During his seclusion, Noah had experimented a lot.
The failures with his forgings sometime exploded, ruining Noah's robe in the process.
Noah didn't care about his ragged clothes while he was in seclusion, his mind was completely focused on his training but, now that he had to meet an elder, he had to appear somewhat presentable.
He was the Demon Prince after all, he couldn't reappear after four years in that poor aspect.
"I think I'll call an outer disciple before going out."
Noah said as he sighed under Bruce's approving gaze.
The servants inside Noah's mansion quickly took care of his appearance.
They prepared a hot bath filled with many delicate perfumes to remove four years of accumulated sweat and dirt.
Then, they cut his hair a bit and combed them in a seemingly noble manner, it was pointless to say how bored Noah was through the whole process.
