Zombie Apocalypse

The Republic of Empy was infected by Zombies and the Government decided to research a cure.
In the initial stages the infection was successfully contained to about 200 million that was about 25% of the population, helped by cure missiles launched by neighbours in the West Pacific. The Government of Empy itself also sent assistance to other nations in the region.
After 7 hours of the apocalypse the number of zombies suddenly rose to 331 million infected that was 38% of the population. The researchers started to rush to develop a better cure however a mysterious failed experiment resulted in Empy being suddenly teleported to the Rejected Realm. The high infection rate of the Rejected Realm resulted in the Zombie population spiking to 428 million people or 49% of the population. As the border of the West Pacific had been locked down by the Zombie Border Control, return was not possible resulting in a massive panic by the residents of Empy.
After a suggestion, Empy decided to relocate to Lemuria where the lower infection rate resulted in the gradual fall of the zombie population. In the meantime of calm the researchers sucessfully developed the Cure Missile Mk V that was used to cure Zombie population in neighbouring regions.
After 17 hours of the apocalypse the Zombie population was reduced to 0 by the cure missiles of neighbouring nations in the region.
The Apocalypse continued for 19 hours more in other regions but fortunately there was no relapse of the infection in the nation or the region. There were no loss of lives due to the Apocalypse.
