I Summoned Myself into the Undead

Shen Yuan, who had no talent awakening, accepted the inheritance of the Great Sage of the Undead and became a Necromancer because of a dungeon exploration. At the same time, he was imprinted with a curse and would become the summoned object of the Great Sage after his death. However, just after awakening, he was imprisoned for life by the Holy Church because the necromancy spell would defile the corpse. While alive, he was a caged bird of the church, and after death, he was a prisoner of the undead. What will he do when he is reborn and comes back to accept the inheritance? "I sacrifice myself to myself" "I will be my own summons" I will never be anyone's puppet in this life. [System Reminder] [You have become the ninth largest race in the world, the undead]
