In order to protect his current family and prevent the pain he experienced in the past from happening again, he decided to work hard to become stronger. Inside a black sword lived a dead demon king, a girl who wanted to die, a woman looking for her father, a child who ate a lot, a kidnapped silver wolf brother and sister, an A-level adventurer who didn't want to associate with anyone... After the demon king disappeared, the vampires became the masters of the demon realm, and it seemed that there was a bigger plan being implemented. If the vampire becomes the ruler of the world, then his family and friends will also suffer unreasonable disasters. Can Lake gather powerful teammates to stop the vampire's plan?
