However, the hero who has been given the skill "Human 80 years" takes advantage of his longevity and takes over the skills of many goblins and even the demon king who is on the verge of destined life, and stands out in a different world. Weakest Race x Strongest Skill = The strongest fantasy is incomparable!
Solid 9/10, better than Re:monster

Ira Takuto succumbed to illness at a young age and ended up reincarnating in a world that resembled the strategy simulation game, ?Eternal Nations?, of which he loved playing when alive. What appeared in front of him was Atou, a girl belonging to the evil civilization that he used to play as, ?Mynoghra?.

MC reincarnated as the daughter of a low-ranking concubine of the Joseon king. She has gained the king's love.
For now 8/10. It’s still early in the story, so needs to marinate longer.
Update :
Read a spoiler mentioned that the CP will die, because the 3rd prince is the CP in the novel (the Mc is reborn inside the novel she read before she died and she remembers it after know the 3rd prince name)
Drop it for now will read again after a year.
