Calming himself down, Leo decided to ask the crystal a question that was bothering him, since he absorbed Nux's Qi.
'System, why did I get much energy from Leo, and a few from the other cultivators? Is it that Nux's dantian is larger than Alex's and the others? They are in the same realm, then shouldn't the EXP I got from all of them be a little bit more or less equal? '
This question had been bothering for some time now, but he had been looking for the right time to ask this question.
Now is the time, he needed that answer for his mind to be at peace.
'As you must have seen, Nux was completely different from the other cultivators you killed, He is a necromancer. But that alone does not answer your question'
'You see, those undead you fought are made up of an energy and essence called, Abyssal Energy. This energy, or should I say essence, is because it's more of an essence than an energy, but people mostly call it abyssal energy. '
