Heavenly Martial God

“Who’s this male prostitute-looking kid?” I am the Matchless Ha Hoo Young, 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! “I finally succeeded!!!” “Stop! Your ascension is not permitted!” 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 Namgoong family, Namgoong Hyuk. Where has all the internal energy that I’ve accumulated gone?! Moreover, I have the Nine yin energy blockage?
