But now there is a very difficult problem, because the number of people who came to the ground this time is large, and the energy required is too heavy, so neither can give up one or the other.

And this time, not only the astronauts who are driving the alien spacecraft and the aliens who are going to return to outer space, but Jiang Cheng also has to place several aerospace professionals in the alien world.

After all, Jiang Cheng did not personally accompany these people, so there are a few aerospace professionals who may ensure the safety of this return to outer space mission.

Now the number of people has been increased, but the problem of carrying weight has been very tricky, if there is too little energy, the crowd may fly halfway without a power system.

Then they will spend the rest of their lives in the universe, and in order to prevent such a thing from happening, the laboratory hurriedly contacted the alien civilization and asked them to find a way to overcome this difficulty.

Ground laboratories are also conducting research on energy compression, and if energy can be compressed to a certain weight, this can also realize the plan to return to outer space.

But when all the scientists heard about the plan, they shook their heads and looked at each other to discuss.

"If you want me to say, this is simply impossible, and now that we have increased our personnel, the energy we bring must be reduced to 1/3 of the current level, which is simply a fantasy."

The person next to him also explained his thoughts.

"yes, wouldn't it be nice if these aliens were allowed to teach their own alien spaceships? It doesn't matter what happens to us if they die, and once their number is reduced, there will be a little more energy, and there is no need to worry about the energy burden. ”

Although everyone was whispering, Jiang Cheng heard it clearly, because he could know what everyone was thinking, and such a thing was an unfinished task in the history of science and technology on Earth.

But Jiang Cheng still had to warn everyone.

"Although no one has completed this task yet, it does not mean that our laboratory cannot complete this task, because this is justified, as long as we do it right, it is completely possible."

However, although the scientists thought that this was possible on the surface, they were lazy and lazy in action, and they did not put their minds on it at all, thinking that this was a bamboo basket for nothing.

But Jiang Cheng didn't believe in this evil, after the help of the alien civilization, plus Jiang Cheng stayed in the laboratory day and night to conduct research, he didn't expect to really compress the energy to 1/3 of the size.

This shocked the scientists, but they didn't expect Jiang Cheng to really do it.

With an attitude of disbelief, the scientists hurriedly tested the compressed energy, but they did not expect that the energy loss was only one ten-thousandth of the original size.

In other words, after the energy bill has been reduced to 1/3 of its original size, there is basically no energy loss, which is not only a great step in the history of science and technology today.

Scientists dare to say that if this was not completed by Jiang Cheng, no scientist would have done this in the next 100 years.

As a result, the problem of energy load on alien spacecraft was solved, and Jiang Cheng hurriedly ordered several professional aerospace experts to accompany the astronauts back to outer space.

The aliens knew what problems they were facing, but they didn't know the plans for the ground labs, watching the astronauts carry energy.

This made the aliens a little incredulous.

"Is that all the energy we need for this flight?"

The aliens were very puzzled, the last time it was far more than these energy sources were not enough, they still returned from the halfway, could these energy sources really take them back to outer space.

The astronaut gave the alien a blank look.

"Your mission is not to question us, just to follow us back to outer space."

When he was about to fly, Jiang Cheng repeatedly told the astronauts to keep in touch with the ground laboratory, and report to the ground laboratory if there was anything.

Jiang Cheng remotely commanded and controlled the alien spacecraft, and the news of the safe landing of the alien spacecraft could be regarded as a safe landing, which made all the members of the laboratory put their hearts down.

Jiang Cheng, who was on the ground, was not idle, and after he remotely commanded the alien spacecraft to return to outer space, he hurriedly held a meeting in the ground laboratory.

"It's not a way for us to go on like this, although the passage between outer space and the earth has been successfully built, and we have developed alien spacecraft, but the energy problem is still worth thinking about."

Everyone has thought about this because they first thought about changing the energy source, but the current energy is the most advanced they know so far, and it is the energy used by all aircraft.

"But Professor, we haven't found any new energy sources that can replace this energy source."

But Jiang Cheng had an idea in his heart, he felt that the laboratory could make some energy by itself, and then mix the energy to see if he could get new energy.

This was just Jiang Cheng's whim, and as a result, under the argument of the truth, this conjecture was overturned without hesitation, so it is basically impossible to make self-made energy.

Now the laboratory must find a new energy source to solve the urgent need now.

"Professor, this energy compression also took a few days, and it was self-defeating that the compression was successful, with our current technology, there is no guarantee that every compression will be successful."

Jiang Cheng nodded and motioned for the person to continue.

The scientist showed that they now have two solutions, the first is to reduce the load on the spacecraft, and the second is to find new energy sources.

So the whole meeting discussed in the end, it is still necessary to find new energy sources for alien spacecraft.

Others proposed to Jiang Cheng. "If you can get the solution of the alien civilization, you can also solve the urgent problem now, after all, they can shuttle between the two civilizations."

It's not that Jiang Cheng hasn't thought about this problem, it's just that this is an internal secret issue that belongs to a civilization, and he is afraid that he will be civilized in appearance, not only not giving them technology, but also giving them a charge of wanting to steal the secrets of civilization.

Only then did everyone realize that this was more risky, so they still felt that continuing to look for new energy sources was the way to go, but this discussion gave him an inspiration.

Jiang Cheng thought that they could do research in this direction, and if they could get the energy on the alien civilization aircraft, they could completely study what these energy sources were.

In this way, you can follow this direction and find a new energy source for the alien spacecraft, and all the problems will be solved.
