Versatile Mage: the Undead I Summoned Are Zombies

[Multiple heroines + invincibility + genius + ease] Jiang Yuan traveled to the world of full-time mage and had an undead system that was different from others. Others summoned the undead, but he summoned zombies. He possesses the undead system and possesses the souls of the ancestors of the four zombies. Servant general, my green zombie and black zombie can destroy him. Commander-in-Chief: My jumping zombies and flying zombies can be easily killed. Is the Supreme Lord strong? I'm sorry, but my bone-shattering and flying stiffness are even better. No matter the emperor dominates or even the roof, the four zombie ancestors will tell them who is the protagonist of the era. The Holy City, which has the strongest ability to restrain the undead, is as insignificant as an ant in front of the four ancestors. Even the powerful archangel in people's eyes could not survive for a minute in front of the ancestor zombies.
