David had long since evolved to Emperor Level.
People from Witch Star evolved to Emperor Level easily because after they generally evolved to King Level, with the extension of their lifespans, they had enough time to accumulate evolution resources and slowly evolve to Emperor Level.
The evolution resources needed for genetic evolution from King Level to break through to Emperor Level are hundreds of times more than those required for King Level, a massive amount.
Earth's resources are limited, and evolving to King Level is already difficult, let alone progressing to Emperor Level.
In recent years, David has put a pause on genetic evolution, instead seeking other ways to enhance his overall combat power, such as cultivating spiritual power—a bottomless pit that has cost a considerable amount over the years with little to show for it.
Additionally, seeking high-level equipment, weapons, and jewelry is the best shortcut.
