Death

In the universe, or rather, in the entirety of creation, any and all things could happen.

There were multiple phenomenas that constantly occurred that cultivators partook in, without questioning the source or origin of such events.

For example, Blood force.

What was blood force? What was force? Why did they need to become Primogenitors to ascend into the next realm? Why did need to assimilate other bloodlines? Why not use Life force instead?

The answer to all these questions tied into one another and was extremely hard to answer.

Blood force was many things but to explain it, one must first understand what force was.

Forces existed in all types, there was, obviously, Blood force, which governed the body, Soul and spiritual force which governed the ethereal and the soul and there was even Dream force which governed the realm of dreams and was closely related to matters of the soul.
