Her tone was dismissive as she said, "The amount of world essence they got from killing world guardians was little compared to killing worlds. It was probably around 0.1%. But it was better than nothing."
"Plus, this method was usually safer than invading and attacking an entire world. So it was a viable alternative to invading worlds."
Then she shrugged and said, "Either way, the method of advancement didn't really matter. World guardians and world killers at the Divine Transformation stage both had Domain Power, which allowed them to enhance their power with the power of the world."
"I remember reading that Divine Transformation cultivators were stronger the higher the quality of the surrounding spiritual energy was. So I believe that some of their power was also dependent on extra spiritual energy."
