Honghuang: I Can Change the Levels of Magical Treasures

He transmigrates into the primordial world and takes over the body of Ao Yue, crown prince of the Dragon Clan.

By chance, he obtains a modification System that lets him change the grade of any magical treasure at will.

Laozi of the Taiqing Palace: “Just what grade is that bottle of yours? How did it break even my Taiji Diagram?”

Celestial Worthy Yuanshi: “Impossible! It's just a little leaf. How could it possibly suppress my Pangu Banner?”

Sect Master Tongtian: “You're bringing a kitchen knife to fight my Four Immortal-Slaying Swords? Are you trying to make me laugh? No way! How did your kitchen knife damage my Four Immortal-Slaying Swords?”

That day, the countless mighty figures of the primordial world stared at the mountain of Chaos Treasures, World-Creation Treasures, and top-grade Innate Spiritual Treasures in Tang Yue's hands, lost in thought.
