God-Level Treasure Refining Expert

The "Treasure Refining" system sent from heaven can refine all things! Put your body into the system and practice it, and you will be instantly invulnerable and as strong as an ox. Throw a dog into the system and train it, and it will immediately defeat ten tigers! I refined a copy of "Six Meridians Divine Sword" I bought at a roadside bookstall, and it instantly became an immortal-level swordsmanship book! The protagonist's road to invincibility begins!
