After Fang Zheng took away the reorganization machine, perhaps the missionary also knew that he could not do anything, so he also decisively withdrew his troops and chose to retreat. Soon, Fang Zheng saw that the Precursor battleship had opened the jump space, and then ran away with the remaining Star Covenant fleet.

"All the sea fog obeyed and immediately jumped to Requiem while preparing for the next move. Iona, send a stealth scout to follow the missionary, don't lose its place. ”

"Understood, I'll send Leander to investigate."

"Good."

Hearing Iona's answer, Fang Zheng nodded in satisfaction, and then waved his hand.

"Everyone is ready to go, the goal is ......... Requiem!! ”

Soon, the Sea Mist fleet quickly turned into beams of light and disappeared into the depths of the universe, leaving only a stunned group of researchers in the research station.

And a pennant and five hundred dollars.

Previously, through the jump coordinates, Fang Zheng had learned that the missionaries had not returned to Requiem, so he took this planet for himself as a matter of course. Anyway, the original owner of this planet, the forerunners, are all dead, and since it is a borderland, then whoever sees it is whom?

I'll come, I'll see, I'll conquer.

After "returning" to Requiem, Fang Zheng immediately began to carry out the next work, he first found several scientific research ships such as Neptune, and some warships were responsible for researching and eating the entire Precursor technology with Iona on Requiem, on the other hand, Fang Zheng also sent another part of the sea fog warships to other shield worlds to "dig graves and rob graves", because there are communication channels between each shield world, so Nimfu quickly locked the location of those shield worlds, so Fang Zheng let these sea fog warships form a team of threes and twos, Explore the other shield worlds separately.

If there are humans or Covenant activity in those shield worlds, don't care, if not......... Hey, hey, hey......... You know.

The Sea Mist Battleships were also quite excited about this, after all, when Fang Zheng "adopted" them, he promised to let them go to the Star Sea for adventure, and now, they finally came to the Star Sea, naturally they were extremely excited. Except for a few warships such as Unicorn that stayed on Requiem to be in charge, after Fang Zheng assigned the task, the other Sea Mist warships suddenly couldn't wait to sneak away.

It was only at this time that Fang Zheng finally had time to start thinking about some questions that he hadn't thought about before.

"So......... Nimfu, you mean that the shield world was used by the Precursors for refuge? ”

"Yes, master."

Sitting in front of the console, Nimfu nodded as she quickly collected and packed the Precursor's technical data.

"According to the records, the Precursors were there to deal with the Flood Demons, but it was originally due to the invasion of ancient humans........."

Under Nimfu's introduction, Fang Zheng finally understood the entire background and ins and outs of this world.

And all of this has to start with the pioneers.

According to the historical records of the Precursors, the Pioneers are the most powerful civilization in the galaxy, and they are responsible for spreading life and civilization in the galaxy, and completely destroying the "losers" among them. The Forerunners are also one of the civilizations created by the pioneers, and they will also be the next civilization that the pioneers will obliterate.

However, the Forerunner's technology level was only one level lower than that of the Pioneer, so he was naturally unwilling to sit idly by, so the Forerunner launched a surprise attack on the Pioneer before it was killed.

No one knows what happened during this period, the only thing known is that the Forerunners won the war and drove the Pioneers out of the galaxy——— Well, hearing this, Fang Zheng feels that this Pioneer does not seem to be as powerful as he imagined, of course, this is not easy to say, after all, according to the records, the Pioneers are better at creating, if they are composed of some powerful but scarce individuals, then it is not impossible to be killed by the Forerunners with crowd tactics.

This is the same reason why no matter how powerful the dragon clan is in the main world, it can't be the master of the world.

However, after that, the ancient human civilization began to develop, they had great wisdom, and through the study of the technology left by the pioneers to obtain a very powerful power, and then the ancient humans launched an attack on the precursors, at first the precursors thought that the ancient humans simply wanted to invade, so they launched a counterattack against it, and the war between the ancient humans and the precursors lasted for thousands of years, and finally ended in the complete defeat of the ancient humans.

The last hominins were genetically degraded by the Precursors and thrown back to Earth, and their creations were completely destroyed.

But after that, the Forerunners discovered that the real reason for the ancient humans' invasion of their territory ——— the flood demons.

This parasitic race is full of very powerful and terrifying powers, and it is precisely in order to fight them that the ancient humans have to invade the territory of the Precursors, and at the same time, due to the parasitic nature of the flood demons, the ancient humans must destroy their parasitic planet in all directions. This is another reason why ancient humans launched an attack on the Precursor planet......... However, the Forerunners at that time did not believe the words of the ancient humans at first, they believed that the so-called flood demon was just a primitive infectious disease, not as alarmist as the ancient humans said, they thought that it was just an excuse for the ancient humans to invade and destroy the Forerunners.

But by the time the Flood army appeared in front of the Precursors, it was already too late.

History repeats itself, and the ancient humans were defeated because they suffered heavy losses in the war against the Flood Demons, and finally they were unable to compete with the Forerunners.

Now, the Precursors, who had been severely injured in the war with the ancient humans, were also unable to resist the invasion of the Flood Demons, so the Forerunners had to start creating "Halos" as a final means of dealing with the Flood Demons. When the Halo is activated, it destroys and obliterates all living beings in the galaxy, including the Flood.

In order to preserve the biological samples of the galaxy, the think tank leaders of the Precursors began to build the Ark and the Shield World to avoid the extinction of the entire galaxy.

In the end, the Precursors lost the war against the Flood Demon and activated the "Aura", wiping out all creatures in the galaxy that were not protected by the shield world and the ring, and even the Precursors themselves, were completely wiped out in this catastrophe......... And this is also the origin of the shield world.........

"Shield World ........."

Fang Zheng raised his head and looked at the primitive and life-filled world in front of him, where all kinds of animals and plants could be seen everywhere, and this was another new world, a Garden of Eden.

However, Founder's consideration is more than that.

After learning all the ins and outs of the Precursors from Nimfu, Fang Zheng became extremely suspicious of the Overworld. Especially the "cage" he saw with his own eyes made Fang Zheng start to think about a problem.

Is the Overworld also a "shield world"?

Is its function the same as the "shield world" created by the forerunners in this world, which is used to preserve other biological samples?

If you think about it, the possibility is not only there, but it's quite large. After all, from any point of view, the species in the Overworld are too rich, and there is not much difference between many civilizations, such as humans, elves, dwarves, dwarves and other races, the gap between civilizations is not outrageous, and the dragons, devils and other advanced races that were originally enough to rule the Overworld have invariably chosen to escape from the world.

While the Devil's army occasionally plots to invade the Overworld, ......... It doesn't seem like they're really that concerned about it, either.

If it were on an ordinary planet, then this situation is difficult to understand, but if you think of the Overworld as a refuge......... It's a different story.

Moreover, unlike humans, dragons and demons have a relatively long lifespan, and they must know some ancient secrets about the Overworld, is it because of this that they did not attack the Overworld?

What exactly are they waiting for?
