Invincible at the Beginning, Why Is It All in One Blow?

I was trapped in Novice Village for more than 20 years. When I came out of the village, I found that I could hit anyone with a single blow... It turns out that although my level has not improved, my attributes have been improving... What, my attributes are the best in the world? Han Bin never imagined in his life that after twenty years of killing demon dogs in Novice Village, he would become invincible when he came out. Why is there always a girl following him? It's so annoying.
