There were quite a few peak cultivators or Yan Immortals who used this unique ability to cultivate their own techniques.
This secret technique was extremely powerful. The only drawback was that the external force absorbed was too complicated, and it required constant time to digest and purify it.
However, there was a simple and crude way to deal with peak cultivators or Yan Immortals who relied on this secret technique.
That was to use all his strength to release his Yan power and cause his body to explode.
This method was indeed feasible, but if he was not careful, it was very likely that he would be killed.
Thus, even if a Yan Immortal knew of this method, he would not try it so easily.
Facing nearly 30 Death Immortals, Shu Yang did not even dare to breathe loudly.
They could not feel pain. Even if their limbs were cut off in battle, they could still release the last energy in their Immortal bodies.
