After Xu Xingchen's order was conveyed, the Xinghai Alliance began the highest level of mobilization.

All ship girls received notifications that on-duty and attendance tasks were rearranged based on the existing tasks and organization.

After a month of preparation, the ship girl of 1.2 million was finally mobilized to join the two galaxies nearest to the solar system in advance.

Among the ship girls under the Star Sea Alliance, the native ship girls and the deep-sea transformed ship girls each have just over 1.2 million, totaling more than 2.4 million.

The galaxies controlled by the Star Sea Alliance are still too large compared to the number of ship girls of more than two million.

Various institutions that must be on duty at any time directly occupied nearly one million ship girls.

If it weren't for unlocking the new reproduction method, Xu Xingchen's ship-girl civilization would have less than ten galaxies at most.

If you want to continue to expand, you must absorb other civilized populations, or simply use Neptune's plan to transform animals into intelligent life and become servant races on a large scale.

Among the 1.2 million ship girls mobilized now, the deep-sea transformed ship girls accounted for nearly one million, and the native ship girls accounted for only more than 200,000, including all scientific research ships.

Because the native ship girl has a complicated background, she has undertaken practical work in various aspects in the original various ship girl organizations, and the administrative staff is also different.

It is better to directly draw most of the native ship girls out, and more low-level ship girls or deep-sea transformers to supplement them. This is better to directly draw the deep-sea transformers.

The ship girl who transformed the deep sea was completely the opposite. They were all transformed together, and it was relatively convenient to mobilize.

They have a very regular and unified administrative structure and do not undertake large-scale meticulous local management work. Most of them are concentrated training in the Three Islands as reserve fleets.

At the same time, more than two months after the solar system crystal warships fought, the crystallization disease on the earth has not been controlled, but has become more and more serious.

Not only are the infection and crystallization still continuing to explode, but deaths in humans and animals have also begun to appear on a large scale.

Social order in many areas began to collapse, and the original urban residential areas fled in a large number of purposeless escapes, and a large number of crystalline wreckages were abandoned on the cities and wilderness.

The situation on the entire planet is about to get out of control.

The detectors arranged by the ship girl in the galaxy around the solar system have never been discovered by similar objects of the crystal spacecraft.

The other party may not really come because the other party has indeed succeeded.

If it weren't for the special state of the solar system, they had actually been completely successful, and the earth would soon become a crystal planet.

Now, Xu Xingchen has only one way to go, that is, to enter history, time and space again, and use time and space to modify history simultaneously.

After more than two months of observation and analysis, a relatively complete summary has been formed on various details before and after the synchronization of time and space.

On the normal timeline of the solar system, the events recorded by the original unmanned spacecraft are still only the original historical events of the original time and space in the time before the moment of time synchronization.

Only after the time and space synchronization is completed will the unmanned spacecraft begin to record events in the synchronized world.

At the same time, the past record file information before the time and space synchronization moment will not change with time and space synchronization, and will still be normal records that were originally completed.

In other words, the original observers of the solar system will not see events in parallel time and space, and both sides are already in different worlds.

After the time and space synchronization, the synchronization event will only start recording the synchronization event, and it is still an event that occurs in the time and space where the unmanned spacecraft is located.

This is the case specifically on certain natural objects, such as the moon, Io, Pluto, and other single asteroids.

The ship girls transformed these objects in parallel space and time. For example, the ship girls dug a large pit on the moon in 1980 and built an underground base.

None of these operations will affect the original state of historical time and space. The moon in the original history will not appear strange pits and underground bases at the beginning of the 1980 record.

Only when time and space synchronization are reached, the state of these objects after being changed by the ship girls will merge with the original state of time and space.

Most of the results are the state changed by the ship girl, and the original prototype state is directly covered.

The pits dug by the ship girls and the bases built will appear directly on the merged historical moon at the moment when time and space are synchronized.

However, if an object disappears directly, it is completely consumed, or the state is completely changed.

For example, asteroids used as raw materials for spacecraft and artificial planets, after time and space synchronization, unconsumed objects in the old time and space will continue to exist.

Because the new time and space have completely disappeared, there will be no more things in which the new state covers the old state, but the old state will continue to be retained.

At the same time, the built warships and planets will be retained normally because they are completely new objects that will be directly covered as a whole.

If Xu Xingchen completely dismantled the earth into resources in a certain historical space-time and space-time synchronization, the transformed resources and the original space-time and space-time will continue to exist at the same time.

In other words, if historical influence is not taken into account, Xu Xingchen has more matter in the solar system for every additional parallel space and time.

On this basis, Xu Xingchen, ship girl, humans, spacecraft and other historical time experiencers and tools should also follow similar rules.

In a new parallel space-time ship girl, she will not see herself in the previous parallel space-time self, and will only be retained in the state of the new space-time after the time and space synchronization.

However, the relevant laws are still not very clear about the energy consumption level of each interference behavior and the energy consumption of the final space-time synchronous behavior itself.

So in order to avoid the earth being infected by crystal creatures, Xu Xingchen directly asked the planet warship girls to brush the time and space as close as possible to the current timeline to deal with the crystal spacecraft and potential creatures.

If the state of the entire earth and all living things is changed, this level of interference consumes extremely high energy, and the energy consumed by simple time and space synchronization is also extremely high, and it will be troublesome if all the energy in the superimposed space of the entire solar system is consumed.

If parallel time and space disappear directly, you will lose the opportunity to interfere with the history of the earth again, and the history full of mystery becomes the only reality.

More importantly, the entire ship girl civilization lost dozens or even hundreds of years of independent development and improvement, and at the same time it lost several solar system materials...

So Xu Xingchen finally decided to take as many ship girls as possible into the parallel and put the three goals together to achieve them.

Reduce the number of times of time and space synchronization behavior, while maximizing the use of time and matter in parallel space and space.

Space-time synchronization itself consumes not much energy. On the contrary, this kind of multi-threaded large-scale interference superposition operation will consume more energy.
