Hundred Battle Green Armor

Ye Li was transmigrated into a zombie world and acquired a zombie synthesis system.
Two level 1 zombies can be synthesized into a level 2 zombie, and the synthesized zombie is 100% loyal to its creator.
The higher the level of the zombie, the more attractive its appearance.
Zombies possess exclusive skills such as the Earth-Shattering Fist and the Deadly Triple Ghost Sword.
Zombies also produce zombie treasure chests every day, which contain valuable items.
After obtaining the super synthesis system, Ye Li began crazily synthesizing zombies in this world. With the system in hand, I reign supreme!
Zombies, tremble in awe! I, Ye Li, have descended! 

Apocalypse: God-level Zombie Synthesis System

The other dozen or so men were all 1st-tier Evolved Beings. How could they not recognize the levels of the four zombies beside Ye Li?

7th-tier zombies, these were 7th-tier zombies!

These dozen 1st-tier Evolved Beings were so scared that their souls seemed to leave their bodies. Their entire bodies were trembling violently. They wanted to run inside, but they found that their bodies had no strength left.

"Leave one alive, and kill the rest," Ye Li told Ah Da.

After receiving Ye Li's order, Ah Da swung his fist forcefully.

After a loud noise, these dozen or so 1st-tier Evolved Beings instantly died in misery.

Just as Ye Li ordered, one 1st-tier Evolved Being was indeed left alive.

Luo Li was dumbfounded. She had heard about the levels of mutated zombies.

Zombies of level 1-10 were ordinary zombies.

Those above level 10 were mutated zombies.

Mutated zombies included 1st-tier and 2nd-tier ones.
