Chapter 250 Mysterious Signal

After the advance fleet passed the last jump bridge outside the human territory, it was completely out of the human territory.

Qi Yiming's Xuefeng also crossed this symbolic boundary and truly entered the strange universe.

Qi Yiming originally thought that it would be difficult to encounter the products of human civilization after crossing this boundary, but to Qi Yiming's surprise, Xuefeng suddenly received a mysterious signal three days after passing this boundary.

What's even more strange is that only Xuefeng received this signal among the tens of thousands of warships in the advance fleet, as if the signal was directional.

The strange signal immediately aroused Qi Yiming's vigilance.

Because the content of the signal is compilable and has obvious traces of human language.

According to the measurement of the scientific officer, the source of the signal came from a strange galaxy 300 light years away.

In fact, Qi Yiming wanted to ignore this signal, but he was afraid of missing something. What if it was something left by the former human federation?

After thinking about it, Qi Yiming finally decided to make a trip.

Because the advance fleet needs to wait for the follow-up fleet to catch up at the current location.

The subsequent journey will become long and boring, and more importantly, the fleet needs to perform unified heading calibration work at this location.

After all, a full-power jump fleet will sail in the jump channel for at least one to one and a half years, which depends on the three largest giant colony ships in the fleet.

It's not that Qi Yiming doesn't want the spacecraft to stay in the jump state, but the giant spacecraft will encounter space wrinkles during the jump.

When the spacecraft encounters space wrinkles, it will automatically leave the jump channel and return to normal space in any case.

This is the law summarized by the former human federation's nearly a thousand years of space navigation.

The larger the hull, the shorter the time it encounters space wrinkles during the space jump.

Qi Yiming once asked the Academy of Sciences to roughly calculate that the three giants in the fleet will encounter space wrinkles and be forced to return to normal space after flying in the jump channel for a maximum of 400 light years, and then the jump engine will enter a long cooling state.

This cooling state is not what humans call cooling, but the energy storage chamber of the jump engine will absorb a large amount of mysterious substances during the jump process. When this substance fills the energy storage chamber of the jump engine, the next time the jump engine is started, these substances must be discharged from the energy storage chamber.

Humans have never studied the characteristics and source of this mysterious substance, but it actually affects the maximum distance of human ship jumps.

Scientists of the former Human Federation have done experiments. Even if the single mass of a spacecraft is small, the maximum distance it can fly using the jump engine is only 1,000 light years. After that, no matter how much the mass of the spacecraft is reduced, it cannot exceed this value.

Moreover, as soon as the space fold appears, no matter what state your spacecraft is in or whether the normal universe will have a fatal impact on the spacecraft, it will be blocked by the space fold and return to the normal universe.

This is very dangerous, so generally, long-distance jump voyages like this will determine the farthest range in advance, and then choose a relatively safe environment within the range, actively let the spacecraft leave the jump mode, and wait until the jump engine is cooled before continuing the next jump voyage.

Therefore, the advance fleet will wait for the follow-up fleet to catch up at the current location, and then the entire fleet will calibrate the course and determine the position of the jump, and then the advance fleet will set off again and wait for the arrival of the fleet at the next point.

And the subsequent voyage will repeat this process until the long-distance voyage is over.

Qi Yiming asked the navigation supervisor, and it will take more than two months for the follow-up escape fleet to catch up.

More than 300 light years, even the Xuefeng super flagship only takes more than a month to go back and forth, so Qi Yiming finally decided to make a trip.

But he did not take the Xuefeng with him, but let the Zhan Lan detach from the Xuefeng super flagship, and then add a special frigate that sends an induction signal to the super flagship, so that Qi Yiming would not be isolated at a critical moment.

After handing over the command of the super flagship to He Zhenzhu, who had just transferred the advance fleet from the escort fleet, Qi Yiming immediately commanded the Zhan Lan to fly towards the galaxy of the mysterious signal source with the special frigate.

Half a month later, the Zhan Lan arrived at the edge of the galaxy where the mysterious signal came from.

Qi Yiming did not rush into the galaxy, but conducted a thorough scan outside the galaxy.

At the same time, several combat probes were launched into the galaxy for a more detailed exploration.

After confirming that there was no obvious danger, Qi Yiming let the Spear slowly enter this strange galaxy. As for the special frigate, Qi Yiming left it outside the galaxy so that he could summon the Snow Peak to join the battlefield when the Spear was in danger.

The star in the galaxy is a red giant with an unusually large diameter. The scientific officer told Qi Yiming that this galaxy should have had 5 to 7 planets, but because of the sudden expansion of the star, the planets close to the star in the galaxy should have been swallowed by the star.

The only planet left now should be the planet farthest from the star before it expanded.

This planet is a blessing in disguise. The heat and light provided by the red giant at this time make it have an atmosphere. The originally barren planet has become full of vitality and even breeds life.

But when Qi Yiming quietly landed on the surface of the planet in this small transport boat, he was surprised.

He saw that the people living on the surface were actually groups of humans in the tribal era.

This made Qi Yiming a little confused. How could this group of savages who ate raw meat and drank blood accurately send signals to the Xuefeng 300 light years away?

Qi Yiming had no choice but to let the small transport boat fly around the planet at the risk of being exposed, but strangely, he could not accurately determine the source of the signal.

This was too strange. In space, it was clear that the source of the signal was on this planet, but why could it not accurately determine the location of the signal on this planet.

Just when Qi Yiming was wondering, the source of the signal suddenly disappeared.

Then Qi Yiming found that the human tribe on the surface suddenly became chaotic. They seemed to feel that some danger was approaching, and they tried to hide in caves everywhere.

The War Spear, which stayed in the synchronous orbit of the planet, was also frantically contacting Qi Yiming at this time.

Because they saw a scene they had never seen in their lives.

The asteroid beneath their feet seemed to come alive. On the back of the planet that Qi Yiming could not see, a mountain was rising rapidly, accompanied by violent earthquakes.

The speed of the mountain's rise had completely exceeded everyone's imagination, and the highest point of the mountain had completely exceeded the height of the planet's atmosphere.

It was a bit unreasonable for Qi Yiming not to feel such a big movement.
