolded the drawing and took a look at the lobby on the first floor, and was able to roughly confirm that the direction corresponding to the two strange sliding doors was the original door leading to the outside on the first floor of the building.

"I think I found the exit."

Confirming his suspicion, Han Zhen spoke directly.

"What?" This time it was Chu Feng's turn to be surprised, and then he saw Han Zhen put away the drawings and walked towards the wall on one side.

Suppressing all the strange thoughts in his heart, he quickly followed Han Zhen's footsteps and walked in that direction.

As the distance got closer, Chu Feng gradually saw the two glass sliding doors that revealed a pitch-black darkness.

When the two finally came closer, looking at the substantial darkness behind the door, Chu Feng's Adam's apple squirmed and asked with some uncertainty: "Are you sure...this door leads to the outside?"

"Not sure, but I have to try. After all, this is the only different room we have found so far, and these two doors are obviously different from the previous wooden doors."

"Okay, I'll open the door. If there is an exit behind the door, you should go out from here first. I hope you will help us notify the police when you go out."

Hearing that Chu Feng wanted to take the risk of opening the door, Han Zhen looked a little weird, but his expression was well concealed by the dimness in the room and was not noticed by the other party.

Immediately, Han Zhen did not hesitate and said "Okay" briefly.

Hearing that Han Zhen agreed to his plan, Chu Feng suppressed his racing heart and stretched out his hands with stiff muscles to grasp the handles of the two doors.

As his fingertips got closer to the doorknob, scenes of horrifying scenes kept lingering in his mind.

Some are the scenes of being attacked by the strange black mist behind the wooden door, some are the bloody tentacles crawling all over the wall, some are the ghost fetus with its bloody mouth open, and some are the faceless monster with the weird red light reflected on its body...

The more complicated his thoughts became, the greater the fear in the play became. Unknowingly, his outstretched arms were trembling slightly.

In the end, Chu Feng's hand landed on the metal door handle. The handle was solid and cold, without any warmth.

Taking a deep breath, Chu Feng finally looked back at Han Zhen behind him, but his expression was hidden in the darkness and could not be seen clearly.

Clenching his teeth, Chu Feng seemed to use all his strength to push them forward.

Without encountering any obstruction, he easily pushed the glass door open. He even used too much force and even rushed forward with his whole body, almost falling down.
