I Use My Broken Sword to Control Destiny

I'm not a genius. I'm just a waste who turned myself into iron. The world is a giant "funnel prison." The Tiandao Sect hung high in the clouds, pouring the spiritual energy and exhaust gas down, cutting off all the martial arteries of mortals. My name is Shi Qingfeng. My meridians are all severed and my Dantian is shattered. I was sentenced to death by this era and my body was mutilated. Cultivators wear body-protecting Gang Qi and take lightness as their way. They are jade. And I use poison to temper my bones, and use scrap iron as a sword. I am a rock. They majored in fluid mechanics, but I only believed in mass, kinetic energy and friction. Since I can't take the "red line" path of cultivating immortality, then I will use this 60-pound black ruler without a tip to smash this heaven, this earth, and this unfair destiny in this abyss full of garbage. ——In order to live like a piece of iron, I first killed myself as a human being.
