Traveling Through Another World, I Can Recycle Waste and Cultivate Immortality

As an earth traveler, I have become the worst-qualified five-spirit-root useless casual cultivator in the Tianyan world. I was forced to become cannon fodder, but I unexpectedly got the incredible opportunity to turn waste into treasure. I can directly swallow the alien energy contained in all metallic substances in the world to improve my cultivation. The speed of my cultivation is far faster than the transformation of spiritual roots. From then on, I appeared to be a weapon refiner, but in reality I was secretly devouring discarded scraps crazily. Others discarded them like worn-out shoes, but I regarded them as treasures. The three major sects were fighting endlessly for the chance to find the remains of the ancient sects, but I was targeted by the chief goddess of the Yuling Sect. She invited me to join the sect and work together on great things: "Work for my Yuling Sect and I will give you two golden elixirs." Later, when I took control of the secret of the ancient sect formation, the Jinyang Sect who was chasing me was shocked: The useless cannon fodder they forcibly threw into the secret realm back then has now become the evil star that kills them. —— Looking at the countless strong men kneeling at my feet, I waved my hand to activate the formation: "Please, all of you, go to death and transform me into a ladder for ascension!"
