Time passed in a hurry, because after the extinction of the Ramosi civilization, he had more than a hundred years of welfare blessing buff time, and there was more time to spare, so Lin Feng was not so eager to choose other civilizations of the same level to hunt.

Instead, they plan to climb science and technology and develop all kinds of weapons and equipment technology.

Three years passed in a blink of an eye, and Lin Feng traveled back and forth to the three world tree systems touched by the Immortal Civilization during this time.

The mechanical source realm is located in the multiverse wall, and each world exists in the form of a plane, and between the planes is an endless deep void, and very little matter exists, unless it is a dead plane, you can see a little matter around it.

The Immortal Civilization is also unremitting in the exploration of the multiverse wall, and countless exploration ships and space rovers have been sent to different directions, looking for the life plane in the multiverse wall.

Lin Feng, the universe where the earth is located, has also sent some exploration ships and space rovers to explore, but the scope is limited to the Milky Way, because the erased shadow of the Ramosi civilization star field has not disappeared, and Lin Feng does not want to encounter such an existence again.

Finally, there is the Star Sea Universe, where the Immortal Civilization has the most concentrated forces, the four major experimental planets, more than a dozen civilization zoos, and countless resource galaxies, all of which are the results of the operation and development of the Immortal Civilization in the Star Sea Universe.

However, after all, the Star Sea Universe is a complete world tree system, and the internal enormity is something that the Immortal Civilization cannot explore to the end now.

The Immortal Civilization is nothing more than a star field that occupies a corner of the Star Sea Universe, whether it is an experimental planet or a civilization zoo, it is located in this star.

However, it is the resources and materials provided by this star field that can support the advancement of the immortal civilization to the category of second-level civilization, and what is still missing now is that the scientific and technological strength has not yet accumulated to the advanced level.

Lin Feng was not in a hurry at the moment, because now the Immortal Civilization Index had reached 94 points, and he was about to enter the second-level civilization category.

And these are all relying on welfare blessing buffs, in the short period of three years, the Immortal Civilization has achieved very significant results in many scientific research projects.

Astronautics has also moved from curvature to faster-than-light travel, and researchers are now working scientific research projects on time-space jumps.

However, Lin Feng thought that the time-space migration might be a technology that could only be reached by second-level civilizations, but because of the existence of the welfare blessing buff, the enthusiasm of this group of scientific researchers for research has not diminished at all, and Lin Feng has not stopped it.

Nanorobotic insect technology has begun to be expanded, and these technologies have been enjoyed by researchers, scouts, managers, and newborn authors.

That is to say, this group of authorities can nanoscale their bodies, and even self-replicate by devouring resources, but there is only one tinder matrix, so even if they are self-replicating, the copy is just a shell.

However, these nanomechanical insect technologies are indeed a very practical technology for those in power in wars like War 1, and if they are injured on the battlefield, they can completely repair themselves by devouring resources and materials.

Moreover, now these nanomechanical insect technologies are developing towards all the creations of the Immortal Civilization, and in the future, it may be possible to achieve that all the creations of the entire Immortal Civilization can be instantly transformed into a nano state, and can be instantly reassembled together to restore their original state.

Lin Feng came to the EX-3 experimental planet, this experimental planet specializing in dark matter research has overcome countless problems in the past three years, the advanced negative matter cannon of the antimatter cannon has also been successfully developed, and the tachyon shield has also been successfully developed the year before last, and now it has begun to be popularized to warships and war robots.

After Lin Feng finished checking the EX-3 experimental planet, he went to the EX-4 experimental planet to check it out, and then came to the branch mechanical planet that was set up in the Star Sea Universe three years ago.

Dawn Mechanical Star, this is the name given to a planet by the Immortal Civilization after it was transformed into a mechanical planet three years ago.

Three years ago, a scout and a space-wanderer sent information that the four legendary civilizations that had never appeared in the Star Sea Universe had been operating abnormally during this time.

In the depths of the deep sea of stars, there will be terrifying fluctuations from time to time, and it may be that there is a war between these four legendary civilizations.

Among the four legendary civilizations, there is a guardian of the Holy Land that Lin Feng does not want to face.

In order to deal with all the turmoil that may occur in the Star Sea Universe, the Immortal Civilization immediately decided to establish a branch mechanical planet in the Star Sea Universe - the Dawn Mechanical Star.

Now the Immortal Civilization can also determine that the Guardian of the Holy Land should be at the peak of the second-level civilization, the kind of terrifying existence that may enter the third-level civilization at any time.

And the remaining three legendary civilizations are almost the same as the guardians of the Holy Land, and these four legendary civilizations are the most powerful existences in the Star Sea Universe.

According to some clues, it can be known that the Star Sea Universe actually had many third-level or even more terrifying existences before, but after an unspeakable disaster, only these four key technologies were lost, and the lost civilization was hidden.

These four legendary civilizations are called Lost Civilizations by the indigenous civilizations in the Star Sea Universe.

Lin Feng actually knew that the Immortal Civilization was like an ant in the eyes of the Guardian of the Holy Land, but he still unswervingly set up the Dawn Mechanical Star, because the Star Sea Universe was too important to the Immortal Civilization, and many resource planets and experimental planets were set up in the Star Sea Universe, and they couldn't be put down at all.

And Lin Feng also considered that it was a bit unwise for these important projects to be set up in the Star Sea Universe, and he was diverting to some of the star fields that had been recently discovered and developed in the Milky Way.

But it takes time, and Lin Feng of the Star Sea Universe really doesn't want to give up, the purpose of setting up the Dawn Mechanical Star is to take precautions, although it feels like it may not be of much use.

In addition to the Guardian of the Holy Land of the four legendary lost civilizations, the other three Lin Feng thought that he had not provoked others, and they would not come to trouble the Immortal Civilization, the most feared thing was that the Guardian of the Holy Land still remembered the Immortal Civilization and came out to erase all the assets of the Immortal Civilization in the Star Sea Universe, which was sad.

Of course, if the Guardians of the Holy Land have forgotten the Immortal civilization, then it will be the best case scenario.

However, with the frequent appearance of these four legendary lost civilizations, conflicts continue to break out between each other, and those space-level indigenous civilizations can't bear it, and begin to look for a lost civilization that suits their own type of civilization to take refuge in the past, willing to become a lackey of the lost civilization, and fight with other lost civilization lackeys.

And the scope of this spread is even greater, and Lin Feng also has this consideration in setting up the Dawn Mechanical Star.
