Apocalypse: I Have a Zombie Upgrade System

The Xu clan has been living independently in the zombie world for a long time, but one day a system was suddenly activated. What's even more surprising is that it turned out to be a dual system. What's so scary about zombies? They should all be afraid of me! After acquiring skill points, you can control zombies as you like. The system has been upgraded, and the zombies are afraid of me and will automatically provide me with skill points. The system has been upgraded again, and this time I can actually call all zombies to obey my orders. The system was upgraded again and I inspired the advanced system. "I heard that there is someone who can control zombies. Let's go and join him." "They say there are enough people, let's go ask how to hug the thighs."
