"Professor, the planetary mining project has been successfully completed."

Electronic synthesized sounds sounded in the laboratory, interrupting Lu Yongchang's immersed writing.

"Is it done..." Lu Yongchang raised his head and glanced at the holographic clock on the wall, with a hint of confusion in his eyes, "It's quite fast."

"Where is Kepler 452c? Has it been destroyed?"

"Yes, there are currently only five planets left in the Kepler 452 star system." Zero responded quickly, and at the same time showed the explosion scene of Kepler 452c on the holographic projection.

"How is the working status of the gravity compensation ship?" Lu Yongchang asked Zero as he walked towards the porthole next to him.

As a member of the stellar system, Kepler 452c suddenly disappears, which is bound to have a certain impact on the operation of other celestial bodies in the stellar system.

By then, Kepler 452b may encounter a lot of "trouble" wherever humans live.

For the current human civilization, it is almost impossible to completely eliminate this influence.

But minimizing this negative impact as much as possible is what human civilization can do.

The gravity compensation ship was built for this purpose.

With the help of several large-scale gravitational field generating devices, it can generate a gravitational field with a strength similar to Kepler 452c.

As long as it continues to orbit the original planet instead of Kepler 452c, most of the negative effects caused by gravitational disturbances can be weakened or even eliminated.

"The operation is in good condition." Zero's response came from behind, "No abnormal celestial body operation conditions have been detected in the star system so far."

Lu Yongchang nodded slightly, placed his hands on the edge of the porthole, and turned his gaze to the original location of Kepler 452c.

In the dark universe, there are scattered red and purple lights shining.

That is the light of molten iron and high-energy laser mixed with each other.

This is the final statement to the universe from a planet that has existed for billions of years.

Just as Lu Yongchang stared blankly at the flickering lights, the electronic synthesized sound sounded again.

"Professor, Academician Wang Man sent a communication request, are you connected?"

Lu Yongchang came back to his senses, glanced at the holographic projection behind him, nodded and said, "Put it through for me."

The next second, a big face full of wrinkles appeared in front of him.

Looking at this big face full of joy, the corners of Lu Yongchang's mouth slightly raised, and his mood felt a little better unconsciously.

"It seems that Academician Wang is very happy."

"Hey! Professor Lu, what are you talking about?" The smile on Wang Man's face grew stronger, "What a great harvest, Professor!"

"Kepler 452c directly fills the gap in the fleet's basic metals. Not to mention the current ring-shaped residential station, even another giant structural project will be fine!"

Lu Yongchang looked at Wang Man with a bright smile with interest: "Is this true?"

Hearing this, Wang Man felt his heart skip a beat.

Before the smile on his face dissipated, Lu Yongchang said: "Just in time, I have a giant structural engineering project here."

"I will ask Academician Tang Hairong to prepare in two days."

"Ahem...Professor..." Wang Man showed a slightly embarrassed smile and asked in a low voice, "Can I ask what type of megastructure project it is?"

"Of course." Lu Yongchang said lightly, "It's what we made before."

"Planet Fortress, are you impressed?"

"thump!"

Wang Man sat back down in his seat.

Planetary Fortress!

It is no exaggeration to say that all the projects currently under construction in the People's Federation combined cannot match the resource consumption of that thing!

This, isn't this going to cost him his life!

At this moment, the smile on his face had completely disappeared.

"What's wrong, Academician Wang?" Lu Yongchang looked at Wang Man in front of him with a smile, and said in a teasing tone, "You were not like this just now."

Wang Man swallowed hard, raised his hand and gently wiped the cold sweat on his forehead, and said with a wry smile: "Professor, I just said it casually, Professor, please don't make fun of me."

Lu Yongchang looked at Wang Man in the holographic projection with a half-smile.

After a moment of silence, he said softly: "Who said I was joking?"

"After the starship replacement project is completed, the construction of the planetary fortress will be put on the agenda."

"It can be seen from the last war with the Botha civilization that although the planetary fortress consumes a lot of resources, the effect it can exert in an interstellar war is definitely not comparable to that of one or several starships."

"In the past, due to technical problems, the planetary fortress was only a semi-finished product."

"This time I want to build a true planetary fortress."

"At least, it has to move!"

"Hiss!!!" Wang Man took a breath after hearing this.

He silently made an extremely rough calculation in his mind.

In order to achieve the goal stated by Professor Lu, no matter what, we must add a power system to the planet.

This would require hollowing out the interior of the planet.

Simply hollowing it out will definitely not work. No matter what, various fixing and supporting devices must be installed inside. Otherwise, wouldn’t this planetary fortress become a hollow stone shell?

When the time comes and it breaks into pieces when touched on the battlefield, it will become a big joke!

Coupled with the weapon system and defense system...

After finishing the calculation, Wang looked at Lu Yongchang with a despairing face: "Professor, we...we don't have that many resources!"

"If you don't have resources, just mine them on site!" Lu Yongchang looked at Wang Man in surprise, "You don't have to use such a useful resource mining method, why don't you just watch it?"

"No, that's not the problem..." Wang Man's expression became increasingly bitter, "Except for Kepler 452b, there is only one rocky planet left in our star system!"

"According to the detection report, this rocky planet is not rich in mineral resources. If it is really mined, it may be a loss-making business."

Lu Yongchang was even more surprised when he heard this.

"Who said it's in our star system?"

"Ah?" Wang Man was slightly startled, with a look of confusion on his face.

"The curvature detector sent out some time ago has successfully returned the detection report." Lu Yongchang smiled and transferred a file to Wang Man opposite the camera, "According to the detection report, in the star system 6.71 light-years away from us

, has three iron planets and two rocky planets, and is quite rich in metal mineral resources.”

"Moreover, the detector did not find any traces of the existence of alien civilization."

Wang Man suddenly realized.
