Normally, the core part of a planet is searing.

Not only is most of the energy in the early stage of the planet's birth sealed in the earth's core, but at the same time, in the early stage of planet solidification, the hot molten material generated in the planet's interior will also be transferred to the earth's core under the action of gravity and osmosis effect. Eventually, the Earth's core is heated into a searing ball of liquid metal: under incredible pressure and temperature, even diamonds become butter-soft, and no matter how high the temperature, matter can only liquefy here, not vaporize.

The above is the normal version of the Earth's core.

Some cores are cool—cold compared to scorching cores. Even long-lived planets are coming to an end in continuous evolution, the activity of the earth's core will gradually decrease, radioactive materials will slowly decay to the point where they cannot release heat, the whole planet from youth to middle age is the process of cooling from the surface to the core layer by layer, and in the case of being far away from the stars, this cooling rate will be faster, when a planet enters old age, the core will become close to the freezing point of iron metal, after peeling off its crust and mantle, you will see a dark red alloy ball, In the desolate space, the vicissitudes of time are revealed, and the lonely, cold and cold flames that slowly dim are the twilight candlelight of an old planet.

The above is the literary version of the earth's core.

There are also some cores that go the non-mainstream route, and the skilled demolition team throws the entire core of their planet into the middle of nowhere, leaving a warm burning rock crust that provides heat and light, and then they plant some huāhuā grass in the big hole in the center of the planet, and then insert a theme park sign - this kind of core let's call it the ** version.

"This ...... What the fuck is it? "I was dumbfounded when I looked at the bright underground realm and the green land in front of me.

"This ...... What the fuck? Looking at the giant vines that moved slightly on the green earth, many kilometers wide, Lilina was also dumbfounded.

"A small planet? Stuffed inside the Earth's core? The corners of my sister's mouth twitched a little, and the vegetation was dense. They're so huge. ”

"Maybe it's because of the direction of gravity?" I'll let 700 billion descend slowly" The gravity of the green core below is one-thousandth the surface of the earth, and the surrounding mantle almost cancels out the gravitational pull in every direction. ”

"Perhaps." Sandora said noncommittally, she probably felt that the huāhuā hastily growing in the center of the earth was not a matter of concern.

It took us a long time to get through the mantle layer, partly because the 700 billion slowed down the cruising speed, and partly because the alloy tunnel was not straight: it followed a gentle parabola to the center of the earth, and halfway through it seemed to bypass some of the megastructures buried deep in the mantle, and the radar showed that the megastructures that were bypassed had an extremely high energy response. Maybe they're the Ghost Forge of Green Star or something. When I passed through the last layer of spherical shell barrier, I thought I was going to enter a sea of fire, which under normal circumstances would have been a scorching, molten iron purgatory, but in fact the sea of fire did appear, but it was behind us: the center of the earth was hollowed out entirely, and the core was gone. Only the inner spherical crust of the Earth's core (or the lowest layer of the mantle) is sprawled with burning rivers of magma that flow on the partially cooled mantle, like an upside-down earth and an upside-down river, lake and sea. The mantle in the field of vision is black and red, indicating that their temperature is at least below the melting point of iron, and the thick liquid rock and metal flow slowly on the inverted earth, like a dazzling fire dragon.

In what was supposed to be the core of the earth, there was a very contrasting scene: a sphere with a radius of 1,500 kilometers was suspended there, as if it were another small planet, and its surface was free of rushing magma and iron flows. There is no burning sea of fire, on the contrary, under the protection of a layer of dim barrier, this "star within the star" with a radius of 1,500 kilometers is densely covered with lush green vegetation.

It is so dense that it is completely invisible.

"Jun, to be honest, I've never seen anything like this in tens of millions of years," even Sandora said slowly with her eyes wide open and in a tone of surprise. "It's ...... Beauty. Spectacular, technically not incomprehensible. But the ingenuity of this project is simply ...... Unbelievable. ”

Eventually, she described the magical star in front of her in disbelief.

700 billion slowly hovering on the gravitational equilibrium point, 537 kilometers from the bottom of the mantle, 200 kilometers from the small green planet below, here, the gravity is zero, this is a very wonderful phenomenon, for a normal planet, its gravitational force points to the center of the earth, there is no hole near the center of the earth, but the instrument shows that after passing through the demarcation line at the bottom of the mantle, we have entered a modified gravity environment, part of the gravity comes from the small green planet in front of it, pointing to the center of the earth, The other part of gravity is in the mantle layer in all directions, and it is pointing in the opposite direction: at the surface. This is definitely not a natural formation, perhaps this is some kind of safety device for the Green Star, the original builders made the gravity of the center of the earth face in two directions, forming a wide enough safety zone in the middle to prevent the flowing magma and molten iron from falling on the ecological planet below like a waterfall, and also like an invisible cushion, so that the core planet can avoid crashing.

Tavel took a deep breath and released a set of twenty-two probes, then waited for the information to come back. It can be seen that even a super scientist like her is a little excited at this time, in Sandora's words, maybe the wonder in front of her can be explained from the technical point of view, but this creativity, and the intention of this magnificent project, are incredible.

"There are two earths, but no sky" Because of the loss of gravity, shallow simply floated back and forth in the back half of the unusually wide carriage, she grabbed the window and looked outside, her body dripping and spinning, "one is burning with fire, the other is growing forest, I saw this in my dream when I was a child, both ground are upside down......"

I thought about it, and finally understood: she was confusing Alice's adventures in Wonderland with the Journey to the West Flaming Mountain, and of course it was possible that the Demon God Altar Fighter was mixed with the Third New Tokyo......

Now there is no concept of up and down in this place. The bottom of the mantle is the equivalent of the sky to the little green planet, but the other way around it is a burning earth, but out of habit, we still think of the "star within the star" in front of us, which has a radius smaller than the moon, as below. Tavel completed a preliminary assessment of the environment: "The maximum temperature of the upper mantle layer is only about 3,000 degrees Celsius, and the minimum temperature is 700 degrees Celsius, which is very uneven, and there may be an energy system that is still regulating the geocentric temperature environment of Green Star." The green core is a medium-density celestial body made up of soil and rocks. The vegetation on the surface is confusing: so many plants, but on the device they show a life reaction, it is too abnormal. ”

"Is the whole planet a single organism?" Sandora looked interested, "Let's go down and have a look." Tavel, have your assistant stay at the gravitational equilibrium point for the time being and continue to observe this geocentric object. I've always felt that this has something to do with the dormant pods in the mantle. ”

A team of scientists opened a makeshift platform at the gravitational equilibrium, a triangular floating island shrouded in a spectral shield, and we descended slowly on 700 billion, careful because Tavel was afraid that we would destroy the little green planet ahead.

"The center of the earth is filled with thousands of degrees of hot air" Tavel pointed to the star inside the star, which was covered with a dark barrier more than ten kilometers above it, "This barrier protects the biosphere inside, you better turn off the ghostly shield of the aircraft first." The barrier outside the target doesn't seem to have much energy left, and the spectral energy might make a big hole in it. Theoretically, yes. ”

I can guess if she doesn't say the rest of the story: the fragile plants on the star will be wiped out in a fire, and I am afraid it won't even last a few minutes.

Seven hundred billion closed shields, relying only on armor layers and airtight force fields to resist the thousands of degrees of heat outside: but this is nothing for Empire-made vehicles. Everyone couldn't help but get nervous as they passed through that fragile shield, and I was ready to activate my abilities to plug the loopholes as soon as the situation got out of hand, but luckily everything went well, and the dim shield over the little green planet withstood the test, it only flickered partially.

We slowly landed in a dense primeval jungle, and the seven hundred billion scorching shells scorched some plants. Overall, though. This landing is still quite environmentally friendly.

"It's very close to the environment of the new Eden IV, and the temperature is slightly higher. The air is oxygenated, but not very suitable for human habitation: the oxygen content is too low, and gravity is not enough. ”

Sandora said as she jumped on the spot, "There is artificial gravity under the shield, but the strength of gravity is only a little greater than the surface of the moon, if it is not intentional, it is that the artificial gravity system here needs a major overhaul." ”

"I hope it's not the latter" Tavir muttered, pulling out two sophisticated hexagonal devices, I feel more and more like a robot cat, always pulling out a bunch of high-tech from her personal space, "Swap two life detectors, and the result is still the same, there is only one creature here, and that is the planet beneath our feet: if it were a planet." ”

Of course, it's a planet, anyway, I don't believe that under normal circumstances, the Earth's core can shrink nearly a thousand kilometers away from the mantle, and then cool down, and grow on it with huāhuā grass, and at the end of the day, its own rotation period and angle: this is the conclusion after the 700 billion scans just now. I feel a little lucky now, the system composed of the green star and its "star within the star" seems to have a set of self-protection devices, which ensures that it is still stable after being dragged by the emperor ** and transferred to the world realm, otherwise this small green star will definitely crash into the mantle. However, this system is not unexpected, after all, the Green Star originally had the ability to sail across the world, and now it is just the scrapping of the superworld world, and the safety lock prepared for this engine does not necessarily have to be scrapped, right?

The faint gravity, the unspeakably lush primeval jungle, the gigantic plants, walking in such a place, we can jump more than ten meters in the air with a casual jump, it feels like walking in Alice's dream world, when I walk past a huā that is at least three stories high, I feel that I suddenly understand what Dingdong's usual perspective is.

"I think there's a sense of incongruity here" Sandora didn't like the feeling of microgravity piercing through the trees, so she simply floated in the air and whispered, "There is a part of it that is unreal, these huge vines on the ground are fine, but ...... Wait a minute. ”

Sandora froze suddenly, and a golden glow slowly flowed through her hair. She felt her surroundings for a moment and nodded, "I see, I was negligent." ”

As she spoke, she casually pressed her hand on a huge bush, and the amount of spiritual power only lightly impacted, and the sturdy-looking plant turned into a floating green point of light in the blink of an eye.

"It's a mass projection" Tavel reached out to catch the points of light, watching them slowly reassemble into a large, colorful bird the size of half a Pandora. The current Tavel is a mass projection, I haven't used this kind of thing, it's hard to imagine what kind of feeling this form of body will have, but I've heard of the characteristics of this technique, which can create a mirror image that is exactly the same as the main body, and the mirror image has a substance. It can affect the material world like an ordinary body, and can even simulate the strength of the body's limbs, but the mass projection cannot carry the special abilities of the body, such as the large number of scanning components in the body of the Xiling Apostle: the mass projection is just a convenient terminal for work, tangible and godless. Therefore, Tavel needs to use various external devices (scanners, probes, etc.) to work with quality projection, and the functions of these devices are inherent in her body, which is why she was not able to detect the anomaly of the environment here in the first place. It was Sandora who discovered these secrets, "much less stable than the projections made by the Imperial Technique, but the visual effects are much more realistic, and it is impossible to distinguish the real from the fake if you only use the regular senses." However, any kind of energy radar can detect the inauthenticity of these projections: they have a single energy response, and there are no signs of life. ”

"In other words, only these vines under our feet are real, and everything else is an illusion."

My sister nodded, she didn't really like the feeling of being fluttering here but not tripping over vines, so she floated in the air side by side with Sandora. Floating forward.

I don't know what came to mind. He crawled to the top of a plant and shouted, "Is there a person?" Anyone—to talk back—? ”

I hurriedly went up and dragged the girl who was convulsive at any time down: "What are you yelling about?" ”

"Don't say it. She's not shouting," said Sandora, smiling, "I feel something just emerging from a distant vine and approaching here. ”

We stopped in amazement and waited patiently for a while, and after a few moments, a huge clump of leaves suddenly rustled not far away, and then, in the amazement of everyone, a little girl with pointed ears and a hunting bow on her back came out from behind the blades, and her bright light green eyes looked at this side in shock.

The little girl was wearing light underwear that was very suitable for walking in the woodland, white shirt, with green huā patterns on the edges, the clothes were not made of any material, a little close to leather, but they were unusually soft, and she was wearing a pair of small boots tied with leather ropes, and the boots were still stained with mud, the girl looked twelve or thirteen years old, slender but not thin, with short green hair, and a pair of pointed ears poking out of the short hair. With small and delicate facial features, fair skin, and the girl in the sleeping pod we found "above" has similar facial features, and my eyes fell on the other party's hunting bow - it was obviously a toy, first of all, its volume was completely designed according to the figure of a twelve-year-old little hairy girl, and it was estimated that it was not much power when it was full, and secondly, there was a small grass doll tied under it, how did this thing look like something that should be on a weapon, of course, the most important feature was the quiver that was crossed with the hunting bow, The arrows in the quiver were scattered in a mess, some pointing upwards, and I could swear by the discipline that this kind of bow and arrow, which was made with a leather plug as an arrow, was absolutely only intended for children under the age of fifteen......

"Quality projection."

Sandora said in the spirit link, and I knew that the little girl in front of me was not real.

"Ahh Intruder! ”

The little girl looked at us for five or six seconds before she suddenly reacted, then clumsily took off the small hunting bow on her back, bent the bow and set the arrow with five seconds, and then hurriedly turned the arrow around and rushed towards us, and then aimed for a long time, and then pulled the bow for a long time before she said with a crying voice: "Don't move, I'll aim in a while, you wait a while......"

Everyone: "......"

"Dingdong doesn't have to worry about his intelligence." Lin Xue deceived her head and whispered.

Then an arrow with a leather plug arrow finally broke through the air, swaying and knocking on Lin Xue's forehead, and it was stuck there with a "pia" sound. The eldest lady's face froze, and I turned my head and poofed: I can't see it, this stupid little girl is quite accurate, and she shot her head with an arrow.

"Ah, I'm sorry, I wanted to shoot the man's knee, I missed ......" The little girl's panicked voice came from the front.

Me: "......"

A circle of people poofed!

Lin Xue pulled out the non-lethal toy arrow on her forehead and threw it back to the little girl, and then walked forward, the little girl followed step by step, with a nervous face: "Don't come here!" Intruder! This is a forbidden place! No one can come in! If you go out, the patriarch will be angry! Hurry up and get out of ...... Wow! ”

The little girl stepped into the air, fell from the vine and sat on the ground, and began to cry.

Sandora frowned, her tone full of helplessness: "Ah Jun, if someone uses quality projection just to make such a joke on us, then this is really bad enough." ”

"There is no hostility and no danger." Lin Xue shook her head and said, and then ran forward with her sister to help the little girl who was hurting down, I felt a little disobedient, and after thinking for a while, she said to Sandora: "Eh, by the way, will the quality projection hurt?" ”

"Well, the mass projection theoretically ignores too strong physical sensations," Sandora shrugged, "but the mass projection here uses a different technique than the Empire, so it's impossible to say, maybe they integrate the real sensation into the projection, although I think it's a pretty stupid idea." ”

After a period of confusion, my sister still succeeded in calming the messy little girl, maybe some kind of bear child control aura had the effect of re-production, the little girl was brought to us, with tears in the corners of her eyes, and looked at us timidly: "You don't eat people, do you?" ”

I...... I'll go! What the hell did we pick up and come back, why are there such strange creatures in there!
