Xiao Yu once received two lives from the solar system. Now, Xiao Yu hopes to get a third life from the solar system. This is really important to Xiao Yu. It's a huge puzzle, and the key to solving it may be hidden in the solar system.

Xiao Yu did not adopt the method of long-range observation, but manipulated his observation fleet to slowly approach the solar system in a conventional way. The first thing that Xiao Yu crossed was the Oort cloud in the solar system.

Oort Cloud was as empty and silent as ever, and there was basically no difference between it and the rest of the universe. But through the telescope, Xiao Yu could perceive that there were countless asteroids, and the debris was scattered in this long void. There was no observation value here, so Xiao Yu directly crossed over here and continued to set off towards the inner solar system.

Xiao Yu only used an observation instrument equivalent to human naked eyesight to look at the faint star in the distance. At this distance, the Sun is just a star, a little brighter, but no different from the rest of the stars in the celestial sphere. It's just a dot-like structure, and with human eyesight, it's hard to see any detail on it.

Xiao Yu's fleet continued to advance, and after more than a year, Xiao Yu reached the first outer planet of the solar system, the Lost Star.

After adjusting the direction of the voyage, Xiao Yu's exploration fleet successfully entered the orbit of the Lost Star, and sent a landing force to the Lost Star for further exploration.

The Lost Star remained silent, and it seemed that endless time had not brought any change to it. There is still hydrogen that has been frozen into a solid. Methane, dry ice, water, etc. accumulate on top of it. There was a strange glow in the light of the detection robot's illumination. It was pitch black, cold, and filled with an aura of ancient savagery that filled all near-Earth space.

The Earth Near-Earth Detection Robot did not find any anomalies above, but in the orbit, the detection equipment with a wider field of view found a little anomaly. Xiao Yu realized that compared to the last time he had not yet destroyed the Sweeper civilization, the detection data of the Lost Star. The crater above the Lost Star is about three percent less than that, and several of the giant dry ice glaciers that are slowly moving have receded a bit.

What this means. Xiao Yu knew it very well in his heart. This does not bode well. Xiao Yu's mood was a little heavier for no reason.

Xiao Yu's fleet continued to move forward, and after crossing the orbit of the Lost Star, it entered the Kuiper Belt. Strictly speaking, Pluto also belongs to the Kuiper Belt and is not really a large planet. Because it does not have the ability to empty the rest of the celestial bodies in its own orbit. Ceres, Marriage, Xena. Sedna and other stars are in the Kuiper Belt.

Xiao Yu's exploration fleet visited these planets one by one, but nothing came of it. The scientific research value of these stars is not too great, so even Xiao Yu in the past did not spend much energy on these stars.

After crossing these planets, Xiao Yu's fleet reached the first truly large planet in the solar system, Neptune. Neptune is a vast planetary system with many large and small moons orbiting the planet. Xiao Yu has a lot more understanding of Neptune. After fully exploring Neptune, Xiao Yu's mood sank a little again.

There is not much difference between the data that Neptune and Xiao Yu have explored before. In fact, millions of years is not too long for the evolution of stars. Even Neptune has also gone back in time, and millions of years are not enough time for Neptune to change much. But it's a subtle change. It was enough for Xiao Yu to notice.

For example, one of Neptune's moons is constantly pulled by Neptune's gravitational pull, and its geological structure has shown some signs of instability, with volcanoes, earthquakes, and orogeny on it. The red-hot underground magma gushed out and melted the dry and water ice on top of it, causing something resembling a fountain to appear on it.

After measurements, Xiao Yu confirmed that the geological activity of this satellite was reduced by a few tenths of a percentage point compared with before. This means that there is also some reversal of time on it. Its instability has slowly increased over time, and now that it has become a little more stable, it naturally means that time has been reversed. And the degree of its geological activity is completely consistent with Xiao Yu's speculation.

In addition to these things, Xiao Yu also found that on the rest of the moons, the number of meteorite impact craters was a little less, and the huge cyclone on Neptune was also returning to its position at a normal speed millions of years ago according to his own speculative data.

Again, this does not bode well.

"It has been confirmed that time has been reversed in the galaxy." Xiao Yu thought silently. The discovery in the solar system completely broke the last bit of luck in Xiao Yu's heart. Now Xiao Yu's hope is only one thing, that is, even if time really goes back, there are primitive apes on the earth. As long as there are primitive apes, Xiao Yu can prove that he really existed here.

Two and a half million years ago, primitive ape man had appeared on the earth, and according to the geographical division, there were Yuanmou man, Lantian man, Peking man, Javanese Homo erectus, etc. It was a time of mammoths and saber-toothed tigers. At that time, though, ancient humans had already shown their own peculiarities. They chose to walk upright and mastered fire and simple stone tools.

Primitive apes were not really humans, but they were not genetically different from modern humans. As long as they exist, Xiao Yu can prove what he wants to understand.

With a little trepidation, Xiao Yu's fleet continued to move forward. After passing Neptune, there is the orbit of Uranus. However, at this moment, Uranus is on the other side of the sun, so Xiao Yu did not explore it, but changed his orbit slightly and headed towards Saturn's orbit.

Saturn's moon, Titan, is Xiao Yu's second important exploration target in addition to Earth. This is almost equivalent to Xiao Yu's second hometown. At the beginning, Xiao Yu used Titan as a pedal to evolve from interplanetary navigation to the stage of interstellar travel.

Xiao Yu's spacecraft successfully entered the orbit of Titan and landed on it. In front of Xiao Yu, there was a slightly dark sea. There are also tides on Titan, and the waves are constantly lapping against the shore, and the sound is transmitted through the dense air above Titan to the sound-sensing equipment of the detection robot.

Titan has never changed. Here, Xiao Yu sent out the predetermined activation key of the Titan base, but after waiting for a while, Xiao Yu did not receive any response.

As Xiao Yu expected, all the bases he once built on Titan, all the buildings disappeared. Xiao Yu arrived at Titan's Shangdu District, but the Shangdu District was just a flat open space, extremely empty. There were only a few small lakes made of liquid methane lying silently, and there was no sign of anyone ever setting foot in them.

Xiao Yu was not willing to leave, but set his sights on those huge methane lakes and methane oceans. After successfully creating several heat sources, the scene Xiao Yu was looking forward to appeared.

It was a large dense influx of black bugs. Endless black bugs crawled out of the methane lake and desperately crawled towards the heat.

"This is the ...... of black worms" After catching some black bugs for detailed analysis, Xiao Yu confirmed this. This is undoubtedly the black worm that he has encountered, captured, and used their corpses to create spaceships.

This is the first creature to face the number in Xiao Yu's memory. By now, Xiao Yu's spirit has finally lifted a little.

There was also a clear time lapse on Titan, but the existence of these black insects is obviously not only 2.5 million years. So, even though time has been turned back for so long, these black bugs still exist.

After leaving a portion of the probe instrument on Titan, Xiao Yu's exploration fleet continued to move forward and reached the orbit of Jupiter. As Xiao Yu expected, among Jupiter, there was no one of the primordial ghost clans, wood spirits.

Beyond Jupiter's orbit is the asteroid belt, and beyond the asteroid belt is Mars. The current Mars is a little different from the Mars in Xiao Yu's memory, all the craters caused by the massive meteorite impact caused by the explosion of the earth have disappeared from Mars, and the phenomenon of the atmosphere being stripped due to the collision of the wood and the moon has also disappeared. Now Mars seems to have recoiled, returning to its original appearance.

Beyond Mars, it is Xiao Yu's hometown, the earth.

Xiao Yu's mood was also tense to the extreme at this moment. The earth is still as pale blue as before, with some white in between, but not much green.

Xiao Yu's heart sank slightly. Xiao Yu knew very well that the blue was the seawater, and the white was glaciers.

There is no doubt that the Earth has regressed to the Ice Age.

Although Xiao Yu was disappointed by this, Xiao Yu was always mentally prepared, but he did not have much psychological fluctuations. After checking the general condition of the earth, Xiao Yu sent his own landing force.

"It doesn't matter if it's a Beijinger, a Yuanmou, or a Lantian person, it doesn't matter if you're a Homo erectus, as long as I can find the ancient ......ancestors of mankind here," Xiao Yu prayed silently in his heart. (To be continued......)
