Yang Jian suspected that the opera sung in room 505 was the one they heard when they were on the fourth floor.
In other words, when they were on the fourth floor, the "person" they heard singing opera outside the post office was probably in room 505 at this time.
So, it is basically certain that what is in room 505 is a fierce ghost.
Yang Jian then told Yue Li his suspicion.
But after Yue Li listened, he shook his head repeatedly after a slight silence;
"I think you may have misunderstood. I can clearly hear that there is no real opera singing in Room 505. It's more like an old record player playing opera."
Although it was a bit difficult to understand, Yue Li could clearly hear that the sounds coming from Room 505 had a sense of age.
Hearing what Yue Li said, Yang Jian was stunned for a moment, but then relaxed a little.
After all, the person who was singing outside the post office was basically a ghost. If it was really in this room, they had to consider the danger.
Now that Yue Li said that the noise in the room was not caused by a ghost, the risk will naturally be much smaller.
But Yue Li continued to say:
"Although there are no ghosts singing opera in the room, the opera itself should be related to ghosts, so we cannot let down our guard."
It's okay for ordinary people to speak, but if it has something to do with supernatural beings, then the voice can also kill people.
And it’s even more difficult to guard against.
Although Yue Li could not perceive the real effect of the opera due to the isolation of the room door, he also had supernatural abilities related to sound and instinctively sensed that the opera in the room was not simple.
After Yang Jian heard this, his attitude immediately changed.
He himself has mastered the curse of the music box, so he naturally knows that the sound can also become very terrifying.
Especially now that the sound of this opera is still spreading in the post office, it will naturally not be simple.
"Then should we go in and explore it?" Yang Jian was a little unsure of Yue Li's thoughts.
To be honest, Yue Li was still a little curious about the sound of opera coming from this room, and he did think about entering this room to explore.
Yue Li even suspected that the ghost who was singing opera outside the post office might have been attracted by the sound of opera in Room 505.
Although it was just a guess, Yue Li really felt that this possibility was very high.
If we could figure out the opera sound in the room, we might be able to get information about the evil ghost singing outside the post office.
As for the fierce ghost singing outside the post office, Yue Li was still a little jealous.
After all, the post office itself is not simple, this is Luo Wensong's territory.
The opera ghost can wander outside the post office but cannot be dealt with. This already shows how powerful and terrifying this ghost is.
If it can be swallowed and digested, it will not only enhance the supernatural power of the aquarium, but it may also inherit a powerful supernatural ability.
Thinking of this, Yue Li suddenly had the urge to enter Room 505 and explore.
"Creak!"
But just when Yue Li was about to open the door, a subtle sound of opening the door suddenly sounded in the hall.
Although the sound is not loud, because the entire hall is very quiet, even very small sounds are very obvious.
Yue Li immediately stopped what he was doing and turned to look at the place where the sound came from.
I saw the door of Room 502 suddenly and slowly opened half a crack.
Yue Li's eyes suddenly changed.
But before he could say anything, the middle-aged man they had seen before who was not in good health and had a bit of a cough slowly appeared.
The man stood gloomily behind the door, half of his body exposed.
He looked at Li Yue and Yang Jian with a somewhat strange expression.
It seemed that the darkness in the hall could not stop this man.
Seeing the man in room 502 appear, Yue Li and Yang Jian immediately looked at each other.
None of them spoke rashly or took any other action, just quietly observing Room 502 and the man.
Through the ghost eyes, Yue Li clearly saw that the lights in room 502 were darker than those in other rooms.
It's like some of the lights in the room have been turned off, and only some of the lights are still on.
So it's not enough to light up the whole room.
Moreover, Yue Li also noticed that the remaining lights in Room 502 flickered from time to time, which looked particularly strange.
It seems to represent some special symbol.
The man in room 502 didn't seem to expect that Yue Li and Yang Jian could be so tolerant and didn't even speak.
In the end, the man could only speak first:
"I suggest you don't try to open the door randomly at night, as this could cause serious trouble."
Facing the man's proactive reminder, Yue Li still didn't say a word, but still looked at the man with indifferent eyes.
However, Yang Jian on the side had a flash of light in his eyes at this moment;
"During the day, I thought you were a ghost, but now it seems that with the lights out in room 501, it's more likely that there is a ghost in there;
Although there seems to be something wrong with the lights in your room, at least they are still on, so the possibility of you being a ghost is smaller."
After hearing Yang Jian's words, the man in room 502 did not show any unnecessary expressions or make any other movements.
Still standing behind the door of Room 502, looking at Yang Jian and Yue Li quietly.
Seeing this, a strange color flashed through Yang Jian's eyes again.
Similar to Yue Li's thoughts, although now it seems that the man in room 502 is more credible.
But Yang Jian would not really trust this person completely.
So what I just said is actually a kind of temptation.
I wanted to see how this man would react after hearing his judgment.
Unfortunately, I don’t know if this man saw through Yang Jian’s thoughts, or if it was for other reasons;
The man didn't react at all, so Yang Jian naturally couldn't make any further judgments based on the man's reaction.
Although Yang Jian was disappointed when he saw this, he did not show any signs of it and continued to ask:
"You just said not to open the door randomly at night, as this could cause serious trouble. Can you explain the reason in detail?"
Obviously, Yang Jian is still testing this man.
Of course, it is not just a simple test, but also to obtain more information.
Facing Yang Jian's inquiry, the middle-aged man in his early fifties answered after a moment of silence:
"In fact, during the mission of delivering messages, the messenger on the fifth floor will inevitably provoke some terrible ghosts;
Although the ghost post office is very special and can block the invasion of most evil ghosts and ensure the safety of the courier;
But this is not absolute after all.”
Faced with the man's statement, Yang Jian naturally understood it.
Let’s not talk about the far ones, let’s talk about the previous fourth floor. Wasn’t it invaded by intruders?
Because of this incident, the ghost post office began to clean up the messengers on the fourth floor on a large scale. It was not until Yang Jian, Li Yue and others went up to the fourth floor and imprisoned the invading ghosts that the incident was considered over.
But even so, the couriers on the fourth floor basically suffered heavy casualties.
