Isekai Kaeri no Ossan wa, Fusei Sukiru de Fathercon Musume-tachi o Tororori ni - Chapter 19: Rebellious Phase!

Vergil, a 21-year-old young man, leads an apparently simple life in a somewhat troubled world. His family is also simple—although his father is no longer alive, his mother has always been by his side, despite being a bit... aggressive. But that's not so unusual nowadays, right?Everything changes drastically when Vergil, after an unexpected death, awakens as a demon. To his surprise, he discovers that he has accidentally married beautiful Pure-Blood demonesses.Now, he will discover how the world really works from a Demon's perspective.

In her past life, Chen Wei’er was too blind to recognize people for who they were. She caused the destruction of her own family for the sake of a scum, and hurt the people who truly loved her. Fate gave her another chance to start over. In this life, she became decisive and worked hard in her career. She became a proud dance queen who managed to destroy the third-wheel who schemed against her, take revenge on the scum, and avenge all past grievances. She became a sweet wife who was coquettish and flattering, boldly seducing her aloof husband, He Xun.

His difficult wife suddenly became sweet and gentle. He Xun finally couldn’t resist holding her tight and whispered into her ear, “What do you want? I’ll give you everything. My life is yours too, so stop teasing me…”

One night, Chen Wei’er had a dream. She dreams of her past life, and the world after her death. He Xun was sitting in the hospital’s corridor, hugging her bloodied corpse as he went insane. “Had I known that in exchange of letting you go, you would die instead of being happy, I would never have let you go…” Then, He Xun killed all of her enemies and built a small wooden house in front of her grave. He never took another wife but became her grave-keeper. To think he loved her so much. Then, she learned that fate only gave her another chance to start over because this man, who had loved her for two lifetimes, had begged in front of her grave day and night for another chance in exchange for a lifetime of loneliness…

The young man was so ridiculed for his wasted blood aptitude. Once he awakened the supreme bloodline, the dragon flew into the sky!

From then on, the geniuses and martial arts giants all bowed their heads, and the nine heavens and ten earth trembled!

Condensing the supreme Taoist body to achieve supreme power!

One finger penetrates the plane, one sword slashes the galaxy, one thought swallows the starry sky, and holds the avenue for eternity!

The harem would not be too large(I'm not sure how many but probably just 4-5 main and few other here and there). All the girls would be getting their time and story.2. The story is starting when the MC is in the middle of his growth stage and not at the very beginning. But his beginning will be mentioned in the story in some form.3. I don't think I need to mention this, but obviously it will not have any NTR, rape or that kind of stuff. It is actually quite a wholesome story focusing mainly on adventure, action and bit of romance and slice of life.
