As a Sword, I Just Want to Upgrade It Properly

Lin Zheng, the coach of the kendo gym who died suddenly, turned into an ordinary iron sword worth only fifty coins on the blacksmith shop floor when he opened his eyes. No arms or legs, no words. [Innate Spiritual Treasure Growth System] activated! Swinging the sword a thousand times will increase the points, killing the enemy will increase the points, and swallowing the treasures of heaven and earth to temper the sword body. From ordinary iron to fine steel, magic weapons, spiritual weapons, fairy weapons... All the way up to the level of innate spiritual treasures, the path to immortality! What's even more outrageous is that every time you advance to a level, you unlock unique abilities that defy the heavens: All iron can be blunted, and it can trap evil and help good; The fine steel gives birth to the sword spirit and is blessed with power; The magic weapon controls the sky and chooses the master, and the spiritual energy shield; The spirit of the sword is thousands of miles away, and the mind is connected; The Tao of Immortal Weapons contains an edge that can kill gods and destroy delusions; The acquired spiritual treasure is immortal in origin and contains the universe; The innate spiritual treasure is invincible and controls space. From then on, there was an evil sword in the ancient continent that was specially designed to pick out its master: Encountering a loyal and virtuous swordsman, he secretly sharpened his sharpness and cut off the bandit leader's sword with one blow. The opponent was shocked and shouted "The magic weapon appears"; Falling into the hands of ferocious bandits, he was turned into scrap metal on the spot, and he personally sent the evil master to the sword of his enemies; Found by the righteous heroine, she instantly transformed into a caring sword spirit, helping her break through the realm and protecting her from a second-rate warrior to an innate master. I don't know how many years later, the three realms of immortals, demons, and demons fought to seize this sword, turning the world upside down and causing bloodshed. In the center of the whirlpool where everyone was fighting for it, the light of the sword suddenly surged, transforming into a lazy young man, smiling as if he was harmless to humans and animals: "Don't grab it. Don't delay me from proving the Sword Ancestor. "
