Alien: Create Your Own Undead Summons at the Beginning

Zaala's soul traveled to another world and became a dark mage. But I heard that there is no necromancy in this world? How can this work? Let's see how Saala creates his own necromancy and travels across other worlds! "What kind of creature is this immortal skeleton? Damn it, everyone in our group was killed by him!" The leader of the Shadow Bounty Group shouted. "Who is this mysterious mage? He is scarier than me." The Demon Queen gritted her teeth. This novel and its characters are purely fictitious.
