Lucian decided against absorbing any world energy and putting it to the test, instead, he looked at the method in the tome for how to cultivate 'Destitution of Souls' and took the little bit of energy that existed inside his core and started to weave it according to the method of the technique.
The process was difficult, for the technique was of the legendary grade, which made it a long and cumbersome experience before Lucian was able to get it right he pressed the energy against his lungs and immediately felt like he was suffocating.
Lucian held his breath and repeated the process once he recovered his mana, then he extended a tendril of it out to his core, as soon as he did so he could see a sliver of whitish pure light buzzing in a chaotic state, it moved along his mana using it like a pathway to his lungs then a second sliver emerged at a slow pace.
