Chapter 1002 Break Through the Mantle! Destroy Vesta!
November 2, Monday, the first day after Halloween, is also the first day that Zhang Yanhang leaves the world of Ashes. At 9:45 am, Vesta.
After arriving at the outskirts of Vesta, Zhang Yanhang briefly scanned the environment of Vesta and found that it was indeed a very classic asteroid. The outer layer was gray and bare, with nothing but rock layers, and it was also distributed
A large crater formed after the impact of a large number of meteorites.
The largest crater is located on its inner side. It is suspected that it was hit by a giant meteorite, causing the entire Vesta to become an irregular sphere, with the outer side protruding larger.
To put it more vividly, it's like being punched in the head and then growing a big bump.
Specifically speaking, the formation methods of asteroids are mainly divided into three types, the first of which is natural formation.
As for how to form naturally, it is actually the same principle as the formation of ordinary planets, except that these asteroids have become half-grown and are much smaller than normal planets, so they are called asteroids. This is also
The origin of the name of the asteroid.
The second way asteroids are formed is aggregation, that is, a large number of miscellaneous meteorites or other planetary fragments come together during the collision with each other and then slowly form an asteroid.
.
But Vesta belongs to the third type, that is, the original normal planet was smashed by people and only a core was left, so its size shrank hugely and became an asteroid.
The evidence is that the interior of Vesta is completely made of iron. The entire asteroid has an average diameter of just over 500 kilometers, but the diameter of the iron-nickel alloy ball wrapped inside it, that is, the iron-nickel star core, is as high as over 200 kilometers.
It occupies half of its diameter.
In other words, the entire Vesta is actually covered with a thin layer of rock on the outside, but the inside is entirely composed of a core and mantle composed of iron-nickel alloy and an external buffering magma layer.
This is basically perfectly consistent with the composition of an asteroid whose crust has been stripped away, leaving only its mantle and core.
As for how Vesta was stripped of its crust, we can actually roughly judge from its appearance. It should be that a huge meteorite similar to the one that destroyed the dinosaurs slammed into the outer layer of Vesta, causing Vesta to collapse.
The crust layer disintegrated, leaving only the relatively hard core of the star that barely survived, but a large crater was also created by the meteorite.
It must be mentioned that Vesta is located in a meteorite belt, and it is a fairly dense meteorite belt. Zhang Yanhang estimates that although natural meteorites may account for a large proportion of this meteorite belt, the meteorites formed by the peeled-off crust should be
It also accounts for a considerable proportion of it.
Therefore, with such sufficient evidence, it is indeed difficult for Zhang Yanhang not to judge it as an asteroid formed after the disintegration of an ordinary planet.
After briefly observing the structure of Vesta, Zhang Yanhang began to stack buffs, that is, to activate various skills such as the indestructible golden body, then use the spiritual energy blessing, and then use the magic and sky skills to expand the body to 784 meters.
, and finally used the four-piece set of giant enlargement techniques to expand the body to 864 meters.
That's right, Zhang Yanhang's current size has grown from the original 850 meters to 864 meters. If you want to ask why, it can only be said that his current growth rate is too fast, even if the teleportation just consumed
He didn't grow in size during those twenty-four minutes, but the previous time alone still allowed his maximum transformation limit to increase to the current level.
However, for the sake of the accuracy of the experiment, Zhang Yanhang canceled the eight arms and eight toes. After all, the eight arms and eight toes increased the attack speed, which easily made it impossible for him to distinguish his current basic attack speed, leading to misjudgment.
After getting ready, Zhang Yanhang swung an ordinary but powerful punch towards Vesta in front of him.
If it were normal, Zhang Yanhang believed that the moment he punched his fist, the huge sonic boom would spread wildly in all directions and envelop huge airflow to serve as a pioneer for him.
But this is space, and there is no air on Vesta itself. Therefore, Zhang Yanhang's fist hit the surface of Vesta in silence without any ripples or ripples.
This ordinary blow, which seemed to lose its special effects instantly after leaving the atmosphere, set off layers of waves on the surface rock layers as soon as it touched the surface of Vesta.
Yes, it is a real wave. The huge impact force rapidly expands on the surface of Vesta, causing the outer rock layer to be completely unable to withstand the conduction of the impact force and being directly peeled off. This causes the outer rock layer to continuously break away from the planet's surface and fly into space.
At this time, the layers of craters with different heights could not escape the fate of being destroyed, and they were peeled off from the outside of Vesta.
After the outer rock layer was broken, the black and gray basalt below was immediately exposed. Yes, it is the same basalt layer as the bottom of the earth's crust. This is also strong evidence for Zhang Yanhang's judgment that Vesta was originally a normal planet.
But unfortunately, basalt seems to be hard, but as early as the fourth level, it has no hindrance to Zhang Yanhang. When he was on the earth, Zhang Yanhang might still be restrained for fear of destroying the earth, but Vesta, he
But he just used it with all his strength without any scruples.
Under such a difference, large blocks of gray-black basalt layers, sometimes several kilometers in size, quickly fell off from the outside of Vesta like pieces of broken egg shells, and flew into the surroundings like the previous stripped rock layers under the huge kinetic energy.
meteorite belt and violent impact.
But all of this has become silent due to the vacuum environment. It is obviously an impact that contains terrifying kinetic energy, but because there is no blessing of sound, everything is just like a silent film comedy.
However, occasionally Zhang Yanhang could hear some fierce collision sounds, but these were not meteorites hitting each other, but the sounds made by meteorites and other planetary debris that had been deviated from their orbits and hit his energy shield.
As for why he can hear sounds at this time, the principle is also very simple, because vacuum does not transmit sound, but matter does, especially solid matter as the fastest medium.
When the outer rock layers and the last remaining basalt of the crust were stripped away, Vesta finally exposed its inner egg white-like magma layer. This thick layer of magma, the mantle, occupies at least a quarter of the entire Vesta.
diameter.
Zhang Yanhang once said that magma, as a non-Newtonian fluid, can be used as a buffer to effectively reduce the impact force, but there is an upper limit to the relief of the impact force. The impact force caused by Zhang Yanhang's current punch is obviously far beyond
The upper limit of what the mantle layer can alleviate.
This is like you can't just because chewing gum is a non-Newtonian fluid and put it on your face in an attempt to withstand a bullet and hit your head. That's unrealistic.
Moreover, compared with real solid matter, non-Newtonian fluids are actually more flexible than real solid matter, rather than saying that their defense power can really surpass solid matter by a lot.
Therefore, when the impact force caused by Zhang Yanhang's punch continued to be transmitted to the rear, it was no surprise that the thick magma layer of the mantle layer, which is more than 100 kilometers long, began to circle around the contact point.
Another layer of huge fiery red waves formed, quickly rushing to other directions of Vesta, or they were directly shaken and flew high into the sky.
From Zhang Yanhang's perspective, the spreading speed of these arc-like fiery red waves is a little slow, indicating that they still play a slight buffering role, but from a normal perspective, they have been almost instantly absorbed.
A huge crater measuring tens of kilometers was made.
This huge pit reaches the bottom, immediately exposing the iron-nickel star core like a big red-hot iron ball. From Zhang Yanhang's perspective, he can clearly see that the iron-nickel star core has an irregular shape, as if it were
It looked as if someone had beaten it flat, and there were many crooked cracks all over it.
Zhang Yanhang feels that the reason why the iron-nickel star core is in its current state must be because the injuries caused by the meteorite impact have not recovered yet. Well, this is not something that can be recovered naturally.
Moreover, the kinetic energy impact, which is infinitely larger than the meteorite impact, has now been transmitted to the interior of the star core, and it no longer needs to be repaired.
Different from the past, Zhang Yanhang this time in order to prevent the embarrassing situation of being unable to destroy the asteroid due to excessive impact, so this time he deliberately used the control skills given by the fighting master for a long time, and used his
The whole body's strength is accumulated in the fist and exploded concentratedly, allowing it to form a fixed-point impact (fixed-point blast).
Therefore, with the explosion of terrifying impact, a fist mark so huge that it spanned hundreds of kilometers clearly appeared on the iron-nickel star core. The next second, irregular cracks like the veins of tree roots spread all over the entire place.
Star core.
At this time, the interior of the star core suddenly fell into a strange calm, but soon, the iron-nickel star core with a diameter of more than 200 kilometers and an irregular oval shape suddenly fragmented rapidly, carrying huge kinetic energy in a terrifying
The speed exploded in all directions.
Perhaps due to the uneven density, although the entire iron-nickel star core was fragmented into hundreds of densely packed pieces, most of which were very small, Zhang Yanhang could clearly see that a fragment of the star core located at the side and rear was fortunately preserved.
It has a larger size of tens of kilometers and flies away into the distance while knocking away the meteorites blocking the way.
If nothing unexpected happened, Zhang Yanhang felt that the original Vesta might have been hit by such an inexplicably born meteorite. However, the one that hit Vesta should have been an ordinary rock meteorite, and it was definitely much smaller.
The meteorite composed of this stellar core is the highest-grade iron meteorite, and it is tens of kilometers in size. Not to mention that the original Vesta could not withstand such a hit, and even the earth could not withstand one.
After all, the meteorite that destroyed the dinosaurs was just an ordinary rock meteorite about ten kilometers in diameter.
It can be said that this huge iron meteorite formed by an iron-nickel star core of tens of kilometers in size is basically enough to destroy the entire human civilization, and if it hits the earth, the earth's crust may not disintegrate like Vesta.
, but it is definitely inevitable that a large crater like Vesta will be smashed out, causing the star to deform.
Therefore, Zhang Yanhang can only pray silently here for the planets along the way of this iron-nickel star core, hoping that it can be broken into pieces as completely as possible.
Although Vesta was shattered, the chain reaction caused by Vesta is obviously far from over. After breaking away from the star's core, Vesta's original magma layer is currently scattered in large areas in the surrounding meteorite belt.
However, because these magma layers have separated from the star core and the earth's crust as an insulation layer, they are currently rapidly cooling and hardening in the ultra-low temperature of minus 270 degrees in space, and are frosting and ashes at a speed that is almost visible to the naked eye.
That's right, magma is freezing.
After all, minus 270 degrees Celsius is indeed not something that magma, which has a temperature of only about 1,000 degrees, can withstand.
The gaseous water molecules originally contained inside it and the small amount of water originally contained in the earth's crust are currently in the ultra-low temperature environment of minus 270 degrees. It seems magical, but in fact it is very scientific, helping the magma to quickly frost and cool into magma.
rock.
Therefore, a gray-black continent floating in place, like the legendary round sky and a square earth, soon appeared in this meteorite belt.
Of course, in fact, the meteorite belt where Vesta is located is not only a meteorite belt, but also an asteroid belt. In addition to Vesta, the largest asteroid in the solar system, it also contains some other asteroids.
However, these asteroids are basically not too big. The largest ones may only be hundreds of kilometers away, and the small ones may even be only tens of kilometers away.
It is precisely because other asteroids are not too big that Zhang Yanhang chose Vesta as the target this time. From the current point of view, Vesta is both suitable and inappropriate as a target.
The suitable part is that Vesta has a pretty good diameter, but the inappropriate part is that Vesta is actually a star core disguised as an asteroid. The difficulty of destroying Vesta is actually much greater than that of an asteroid of the same size.
After all, asteroids with rock cores and asteroids with iron-nickel alloy cores are obviously not difficult to destroy at all.
In fact, asteroids like Vesta that have the three major elements of crust, mantle and core are extremely rare. Most asteroids have rock as their core, which means that the entire asteroid is just a big stone ball.
There is no magma and no star core.
Therefore, without the obstruction of magma buffering and star core, it is naturally much easier to destroy, and the asteroid that Zhang Yanhang originally expected to be destroyed was exactly the type of asteroid.
