After most of the meeting on the intervention of historical plans, Xu Xingchen and the ship girls determined the basic principles.

First of all, the direction of interference must have a positive impact, and it is as positive impact as possible on the entire human race. If it is difficult to achieve, then the positive impact on the nation or country will be considered.

Secondly, interference should be divided into several different types and categories, such as interference that is prone to leaving traces but has little impact on society, as well as comprehensive intervention that has a significant impact on the entire social science and technology culture, and should be implemented and recorded in categories.

Then, each time, there should be only one fleet to perform interference, and multiple fleets cannot be carried out to different eras at the same time, so as to avoid the influence of different interferences and make it difficult to clarify the cause and effect

Finally, we should start from the timeline that is as close as possible to the modern era and gradually advance in the opposite direction to the longer-term era. However, it will be very cumbersome to brush the specified timeline for a single fleet, so the scale of a single fleet should be as large as possible, so that after brushing the appropriate timeline, the interference test should be carried out as comprehensively as possible in a single interference.

In the next two days, Xu Xingchen took the ship girls together to continue to formulate detailed plans, first setting the target around 2008.

At the same time, a fleet of interfering fleets composed of tens of thousands of ship girls, with very comprehensive and powerful abilities were organized.

From scientific research and exploration, to electronic technology to information, from engineering and construction, to business administration and politics, from agriculture and industry, to ocean shipping and combat.

He is good at all skills in all aspects, and most ship girls can participate in combat, so security and combat are not a problem.

More than 10,000 ship girls can use space warships that start in one kilometer, and various warships, aircraft, bases, ports, and airport war equipment on the planet, which is no problem.

On this basis, there is also the all-round mothership Xu Xingchen, which can provide logistical support for the all-round military port-level marquis and serve as the planet-level combat command center.

In addition to being a warship, Xu Xingchen's system space is also filled with various facilities, equipment, materials, drawings, etc. required by the ship girl and the military port.

Xu Xingchen brought this fleet, and even if he went to colonize a planet, it would be enough.

The goal now is just to interfere with the earth, which is a complete overuse of talent.

However, considering that the earth is the native civilization of human beings, it is also another psychological parent star for Xu Xingchen and his own construction ship girls. It is not an exaggeration to pay attention to it no matter how much you pay attention to it.

Three days later, Xu Xingchen and all the ship girls who participated in the mission boarded the ten-kilometer-level planet hull of Yuanwang Seven.

Xu Xingchen stood in the command room of the planet's hull and said to the main ship girls around him with a smile:

"Although this task is serious, there is no need to be too nervous now, because the first step of the action is to brush the timeline, and we may jump repeatedly many times...

"Considering that the further the distance, the more time it takes to jump, the next time we leave the solar system, we will not return to our home star, but to the South Gate two galaxy closest to the sun.

"So, everyone can relax now. Neptune, you don't have to worry. I won't let you leave my sight. Then, Sister Qi, are you ready?"

The ship girl from Yuanwang No. 7 stood beside Xu Xingchen, and nodded with a smile as she listened to Xu Xingchen's nagging:

"It's ready, but I feel like Commander, you're a little nervous? You won't talk about regular tasks like this..."

Xu Xingchen is indeed a little nervous. After all, what happened next is actually equivalent to traveling through history...

After being exposed by Yuanwang No. 7, Xu Xingchen laughed dryly and concealed his embarrassment. When he wanted to continue saying something, the pictures on the surrounding screen had changed.

The cosmic background disappears, the distorted space-time appears, and the sense of falling is getting stronger and stronger, and the spacecraft has begun to cross time and space.

Xu Xingchen simply closed his mouth, curious and nervously enjoying the scene of the journey across time and space.

Time passed slowly, and the ten-minute journey of leap ended, and the cosmic background appeared again on the surrounding screen.

Xu Xingchen and the ship girls subconsciously breathed a sigh of relief. Many ship girls began to chat, and the hall became lively again.

Yuanwang 7 actively reported the mission progress next to Xu Xingchen:

"We have completed space leap and successfully arrived in the solar system. The hull is currently in the orbit of the moon and has begun to confirm the time through the star coordinates..."

After a brief pause, Yuanwang No. 7 said with a little disappointment:

"The basic confirmed time is about 1942, which is not within our target timeline. There is no need to forget the more specific time. Now I am going to go to the South Gate Two Galaxy..."

Xu Xingchen breathed helplessly, but these were all expected, so there was nothing to say. He looked up at the surrounding screen and prepared to continue to enjoy the scenery.

The other ship girls also had the same mentality, and they were waiting for Yuanwang 7 to set sail again.

But everyone waited for three minutes, and the surrounding environment did not change at all.

Yuanwang No. 7's somewhat puzzled voice rang in everyone's ears:

"Strange, it is impossible to lock the particles of the two stars in the South Gate Two Galaxies..."

Xu Xingchen was also stunned:

"Then try changing a galaxy? Tiancang Five? Tianyuan Four?"

Yuanwang No. 7 shook his head and said:

"I've tried it, but it won't work...I'll try to go back to my home star..."

Xu Xingchen still didn't care too much, and nodded subconsciously, waiting to continue to see the scenery.

As a result, after waiting for two minutes, there was still no movement. The ship girls had already started to discuss, and Yuanwang No. 7 also said in a little confused:

"The parent star cannot be locked... Could it be that my super-time engine has failed?"

Xu Xingchen and other ship girls suddenly became a little nervous:

"Is it really a malfunction? This is an unprecedented situation! I'll let other ship girls spread their hulls..."

Xu Xingchen immediately passed the Message Communication Channel and instructed the ship girl outside the hull of Yuanwang 7 to leave the hull of Yuanwang 7 to test the super-time and space engine.

As a result, bad news came one after another, and all the ship girls who went out to test could not lock other stars. To be more precise, galaxies, stars, and planets could not lock them.

The hall was already in chaos, and Xu Xingchen also looked around with a blank look on his face, muttering his guess in disbelief:

"It is impossible for everyone's engine to fail at the same time, so... are we... trapped in this time and space?

"The key is that in 1942, the United Nations Declaration had been issued, and important turning points in World War II were coming.

"If I want to get involved in World War II, it should start from 1936, at least from 1939..."

Yuanwang No. 7 is relatively calm:

"Commanders don't have to worry. We have other options to try, such as sub-light speed sailing away from the space-time boundary of the solar system's edge...

Xu Xingchen was stunned for a moment and said helplessly:

"This...the distance is a light year. We have to run for more than a year, and we may not be able to get out...

"I have a feeling that it may be my fault if we can't get out. After all, I am a little different from everyone.

"There may be some kind of triggering condition in this space. The unmanned spacecraft will arrive at the normal timeline, and the ship girl will enter different time and space. I may not be able to get out if I come in...

"But now there is nothing I can do. I can only do it if I die and let a fleet go over and test it."

Yuanwang No. 7 nodded slightly:

"So will the Commander and other companions go to Earth first now?"

Xu Xingchen nodded helplessly.
Chapter completed!
