Is It Reasonable for Me to Have the Ability to Kill Through World of Warcraft with One Sword?

I'm just an ordinary swordsman. My sword does need to be nourished with blood to make it stronger, and it does need to absorb a fresh dead soul every day to grow, but I am not a bad person. The first time I fused the Red South Stone with a sword, I got the Ghost Sword, so I secretly killed my own city lord and obtained the supernatural power of returning soul. Then I became the new city lord. All the people in the city were happy, because I sacrificed the unhappy people with swords. While I was constantly absorbing dead souls, in the end, because I killed the city lord of the outer city who cared about me the most, the Ghost Sword broke through and obtained the advanced superpower Blood Sacrifice. At this point, sacrificing blood to the sword has become a road of no return. Although he is called the Ghost Sword Immortal, the World of Warcraft, the King of Slaughter, etc., They all still remember the words I say most often, "You like to bully the weak, and I like it too."
