Tank Factory!

Zhao Yu didn't expected that the newly refreshed daily mission was to clear out zombies.

"How can there be zombies in this world?!"

Zhao Yu instinctively felt it was impossible according to his past memory and journey. After thinking for a while, Zhao Yu considered the system must be changed the naming of mutants according to his understanding.

Just like aliens, even though they were created by the people of this world, the system named it based on his understanding.

This undoubtedly indicated one thing: the scientist of this world really crazy to actually create something similar to zombies.

Even if it were zombies, he had to complete the task.

This world was indeed very chaotic, with different species, aliens, mutant beasts, and radiation beasts, and now there were even zombies.

Even if some bizarre creatures appeared in the future, Zhao Yu might not be surprised anymore.
