After a few moments, Xin Lin came out of the trade area, did not make any stops in Bartolok City, and flew directly to the passage in the center of the city.

The diameter of this cave leading to the first floor of the underground world was nearly a thousand meters, and as it got closer, it was like a huge beast's mouth swallowing it. All the time, all kinds of flying machines and fire beasts come from all directions, flying in or out of it.

As he approached the entrance of the cave, his telepathy sensed that there was anti-aircraft fire all over the vicinity, and at least a hundred turrets surrounded the hole, forming an impermeable network of crossfire.

These turrets are no less powerful than the main guns of meteor-level battleships, and they are hidden under a massive energy shield system, which is not activated at this time, so they are very hidden.

If someone breaks through the passage, the end will be very miserable.

There is a metal fortress-like floating island above the exit of the passage, which is a checkpoint set up by the Yan Scale Clan, Xin Lonely flew over unhurriedly, and paid a lot of tolls with the identity card he had just handled, and then he was released.

Xin Lin flew into the entrance of the cave, and the passage was brightly lit, and you could see that it was not perpendicular to the ground, but extended downward with a slope of about 45 degrees, twisting and turning, and there was no end in sight.

Most of the passages of the Flame Scale Star are naturally generated, but they are not very regular, so there are traces of artificial trimming, and there are bunkers and sentry posts built on the inner walls every few hundred meters, and a large number of Flame Scale warriors are stationed there, leaving nothing for outsiders to take advantage of.

Xin Silence flew through the passage at high speed, descending towards the ground.

The armored light brain showed that he was moving away from the ground at a speed of ten kilometers per minute, and the temperature around him was rising little by little. It wasn't until six minutes later that the slope of the passage gradually subsided, and a red light lit up in front of it, and then the vision widened, and it flew out of the passage to a huge defensive fortress.

This fortress resembles a pre-Industrial Revolution wall, built at the exit of the passage, and beyond the walls is the underworld!

Xin Lonely's first impression is red, and then heat.

In the underworld of Scales, there is a fern called Miscanthus, which is extremely tenacious, not only able to resist high temperatures, but also absorb heat and release a faint shimmer.

Although the brightness of this glimmer is not high, the fire miscanthus is everywhere, accumulating a lot, illuminating the underground world on every level.

It is the most abundant species in the Underworld, at the bottom of the biological chain, and provides food for countless herbivores. The more places with the fireweed, the brighter it becomes, but this light is all red, as if to clothe the whole world with a red veil, filling the vision of all living beings.

In the glow of the miscanthus grass, a scorching wilderness unfolded before the eyes of the bitter silence.

This wilderness is boundless, overgrown with weeds, and the geography is similar to the surface of the planet, like a plain, and the distant horizon has no end in sight.

If you don't look up and see that there is a rock top several kilometers high above, instead of the sky, it is hard to imagine that this is more than fifty kilometers underground!

Xin Lin looked up at the top of the rock and found that the fire miscanthus grass was really growing wantonly, and large swaths hung down from the top, like chandeliers, to dispel the darkness of the enclosed space below.

He didn't rush to leave, and telepathically swept through the fortress and walked into a shop that sold transportation tools.

The most important tool for action in the underground world is the means of transportation, otherwise relying on the energy of power armor alone, it will not be able to go far in a huge world of hundreds of layers.

It didn't take long for Xin Lin to ride a four-meter-long maglev motorcycle out and plunge headlong into the vast wilderness.

In just a minute, the fortress at the exit of the passage was far behind him, and he could not be seen.

In the high-speed driving, the violent wind was blocked by the invisible magnetic field, whistling from the side, Xin Lonely had not driven a motorcycle for a long time, and the feeling of being lost for a long time came to his heart, quite a little happy.

However, he was not careless, and as he got farther and farther away from the exit fortress of the passage, the danger would slowly approach.

Xin Silence maintained the maglev motorcycle at an altitude of one meter above the ground, and the speed was about 300 kilometers per hour, no faster, and at the same time, the telepathy had already been released, constantly scanning the movements within a kilometer around him.

Whether it is the information collected in the Federation or the memories of the Takas, it is clear that there is one important thing, that is, in the underground world, you must act close to the ground.

Don't fly into the air until you have to!

This is because the geology under your feet and above your head contains a huge number of empty star stones, which interfere with each other in the air, distorting space and forming turbulence where there are no ores. This kind of space-time turbulence is simply ubiquitous, in fact, even on the ground, but to a lesser extent, the higher above the ground, the greater the chance of encountering distorted space.

Once a person or a vehicle collides with a distorted space, the matter will be deformed and squeezed, and it will fall down; In the worst case, it was directly crushed into powder, and the machine was destroyed and people died.

Even if it is a star powerhouse, it is powerless to resist this kind of distorted space, so it can only be avoided from afar.

Distorted space is invisible and difficult to detect, and it is generally only detected when you get very close, and the distorted space is moving at any time, and many times it is too late to find it.

The aircraft manufactured by the Flame Scale Clan all have the function of detecting distorted space, but the effect is unsatisfactory, and the detection distance is only two or three hundred meters, so they can only avoid it first, fly close to the ground, and the driving speed cannot be too fast, otherwise they will hit it headlong as they find the distorted space, which is equivalent to killing themselves.

In the underworld, many flame beasts are naturally extremely sensitive to distorted space, and the ability to avoid distorted space is deeply engraved in their genes, and they can safely dodge all distorted space and soar freely in the sky without even looking at it.

Therefore, the talents of the Flame Scale Clan did everything possible to tame the Flame Beast, and would rather give up the convenience of the flying machine and use the Flame Beast's ability to open up the underground world.

Xin Lin had already urged the singularity star core, and his gaze passed through the layers of space, as if he wanted to see through the essence of the world.

In his telepathy, the space around him was extremely disordered, far less stable than elsewhere. In the sky and on the ground, strange invisible fluctuations are emitted everywhere, they interfere with each other, like ripples on the water, like the ripples on the water, the teeth of dogs are intertwined, because of the difference in wave frequency, some cancel each other, some resonance strengthen, and the gravitational effect that ordinary people cannot see occurs all the time, which dazzles him.

"These are spatial fluctuations!"

Xin sighed secretly, in his eyes, the space used to be as calm as an ancient well, unchanged for eternity, and as solid as steel, but here, the space changes anytime and anywhere, it is unimaginable.

"Huh? That's ......"

He turned his head to look at the sky above his left, and telepathically detected that there was an extremely volatile space about six hundred meters away, less than two meters in range, like a strange vortex appearing on the surface of the sea, refracting the light that entered it, this is distorted space!

Xin Silence slowed down the maglev motorcycle, taking a closer look at the distorted space.

I have to say that the distorted space is really very hidden, and when I swept through my telepathy, I found that the light was very faint and abnormal, and it was similar to other places.

Even for a high-level warlock with extremely keen perception, it would be too difficult to discover the distorted space so far.

But all of this is telepathic, and there is no way to hide.

Xin Lin understood that this was his great advantage in the underground world, as long as he kept his telepathy at all times, the warped space did not pose any threat to him.

Thinking of this, he laughed, and without any scruples, the speed of the maglev motorcycle soared sharply, with a speed of more than 500 kilometers per hour!

As the maglev moves forward, the surrounding environment gradually changes, from plains to hilly terrain, but the temperature is still the same hot. Farther and farther away from the fortress, the surroundings became inaccessible, all kinds of fire beasts and insects lurked in the tall and dense grass and trees, Xin Lin avoided them one step ahead of time with telepathy, and there was not a single battle.

His destination is the Sky Well that leads to the deeper underworld.

The empty star well is actually a weakened gravitational well, and the space channel formed by the large concentration of empty star stones is sometimes referred to as the "star well", which is similar to the "star gate" that everyone knows in the universe. Stargates connect major river systems for teleportation across galaxies, while starwells have a much smaller teleportation distance and can only connect the layers of the underworld.

There are hundreds of layers of the Flame Scale's underground world, except for the top dozens of layers, which have some naturally formed geological channels, most of the deep underground world is entered and exited through the star well.

Almost every layer of the underworld has star wells, and the number of them is more or less, and generally the larger the area of the underground world, the more star wells are formed.

Xin Lin is now on the first layer, and the map shows that there are hundreds of star wells in this layer of hundreds of millions of square kilometers of the world, and all of them are stable, leading to different levels.

The nearest well to him was three thousand kilometers away, but it led to the third level.

Xin Lin wanted to reach the 107th floor as fast as possible, and the navigator calculated the optimal route, he had to go to a star well 5,000 kilometers away, which led to the eighteenth floor, and then enter the forty-second floor from a star well on the eighteenth floor.

After five times, they reached the 107th floor where the fire source crystal vein was located. At his current pace, it would take a week.

The wind and lightning all the way alarmed countless flame beasts, but the strength of the fire beasts on the first layer was very weak, and they couldn't catch up with the speed of the maglev motorcycle.

Occasionally, some explorers were frightened by the speed of the silence and cursed at his back.

Xin Silence ignored it, and a few hours later, halfway through the journey, he was about to stop and rest, when suddenly a flame beast in front of him entered his mental force field.

"Molten Snake." He immediately recognized it as a molten snake.

The Molten Serpent is a very common firebeast, found on almost every layer, and has two red lines like lava on their sides, hence the name. The poison of the Molten Snake is not strong, and its general strength is also very weak, and the threat to explorers is not great, and it is already rare for the strength to grow to a first-level flame beast.

What surprised Xin Lin was that this molten snake turned out to be a third-level flame beast, nearly twenty meters long from head to tail, and the snake's body was as thick as an ordinary person's waist, and I don't know how long it had lived to survive to this point.

He locked his telepathy onto the snake's body, probed into it, and suddenly perked up: "Empty Star Stone!" ”

Usually only flame beasts above level four will exist in the Empty Star Stone, and in the belly of this molten line snake, there is an olive-sized Empty Star Stone, comparable to a sixth- or seventh-level flame beast, it is really incredible, it is like winning the lottery.

He had been flying all the way for so long, and it was the first time that he had found the Empty Star Stone in the body of a flame beast.

Such a large Empty Star Stone is worth about 150,000 Yan Coins, which is four to five hundred million Federation Coins.

For the wealth sent to the door, Xin Lin naturally has no reason to refuse. Without hesitation, he adjusted the direction of the maglev motorcycle, and rushed directly at the molten snake hiding behind a pile of rubble.

With a roar, the Molten Snake was immediately alarmed.

It raised its huge triangular head, its narrow eyes stared at the high-speed maglev motorcycle, and when the maglev motorcycle approached only a dozen meters, it opened its mouth to spew out high-temperature flames, and suddenly its whole body could not move, as if it was pressed under a big mountain.

The maglev motorcycle stopped in front of him, Xin Silence got out of the car leisurely, drew his lightsaber, ignoring the frightened gaze of the molten snake, the lightssaber accurately cut through the scales, and made a short incision, and then, the bloody Sky Star Stone flew out of the wound and fell into his hand.

The sky star stone is translucent, very light in color, reflects beautiful light, and has a somewhat similar appearance to diamonds. Xin Lin took it in his hand and weighed it, the quality of this empty star stone was about two hundred grams, and the price was about the same as the previous estimate.

"Windfall, not bad."

He laughed, put away the Sky Star Stone, and then looked at the molten snake on the ground.

As an ordinary snake that can grow to a third-level flame beast, this molten snake is not easy, so Xin Lin didn't kill it, but just took out the Sky Star Stone. The lightsaber cut in just now to avoid the vital point, and it didn't take long to heal.

"For the sake of you contributing the Sky Star Stone to me, spare your life, go." Xin Xiao said and let go of the shackles of the Ten Thousand Magnetic Net.

The molten snake has a certain amount of wisdom, and has long been scared half to death, realizing that it can move, and quickly flees without looking back, burrowing into the grass and disappearing.

Xin Lin returned to the car and continued to move forward, perhaps because of good luck, it didn't take long to find a flame beast with an empty star stone in its body, but it was very small, only a few dozen grams in mass.

The flame beasts of the first layer of the underground world were no more than level three, and they had no power to resist in the face of Xin Lone, they only needed a ten thousand magnetic net to control them, and then easily took away the Empty Star Stone. After collecting the Empty Star Stone all the way, after half a day, when Xin Lin arrived at the Empty Star Well, he already had four Empty Star Stones in his hand, adding up to more than 400 grams and worth more than a billion Federation Coins!

This starwell is located in a canyon, and from a distance, you can see that a wide square has been built in the center of the canyon.

In the center of the square, there is a distorted space that can be seen with the naked eye, and in telepathy, this space with a diameter of more than thirty meters is distorted into a funnel-shaped, and the bottom of the funnel leads to no one, and even telepathy cannot detect the opposite side.

At this moment, there are two groups of people facing each other in the square, they are surrounding the empty star well, and they are tense, and it seems that they are about to make a move at any time!
