In that spirit-soul battle, Siebbins died, but his consciousness in turn replaced the soul of the undead, because his spiritual strength was stronger than that of the undead.

The best way to understand the enemy is to be a part of it, and Sibbons became an undead, an undead with the soul of a Natt.

It was only then that the undead learned that the undead had the ability to devour souls and plunder each other's memories, so the undead became more and more aware of the Nats.

In order to prevent Shimbins's existence from being discovered by the memory of the undead, this secret was confined to a small number of high-ranking people, all of whom were old and exhausted, because statistics showed that the undead did not include such Nat people, whose lives began to fail.

And Sibbins was also sent to the outside world to try to blend into the circle of undead creatures and gather more information for the Natters.

The war lasted for tens of thousands of years, there were more and more undead creatures, and materials became more and more difficult to obtain, and as the wisdom of the undead became higher and higher, one of the powerful undead conquered the rest of the same kind and became a powerful king.

This powerful undead king organized an army of millions and surrounded the spatial jump point of the Natters.

If the small universe is not pulled by the outside world, it will stay in one place forever, and the jumping point is fixed, and the practice of this undead creature has forced the Nats into a corner.

For a long time, the Nats did not dare to open the spatial passage and could not obtain supplies. As a result, a lot of equipment is aging and damaged, leading to some disasters that could have been avoided. There was even a famine.

After a long war, the population of the Nat people has plummeted from the peak of 10 million to less than 3 million.

The fate of the Nats has entered the most critical moment, and at the last moment of this critical existence, the Nats have to resort to the last resort. An antimatter annihilation bomb.

The Nats launched the most intense battle since the loss of the fleet, and 50,000 Nats were left to rush out of the space passage in 50 transports of various sizes. They fought a brutal battle with the millions of undead who surrounded the jump point, buying their companions five hours to plant antimatter annihilation bombs.

Yes, the Nats don't even have the ability to fire antimatter projectiles directly. Thousands of years of shrinking and self-enclosed life. Not only did it consume the ambitions of their ancestors, but also caused their manufacturing level to drop significantly.

They no longer have the ability to build large warships, and many large equipment and ships can only be repaired and continued to be used.

Even the last killer antimatter annihilation bomb can only be installed manually and activated with a delayed start.

Fortunately, their enemies are not advanced civilizations, otherwise they would not even be able to use this weapon of mass destruction.

In the end, only 20,000 of the 50,000 Nats successfully retreated into the small universe, and the matter annihilation bomb wiped out an area with a diameter of more than 100,000 kilometers at the exit of the jump into nothingness. The millions of undead creatures that surrounded the leap exit also disappeared along with them.

This immortal king who has not even left a name in history. And so he died.

Because under the command of the undead king at that time, the essence of all the undead creatures in the whole world was gathered, and the history of the undead creatures in this world even appeared a fault line because of this, many powerful beings disappeared, and many special abilities were lost.

It wasn't until much later that the undead slowly regained their vitality, forming the current pattern of the three worlds co-ruling one realm. However, the gap between these three world masters and the original undead king is huge, and even many intelligent undead creatures under the command of the undead king are far beyond them in strength.

Sibbins knew what the reason was, because the undead creatures awakened in that generation had a very high proportion of wisdom, and the more memory fragments of previous lives were preserved, some of the knowledge and abilities of many Nath ancestors were passed down through guò soul fragments.

The generation that is reborn after annihilation has fewer soul fragments left, and the quality is far less than that of the previous generation.

It's a pity that the Nats are not what they used to be, and what once hid in the small universe was the elite of the entire Nat fleet, the elite who undertook the revitalization of Nat culture. Today, it is a group of survivors who do not want to forge ahead, are content with the status quo, and survive.

From time to time, Sibbins would think that if the water source body left this galaxy back then, the Nats would not be content with the status quo and hide in the small universe and not come out, but step out of the big universe and use the technology and equipment left by their ancestors to re-operate, maybe they would have pulled up a powerful fleet long ago, and would not have been forced to this point by the undead who didn't even have warships.

After detonating the antimatter annihilation bomb, the Nat people also reached the point of exhaustion, because the annihilation bomb wiped out all the matter within a diameter of more than 100,000 kilometers, and if the small universe needed to replenish supplies, it would need to go back to more than 100,000 kilometers to collect the resources needed.

This made the already stretched capacity of the Nats more and more nervous.

On the one hand, there is a lack of materials, on the other hand, the threat of undead creatures, and there is not enough space in the universe. The rate of new births among the Nats has dropped dramatically, and some couples are even reluctant to have the next generation.

Over time, the number of Nat survivors has dropped from three million to less than 300,000.

However, with the decline of the population, the consumption of materials by the Nat people is not as huge as before, and at the same time, the space and so on have also been expanded, and life is not as difficult as before.

If all of them remained the same, these Nat people would be able to survive for at least a few tens of thousands of years until the resources of the nearby star fields were completely exhausted.

But disasters are particularly easy to favor the unprepared, and a disaster that is enough to destroy the entire small universe is quietly swept in, and the artificial sun in the small universe is about to be extinguished.

What provides energy for the small universe is a small artificial sun with a diameter of only 10,000 kilometers, which is attached to the purchase of the small universe, and also belongs to the fifth-level civilization creation.

This small sun does not have much power and does not have a long lifespan. Compared to those stellar objects that often have a lifespan of tens of billions of years, this artificial sun has a pitifully short lifespan, only 50,000 years.

But for celestial bodies, it is as short as an instantaneous lifespan. For the Nath people, who have a lifespan of only three or four hundred years, it is a bit outrageous, and since the start of the artificial sun, the Nath people have multiplied for an unknown number of generations.

In their father's generation, the artificial sun has already reflected their lives, their grandfather, their grandfather. For generations, I don't know how many people have lived under the light of this artificial sun, and it is a matter of course. Many people would think that the sun's rays would shine forever.

It's a pity that artificial suns have a lifespan, if it was the heyday of the Nats. It's completely technical. Fuel the artificial sun so that it will continue to burn for another 50,000 years. But today's Nath people no longer have the ability to refine fuel.

Since hundreds of years ago, the light of the artificial sun has gradually diminished, and in the next fifty years, it has been completely extinguished.

Without the heat and light emitted by the artificial sun, the small universe would be dark and cold. It is no longer suitable for carbon-based organisms. If you have to live in it, it's to maintain the living environment. The resources required will be several times greater than they are now.

If that's the case, it's better to move out of the universe and move to a place where the light of the stars can shine directly.

However, the loss of the fleet, the level of civilization is declining, and at the same time, the Nat people who have lost their large-scale manufacturing capacity are also dead ends when they move out of the small universe to face the threat of undead creatures.

The former Nat people moved a mothership into the small universe, and now this powerful warship is only an empty shell, and the equipment inside has long been scrapped, and now, they don't even have the ability to sail away from this galaxy.

If this continues, after fifty years, the artificial sun will be completely extinguished, and the Nats will have to wait for death.

Sibbons was always looking for a way to save the Nat, and even considered reincarnating some of the Nats into the undead if necessary.

But because of the long-term hostility, the Nat people are very hateful to the undead, and on the other hand, the undead are too ugly, dirty and smelly.

Think about it, after tens of thousands of years of not taking a bath, or resurrected from a decaying corpse, you can imagine how terrible the appearance is, even if there is no feud, a creature with a normal carbon-based aesthetic will not want to be something like that.

In desperation, Sibbins could only think of another way, and the appearance of the human fleet gave him a new hope.

When he saw the human fleet, Sibbins found that the style of the warship was very similar to that of the Natts, and that different species could not develop similar styles because of their sizes, and that of the companion civilization of the water source body, their warship styles were very different from those of the Nats.

The similarity of the style of the guide zhì is likely to be that this human fleet evolved from the same species as the Nats.

After observing the armor and airship, Sibbins also confirmed this suspicion, and it was not until he saw Zhang Qifan, a human who clearly belonged to the same species as the Nat people, that he finally made up his mind and asked Zhang Qifan for help.

"300,000 nats are on the verge of extinction, for the sake of the same origin and species, please reach out and save us." Sibbins said sincerely.

It turned out that the scene in Darlad's memory of the black ball was released by the Nats in order to destroy the undead king, and it turned out that in this world, the civilization of the undead creatures was so low, because they were wiped out once.

Under Sibbins's narration, Zhang Qifan finally figured out these questions that had been haunting his heart.

As for the existence of the small universe, it reminded him of the dimensional crystal necklace he got in the box before.

This kind of space creation must reach the fifth level of civilization or above before it can be manufactured, and it is not uncommon for an individual of the Nath people to have a dimensional necklace, and then exchange a small universe.

This is a small universe, a big killer for large-scale transfer of materials and troops to reduce the cost of long-distance transportation.

For nothing else, just for the sake of this small universe, Zhang Qifan decided to get it at any cost. As for the 300,000 Nat who need him to save? Zhang Qifan didn't pay much attention to it.

"What kind of help do you need?" Zhang Qifan asked.

"We need a lot of nuclear elements, a warship that can go on a long voyage, some maintenance tools, etc." Sibbins tentatively made some demands.

"Nuclear elements? Are you ready to restart the artificial sun in the small universe? Zhang Qifan asked.

"Yes, the demand for nuclear elements is relatively high, is that okay?" Siebbins cautiously asked that even a small artificial sun requires hundreds of millions of tons of nuclear elements, and Sibbins felt very embarrassed to come to him and ask for such help without knowing him.

Zhang Qifan pondered for a while, looking very embarrassed, and only after he had satisfied Siebbins's heart did he say: "It should be no problem, there are just two energy-harvesting ships in my fleet, and you can collect nuclear elements by transforming them, but what can you use in exchange for my help?" ”

This is a big problem, you can't help the Nats for free, right? Sibbons certainly wanted to get help for free, but it was impossible to even think about it on his toes, and even if there was an energy harvesting ship, the collection process would have a cost. Not to mention the same origin and species, even if it is his own brother, he does not dare to make such an unreasonable request.

But what can the exhausted Nats give in exchange for their help? Sibbins couldn't think of it for a while, so he could only say, "I'm going to go back and ask first." (To be continued......)
