The bright headlights pierced the darkness, and the sound of the train rolling over the rails came from far to near.

Du Kang, who was waiting on horseback in front of a simple station, saw a huge black metal object coming from a dark tunnel.

The front of the car made of unknown black metal is three feet high and can barely be accommodated by the tall tunnel; the headlights above illuminate the road ahead; there is a scarred cone-shaped bumper installed in front of the front of the car, which is covered with black or red grease.

It is a liquid-like liquid; the metal steam pipes with complex structures prevent the constant-temperature water from leaking out and can only circulate inside the train body; the huge steel wheels as tall as one person are connected together by connecting rods to jointly push the vehicle forward.

The heavy, tall, and long train made the rails beneath it make an overwhelming metallic groaning sound. Coupled with the extra layer of dark steel plate installed on the train, the entire train looked like a black demonic dragon crawling underground.

No matter in his past or present life, this was the first time for Du Kang to see such a huge train.

"Jiu Bai, every train on the underground track seems to be run independently by an individual. This train will pass by the Gear Tribe, so safety should be guaranteed, right?"

The surface world of Xingtian Dongtian is ruled by Xingtian City, but the dark and vast underground track is a mixed bag. Not only does it cover the entire world, it is also a complex underground world with more than one layer.

It is rumored that the underground of Xingtian City, where the underground tracks are the most complex, has hundreds of criss-crossing tunnels. Through the complex connections between them, large or small tunnels are constantly being newly dug and blocked. The residents in them are even

Able to avoid regular searches and seizures by Xingtianlishi of the same level.

The losers of the ground tribes, the native monsters in the metal earth, the traitors of Xingtian City, the wilderness hunters who make money with guns, the weak races who cannot survive on the ground...

Nearly half of the creatures in Xingtian Cave live underground.

As the main means of transportation underground, trains mostly need to be run by powerful individuals or groups in order to survive in this dangerous and chaotic zone.

"Jiu Bai knows a little bit about it. This car is called the Black Armored Fire Dragon. It is controlled and run by a gang called the Brotherhood. They have a pretty good relationship with the Gear Tribe. They are friends who have cooperated several times, so they are allowed.

Passing near the tribe."

Jiu Bai pressed her body against Du Kang's, and the contact between the soft liquid metal and the hard steel made her fire jump happily. This was a phenomenon that only occurred when the body and mind were happy.

"Are they friends? I think one day I will become a friend of the Gear Tribe."

Du Kang's steel face reflected the lights of the train in the distance, looking cold and hard, but in Jiu Bai's eyes, there was a different kind of gentleness in this chiselled face.

"Of course. A good person like Brother Du Kang will definitely become a friend of the tribe and a better friend of Jiu Bai."

squeak--

There was a harsh friction sound. Maybe the driver saw someone waiting here. It was still far away from the platform, so the black-armored fire dragon stepped on the brakes.

Under the huge dead weight, the rails and wheels rubbed against each other, sparking sparks, and the car started to stop with difficulty.

First came the thickest front of the car, and then the slightly thinner carriages. In the gaps specially left in the heavy steel plates of the car body, Du Kang saw pairs of eyes of different colors and shapes.

It is worth mentioning that each carriage has three levels of observation gaps, which means that this train has three levels of seating.

It wasn't until they taxied to the last carriage that the black-armored fire dragon reluctantly stopped in front of Du Kang.

Facing such a giant thing, Du Kang subconsciously swept it away with his spiritual consciousness.

[Name]: Black Armored Fire Dragon/Steam Train (Large)

Grade: upper and lower grade

characteristic:

Steam Turbine (Large): Continuously provides powerful power that is not inferior to that of a Great Demon Peak Demon Dragon, and can drag hundreds of times the weight of cargo forward on the track.

Black-armored carriages: The fifty carriages are all forged from black frost iron. They have a defensive power that is difficult to break through for Xingtian weapons below mid-level. There are hidden machine guns on the sides and top of each carriage.

Fusion transformation: The front of the car can be used as a power source to combine with the members of the Brotherhood, allowing them to explode with attack power beyond their own level.

"Can they still be combined? Xingtian Dongtian always brings me surprises."

Wow——

Amidst the smooth sound of the rails, the thick black metal door of the last carriage opened, spilling out a bright light.

"I'm sorry, the driver's eyesight was bad, he almost didn't see you, and he braked a little late.

If you happen to be bringing horses and pets, the last carriage is a carriage with no height limit, so you can take this one.

Two medium-sized passengers, one medium-large-sized mount, and one small pet are required to pay eight pounds and four taels of Raging Flame Crystals or equivalent currency as a head fee for boarding.

If the destination is far away, please prepare the corresponding ticket replacement fee in advance, and the flight attendant will come to collect it soon."

There was a lazy sound from a speaker in the car door, but it was cut off without repeating it a second time.

The two passengers, one mount, and one pet mentioned by the other party should refer to Du Kang, Jiu Bai, Mengxiang and Yang Liu.

Although he didn't know the specific charging standards, Du Kang harvested a lot of angry fire crystals after killing Copper, Iron and Tin, and after giving some to Jiu Bai, it was still enough to pay the fare, so he didn't care about these small things.

A person's attitude towards money is always directly proportional to the amount of wealth he possesses. Du Kang was also extremely stingy when he was a pauper, but since he became rich, he has naturally become generous with his dealings.

Under the gaze of others, Nightmare did not use the ability to travel through dreams, but walked honestly into the tall carriage.

This place is like an empty metal box, with several huge machines sitting on the ground, looking at Du Kang, the new passenger, with vigilance in their eyes.

The underground track can exist for a long time and naturally has a corresponding order. If people living in it want to live a long life, the first thing they have to do is abide by it.

This chapter is not over, please click on the next page to continue reading! One of the rules for train passengers: Do not talk to strangers casually.

Du Kang did not dismount, but stood steadily at the end of the carriage, waiting for the conductor to arrive.

The black frost iron steel door behind him closed automatically, and with the dull sound of wheels rolling over the rails, the black-armored fire dragon restarted.

The train was traveling in an oppressive dark tunnel, and outside the window, which was only the size of a slit, there were patches of rapidly receding space, and bits of light illuminated by radioactive stones.

Du Kang looked at these in a daze.

"How long does it take to get to the Gear Tribe from here?"

Du Kang's voice was very soft, almost completely submerged in the deafening roar of the train, but Jiu Bai still heard it.

"It depends on which route the Black Armored Fire Dragon takes this time. The underground rail lines are extremely complicated. Even drivers who often take these lines often get lost due to the destruction and changes of the lines.

So the time you take the train every time is uncertain. At the fastest time, it takes three days, and at the slowest time, it even takes half a month."

Wandering through the maze-like underground tunnels, embarking on a journey that you don’t know when it will end, is another unexpected local style.

"It sounds very interesting. I kind of like this journey."

Du Kang glanced at Jiu Bai in his arms again, his scarlet copper fire eyes flashing with moving luster, and he quickly added.

"Especially when I can stay with Jiu Bai, no matter how boring the journey is, it is always happy."

"Jiu Bai feels the same way."

Jiu Bai felt that her fire was surging like never before, and her unprecedented hunger made her want to embrace Du Kang's fire and let the two blend together.

Wow——

At this moment, the front door of the carriage was pushed open, and a mechanical mouse with a swinging mechanical tail and two wheels on its hind legs came in and headed straight for Dukang.

"Passengers, where will you get off? Are you ready with your ticket money? Poor people without money will be thrown off the bus."

The small black iron body, two large shiny steel teeth, and red eyes make this mouse look extremely cunning.

[Name]: Gangya/Xingtian Bloodline·Black Iron·Mechanical Rat

Level: Great Demon (2/3)

Skill: Xingtian Fire (Fifth Level)

Data manipulation (five levels)

Black Iron Body (Fourth Level)

Electromagnetic Heart (Fourth Level)

Crystal battery (triple)

Transformation conditions: Gather the body parts required for the next level of transformation and perform the fire transformation ceremony.

Divine Weapon: Black Armored Fire Dragon has partial attack rights.

The Mechanical Rat is a fifth-level demon, but it has three body parts that are lower than level five. It seems that the promotion configuration of the descendants of Xingtian is not particularly strict. As long as the core components meet the standards, you can try to advance.

The body parts of the Xingtian Lux I met were all top-notch ones that I could control. This should be due to Xingtian City’s deep wealth. In comparison, the lives of these underground orbit residents were a bit hard.

Du Kang used his spiritual consciousness to scan the other machines in the carriage. As expected, they were all with low-level body parts. Haha.

Du Kang asked directly. "We want to go to the Gear Tribe. How much does it cost in total?"

"The Gear Tribe..." A string of data flashed across the eyes of the mechanical mouse. He immediately spread his hands and said, "There are a total of sixteen kilograms and two taels of Raging Fire Crystals. Please pay."

"If I want to change to a better carriage, how much will it cost?"

Du Kang put a large piece of Raging Fire Crystal into the hand of the mechanical mouse and continued to ask.

"Guest, your horse is too big. There is not enough room in the front carriage to accommodate it."

The mechanical mouse had a look of embarrassment on his face. Although he also wanted to make this money, there was no place if he didn't have a place.

"What if this is the case!"

Du Kang slapped the nightmare on the neck, and it immediately turned into a phantom and disappeared. It actually sneaked into Du Kang's dream.

"I was mistaken just now. This turned out to be a nightmare. Distinguished passengers, please come to the front with me."

The mechanical mouse had a look of surprise on its mimic mouse face, apparently realizing that the nightmare was not a descendant of Xingtian, and turned its wheels and walked toward the front door of the carriage.

The exit of Xingtian Cave is located in the dreamland. It is not surprising that someone can recognize the nightmare. Du Kang followed closely behind the mechanical mouse and led Jiubai and Yang Liu into the carriages in front.
