Blood Essence

"What?"

Edmond was shocked to hear the demon servant's request in order to release the King killer.

He was not the only one to be shocked, Udo and Darbaudr were also shocked to hear that.

There was nothing wrong in Edmond and others to be shocked by the demon servant's insane request.

A cultivator, whether he belongs to the human race or any other races, when he enters the general realm cultivation realm or any corresponding general realms of other cultivation methods like spirit cultivation, Devil cultivation etc., he could convert his blood into blood essence that could be used in case of emergency situations or some near-death situations.

The blood essence of a cultivator helps him to heal rapidly depending upon the concentration of the blood essence.

However, it could not be used by any other cultivators other than the owner of the blood essence. In fact, it could be considered as a suicide to use another cultivator's blood essence.
