Dungeon: Brushing Metal Slime

The spiritual energy is revived, everyone is good at martial arts and Mana, but I am the only one who is a natural loser with zero Mana. Until my backyard grew a unique [Elevator Shiki God-level Dungeon] in the world! Others rely on forming a team to download a dungeon, but I download a dungeon, and the dungeon will rise by itself every day! The first level: Metal Slime → Obtain [Indestructible Body] Level 100: Color Slime → Obtain [Full Elemental Resistance MAX] Level 400: King of Slime → Obtain [Infinite Transformation·Liquid Metal] You can eat as much as you want of top-grade magic ore. Others can't get even one if they ask for it. Even I have too much to put on the table! Genius Fa Xiao said: "Fang Wu, work harder and try to break through Mana's 10 points as soon as possible." Me: (awkward yet polite smile) "Oh... Ok." (Inner OS: Sorry, I just finished the measurement yesterday, and the Mana index was 460,000. It seems that the world's most powerful measuring instrument was dried out...) When my magical power is completed, the devil will be born! "I'm sorry, but this magic of yours... Can you break my defense?"
