Although abyssal rock steel is rare in the main plane, it is only relative, and the price of ordinary magic metal in the abyss is about the same, and it is only after it is smuggled into the main plane through the plane merchant that the price will be so expensive, after all, things are still expensive.

There are many other phenomena of this phenomenon in the main plane.

Some things that are worthless and rotten in other planes are priceless in the main plane, and it is only when they drove the floating islands to conquer one plane after another and suppressed the arcane empire layer by layer of abysses that they were able to collect special materials in each plane and reduce the transportation price of materials to the limit.

Deloris knocked on the steel barrier mixed with abyssal rock steel, with the stable characteristics of abyssal rock steel, the tunnel wall of this subway has not been corroded until now, and it is even like when it first left the factory, but the strength has decreased slightly after the baptism of time.

The people of the Plague Sect were beating around the steel barrier, and they had no good way to deal with this strong and abnormal steel barrier, so they could only use high-strength diamond drill bits to break through little by little.

However, for the gods, the steel barrier of this strength could not stop them at all, let alone the goddess of calamity and plague with powerful divine powers.

I saw that Delores's palm was lightly imprinted on the steel barrier, and then the powerful divine power was instilled into it, canceling out the effect of the abyssal rock steel, making the steel barrier of several meters around it turn back into ordinary steel, and even because of the calamity divine power, the strength of the steel decreased again.

"Poof!"

Immediately after that, the steel barrier was like cream, and it was easily cut into Delores's palm, and then her hands pulled up and down, and a huge crack suddenly appeared on the steel barrier.

Deloris acted so easily, as if it was not a few meters of steel that was torn, but a thin sheet of rice paper.

"The alarm didn't go off? It doesn't seem that all the equipment is still running. Deloris muttered to herself.

Generally speaking, after the steel barrier is destroyed, it will definitely trigger the internal alarm equipment, but this time it has torn out a hole several meters large, and the alarm equipment still has not the slightest movement, obviously losing its due role under the erosion of the years.

The Plague Cult swooped through the hole and went inside the subway to investigate, but nothing could be seen except in the pitch black.

Deloris followed into the subway tunnel, and immediately noticed the abnormal situation inside, the already very turbid air, there was a very strong negative energy, which made everyone in the plague sect feel very uncomfortable.

Only places where a large number of dead creatures, large battlefields, the underworld, etc., will have such a strong negative energy, which is the best place to breed the undead, and it is also an ideal habitat for monsters that feed on all kinds of negative energy.

"Even if the ventilation equipment in the tunnel is damaged, it is impossible to have such a strong negative energy." Melissa frowned and said in a deep voice: "There is a high probability that there are undead creatures here, and there is still the breath of the undead in the air, so we need to be prepared to meet the enemy." ”

The other members of the Plague Sect collectively nodded when they heard this, they also sensed the undead aura, but it was mixed with negative energy, and it was difficult for people to detect.

Deloris dispelled the negative energy that was comparable to poison gas for life, and then cast a light magic spell to illuminate the surrounding environment, and found that there were four subway tracks in each direction laid on the ground, and the surface of the tracks was not dusty, and even shiny, which is a proof that people often use it.

"It's strange that even if the subway were to follow the program itself, it couldn't have been so frequent." Deloris looked at the railroad tracks on the ground and said to herself: "If you run the subway at this frequency, it is impossible to have the energy left until now, unless someone restarts these magic subways, it is really unreasonable." ”

There are many Arcane Empire relics still in operation in the main plane, but these relics usually turn off most of their functions to reduce the amount of energy they store, and it is impossible to use them so often.

According to the energy storage technology of the Arcane Empire back then, such frequent operation of the magic subway could only last for hundreds of years at most, and at least thousands of years have passed since the destruction of the Arcane Empire, and even the arcane engine of the Floating Island should be shut down.

"Woooooo

The sound of the subway running at high speed suddenly reached Delores's ears.

The sound traveled far through the narrow space of the tunnel, and then the people of the Plague Sect also heard the sound, and immediately formed a battle formation, ready to see who was running the subway.

In the distance, a little blue light appeared in the dark tunnel, and then it quickly began to amplify, accompanied by a loud roar.

When the blue point of light got closer, its true face was finally revealed.

A huge train similar to the subway was flying on the tracks with blue flames, but this flame did not bring high temperatures, but made people's backs cold, and the cold hairs on their bodies couldn't help but stand up, giving people a trembling aura that reached the depths of their souls.

"Soul Flame! This is a ghost train controlled by a ghostly spirit, similar to a ghost ship at sea. The people of the Plague Sect said with solemn faces.

With such a huge ghost train, ordinary people can't stop it at all, if you insist on going up to block it, it's like using a mantis arm as a car, and after being hit and killed, the soul will be sucked into the ghost train and become the fuel to drive it.

Deloris looked at the rapidly approaching ghost train, frowned, and said, "Could this be a good thing done by those people in the realm of the undead?" Is this what they are attacking the Arathi Heights this time for? ”

"No, there is an abyssal stench on this ghost train, something made by those demons."

The ghost train is wrapped in a layer of negative energy that forms a substance, constantly absorbing the negative energy along the way to strengthen itself, and continuously supplying the high-speed operation of the train, even with a full car of goods, it has not slowed down, and no one on the scene knows where the ghost train is going.

"My lord! Shall we take this ghost train with our hands? Melissa said eagerly.

This is a very rare ghost train, and there are not even a few in the realm of the dead, so you can't let it go if you encounter it here.

Deloris nodded, then replied, "Stop this ghost train, but to see what those demons who can only hide in the shadows are paying attention to this time." ”
