The natives have good ontological abilities. Denis quickly returned to their city.

At the gates, Denis shouted, "There is a powerful demon attacking, and Captain Tonav has died." Gather the people in the wilderness back to the city, close the gates, and prepare for battle. ”

After shouting, Denis crawled to the temple in the center of the city.

Outside the temple, Denis fell to his knees and shouted, "Denis, please see the High Priest." High priest, there is an enemy attack, so prepare quickly. ”

As Denis shouted, the door to the temple burst open, and a tall, Western-looking old man appeared in front of Denis with a group of people.

The old man with the scepter was Hernez, the archpriest of the natives of the underworld.

Hernez looked at Denis and said majestically, "Denis, you tell the matter from the beginning. ”

Denis nodded, "Okay, High Priest." Just now, when Tonav led our Fourth Patrol Team to the exit of the world, he encountered a group of strange people. Leading the way was a medium-sized man with black hair, black eyes, and yellow skin, with a dozen people wearing strange metal armor and armed with strange weapons. We fought with them, and none of our feathered arrows could leave a mark on their armor. Tonav and the others were all beaten, and only I fled back to report the news, asking the tribesmen to prepare early. High Priest, I'm on the verge of escape, and I'm damned!" said Denis, pulling out a dagger and wiping it towards his neck.

With a 'clank', the high priest struck off the dagger in Deni's hand with his scepter and said, "Deni, you have returned to report the news meritorious, and there is no capital crime. Now, you hurry down and gather your men and go up to the city wall to guard it!"

"Yes, High Priest. Denis hurriedly stepped back.

Hernets then ordered his elders to ring the alarm of the enemy's attack, telling everyone to put down everything they had and go to the city wall to defend themselves.

Looking at the chaos in the city, the high priest sighed faintly, he didn't know if his people would be able to escape the catastrophe this time. Perhaps today is the last end of the Orions left on Mars.

Over the long years, these thousands of Orions, who were originally assigned to mine in the underground world, have grown to nearly 100,000 now. However, due to the lack of energy, they have lost the ability to develop science and technology, and gradually degenerate into indigenous people.

Among these people, only the high priests of each generation are qualified to use a pittance of resources to learn the rudimentary sciences and pass on the true history.

Historically, quantum computers placed in the underworld have been able to connect with old family members. Through quantum computers, the high priests of the past generations knew that the people of his hometown had launched three counterattacks against this small star system in order to obtain precious fire crystals, but unfortunately they were all repelled by the overwhelming flying saucers.

The Orion Galaxy is 2,500 light-years away from the solar system, and three unsuccessful expeditions have caused the old family to lose their enthusiasm for fire crystal. At the moment when the energy of the quantum computer is finally exhausted, the old family tells them that they must hide in the underground world, and must not appear on the surface for the other party to discover.

The old family told them not to give up the mining of fire crystal, saying that one day, the army of Orion would drive to the solar system to save them.

After the quantum computer was shut down, the Orions underneath were completely cut off from all outside news. They are stuck in an endless wait.

But today, I waited for the news that someone had invaded the underworld.

The High Priest thought to himself: If nothing else, it must be the descendants of the Niztecs who discovered the entrance to the underground world and entered it.

With the High Priest's limited scientific and technological knowledge, he also knew that most of the metal full-body armor worn by the group of people in Deni's mouth was the mecha mentioned in the history books.

The description of the power of the mecha, even if it is only half of what is said in the book, is enough to annihilate the entire race.

Now, the High Priest had no choice but to wait for fate's verdict on their group of orphans.

Lin Yuan's team led a dozen incapacitated Orions to a distance of more than a hundred meters outside the city walls.

In the eyes of the crowd, the height of the wall made of rocks in front of them was about 20 meters. The length of the wall on this side was about two kilometers, and the walls were full of tall Orions with strange cold weapons, shouting and cursing at everyone.

Lin Yuan exhaled and said, "Which of you is the leader, stand up and speak." "He speaks the language of the Orionians. The powerful spiritual power allowed Lin Yuan to master this language in a short period of time.

Armed with a scepter, Hernez stood in the gatehouse above the city gate, guarded by a group of men.

At this time, he stepped forward and said loudly, "I am High Priest Hernetz, the supreme leader of Mining City. Your Excellency, where do you come from, what are you doing here, and why are you hurting my people?"

Lin Yuan laughed and said, "High Priest Hernets, right? Since you are the leader of this group of people, I think your history must have been passed down to you. You've probably guessed where we came from. I'm not playing with you, we are indeed descendants of the Niztecs who trapped you underground tens of thousands of years ago. Today, we are here to conquer you. Now you have two choices, two destinies. The first is unconditional surrender and can live. The second is to resist desperately and exterminate the clan!"

The High Priest's face suddenly turned bitter.

The tens of thousands of Orions on the city walls clamored and raised their weapons and shouted incessantly, asking the high priest for battle, and they wanted to rush out and kill the enemy.

The vast majority of Orions have degenerated into natives, unaware of the horrors of technological weapons. In their opinion, no matter how powerful Lin Yuan and the others were, they were only a dozen people.

In this underground world, it is not without beasts. But no matter how strong the beast was, it fell under their siege.

Lin Yuan smiled slightly and gestured to the mecha warrior next to him. The mechwarrior understood, and raised his mechanical arm, and a small cannon muzzle appeared on the arm.

The fighter aimed the muzzle of the gun at a mountain peak in the distance, excited.

A miserable white beam of light struck the lower part of the mountain in an instant.

'Boom', the mountain peaks collapsed, and countless rocks rolled down from the mountain, making a huge crashing sound.

The people on the city wall were taken aback, and looked at the mecha warrior who fired the cannon suspiciously, wondering if he had done something.

Having degenerated into natives, they never believed that artificial creations could have such great power.

The mecha warrior suddenly volleyed into the air, hovered at a height of 100 meters, and fired several shots at the ground not far away.

In the rumbling, the sand flew away.

After the smoke and dust subsided, several large pits with a radius of two or three meters and a bottomless depth appeared on the ground.

The natives on the city walls were shocked to believe that the weapons in the hands of the enemy were indeed unimaginably powerful.

The Mechwarrior floated in the air, looking down at the natives on the city walls, and raised his weapon at them.

The natives screamed in shock and fled in all directions, trying to avoid the front of the mechmen.

At this time, more than a dozen mecha warriors rose into the air, lined up in the sky above the front of the city wall, opened the cannon ports, and aimed at the entire city.

The natives stopped running and trembled in place, waiting for the verdict of fate.

The High Priestess said bitterly, "Your Excellency, what will you do with us if we surrender?"

Lin Yuan smiled: "High priest don't worry. As wise beings, I will not slaughter indiscriminately. As long as you surrender, I will treat you preferentially. I'm not going to interfere with anything within you, and I can build an ecome for you on the ground so you can survive on the ground. I guess you haven't seen the vast world outside for tens of thousands of years. When the time comes, you may be able to return to your distant homeland. ”

The High Priest knew that there is no such thing as a free lunch, and asked, "Do you need us to do anything for you?"

"I don't need you to do anything for me. I would have asked you to continue collecting hedrons for me, but my intelligent machines will do a better job than you. I want you to return to modern civilization on only one condition: to give me everything you have stored, including historical materials, including inventory resources. ”

"As you wish, Your Excellency. ”

The natives on the walls dispersed, and the gates were wide open. The high priest led the important personnel of the temple to respectfully welcome Lin Yuan into the city at the gate of the city.

The two teams behind had already caught up, and they were all very happy to see Lin Yuanbing subduing the underground natives without blood.

The Chinese are not a violent people, and as long as the enemy surrenders sincerely, they will not kill.

In this underground world, Lin Yuan only looked at the resource of fire crystal, and had some curiosity about the history of the Orions.

The High Priest opened the warehouse. The warehouse is filled with a variety of ores and a hill of igneous crystals.

These fire crystals are the savings of the natives for tens of thousands of years, and they only consume a fraction of what they use for lighting.

All the fire crystals add up to more than 2,000 tons.

Fei Yue briefly estimated that 90% of them were first-grade spars, nine percent were second-grade spars, one percent were third-grade spars, fourth-grade spars only looked like one or two tons, and there was not a single one above fourth-level spars.

The total energy of these hedrons is comparable to four or five million tons of helium-three, which is equivalent to two or three moons of energy deposits, and in the depths of the Martian strata, there are obviously more igneous crystals. The key is that the energy density of these spars is quite high, and they are the hard currency of trade exchanges of scientific and technological civilization.

I didn't expect the inconspicuous Mars to be a big energy user, and the extraterrestrial advanced civilization that has been in the solar system for many years is really blind. No wonder the Orions have counterattacked the solar system many times at the expense of their people and money!

Now, these precious energy crystals are surnamed Lin.

Fei Yue held a few big fourth-level spars, her eyes narrowed with laughter, and she kept saying, "Get rich, get rich." With this highly dense energy support, her computer body has a longer endurance and more powerful force output.
