Three Sovereigns and Five Emperors

Tianxiang Prefecture Governor's Office.

Gu Jinlai, all forms have returned to their rightful place.

Compared to the solemn discussions held in the Xuanhuang Hall, the atmosphere in the prefectural governor's mansion was undoubtedly much more relaxed.

"Scholar Gu's understanding of nuclear reactors is exceptional. I would like to invite Scholar Gu to join my laboratory so that we can study fourth-generation nuclear reactors together."

Tianxiang Xingjun invited, "We set the standard for users of this generation of reactors at the level of Golden Immortal. Even if the first test subject is a third-level Golden Immortal, it doesn't matter. We will build it first and then optimize it step by step. If we can optimize it to the point that even a level nine pilot can use it one day, that will be an unprecedented success."

"A fourth-generation reactor? A reactor with the Devouring Dao as its core?"

This Gu Jinlai.

Previously Gu Jinlai thought that the gap between fourth-generation reactors and third-generation reactors was too large.

Only now did he realize that, from beginning to end, the goal of the Xuanhuang Immortal Dynasty should have been the fourth-generation reactor.

Black hole reactor.

Gu Jinlai have considered their own Great Sun Core.

The Great Sun Eternal Law, even now, remains a gold-level skill and has not yet broken through to orange, which corresponds to the realms of Great Dao Golden Immortal, Immortal Golden Immortal, and Dao Ancestor.

What will be the next form of the Great Sun Core, which is derived from the Great Sun Eternal Law?

White dwarfs, neutron stars, black holes!

White dwarfs and neutron stars are both the result of stellar evolution at its end. When a star completes its long life, low-mass and medium-mass stars will become white dwarfs.

Massive and supermassive stars will cause a supernova explosion. How the star evolves after the supernova explosion will depend on the mass of the remaining stellar core. When the mass of the remaining stellar core reaches 1.4 times that of the Sun, its gravity will be strong enough to compress the atoms in the stellar core to the point that electrons and protons combine to form neutrons. At this point, the stellar core becomes a neutron star.

Further up, it becomes a black hole.

White dwarfs, neutron stars, black holes!

It depends on the mass the star had before it collapsed.

Gu Jinlai, people have focused their attention on the characteristics of supernova explosions.

Next, their attention turned to the core of the Great Sun, which was formed by the Great Sun Eternal Law.

"If I'm willing to take a gamble, perhaps I can utilize the characteristics of a supernova explosion to complete the transformation and allow the core of the Great Sun to undergo a metamorphosis..."

The Way of the Heart, Through the Gu Jinlai.

After a moment, he suppressed the thought.

Firstly, he did not believe that the mass of his Great Sun Core was large enough to transform into a black hole.

He estimated the gravitational and nuclear forces he possessed, and then checked the structure of the Great Sun's core. He concluded that if he allowed the Great Sun's core to enter a supernova explosion state, the possibility of it transforming into a neutron star was greater than the possibility of it turning into a black hole.

Secondly...

He wasn't confident that he could handle the impact of a supernova explosion.

He had a premonition that when the Great Sun Core within his body could truly transform into a black hole, the combat power he could unleash would reach its peak even among Great Dao Golden Immortals.

It's important to understand that although his mental strength has reached the fifth level of Golden Immortal, it doesn't mean he has the corresponding power.

If he were to leave the Xuanhuang Immortal Dynasty and go to the outside world, he could at most rely on his mental advantage to exert the combat power of an ordinary Golden Immortal.

Even if the Xuan Yuan Ancestor of the Xuanxian Realm were to be resurrected, he might not be able to match him.

"Using the Devouring Dao as the core of the reactor is quite accurate; that is indeed our plan."

Tianxiang Xingjun said, "The evil god has not yet evolved the power to degrade and devour the Great Dao. If we can build a reactor with the Great Dao of Devouring as the core, the pilots will even have the power to threaten the evil god."

Gu Jinlai listened with some curiosity, but couldn't help asking, "The Cosmic Heart Defense Line gathers a large number of surrounding civilizations, and there must be quite a few civilizations with advanced technology, right? Why do we still need to conduct research on it?"

"Indeed, some civilizations that do not follow the path of cultivation have mastered powerful technologies. Some civilizations are so technologically advanced that they can even capture immortals for research. However, all technologies are meaningless in the face of power that involves the Great Dao."

Tianxiang Xingjun said, "Let alone Immortal Golden Immortals, even Great Dao Golden Immortals can ignore more than 90% of technological power."

As he spoke, he seemed to have thought of something, "In the Heart of the Universe defense line, such civilizations have always been only auxiliary, cooperating with other powerful civilizations. If the two are combined, they could form a new system."

"The level of the Great Dao..."

Gu Jinlai, this has been associated with the eerie and all-pervasive nature of the Devouring Dao...

This force, which is almost equivalent to the gravitational pull of the universe, is indeed difficult for technology to counter.

Unless, of course, that technological civilization has become so powerful that it can intervene in the operation of the entire universe, or even modify the rules of the universe.

"In fact, our Xuanhuang Immortal Dynasty has changed a lot in the short few thousand years, and these changes are all due to the support of some civilizations in the Heart of the Universe. Even the reactor technology we use now comes from those civilizations. What we have been doing for the past few thousand years is learning these technologies and improving them in the environment of our Xuanhuang Immortal Dynasty where the Great Dao of Devouring has an influence."

The Heavenly Star Lord said.

Those who understood the passage from Gu Jinlai nodded in agreement.

Learning also takes time.

Especially knowledge that is very different from one's way of thinking.

Imagine bringing a biological spaceship capable of traveling at one-tenth the speed of light to Blue Star and having the Blue Star's human civilization study it. Due to the different directions involved, it would take Blue Star's civilization at least a thousand years to develop biotechnology from scratch and actually create such a spaceship.

"A thousand years ago, His Majesty the White Emperor issued a conscription order to our Xuanhuang Immortal Dynasty. Most of these pilots will have to step onto the battlefield at the heart of the universe in the future..."

Tianxiang Xingjun revealed another secret. "In that battlefield, the Great Daos intersect. The further in you go, the greater the interference and the greater the impact. If the pilots don't master enough methods of using their mental power to activate the reactor while resisting the interference of the Great Daos, they probably won't even be qualified to exert their strength."

"The White Emperor!?"

The White Emperor, one of the Three Sovereigns and Five Emperors!?

"A thousand years ago?"

Gu Jinlai, it becomes clear why the Xuanhuang Immortal Dynasty's efforts to forge an immortal grotto-heaven suddenly became so intense a thousand years ago.

"So, the Three Sovereigns and Five Emperors are still fighting a great battle on the defensive line of the Heart of the Universe?"

"Good."

Tianxiang Xingjun nodded. "The powerful beings sealed the evil god in the deepest part of the heart of the universe, faced the Dao Ancestor directly, and sought to resolve the death crisis brought by the Dao Ancestor, hoping to solve the problem once and for all. Currently, the top immortals, including His Majesty, are in charge of the defense line of the heart of the universe to resist the evil god."

"An immortal venerable one..."

Gu Jinlai, people have been asking, "What is the status of the Cosmic Heart Defense Line?"

"The Heart of the Universe Defense Line..."

The Celestial Star Lord gazed upon the Gu Jinlai, pondering, seemingly organizing his thoughts.

After a long pause, he slowly said, "The Heart of the Universe Defense Line is just a general term; in reality, it can be divided into eighteen regions, or war zones."

As he spoke, Tianxiang Xingjun stretched out his hand, and a patch of starlight appeared in his palm, just like the "Milky Way" he had seen before.

At the "center of the galaxy", eighteen regions are clearly visible.

"The Six Realms, the Four Seas, and the Eight Desolations."

Gu Jinlai, people have looked at these stars and naturally come into contact with the information contained within them.

The eighteen forces, or rather the eighteen war zones, are like a Dyson sphere covering a star, covering this heart of the universe and sealing off the evil gods and spirits captured within it.

"Our Xuanhuang Star Region is located in the Xinhuo Star Sea, which is situated in the middle of the Four Seas. This Star Sea is under the jurisdiction of the Three Sovereigns, Five Emperors, Eight Emperors, and various Immortal Venerables."

Tianxiang Xingjun said, "As the direct forces of His Majesty the Three Sovereigns and Five Emperors, our Xuanhuang Immortal Dynasty and Xuanhuang Star Region should do our utmost to train enough qualified pilots and build enough mechs to go to the Xinhuo Star Sea to participate in the war now that His Majesty has summoned us."

Looking at the starry sky projected by the Celestial Star Lord, Gu Jinlai frowned slightly.

Not because of anything else, but because...

It's too spacious.

This starry sky is so vast it's unimaginable.

"Shouldn't other civilizations have existed under the rule of the Three Sovereigns and Five Emperors?"

Gu Jinlai, people have asked, "Why wasn't this marked on the star map?"

"Evil gods, and some beings who fear the Dao Ancestor's purge and have transformed themselves into gods, are constantly hiding in the shadows, trying to strike at starfields. Although they are unlikely to amount to much, since the elites of all realms have been mobilized to the Heart of the Universe, once they start stirring up trouble, the damage they cause will still be considerable. Evil gods are somewhat better; their avatars degrade rapidly, and they have to stop for a long time after destroying one or two worlds. But gods... pose a tremendous threat to the civilizations behind them..."

Tianxiang Xingjun said, "The gods have not yet completed their degradation and are essentially still immortal golden immortals. In other words, they can completely disguise themselves as a cultivation civilization. Under such circumstances, if we rashly mark all the civilizations on the star map, wouldn't we be telling those gods which worlds are easy for them to conquer?"

Gu Jinlai nodded in sudden realization.

This behavior also serves as a form of protection for other civilizations.

"Of course, there's another reason..."

As Tianxiang Xingjun spoke, he said in a tone that was somewhat uncertain, "It is said that in a long time ago, an extremely fierce war broke out in this universe, a war that was even more intense than the war between gods and evil gods. That war destroyed most of the civilizations, so much so that this starry sky now looks much emptier than we expected."

"A great war a long time ago?"

A thought Gu Jinlai him, "How long?"

"A very long time ago, so long that many civilizations have lost their records of it. It is said that in that era, there was a great being called a 'Saint,' whose status was even comparable to that of the Dao Ancestor..."

Tianxiang Xingjun shook his head as he spoke, "However, similar legends are ambiguous. In addition, the threat of the Dao Ancestor is like a sword hanging over the heads of Immortal Golden Immortals. Everyone fears him like a tiger, so it is reasonable to have similar fantasies. Anyway, those life forms that claim to be comparable to the Dao Ancestor have been proven countless times that when the Dao Ancestor really wants to eliminate them, they have no room for resistance. Just listen to it as a story."

As he spoke, he waved his hand. "How about it? Want to work with me on researching fourth-generation nuclear reactors?"

"Certainly."

Gu Jinlai, people have calmed their minds.

He also wants to learn about fourth-generation nuclear reactor technology in preparation for transforming the core of the Great Sun into a black hole in the future.

"I would be delighted."
