Mend the Sky for the Common People

In the year 1644 of the Lunar Calendar, the sky collapsed. The eight alien races joined hands to conquer the capital of the Sun and Moon Empire, the mountains and rivers were shattered, and the emperor died for his country. Those who surrender will rise, those who resist will die. The generals of the empire put on foreign flags, the nobles sacrificed their cities and people, and millions of refugees rotted into bones in the wilderness. Everyone said - this world is over. Liu Yi didn't believe it. He is just an unknown hunter from a small border village. He has no huge power, no ambition to restore the country, and he doesn't even have a decent sword. The only thing he wants to do is to survive in this rotten world with his dependent sister. But fate took him on a path he had never imagined.
