Time in the underworld is synchronized with that on the ground.

Although in Blackwater City, it is impossible to see the sun and the moon at all.

However, the white mushrooms that grow on the surface of the stone pillars and stone walls emit bright light during the day and fall silent at night, creating a natural phenomenon of day and night.

To the point where all the white glow mushrooms fell asleep, this bustling dungeon was lit up with sporadic lights.

From a distance, there is a different kind of beauty.

Gao Jing sat on the balcony on the third floor of the villa, drinking and enjoying the night view of Blackwater City.

The mood is extraordinarily relaxed.

Meow~

Jiuqi got out from under the chaise longue and nimbly jumped onto Gao Jing's body, rubbing his chin affectionately.

Gao Jing smiled slightly.

He touched the little one's head, slowly closed his eyes, and cleared all the distractions out of his mind.

Visualize the sacred mountain according to the method in the mountain alchemy.

In the sea of knowledge, the towering Kunlun suddenly appeared!

Xiao Jiu, who was curled up in Gao Jing's arms, felt something and glanced at his master suspiciously.

It tilted its head and silently jumped back to the ground.

The long night has just begun.

Early the next morning, before the bell rang seven, Gao Jing came to the Black Water Society of the Yuancheng Alliance.

He arrived early, and Quibao and the rest of his teammates hadn't shown up yet.

Gao Jing entered the hall.

After some inquiry, he learned that the wooden plaque he had obtained from the black-robed wizard yesterday was called the homeowner's card, and as the name suggests, it was the identity card of the houseowner.

The homeowner's card is a low-level witchcraft, and one card corresponds to a house in the upper city.

If you don't have a landlord's card, even if you can sneak into the upper town without the checkpoints and patrols, don't want to sneak into the villa.

Because this will inevitably trigger the totem circle arranged inside, triggering an alarm to attract patrol soldiers.

Of course, a family may have several or even a dozen people, as well as maids and maids, and so on.

Therefore, the landlord's card can be used to produce replicant cards and servant cards for family members and servants to carry in and out of the city and the house.

But this is the only part of the homeowner's card, and it will be very troublesome if you lose it.

This guarantees the safety of the upper town to a great extent.

Homeowner cards can be bought and sold and traded freely.

But if you snatch or pick up someone else's homeowner's card, it doesn't mean that you are the owner of the house.

Unless there is no grievance!

And the villa where Gao Jing lived last night, the original owner was lying in the storage space, and there was no possibility of complaining.

So in theory.

Gao Jing, who holds the owner's card, is fully able to take this valuable house for himself!

It's just not entirely cost-free.

Although the house in Shangcheng District is a freehold property, it needs to pay 5% of the land tax on time every year, and the tax amount is calculated according to the market value, in addition to the maintenance fee of the totem array, the urban infrastructure fee, the guard fee, the cleaning fee, the water fee...

All kinds of taxes and fees add up, which is not a small amount!

If the homeowner is not able to pay the taxes on time, even if it is only a copper coin.

Then his house will be immediately repossessed by the deacon hall, the owner's card will be invalidated, and it will be auctioned again!

Gao Jing felt that he had seen this kind of routine somewhere.

He inquired and found that the taxes and fees for his house had been paid this year, and the next payment would be at the beginning of next year.

It's not easy to live underground!

Bell!

The bell tower in the city rang with the ringing of a bronze bell seven times in a row.

The whole city is fully awakened.

At this time, Gao Jing met with Kuibao and the others at the door of the hall.

Kui Bao was crisp and neat: "Let's go!"

Under his leadership, Gao Jing and the other four team members arrived at a building next to the club.

Then follow the long staircase deep into the ground.

Because there is also white glow mushroom lighting inside, the light is bright.

But the further down Gao Jing went, the more surprised he became.

When he reached the finish line, he couldn't believe his eyes!

"It's the way of the earth. ”

Kui Bao noticed Gao Jing's expression and explained with a smile: "The underground rail car will come over later, and we can save a lot of time by taking a ride to Senluo Ruins City." ”

Gao Jing nodded.

It's just that his heart is far from being as calm as it seems.

The so-called pavement with railroad tracks in front of you is clearly a subway, and it is double-tracked!

On the platform, there are already many adventurers like Kuibao and others waiting.

Although compared to the subway in the Overworld, the tunnels here are very primitive and rudimentary.

But Gao Jing really didn't expect that there was already a primary rail transit system under the big world.

What opened his eyes even more was yet to come.

After about four or five minutes, a long train of ground rail cars drove over.

Docked in front of the platform!

The front of the locomotive, the carriages, the wheels, and the upper and lower doors, this so-called underground rail car, is not much different from the train that Gao Jing is familiar with in terms of structure, it is very similar to the old green car.

It's just that the color of the body is black and gray, the compartment has open grid windows and no glass, and there are five cars with the nose.

What made him speechless the most was that there was still white steam on the front of the car!

Is it still a coal-burning steam engine?

Gao Jing didn't smell the soot.

"Get in the car!"

Kuibao jumped on the ground rail car first, urging Gao Jing: "Don't be stunned." ”

Gao Jing came back to his senses and hurriedly followed to get into the car.

The inside of the carriage is quite spacious, and there are rows of seats.

But no one.

The first passengers who just came up were the first passengers.

Kuibao asked the team members to sit together and said, "It will take about ten minutes to get to Senluo Ruins City, everyone will rest first, and if there is anything you don't understand, just ask me." ”

The one-eyed warrior's gaze looked at Gao Jing, and the meaning in his eyes was obviously that Gao Jing was a rookie.

And Gao Jing is indeed a rookie adventurer.

He never doesn't know how to pretend to understand, and he doesn't like to slap a swollen face and become fat.

Out of a strong curiosity about the ground rail car, Gao Jing asked Kuibao a lot of related questions.

In fact, the full name of the ground rail car is called the psionic ground rail car, and its locomotive is a large witch weapon, which is driven by psionic energy to drag the carriage behind it to transport passengers or goods.

The ground rail car appeared thousands of years ago, and it is the most important means of transportation connecting different Yuan Cities.

The current tunnels have connected thousands of Abyssal Cities!

The tunnels in Blackwater City were dug ten years ago, mainly connecting Wuzhi, Iron Furnace and Shahu Yuancheng.

And the Senluo Ruins City that the Kuibao team is going to go to was accidentally discovered by Iron Furnace Abyss City when they opened up a new tunnel, and then released a large-scale exploration mission in the Abyss Alliance.

This quest is rewarding and competitive, with many teams of adventurers participating.

As he spoke, more and more people came to the car, and soon the entire train was packed!

The last adventurers to come up didn't have seats.

The first one is sent.
