No one could wield the name of an entire Royal Family other than the Royal King himself, and precisely, that was the identity of the man with the poisonous sword and dagger. He was none other than the Alchemy Sword Royal King, a direct descendant of the Seventh Emperor of the Godslayer Humankind, the Alchemy Sword Emperor.
The Alchemy Sword Emperor had controlled the Godslayer Humankind Empire before the rise of the current Golden Emperor. He had reached the absolute peak in two aspects of cultivation: his swordsmanship and alchemy, merging the weapon and profession into a battle style unique to him.
This supernatural martial style intertwined the refined artistry of swordsmanship with the arcane secrets of alchemy, focusing on the creation and utilization of various toxins and poisons that could be flawlessly deployed through sword skills.
