This is a long-dead star system, although it has not been completely destroyed, but all the planets in the star system, including the main-sequence stars, were "dead" millions of years ago, that is, they lost their life force. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 Fortunately, the planet that the Skyfire Eagle was guarding is still there.

Actually, it's a very common galaxy.

The main-sequence star is a third-generation star, i.e., in its third life cycle before it is destroyed. Although it was a huge star much more recently, it threw a lot of material out after the first two life cycles, especially the two Big Bangs. Because of the limited amount of matter that can be preserved and regrouped, the main-sequence star degenerates into a much smaller yellow dwarf star during the third life cycle. Of course, it was the two Big Bangs that caused a large amount of material to escape from the main-sequence star, and it did not become a celestial object in the star system that could not escape the gravitational constraint of the main-sequence star. More importantly, the high temperature and pressure generated by these two big bangs turned a large number of light elements into heavy elements, which eventually became mineral resources stored in various celestial bodies.

It's just that this galaxy is too young.

While the first two life cycles, especially the second lifecycle, lasted billions of years, the third life cycle has just begun. At least for this galaxy, which has been stable for tens of billions of years, the next 100 million years can only be regarded as the beginning of life. In this short period of 100 million years, although the matter scattered in the star system has coalesced together and become planets, almost all planets are in the nascent stage, that is, the geological activity is so frequent that even the most adaptable silicon beasts cannot survive. It is precisely because of this that for a long time, there was no life in this star system, and it was not taken seriously.

It can be said that if it weren't for the fact that it happened to be at the junction of the realm of the Hundred Horned Dragon and the Skyfire Eagle, and there was no more suitable star system nearby, this star system would definitely not have been chosen by the Skyfire Eagle. In fact, only the Heavenly Fire Eagle can survive here, that is, the Heavenly Fire Eagle has the superpower to control internal energy, and it can also survive in higher temperatures. If it were other silicon beasts, I am afraid that they would not have set up camp here at all.

Of course, this was millions of years ago.

Now, entire star systems are dead. Because of the loss of too much mass, the main-sequence star has stopped burning, i.e., there is not enough mass to generate strong pressure to keep the nuclear fusion inside going, and it has collapsed into a "death star" with no light and may be able to exist forever until the destruction of the universe. As for the other celestial bodies in the star system, because they have lost the gravitational restraint of the main sequence star, most of the outer celestial bodies have escaped from the star system and become lone stars wandering around in the universe, while those who have not escaped are also shrouded in darkness because they cannot obtain the light and heat from the main sequence star. Without external influences, these planets would have existed for billions, if not tens of billions of years, without the slightest change because they are extremely cold and have surfaces close to absolute zero.

Apparently, no living thing has visited this place for millions of years.

As for the planet that was chosen by the Skyfire Eagle to build a military fortress on it, the situation is similar, and even worse.

This planet has long been shattered, and part of it, about one-tenth of the total number of planets, has been missing. However, the most lethal loss is in the interior of the planet, that is, the planet loses its core, which loses most of its mass, and can no longer rely on its own gravity to recover the fragmented parts.

It's just that the planet is only shattered, not completely collapsed.

The main thing is that the planet already has a large mass, and even if it loses its core, the remaining mass can produce a strong enough gravitational pull.

What's more, the planet's shell has been largely preserved.

When he came to the vicinity of the planet, Yang Yi first saw the fortress, which was a ruined wall to be precise.

Obviously, that was the fortress of the Skyfire Eagle, and it was the place where the Skyfire Eagle fought for the last time.

Because of its innate ability to control internal energy and create extremely high temperatures, the Skyfire Eagle does not build military fortresses by means of construction, but uses local materials. To be precise, it is to melt the rock and make use of the natural topography to construct a solid facility.

In fact, the Skyfire Eagle lives in a natural cave, not much different from other silicon beasts. It's just that the caves of the Skyfire Eagle are generally on cliffs, that is, places that are difficult for other silicon beasts to reach. The key is that the Skyfire Eagle is able to fly, and its daily activities are not limited by the terrain.

Because it has been destroyed, the planet's atmosphere disappeared millions of years ago.

Actually, that's a good thing.

Without the atmosphere, there is no weathering problem, and the main-sequence stars are dead, so there is no problem of being destroyed by stellar storms, plus the low temperature is close to absolute zero, so as long as it is not hit by meteorites that occasionally collide, the objects on the surface of the planet can survive for a long time and will not change much. It is clear that the destroyed fortress still has the same appearance as it was millions of years ago.

Not just the fortress, but also the corpses of some Skyfire Eagles.

It's just that if you don't look closely, you won't be able to find it at all.

Don't forget, Skyfire Eagle is also a silicon beast, although it is a royal silicon beast, but it is not fundamentally different from ordinary silicon beasts in terms of body structure, that is, Skyfire Eagle's body is still composed of silicide. In other words, after death, the corpse of the Skyfire Eagle will solidify into rock due to the decrease in temperature.

Inside and outside the fortress, there were corpses of Skyfire Eagles everywhere, and many of them were mutilated.

Obviously, all of the Fire Eagles have died tragically these days, even when they are killed in battle, they have faced strong enemies. It's a pity that the enemy is too strong. Even if thousands of Heavenly Fire Eagles were not afraid of death and fought bravely to the last moment, they could not change the outcome of this battle.

Yang Yi did not enter the fortress, but walked towards the outside of the fortress.

The Dragon Empress was puzzled, but she followed suit. In her opinion, if the sacred relics of the Heavenly Fire Eagle were hidden here, they must be inside the fortress.

After walking for a while, Yang Yi stopped.

"What did you find?"

"It should be the Divine Emperor who killed these Heavenly Fire Eagles," Yang Yi let out a long breath before he said, "Moreover, the Divine Emperor should have been standing here at that time, and he only used one move to kill all the Heavenly Fire Eagles in front of him." Although the Heavenly Fire Eagle is a royal silicon beast, and there are many of them, they can't even stop the God Emperor's move. ”

The Dragon God Empress was slightly stunned, and only after noticing Yang Yi's gaze did she look back.

With just one glance, the Dragon God Empress understood.

Behind them, there were the corpses of the Skyfire Eagle, all facing where they were standing, and all of them were in battle appearances.

"Obviously, even millions of years ago, the God Emperor was extremely powerful, perhaps no worse than now." Yang Yi glanced at the Dragon God Empress before saying, "You must know that the individual strength of the Heavenly Fire Eagle is no worse than that of other royal silicon beasts. With so many Heavenly Fire Eagles, even I can't guarantee that I will be able to kill them all with one move. The God Emperor was able to do it, and if you look closely, those Heavenly Fire Eagles who died in battle didn't even have a chance to make a move. ”

"So what? The God Emperor is already very powerful, otherwise we wouldn't have come here to find a way to defeat him. ”

Yang Yi smiled reluctantly and said, "That's true, but we have to clearly understand that even if we find a way, we may not be able to defeat the God Emperor smoothly." ”

"Anyway, we have to find the sacred relics of the Heavenly Fire Eagle first."

Yang Yi nodded, didn't say anything more, and headed towards the fortress.

The Dragon Empress sighed and immediately followed. Actually, she knew Yang Yi's thoughts very well. After coming to this ancient battlefield, Yang Yi was obviously afraid of the strength of the God Emperor, and even became less confident because of it. But now, all that is needed is self-confidence. If you don't even have self-confidence, then even if you find the Holy Relic of the Heavenly Fire Eagle, you may not be able to use it, let alone defeat the God Emperor.

Of course, the Dragon God Empress also knew that Yang Yi would not be discouraged by this, because Yang Yi was a person who did not admit defeat.

Even if the God Emperor was stronger than they knew, it could only stimulate Yang Yi's fighting spirit and make Yang Yi try his best to find a way to make himself stronger.

After a short time, the two came to the inside of the fortress.

After discovering the passage that led straight to the center of the earth, Yang Yi and the Dragon God Empress were surprised, but then they both thought of the origin of this passage.

The two didn't waste time inside the fortress, and there was nothing to explore.

As on the outside, the inside of the fort was full of the corpses of the Heavenly Fire Eagle, and they were all killed by the enemy during the battle, and the situation was similar to the outside, that is, there was only one enemy of the Heavenly Fire Eagle these days, and it was extremely powerful. All of the Skyfire Eagles that died in battle faced the same place, a route to be exact. It was clear that the Fire Eagle was holding back that powerful enemy these days, and the enemy's direction was the entrance to that passage.

Coming to the top of the passage, Yang Yi and the Dragon God Empress immediately affirmed the judgment they had made before.

This passage leads to the center of the earth, but the center of the earth no longer exists.

"Go in?"

Yang Yi nodded slightly and said, "Don't worry, we're already here anyway." Don't you think this passage is a bit strange? ”

"Strange?"

"Obviously, when the God Emperor came in, the Skyfire Eagle inside the fortress was all engaged in battle, and it was only to stop him from advancing here. In other words, when the God Emperor arrived, this passage already existed, and it was very important, otherwise those Heavenly Fire Eagles would not have fought to the death. ”

"You mean ......"

"This passage is the masterpiece of the Heavenly Fire Eagle, and it has nothing to do with the God Emperor. Perhaps, the God Emperor personally went out to horse, which is also related to this passage. ”

The Dragon God Empress frowned, obviously not figuring out what Yang Yi meant.

"The point is, why did the Skyfire Eagle make a passage to the center of the earth? Obviously, this passage is not used to deal with the enemy, and it will not help to defend the planet in the slightest, but it will cause a catastrophe or even lead to the destruction of the planet. If there was no particularly important purpose, the Skyfire Eagle would not do such a thing. ”

"Perishing with the enemy?"

"Destroy the enemy by destroying the planet? If you are only dealing with the Silicon Charm army, this trick will still work, but if you want to deal with the God Emperor, it is obviously impossible. ”

The Dragon God Empress was slightly stunned, and then she suddenly understood what Yang Yi meant. (To be continued.) )
