There is an old saying in China - close to home.

This sentence perfectly interprets the complicated feelings of the wanderer when he returns home.

At this moment, the sea of clouds is like this.

From a temporary "wormhole" on the "earth" to the "small universe" existing in an unknown star field, Yunhai doesn't know how many times he dreamed of returning to the "earth".

He even thought for a moment that he would never have a chance to return to "Earth".

This idea, after he left the "small universe", was confirmed with certainty.

In the star field that can be explored, there is no "Milky Way" at all, and at that time, the "mastermind" of the "intelligent microscopic civilization" dares to say that it can observe almost the entire universe.

The statement of "mastermind" made Yunhai completely desperate.

He even remembered the concept of the "multiverse", and the universe he was in now was not the same universe as the universe in which the "Milky Way" existed.

Without "space gates" and "wormholes", it would be an insurmountable distance for the sea of clouds to travel from one river system to another.

Spatial transitions are not infinitely possible.

Every time the space jumps, the sea of clouds and the moon consume a certain amount of energy.

And in the intergalactic medium region between the river systems, in that almost absolutely empty area, they simply cannot replenish their energy.

In other words, if you rush from one river system to another, the biggest problem is not being able to get energy replenishment.

This is just a big trouble between the river systems of the same universe, and if it involves the conceptual problem of the "multiverse", Yun Hai knows very well that he will not be able to solve this problem for a long period of time.

Therefore, in Yunhai's heart, returning to the "earth" is just a dream, and it may even be more unattainable than the dream of the alien civilization to defeat the "primordial alien worm" race.

He would never have expected that it was just a roundabout action, and through the ancient and mysterious "space gate", he didn't know how many river systems he crossed in an instant, or maybe he crossed the "multiverse" and returned directly to the "galaxy".

Excited and nervous.

Although Yunhai is sure that at least all the civilizations he has come into contact with, they have no intersection with the "earth".

But the world is unpredictable, and he is not sure what the current "earth" will look like, or what the people who care him will be like.

In this way, with excitement and nervousness, the sea of clouds and the moon entered the "solar system".

Extremely sensitive to environmental changes, they soon felt the light and heat radiation from the "sun".

Without hesitation, Yun Haifei began to speed up in front.

After he had been in a straight line for a moment, a beautiful planet appeared in the distance.

Saturn, the sea of clouds determined at a glance that the earthy yellow planet with its beautiful "ring system" is Saturn, one of the eight planets of the "solar system".

Finally saw the first familiar planet on the way forward, and the sea of clouds became more and more excited, and once again sped up.

When he left the "earth", the sea of clouds did not yet have the ability to fly in the universe.

And this time, he didn't plan to let go of this beautiful planet.

Following the magnificent "ring system", Saturn hung quietly on the black cosmic curtain.

It is a gas giant, and even if it shows its violent side when the sea of clouds approaches it, it is a spectacular and beautiful planet in the eyes of the sea of clouds.

did not feel the existence of any breath of life, which was also expected by the sea of clouds - if Lei Li wanted to open up a second life planet in the "solar system", then he would definitely choose Mars or the legendary "Enceladus" that is more suitable for human survival.

Of course, the sea of clouds did not let go of "Titan".

From a distance, Enceladus resembles the moons of more planets, with craters of all sizes on its surface.

When Yunhai and Yunyue approached, they saw geological formations such as trenches, cliffs, and ridges.

Moreover, they saw a lot of "ice volcanoes".

These "ice volcanoes" spew out not fiery lava, but large amounts of water vapor.

And this is also the key to the existence of life on "Titan" from a very early stage on "Earth" humans.

Although the sea of clouds has made it clear that water is not the only prerequisite for the formation of life, it is clear that planets with water are more likely to give birth to life.

After flying around Enceladus, when Yunhai was about to leave, Yunyue suddenly accelerated and fell to the surface.

The surface is a huge rift.

Yun Hai didn't know what caused it, but he could see that the width of this rift was about five to ten kilometers, and the length was more than two hundred kilometers.

Yunyue, who fell rapidly, flew down towards this rift or canyon.

Before Yunhai could hesitate to chase down, Yunyue, who had just disappeared into the canyon, jumped out again.

"The detector of the Silver Dragon Empire, the most conventional model, I should be right?"

Instantly returning to Yun Hai's side, Yun Yue's sharp claws were handed in front of him, and at the same time asked in a spiritual exchange.

Above her giant claws is a probe visibly deformed by impact.

"That's right, it's the most conventional model of the Silver Dragon Empire's probe."

Yunyue may be misremembered because of sloppiness, and Yunhai may also ignore it, but it is impossible for the two of them to be wrong at the same time, Yunhai saw this detector at the same time, but it was exactly the same as Yunyue's analysis.

"This type of probe is not designed to work in the universe for long periods of time."

"More often than not, it's just performing some simpler tasks, such as short-term exploration and research on a certain planet......"

Recalling as much as possible, Yun Hai slowly said to Yun Yue in spiritual exchange at the same time.

It's just that when he said this, he had a very bad feeling.

Resources are limited, and the materials that Lei Li brought to the "earth" are not much.

And the "earth" of the last days is obviously unlikely to enter into normal and orderly development in a very short period of time.

In other words, the most conventional probes in the "Silver Dragon Empire" are definitely precious materials in the "Earth".

Even if the probe suddenly crashes on Enceladus because of a malfunction, it must be recovered and used for the second time after trying to repair it.

"Looks like something is wrong."

Yun Yue let go of her claws as she spoke, allowing the probe to crash into the canyon on the surface.

"Let's go, don't waste time here, go back to Earth."

The appearance of the probe cast a shadow over Yunhai's excitement.

In the spiritual exchange, she said to Yunyue, and the sea of clouds took her away from the beautiful "Enceladus" and flew deeper into the "solar system" again.

Only this time, the tension of the sea of clouds is no longer the tension when it just entered the "solar system", but the real tension.
