Doomsday: Opening a Class of Infantry

It's a certain month in 202x. An alien microbial spore, researched under the guidance of a secret national laboratory, is accidentally leaked. Within weeks, it sweeps the globe, infecting 95% of the world's population with an unknown virus, and governments and militaries worldwide succumb. The apocalypse arrives in an instant! Lin Zhi, an ultimate office worker, activates and binds himself to the [King of War] system in his despair, receiving a starting bonus of a heavy infantry squad! The apocalypse descends, chaos reigns! While other survivors fight over a bottle of drinking water, Lin Zhi is already luxurious enough to take a bath! While other survivor bases are embroiled in infighting over unequal resource distribution, Lin Zhi's survivors have an endless supply of meat, sweets, and other necessities! Furthermore, by continuously completing system tasks, Lin Zhi's rewards gradually grow from an infantry squad to a platoon, a battalion, a company… even an entire army group, encompassing all branches of the armed forces! Only when Lin Zhi finally reaches the pinnacle of the apocalypse does he realize… Zombies, a biological apocalypse, are merely an appetizer. Natural disasters are far more difficult to deal with! Extreme weather events such as scorching heat and freezing cold are arriving one after another!
