"Once upon a time, there was a knight. He was known for his purple plate armor with a mace and shield. Many people saw him as a hero, killing monsters left and right and while making tons of money which in turn many wanted to kill him, but however he disappeared from the face of the world. Adventurers searched far and wide as rumors of his wealth was unimaginable. Riches upon jewels and coins. Armors made of the rarest minerals. Skills that transcends the gods and demons." - some random merchant passing rumorsIn reality, he was sleeping for 6,000 years because his skill which turned mana into energy for his body made him numb to mana which could be reset over time. He killed most demons is because many of them were already close to being dead. The only good thing he had was a skill that made him live as long as most dragons. He studied this skill so he could use it as he had a bunch of free time. This skill is not extremely hard to get. He's at later stages due to him killing demons which gave him more mana to take from and make him power level through it quickly. His cheap iron armor was purple after accidentally falling into a pool of blood of a low ranked demon.And when he does return, he will become stronger and when he does, he will ascend past his plant towards a greater galaxy. Also his wallet is empty.
