It's just that Xuefeng missed the opportunity to meet Neptune, and Neptune at this time should have turned to the other side of the sun.

Xue Feng regrets not being able to observe Neptune, since she left Earth, she has been drawing a real cosmic star map, and the nine planets of the solar system will be recorded.

The star map exists to better determine the direction in the universe, and it is also the only way not to lose the way in the vast universe.

In order not to get lost in the universe, Yukikaze also began to learn from humans, using Behemoth's eyes comparable to human radio telescopes, and diligently observing the starry sky.

I finally understood that the most dangerous places in the universe are those areas of thin matter that span a huge span, such as between stars and stars, or between the cantilevers of the Milky Way.

The thin density of matter means that you will not be able to obtain any resources here, and you will only have to rely on the materials you carry to cross this distance, which is a place where short-lived species like humans have a lot of headaches.

Xue Feng didn't know if the supplies she was carrying would be able to support her until she completed the journey, but she still led the insect swarm towards the distant Tianyuan Si.

Originally, Yukikaze planned to travel to a star system in the nearest Proxima Centauri, but three stars exist in this star system at the same time, which means that the planetary system inside is complex and disordered.

The chaotic order of the celestial bodies made Xue Feng give up this idea and instead seek Tianyuan IV, which had a more stable celestial structure.

At least humanity has determined that there are at least two stable planets in this star system.

Compared to the unknown Proxima Centauri system on the planet, Tianyuan 4 is obviously more reassuring to Xue Feng.

Fortunately, although Xuefeng missed Neptune, Pluto, a planet that was once removed from the nine planets, was really encountered by the swarm.

It was just in the direction of the swarm, and it only needed to adjust the angle slightly to enter Pluto's gravitational ejection range, much to Yukikaze's excitement.

Because encountering Pluto means that the swarm can accelerate at once, and the higher the speed means the shorter the time to complete the trip, as if the solar system is seeing her off, so that the swarm can rush out of the solar system at a faster speed.

Xue Feng has no intention of refusing this gift, and this is an excellent opportunity to observe the surface of Pluto, how could she miss it!

The tiny planet of Pluto is like a pearl carved from ice and rock in the solar system, and the temperature of the sun has long been unable to reach this remote place, and cold is always the main theme on its surface.

Above the glacier is the cosmic space, and there is no trace of the existence of any atmosphere, and the unobstructed surface makes Xue Feng show a regretful expression.

"It seems to be a lifeless planet, it's too deserted!"

As a qualified mother, Yukikaze would prefer to see a planet rich in species, as species thought they would be able to obtain new genetic sequences that would be useful to the swarm.

But now it seems that Pluto does not have this, and Yukikaze didn't even have the idea of going up to take a look, and after the swarm circled Pluto, it fled directly from the nine planetary systems and headed for Kuiper overseas.

Covered in fine rock and ice, the Kuiper Belt is the birthplace of meteors, but it's less than Pluto.

Here, the influence of the sun on it is minimal, and the only thing that can be counted as the influence of the sun is gravity, the matter ejected by the sun simply cannot reach such a distance, and the ring-shaped discrete celestial bodies, like a group of children who have left home, will have one or two from time to time, and want to go back to their mother to see.

Without any, the swarm crossed the final ring and flew towards the outside of the Tianyang system.

At this moment, Yukikaze suddenly had an idea, she thought that the Mayan Empire, which was composed of insect swarms, should be marked with a conspicuous emblem to prove that they were from Earth.

So a nine-star alignment, with a multi-ring icon of comet's orbit, was engraved in the conspicuous place of the carapace of the head of each swarm, which would be the famous pattern of the Mayan Empire in the future, so that the whole universe remembered that there was such a strange biological civilization, from the remote star system of the universe.

It took another 200 years for the swarm to reach the area of the Orrclouds, the final boundary of the solar system, where the material of the solar system collided with the extra-system material to form a large number of comet nuclei.

But because the density of matter is very thin, Xuefeng doesn't see any comets in his way, and the temperature here is very high, but it is also too thin to affect the swarm.

Xue Feng looked back at the sun, which was not much different from other extra-stars and only one bright spot, and remembered the last time he saw the little girl next door.

"Brother Xuefeng, you can marry me after graduation!"

The pretty girl stood there, and it was false to say that Xue Feng didn't have any ideas, but the girl's family background was better than him, I don't know how many times.

In reality, Xue Feng, who had long been pressed by life and couldn't raise her head, just replied to another girl's sad words, and returned without looking back, letting her work in a company that didn't care about other things, and became a busy little employee.

As for what happened to the girl in the end, Xue Feng didn't care, and he couldn't care, because he knew that he was not worthy of the other party and should not be with the other party.

"Xiaoxian...... If you could stand in front of me once, and I'm still that stunned young human male, I'll definitely marry you......"

It's a pity that that girl has been destroyed along with the earth.

When Xuefeng fled the earth, she knew that nothing could never have happened, and she would never see the family members and the cute girl who had haunted her from now on.

"Eva, record the image and seal it in the swarm's genes forever."

Since that day, when the swarm left the last frontier of the solar system, Yukikaze hasn't done anything but shut himself up in his chamber, reminiscing about his past as a human.

The scenes of the past continue to circulate in front of her, and the negative emotions that were suppressed before erupt like the sea bursting its banks, and the fear and fear of being alone make her live in panic like a wasted person.

Fortunately, the insect swarm has Eva, and the outer material is thin so as not to interfere with the course, so that the insect swarm is not chaotic, and Eva's assistant is still capable of ordinary daily management.

I don't know how long such days have passed, anyway, Xue Feng has long had no heart to calculate the time, and it seems that even the self has begun to dissipate when he has emptied everything.

It wasn't until one day that Gou Yi forcibly broke into Yukikaze's chamber and finally brought Yukikaze back to his senses again.

"Sister, is she homesick? Don't be afraid, Gou Yi will always be by your side in the future......"

It was such an ordinary sentence that made Xue Feng wake up from his dream, and the past and the present were completely separated, becoming two completely different lives.

She cherishes the present more than in the past.

"Yes! Gou Yi is such a good boy, and Dog Er, you will always be my good sister! ”

In a word, the two puppies jumped happily, and Yukikaze joined in the jumping, and the two girls and a dog smiled like Akuya, but none of them had blue hair.

Xue Feng's heart, which was very enthusiastic about exploration, was once again ignited by Gou's warmth.

She vowed to become a qualified mother queen for the sake of the swarm for the rest of her life.
