The Fourth Plague and Her Civilization

From the moment humans sailed toward the sea of ​​stars with technology, their territory spanned countless stars in a very short period of time. There is a split between a group of people who advocate peaceful expansion and explore existing resources to continuously develop technology and a group of war fanatics who constantly wage war against other interstellar civilizations. A thousand years after breaking out of the earth, mankind split into two civilizations - the Human Plural Republic Federation and the Interstellar Human Alliance. Referred to as the People's Alliance and the Star Alliance. But the protagonist of the story to be told today does not belong to the territory of these two civilizations. In the Alpha Arm of the distant Cygnus galaxy, an unknown civilization resides here. The civilization calls itself the Holy V Empire, and it still uses the most backward and inefficient imperial system in the interstellar era. The Emperor of the Empire, whose true identity no one knows, has been ruling the Empire from behind the scenes for thirty thousand years. No pity, no appeasement, just war and plunder. Because all suffering and atrocities are her game. The Emperor of the Shengwei Empire, a tyrant with no mercy in his heart. Likewise, he is also a sage monarch who spreads the light of civilization to every corner of the universe. Very important to read: The heroine is a player of P Club. Under the premise that everything is data, she will not have too much humanity towards NPCs, and she can do genocide and cleansing of civilization. Although the title is The Fourth Natural Disaster, this is actually the identity of the heroine, and this is not a fourth natural disaster article. It can be regarded as a behind-the-scenes flow, with a lot of infrastructure content and setting explanations. The core cool thing is complete control over civilization. Purely self-produced creation, no MacGuffin-style main line. Intention: That is my civilization, that is my land. That's my star, that's my destination.
