A World Where Only Brave Men Cannot Use Magic

After traveling through time and becoming a fourth-generation warrior, Roland discovered that he was a "waste" who could not use magic. Fortunately, he has his own golden finger [The Cast of Reason and Law]. Extract the terms from the corpse of the monster, give [sharpness] to mortal iron, and integrate [armor breaking] into the arrows. The price is that his body will gradually crack like porcelain, using it once and breaking an inch. When he finally left the border town, he discovered that the truth of the world was far crueler than imagined: monsters were not disasters, but the world's immune system used to suppress "magical pollution." The more he used it, the faster the end came. What's even more outrageous is that the previous three generations of brave seniors are each more unreliable than the last. The first generation of heroes set the rules and disappeared immediately; the second generation was a lone chatterbox who buried "voice easter eggs" all over the world; the third generation was even more amazing. In order to let his cowardly twin brother feel at ease as a "waste hero", he personally built an "eternal kingdom", which directly locked the magic limit of the entire world. The Eternal Kingdom prohibits latecomers from touching the Holy Sword. The shadow of the third generation of brave men shrouded the entire continent. Roland looked at his cracked hands, and then at the group of equally unreliable companions around him—the third prince of the empire who sang out of tune, the elf hunter who never paid for meals, and the old mage who could never remember who the murderer was in detective novels. "So, my current generation of heroes not only have to save the world, but I also have to clean up the mess of the seniors from the previous three generations?"
