In order to ensure the destruction of the planet as quickly as possible, it is calculated that each raid detachment needs to have at least 100,000 warships.

Coupled with factors such as possible battle damage during the period, the final number of warships for each raid detachment was set at 200,000 warships, and the 50 billion warships were organized into 250,000 raid detachments.

And at the end of the first main spiral arm, how many destroy the target?

According to the data, there are more than 5 billion stars above the end, of which more than 800 million have formed star systems!

Within these more than 800 million star systems, the number of natural life planets is close to 30 million, and the number of modified life planets has reached as many as one billion.

This is not too late, after all, these zergs survive in the space environment, so many non-living planets have also become one of their strongholds, and there are more than 4 billion such planets.

Therefore, the final conclusion is that the number of target planets in this operation is more than 5 billion, and the average number of mission targets per raid detachment is as high as 20,000!

Of course, the four major and fifth-level civilizations did not expect to be able to complete such a huge task in a few years, but were ready to start a war with the Zerg while destroying their war potential.

And in this battle with the Zerg, the four major alliances have all issued the alliance's general mobilization order, and they have all been prepared for continuous combat for a hundred years, or even hundreds of years.

However, all this has nothing to do with humans for the time being!

Humanity today is busy with three things!

The first thing to do is to clear the main arm of the entire Orion arm, and deal with it in the same way as the secondary arm, select the races with great potential to keep them and include them in their own subordinate alliance system, and the rest of the civilizations will be eliminated.

The second thing, the construction work of the Hangu Pass Theater, this project is relatively huge, after all, the task of Hangu Pass is to prevent the four major alliances on the main spiral arm, including the Xiao Alliance!

In order to achieve this goal, not only is the heavy troops stationed, but also the Hangu Pass is the center to lay a full 30 light-years of jump blocking equipment.

In this case, even if Hangu Pass unfortunately falls, the enemy will not be able to break away from the jump barrier zone for tens or even hundreds of years.

And with such time, the Federation will be able to complete the evacuation of all mankind.

As for where to evacuate? Naturally, it has to do with the third thing.

This last thing is a plan that Lin Zhen has prepared for a long time, and now the conditions are ripe for formal implementation.

And this plan is to "surround the city from the countryside".

As mentioned earlier, the Milky Way is a galaxy with twelve moons, including the Large Magellanic Galaxy, the Magellanic Galaxy, and the Urphyllium Galaxy.

These satellite galaxies are not as big as the Milky Way, and the stars are not as large as the Milky Way, but they all add up to a lot.

Take the Big Magellanic Galaxy, for example, which has 10 billion stars, about one-tenth the size of the Milky Way, and the same is true for other galaxies, ranging from billions to more than 10 billion!

If you take all of these galaxies, you will find that the total number of stars is not even less than that of the Milky Way.

And the most important thing is that the four major fifth-level civilizations do not have the means to travel to these satellite galaxies.

You must know that there are no wormholes in the Milky Way galaxy that lead to these satellite galaxies, and without passing through the wormholes, directly crossing the void region, it is simply not much different from looking for death.

But human beings are different, human beings who have mastered space teleportation technology, as long as they do not exceed 1 million light years, can reach it quickly, and it only takes seven minutes!

To this end, Lin Zhen plans to establish 12 expeditionary corps in the next 20 years to go to the satellite galaxies of these 12 galaxies to carry out preliminary exploration work.

After all, the Federation does not know how many civilizations exist in these twelve satellite systems, whether there are advanced civilizations or not, so it cannot send fleets to occupy them hastily, and the acquisition of intelligence always comes first.

Just when everything in the Federation was unfolding in an orderly manner, a piece of news quickly spread throughout the Federation.

Queen Elfi of the Io Federation announced her early abdication, and the next king of angels was combined by humans and angels, and the first male angel born, Lin Tian inherited!

Speaking of Lin Zhen and Bella's son Lin Tian, he is now 31 years old, well, it can't be said that it has been, according to the current human lifespan, it should be said that he is only 31 years old.

But Lin Tian is a household name in the Io Federation, after all, he is the first heir of the union of humans and angels, and he is also a legendary male angel and inherits the characteristics of angels!

Plus his parents, one is the leader of the Human Federation, and the other is the former leader of the Io Federation!

After so many strong factors are superimposed on one person, it is difficult to be obscure!

Therefore, in the Io Federation, there is no opposition at all to Erfei's preparation of Lin Tian, who is only 31 years old, to succeed to the throne.

Even in recent decades, the angels of the Io Federation have almost regarded their Federation and the Human Federation as the same civilization, and even the combination of humans and angels is no longer a few!

If it weren't for the fact that the current human population is only one-tenth of that of angels, the Federation has set up some obstacles in the marriage between humans and angels, otherwise, I don't believe that humans will be able to marry angels in no time!

At least for now, it's not time to completely open up the intermarriage between the two groups, otherwise what will you do with the human girl?

Or is it ready to open up polygamy?

In any case, it is not appropriate, and this problem can only be solved after the human population has gone up.

Fortunately, both sides are not in a hurry, the lifespan of angels is generally more than 10,000 years, and there is no hurry at all for dozens or hundreds of years of waiting!

Although the current average lifespan of human beings is only about 300 years, the second generation of genetic evolution drugs has made many breakthroughs, and once successful, the lifespan will not be much shorter than that of angels!

Therefore, this problem will be completely solved after one or two hundred years, and there will be no problems at all.

------

98 years in the federal calendar.

The Io Federation held a grand ceremony in its capital area, and Lin Tian officially ascended the throne as the king of angels of a new generation.

According to tradition, when a new king ascends the throne, he will announce his first decree, and Lin Tian is no exception.

However, after a minute, everyone present, whether angels or invited humans, was stunned.

No one expected that Lin Tian's first decree would be like this!

"I announce that the process of merging the Io Federation and the Human Federation will be officially launched, and I will lead the leaders of the twelve tribes to hold formal negotiations with the high-level of the Human Federation later!"
