Heavenly Way of Blood and Fire

In this rotten world, human life is like grass. Lu Wu traveled through time and saw that this world where martial arts were respected and demons were rampant was like falling into an endless purgatory. Without strength, he and his sister are just fish on other people's chopping boards. Fortunately, a blue light curtain in his mind became his only hope. Darker blue, martial arts reach the sky! "My achievements are all on my own" In this world where people cannibalize people, he wields the knife in his hand and cuts out not only an edge, but also his own way to survive. "The sword cuts all evils and defeats all sins with force. Deep Blue, give me some extra points!"
