Without the Dimension Scroll, directly absorbing the fundamental power of the Genesis World was far too difficult.
As freakish as Ling Han was, and even though he had already come across Void Particle Energy before, it still took him upwards 1000 years to finally attract a single Void Particle. However, this was only the beginning of his pain. The explosion of chaotic energy left him severely wounded.
Ling Han continued to cycle through this process. He would attract a Void Particle with much difficulty, and then he would suffer severe wounds after withstanding its chaotic explosion. He would then continue to heal his wounds as he extracted the particle's energy to temper his physique.
Without a doubt, this was an agonizing process. However, Ling Han could indeed feel his Body Art improving. Even though this was a slow process, one that couldn't compare to extracting energy from the Dimension Scroll, it was still like opening a treasure chamber.
