So, Cao Ya and the others discussed it and decided to stay and go into a room to see the actual situation of the Ghost Post Office before discussing their next move.

Since Cao Ya and his group forced their way in, it's best for the four of them to stay in one room just in case, so they can be prepared to deal with any unexpected situations.

The ghost post office tonight is unlikely to be peaceful.

They chose Wang Shan's room.

Wang Shan's expression changed slightly as he repeatedly objected, but to no avail.

The group adopted a defiant attitude and entered room 17.

Wan Xing and the woman named Qian Rong swiftly entered room 11 and slammed the door shut.

Inside room 17.

Cao Ya stood at the doorway, spreading his senses to detect any movement outside.

At six o'clock sharp, the lights in the post office were completely turned off, and darkness enveloped the entire post office, plunging it into a deathly silence.

Even the neon lights next to the sign outside the door were dim and lifeless.

However, at this very moment—

Inside the eerily silent ghost post office, a heavy, deathly footstep echoed.

That was the sound of a corpse stepping on a wooden plank, creaking and groaning as it drifted over, barely audible.

Moreover, the sound was very strange. When it was on the fourth floor, it only echoed on the fourth floor. There was not a sound downstairs at all, and you couldn't hear anything even if you strained your ears.

Cao Ya, however, paid no attention to the commotion, focusing instead on probing the surrounding atmosphere.

A chilling aura slowly appeared on the first floor; needless to say, he knew it was a vengeful ghost.

At this moment, the others also heard the heavy, lifeless footsteps, and their expressions changed slightly.

Yang Jian looked around. The room's decor was exactly the same as the Caesars Hotel he had visited before. The powerful supernatural item he carried with him—the old rusty woodcutter's knife—was something he had snatched from the jaws of death at the Caesars Hotel.

"What is the connection between the two?" Yang Jian pondered.

The Ghost Post Office and the eerie Caesars Hotel are products of the same era.

"Five people in the room, all men, and only one bed. How are we supposed to sleep? If word gets out, we're doomed." Sun Rui stared at the wooden bed in the room and couldn't help but complain.

"Let's just make do for one night. Something's not right here, especially after the lights were turned off," Li Yang said.

Wang Shan secretly curled his lip. This room is for me alone. Who told you to squeeze in?

There are clearly several empty rooms.

"Shh!" Cao Ya gestured for everyone to be quiet.

The old wooden door was warped, and even when closed, it wasn't completely shut, leaving a finger-thick gap. Through those gaps, he could clearly see the pitch black outside. This darkness seemed to have materialized, even seeping in slightly.

A peculiar darkness, the power of a vengeful spirit?

Cao Ya gripped the doorknob, looking as if he was about to rush out at any moment.

Sun Rui glanced at him:

"Cao Ya, don't tell me you're going to risk rushing out, are you?"

Cao Ya shook his head and stood guard by the door, sensing the movement outside.

Seeing that there was nothing unusual, Sun Rui and Li Yang started chatting. He mentioned that he had previously written a paper about vengeful ghosts, but it was rejected by headquarters. They subtly said that his paper lacked corresponding practical evidence, which basically meant that he was talking nonsense.

Judging from Sun Rui's words, he really put a lot of effort into that paper. He also said that he wrote a book called "I Am the Head of Dahan City," which is his autobiography. He has contacted a publisher and plans to print millions of copies, guaranteeing it will be a bestseller!

He also said that if they were willing, he could write a biography for each of them, guaranteeing it would be excellent, and then publish them together, sure to dazzle those ghost tamers.

Yang Jian told him to stop talking nonsense. If he released his autobiography, wouldn't that be leaking his information?

Wang Shan stayed quietly in the corner, not daring to interrupt.

He is not a ghost tamer.

However, when the others asked him questions, Wang Shan dared not refuse to answer.

According to Wang Shan, he had heard from the messengers upstairs that there was a staircase on the fifth floor of the post office that led outside, which was probably the only chance for the messengers to escape this awful place.

He said he had no choice but to take a gamble.

Staying here will only lead to his death sooner or later. He doesn't have the power to control the evil spirits, and if he delivers messages too often, he'll inevitably run into ghosts.

Therefore, Wang Shancai helped these people in the hope that they would help him in the future.

Wang Shan confessed everything without hiding anything, which dispelled the concerns of several ghost tamers.

Wang Shan understood that in front of the ghost tamer, he was just an ordinary person, the kind who had no power to resist at all.

Moreover, these responsible persons do not have to bear any responsibility after killing themselves.

In those extraordinary times, the power of those in charge became boundless.

Correspondingly, those in charge also need to deal with paranormal events, risking their lives.

Wang Shan also said that during his time as a messenger, he had carefully reasoned and studied, and discovered a loophole in the way upstairs.

This method is impossible for ordinary people; they would die a terrible death. Only special people can do it.

The special people here naturally refer to the ghost tamers.

According to Wang Shan, each messenger needs to complete three delivery tasks before going upstairs. However, the time each messenger enters is different, which leads to a problem: some people have delivered two letters, while others have only delivered one, and some have not even delivered a single letter yet.

Are experienced and newbies on the same floor? Does the post office want experienced people to mentor newbies?

Clearly, the ghost post office isn't all that kind.

Therefore, there is only one explanation: the post office wants to help newcomers rise through the ranks more quickly.

"Going upstairs, the key is not how many letters were delivered, but whether or not that crucial letter to the upstairs person was delivered."

Wang Shan spoke earnestly, showing none of the youthful exuberance typical of his age; on the contrary, he was very calm.

"The third letter in each messenger's hand is the letter to go upstairs. If the person who snatches it and delivers it comes back alive, then that person can replace the original messenger and successfully go upstairs."

"As a price, the number of times the messenger can deliver letters may be reset to zero, and you will need to start over by delivering three more letters. Or perhaps we can all go upstairs together."

Wang Shan was also unaware of this, as it was merely his speculation and he had not personally experienced it.

“I’ll be assigned to the third letter soon. Wan Xing is the third letter, but that woman named Qian Rong has only delivered one letter, which doesn’t meet the requirements.”

Cao Ya listened for a while and then laughed:

"It's okay. As long as the road appears, anyone who wants to go up can go up."

The appearance of a path leading to the second floor signifies a temporary connection between the supernatural spaces separating the first and second floors.

The passage has appeared, so why can't Cao Ya break in?

He just can't figure out the exact coordinates of those floors located in other supernatural spaces.

It was just a vague, indistinct feeling.

Wang Shan was taken aback. He looked at the other three people and saw three pensive faces. He began to doubt his own existence. Were all ghost tamers this confident?

Suddenly, Cao Ya's ears twitched.

"Quiet, something's coming."
