Castlevania

My name is Fang Sanhen, because I have three cruelties: cruel people, cruel hearts, and cruel treatment of myself. I have traveled through time twice. Once I traveled to my real boss, and the other time was delayed for 200 years. During these 200 years, I fully trained myself to become powerful, and obtained a Castlevania system. I also became the 13th generation Demon King, which can continuously strengthen my subordinates. Goblin: "Brother, we are just scaring people, there is no need to do it, right?" Fang San clamped the goblin's head hard with his shoulders, as if it would be strangled in the next moment. "It's impossible for everyone to join the Demon King and kill us all." Fang Sanhen: "Sir, would you like to ask if my Vulcan Cannon will respond?"
