Inside the Shenzhou bridge.

"The most prudent evacuation route is to return to the Sagittarius spiral arm from λ253 Scutum. The whole 36-day journey is also the fastest route to evacuate the Palestine Galaxy Far Star Empire defense zone." Lang Xiaonian used his finger to draw on the holographic star map. A line with many turns.

The human fleet began to consider evacuation routes.

Four-dimensional space crystals are things that need to be escorted by two standard fleets in higher civilizations, which shows how high their value is.

Now that the human fleet is in the defense zone of the Palestine Galaxy Far Star Empire, you don't have to think about it, the enemy will send a stronger fleet to chase, and it will be chasing and intercepting.

It is not so easy to take the four-dimensional crystal to leave the shield arm.

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

"This is still uncertain, because there is no accurate intelligence to show what star field the enemy's defense zone has pushed, and it will probably be able to withdraw from the enemy's defense zone in 6 or 7 days." Lang Xiaonian couldn't give an accurate one. Reply.

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

However, there are levels of reconnaissance intensity.

The point is that the information provided by the Carbon-based Alliance is too little.

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

Because, now with the fleet broke into an extremely dangerous star field, I don't know where the enemy is, and I don't know when the enemy will appear.

It was like entering into the fog of war, and the eyes were completely dark, but the enemy could clearly see their actions.

This feeling is very bad, it's like walking a tightrope, and any wrong step will be the end of the world.

After human beings walked out of the earth to the stars, every step was so thrilling.

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

...

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

After confirming the route, Fang Yuan led the scientific research team into the cabin, ready to see the four-dimensional crystal.

After opening the crystal container, I finally saw the contents inside.

It is a polyhedron that reflects rhombohedral light. People standing in front of it will be illuminated with hundreds of faces.

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

The scientific research team was the first to conduct quality inspections and made a surprising discovery: "The quality of this crystal is very large, exceeding one hundred tons."

However, under visual inspection, this crystal is actually only the size of a basketball.

It looks small, but the quality is great.

Under normal circumstances, it can be considered that the density is very high, but under the electron microscope, it is found that the density of this crystal is not very high, and the distance between the particles is similar to that of ordinary substances.

"There is a four-dimensional structure." Ye Zheyu saw the crux of the problem with an ability, and immediately said it.

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

This crystal has a four-dimensional structure, so the part that can be seen with the naked eye is not all, the quality is mainly in the four-dimensional structure.

The part of the polyhedron seen by the naked eye is actually just a face of the four-dimensional crystal in the three-dimensional world, or it is called a projection.

"Get communication with Piggs and let them carry out remote scientific and technological support." Fang Yuan ordered.

Human beings are completely ignorant of this kind of dimensional technology, so they must have the help of photosynthetic civilization.

Moreover, in this process, it may be possible to absorb dimensional technology and create opportunities for mankind's technological leap.

Of course, dimensional technology is a technology that all higher civilizations are studying, and it is an inaccessible level for humans today.

After the communication is connected.

Piggs was very surprised: "General Fang Yuan, where are you? I just received information that a fleet of the Palese Galactic Empire in the Shield was attacked. Did you do it? Theirs? The top executives are in panic."

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

Piggs was stunned when he saw the polyhedral crystal appearing in the picture.

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

After all, this kind of crystal will only be used when building a star gate. Normally, only the parent star will be preserved, and it will not be visible at all.

"Wait a minute, wait a minute... I may need time to convene scientists in this area, and I may also need help from the home planet." Piggs said hastily.

"Then hurry up, and pass all the information about crystals in the 4D space. I know that many of the information about the crystals in the 4D space are confidential, but I need these information now. You should be clear. If I can send this Bringing things back to the Sagittarius will help us a lot," Fang Yuan said.

"Of course, of course... of course I know. I am thinking about whether to contact the Mechanical Empire and the Three Eyes and get some help from them. I am alone, I am worried that I can provide too little help." Si was very excited.

He is very clear about the value of such a four-dimensional crystal.

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

After serious consideration, Fang Yuan agreed: "Yes."

Although there are many internal problems in the carbon-based alliance, the goal is the same in dealing with the Palestine civilization.

Therefore, if the mechanical empire and the three-eyed civilization are willing to provide help at this time, it will naturally be better.

It didn't take long.

Piggs will get all the information about the four-dimensional space crystal from the home planet, some of which are confidential information.

The emptiness of the mother star obtained by Piggs, temporarily decrypted this part of the information, and provided it to humans.

If it is normal, this kind of technology that is still being studied by this civilization will not be possible to share classified information with other civilizations.

Only when the same is a higher civilization and need to share technology with each other will it be used.

On the Shenzhou.

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

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

Although there are a lot of contents that are not understandable, the mystery of Dimensional Technology can be glimpsed from the understandable part, which is like opening the door to a new world and seeing a different multidimensional universe.

Fang Yuan's gaze fell on the source analysis of crystals in the four-dimensional space.

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

This explanation is a bit unexpected.
