What is the concept behind 'buffy slayer drank my cum fanfic'?

Lu Wu, an aimless video game developer, had been feeling perturbed ever since he found out he was the direct descendant of a king from the underworld. Other than the title, His Excellency, his ancestor hadn't passed down anything else to him. On top of that, all of his ancestor’s subordinates had rebelled against him and completely usurped his inherited territory. Under the circumstances, Lu Wu built a battle game server with the help of his new mysterious friend and transported gamers from the real world straight to the underworld using virtual reality. They then created the main quest, the character classes, the Instance Dungeon, the storyline, and the non-player characters for the game. Relying solely on these video gamers’ strengths, Lu Wu began his expedition to reclaim his rightful inheritance. What could possibly go wrong?

April was sure he died after getting assassinated on his way home from school. He wasn’t expecting to wake up in an orphanage, in the body of April Frost, in a parallel world. The world resembles his old one, except the supernatural is not just a story, although hidden, and he has some connection with it. Bad news though, he’s supposed to be twenty but he’s stuck in the body of a thirteen year old, both mentally and physically. It’s not all bad though since he has a system that supports him; the [Slayer System]. The more enemies he defeats, the stronger he becomes. One day, the orphanage April lives got involved in a territorial dispute between demons and vampires and became collateral damage. The only survivors were him and two others; Sylvia and Klint. *** “I will make them pay. I will become the strongest and I will make them pay!” *** April, Syril and Klint, ends up under the care of one Sakura Tsuchimikado, the famous Witch of the East. Under Sakura’s care, April and a few others investigate cases revolving around the supernatural, providing April with plenty of enemies to fight making him stronger and closer to his goal. But just as he and his comrades got into a rhythm, problems arise which involves the higher echelons of the supernatural and at the very center of it is April with his mysterious power. Will April become the strongest just as he desires? ******* A/N: This is an original fiction story. Although a few elements may seem familiar, it is still a fact that the events in this story came from the author's imagination. Also, I welcome honest and helpful reviews, comments and power stones. And feel to stick around. P.S. Cover was found on google and edited on Canva. Xoxo, Bai_Wu_Yue

A guy dies and is reincarnated into a random world he only slightly knows with three wishes. See how he uses his abilities and magic to become absolutely broken in the world of Fate/Stay Night. Just so everyone knows, this is going to be a harem novel and the harem won't exactly be small. Each girl will have her own screen time but don't expect in-depth character arcs with all of them. This novel is my side-project, so don't expect regular updates.
