Star Crystal is a very high-order material, and besides, it's not just an eighth-order.

There are three levels of Star Crystal, which are the seventh, eighth, and ninth order.

The formation of star crystals is that after the collapse and contraction of the planet, some substances on the planet are condensed together due to strong gravitational effect, this kind of material is very special, not any planet can be, such as the sun, if the sun collapses and contractions, it will definitely not form a star crystal, because there is no special substance in the sun.

This white dwarf can form star crystals, which means that this planet was quite unusual before, but it doesn't matter, Lin Feng doesn't pay attention to the planet's past, anyway, he only knows that he is going to get rich.

As an eighth-order star, its price is of course very high, although it is far inferior to the ninth-order material, and it can't be compared with the heart of light and the heart of darkness, but the star crystal is generally superior in quantity.

Such a big planet, if the planet is full of Xingchen crystals, the value is at least trillions, Lin Feng just refined the sixth clone some time ago, and consumed a large amount of spirit jade, and now he is short of money, and now these Xingchen crystals can just make up for some shortfalls.

However, Lin Feng threw the Xingchen Crystal in his hand to the ground, not that he didn't want it, but wanted to see if these Xingchen Crystals could be compressed again, from an eighth-order material to a ninth-order material, although this hope was very slim.

In the lower realm below the immortal realm, ninth-order materials are already the highest level of quality, and generally speaking, ninth-order materials are numerous, so they are rare and precious, and it is impossible to appear in batches, otherwise wouldn't it be cabbage?

That is, because of Lin Feng's system store, he can sell ninth-order materials indefinitely, in this regard, the disciples of Fengwu Sect have already taken a great advantage, ninth-order materials are expensive, expensive is certain, in many cases, even if you have resources, you can't exchange them for ninth-order materials.

People who cultivate immortals live for a long time, and tens of thousands of years of bigwigs abound, but even these bigwigs don't dare to say that they can definitely get together a clone that uses ninth-order materials to refine, if they know where this kind of material is sold, they have to buy it if they go bankrupt, even if they can't get it, they can still use it for future generations and grandchildren, and ninth-order materials are suitable for heirlooms.

The white dwarf continues to collapse, causing increasing pressure.

Lin Feng was already feeling the pressure, he sat down cross-legged, and the Immortal Emperor's body kept moving, resisting the pressure around him.

In the end, it is said that the pressure per square centimeter is one billion times that of the earth, there is such a terrifying legend, Lin Feng does not dare to ignore it, not to mention that there are still star crystals, no matter what, Lin Feng will definitely resist to the end.

Between the arrival of the forest wind, the area of the white dwarf is larger than that of the earth, but after the appearance of the star crystal, the area of the white dwarf is only half of the earth.

Star crystals appeared one after another, and in addition to star crystals, other things on the white dwarf star also became a hard substance, which should be some kind of peculiar rock, of course, the hardness of this rock has long exceeded the so-called diamond.

Lin Feng looked at the starry sky outside the white dwarf, countless rays of light submerged into the white dwarf, and then did not spread, the strong gravitational pull of the white dwarf absorbed all the light.

At this time, Lin Feng suddenly had an inexplicable idea.

"Ash, you said that if someone created an exercise with this phenomenon caused by the white dwarf, it should also be extremely powerful, right?"

"In the Nether, it should be considered top-notch. ”

"What about neutron stars?"

"The principle of the formation of neutron stars and white dwarfs is actually the same, but the effect is different, that is, the limit compression, because of the strong gravitational force, but this gravitational force is not painful for the immortals at all, and there are many exercises in the nether realm that are far stronger than this gravitational force. ”

"What about black holes?"

"Black holes involve some kind of space-time rules, and the host can treat the black hole as a moving spatial rift. ”

"Doesn't that feel powerful?"

"Yes, this natural phenomenon is really not powerful, there is no need for the host to be envious, let alone immortals, even if it is a powerful Ascension Realm cultivator, with a punch in his hand, he can form a black hole. ”

"Uh, I suddenly remembered, there are stars in the fairy world, right?"

"Yes. ”

"Then the planets of the fairy world will also form white dwarfs, neutron stars and black holes?"

"This news requires immortal jade, whether the host pays..."

"Damn, you're telling me about money at this time?"

"The news of the fairy world is of course valuable to the host now, so what's so strange about asking for money. ”

", I don't want to know. ”

"Okay, please feel free to call Ash if the host needs it. Ash snapped.

Coming back to his senses, Lin Feng picked up the Xingchen Crystal on the ground, it was still an eighth-order material, he sighed, he was not greedy, and directly sold the Xingchen Crystal to the system.

The current white dwarf has almost shrunk to the size of an ocean on the earth, Lin Feng stood up, stepped forward step by step, and quickly picked up the crystals formed on the ground.

Xingchen Crystal can also be used to refine clones, and the effect is also quite good, because Xingchen Crystal is a highly compressed material, extremely heavy, and extremely hard, although the effect of refining earth attribute clones is a little worse than that of the Heart of the Earth, but among the eighth-order materials, it can be regarded as a relatively top batch.

Under tremendous pressure, Lin Feng picked up all the star crystals on the surface of the white dwarf, looking at the skyrocketing spirit jade, Lin Feng was happy, this trip was really worth it, and he picked up a lot of wealth that he couldn't earn in a lifetime.

Then Lin Feng fell asleep on the mountain peak in front of him, this mountain peak also seemed to have turned into a star crystal, Lin Feng's primordial spirit was compressed by gravity, and it couldn't be detected far, but just the detection range was enough to make Lin Feng's heart bloom.

"It's formed, it's really formed a star crystal. ”

Seeing that the mountain peak formed a star crystal under tremendous pressure, Lin Feng pounced on it, knocked this star crystal mountain open, and sold it to the system piece by piece.

Cool, it's so cool, this feeling Lin Feng hasn't experienced for a long time, although he got a lot of good things in the body of the Martial Demon Venerable last time, but how dangerous it is in the body of the Martial Demon Venerable, I am always frightened, which is like now, easy and pleasant.

But now, the gravitational pull of the white dwarf star has become quite terrifying, and Lin Feng's immortal emperor body is also a little unbearable, he can only sacrifice the earth tripod, the earth tripod keeps rotating behind his head, sprinkling bursts of earthy yellow light, protecting the body, and the pressure is suddenly reduced.

Lin Feng stayed on the white dwarf for nearly a month, and the white dwarf finally stopped shrinking, and the final white dwarf was very small, about the size of a football field.

The quality of the formed white dwarf is too high, although Lin Feng has the earth tripod body, it is very difficult to take a step, the strong density and gravity of the white dwarf star are similar to the body of the Martial Demon Venerable, but it is a pity that the white dwarf star cannot form a unique space like the body of the Martial Demon Venerable, creating countless strange creatures.

After all the Xingchen Crystals were harvested, Lin Feng had no reason to stay, and directly used the ability to return to the sect and returned to the sect.
