The last star candidate is Nanmen 2B, which is a member of the triple star system of the Nanmen 2 galaxy.

She doesn't have an asteroid belt, so there are almost no meteors, comets, asteroids.

Even if there is an asteroid alien to the galaxy, it will be eaten by the big brother of South Gate 2A.

There are no resources in the asteroid belt, but there is a companion star called Nanmen 2A, which has more mass than the entire galaxy of other galaxies and can be slowly dismantled.

The closest distance of the two stars is 11.2 AU, and the planets in the orbit of about 1 AU around the star of Nanmen B cannot be stable for a long time in billions of years.

However, the stable time of tens of millions of grades is enough for me, and it is not a problem to slightly correct the planetary orbit every tens of thousands of years.

Nanmen 2A is larger than the Sun, has a shorter remaining lifespan than the Sun, and will become a red giant after more than 3 billion years, which will affect Star B.

But in fact, it doesn't take that time for me to dismantle all of her, at least to the point where she won't become a red giant.

After analyzing it like this, it seems that the stars in the binary star system of Nanmen 2B are much more suitable than the remaining single stars.

South Gate 2 is called the α Centauri in the west, which is a three-dimensional star system, which is the prototype of the three-body galaxy that appeared in the famous science fiction "Three-Body Problem".

The South Gate II galaxy is the Sun's neighbor in the universe, with a distance of about 4.37 light-years between the two sides, or about 277,600 astronomical units (solar-terrestrial distance).

The South Gate 2 in reality is very different from the three-body galaxy described in the three-body problem.

It is indeed a three-star system, but it is a very stable celestial system, and there is no three-star chaos problem.

Because of the popularity of "The Three-Body Problem", many people think of the unsolvable three-body chaos when they hear Samsung, and then think of the unsolvable era of chaos.

But in fact, the ideal state of the unsolvable three-body chaos problem almost does not appear in the real universe.

Only when three stars of comparable mass are also quite close together will the three-star chaos problem occur.

The problem is that in that state of chaos, three stars like that could hardly be born at the same time from the start.

In the early days, it was easy to merge with each other and become binary stars, or one of them was thrown out by a gravitational slingshot, leaving a stable binary star system.

The multi-star system in the real universe is almost always in groups of two, with three stars being 2+1, four stars being 2+2, and six stars being (2+2)+2.

Nanmen-2 is a typical 2+1 star system, which is usually expressed in astronomy as Nanmen-2 AB-C.

This means that the first two are a binary star system, and the second one circles around the first two.

South Gate 2A and B, two stars with similar mass, rotate around the center of mass of both sides at the same time, with an orbital period of about 80 years.

The closest distance between the two sides is about 11.2 AU, which is equivalent to the Sun to Saturn, and the farthest distance is about 35.6 AU, which is equivalent to the Sun to Pluto.

Nanmen-2C, also known as Proxima Centauri, is the closest exostar to Earth, orbiting at a distance of 13,000 AU from the center of mass of the two stars AB.

Southgate-2C is a red dwarf star that is much smaller than both A and B, with only 0.122 solar masses, equivalent to 128 times the mass of Jupiter.

It's like a weak single dog, watching a couple turn around from a distance, and it's a very stable system.

Because the distance between Nanmen 2C and Nanmen 2A and B is so long, that it is still not completely certain whether Proxima Centauri is orbiting AB at a speed of 500,000 years, or just passing around them in a hyperbolic path.

These data, Mu Feng has been viewed and compared more than once, and if there are no earthlings, the solar system is obviously the most suitable.

But since there are people on the earth, I don't want to go to the solar system for the time being, so I finally chose South Gate II.

Mu Feng told Xingchen about his final choice.

Xingchen smiled and asked:

"I thought you would choose to go straight back to the solar system...... After all, your philosophy is to actively intervene ......"

Mu Feng nodded:

"It's active intervention, but it's not the present and the past, our current technology is biased, some places are a few eras ahead of the earth, but there are also many places that are not much ahead of the earth.

"Let's first find a place to gain a foothold, adapt to the environment of the earth's universe, take our technology one step further, and then organize a fleet to go to the solar system."

Xingchen nodded slightly:

"I understand, then our goal is to determine the second B of the South Gate, I will start preparing now, and there are other things that you need to do.

"Although the final fortress has a strong energy barrier, it should be able to protect everything on the ground from any influence as it crosses.

"But this is the first large-scale crossing after all, and to be on the safe side, I recommend that everyone enter the inner space of the final fortress for a while.

"I have activated the natural circulatory system inside Fortress Star, and the environment and conditions of the internal living module will not be significantly different from the outside.

"It should be said that after leaving the door, without the use of special detection equipment, it is impossible to find out that it is in the interior of the planet."

Mu Feng nodded and said:

"I understand, I'm going to send a notice and beckon everyone to enter the inner living cabin together."

Xingchen nodded slightly:

"Okay, let's start preparing ...... together"

After Mu Feng and Xingchen jointly decided, they also released a message to notify all ship mothers and humans to enter the designated living module.

When the Star transformed the final fortress, it had left a number of specialized entrances to the main islands of the archipelago around the world.

Now, these entrances are all open, and more than two million ship mothers living on the surface of the planet, as well as more than 100 million human beings, will pass through these entrances one after another under the unified command of the headquarters ship mother and turn into the final fortress.

There are no problems at all with the safety, supply, and environment of the internal living module, and the ship's mother in charge maintains order during the transfer process, and all parts of the world can communicate without barriers, so there are no major problems.

The entire migration process lasted about a month, and after a month, all the humans and ship girls entered the interior of the final fortress.

On this morning, Mu Feng and Xingchen, as well as the high-level ship ladies of each headquarters, gathered in the core command room of the final fortress.

Multiple holographic projections and displays, respectively inside the final fortress, on the surface of the final fortress, outside the planet, around the stars, etc.

On all projections and displays, there is a huge countdown.

When the countdown reaches zero, the language instructions of the stars appear in the cabins where all the shipwives are at the same time:

"Multi-layered space barriers are being activated......

"The transcosmic engine is being activated...... Loading target data......

"The final fortress orbital velocity is being adjusted to fit the target orbital ...... of the target star system"
