"Plasma engine OK, the reactor preheating Fan tested himself, he was ready to start his own space exploration, before that she carried out a series of transformations to herself, the foundation of the 250 project itself is good, after replacing the nuclear power engine, there is still a lot of space to place some other things, the head has become a duckbill type, and the tail has a flat tail, the tail is to maintain balance, and there are some detectors for space exploration.

Although the transformation is not big, but on the outside, it seems almost unrecognizable that this aircraft full of science fiction themes is the 250 project, Su Fan, who is equipped with a nuclear-powered engine, has the ability to fly in primary outer space, but because the engine is still nuclear-powered, it can only jump in the two places where the space barrier is loose, and it is still impossible to jump in the same space, at most use the technology obtained from the God of War bracelet to throw down a few coordinates.

Blood jade has arrived in the new world, this new world was named the No. 1 world by Su Fan, so that it is convenient for future management, through the research in that black space, Su Fan found that the black world can lead to many worlds, but unfortunately, her jump engine accuracy is not enough. Crossing is a technical job, and the engine needs to maintain the same frequency as the target world to be able to complete the jump, but the problem is that Su Fan can't master too many frequencies at all, and she can only record four of these frequencies at present, that is, she can teleport four worlds fixedly, and no more.

The first time he took the initiative to cross, Su Fan took a few deep breaths. Although it didn't help doing this, she still couldn't help but use this way to calm herself down, and after calming down, she entered the black space, which is very strange, since the body really left the black space, she only needs a thought to return to the black space, and she doesn't need to start the space engine at all, but if you want to leave the black space, you have to use the engine.

"It's the second world now" Su Fan started the engine after recording the frequency of the engine. I saw her disappear in the black space, and her body twisted slightly. After a whirlwind, she found herself in another black world, and the engine's records showed that she had successfully crossed it.

Su Fan used all the equipment he could observe to observe, but it was a pity. Out of the optical probe. Nothing else will be found. Through the optical probe, the surrounding starlight can be discovered, this world should be a planetary world, and Su Fan can see the surrounding starlight. But there is no planet around that can land, although she has the ability to fly in outer space, but this ability is too weak, if the target is too far away, it will not be able to fly for a lifetime.

"Alternative one, wrong. Su Fan shook his head, regrettably returned to the black space, and began the second exploration.

Exploring the new world is a very boring thing, Su Fan has continuously explored hundreds of worlds, but these hundreds of worlds generally look similar, a dark starry sky, all of which are worlds composed of planets, and the distance is described in light years, with Su Fan's sad nuclear-powered plasma engine to fly for thousands of 80,000 years, it may be possible to fly there, provided that the nuclear fuel in her small fuel tank is enough.

"One thousand three hundred and ninety-two times~" Su Fan recorded the frequency of the engine formulaically, and then started the jump.

This jump didn't seem to be successful, because the surroundings were still dark, but Su Fan was infinitely surprised, because she felt gravity! And in the feedback of various detection systems, she found herself in a very small cave-like space!

"Success!" Su Fan hurriedly turned on the searchlight on his body, and observed the surroundings, the surrounding environment looked like a huge underground cave, and there were obvious artificial traces on the ground under the plane, there were intelligent creatures here! She was very surprised to recover her human form, and took out a bunch of lighting tools to light it up and began to check it carefully.

The ground is hard rock, and there are tall stalactite pillars around it, many of which have been broken by force, opening up a path, and if you look closely on the ground, you can see that there are still faint traces of stalactite pillars in some places on the road.

Not far from the road are those natural stalactite pillars, Su Fan came to one of them and illuminated it with a searchlight on his shoulder, there were some traces of polishing on it, and down the stalactite pillar, she was very surprised to see a broken rope!

This underground road is very wide, enough for four trucks in parallel, I don't know what the people of this No. 2 world have to do to build such a road underground, but since this road is so spacious, and the wear and tear on the ground is very serious, it means that there are often people coming and going, Su Fan thought about it and took out an all-terrain vehicle, and rode this four-wheeled car down this road to see where it leads.

This underground space is really large, and she walked along this wide road for hours without seeing an end, but she was not alone in the cave, in the stalactite forest on both sides of the road, she felt something peeking at her, she threw a cold firework over, and a dazzling white light lit up from the darkness.

Whoop~ A terrible wail came from the surrounding darkness, and with the help of the light of the cold fireworks, Su Fan saw that there was something next to the owner of a stalactite that was covering his "head" There wailing, this thing is generally humanoid, but the body proportions are very strange, the body is very small, but the limbs are very long, the image is a Lantern Festival with four chopsticks inserted on it, the head of this thing should be the head is not spherical, but a hemispherical shape directly on the body, there are four round holes on the top of this head, from the order of arrangement, it seems to be the eyes, nose and mouth.

"This can't be the intelligent creature of this world, right?" Su Fan grew his mouth. This thing is also too weird, probably because it lives in the dark underground all year round, and the eyes are extremely sensitive to the light source, and there is no natural light source in this underground space, and those glowing mosses are, because the eyes are too sensitive, so a high-brightness cold firework directly flashes the dog's eye.

However, after observation and analysis, Su Fan denied this speculation, because this thing had no clothes on its body, and it should just be an underground creature. Su Fan had found a rope before. That means that this world should already have textile technology, and no matter how bad it is, it's animal skins or something, but there is nothing on this thing.

Throwing the unknown thing aside, Su Fan got on the all-terrain vehicle and continued to move forward. She's weird. It's obviously an underground space. There is no air flow, but the quality of control is surprisingly good, it is like the fresh air of the forest in the evening. Could it be that there is something strange about this underground space?

Just as Su Fan was moving forward with a strange face, she suddenly heard the sound of a fight coming from the front, and through her keen hearing, she heard the voice of a human being! That's right, it was the voice of a human being, because the language shouted by the human beings in front of her was very familiar to her, and it still sounded like the language of the old world! She didn't have time to wonder why the three seemingly unrelated worlds used the same language, and now that there were finally human beings, of course she had to go up and learn about this world.

After advancing for about ten kilometers, Su found a convoy, from this convoy, she didn't see any livestock, it should be a kind of vehicle that moved forward on its own power, and after she looked closely, a strange expression appeared on her face, because these vehicles did not have wheels but four or six legs!

After observing these vehicles, Su Fan continued to observe those people, these people looked like human beings, their equipment was some heavy armor, all of them had similar weapons, the weapon in the left hand was a self-powered weapon like a chainsaw, and the right hand was holding something that should be a firearm, they were being attacked by a large number of monsters that Su Fan had blinded with flashbangs just now, and these humans used the cover of the vehicle to continuously kill and injure the surrounding monsters with two weapons.

The combat effectiveness of these human beings is not weak, although the number of monsters is several times that of them, but they are not a little flustered, and there are no casualties slaughtering monsters in an orderly manner, Su Fan also wants to use this to study the humans in this world, and she did not help.

There is nothing new about the chainsaws in the hands of these humans, but their weapons aroused Su Fan's idea, and the pistol did not seem to shoot live ammunition, but a kind of energy ball, which would turn into a ball of flame after hitting the target, and those monsters would be burned to ashes as long as they were hit once, but the physical attack power of this firearm seemed to be very sad.

And the armor on human beings is even more black technology, and it is actually motivated! From their backs, you can see some energy circuit-like pipes, every time the energy circuit behind a soldier lights up, his speed will become much faster for a period of time, the attack is sharper, a punch can throw a black monster to the ground and die, and they all try to avoid exposing their backs to enemy attacks, and their companions are constantly covering the backs of their teammates, where the energy pipelines are very fragile, as long as they are caught by those black monsters, those humans who have been hit in the back will no longer be able to launch that kind of rampage。

In the convoy, Su Fan also saw a very strange phenomenon, although these people were using weapons that looked very tall, but the tools they used for lighting were still chemical energy, to put it bluntly, it was all kinds of oil lamps or something, and they didn't see any other equipment in the dark, what was going on?

Under the arming of these special weapons, those monsters are not enough to see at all, Su Fan also completed her observation, she took out a heavy sniper rifle from behind and began to name those monsters in the dark, a large-caliber bullet can break those monsters in two, and the battle ended quickly after Su Fan's intervention.

Those monsters won't run away after attacking.,The final result is, of course, all killed.,After the monsters disappeared.,Humans didn't relax The sound and light effect of large-caliber sniper rifles firing at close range can be seen even by the blind.,Although the bullets just fell on the monster's head.。 But those people were still very careful to be on guard.

Of course, Su Fan had no hostility towards these people, after she put on a helmet to block her face, she walked out of the darkness and saw the elusive gunman just now walking into her sight, the vigilance of those humans was temporarily lowered, and it was very likely that there was no hostility.

"I'm not hostile. Su Fan carried the sniper rifle in his hand, and when he saw Su Fan's action, those who were on guard completely relaxed.

"Where are you going?" came a large black man with a blue stripe on his armor, who was supposed to be the leader of the group. "My name is Bloch. It's the leader of this team, I'm sorry, we're an army, and we're escorting a batch of supplies. So please stay away from us. It's the rules, you know."

"Okay, okay," Su Fan raised his hands. Signaling that she was not hostile, she stood at a distance of about ten meters from the convoy, "I'm lost." I finally found a way, where does this road lead?"

This is the excuse that Su Fan has come up with, she has seen several entrances to the caves along the way, but there are no traces of artificiality, she is here to find people, and there is no random drilling, honestly walking on this road, this excuse should be very good.

"Lost, you're so lucky," Broch nodded, it was no longer awesome to get out alive after getting lost in the underground cave, "you can walk along this road for six hours to reach Papan City." ”

"Papan? Okay, thank you. Su Fan nodded and retreated into the darkness.

Broch also breathed a sigh of relief, although there is such a rule in the army, prohibiting others from approaching the army at a certain distance, but the person's marksmanship in the dark just now gave him great pressure, if she was angry, I was afraid that her convoy would fall under the terrible shot, after Su Fan disappeared, he ordered to clean up the battlefield and continue to move forward.

Su Fan did not leave, she lurked among the surrounding stalactites to observe the team, the bionics of people in this world has reached the pinnacle, the speed of walking with legs is very fast, and the seemingly stout machinery retreats on the ground without much noise, and the body is very stable under the drive of mechanical retreat, no worse than those ** suspended wheeled vehicles.

There were a lot of hooks on the outside of these walking vehicles, and the soldiers who were guarding the convoy just now hung the hooks on their shoulders on the body of the vehicles, and as the vehicles advanced, they had fully adapted to this mode of transportation, and they didn't seem to feel any discomfort, while looking around vigilantly, while chatting with their companions where they were having a ride.

What is the best way to understand a world, of course, is to chat, but Su Fan doesn't have a little understanding of this world, this method is obviously not good, so eavesdropping on other people's chats is the best way, most of the content of these soldiers' chats is the matter of hanging a certain color and blood color lamp, which PP is the largest, which European faction is the softest, etc., these people have been trekking in the dark for more than a month, and they are about to arrive in the city, of course, they have to think about how to relax themselves.

Of course, in addition to these workers' conversations, Su Fan also heard some useful ones, such as these people live underground! They are from another city, that city is also an underground city, connected to this Papan City through a complex karst cave system, they have grown up underground since they were children, and when they joined the army as adults, they traveled back and forth between Papan City and their hometowns, and the humans in these cities live underground all year round, Su Fan did not hear any words about the "sun" from these people's dialogues at all!

"This group of people is not a mouse, right?" Su Fan said to himself, they had never seen the sun before! They all lived underground, could it be that there was a nuclear war on the ground, and these people were hiding in the subway? Why did they have such a sense of immediacy?

Forced to rush out and ask an understanding **, Su Fan continued to follow the convoy, collecting the information he needed, in addition to these people living underground, there is also a thing that human beings are not the boss in the underground world, and there are also existences that can compete with them, one of them is the kind of monster just now, this kind of monster seems to be very common in the underground world, and there are very many of them, they like to lurk in the dark and then suddenly kill in groups, kill humans and then run away.

These things called black monsters seem to be just killing for the sake of killing, after killing all the humans, they don't eat the corpses, just tear the corpses apart, destroy all the vehicles and other things of the human beings and leave, and their number seems to be endless, coupled with the complex underground cave system, the human beings have no way to do these things, they can only defend passively, of course, if a den is found very close to the city, the human race will also uproot the den at all costs.
