B-rank Zombie's Evolution To A-rank!

After several minutes had passed, Winston, Ayame, and Kayden were concealing their presence while observing the B-rank zombie from afar.

They noticed that the B-rank zombie was about to evolve to A-rank and the chances of failure were very slim. Unless they were to interfere with the B-rank zombie's evolution then it would undoubtedly fail. But they didn't and the three of them just waited for it to complete its evolution.

After a few minutes had passed, the B-rank zombie released waves of powerful pressure throughout the streets as its viral energy burst out!

Winston, Ayame, and Kayden became solemn as they readied themselves for combat.

Winston took out his two C-grade pistols. His two E-grade pistols have been upgraded to C-grade due to consuming evolution crystals.

Special event items could upgrade their rank by consuming evolution crystals. It was a feature that Winston had already added to Zombie Survival Online since the release of the game.
