Half a month later, the Big Mouth ship was repaired and passed strict sea trials, and there was jubilation on the Snow Lake.

He Jun behaved calmly, not because he was pretending, but because he really didn't think that there was anything to be happy about repairing a big-mouthed ship.

Even if it is a new ship that has just left the factory, it may break down during the voyage, let alone a DIY assembled version? He really didn't have confidence in this big-mouthed ship, otherwise, he wouldn't insist on replacing the reactor for the Snow Lake.

What he hit was that if the big-mouth ship failed, he could still rely on the Snow Lake to continue flying, even if it was a little slower, he could always return to the solar system.

However, just in case, he still ordered to prepare some spare parts.

He Jun then closed part of the cabins of the Snow Lake and began to disassemble the battleship.

In order to reduce damage, the design of the space battleship is somewhat similar to that of the submarine, and the ship is full of airtight cabins and airtight doors, so the Snow Lake does not need to be completely disassembled, as long as all the irrelevant compartments are closed, the hull of the battleship can be removed.

The power compartment is one of the core compartments of the battleship, located in the center of the battleship, and it is not easy to disassemble. Moreover, during the dismantling process, the adjacent reactors are still operating normally, which further aggravates the difficulty of the project.

It took more than a week for the entire ship to replace a reactor.

Replacing the reactor is just the beginning, and the next step is to carry out a series of tests to ensure that the reactor is running smoothly before replacing the other reactors.

It was not until more than 20 days later that the Snow Lake was successfully replaced with three second-generation reactors.

However, at this time, it is still impossible to set off, and the fuel tanks of the Big Mouth and the Snow Lake need to be filled!

This is not a difficult matter, there is a wreck of a large-mouth ship near Xiaoxingde, and if you flip through it, you can find a lot of fuel tanks, many of which have been damaged. But the fuel inside has long been frozen, just melt the frozen fuel and replenish it into the fuel tanks of the two ships.

It took two days to fill all the fuel tanks, and the Snow Lake finally said goodbye to the twin stars and embarked on its journey back.

By the time of departure, most of the ship's crew had already entered the freezer. Only the bridge was left manned.

After a year of rotation, the speed of Snow Lake finally stabilized at one-half light-year per second, and then Snow Lake must continue to fly at this speed for more than 200 years.

He Jun was a little nervous, praying for a safe journey, and finally got into the freezer.

Interstellar space is not nothing, and whether or not it can fly back to the solar system depends not only on the accurate calculation when setting sail. It also depends on the luck of the flight, and no one knows whether they will not wake up.

When He Jun lost consciousness, he was still thinking about whether he would have a chance to wake up again, but in the blink of an eye, his consciousness returned to his mind.

The coldness of the mixed body reminded He Jun that he had just recovered from freezing.

Once raw and twice cooked, he moved his hands and feet a little to leave the freezer cabin and step on the cold floor into the bridge. And check the time at the first time.

The ship's computer faithfully recorded the time elapsed along the way, exactly two hundred and forty-eight years after flying to the double star.

A wave of heat suddenly gushed out of He Jun's cold body. As long as the data at the time of departure is correct, Snow Lake will definitely be back at the gate of the solar system now!

The excited Captain He forgot about the cold and activated the observation equipment as fast as he could, he couldn't wait to see the sun that he hadn't seen for a long time.

However, after seeing the situation outside the ship, He Jun was stunned for a moment.

There is only a void outside the Snow Lake, and there is no shadow of the solar system at all!

The joy in my heart is gone. Instead, there is tangle and panic.

He kept recalling the scene when he set sail, two centuries ago, and still vivid it in his mind, recalling it several times in a row, and recalculating the flight data several times. I called up the automatically recorded flight data again, but I couldn't find the problem.

What the hell went wrong?

He Jun scratched his messy hair in annoyance, and suddenly a flash of inspiration flashed in his mind.

No, the data at the time of departure was extremely carefully calculated and could not be wrong, so the only explanation is that the Snow Lake was yawed!

After all, the binary star is 130 light-years away from the solar system, and as long as you use the simplest trigonometric calculation, you can know that as long as the angle deviation at the time of departure is one degree, when it reaches the target, it will deviate from the target by as much as two light-years!

Although the angle of the Snow Lake was precisely adjusted, even if it was only 0.1 degrees, it was one-fifth of a light-year. Moreover, it is not surprising that the Snow Lake will inevitably pass by other stars on the way as it flies a distance of more than 100 light years, and that its course will be shifted by the gravitational influence of these stars.

That is to say, the overall course of the Snow Lake should not have gone wrong, but for some reason, it deviated from its destination!

Thinking of this, He Jun finally calmed down, since he had already flown one hundred and thirty light years, even if he deviated from the target, he would not be too far away from the solar system, and what he had to do now was to find out the position of the sun and correct the course error.

He Jun couldn't solve this matter alone, and he didn't hesitate to unfreeze a few of his companions.

One person is short and the other is wise, and everyone gets together to discuss and discuss, maybe they can find out the reason, and even determine the current location of the Snow Lake.

Several people quickly reunited in the bridge, although they were separated for more than 200 years, but it felt like it was only a moment, so there was no bloody plot of reunion after a long absence, and after listening to He Jun's explanation, everyone couldn't help but look at each other on the ground.

Lin Kai, who had the fastest mouth, immediately made a newsreel: "I learned how to use naval guns, but I never learned how to look at the stars." Awkward, will you? ”

Awkward and dazed shaking his head: "I will only drive a battleship......"

"Come on, isn't this a discussion with everyone? It's best to come up with an idea, and if you don't have an idea, you can talk about anything else. He Jun said.

"Why the hell does it have to be twists and turns? Wouldn't it be nice to fly straight back? Lin Kai said angrily.

"I want to too, isn't this impossible to fly back?" He Jun said helplessly.

"Captain, listen to you, one of the closest stars to us must be the sun, right?" Feng Fu asked suddenly.

He Jun nodded: "It should be, even if we deviate, we shouldn't be too far away, I have already checked the star map, the starry sky I see here is exactly the same as what I see on the earth, if this is put on hold, I don't need to call you up." ”

The starry sky he is most familiar with is naturally the modern starry sky, as long as he flies for three or five days, He Jun can calculate the detailed distance of these nearby stars through the displacement of battleships and stars, and then compare the memories in his mind to determine the approximate direction of the solar system.
