After Helena left, the galaxy fell into an eerie tranquility. It's like the dark times before the Star Crystal Queen and the Titans King became the overlords of the river system.

Some of the most ancient civilizations still have records of that time, when the galaxy was like a chaotic primeval forest, and many civilizations waged wars with impunity, plundered resources, and destroyed species.

One of the most notorious is Zack, the demon god of the abyss.

Before Zack, the Zerg and mechanical beings took turns to fight, causing chaos throughout the galaxy. For these reasons, undead, zerg, and mechanical life are listed as the three major public enemies of the galaxy.

At that time, the way for the major civilizations to protect themselves was to hide themselves well, just like hiding in a dark forest, if anyone dared to reveal their location, it was easy to attract the hunt of predators.

At that time, the Milky Way was as dead silent as it is now.

Until the fall of the Abyss Demon God and the rise of the Star Crystal Queen of the Titans, this dark period will never return.

The Star Crystal Queen has established a shelter in the first and second spiral arms, the Titan King has established a shelter in the third spiral arm, and the fourth-level civilizations such as the King of Machines and the King of Flowing Clouds have also established shelters in their appropriate positions.

With these shelters as the center, order is slowly established from the beginning, and weak civilizations can also take refuge in shelters, and when they are weak in the early stage of development, they can get reasonable shelter.

Thanks to the establishment of order, various civilizations began to thrive, forming the current situation of a hundred flowers in the galaxy.

Humanity can be said to have caught up with a good time. If it is replaced by the chaotic and disorderly times before, when human beings were still in the first level of civilization. The desperate act of sending all kinds of information into outer space is simply the birthday boy hanging. It's a long life.

Compared with other river systems, such as Magellan, the galaxy is very lively, and the diversity of civilizations is very rich, but this liveliness has completely disappeared with Helena's departure.

Ordinary civilizations cannot detect such changes, and even some civilizations that have been paying attention to the movements of the river system for a long time cannot detect this change for a while. But from some major events, most civilizations have sensed the abnormal atmosphere.

The King of Flowing Clouds died, the King of Titans fell, the King of Steel's shelter was destroyed, the energy of the Ring Galaxy migrated, and the fifth-level Zerg disappeared ....... A series of major changes have dazzled and overwhelmed most civilizations.

Before they could see the specific changes, everyone chose to hide themselves. Minimize large-scale activities to prevent enemy snooping.

At this time, Zhang Qifan was flying out of the river system at high speed, and he was following the coordinate information given by Itafi. Go find the whereabouts of the Protoss.

The Protoss are the best race at creating, so their settlement is not in the interstellar material-rich river system, but in the empty extra-river space.

space outside the river system. Interstellar matter is very thin, and even light particles are extremely rare. There are simply no resources for a race to live. Just like the human world, the most dangerous thing is not the wild savannah. It's a desert as far as the eye can see.

In the galaxy, even the menacing Silver Heart has creatures living there, but in the space beyond the river, it is the world where life is truly extinct. Except for the Protoss, no other creature could survive there for long.

No one knows why the Protoss may be living in the space outside the river system, this is not as simple as a group of creatures bringing enough supplies to swim around the river system, but living there for a long time, multiplying, and developing civilization.

Some people speculate that it is because the Protoss has mastered the ability to extract dark elements from the void.

The vast majority of the universe is made up of dark elements, including space. Even if there is no air, no stars, no matter, there is still space in the void, and if the dark element can be extracted directly from the space, then there will be no more possibility of energy shortage.

What is the biggest problem with transgalactic sailing?

Naturally, it was the distance of millions of light years, Helena mobilized the power of the entire Magellan, and forcibly waded a material channel between the two river systems, which other civilizations did not have this ability.

Even the Star Crystal Queen, who has one of the best galactic coefficients, has already made her a rift expander, which has already damaged her vitality. The material passage between the galaxies requires hundreds of times more materials than the rift spreader.

If you can master the technology of extracting dark elements directly from space, then the distant river space will turn the moat into a smooth path, and any creature can use the void to continuously extract dark elements, and go from one river system to another, which is only a matter of time.

With this kind of technology, there is almost no need to worry about energy in the universe, because even if there is no matter, there will never be no space.

However, the stronger the Protoss, the less steady, Zhang Qifan's heart became unsteady, and even the Protoss, which had the power of creation and the technology of spatial extraction of dark elements, quietly disappeared, what kind of changes happened in this?

With a space jump, Zhang Qifan came to the galaxy at the very edge of the Milky Way. From this galaxy, beyond that is millions of light-years empty of extragalactic space.

Thinking of that long distance, Zhang Qifan felt hopeless.

With his current ability, the farthest jump distance at one time is 300,000 light-years, which sounds quite far, right? One jump can span the entire galaxy, right?

However, it is useless, after a jump, his strength will be exhausted, and there will be no strength to go forward, let alone return. And the space of the river system 300,000 light-years away was empty, and he didn't even have a place to replenish his energy.

If you can bring a small universe and stuff it with supplies, maybe it is a feasible way. However, as mentioned above, the movement of the small universe is not the small universe itself, but the passage in and out of the small universe.

What if I arrive in the space beyond the river and can't open the small universe? If this happens, the price to pay will be lives.

Fortunately, the settlement of the Protoss did not exceed the limit that Zhang Qifan could reach, it was only about 100,000 light-years away from the river system, and he not only had the ability to go, but also had the strength to come back.

What are the benefits of the Protoss living in the outer space of the river system?

First of all, it is naturally safe, the empty space outside the river, any high-intensity energy fluctuations, can be transmitted very clearly and far away, and the enemy can be seen at a glance as soon as he approaches.

The second is that the Protoss likes to be quiet. (To be continued......)
