Bloodline transformation was not that easy.
The more powerful a race was, the more difficult it was to do so.
Moreover, he would have to pay a huge price for it.
If an expert wanted to abandon their bloodline, their cultivation level would fall at the very least, or they would suffer a backlash and die, never to rise again.
Generally speaking, the replacement or transformation of bloodlines was to use a stronger bloodline to devour the weaker bloodline.
However, the demon race was a strong race.
In the entire chaos, only chaotic beings were more powerful than the ancient demon bloodline.
Among the many races, only the human race was special. They could refine stronger bloodlines to strengthen themselves and further improve their bloodlines.
It would not diminish the essence of the human bloodline, merely strengthen it.
