Hey, I heard that the sci-fi novel "Necromancer, but Man in the Interstellar Era" is very good! The main character could eat insect monsters, punch mechas, tear battleships with his hands, summon powerful undead creatures such as bio-type hulls, self-destructing bug tracking grenades, flame bug biological missiles, predator anti-infantry mechas, and so on. After fusing with technology, he could rule the entire interstellar civilization. There was also a sci-fi novel called "Doomsday Mage Summons the Undead". It was about the protagonist becoming a Necromancer in the apocalypse and forming an undead army to conquer the other world. Other than that, there were also novels such as "All People: My Necromancer, Unlimited Upgrade Skills" and "From Undead Skeleton to the Ultimate Boss", which were also very exciting! I hope you like this fairy's recommendation. Muah ~π
