Inside the Shenzhou Bridge.

"The most cautious evacuation route is to return to Sagittarius from Shield λ253, which is 36 days in total, and it is also the fastest route to evacuate the defense zone of the Milky Way of the Milky Way. "Lang Xiaonian used his finger to draw a line with multiple twists on the holographic star map.

The human fleet began to consider the evacuation route.

In higher civilizations, four-dimensional space crystals need to be escorted by two standard fleets, which shows how valuable it is.

Now the human fleet is in the defense zone of the Palesey Galaxy Far Star Empire. Needless to think about it, the enemy will send a stronger fleet to pursue it, and it will encircle and intercept it.

It is not that easy to leave the shield spiral arm with the four-dimensional space crystal.

Fang Yuan rubbed his chin and asked, "How long will it take to leave the enemy's defense zone?"

"This is not certain, because there is no accurate information to show what star field the enemy's defense zone has pushed into. It will probably be able to withdraw from the enemy's defense zone in about 6 or 7 days." Lang Xiaonian could not give an accurate answer.

Because in actual combat, all areas that can be controlled by reconnaissance can be regarded as defense areas.

However, there are hierarchical differences in reconnaissance strength.

The key is that the Carbon-based Alliance can provide too little intelligence.

After seizing the four-dimensional space crystal, Fang Yuan began to feel a little anxious.

Because, now he has led his fleet into an extremely dangerous star field, and he does not know where the enemy is or when the enemy will appear.

It was like entering the fog of war, and the eyes were pitch black, but the enemy could clearly see its own actions.

This feeling is very bad, like walking on a tightrope. Any mistake in any mistake will be a result of being broken into pieces and will never be restored.

After humans walk out of the earth and towards the starry sky, every step is so thrilling.

In fact, Fang Yuan didn't want to be so thrilling every time, but for a planetary civilization, there are too few cards available in his hand.

...

The fleet sailed according to the routes drawn by Lang Xiaonian.

After confirming the route, Fang Yuan took the scientific research team into the cabin and prepared to see the four-dimensional space crystal.

After opening the crystal container, I finally saw what was inside.

It is a polyhedral reflecting the diamond-colored light. When a person stands in front of it, he will be illuminated with hundreds of faces.

The strangest thing is that this thing floats in mid-air.

The scientific research team was the first to conduct quality inspection and made an amazing discovery: "The crystal is of great quality, more than one hundred tons."

However, it is estimated that this crystal is actually only as big as a basketball.

It looks small, but it is of great mass.

Generally speaking, it can be considered that the density is very high, but under an electron microscope, it is found that the density of this crystal is not very high, and the distance between particles is similar to that of ordinary matter.

"There is a four-dimensional structure." Ye Zheyu used his superpower to see the key to the problem and immediately said it.

Fang Yuan copied his high-dimensional visual eye and understood it at a glance.

This crystal has a four-dimensional structure, so the part seen with the naked eye is not all, and the mass is mainly in the four-dimensional structure.

The polyhedral part seen by the naked eye is actually just one side of the four-dimensional space crystal in the three-dimensional world, or a projection.

"Get communication with Piggs and let them provide remote technical support." Fang Yuan ordered.

Humans are completely unaware of this dimensional technology, so photosynthetic civilization must be helped.

Moreover, in this process, dimensional technology may be absorbed and create opportunities for human technological leap.

Of course, dimensional technology is a technology that higher civilizations are studying, and it is an untouchable level for today's human beings.

After the communication is connected.

Piggs looked surprised: "General Fang Yuan, where are you? I just received the information that a fleet of the Galactic Far Star Empire in the Shield was attacked. Did you do it? Their senior management was all in panic."

Fang Yuan adjusted the communication screen to the four-dimensional space crystal and said: "I just got it. I need remote technology support. First, determine whether this crystal is a four-dimensional space crystal."

When Piggs saw the polyhedral crystal appearing in the picture, he was stunned for a moment.

In fact, he has only seen four-dimensional space crystals in the information, and has never seen such things with his own eyes.

After all, this kind of crystal is only used when building a star gate. Usually, only the parent star is preserved and cannot be seen at all.

"Wait a minute, wait a minute... I may need time to gather scientists in this field, and may also need help from my parent star." Piggs said quickly.

"Then hurry up and send all the information about the four-dimensional space crystal. I know that a lot of information about the four-dimensional space crystal is confidential, but I need this information now. You should know how helpful it will be to us if I can bring this thing back to Sagittarius." Fang Yuan said.

"Of course, of course... I know. I'm considering whether to contact the Mechanical Empire and the Three-Eyed Clan to get some help from them. I'm alone, and I'm worried that I can provide too little help." Piggs was very excited.

He knew very well how valuable such a four-dimensional space crystal was.

If this four-dimensional space crystal can be really brought back to Sagittarius, it means that the star gate can be built, which is of great significance.

After careful consideration, Fang Yuan agreed and said, "Yes."

Although there are many internal problems in the Carbon-based Alliance, the goals are consistent in dealing with the Palesey civilization.

So, if the Mechanical Empire and the Three-Eyed Civilization are willing to provide help at this time, it will be better.

Not long after.

Piggs sent all the information about the four-dimensional space crystal obtained from his parent star, and some of them were confidential information.

The void of the parent star obtained by Piggs temporarily decrypts this part of the information and provides it to humans.

If it is normal, this kind of technology that is still being studied in this article will not be able to share confidential information with other civilizations.

Only when both higher civilizations need to share technology with each other will they be taken out.

On the Shenzhou.

All the scientific researchers in the fleet are browsing the information they have obtained.

These information about four-dimensional space crystals will inevitably involve dimensional technology.

Although there are many things that cannot be understood, from the understanding part, you can get a glimpse of the mystery of dimensional technology, which is like opening the door to a new world and seeing a different multidimensional universe.

Fang Yuan's eyes fell on the analysis of the source of the four-dimensional space crystal.

The explanation given by the photosynthetic civilization is that the four-dimensional space crystal is a fragment left by the four-dimensional civilization.
