Cheng Yuan thought about it for a while, and then refused: "It's still not necessary, what can they do to mobilize everyone to become cannon fodder commandos?"

As soon as Cheng Yuan said this, Zero was also stunned, even if he told them, there would be no change, is it really the same as Cheng Yuan said, set up a cannon fodder commando team to send people to the past?

"Now that the population is already small, it's just a matter of using robots on the battlefield. "Cheng Yuan doesn't want the total number of human beings to decrease any further, it's not that he wants to be a virgin who protects all mankind, but the potential foundation for population to determine the future of mankind.

The relationship between population and development potential is very close, and this has been fully confirmed by the two countries of China and India.

Although India and China cannot be compared, there is already such a momentum.

"Okay. "Large-scale construction began at zero in preparation for the upcoming war.

Cheng Yuan was not idle, after returning to Earth, he said hello to his family, explained a few words to Guo Xiaolian, played with his daughter Yating for a while, and then went into the room alone.

Cosmic warfare is more dangerous than the war on the planet, and if the fighters are concentrated in the planet, as long as it does not lead to the direct destruction of the body, there is still a chance to escape.

And in a space war, if the body is destroyed, whether it is a mecha or a battleship, the only result that awaits the pilot is death!

As for things like escape boats, it is difficult to survive on a battlefield where the fighting is fierce.

Although Cheng Yuan already plans to use robots as war units, the protection he needs must also be there.

Lying in the nursing cabin that had not been used much in the room, Cheng Yuan closed his eyes and immersed himself in the core of his mind.

The golden core is the same as ever, surrounded by mystical symbols, as if guarding their masters.

Approaching the core, Cheng Yuan stretched out his hand, and as his palm approached the golden symbols, those symbols seemed to be under some kind of control, scattering a small part and floating around him, beginning to revolve around him.

"Anti-Transition Devices. Cheng Yuan crossed such a word in his mind.

Soon the golden symbols jumped, and after being entangled and combined in a disorderly manner, they changed into another set of symbols, and they fluttered into the depths of consciousness.

The technical data of an anti-transition device made Cheng Yuan's head slightly swell, and this feeling did not last long, and he recovered after only a moment.

Anti-Jump technology can prevent any foreign warship from jumping into the battlefield through jump technology, and can even appear suddenly from their unknown place to carry out a sneak attack or flank assault.

This device is a highly desirable device for all civilizations in the Cosmic War, but from what he knows, it seems that the Crystal Spirit Civilization does not have such equipment.

Although they possess leaping technology, they are unable to prevent or interfere with enemy jumps.

If he has this kind of technology, then in this war, he will be able to seize the initiative! After all, in terms of the power of weapons alone, there will not be much difference between the weapons of the two sides.

You can take out our flagship or core ship with a single shot, but I can also take out yours.

In this case, he who can freely shuttle through various areas of the battlefield will naturally be able to occupy the initiative in the entire war!

When he wants to attack, he can attack unscrupulously, and when he wants to retreat, he can leave easily!

The need not to go far was not that, and after fully receiving the anti-jump device, he then thought of something else in his mind.

"Wormhole jammer. ”

The distance between the Crystal Spirit Civilization and the solar system is very long, and it is not easy to reach it just by jumping, and even if they could, they would never have spent so much energy to jump from the Centaur system.

If they do, they will have little energy left when they arrive in the solar system. So how will the next battle be fought?

Moving forward by hand-cranking?

Rowing?

Maybe the resistance of the vacuum is very small, and the rowing finger may be really fast......

Therefore, the crystal spirit will definitely use the wormhole, a shortcut that exists in the universe itself, to shuttle and sail to shorten the journey and ensure sufficient energy reserves.

All he had to do was interfere with the wormholes, and the star map he obtained from the Titan Fortress clearly recorded the number of wormholes that existed between the Centaur galaxy and the solar system.

Although the number of records in the star map cannot be said to be absolute, at least the other party has only discovered these.

All he has to do is to drop several probes in these already discovered wormholes, and as long as he finds the opponent's warship, he will use the wormhole jammer to interfere at once.

Wormholes are not a safe place, and as a shortcut to spaceflight, the inside of a wormhole is definitely not a safe place.

Perhaps when you are impulsive and calm inside, you will feel that your wormhole shuttle is very calm. But once you encounter a cosmic storm or space shock or something like that, then you will find that this shortcut can swallow you in an instant!

Therefore, under normal circumstances, after discovering a wormhole and testing the security of the wormhole, any civilized force will establish a stable detection device at both ends of the wormhole to detect the stability of the wormhole and also monitor whether other forces have tampered with the wormhole.

However, now on Cheng Yuan's side, he doesn't often use wormholes, so he doesn't prepare anything in this regard.

As for the crystal spirits, they had already been thrown into a large area of the Centaur galaxy after the great war thousands of years ago, so the monitoring of the wormhole side was long gone.

Even if there was before, it would have been scrapped long ago if it had not been maintained for thousands of years.

With these two things, the odds of winning this battle are also much higher. Now he also needs to strengthen the overall protection of the battleship, and the energy shield he is using now is invincible on Earth.

But the collision between civilizations, it is impossible to say.

Cheng Yuan doesn't like to fight evenly matched, and unilateral crushing is what he pursues.

And he has such capital, and the core of science and technology is his capital to crush others!

Cheng Yuan remembered that he had watched a science fiction movie before, in which an alien civilization actually established an energy barrier in the universe to block the invasion of foreign civilizations!

Anything that touches this barrier will be shattered by the barrier's energy. Unfortunately, in the end, this barrier was breached by hostile forces who broke into the interior.

When he first saw this thing, Cheng Yuan thought about another question, if this kind of barrier could be installed on his own warship, would it be able to create a warship that could shuttle on the battlefield at will?

If this kind of barrier can really appear on the battlefield, it will really be the rhythm of hitting whoever dies!

Cheng Yuan infiltrated his ideas into the core of science and technology, and soon the core had feedback.

Four brand-new runes slowly extended from the core, and then merged into the runes that were originally wrapped around Cheng Yuan, tangled together and fused into one!

When the runes merged into Cheng Yuan's body, Cheng Yuan suddenly felt as if someone had drilled into his brain with an electric drill, and the stinging pain in his heart made his face twitch.

Soon, Cheng Yuan was in a trance and woke up with his eyes.

Cheng Yuan got up and rubbed his head, wiping a handful of sweat oozing from his forehead, "Damn, the technical content of this thing is too advanced, and I don't know if I can make it." ”

......

In the centaur system, the ruins of the battlefield, countless search ships of the crystal spirits have been dispatched here to begin a large-scale search.

A brand new civilization appeared in front of them, and even if Jin had just reported the news, the real ruler of the Central Star couldn't wait to order Jin to start searching and probing the strength of the other civilization.

Maybe the cultural form of each civilization is different, but no matter what civilization, they will always have a consensus, and the most direct and easiest way to obtain benefits is robbery!
