Chang Wei carefully read the mission requirements and immediately determined that this was a rescue operation in a large-scale fleet war mode.

According to his understanding, the "Nantianmen Project" seems to be a science fiction concept and has been elevated to the national strategic level.

Chang Wei wasn't entirely sure what the situation was, but it was said to have evolved from online arguments between bloggers born in the 1980s and those born in the 2000s.

The content is: compared with those born in the 80s and 90s, who has made greater contributions to mankind?

After a long argument, the two sides were evenly matched. Finally, the blogger directly launched a big move:

"Little brothers and sisters born in the 2000s, you shouldn't have been born. It was us born in the 80s and 90s who saved the world in 1999, so you could be born. Don't bother looking! There's no information online. Because after we fought the aliens that day, everyone's memory was instantly wiped."

"Children, thank us for your birth!"

The lethality of these pretentious words is even higher than "I dare to eat shit"!

Afterwards, countless netizens joined in and began to improve the story.

Finally, the entire event structure was clearly defined, coherent, and complete, with detailed data to support it. Thus, the 1999 Earth Defense War was born!

Then, based on this, various science fiction concepts evolved. The "Nantianmen Project" is one of them. It independently built an aviation science fiction IP and published a novel of the same name.

Regardless of whether the novel is good or not, it at least describes the rigorous blueprint and concept of future integrated aerospace combat.

Eventually, it was noticed by the country and later summarized into a national strategic plan, namely: the "Nantianmen Plan"!

The original purpose of the "Nantianmen Project" was to counter the possible threat of invasion from extraterrestrial civilizations and silicon-based life forms. It was expected that all deployments would be complete by 2043. By then, a comprehensive global strategic defense system would be formed, consisting of the large strategic aerospace platform "Luanniao," the aerospace fighter "Xuannv," and the tactical robot "Chengying."

Although the mission world released by the system has the same name as the "Nantianmen Project" and has many connections, there are still many differences!

According to normal development, by 2050, humanity would be at best at level one civilization. But the humans in this mission world should be at least close to reaching level 1.5 civilization, right?

But even so, I'm afraid they are no match for the Silicon-based Civilization Alliance.

Thinking of this, Chang Wei immediately asked the system: "System, how strong are the space battleships of this Silicon-Based Civilization Alliance? What level of civilization are they? How many are there?"

The system mechanically replied, "The Silicon-Based Civilization Alliance, full name: Keld Silicon-Based United Destiny Community. They are composed of one Level 5 civilization, 36 Level 4 civilizations, 207 Level 3 civilizations, and 1,064 Level 2 civilizations. All members of the alliance are silicon-based life forms. In their current universe, they have existed for 3.674 billion years!"

"They have been at war with the Carbon-Based Civilization Alliance for 150 million years. They harbor a deep hatred for all carbon-based life forms. In their continuous exploration and expansion of the universe, they immediately issue an 'extermination order' upon encountering a planet with carbon-based life. If they discover a planet with silicon-based life, they wait until it becomes a Level 2 civilization and then actively accept it into the Alliance of Civilizations."

"The solar system is located at the edge of the Milky Way, very remote. Generally speaking, it would not attract the attention of the Silicon-based Civilization Alliance."

"But the Level 1.5 carbon-based civilization they destroyed actually abandoned their home planet two hundred years ago and took the initiative to become a wandering starship civilization. The Silicon-Based Civilization Alliance, knowing the principle of nurturing a tiger, will bring disaster, immediately began to investigate its whereabouts, and then pursued it all the way, discovering the existence of the solar system and humanity."

"Currently, this pursuit fleet numbers approximately 3,000, and is composed entirely of warships from a second-tier civilization. Within the Silicon-Based Civilization Alliance, they are considered the lowest-level, small reconnaissance fleet. Therefore, if they trigger an alarm, they are likely to attract a large number of warships from third-, fourth-, or even fifth-tier civilizations."

"Host, please be cautious. This mission is quite difficult. We need to quickly help human civilization establish contact with the Carbon-Based Civilization Alliance and seek their assistance."

"Note: During the battle, if the host's warship is completely destroyed, the wreckage will be recovered by the system, and the corresponding warship slot will be vacated. The original warship crew will all be marked as dead!"

After hearing this, one can imagine how much pressure Chang Wei felt.

When you are in a position, you must do your job!

He simply could not accept the thought that his side might suffer heavy casualties.

"No, I won't allow this to happen. I'm the commander of their fleet, and I'm responsible for the lives of everyone on the fleet! We still have nearly three days to prepare, so we must make good use of it!"

Afterwards, Chang Wei looked at the mission points he had left and the three vacant battleship slots that had not been recruited, and his mind began to become active quickly.

He decided to go all in!
