With the four-dimensional space crystal, the photosynthetic civilization officially began to build a star gate in the spiral arm of Sagittarius.

There are a total of six star gates built in the plan, connecting α960 Sagittarius and α256 Sagittarius, the base of the galaxy fleet of photosynthetic civilization, and penetrate both ends of the defensive area to achieve the purpose of quickly supporting every corner of the defensive area.

After the construction of these six star gates is completed, a complete defensive loop will be formed, connecting α960 Sagittarius and the defensive area of ??the photosynthetic civilization to form a joint defensive area.

According to the results of the negotiation between the two parties, humans can send scientific research teams and engineering teams to participate in the construction of the star gate.

However, if expected, the human engineering team and scientific research team can provide very little help, and can basically only be responsible for some of the most basic construction work.

This is also the first time that human beings have been exposed to dimensional technology. No matter what they can learn from it, it is a huge gain.

Dimension Technology is now a cutting-edge technology that the Carbon-based Alliance and Palestine Civilization are also studying.

Even in a higher civilization such as the Palestine civilization, the dimensional technology mastered still has not reached its peak, and there is still room for further research.

And Dimension Technology, for humans, is still a hard-to-reach area.

Yang Yuping drew a large part of his computing power and repeatedly read and studied the materials provided by the photosynthetic civilization on the construction technology of the star gate.

Since Dimensional Technology is a field of science and technology that no advanced civilization has fully mastered, it is impossible for this part of advanced civilization to be shared.

Therefore, Yang Yuping can only get a glimpse of the mystery of Dimensional Technology through the technical data of the star gate construction that can be seen.

...

It took six months to build the star gates, and the construction of the six star gates was finally completed.

During these six months, the Palestine Galactic Far-Star Empire continued to carry out the tactics of star map advancement step by step, continuously compressing the space of activities of the three major civilizations of the Carbon-based Alliance.

With the advancement of the star map tactics, the Palestine Galactic Far Star Empire has expanded to the Alpha Sagittarius star domain, further squeezing the space of the carbon-based alliance.

After the construction of the star gate was completed, after a simple test, it was put into use in a hurry.

Fang Yuan indicated that the photosynthetic civilization can be developed, daily resource star mining and resource transportation work.

On the 27th day after the Star Gate was built.

A mining ship of the photosynthetic civilization was attacked by the Palese battleship outside the defensive zone.

The Shenzhou, which was on duty, immediately crossed the star gate and quickly reached the conflicting star field.

The Palerce battleship that attacked the photosynthetic civilization mining ship was immediately evacuated after receiving the approach of the Shenzhou.

Shenzhou launched the "Photon Jump" and chased it up. After three days of chasing, it sank the Palaise battleship and completed the first perfect counterattack.

This is also the first time that the Palese Galactic Far Star Empire has suffered a loss in an encounter after using the star map propulsion tactics.

...

This battle immediately spread throughout the Palestine Galactic Far Star Empire and the three civilizations in the Carbon-based Alliance.

It has been more than a year since the Palestine Galactic Distant Star Empire used planetary map advancement tactics. During this period, no matter what resistance the Carbon-based Alliance did, it had no effect.

Neither the mechanical empire nor the three-eyed civilization could find any way to counter the star map advancement tactics. They could only be passively beaten, and the defensive area was slightly compressed.

And this time, and the only time so far, a Palese battleship that won an encounter victory from the Palese Galactic Far Star Empire and sunk it.

However, this small victory does not belong to the carbon-based alliance.

Because it was the Shenzhou ship.

And humans are not members of the carbon-based alliance.

...

Shield seat spiral arm, inside the Kaztec fleet base.

Kaztick learned that a destroyer had been sunk and looked very dissatisfied: "Our defense zone has clearly advanced to the outer star field of Sagittarius. Why is there still a battleship sunk? Who will tell me?"

For a while, the entire base fell into dead silence.

After a while, the chief of the staff team reminded: "It was the flagship of the human fleet Shenzhou that sunk our warship."

"There is information in the information, and you don't need to explain it!" Kaz'tik suppressed his anger in his tone.

But in his heart he was roaring: It's that elementary civilization again!

He no longer remembers that he heard the words "human civilization" for the first time since he came to the galaxy.

All the information and materials clearly state that this human civilization is just a planetary civilization.

A weak planetary civilization.

However, it is such a civilization that constantly does things that make him angry.

half year ago.

That **** human fleet robbed a four-dimensional crystal of inestimable value from his defense zone.

To this end, he personally used quantum communication to confess his mistake to his teacher Zandar Ikoc, and after much effort, he allowed the mother star to transport the second crystal.

The delivery of the crystal went smoothly this time, and he sent the strongest fleet to escort, and there was no possibility of any problems.

The construction of the inter-galactic star gate has begun, and two-thirds of the construction has been completed. It will take up to two months to complete the construction of this inter-galactic star gate.

When the construction of this star gate is completed, you can go directly from the Scutum spiral arm to the Palestine home planet through the star gate.

The entire voyage only takes one and a half months.

Without this star gate, it would take at least half a year for the Palestine civilization’s support fleet to reach the Milky Way from Palestine’s home planet.

After this star gate is repaired, it will allow the Palese Galactic Far Star Empire to receive more resources and military reinforcements.

Coupled with the star map advancement tactics, this galactic war, the carbon-based alliance will not have any chance.

...

The Galaxy Management Council of the three civilizations of the Carbon-Based Alliance is discussing the next strategic plan almost every day.

The three parties are in dispute.

Judging from the current situation, the situation is becoming increasingly unfavorable for the carbon-based alliance.

If there is no way to break this situation, the Carbon-based Alliance will sooner or later be crushed to death by the Palese Galactic Far Star Empire.

However, if there is a way to break the game, the mechanical empire and the three-eyed civilization would have been used long ago, and there is no need to wait until now.

On the contrary, Piggs, in such a meeting, has a lot of confidence: "If you want to consolidate the defensive power of the defensive area, the most important thing is to build a star gate.

"Only the star gate is the key to defending the Sagittarius spiral arm.

"You don't need to say more, you must know.

"The only encounter we have won right now was when we fought it and sank a Palese battleship."

Although the Shenzhou was attacked, this did not prevent Piggs from showing off.

After all, the star gate was built by the photosynthetic civilization, and humans and the photosynthetic civilization are jointly defending the α200-300 Sagittarius star field.

Therefore, the photosynthetic civilization is also credited for this small victory.

Piggs began to propose: "So, I think you should also build a star gate to connect the Sagittarius defense area to form a complete defense loop."
