I built the underground Noah's Ark

Chapter 183 Definition of a Habitable Planet

May of the fifth year of the new era.

A message reached the Nirvana Command.

The Puzhe Civilization has prepared a thousand interstellar warships and is conducting intensive drills.

This news comes from Chang Guangxiong, who is resident in the Star Alliance, and Mao Xiaonan, who is temporarily living in the Sage Star.

Mao Xiaonan's source of news is completely different from Chang Guangxiong's.

This also proves that this news is reliable.

In another piece of news, after Chang Guangxiong's mediation, the Star Alliance decided to go to Blue Star again for a technological review three years later.

This review will determine the future of Blue Star.

Chang Guangxiong specially emphasized that the real murderer must be caught before the technology review officer conducts another review.

Otherwise, this technology review will be extremely detrimental to Blue Star.

"The news is confirmed?" Zheng Jicheng, the commander of the space force, looked extremely serious.

The current human space force has only one framework.The first space battleship has not yet been built.

There are only two human developments in space now, one is to build space elevators, and the other is to build space ports.

These two projects can really only be counted as one.

Because the end of the space elevator is the space port.

Human beings adopt the mode of space elevator plus space port adopted by most planets.

After nearly five years of construction, the human space elevator has just been completed, and the space port is also under construction.

This has consumed a lot of human resources.

Therefore, up to now, the Blue Stars have not built a space battleship.

"It's confirmed." Ye Linsheng said solemnly, "After many inquiries, the Puzhe Civilization has withdrawn thousands of warships from other battlefields, and they are now returning to Hong Kong for repairs. Just to block our civilization."

"Don't you care about the Star Alliance?" Although Zeng Lao is old, he is still emotional, "Then what's the use of the Star Alliance?"

Ye Linsheng sighed: "The Puzhe civilization is a well-known rogue civilization. They use various methods to search for resources in the universe. There are more than a dozen planets occupied by them, and these planets are actually the same as our Blue Star. There are indigenous civilizations. But they used the method of terrorist creature invasion to wipe out the indigenous civilizations, and then occupied them in the name of the unowned planet."

"Moreover, there are still seven or eight planets that have been actually controlled by them through infiltration. They have nearly ten votes of voting power in one civilization. Most importantly, they have also obtained the support of two super civilizations. acquiescence."

Ye Linsheng took a deep breath: "This battle is unavoidable. We must actively face it."

Mao Xiaonan and Shu Ziyuan successfully settled down in the civilization of the sages by using their proficiency in the language of the sages.

These news were obtained by Mao Xiaonan and Shu Ziyuan through various means.

The means of Puzhe civilization have also been criticized in the Star Alliance.

But because of the ambiguous attitude of the two super civilizations, these criticisms are useless to the Puzhe civilization.

They have suffered a great loss from the Blue Star civilization this time, and with their character, they are absolutely unwilling to let it go.

The invasion of Puzhe civilization is inevitable.

Fighting is the only way out for mankind.

"How to fight?" Zheng Jicheng said with some complaints, "We don't even have a warship. We don't even have the construction materials for the warship."

"Mao Xiaonan is in contact with the senior management of the sage civilization, hoping to buy a space battleship from the sage civilization." Ye Linsheng looked up at the sky, "I hope she can succeed."

Humans know next to nothing about the functions of space battleships.

I don't know much about the combat system of the alien fleet.

Luo Ji suddenly said: "Didn't Mao Xiaonan say that the Puzhe civilization is now fighting a planet that has just escaped the protection of the indigenous civilization. Let's take a group of military and scientific experts and go quietly to see it?"

Ye Linsheng's eyes lit up: "Good idea. Only by knowing yourself and the enemy can you win every battle. Inform Lu Yingdong and get ready to go."

……

On the Sage Star tens of millions of light-years away from Blue Star.

The 20-year-old Mao Xiaonan appeared at the foot of a tall building with short hair.

Several members of the opposite sex who came over cast appreciative glances at her.

The similarity between the sage star and the blue star is as high as [-]%.

Mao Xiaonan walks here, no one treats her as an alien, but just treats her as a sage with a bit of exotic style.

And this exotic style has also attracted people's attention.

She is now a diplomat stationed by Blue Star Civilization in Sage Civilization.

In the past two years, based on the information sent back by Mao Xiaonan, Blue Star has searched for dozens of peaceful and sympathetic civilized planets, and sent interstellar diplomats.

The mission of these diplomats is to expand the influence of Blue Star and win the support of civilizations on various planets.

Go into the tall building and enter the elevator.

Everything here is like a more developed Blue Star.

The elevator is very fast, and it only takes more than a minute to go up to the 56th floor.

Stepping out of the elevator, he saw his employee Gulina head-on.

"Director, someone from the Interstellar Affairs Bureau is here." Gulina said as she walked.

Mao Xiaonan smiled: "Very well, I'll go see him now."

Walking into the conference room, the interstellar affairs officer in a long gown stood up and stretched out his hand: "Miss Mao, next Ji Guangxi."

Ji Guangxi was in his thirties with a calm appearance.

Many cultural traditions of the sage civilization are extremely similar to the Blue Star civilization.

This part of self-introduction is almost exactly the same.

"Welcome, Officer Ji, have you read the application I submitted to you?" Mao Xiaonan sat down with a smile.

After two years of training, she is now a mature interstellar diplomat.

"I see. But to be honest, it's hard for us to accept." Ji Guangxi hesitated, "We have already agreed to the second-hand starship you bought from us. However, what you want to buy this time is a space battleship. This will affect our relationship with you. The relationship of Puzhe civilization."

A year ago, through his own efforts, Mao Xiaonan got Sage Civilization to agree to sell two second-hand starships at a price of [-]%.

Let Blue Star have three spaceships capable of interstellar travel.

This is a huge breakthrough in the history of Blue Star's interstellar diplomacy.

Now, Mao Xiaonan actually proposed to buy a space battleship, the nature of this is completely different.

Moreover, if you want to move the battleship to the blue star, you need to install an interstellar engine.

If the sage civilization agrees, it will be standing in line in disguise.

It is completely on the opposite side of Puzhe civilization.

It is obviously not in the interests of the sage civilization to choose to oppose the Puzhe civilization because of the Blue Star civilization.

Mao Xiaonan was not surprised, she smiled sweetly at Ji Guangxi: "According to our research, 3000 years ago, the sage civilization sent an interstellar spacecraft to investigate the solar system, but it crashed on the blue star due to an accident. The place where it landed happened to be the residence of our Blue Star civilization."

"According to our archaeological results, the pilots stayed in the Blue Star and merged with the Blue Star civilization. This can be found in our Blue Star's historical books."

Mao Xiaonan opened another document, which is the historical document of the sage civilization: "Look, this is the record of the sage civilization. 3000 years ago, at the same time, the sage civilization lost an interstellar spaceship. This The direction the spaceship is going is exactly the solar system, which is also the galaxy where the blue star is located."

Ji Guangxi frowned: "What do you want to say?"

"We are of the same origin. The Blue Star Civilization should be a branch of the Sage Civilization. Are you of the same race watching our Blue Star Civilization fall into trouble?" Mao Xiaonan stared at Ji Guangxi with burning eyes.

Ji Guangxi hesitated for a moment: "You also know that our sage civilization has always regarded itself as neutral..."

Mao Xiaonan smiled again: "Tell me, is there a possibility that the sage civilization sent a space battleship to the solar system for a friendly visit, but encountered the same danger as 3000 years ago and fell into the blue star?"

Ji Guangxi understood: "Let's come here first today, I need to report to my superiors."

"I'm waiting for your good news." Mao Xiaonan smiled again, the sweet smile made Ji Guangxi's heart beat extra violently.

……

In the centaur cantilever of the Milky Way, an interstellar spaceship appeared above a golden planet.

This spacecraft is the Interstellar No. [-] spacecraft of the Blue Star Civilization.

Also the best starship ever.

There are more than a dozen crew members on board, all of whom are Blue Star's high-level space force and construction experts.

Ye Linsheng and Luo Ji are also on this spaceship.

They came to investigate the interstellar war.

A space fleet of the Puzhe civilization is launching an attack on a habitable planet in the Sagittarius system.

In the universe, there are many habitable planets.

Every livable planet is a huge fortune.

The Star Alliance has several criteria for defining habitable planets.

The first is size.

The habitable planet cannot be too small, and the minimum must have half the mass of the blue star.

It can't be too big, at most it can only be five times the mass of Blue Star.

Too big and too small are not conducive to the development of civilization.

It is almost impossible to develop advanced civilization.

A livable planet must have an atmosphere and sufficient oxygen.

In addition, there must be a water source.

If these conditions are met, it is basically a livable planet.

In the Star Alliance, whether a civilization is strong or not is also related to the number of livable planets it controls.

For a livable planet, such as the size of Blue Star, a population of tens of billions is the optimal number.

The more habitable planets you have, the higher the population.

And the larger the population, the more talents.

Correspondingly, the more developed, the stronger the strength.

Population is one of the most powerful criteria for judging an interstellar civilization, and it is also one of the most important indicators.

As the Haomiao civilization in the super civilization, it is said that it holds more than 1000 habitable planets.

The Puzhe civilization is also very strong. They directly control sixteen livable planets, plus nearly ten puppet planets, with a total population of more than 2000 billion. This is a medium-to-large civilization in the Star Alliance.

The Puzhe civilization, which claims to be the strongest civilization under the two super civilizations, has been expanding its territory.

They spent huge sums of money and sent a large number of interstellar exploration satellites to search for the existence of habitable planets everywhere.

The universe is so huge, and they never stopped their pace of conquest.
