Apart from those abilities, the Eight Forbidden Blood Art had the ability to create life and devour all kinds of powers. However, the prerequisite was that one had to have devoured the same bloodline, and it was not bound by any laws.
As long as one worked on this bloodline and devoured countless other bloodlines, even the lowest-grade bloodline could become an Origin Bloodline, but it was incredibly difficult.
Moreover, there were no restrictions on what could be devoured – anything could be devoured, and at its final stage, even heavenly laws, or worlds' consciousnesses, could be devoured, allowing one to control the energy of a world.
That was how terrifying the Eight Forbidden Blood Art was, and it was because it was so terrifying that it was called an Ultimate Forbidden Art by the Outer World's sovereigns.
