God of Assassination, Become the Strongest Healer

I became an assassin for revenge and achieved my goal, but there was too much tr*sh in this world. I shed blood for decades with the intention of purifying this dirty world, and when I finally became known as the God of Assassination, I met my end with the greatest tyrant who dreamed of unifying the continent. However… ―If in this life you focused on saving the weak through death, then in your next life it should be the opposite. With ‘healing’ rather than ‘blood’… I was reborn as a descendant of the greatest medical family on the continent, leaping over 100 years.
