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

"May I ask if the host wants to cultivate the Ancient Devil Tome?"

"Cultivation of the Ancient Devil Tome begins:"

"Congratulations, the cultivation of the Ancient Devil Tome is successful. The host has cultivated to the first level."

The Ancient Devil Tome had a total of five levels, and each level upgraded would greatly enhance the user's strength.

Ye Li felt the devil energy within him growing stronger, several times more powerful than before.

Now with the Dragon-Slaying Blade, he believed he could fight against a fifth-tier Evolved Being.

He never expected that after eating the Purgatory Fruits and filling his stomach, he would obtain such an amazing tome.

Ye Li thought that when Chen Qi informed Shi Yuan of this matter, Shi Yuan would probably turn livid in anger.
