The Straight Road to Heaven

[Legacy inheritance + fortunate encounters + no System + settling scores with abandon + decisive and ruthless + invincible in the later stages + a knife-wielding youth]

So what if I was born with no talent for martial arts? I inherited the legacy of an ancestor, and a Holy Spirit chose me as its master. From then on, I rose to power, obtained a demon blade and a demon stone, and strapped a sword to my waist to cut down the peerless young prodigies.

I wield a blade that can cleave the heavens!

I am invincible, mightier than the sky!

I devour demon cores and turn decay into glory, growing stronger through adversity. I slay the Demon Eye and quell chaos. I am the greatest miracle beneath heaven.
