Mars, Prospector 1 Cave.

At this time, the surface was windy and sandy, and the passage for the drill truck to drill was quickly blocked by the gravel.

Four or five Martians armed with torches are ordering a group of black-haired apes to carry rocks and seal the holes.

Their torches are made from an underground vine plant whose skin has a lot of oil and is very easy to burn.

In the light of the fire, the cave was surrounded by water vapor, and the roaring river crossed east and west, flowing into the largest river in the area: the Kasar River.

The name Casal, which means 'forever' in the local culture, is also known as the underground kingdom that controls this world.

The Casal Empire is one of the underground kingdoms of Mars, with 420,000 square kilometers of land and three rivers, and a population of more than one million.

Their current civilization, somewhat similar to that of Europe in the 17th and 18th centuries, had already invented the steam engine.

In the use of the steam engine, the Casals were more proficient than the earthlings.

In addition to Casal, there are more than ten other tribes in the Martian underworld, the most powerful of which are the Rock Empire and the Nia Empire.

The Rock Empire controls 700,000 underground territories, and Nia controls 600,000 territories, and the scientific and technological strength of the two countries is close.

Originally, Mars had a period of technological civilization comparable to that of human society.

But as Yang Ye guessed, a magnetic pole flip destroyed the Martian civilization.

Let the Martian ancestors have to live in the underworld.

Over the next few billion years, the underground Martians fought hundreds of millions of wars. From the age of firearms to the current era of cold weapons, civilization was once extinct.

It wasn't until 45 million years ago that the appearance of the Casal people rekindled the Martian civilization.

The Casal people, the ancient ancestors of the present-day Casal people, are very close to the 'modern humans' of the fourth stage of the earth, and are good at creating zào objects with their hands.

After 1 million years of development, Casal unified the Martian underground world and divided dozens of small countries, somewhat similar to the 'Zhou Tianzi Dynasty' in ancient China.

When technology has developed to a certain extent. A voice appeared in the kingdom: go to the earthly world.

According to historical remnants of the literature. The people of Casal know that Mars was originally a warm pure land with blue sky and white clouds, and because of the punishment of God, it became the current desert planet.

In order to change Mars back to its original form, the Kingdom of Casal also wanted to use technology to change the climate and environment.

But the cruel climate makes it impossible for plants to survive at all.

No plant can survive in minus 60 environments. Once the water reaches the surface, it becomes as hard as a stone. Within 5 seconds of a person's appearance, it becomes a sculpture.

Two hundred years later. Casal scientists discovered the Earth.

The blue earth in their eyes, like the mythical Mars, they could not describe the feeling at that time.

Thereupon. Then the Kasar scientist said, "We're going to that planet!" ”

This tiyì gained the support of the rulers, who tried their best to reach the earth.

So after a referendum, they decided to use the forbidden technology 'gunpowder' in civilization!

Hundreds of millions of baptisms of war have made Martians afraid of such things as gunpowder.

It can cause the underground world to collapse and crack the ground, and since the Middle Ages, the Martians have unified the method of destroying the development of gunpowder, and anyone who makes it will be killed as a 'demon attendant'.

The disappearance of gunpowder did allow Mars to multiply.

Just like the Zuò rockets made by the earthlings, the earliest 'spaceship' of the Casals was a powder keg containing potassium nitrate, charcoal, and sulfur, which could be launched, but the explosion caused by mistake was also very amazing.

In the midst of one failure after another, people began to think that 'Earth' was a demon that lured them to death, and that it was impossible to go there.

In the decades that followed, the king put an end to the 'Migration to Earth' program.

As soon as his son ascended the throne, the project was restarted, but this time instead of gunpowder, they tried to use electric engines.

By the time the young king turned into a gray-haired old man, a shuttle-shaped flying machine was built.

In order to send the aircraft to the surface, the king sent hundreds of thousands of people to dig a tunnel more than 1,600 kilometers long.

The exit of the tunnel can still be seen on the satellite map of Guò American Explorer.

In June 2010, in a middle school classroom in California, USA, teacher Dennis and students jointly discovered the entrance to the tunnel, which was then mistaken for a natural cave.

They don't know that the 45 pairs of Martians are leaving Mars through the guò tunnel and arriving at the Blue Star World (Earth).

When these Martians came, the Earth was in the middle of the Tertiary period.

Reptiles gradually became extinct, and mammals, birds, bony fish, and insects became the new rulers of the planet.

Seeing this flowery world, the Martians were extremely excited, and they waited for their companions to arrive, and first to breed on Earth and domesticate the local mammals.

But then they didn't wait for the Martian army of immigrants, but ushered in the flip of the Earth's magnetic poles!

Lost magnetic field protection guide zhì a large number of animals extinct.

They had to flee underground again with some of the animals.

10 million years later, our ancestors mutated in the Martian virus and cosmic radiation, evolving from lower primates, to higher primates, and then Australopithecus.

During this period, the underground world of Mars was already a different scene, and the former kingdom was long gone.

Just as the first Martians left the underworld, the 'lords' of the king's fiefdoms, fearing that the demons would take revenge on them, killed the king and burned a piece of technology.

Of course, killing the king is not the culprit that destroys a race, and the destruction of the ancient Casal kingdom is the change of the underground microclimate.

Over the next 30 million years, the surviving Martians slowly evolved in battle with mutated creatures and gradually restored civilization.

The current Martians are far stronger than ordinary humans.

The average height of modern Martians is 2.5 meters and their weight is 300 kilograms. It is basically close to the gorillas on Earth.

They can lift a 500-kilogram object with one hand, just as easily as carrying a 10-kilogram bucket of cooking oil.

……

Prospector's Cave 1, where the slaves are still working.

These slaves were intelligently retarded apes, close relatives of the Martians, similar to humans and chimpanzees and monkeys.

However, Martian apes can be tamed, and they accept the rule of the Martians.

"My lord, could it be that the Iron Demon was made in the Rock Country?"

An armored guard carries the head of Prospector 1.

"No, they can't make anything like that, don't you see that the Iron Demon doesn't have a steam furnace on his body?"

Orin, the Martian leader, thought for a moment, looked at the hole that was being filled, and said, "That iron bug (drill cart) is from hell (surface). This Iron Demon must have come from there, too! ”

"This is a very bad sign. We are going to do our best to sue your majesty and the high priest. ”

"Yes, my lord, your wisdom is brighter than fluorite." The guard praised.

After 1 Earth hour, the entrance to the cave was completely sealed, and the leader marked them down the river. Take a small boat ride to the end of the Kasar River, 400 kilometers away.

Walk through underground caves. See a vast and endless underground plain.

The plains are dotted with stars. Those are the fires in the village courtyard, and a magnificent white rock complex can be seen directly in front of them.

The castle was more than 200 meters high and was carved out along the cliff. One of the king's most powerful and wealthy people lived there, and it was the Imperial City of Casal.

Orin does not belong here, he is the lord of another city, and he was recently summoned by His Majesty the Emperor, and specially brought his guards and slaves to the imperial capital to face the saint.

But he didn't expect it: on the way here, he encountered iron bugs that came out of the rocks, and there was an iron demon similar to them among the bugs!

Orin is going to give the demon corpse to the king first, and maybe he can make a good weapon or two.

……

Step inside the Great Palace.

I saw that the place was full of light, and the rocks on the walls and dome shimmered with golden brilliance.

These rocks contain a lot of 'phosphorus', and together with the crystals on the surface and the torches in the palace, this place is as beautiful as a temple.

"Honorable Lord of Casal, your courtier Orin has been ordered to come and bring you a gift." Orin's voice echoed through the hall.

"It's been a great job all the way, Orin."

The king is a 70-year-old man who has ruled the kingdom for more than 50 years and will rule for the next 50 years.

However, after the nuclear bomb of the earth arrived, it was difficult to say.

"What is this? He looked like a head. ”

"Your Majesty, this is a part of the demon's body, and the courtier has other bodies to present."

As he spoke, Orin put on his chest armor and motioned for the slaves to send the body and arms of Prospector 1 into the main hall.

The surrounding royal family and nobles came forward to watch the excitement, and the king asked:

"What is he? Why is the body made of iron? Where did you get it from? ”

"Back to Your Majesty, the courtier was found on the Kasar River!"

"When Orin heard the noise, he led his servants to hide in the rock, and sure enough, he found a pointed iron worm coming out of the rock......"

"After a while, the Iron Demon crawls out of the belly of the iron worm and drinks water (to collect samples) by the river, and his eyes emit blinding light (laser scanning......"

"Your Majesty, please see, there is no flesh in his skull, it is all steel."

Orin ripped off Prospector 1's cheek with his bare hands, and the sophisticated machinery came into view!

"God, who made him! Is he really from above? The crowd exclaimed.

The king grabbed his head and pondered for a moment, "You are too reckless Orin, why don't you ask him what he meant?" ”

"Majesty ......" Orin didn't know how to answer, he also made a move because he was frightened.

"Are you sure he's from the Overworld?" The king asked.

"Yes!"

Orin said firmly: "After the courtiers and servants killed him, the steel worm returned to Hell, and we all saw the light of Hell. (Skylight)"

"Has Portata's prophecy come true......

The king's face changed instantly, and he pondered for a moment and ordered the guards, "Go and ask the high priest to come." ”
