"System, can you tell me what that special energy pertains to?" Rezen asked, trying his luck
[No] the system replied in an instant
"Why do I sense sarcasm?" Rezen wondered. It really feels like his system changed after the farm's upgrade
Rezen knew that it would be useless to try and get an answer from the system and he can only do the next best thing
"Black Dancer, Shadow Dancer, check that black snake corpse and see if you can sense strange energies from it" Rezen ordered and he watched as the two tried to inspect the corpse
"Sir Rezen, there is indeed a remnant of strange energy on this corpse but we don't know what or where this energy comes from" Shadow Dancer replied causing Rezen to frown
If even elite 5th fusion rank mages can't understand what and where these energies are coming from then there is really something fishy about these black snakes
