Doomsday: Zombies Evolve, What About Humans?

This is a world parallel to Blue Star, but a virus here that should have passed has mutated into a zombie virus. They are looking for humans everywhere. They do not use death as their instinct, but instead aim to infect. "Report to superiors! The surrounding people have been persuaded to leave, but a C-class zombie was found! Requesting the use of heavy firepower! Requesting the use of heavy firepower!" "Copy that, be careful not to destroy key targets, and blast the rest!" All carbon-based organisms are equal in the face of heavy firepower, but what about silicon-based organisms? "Report to superiors! The C-class zombie... It has evolved!" "Report to superiors! Class B zombies are not afraid of tank bombings. We can't leave." So zombies have evolved, what about humans? This novel and the plot of the characters are purely fictitious.
