The light at the end of the stairs was dimly yellow, like some kind of kerosene lamp or candle.

Hu Kai couldn't help but wonder even more, why did the lights appear? Is there a person living in this underground building? If so, who would it be?

With all kinds of doubts, Hu Kai took the two ladies and cautiously walked up the steps.

At this time, there are more and more cluttered items on the steps, and torn shoes and clothes are everywhere. Because the debris has been left for too long, it is all moldy, rotten and smelly, and when it smells in the nose, it smells a little worse than the stinky water.

There were only a dozen steps of stairs, and when they reached the top, the debris in front of them was piled up like a hill, almost reaching the roof, blocking their way.

Hu Kai could only peel off the top layer and climb over the garbage mountain.

There are many types of garbage, like a small garbage dump, and there is everything in it. For example, old-fashioned bags, tattered clothes, cosmetic bags, fake head coverings, and women's intimate clothing.

Because many things have been rotten and moldy, they suddenly opened up, and they actually emitted a rotten smell like methane, and they quickly covered their mouths and noses.

He looked closely underneath him, and fortunately, although the smell was unpleasant, at least there were no cockroaches, rats, bed bugs and other things that should be human.

Unexpectedly, just when Hu Kai looked down, he found an extremely special item among the many miscellaneous items at a glance.

On a pair of jeans that were so torn that only the waistband of the pants remained, Hu Kai suddenly saw a cruise card!

That's right!

A dark blue magnetic card, connected by a delicate keychain, with the other end tightly fastened to the nose of the trousers.

How...... How can it be?

Suddenly, Hu Kai felt as if he had traveled through time and space, which was incredible.

Because, this blue magnetic card turned out to be exactly the same as the cruise card on his body!!

That's right!

In the center of the card is engraved a clear Neptune LOGO icon, which is obviously the exclusive cruise card on the Neptune. This card represents the identity of the passengers on the cruise ship, and can be used as a key to the room card, as well as for bill payment, rental, and boarding and disembarkation registration.

"What's wrong, Mr. Hu?"

Tingting found that Hu Kai was lying on the garbage for a long time and did not move, so she quickly asked in a whisper.

"Shh......h

Hu Kai sighed, and with the help of the faint light, continued to check the card. At this moment, his mind was full of doubts, and he couldn't understand more and more, what was going on?

In fact, there is nothing strange about picking up a cruise card. What's strange is that this is actually a cruise card for the Neptune!

At first, Hu Kai thought that it could be that some tourist on the Neptune left his clothes here and was picked up by him?

However, at the moment, these jeans are really badly damaged! Not only was it broken, but its trouser legs had clearly rotted away from age.

This magnetic card is also rusty and mottled, and it seems that it has been lost here for many years.

But...... How can this be explained?

You know, this is the first voyage of the Neptune? There is only one such cruise ship in the world called Neptune, and its cruise card is naturally unique!?

However, in this dark underground corridor, how could another Neptune cruise ship card appear?

What the hell is going on?

It stands to reason that the situation is critical at the moment, and Hu Kai should not delay time from this small card. However, Hu Kai faintly felt that this card was full of strangeness and seemed to be very important.

So, after signaling Tingting and the others not to worry, he carefully checked the card boy.

But I saw that the card was full of stains, but the basic information on it was clearly visible. The most obvious on it are the three big characters "B67". Hu Kai knows that these three words represent the lifeboat number, once the cruise ship is in danger and needs to abandon the ship, the owner of the card can use this card to take the lifeboat.

In addition, the card also contains the restaurant and table number, meal time, account and room number, etc.

“509？”

Hu Kai muttered quietly, "509" represents the room number. However, as far as Hu Kai knows, on the fifth floor of the Neptune, there are no tourist rooms at all, but a whole floor of commercial shops, all of which are shops such as video game rooms, SPA experience halls, and cigarette hotels.

Seeing this information, Hu Kai couldn't help but be even more puzzled, why did the card in front of him indicate that there was no guest room on the fifth floor?

Don't...... N years ago, there was another Neptune that didn't work?

That's right!

Hu Kai suddenly thought that the cruise card was marked with the date of sailing, and if you find this date, everything will be clear?

He hurriedly flipped through the card, but saw that on the back of the card was a simple map, which indicated the route of the cruise ship's voyage. Hu Kai took out his cruise card and compared it, it was exactly the same, and the itinerary of the two cards was exactly the same!

At the same time, he also found the exact date from the upper right corner, and after putting the two cards together, the date marked on them turned out to be exactly the same!

No way?

What's hairy?

In an instant, Hu Kai felt cold all over, and the strangeness of things was far beyond his imagination.

"Mr. Hu, what's wrong? What's that? ”

Seeing Hu Kai stunned, Tingting couldn't bear it anymore and asked again.

Hu Kai shook his head, and only then did he wake up from his trance.

Well, well!

Since you can't figure it out, don't think about it yet, after all, it's still unknown whether you have a life to live or not.

So, Hu Kai took off the card and put it in his pocket, and then climbed a few steps hard, and then climbed over the garbage mountain and returned to the ground.

In front of the garbage heap, a square space suddenly appeared, like an old-fashioned and old building entrance.

In addition to the staircase where they came, the entrance of the stairs also connects to three other directions. The left-hand side is also blocked by a mountain of debris, and only the front and right-hand sides can lead to the outside corridor.

The dim light was shining from the corridor outside.

Seeing that there was no abnormality, Yang Lele and Tingting also climbed into the entrance of the building one after another.

Who knows, as soon as I entered the damp and stuffy corridor, a particularly fishy and pungent airflow suddenly came.

The smell seemed to have fallen into a salted fish tank in summer, the fishy smell was pungent, and the stench was stinking, which seemed to be several times more powerful than the sum of all the odors in the passage just now, and it was so smoky that people's brains hurt!

Tingting and Yang Lele hurriedly covered their mouths and noses, not daring to breathe, and their stomachs began to churn violently. If it weren't for the fact that they were in prison at the moment, I'm afraid they would all have to open their mouths and vomit on the spot.

Seeing this, Hu Kai hurriedly pulled out a scarf full of stains from the mass of garbage. After gently tearing it open, it covered the two ladies over their mouths and noses and served as temporary masks.

The scarf didn't smell much better, but it was noticeably better than the disgusting stench that filled it.

After wearing a mask, the second daughter was finally able to breathe a little.

Just when Hu Kai was looking for a scarf just now, he found a treasure from the garbage again. Unexpectedly, in a suitcase with only half a pull left, there was actually a can - insecticide!

Although the words on the bottle are all written in Korean, Hu Kai can still recognize through the small icons on it that it is a can of insecticide!

If you haven't run out of pesticides, you should be able to use them for self-defense. Even if you can't prevent yourself, it's good to protect yourself from some mosquitoes and flies.

Thinking of this, Hu Kai hurriedly squatted down and rummaged through the half-pulled schoolbag, wanting to get the insecticide in his hand as soon as possible. Who knows, in such a moment, from the corridor outside the corridor, there was a sudden sound!
