This time, half of the entire ship girl group followed Xu Xingchen into historical time and space. The most important purpose was to use parallel space to develop a wave and strive to improve the overall level and even scale of the ship girl civilization.

Interfering in the history of the earth has become a secondary purpose. Even disposing of crystal spacecraft creatures and preventing the earth from being infected by crystals is only a secondary task.

After the mother star fleet was ready, Xu Xingchen took his 10,000 fleet fleet and left the normal timeline solar system in a depressed mood.

After leaving this time, I came in again, and I don’t know what era it was.

A few minutes later, Xu Xingchen's fleet arrived at the South Gate II Galaxy and met with the ship girls who had already arrived from the parent Galaxy.

Let the ship girl who can use planet warship warships to unfold the hull and join eight conventional planet warships to receive more than one million ship girls.

More materials needed for the operation have been installed on the ship girls' own hulls, and they can be used when they arrive at the historical place.

It took me about a week to load the ship girl and prepare for the operation.

Xu Xingchen, who was waiting for the news in the middle, solemnly issued a order to set sail after receiving all the preparations.

"Start! Target solar system! Jupiter's orbit!"

Twenty-four 1,000-kilometer-class planet warships simultaneously activated the super-time and space engines and jumped to the solar system four light years away.

The time and space in front of Xu Xingchen and the ship girls began to twist, and the familiar sense of falling appeared again. After about three minutes, the surrounding pictures also recovered again.

Xu Xingchen immediately heard the sound of the ship girls reporting the situation:

"The time and space leap has been completed, and I tried to contact the home star. The contact failed and there was no signal."

"The superluminal engine cannot lock other galaxies! Same as last time I entered."

“Steer coordinates are being confirmed to determine the timeline.

"The timeline has been confirmed, we are suspected to be in 1820!"

"1820... This is the early nineteenth century, two hundred years ago..."

"We want to live here for two hundred years?"

Xu Xingchen was also a little shocked when he heard the news. 1820 was the 25th year of Jiaqing, the last year of Jiaqing Dynasty, and next year is the first year of Daoguang.

The common map of the Qing Dynasty's successor in history books is usually used in this year's version.

This time is really a bit early. The Napoleon War has just been over five years, and Napoleon himself is still alive and will not die until next year. Queen Victoria has just turned one year old now.

But if you consider it from another perspective, in 200 years, let alone the entire history of the earth, even compared with the history of the entire human civilization, this period is still very short.

It is thankful to some extent that it has not been sent to primitive society to watch the development of human civilization for ten thousand years.

Moreover, for two hundred years, the intervention of the earth's history will not be as urgent and nervous as last time, and can develop steadily step by step.

You should be able to complete the historical shaping you want, and at the same time you can avoid those messy and unsolved mysteries.

Of course, this time I led a large number of ship girls into parallel space and time again, with the main purpose of developing their own technology and civilization, and interfering with history is only secondary.

So Xu Xingchen put the matter on Earth aside first, cleared his throat and comforted all the ship girls and said:

"Everyone doesn't have to be nervous. I have lived here for two hundred years, and there is actually no essential difference between living outside for two hundred years.

"Although you can't run around the galaxy universe, there will be no unexpected risks here. You can completely treat it as a paradise.

"So everyone should do whatever they should do. Make some renovations as planned, and then start building space bases, building conventional planetary warships, and building artificial planets..."

Due to the special identity, Xu Xingchen's words always have very good results. The ship girls quickly changed their mindset and became busy step by step.

This time, Xu Xingchen is preparing to relax development and directly build an artificial and livable planet, which will be placed between Mars and Earth orbits, as the mother of the ship girl in the solar system.

Xu Xingchen is preparing to be neighbors with the Earthlings.

Of course, it cannot be directly built on this track. The impact of that process on Earthlings is too strong.

Humans in this era have been able to directly see all the planets within Neptune through astronomical telescopes, and can even "calculate" the existence of Neptune.

If the ship girls slowly build a planet from scratch between the orbits of the earth and fire, they will directly subvert the cognition of the people on earth.

Therefore, the super construction site where the ship girls built the planet was placed in the Kuiper belt outside Neptune.

After the construction of the artificial planet is completed, it will be guided by planet warships and fly to orbits between earth and fire in the form of wandering planets.

With human astronomy logic, this phenomenon can be explained barely. Wandering planets can exist, and it can be considered a coincidence that it can be stabilized between earth and fire.

When human civilization develops to the point where it can enter space and launch probes to Mars, it will be able to directly reach the artificial planet built by the ship girl.

At that time, Xu Xingchen would no longer hide from the earthlings, but would lead the ship girl to communicate directly with humans.

From the standpoint and method of a higher civilization, we will take over and guide the earth's civilization directly and develop with the native human civilization.

With the experience of dealing with crystal spacecraft or creatures, Xu Xingchen's mentality towards humans and even all carbon-based life has changed unknowingly.

As long as it is a humanoid creature or even a carbon-based life, Xu Xingchen has the mentality of being willing to help, not to mention that the earth is still a real human native civilization.

In addition to building artificial planets, Xu Xingchen also plans to build at least 100,000-kilometer-class planetary warships and try to complete the construction of a 10,000-kilometer-class planetary warship.

In addition, a space defense array was built within the Kuiper belt and in the asteroid belt between the firewood orbits, to circumvent the entire solar system.

Install high-power gravitational interference devices to help Earth and Shipwoo's artificial planets shield all cosmic objects and ensure the absolute safety of Earth and Shipwoo's artificial planets.

Now Xu Xingchen and the ship girls' perception of cosmic threats has escalated from the destructiveness of the simple energy level to all possible potential impacts.

The number of more than one million ship girls is only huge enough that multiple construction sites can be started at the same time. Xu Xingchen and the ship girls decision team simply assigned tasks.

Four conventional engineering construction planetary spacecraft are specifically responsible for the main construction projects of artificial planets, and resource collection spacecraft are responsible for collecting construction materials.

Scientific research explores the spacecraft as a temporary operation command center and a data processing center for operations throughout the solar system.

The main combat spacecraft does not have combat missions, so it also serves as an auxiliary spacecraft to cooperate with large-scale mobilization of ship girls and undertakes the necessary resource and material transportation work.

The eight conventional planetary warships that can last are all responsible for planet construction and related supporting projects.

The construction of artificial planets was listed as the highest priority project by Xu Xingchen. The working standard is to change ships and not change conventional engineering ships, and strive to complete the construction of the planet's main body within ten years.

In addition, the construction of ordinary space bases, the construction of large space shipyards, the construction of large resource conversion bases, and the collection, reserve and construction projects of various facilities and materials prepared for subsequent ground or too honest military ports, if the assistance of planet-class warships is required, the 16 planet-class warship girls will be responsible for the responsibility of the girls, and will take turns to carry out the hull to cooperate in the construction.

Other conventional ship girls are divided into corresponding 24 large fleets based on the existing number of planet warships and planet ship girls, and take turns to work and rest.

More than one million ship girls gradually spread out throughout the solar system and began to busy construction of various planetary-level processes, and the scenes were very grand.

Even if human observation capabilities in this era are relatively limited, if the ship girl does not deliberately conceal and hide, it will soon be discovered by human astronomers.

Many of these projects involve celestial interference, which will affect the gravity and orbit of natural planets and asteroids.

Even if humans cannot see it directly, they will be disturbed by more and more calculation errors.

It would be fine if you could think of the existence of alien interference, but if you think it was your own observations and calculation errors, or even doubts about formulas and definitions, that would be a big trouble.

Therefore, when the ship girls are working now, they have an important requirement, which is to avoid direct impact and interference on the earth as much as possible.

Especially for planetary level gravitational changes and interference, planetary warships should be avoided specifically.

Of course, this concealment cannot be maintained forever, and there must be an explanation of the release of the past.

Regarding this, Xu Xingchen and the ship girls thought of an artificial planet. The artificial planet that was originally planned to be put into the solar system would have a great impact on the solar system.

Xu Xingchen used it as a wandering planet to accidentally enter the solar system, releasing all the interference and impact of the ship girl space project.

Astronomers on Earth believe that all the interference and impact caused by ship girls are caused by this wandering planet.

When they can discover more details and find unreasonable differences, it may be two hundred years later.
