Chapter 401: Star Soul Remains and Dark Shadows Blocking the Road!
The magnificent giant that Su Yu transformed into turned into a stream of light at a speed thousands times faster than the speed of sound and rushed out of the orbit of the planet.

He turned his head to look at the dark planet, then accelerated again and flew towards the depths of darkness.

His target is the Ruins Star!
In other words, the original orbit of the Ruins Star.

In this time and space, the Ruins Star has been destroyed by a war.

But Su Yu suspected that this destruction was not complete and there were some remnants.

The star at the center of the galaxy was also destroyed and disappeared, but its gravity still remained, which clearly meant it was not completely destroyed.

Su Yu felt that the Ruins Star was the same, with some remnants left.

And the remaining part should be a channel to return to normal time and space.

Su Yu flew all the way and soon accelerated his speed to ten thousand times the speed of sound.

While flying, he was also calculating in his mind the orbital data of the Ruins Star.

If Su Yu guessed correctly, the remnants of the ruins star after its destruction were still running on its original orbit.

As long as we search along the track, we can find the remnants.

However, the orbit of a planet is too long. According to Su Yu's calculations, the circumference of the orbit of the Ruins Star is as long as 1.3 billion kilometers.

In addition, after the destruction of the ruins star, its remaining parts may not strictly follow the original orbit, and there will be certain errors.

This way, I have no idea how long it is.

The main ruins star was destroyed so thoroughly that it even had no gravity. Otherwise, Su Yu would have followed the source of gravity to find it long ago.

Now we can only search like looking for a needle in a haystack.

Fortunately, Su Yu has enough patience.

In this way, Su Yu flew for more than 2 billion kilometers in the dark vacuum of the universe. Finally, he sensed something strange in the dark vacuum ahead.

"Is this...planetary energy?"

Su Yu's heart moved.

He was sure that this slight abnormality was the fluctuation of the planet's energy!

Before Su Yu became a time mechanic, he had been borrowing planetary energy in order to travel through time and space.

At this time, he had a very deep understanding of planetary energy and his perception was very keen.

So with just a slight fluctuation, he could be sure that there was planetary energy ahead!
This kind of energy is completely different from the energy of a supernatural being. It is very heavy. Su Yu will definitely not make a mistake.

However, there is no gravitational fluctuation in front, and there is no planet, so where does the planetary energy come from?
Su Yu was delighted, knowing that he had finally found it!

He flew forward millions of kilometers, and the feeling became stronger and stronger.

Finally, he suddenly slowed down and slowly stopped.

He stood quietly in the dark void, looking at the darkness before him, and muttered to himself:

"Is this what's left of the Ruins Planet?"

In the darkness before my eyes, there was nothing but thin cosmic dust.

But Su Yu switched his perspective and replaced vision with the perception of the planet's energy.

Then Su Yu "saw" a "planet" made up of planetary energy slowly rotating in front of his eyes.

This "planet" gave Su Yu a very familiar feeling, it was the Ruins Planet!

It turns out that although the Ruins Star was destroyed, the planet's energy remained and was still running in orbit.

Just like in some weird legends, when a human dies, his soul remains and becomes a ghost.

What Su Yu was facing at this time was the "Star Soul" after the destruction of the Ruins Star.

“It seems that as long as I use this star soul and resonate with the ruined star in normal time and space, I can achieve cross-time and space travel and return to normal time and space!”

The moment Su Yu saw this "Star Soul", he thought of a way to return.

It is estimated that the Ghost Emperor used this method to send Su Yu here.

Su Yu looked into the distance again. That was the largest source of gravity in this dark space and time: the sun!

There is only darkness there, no matter, but there is gravity coming from it.

So, the sun may also have some residual planetary energy? Even its gravity remains.

Su Yu thought about it and flew directly towards the source of the sun's gravity.

Anyway, he has now determined the location of the ruins star soul, so there is no rush. He will go to the sun first to take a look.

Before, Su Yu was always worried that there might be some danger on the other side of the sun, so he didn't go to check it out.

Now that I'm working as a time mechanic, and I've figured out some of the remaining secrets on the planet, I have the confidence to go and take a look.

After all, I will be returning soon. If I don’t watch it now, I may not have the chance in the future.

Su Yu flew all the way and flew hundreds of millions of kilometers, and finally felt a huge source of gravity right in front of him. This was his destination.

However, Su Yu only felt the source of gravity but did not sense the energy of the planet.

"Could it be that the sun has no planetary energy, only gravity?"

Su Yu was confused and looked at it carefully, but still couldn't figure out the principle.

However, he had a little surprise.

That is, he discovered some special "substance" in this dark vacuum.

In fact, it didn't seem to be matter, nor was it subspace energy, nor was it data.

These things cannot be seen or touched.

The reason why Su Yu was able to discover them was because he tried to open the material space and wanted to collect some cosmic dust in this area for research.

As a result, I put some of those things in.

Then Su Yu discovered that there was abnormal gravity in the materialized space.

"So this is where the gravity source in this area comes from!"

Only then did Su Yu understand the source of the gravity here.

After the sun was destroyed, some invisible and intangible things remained.

Even if Su Yu is a fourth-level strongman, he cannot sense the existence of such things.

However, they have gravity and can be collected by the materialized space.

"Is this... dark matter or dark energy?"

Su Yu thought for a while and said to himself.

The so-called dark matter is a large amount of invisible gravitational sources in the universe that scientists have calculated.

They do not emit light, but only emit gravity, maintaining the stability of galaxies and even the entire universe.

These things are collectively called dark matter and dark energy.

Before Su Yu traveled through time, he already had some understanding of dark matter and dark energy.

At that time, these things were still unsolved mysteries to Su Yu.

Of course, after he traveled through time, this was no longer an unsolved mystery.

Especially after coming into contact with the Mechanical God, Su Yu gained a lot of knowledge and learned the truth about dark matter and dark energy.

There are many strange forms of matter and energy in the universe, all of which can be called dark matter and dark energy.

They are a general term for a category of strange and varied kinds, and even the Mechanical God doesn't know how many types there are.

Just like humans, radioactive beasts, and cosmic aliens, they are all considered life, but the differences between them are huge.

Even if Su Yu possessed the ability to pull gravity, and flew into the vacuum of the universe, hiding his body and releasing gravity, Su Yu himself could be considered dark matter.

At this time, the things Su Yu collected here are also a kind of dark matter.

Su Yu recalled that even in the knowledge passed down by the Mechanical God, there was no relevant data on this kind of dark matter.

I don't know how it was formed.

It is estimated that the formation of this dark matter involves the participation of subspace, so the Mechanical God has never seen this thing. This strange dark matter must have a high research value.

Many of Mechanical God's technologies require the use of various dark matter and dark energy.

Su Yu was previously unable to obtain the material energy in the deep space of the universe, and many of the Mechanical God’s technologies could not be used at all.

Now that he has discovered this new dark matter, he naturally will not let it go.

Su Yu quickly created a new material space and began to collect the dark matter here.

Su Yu's embodiment mechanic can create multiple embodiment spaces. Different spaces are independent of each other and do not interfere with each other.

Of course, the more materialized space Su Yu maintains, the greater his consumption will be.

But there is no way. In one of Su Yu's materialized spaces, there are also Galaxy Warriors and others. They cannot be mixed together, otherwise people might die.

Su Yu's collection took several months, and only when he filled up the newly opened material space did he finish.

However, this dark matter is too strange. It has gravity but no inertia and mass.

In the end, Su Yu didn't know how much he had collected.

It can only be calculated based on the strength of gravity, which is about one third of the Ruins Star.

In other words, if this dark matter has mass, its mass is one-third of that of the ruins star.

This is amazing. Su Yu's collection is equivalent to collecting one-third of the dark matter of the ruins star.

Among the planets, the Ruins Star actually has a large mass. Even if it is only one-third of the mass, it can be considered a standard planet.

Su Yu's collection is equivalent to directly collecting a planet!
If this dark matter was not invisible and intangible, and had no volume or mass at all, Su Yu would not have been able to collect so much.

Finally, the materialized space could no longer bear the pressure and showed signs of collapse under the pressure of gravity, so Su Yu stopped collecting.

His embodiment mechanic is still level three.

Although his body was promoted to the fourth level, the ability of the embodied mechanic has become much stronger, but it also has its limits, and this is the limit now.

And this amount of dark matter is just a drop in the bucket compared to the total amount here.

The mass of the sun at the center of this galaxy is hundreds of thousands of times that of the Ruins Star. If all of it were converted into dark matter, even ten thousand Su Yus would not be able to collect it all.

"That's all we can do for the time being."

"I don't know what it's useful for, but the mass of a planet will always be useful."

Su Yu finished collecting and was satisfied.

These dark matter are actually not harmful to Su Yu himself.

Its gravity is only one-third of that of the Ruins Star, and it is difficult for ordinary people to hurt it.

But this thing is actually very scary in some ways.

If these dark matter were released on the ruins planet, such a huge gravitational source would suddenly appear and might even tear the ruins planet apart.

And this is just the crudest usage.

If further research is conducted, it may be possible to make further use of these dark matter, such as concentrating its gravity, which will certainly have even more terrifying power. This remains to be studied.

This time, it can be said to be an unexpected surprise and the harvest is huge!
After completing the collection, Su Yu did not stay for long and turned to fly towards the orbit of the ruined star soul.

In a few months, the star soul had traveled a long way in its orbit, but the entire orbit had already been calculated by Su Yu. With a little thought, he could accurately locate it, so it was not difficult to find.

He quickly returned to where the Star Soul was.

Looking at the star soul in front of him, Su Yu began to think about how to use this star soul to return to normal time and space.

In fact, it is not difficult. According to previous experience, just place 30 mechanical towers on the Star Soul and use the energy resonance of the planet.

Su Yu had done this kind of thing many times before.

However, there is a difficulty now.

That is, Su Yu's previous time-travel experiment was conducted with the help of Nono's fusion and enhancement ability, which enabled him to strengthen those mechanical towers to the fourth level and realize the time-travel function.

Anyway, we are in the same time and space, so even if we travel through time, we don’t have to worry about Nuonuo getting lost.

Now we have to travel across time and space.

If Nono uses it to fuse and strengthen those mechanical towers, it will remain here when you travel through time and cannot be taken back.

Nuo Nuo has always been a good helper to Su Yu, and he doesn't want to abandon her.

"So... this is the only way!"

After Su Yu thought about it, he decided not to use Nuonuo anymore.

He wants to directly build a fourth-order energy tower!
Anyway, as a fourth-level mechanic, he has the ability to create fourth-level mechanical creations.

However, compared to the third-order mechanical creations, the fourth-order is naturally much more difficult.

Su Yu did it right away. He quickly put out various materials and started to forge.

Su Yu had built this mechanical energy tower tens of millions of times in the cycle of history and was very familiar with it.

However, this is the first time that a fourth-level one has been built.

It took more than ten days to finally complete it.

"It finally worked."

Su Yu looked at the mechanical energy tower in front of him, emitting the fourth-order fluctuations, and felt joy in his heart.

Originally he was worried that this energy tower could not become level four.

The fourth level requires sharing his subspace domain to be completed.

Now in this dark space and time, his perception of the subspace field is very weak. It is simple to create a third-order mechanical creature through a shared field. Su Yu has tried it many times before.

It would be a bit difficult to create the fourth level now.

If sharing doesn't work, it fails.

Fortunately, it succeeded in the end.

However, only one was successful!
With Su Yu's current perception of the subspace field, he is unable to create more fourth-level energy towers.

It is impossible to activate 30 energy towers at the same time like before.

"It seems that I can only use my own time power."

Su Yu was not discouraged, as this was within his expectations.

If one energy tower is not enough, then use your own time power to make up for it.

Although there will be backlash, it will be much weaker because the energy tower will bear it, and it should not be too dangerous.

"Then let's get started!"

Su Yu stretched out his hand, grabbed the newly built fourth-level energy tower, and flew towards Star Soul.

This energy tower is a hundred meters high, but in Su Yu's hand, it looks like a chopstick.

He flew all the way and soon arrived at the center of the star soul, which is the gathering point of all the energy of the planet, equivalent to the core of the star.

On the surface, Su Yu was actually quietly floating in the dark vacuum. Only he himself knew that he was in the depths of the Star Soul.

Then, he waited quietly, waiting for the energy fluctuations of the Star Soul.

After waiting for more than half a year, Su Yu finally witnessed a violent fluctuation of planetary energy!

"start!"

Su Yu did not hesitate and immediately activated the fourth-level energy tower he had built earlier!
Then, the power of time in his body was madly poured into the energy tower to strengthen its power!
boom!
In an instant, Su Yu's consciousness, with the help of the resonance of the planet's energy, penetrated time and space!

He saw the familiar ruins of the planet! As long as he thought about it, he could travel back!
However, just as Su Yu was about to complete the crossing, a dark shadow blocked his way.

"finally come!"

Su Yu always had a premonition that this return trip would not be smooth and there would definitely be a fierce battle.

However, there had been no movement before, and now when he saw this black shadow, Su Yu felt like a huge stone had fallen from his heart.

"I want to see what is stopping me!"
