This path was, of course, not easy to walk. Not only was the risk extremely high when refining the physical body with the blood of Different Species, but the time and energy consumed was also more than that of Zhou Qing and the others directly refining their bodies and souls with spiritual energy.
The most simple example.
Take the risk of refining the bloodline with the elixir of the Different Species for example; it is inherently dangerous, so it would be impossible to take too many elixirs at once.
For safety reasons, martial artists would take one elixir a day, so that the power of the Different Species' bloodline is neither too strong nor too weak, just enough to refine the bloodline without exceeding the martial artist's control.
To calculate, completing one body and soul metamorphosis would require the support of 500 elixirs.
It means, if a martial artist wants to break through Innate, it will take at least 500 days at the fastest.
In other words.
