Necromancer's Tome of Healing

[Villain] [Decisive Killing] [Alternate World] [Sword and Magic] [Violent Soldier] This is a novel about the Western Middle Ages. Similar to novels about dragons and magic, heroes fighting demons, and justice triumphing over evil, they are somewhat cliche. But what if I mix all these together and make a hodgepodge, is that possible? Hmm~, adding my favorite farming. What? Still too vulgar! Then cut off the sacrifice book for everyone's favorite heroine. By the way, the protagonist must be a time traveler. As for the protagonist's character~? Of course he is a good person [liar].
