Unlimited studio survival, I have a proficiency panel

"I have no opinion."

Wang Shan spoke first, and then looked at Li Yue.

"Hand over the letter, I have no objection."

Li Yue couldn't help but look at Wang Shandao when he saw this:
"However, I think there may be some problems with Wang Shan's speculation."

"what is the problem?"

When everyone heard Li Yue's words, they all looked at him.

"I think it may not work for someone else's third letter to go upstairs after delivery."

"If I hadn't failed to send letters, maybe I would agree with Wang Shan's guess."

"But because of my failure to deliver the letter, one of my letter delivery quotas was deducted."

"It makes me think that the post office's rules for delivering letters are that three places must be filled. There is no such thing as a third 'letter upstairs'."

"After all, if there really is a 'letter upstairs', wouldn't the so-called three letter delivery quotas be unnecessary?"

"Of course, if you insist on explaining that the 'letter delivery quota' exists just to offset those who fail to deliver letters, that's not impossible."

"What really makes me think there is a problem with Wang Shan's guess is the post office's letter delivery mechanism."

"As far as I know, there are three types of post office delivery mechanisms."

"The first is personal delivery, and the letter will appear on the nightstand in the personal room."

"It means that the people in this room need to send a letter."

"Attention, everyone in this room has to deliver the letter."

"There is no rule in the post office room that only one person is allowed to exist."

"Sometimes if there are too many messengers on the first floor, seven rooms will not be enough, so multiple people will form one room."

"And at this time, the problem came."

"If we say that in this room, there is a person who has delivered two letters, and there are people who have only delivered one letter, and there may even be people who have not delivered a letter."

"Then the people in this room, the common letter delivery task, is it counted according to the letter sent upstairs by the person who sent two letters?"

"Or is it counted according to the second letter of the person who sent a letter, or according to the first letter that did not send a letter?"

"If you sent two letters according to the rules, wouldn't the person who sent the second letter, or even the first letter, be able to go upstairs directly?"

"That's obviously not right."

"None of this has ever happened."

"Same."

"The second situation where the post office delivers letters is in the corridor. The letters in the corridor represent the need for two or even more rooms to cooperate in delivering letters."

"It's pretty much the same as what I said above."

"It's normal to have different numbers of messengers. Under such circumstances, who is the standard?"

"In the last case of the sender, the letter appears directly on the counter in the lobby, which means that all couriers on the first floor must deliver the letter together."

"Although I have never encountered such a situation, but according to the news from upstairs, it will exist."

"Then whose standard is this based on?"

"There are three ways to send letters. As the number of people increases, the difficulty also increases."

"Based on this standard that cannot be judged, I think Wang Shan's guess has a big loophole."

"Wang Shan, the reason why you make such a guess is that after you came here, the two deliveries you experienced were only single-person letters, and you have never cooperated to deliver letters, so your guesses will be biased."

"Are there any other situations like this?"

"It seems that I thought it was simple."

Hearing Li Yue's words, Wang Shan thought for a while, and admitted the loopholes in his guess.

"According to this, don't we have to send honestly the quota of three letters?"

Hearing Li Yue's analysis, Li Tian had to admit that Wang Shan's thinking had big loopholes.

That is to say, the method of going upstairs quickly won't work for someone else's third letter delivery.

"Moreover, this ghost post office can't use the ghost domain to force it on the road."

Li Tian raised his head and looked upstairs.

The divine eyes on the forehead are peeping.

The result is that the perspective in the eyes of God is pitch black, shrouded in darkness.

There is no second floor, third floor, fourth floor, or fifth floor in the ordinary perspective.

Those are all illusions, or these floors do not exist in the places you see, but exist in another spiritual space.

Similar to the ghost domain in the... ghost domain.

Layer upon layer, interlaced and twisted.

"Obviously, the upstairs seen from the ordinary perspective is illusory, and reality is actually a kind of distorted ghost land."

"My five-story ghost domain has been affected in the ghost post office. Although you can still try to invade, it is easy to get lost in the interlaced ghost domain."

"The risk is too great."

"The people who built this ghost post office are definitely not simple, and they have blocked all the loopholes."

Li Tian looked a little dignified, thinking in his heart.

"Perhaps there are other ways to get upstairs quickly."

"It's just that we don't know."

Li Yue spoke.

"Forget it, don't think about it so much."

"By the way, when do letters usually appear?"

Li Tian shook his head and didn't think about it any more. He was going to read the so-called letter first, and send it once to understand it.

"It usually shows up tomorrow."

"The post office called us today, stay overnight at the post office tonight, and then the letter will arrive tomorrow."

Li Yue replied.

"Okay, then stay here for one night and see what happens to tomorrow's letter."

Li Tian decided.

Next.

Everyone is waiting.

Waiting for the post office to turn off the lights at 6 o'clock.

"Sun Rui, let's share a room tonight. As I said just now, multiple people can stay in a room."

"We'll send the letter together then and see what happens."

Li Tian looked at Sun Rui and said.

"Okay, listen to Team Li's arrangement."

Of course Sun Rui would not have any objections.

Li Tian and Sun Rui chose to randomly choose the empty room on the 14th.

Enter room 14.

Li Tian looked at the environment in the room.

Decorated in the style of the Republic of China, old-fashioned tiles, chandeliers, and slightly faded furniture.

The chandelier in the whole room emits dim light, covering the room, full of a dark style, which makes people feel very uncomfortable.

But that's not the point.

The point is that the layout of this room is exactly the same as the mysterious corridor room in the Caesars Hotel.

"The ghost post office is indeed related to the Caesar Hotel."

"Even though the functions of the rooms are very different, one is used to imprison evil ghosts, and the other is used to house people and protect the messenger."

Li Tian thought in his heart.

After paying a little attention to the structure of the room, Li Tian didn't think much about it.

Patiently waiting for the passage of time.

soon.

The time reaches 5:50.

Li Tian in the room suddenly looked at the door that was still wide open.

Li Tian deliberately did not close the door, just to see the changes outside the door of the post office at 6 o'clock in the evening.

At this time, strange changes took place in the old ghost post office.

The originally yellow light began to flicker gradually at this time, and the light became dimmer and gradually tended to go out.

In addition, a darkness seemed to be eroding all the way from the fifth floor of the post office. Wherever it passed, the lights in the post office were completely extinguished, making it impossible to see the surrounding scene clearly.

"This darkness?"

Li Tian looked at the darkness that shrouded the outside, and couldn't help narrowing his eyes.

Li Tian is very familiar with this kind of darkness.

It is very similar to the dark ghost domain on the knocker.

"Sure enough, there is a deep connection between the knocker and the ghost post office."

"The door knocker was the top ghost master during the Republic of China, the builder of the ghost post office, or the top messenger on the fifth floor of the ghost post office?"

"There is no doubt that the messenger on the fifth floor is the person closest to the secret of this ghost post office."

"The knocker fell to his death from the fifth floor before his death." "Therefore, it is really possible that the knocker was a messenger on the fifth floor."

Li Tian guessed in his heart.

At this moment, Li Tian was thinking, while watching the darkness enveloping him, he still didn't have the slightest intention to close the door.

He just wanted to see what kind of existence this so-called scary ghost wandering around in the post office, the ghost post office.

The reason why Li Tian dared to do this was of course because of his own strength.

To these ordinary messengers, Li Gui might be terrifying, but to Li Tian, ​​that's all.

Even if the wandering ghost is an S-level ghost, Li Tian may not be afraid.

It's a big deal to fight if you don't accept it.

"Captain Li, don't we close the door?"

"I feel the darkness outside, very dangerous."

"We don't need to deliberately violate the rules of the post office and take the initiative to face the ghosts, right?"

Compared with Li Tian's boldness and calmness, Sun Rui seemed a little nervous.

Even if he controls two ghosts, he doesn't want to fight against the ghosts easily.

After all, in his opinion, people cannot fight ghosts.

The immortality of ghosts, and the fearlessness of consumption, doomed ghost masters to an absolute disadvantage.

Moreover, the ghost post office is not ordinary at first glance, and the ghosts in it must not be ordinary ghosts, they are definitely terrifying existences.

"You don't have to worry, I have a measure."

Li Tian waved his hand and said.

"Ok."

Seeing Li Tian's insistence, Sun Rui had no choice but to watch nervously outside the door, which had become dark, to guard against the possibility of a sudden appearance of a ghost.

Step, step, step~!

Crunch, crunch~!

At this moment, the sound of dead footsteps suddenly echoed in the darkness outside the door.

That was the sound made by the corpse stepping on the wooden plank. After a while, the "creak" sound of stepping on the rotten wooden plank was clearly transmitted.

Obviously, there are ghosts approaching.

"Team Lee."

When Sun Rui heard footsteps outside, the tension in his heart suddenly reached its peak.

He knew that the outside must be a ghost, so he couldn't help shouting at Li Tian, ​​reminding him:
"A ghost is really here."

"I know."

Li Tian stood at the door, his eyes opened on his forehead, emitting a strange purple light, trying to see through the darkness.

But it still failed.

The power in the ghost post office is very terrifying. The suppression is already very strong when the lights are on during the day, and it is even more enhanced when the lights are off.

Li Tian even felt that his fifth-level ghost domain could not spread out on a large scale.

It can only cover a small range.

Not even the walls can be penetrated.

"This ghost post office is even more powerful than I imagined."

"This kind of darkness outside the door is also much more terrifying than the dark haunted world of the strong knocker."

Li Tian felt that his divine eyes were being suppressed by the ghost domain, and he couldn't help squinting his eyes.

Li Tian stood inside the door of room 13, with his strange purple ghost eyes open, and the faint purple light pierced through a distance of several meters around him, waiting for the ghost that made footsteps to come over.

Step, step, step~!

The sound of footsteps was getting closer.

With the approaching footsteps, the darkness is also oppressing.

At this moment, the darkness outside the door of room 13 has already pressed into the room from outside the door.

The dim light in the room was dimming.

Li Tian, ​​who was standing at the door, was once again oppressed by the purple light ghost domain emitting at this moment, which could only cover a distance of one meter around him.

"Are you coming?"

Li Tian didn't care about this, and didn't mean to back down at all. The hand ax appeared in his hand, ready to fight the upcoming ghosts at any time.

Sun Rui on the side didn't dare to breathe anymore, he felt a strong threat in his heart.

There is no doubt that the ghosts outside are terrifying!
"Tread, step, step!"

The sound of footsteps outside became clearer.

It can already be judged from the sound that the location of the thing is in the corridor outside the door. This corridor is not big. If you do some calculations in your mind, you should be able to judge that the footsteps are probably at the location of rooms 11 and 12.

at this time.

Wanxing and Qian Rong in rooms 11 and 12 had already held their breath.

Apparently they also heard footsteps outside the door and knew that a ghost was coming.

They prayed in their hearts that the ghosts outside would not come to them.
Seems like prayer did the trick.

Li Gui's footsteps did not intend to stop.

After passing through rooms 11 and 12, it should be the location of room 13.

Room 13 is empty, and it's obvious that the evil ghost won't stop.

And Li Tian and Sun Rui are in room 14.

Immediately the ghost is coming.

"Captain Li, it looks like this ghost is coming for us."

Faced with this tense atmosphere, Sun Ruijie held his cane and couldn't help but speak again.

Li Tian ignored Sun Rui's intentions and stared at the door.

A little bit.

This ghost is about to enter Li Tian's purple light ghost domain with only one meter left.

Once Li Gui stepped in, Li Tian would dismember Li Gui without hesitation.

at this time.

"Stopped."

Suddenly.

The footsteps outside the door stopped, and at this moment Li Tian could clearly feel that there was something standing outside the range covered by the ghost domain within one meter of his own.

It seems that the ghost has already sensed the existence of Li Tian's ghost domain, found the danger, and is unwilling to step in again.

"No, it should be some kind of law."

"Does this ghost only exist in the dark?"

Li Tian's thoughts turned, and he quickly guessed the reason why Li Gui stopped.

"If you don't come, then I'll go out and find you."

Li Tian's heart moved, and as soon as he stepped on his feet, he was about to go out, take the initiative to meet the ghost, and pull the ghost into his ghost domain.

but.

Li Tian has not moved yet.

An incredible thing happened, which made Li Tian's hair stand on end instantly, and a feeling of horror surged out of his heart.

"Boom, boom, boom."

A depressing, dull knock on the door sounded.

The voice was familiar.

correct.

It is the way of the door knocker to kill.

Knock to kill.

"How is it possible? The knocking sound of the knocker?"

Li Tian was stunned when he heard the knock on the door, his mind was filled with disbelief.

The knocking ghost has clearly been imprisoned by him personally, and now it is placed in his own water flow space, how can there be a ghost knocking on the door?
You must know that since ghosts in the real world appeared in this world, there have never been two identical ghosts.

"Wait, this is not knocking on the door to kill someone. Neither Sun Rui nor I were attacked by the knocking on the door..."

Li Tian reacted suddenly. He looked at Sun Rui beside him. He had not been attacked.

"Ghost knocking?"

At this time, Sun Rui also heard the knock on the door outside, and his complexion changed drastically:
"Did the A-level knocking ghost incident come to the ghost post office?"

"But according to the intelligence, isn't the A-level ghost knocking on the door incident raging in the island country now? Why did it suddenly appear here?"

"Besides, our door is clearly open, and the door is facing inward. How did the ghost outside knock on the door?"

Sun Rui was filled with doubts at this time.

Apparently Ya had paid attention to the door-knocking ghost incident.

But he didn't know that the knocker had already been dealt with by Li Tian and Yang Jian.

What's more, the knocker doesn't necessarily need the door to knock on the door. It is actually enough to raise your hand to knock on the door. (end of this chapter)
