“Who’s this male prostitute-looking kid?”

I am the matchless Ha Hu-Yeong, the greatest martial artist reigning over all the lands! There is no one that is my equal! I was drowning in futility and emptiness because there was no more that I could accomplish in the human realm. To reach the peak of martial arts, I must become a saint!
However, the other saints refused my ascension due to my karma after much slaughter, and I fell, just like that.

When I woke up, I was 60 years in the future. I was reborn as the second lord of the Namgung family: Namgung Hyuk. Where has all the internal energy that I’ve accumulated gone?! Moreover, I have the Nine yin energy blockage?
