Travel through the end of the world and get a super-synthesis system. 

Two level 1 zombies can synthesize level 2 zombies, and the synthesized zombies are 100% loyal. 

The higher the level of zombies, the better their appearance. 

Zombies have exclusive skills such as fisting heaven and earth, and a series of three ghost swords. Zombies also produce zombie treasure chests every day in which good treasures can be unlocked. 

After Ye Li gained a super-synthesis system after the end of the world, he began madly synthesize zombies. 

The system is in my hands – it means I have the world. At the end of the world – tremble! My Ye Li is here!
