After some arguing, the expedition team divided into three parts and entered the hole.

The first part is Lin Yuan Feiyue and the more than twenty mecha warriors who have been summoned with a physical strength of more than 30 points. Eight of these mechs were half-grown children who had just turned fourteen.

These children are naturally the best among the orphans rescued by Lin Yuan.

The second part is more than 50 elite mecha warriors led by Luan Hongguang and Xu Zhengguang.

The third part is more than 300 mecha warriors protecting Chen Siqing and other scientific researchers who do not have much combat effectiveness.

Lin Yuan thought to himself that these powers were enough to protect the safety of the relatives present. At that time, if he really can't grasp the situation, he can also let the mothership directly evaporate the land, so that the atmosphere inside is completely lost.

The cave is clearly manicured, and the walls are very smooth.

The path in the cave winds downward. Originally, it was very dark inside, but this naturally couldn't help the expedition team, and there were many lighting equipment.

Shortly after the journey, a tall metal gate appeared in front of him to block the way.

Fei Yue detected it and said, "Dad, this is a door made of first-class quantum metal materials. Perhaps it was built by the people inside in order to keep the atmosphere inside from being lost. Originally, there was an energy drive, but tens of thousands of years have passed, and the control center inside should have run out of energy and can no longer drive this gate. We can only destroy physically. But if it is destroyed, I am afraid that the atmosphere inside will be lost. ”

Lin Yuan thought for a moment, asked Fei Yue to notify the robot on the flying saucer to send in the relevant equipment, and then asked the mecha warrior to use the laser sword to cut a hole three meters high and two meters wide on the gate, and then used the materials sent in to build a door-in-door controlled by the expedition team in the hole.

Three gates appeared in a row on the next road, and Lin Yuan did the same.

It seems that when the Martian catastrophe came, the remnants of the people in this underground world did a lot of work to avoid the disaster.

I wonder how they survived the devastating catastrophe in the first place.

Is it because geomagnetic energy is mainly exploding externally?

Entering the last gate, not long ago, the light gradually appeared in front of me.

The crowd quickened their pace and ran towards the light.

When I came to the place where there was light, I realized that the light came from the small metal devices on the walls on both sides.

The metal fixtures are so delicately crafted that you can see that they are densely packed with delicate parts.

In the center of the device is a round red crystal the size of a quail egg, and the light is a metal device that stimulates the crystal to continuously glow through a special method.

The crowd was amazed. What is this crystal? It looks like it's been glowing here for tens of thousands of years without being consumed?

Fei Yue probed for a moment and said happily: "Dad, this is spar energy! I didn't expect there to be spar energy on Mars! It seems that this is the original Orion spar mining site." Hedron energy is extremely precious, no wonder the Orion people did not hesitate to spend a lot of energy to teleport to the solar system to fight An An several times after their defeat. They can't forget it. ”

Lin Yuan smiled and nodded: "Yes, this is a first-level fire attribute spar, which is a high-level energy source of the three-dimensional universe. The Orions below actually used it for lighting, it seems that after countless years have passed, their energy reserves have been exhausted, and they dare not go to the Martian ground to collect energy, for fear of being discovered by An An, so they find a way to use spars to illuminate. ”

The faces of the people who heard their father-daughter conversation were confused.

Who is An An? Why have you never seen it? Sounds like a powerful one.

They didn't know that they were in the third virtual world but they met An An every day.

Fei Yue was very excited: "Dad, with the fire crystal energy, the power of our physical attack missiles will increase many times. Since there is a first-level fire crystal here, maybe there are second-level or third-level ones below. ”

Lin Yuan naturally hoped for the same.

The crowd moved forward again with hope.

This time, less than 100 meters forward, the eyes suddenly opened up, and a vast underground world appeared in front of everyone.

There are hills, rivers, greenery, and all kinds of animals that have never been seen before.

After Fei Yue probed, he said, "Dad, this underground world is about four hundred kilometers long, three hundred kilometers wide, and about four or five hundred meters high. There are many caves on the side walls on all four sides. There is a techno-city in the center. Sure enough, this is the spar mining site of the Orions tens of thousands of years ago. They collected tens of thousands of years of production and did not hand it back, and they did not consume much just for lighting. Looks like we're going to get rich today. ”

With the highly dense energy source of fire crystal, Fei Yue's computer body can operate for hundreds of thousands of years with a few pieces.

Orions are limited to the level of science and technology, and only develop the lighting function of fire crystal. This lighting feature allowed the ecosystem of this underground world to be maintained, allowing the remaining Orions to survive for so many years. And the utilization of spar energy is a piece of cake for Lin Yuan.

Thinking of all kinds of bright prospects, Fei Yue's saliva was about to flow out.

There were traces of human activity here, and everyone began to be cautious and searched forward in battle formation.

Suddenly, Lin Yuan's right hand was raised high, and the team immediately stopped.

At the same time, there was a series of "smack", "snort" and "snort", and several feathered arrows were planted on the ground a few meters in front of the team. Obviously, this is a warning to them not to move forward.

After the leaves in front of him rattled, more than a dozen people wearing animal skins, various cold weapons hung on their waists, and holding large bows emerged from the woods.

The average height of these people is about two meters, their faces are similar to those of earthlings, their hair is golden, their eyebrows seem to have one eye, and their entire appearance is similar to that of Caucasian people on earth.

The man at the head looked at Lin Yuan's group of people. Except for Lin Yuan and Fei Yue, who were a little more normal, the others were all mechas, holding strange weapons, and they were very tall and mighty.

The man secretly beat the drum in his heart, and said hard: "&......%%¥##......%*"

Fei Yue hurriedly said: "Dad, they are indeed the descendants of the Orions. An'an's database has their language in it. As he spoke, he installed automatic translation software in the communicators of everyone in the team.

Seeing that no one on the other side responded, the man blocking the road said it again.

This time, everyone understood. What he said was, "Who are you?" How did you get here? Ahead is the land of our clan, and you are not allowed to go any further!

Lin Yuan didn't bother to talk nonsense with them, and waved his hand: "Subdue them." Don't hurt them just yet. ”

The MechWarrior was immediately activated.

The man understood Lin Yuan's gesture and shouted, "The enemy is powerful, sacrifice!" As he spoke, he pressed his index and middle fingers against his eyebrows.

More than a dozen people led by the man made the same action in an instant.

As a glimmer of light flashed in the center of their eyebrows, an invisible wave rushed towards Lin Yuan's expedition team.

The mecha warrior felt a roar in his head, a feeling of dizziness, and the movement of the forward pounce stalled.

The man's team then bent their bows and fired.

Obviously, the man's tactics are the characteristic mental attack techniques of the Orions.

It's a pity that under Lin Yuan's training at any cost, the mecha warriors not only have a physical strength of more than thirty points, but also a spiritual strength of about a dozen points.

In the face of the Orion's group spirit attack, Lin Yuan and Fei Yue only regarded it as a breeze. The mecha warriors only fainted for a moment before they came to their senses, and clearly saw the arrows fired by the other party.

Just as he was about to dodge, Lin Yuan's voice sounded: "Don't dodge, look at the power of their arrows." ”

The arrows are set on top of the mecha with great power.

The material of the mecha is a level 4 quantum material, and the defensive strength is amazing. The arrow hit the mecha, and it broke into two at once, and there was not even a mark on the mecha.

The mechwarriors simply stood still and didn't attack, looking at the Orions with amusement.

The man saw that the powerful arrows of the past could not even tickle the other party, and shouted in despair: "Run!"

The Orions scattered and fled.

Lin Yuan said: "Let one go and let him go back to report the news, and the others will stay." ”

The mechs in the team quickly pounced, and more than a dozen mechs rushed ahead and exchanged hands with the Orions.

The slower warriors retreated, unable to wipe their faces and besiege the natives.

The natives are also good, flashing very quickly, stretching their legs and punching, making the mecha 'thump'. But it's useless, and the mecha warriors' martial arts are also very proficient, relying on high defense and not dodging, decisively and quickly beating the natives to a bruised nose and swollen face.

After a burst of chickens and dogs jumping at the scene, the Orion man's team was subdued except for one person who escaped, and fell to the ground limply, unable to move.

Lin Yuan walked up to the man in front of him and asked condescendingly, "What's your name?"

The translation software translated Hayashihara's words into the language of the Orionians.

The man glared at Lin Yuan fiercely and said angrily, "Demon, my name is Tonafu. I won't give in, I want to kill or cut you whatever. ”

Lin Yuan smiled dumbly.

What does he want this man to give into? What does this person do to him if he has run out of energy, cannot develop technology, and has degenerated into natives?

Well, maybe there are still some effects. After taming them, he became a miner for Lin Yuan, and it would be good to mine for Lin Yuan here.

Thinking of this, Lin Yuan lost the interest of questioning, informed the team behind him of the situation, and asked the mecha warriors to continue to the central city with these dozen people.

Here, Lin Yuan didn't need to do anything to be on guard.

Slowly, Orions are running out of energy, and they can't use any scientific and technological weapons. Even if they can use technological weapons, how powerful can a first-level quantum weapon be? Even the defense of the mecha cannot be broken.

This is really bullying the natives, or bullying the natives with fourth-level quantum technology. Lin Yuan couldn't help but feel a little guilty in his heart.

Next, the team no longer cared about anything, held a dozen natives hostage, and quickly rushed to the city a hundred kilometers away.
