The affairs of the underworld are strictly kept secret by the Alliance, and this matter is very important, not only related to the two parallel time and space, but also related to some secrets of the five-dimensional time and space.

The scientists of the alliance are studying this cosmic fragment with all their might, and many are even taking advantage of the high flow time of the small universe to speed themselves up.

Dimensional Labs has established a sub-institute in the Netherworld.

……

The long years slipped away unconsciously.

It should have been nearly three thousand years since the Alliance discovered the Netherworld.

The time came to the year 3867 of the galaxy.

Due to the difficulty of preventing the underworld from being assimilated by this universe, the wraiths chose to undergo dimensional reduction transformation in the galaxy 2470, turning themselves into three-dimensional people, and then ascending to extradimensional people.

And the speed at which the Netherworld is being assimilated by this universe is accelerating, probably because the Netherworld is getting smaller and smaller, and its resistance to this universe is getting smaller and smaller.

In the past 3,000 years, humanity has only expanded its territory to 1 billion light-years before it stops expanding.

The main reason for stopping the expansion is that it is not necessary, because the overall technology of mankind has been stagnant since the 1750 year of the galaxy.

Even the Void Zerg has also stopped expanding, maintaining its own domination area of about 300 million light years, and the Void Zerg has also stagnated in technological development.

……

Somewhere in the universe.

"Welcome, human civilization and Zerg civilization have become fourth-level civilizations, and I greet you on behalf of the Shankeqi civilization." A humanoid intelligent creature said very vicissitudes.

"Hello, I'm Beishan of the Primordial Star Civilization." is also a humanoid intelligent creature, the person of this proto-star civilization is very similar to the amethyst people in the alliance, and the body is translucent crystal-like.

And finally, a "ball": "Hello. ”

Kitayama introduced: "The brain of this heavy yuan civilization - weights and measures. ”

"Hello fellow pioneers, I am Huang Haojie, the head of human civilization, and I am very happy to meet you." Huang Haojie responded with a smile.

"Hello, I'm the Lord of the Zerg." Wormman Barr said without being salty.

The main reason why they gathered together was that a large-scale war broke out between human civilization and Zerg civilization in Galactic 2673, destroying a constellation of tens of millions of light-years.

And the protostar civilization, which is close to the human civilization and the Zerg civilization, has to come out to prevent the two sides from continuing to fight.

And the space jumping spaceship that the Dark Matter Pirates inadvertently encountered before was the Primordial Star Civilization, and a war broke out between them and another fourth-level civilization, and many spaceship warships on both sides were thrown to all corners of the universe.

"We are all fourth-level civilizations, and we are at the apex of this universe, so if there is anything, it is better to sit down and say it well, war will only bring destruction." Weights and Measures said coldly.

Apparently he was warning Huang Haojie and Barr.

"Both, Weights and Measures are not wrong, war will only accelerate the death of the universe, once the universe returns to its original point, we will all be unable to escape death, so for the continuation of the universe, I hope you can sign the "Universe Covenant". Beishan handed the two holographic files to Huang Haojie and Barr.

Huang Haojie looked at it, the Universe Pact was a joint convention initiated by the Protostar Civilization, the Chongyuan Civilization, and the Shanchik Civilization, mainly to prevent wars between the fourth-level civilizations from accelerating the destruction of the universe.

In addition, the regions of each civilization are divided, for example, the direct control area shall not exceed the span of 1.27 billion light years, and the satellite control area shall not exceed the span of 6.36 billion light years.

The other regions are all public areas of the universe, and the fourth-level civilizations are not allowed to interfere with and destroy these areas at will.

Huang Haojie knows that there are pros and cons to this convention, but now that human beings have entered an era of high energy and high utilization, there is really no need to control the entire universe, and the other four fourth-level civilizations are not vegetarians.

"I agree."

"Then welcome human civilization to join the Universal Pact." Kitayama said with a smile.

And the wisdom of Weights and Measures and Sanchik are staring at Baal of the Zerg, and if the Zerg refuses, they may have to unite to besiege the Zerg.

After all, the development path of human civilization is relatively peaceful, while the Zerg is full of plunder and killing, and the other three fourth-level civilizations are clear about this.

Barr looked at Huang Haojie, and then looked around at the three of Beishan, although he was unwilling, but in the face of a powerful human civilization, the Zerg was already stretched, if he offended the three old fourth-level civilizations, even if he was immortal, he would have to shed his skin.

"My zerg agrees."

"That's good, I hope everyone abides by the cosmic convention, after all, this universe now has only about 350 billion years of life, if we fight, it will inevitably accelerate the death of the universe, I don't think you all want to die soon, right?" Weights and measures are still very cold.

In fact, the five people present didn't want to fight anymore in their hearts, because they all knew that there was a limit to life in the universe.

Each fourth-level civilization is like a cancer cell living in the universe, once the fourth-level civilization expands or fights in the entire universe, the consequence is that the balance of the universe is broken, and then it quickly perishes.

In fact, this principle is the same as the cancer cells in the human body, the disorderly growth without control will inevitably end up together.

The rules of the universe are like this, from the human body, to the planets, galaxies, and finally to the universe, once the balance is broken, it will inevitably bring devastating consequences.

Just like the savage expansion of the Void Zerg, if the Zerg completely controls the entire universe, then this universe is not far from extinction.

……

Huang Haojie's participation in the Space Summit was in the year 2956, after which mankind almost stopped expanding and began to bury itself in scientific and technological development.

But at this point, a lot of technology is really inadvancing.

Space technology has been extended, such as space jumping, space cutting, space storage, and space folding.

However, these technologies have not allowed human civilization to enter the five-dimensional space-time.

Ancient Star Field.

Dimension Sub-Institute.

Huang Haojie, Song Guangzhi and others are in the underworld world.

At this time, there are only 32 star systems left in the netherworld, and the radius is less than 130 light-years.

In the underworld, the whole person feels very depressed, as if death is watching him all the time.

"Is there a way to stop the shrinking of this cosmic debris?" Huang Haojie felt the dying desolation of the underworld world.

"Unless ......," Song Guangzhi said in a slurred.

"Unless what?"

"I'm not sure, it's a very dangerous plan." Song Guangzhi replied hesitantly.

"Say."

"Transform the Netherworld into a spaceship."

Huang Haojie frowned: "This plan can curb the assimilation of the underworld by this universe?"

"I can't."

Are you kidding me? Huang Haojie looked at Song Guangzhi speechlessly.

"Führer, listen to me." Song Guangzhi thought for a moment and continued: "After transforming the Netherworld, it can't curb the assimilation of this world, but if you keep the Netherworld away from this world, then maybe you won't be assimilated. ”

"Stay away?" Huang Haojie's mind suddenly turned sharply: "What about the consequences?"

"Consequences...... The consequences ......" Song Guangzhi swallowed and vomited.

The others were also very helpless, and they all knew that once the Netherworld and the current universe were separated, the connection between the two sides was very likely to be broken, and the human race might lose the Netherworld as a cosmic fragment forever.

The importance of this cosmic fragment is the key to human beings entering the five-dimensional space-time, and it seems that the gains outweigh the losses.
