Story of The Ancient Demon King! - Chapter 26

18 years have passed since I was born as Allen, the eldest son of an earl in this world, while still retaining my memories of the present world. This world is peaceful and a stable society. The only extraordinary thing is that I was reincarnated into a world that is lenient on the existence of concubines. I selected a silver-haired maid as a sex slave and second wife candidate from among 10 candidates after a strict fellatio practical exam. I then lived an erotic life at home and at school as an attendant, but my reincarnated life is so fulfilling that I'm worried it will explode, as my busty childhood friend, a noble girl who was unsuccessful, ran for the third wife candidate, and my stepmother, who was my virgin partner, was sold off.

A 34-year-old NEET otaku, chased out from his house by his family, found that his life is reaching a dead end. He then recalled that his life could actually have been much better if he had made better choices in the past.

Just when he was at the point of regret, he saw a truck moving at fast speed, and three high schoolers in its path. Mustering all the strength he had, he tried to save them and ended getting run over by the truck, quickly ending his life.

The next time he opened his eyes, he is reincarnated to a world of sword and magic as Rudeus Greyrat. Born to a new world, a new life, Rudeus decided that, “This time, I’ll really live my life to the fullest with no regret!” Thus starts the journey of a man yearning to restart his life.

This is a story about the protagonist getting the system, going crazy in the biochemical apocalypse, producing aircraft and tanks, destroying zombies, saving good people and killing bad people.
