The answer is in the hands of the Lixing people, but He Jun is very clear about the situation of the fleet, except for him, the current fleet is afraid that it will never find a second sober person. Then again, even if there is a sober alien, it's strange that he is willing to tell him the answer.

Unwillingly, He Jun tried to call the magnetic wave, but received no reply.

The result was not surprising, but He Jun was still very disappointed.

He sat alone for a long time, trying to find the solar system with the optical system, but the optical system on the battleship was not an astronomical telescope; Second, he is not an astronomer, his understanding of the stars is limited, if it is a modern starry sky, maybe he can still think of a way, but the starry sky of the star era is really powerless, and in the end he failed to find a star that looks like the sun.

Frustrated, He Jun pinned his hopes on his magical intuition again, but this time, even the invincible intuition did not work.

He Jun tossed and turned for two days without sleep, trying all the methods he could think of, not to mention, he really came up with a way to return to the solar system.

The plasma engine on the Big Mouth has long ceased to work, and the Departure Fleet is currently flying by inertia, that is, the fleet has been flying in a straight line, and as long as it leaves the fleet and keeps flying in the direction it came, it can return to the solar system.

Theoretically, this method can indeed work, but the problem is, He Jun can't guarantee that he can drive the spacecraft to the right route, as long as the angle when setting sail is a little bit higher, the final result of the Snow Lake is completely lost in the boundless universe.

Although He Jun also knew that a certain star directly in front of the Snow Lake was the sun, it was only a small area directly ahead. You can find seven or eight stars, and they all look like the sun. There was no way to determine the distance between the battleship and the star, which made him stare dryly, but he didn't dare to leave the fleet.

If the fleet has used the gravitational pull of a star to accelerate in the middle of the fleet. It is even more unknown whether there is a sun directly in front of the battleship...... Humans often use the gravitational pull of celestial bodies to accelerate, and if the Alien Fleet hadn't done this, how could the fleet have reached half the speed of light?

At this point, He Jun still refused to give up, and still tried his best to find a way to return home, but he accidentally found that there was not much tritium in the fusion fuel stored in the battleship, but a large amount of helium 3. When he landed, the sky turned around, and he almost didn't have a stroke on the spot.

The power source of the Soyuz-class warships is a group of fusion reactors, most of which use a first-generation deuterium-tritium fusion reactor, and a few second-generation fusion reactors that react with deuterium and helium-3. The Snow Lake is equipped with two Generation 1 fusion reactors and one small Generation 2 fusion reactor, so every time it sails, it has to carry a large amount of tritium.

Helium-3 is the decay product of tritium, there is as much helium-3 as there is tritium decay, and the half-life of tritium is 12.5 years.

He Jun based on the tritium content of the fuel at the time of departure. With a simple formula, it is easy to calculate the tritium content in the fuel, and it will take more than two hundred and thirty years to reduce it to the current level, that is. The Snow Lake has been flying peas in the void for more than two hundred and thirty years.

This result made He Jun's eyes darken, and he almost went into shock on the spot.

He refused to believe the number and recalculated it again and again. The end result is always unchanged, unless the half-life of tritium is not twelve and a half years. Otherwise there is nothing wrong with this number!

Feelings can be deceived, but the laws of nature do not change by time and place. He Jun had to bite the bullet and believe this damn answer.

Combined with the fleet's flight speed, He Jun calculated that the star fleet had flown more than 120 light-years away from the solar system.

Anyone with common sense knows how far away this is, He Jun couldn't help but be afraid for a while, if he really only flew for nine months when the fleet was gone, and after leaving the fleet, he would run back according to the flight time of nine months, and the possibility of finding the solar system would be infinitely close to zero.

At the same time, he hated the despicability of the star-leavers, and he wanted to drive the battleship to kill all the star-leaving warships now.

However, the impulse could not send the Snow Lake back to the solar system, and if he wanted to go back, he had to rely on the Star Fleet to guide the way, so he could only suppress his anger and hatred in his heart and swallow this evil breath temporarily.

But He Jun swore in his heart that sooner or later he would make the **** star fleet pay for it. Not only the Star Fleet, but the bastards who ordered the orders from the top of the alliance must have known.

"Don't let me know who you are!" He Jun sat in the freezer and gritted his teeth and cursed hatefully, and then lay down in the freezer for the second time.

Feeling the cold skin again, He Jun couldn't help but shudder, and when he returned to his normal consciousness, he immediately judged his situation.

With the experience of waking up for the first time, He Jun quickly opened the freezer cabin, and found that all the freezer cabins had been opened, and everyone climbed out of the freezer cabin naked one by one.

He Jun didn't bother to pay attention to his awakened companions, and rushed to the bridge as quickly as he could get dressed.

Hearing the sound of the door opening, Qiqi immediately turned around, and when she saw He Jun's figure, she immediately showed a sweet smile.

There was only Qiqi alone in the bridge, He Jun reluctantly smiled in response, and Qiqi, who was originally very happy, immediately pursed her mouth aggrievedly.

He Jun didn't have the heart to pay attention to the little girl's mind at all, so he hurriedly checked the fuel situation, calculated the tritium content as quickly as possible, and came up with a result of two hundred and forty-eight years.

"One hundred and twenty-four light years?" He Jun frowned and said.

"What light years?" Kiki asked in surprise.

He Jun immediately told his discovery indignantly, and before Qiqi could finish listening, her face turned iron blue.

She finally knew that He Jun's bad attitude was not aimed at her, but she discovered a shocking secret.

"If I had known where we were now, I would have fucking driven the ship back." He Jun said angrily.

"One-half of the speed of light ......" Qiqi, who calmed down, quickly adjusted the direction of the main screen, and a pair of shining stars appeared in the middle of the screen, "Brother He, the fleet is only more than a hundred astronomical units away from this star, I guess, this is the destination of the aliens." ”

"It must be, otherwise the Aliens would have called us all up." He Jun nodded, "Our cryopod must have made the aliens move, otherwise, how could I have slept for more than two hundred years before waking up?" ”

Kiki said suspiciously: "What are the Aliens doing with so much effort to get us here?" Did they really come to this place to stop the ghosts? ”

He Jun looked at the pair of twin stars surrounding each other on the screen and whispered, "I hope." (To be continued.) )

PS: Well, everyone's surprised?
