I Am Such An Expert; Why Do I Have To Take In Disciples - Chapter 29 - : Avengers Alliance

We follow Anthony, a man forced to adapt to a world of dark fantasy that imposes itself on him with an unmistakable brutality. A place where shadow and violence reign supreme, where inequality is riven and the laws of nature are distorted. A world where every moment could be the last.What fate does this cruel universe hold for our protagonist? What hidden secrets do the powerful hide behind cold and inaccessible masks? And what alliances, betrayals or rivalries will be woven into this maelstrom of supernatural forces and unfathomable powers?To survive, Anthony will have to fight, evolve and face his own demons. For in this place, no matter the greatness of the beings that populate it, it is tenacity that dictates the law.

With the revival of spiritual energy and the breakdown of the order of species, it is a difficult test whether human beings can still stand at the top of the biological chain.
