The large screen shows Vicadia making a true prophecy, while the screen next to it shows the physical numbers and indicators of the four test subjects.

With Vicadia's use of the true prophecy, the fluctuations in the mental power of the four experimenters began to increase dramatically, and at the same time, the blood flow in the body increased, the speed of the heartbeat increased, the amount of information transmitted by neuronal tissues increased and decreased, and the energy consumption of the brain doubled.

A few seconds later, Vicadia's true prophecy was completed, and the four test subjects' physical values began to fall, slowly returning to their previous state.

The next thing is a variety of inspections, equipment inspections, personnel physical examinations, busy for more than an hour, and finally came to the answer, that is, the test was successful, and the spiritual link equipment was successfully developed.

However, success does not mean that it can be used, after all, the real prophecy used by Vicadia this time did not consume much spiritual power, so the next step is to carry out various tests and limit tests to accurately determine the transmission limit of the spirit link device and the upper limit of the human body's endurance.

After obtaining the limit of the human body's endurance, it is necessary to limit the spiritual link device, and once it is found that the human body's endurance reaches the limit, the link will be automatically disconnected to ensure the safety of life.

However, in any case, if the real yàn is successful this time, then it means that the Earth Federation can return to the universe at any time, and it is still accurately positioned.

Therefore, the pessimistic atmosphere of the entire Earth Federation was swept away, and everyone was regained and full of war spirit at the same time.

The Pabo Dilong civilization is a 24-hour non-stop cultivation of biological weapons legions, waiting to take revenge after returning to the universe.

In the blink of an eye, thirty years have passed, and the Psychic Link device has undergone its last large-scale experiment. Mass production has already begun.

After the production of the spirit link device is completed, the Earth Federation can open the space channel. The scope is a large universe, but now Xiang Qian and the others have begun to argue about when to return to the big universe.

"I persisted for fifty years and then returned to the big universe. After all, it only takes ten years to connect a space channel, and we have twenty years left, which is enough to connect twice, and there is no danger. The remaining fifty years are just the right time for us to build up. Di Long said sternly.

"I think it's reasonable to go back after forty years, and it's a little safer to leave three opportunities to open the space passage. And back to the big universe, we have a lot of time to build up. At the same time, I think that this time back to the big universe, we should not directly enter the area controlled by the enemy in the end. Instead, return to the periphery of the Andromeda galaxy and rebuild power. Queen Mingyue said.

"Wait a minute, I want to ask a question. Now we can go back to the big universe, and we can go back to the big universe, spend 8,000 years in the outer reaches of the Andromeda Galaxy, and then disconnect the space channel.

After that, we linked to the great universe at one time, and the time point we chose was 8,000 years ago, so that we could have another 8,000 years to increase our strength. If you can do this repeatedly. It doesn't mean we have an infinite amount of time to spare. Green Gesen said suddenly.

After hearing what Green Geson said, several people present were all stunned.

Although this may sound a bit fanciful, it is not logically impossible. But everyone knows that there is nothing wrong with this logic, but no one thinks that this thing will work.

The theory of space-time is only beginning to be studied. Many of these problems are not just speculations, but Xiang Qian and they don't think that there will be such bugs in the rules of the universe. As for why it didn't work, they really couldn't say why.

"I've thought about this question too. But I don't think this will work, as for why I don't know. It can only be said that it is a feeling, after all, such a situation is too unreasonable. But I can let the scientists look into it. For now, let's continue to discuss when to open the space passage. Xiang Qian said.

Then there was another discussion, although it was not determined, but at least thirty years later, the space passage will be opened, leaving thirty years of preparation time, this has been determined.

After the meeting, Xiang Qian found Vicadia and told him about the problem.

As a result, Vicadia was stunned for a moment, looked at Xiang Qian very strangely, and then said: "That idea is definitely not good, in fact, this guess has been found, but because there is no argument, it has not been announced, but everyone has already recognized it."

For example, if we open the space channel and return to the time point of the universe ten years after the outbreak of space turbulence, there is no problem at all. However, it is impossible to go back to ten years before the outbreak of the space turbulence, because at that time, the great universe had the existence of our Earth Federation.

If we go back to the first ten years of the space turbulence eruption, on that timeline, there is already an Earth Federation, and if we appear again, then the whole space-time will become chaotic.

Therefore, when we return to the big universe, we can choose the time point at any time point after the spatial turbulence erupts, because at that time, there was no earth federation in the big universe, but we couldn't choose the previous time point. ”

After listening to Vicadia's words, Xiang Qian figured out where the feeling of something was wrong before, it turned out to be a problem of the paradox of time and space.

"Then if we open the space channel to connect to the universe, and the space channel is disconnected again, then do we still have 100 years?" Xiang Qian asked another question.

"It's hard to say, but it shouldn't be anymore. Now that thirty years have passed in the time of our small universe, and now that we open the space channel, then the normal time of the large universe should be more than 3,000 years after the outbreak of space turbulence.

When the space channel is connected to the large universe, the time of the large universe should be more than 4,000 years later, but the time point we choose is 1 year after the spatial turbulence erupts, which is equivalent to distorting the time axis.

After distorting the time axis, if the space channel is disconnected, then the time axis of the universe will return to normal, that is, no matter when we connect to the universe, our remaining time will not increase or decrease, and will still remain at this ratio of 1:100. Vicadia said.

"Well, I see, when the crisis in the Andromeda Galaxy is resolved, it's time to study the problem of time and space." After Xiang Qian finished speaking, he ignored Vicadia and let the starry sky take out the latest space-time theory of the Academy of Sciences and start looking.

The next day, Xiang Qian told everyone about Vicadia's theory of time and space and the latest space-time theory of the Academy of Sciences, and after several rounds of discussions, the final time for returning to the universe was 40 years later, and the location connecting the universe was outside the Andromeda Galaxy, and the time point was one year after the outbreak of space turbulence.
