Stars, Starting with Billions of Zombies

Mechanical natural disaster: When several robot empires appear in the universe, it is possible that their thoughts will unite into one and wipe out any non-mechanical life forms. High-dimensional invasion: High-dimensional creatures descend from the high-dimensional universe using spiritual and physical means, destroying everything and turning it into nutrients. Void Zerg: The interstellar Zerg is expanding rapidly, and any cosmic force that blocks their progress will collapse under their attack. These three types of situations are defined by cosmic civilizations as natural disaster-level annihilation crises. But all this has nothing to do with Qi Ming, at least not for the time being. What is bothering him now is another problem. How to defeat a city besieged by billions of zombies? Urgent, waiting online. After that, the fourth natural disaster was born!
