Professor Wen opened the door and glanced into the corridor, as if he was afraid that the partition wall had ears, and confirmed that there were only two people here, or at the current floor, he and Mo Chen.

Professor Wen pushed down his glasses and said in a low voice, "Don't you think Li Chao seems to know the situation here?" As he said this, Professor Wen raised his hand and pointed down with his index finger to the ground, meaning that this room was in this room.

When he came up, Li Chao tried to dissuade him, and Mo Chen felt that he was a little strange.

Although Li Chao later explained that he was afraid of the smell of disinfectant water in the hospital, this reason was too unconvincing.

Mo Chen nodded, "But it's obvious that he is reluctant to tell us the truth." ”

Professor Wen said, "We should pay more attention to the words of this NPC brother, and deliberately arrange for him to appear next to you and me, there must be his intentions." ”

"It's nature." Mo Chen said.

Immediately, Mo Chen expressed his opinion again, he felt that Li Chao dissuaded him at that time, not to go upstairs to check the situation, not really did not want him to come.

On the contrary, it is deliberately emphasized that it is too dangerous to go it alone!

The three of them were together, and he Li Chao was willing to accompany him, so it seemed that he was deliberately saying this to Professor Wen.

Although Professor Wen is knowledgeable, he is over half a hundred years old, just like when he is in the operating room, when he really encounters danger, he not only cannot become Mo Chen's helper, but is a protected role.

So Li Chao, what is the purpose of asking Professor Wen to accompany him upstairs?

Could it be ...... What Li Chao really wants is to act alone?

Mo Chen expressed his thoughts, but when talking about Professor Wen's physical strength and age, Mo Chen tried his best to be tactful.

"Hmm...... This is really strange. Professor Wen agreed with Mo Chen's idea, and he asked Mo Chen, "Then according to you, should we continue to go upstairs?" Or do you want to kill a horse pistol? Perhaps, we will go back suddenly, just in time to bump into his absence. ”

Mo Chen looked sideways and thought for a moment, "Forget it!" This is my guess after all, since we are here, we should go upstairs first, there is no need to toss back and forth, wasting time. ”

Professor Wen was the first to walk out of the room, and when Mo Chen was about to go out, he casually took a syringe that was thrown in the corner.

In the syringe forty or fifty centimeters long and the thickness of the little finger, there was a half-tube of turbid liquid.

Mo Chen was sure that this was the group of people in the house, who had injected drugs before their deaths.

Mo Chen took away this half-tube of venom, not that he was also an "addict" with this hobby, he just had a whim, and it was not bad to keep this thing for self-defense.

Mo Chen and the others walked into the stairwell again and climbed up the stairs to the fourth floor, but what people didn't expect was that after the stairs reached the fourth floor, there was no way to go.

A dilapidated iron gate stood at the end of the stairs, and through the fence of the iron gate, Mo Chen shone it with a torch, and on the inside of the iron gate was a huge iron bucket.

A large black lock hung on the iron gate, and a name sign hung half-off on the fence, which read "Boiler Room".

"Looks like this is the end of our expedition." Professor Wen quipped.

Mo Chen tugged at the corners of his mouth in disappointment, have they completely explored all the secrets of this hospital?!

Mo Chen still had a strange feeling in his heart, and he always felt as if something was missing.

"Let's go!" Professor Wen said this, then turned around and went downstairs with a torch.

Mo Chen was about to follow, and the moment he turned around, he suddenly remembered something.

Mo Chen suddenly shouted, "Wait a minute!"

"Huh?" Professor Wen stopped and looked at Mo Chen suspiciously.

Mo Chen said excitedly, "That's not right! I remember that when we came here to shelter from the rain, we were outside the building, and what we saw was obviously five floors.

And just now, we only walked three floors, even if this boiler room is the fourth floor, that is still one floor away. ”

Being reminded by Mo Chen, Professor Wen also suddenly remembered this detail, and then he withdrew his steps, walked to the iron door, and tried the big lock on the door, the world inside the door was still firmly bound.

Mo Chen carefully held the torch and reached into the fence door, and the firelight immediately illuminated the so-called boiler room.

The huge iron bucket goes up to the roof of the shed, but it can be determined that the lifting frame on this floor is no different from the three floors below, which precludes the possibility that one floor occupies two floors.

On the inside of the bucket, which is in the opposite direction to the door, there is a solid wall and no windows.

So what happened to the windows on the fourth and fifth floors that Mo Chen saw outside the building?

Paranormal events?!

In Mo Chen's mind, this idea jumped out of his mind for the first time, he had seen this type of thought when he was a student.

The protagonist of the story, the floor he sees, is always different from the floor he can reach.

Could it be that this kind of thing happened to Mo Chen today?

"Could it be...... On the back of this boiler, there is also a passage that can reach the real fourth and fifth floors? Professor Wen said.

Mo Chen carefully looked at the "big iron bucket" that reached the roof of the shed, maybe it was really as the professor said, on the back of the back that they couldn't reach, there was really a secret door and entrance?

"I'm going to look for tools and see if I can break this lock." Mo Chen said that, and walked back to the third floor quickly, leaving Professor Wen alone in front of the iron door to look curiously.

Regardless of whether there were tools in the operating room or not, Mo Chen didn't want to go any further, compared to the thirteen corpses in the chief physician's office, the corpses of the virus-infected people in the operating room were more terrifying.

No matter how brave Mo Chen is, there is no need to risk his life, but fortunately, there is a storage room next door to the chief physician's office.

Mo Chen was at the bottom of the shelf full of medical staff's uniforms, and unexpectedly found a special toolbox for electricians, which happened to have a pair of iron pliers in the toolbox.

Mo Chen grabbed the pliers and clamped them twice, feeling that he could almost break the lock, after all, the lock only looked big, but in fact it was used to hang the U-shaped part on the door, which was pitiful.

After getting the tools, Mo Chen turned around and ran back to the fourth floor, but at this moment, his little heart couldn't help but chuckle.

There was no shadow of Professor Wen in front of the iron gate, if it was all there was to it, Mo Chen could comfort himself.

Perhaps after he went downstairs, Professor Wen followed him downstairs to help rummage through the tools.

But at this moment, Mo Chen couldn't convince himself like this, because ...... Professor Wen's torch fell on the edge of the iron gate.

Mo Chen picked up the professor's torch and pinned it to the fence, so as not to accidentally cause a fire.

Mo Chen tried to call "Professor~~" Not surprisingly, there was no response from Professor Wen.

Where did Professor Wen go? The torch fell to the ground, indicating that the professor was in a panic.

But Mo Chen was on the third floor just now, even if there was a noise of rain outside, it wouldn't be a sound at all, right!?
